"It's getting late!

"No more! They were all waiting, weren't they?

Adele came back and everyone was there.

Let's check it out.

Where are you going to jump on your return home?

I'm here, on the south end of S5, on the unnamed relay portal.

Irina is the village of wind spirits.

Spring vegetables are the sand and dust temple.

Adele, this flower, Hyodle, anyone can jump into the gray forest.

What is it?

Was there any inconvenience in jumping ahead if you seemed to be late?

Fine.

Collective action is something I want to keep in the kitchen.

Finish partying and exit the instant portal to jump to the gray woods.

The person in charge of the spell is Hyodle.

MP Bar wise he is the toughest.

But he's the only one who still can't use the instant portal.

I want you to do your best.

"See you in the evening"

"Right."

"Say it!

In the gray woods, only Hyodle will log out.

It's not like I don't want to do woodworking.

Until evening, let's just say this is the most efficient way to restore the MP bar to its fullest potential.

I haven't been very conscious, but in terms of efficiency, they're nearly double different.

Spend about 10 percent in an hour caricaturally, without acting like a spell or other MP consuming behavior in the game.

They say it's double when you log out.

They have also found that the recovery of status anomalies is on an hourly basis.

I didn't know that, me.

I was in a hurry to open and search Red Lotus's report, and there was a similar hypothesis.

Wide.

But if I read it all, I'm afraid it's going to be a terrible story.

What a dilemma.

"Then we're here!

"You're making change as a cook."

Adele and Irina say they're opening a stall.

Even so, I just lined up my desk.

With the Item Box, you don't have to pull the stall and walk, do you?

Plus I wouldn't have trouble selling if I had meat I got from the hunt.

There is also the flesh of phantom horses and other useful beings whose flavors are subtle but not rotten anywhere.

"Then we'll be here."

"Meet me at this stall in the evening."

Spring vegetables and this flower helped a garment artisan I know with his workshop.

They can work on this anywhere as long as they have the ingredients as well.

They seem to carry rocky mountain sheep hair all the time.

Speaking of which, I've been working on spinning yarn in my spare time.

Food and clothing are still good.

Relatively strong against recession as well.

Well.

I'm free until evening.

Let's start by locating the sale at the dewstore.

I might have some new gear that I'd like.

I might get a lot of ideas.

Whatever it is, it will be worth looking around.

Before that.

Shall I call the Summoning Monster?

Wolf, Helix, Obsidian, Strand and Romulus.

For once, I've made it an uncompressive formation.

I'm not scared.

I'm not scared, am I?

I'm sure, I'm not afraid.

Then let's take a look around.

Anything interesting?

If you say there is one.

I don't have to say.

I know a merchant here before, Takefu-kun's outdoor shop.

Looks like there's more rubber gear.

It's a shield again.

The quality E is still low this time.

"Hi there."

"Oh! Summoner, no, Mr. Keith."

"Did you make this again?

"Yeah. It's like a failure once again."

"Hmm."

Because.

The surface is quite brittle.

I think it's new, but the crack was already occurring.

Touch that and the hardness varies considerably depending on the surface area.

That's not a good trend.

"That's a mess, isn't it? It just seems like a big mistake."

"I guess the heat you gave me to sulfurize was too big"

"Huh?"

"Plus, you don't seem to be doing so well."

"Do you know what to do?

"I don't know much about it. I can't say enough about not looking at the production site."

Yeah, yeah.

In this game world, all sorts of things can be done with magic skills and production skills.

I don't even think modern knowledge and rules of thumb will make sense.

"Could you give me a moment? I have a buddy who makes rubber."

"Ho."

Are you there?

Would it be a lie if I told you I wasn't interested in rubber products?

Somewhat, but I've been involved.

Well, if I saw the crime scene, I might be able to give you some advice.

It's a narrow rule of thumb for me, and it's hard to expect.

"Hi, I'm Lucan, Farm Leader."

"It's an alchemist and a cherry blossom"

"This is Kono of Blacksmith."

Apparently there are other fixed members of them, but it seems to be mainly this member who manufactured that shield.

There is a strange odor in the workshop.

The rubber is sulfurized, that smell.

They were currently just in the process of adding sulfur.

"I just want to borrow some wisdom about rubber!

"Do you know what you shouldn't do?

"No, I don't even think I can make a big point."

See what looks like a mold sandwiched in two plates with heat.

What's that thickness?

It looks like the thickness of the rubber embedded in that shield itself.

Isn't it nearly two inches?

"I think we're adding sulfur. Temperature?"

"It's about 200 degrees."

Sakura answered.

Are you a female alchemist?

The exterior is adorable that leads to Adele.

But there's the opposite atmosphere.

"Definitely too hot, huh?

But the fever didn't go through inside.

"He said it was with me doing an aging test on the vulcanized rubber surface. You should call this off now."

"Do you want to stop?

"Let's stop"

Two plates, and what emerged from inside the mold frame, were thick vulcanized rubber.

I've smelled it many times.

Obviously, it's super sulfurized.

"This time I put it at 200 degrees on the temperature test, is it another failure"

"What didn't you want?

"It's gonna be a little longer, okay?"

What's the problem?

The same goes for the sulfurization conditions, but that's not all.

You suddenly sulfurize such a thick substitute?

I think it seems simple and difficult.

"You have to lower the temperature to sulfurize a big substitute, hey"

"Are you lowering it?

"Shall I take the example of making fried chicken?

That's right.

The creation of vulcanized rubber can, in a sense, also lead to cooking.

You think it's where the heat is applied?

The same goes for mixing ingredients and such.

I tried to explain it as easily as I could.

Would you have made it through?

Here's what I explained.

Was there ever a lack of fire street and raw inside when making fried chicken?

I do.

That's what happens so many times.

It's ridiculous that I should use fried chicken as an example to explain it.

Well, put that down.

If so, what will you do?

Fried longer.

Sure enough, that'll get the fire through inside.

But the surface doesn't make sense because it burns.

What happens if you raise the temperature of the oil there?

It's just going to be worse.

If carbon is mixed with a reinforcer with vulcanized rubber, there is no way of knowing surface aging.

It's black.

The vulcanized rubber I used for that shield already had a crack.

It was even brittle all over the surface, and touching it was the cruelty you could see.

Oops.

The countermeasure.

How do I get through the fire to the fried chicken?

There are two means.

One lowers the temperature and takes longer to fry.

The other is to cut the meat smaller so that the streets of the fire are better.

Together they would be more effective.

"If it's natural rubber and sulfurized, it's 15 minutes at 150 degrees for a 2 mm thick sheet, and that's enough sulfurized."

"It's 2mm thick, is it?

"Right. And the thicker the subject to be sulfurized, the longer it needs to be."

"How much is it?

"By size. Shockproof rubber for buildings may be hung for more than a day."

Well, this is an extreme example.

The formula is quite different, too.

In addition, if stable rubber performance is to be produced, there are also hands that are vulcanized and affixed together with thinner sheet thicknesses.

But that would require a separate adhesion technique.

You should definitely sulfurize it in one shot.

"Oh dear, double the sulfurization time as the temperature drops by 10 degrees."

"Double?"

"By size. And shape, too."

That's not all.

Press pressure too.

The mold may also be heated up beforehand.

Though all changes affecting temperature should be taken into account.

Well, if it's a sulfur-sulfurization system, does it ever get nervous?

The problem is this thickness.

It would be easy if the shape were flat.

There is no sulfurization accelerator in it anyway, so is it at 125 degrees for 90 minutes?

Appropriate, though.

Nevertheless.

This vulcanized rubber, it's hard!

How much carbon did you formulate this?

No, is there also a lot of sulfur in the formula?

Hard means you need a lot of power to deform it.

Wouldn't it be hard to process it into protective equipment even if it was sulfurized?

The shield might still be good.

"So, what are the demanding characteristics in the first place?

"Eh. It's rubbery, repulsive, and it lasts about as long as a tire."

"Tires, hey"

Abstract indeed.

Besides, the ideal is the tire, and when it does, the hurdle goes up at once.

This is troublesome.

I can't help explaining it unless you understand it from the basics.

"Just a moment, okay? Maybe you should explain it at the previous stage."

"It's okay!

"Then should I explain it with a familiar rubber product? Whatever."

"In a condom!

I'd like to ask Muto.

I want to ask you a question.

I wondered why it was a condom there.

Are you that close?

Well, that's fine.

Sakura, I hope you don't look so subtle.

In a way, it's an easy question to explain.

What features do condoms require?

Whether it's sexual intercourse or not, it's about capturing semen without leakage and avoiding pregnancy.

It is naturally the most important feature required for the various condoms that line up as a product.

So, what about from a buying standpoint?

Assuming that all products can be used for contraceptive purposes.

What would you buy on the basis of with the various products lined up?

Also, why don't you look at it from a selling standpoint?

What would you appeal to and sell in?

That's right.

There are other demanding characteristics.

Like what?

Cheap stuff.

It's a very important element.

Thin as you can.

Would you buy a thick condom if you tried it on a man?

When it is worn, it is not tight.

I wouldn't buy it again if I was unusually oppressed!

Just don't loosen it.

Leaks can interfere with the most important functions, and it's a hassle to start and end them.

Good maneuverability.

You're not applying gel or oil, are you?

It's fun to use.

Sometimes you buy colorful guys with your eyes on them, right?

I can't smell it.

I think it's a lot for women, but many people don't like the smell specific to rubber.

Easy-to-handle packaging and design.

Wouldn't it be surprisingly important?

Condoms, in polar terms, are bags of rubber.

Still, that's all I have to figure out.

There may be more.

It is only when there is demand that diverse products compete in the world by shredding their riches.

Otherwise, is there such a wide variety of condoms in the world?

Demand is too diverse, condoms.

I seriously think so.

What are you trying to say?

It's dangerous to make it and then think about its uses.

It's made to fit the purpose.

Management without management policy.

Product development without product planning.

Dipelopments without research.

R&D without demanding characteristics.

Then it's a muzzle.

Without a sense of purpose.

It's rubbery, repulsive, and it lasts about as long as a tire, right?

I don't know if I can even make it comically.

It's already in the world.

But you can't beat the competition, can you?

It would be a huge loss if other players who are thinking about using natural rubber in this game optimized first, right?

Let's get back to condoms.

It's a demanding characteristic, but is it possible to meet everything perfectly?

No.

Some things you don't get unless you sacrifice something somewhere.

Thickness, for example.

Thinner than that?

How far can you go?

It seems to be too thin and can be torn when used. It is the end of the line.

Somewhere we have to compromise.

When it comes to giving it thin and strong, what about using carbon black with reinforcing agents?

Now the stretch is sacrificed.

To some extent, it will be possible to stretch, and it will be able to be worn.

But there is a good chance that the tightening will be intense and no longer a place for sexual intercourse.

You want to use a condom with a tire odor in the first place?

I can't do it.

How about the smell, for example?

How to reduce the smell while using natural rubber?

There is.

It is only natural that impurities to be mixed during the sap phase should be removed whenever possible.

We should give up sulphurisation on the sulphur system.

It should be a sulfurization system using peroxide, peroxide sulfurization.

I think the formula is top secret for all manufacturing companies, but this is a lot when using natural rubber.

But this doesn't make it omnipresent either.

Tensile strength is inferior to sulphur addition.

The condom itself will be thickened to retain the same strength.

Still doesn't eliminate the smell of natural rubber.

There are distant guests.

How to solve two examples simultaneously?

There is.

You can give up natural rubber and use polyurethane.

All sorts of technical challenges solve all at once.

There is also a problem with this.

It's expensive.

A grand tour that goes on and on.

And different types of products line up on shelves.

A product that sells prices.

A product that sells designs.

A product that sells features.

Aims vary, but they can be common in thinking.

Differentiation.

If you return the back, you can call it habitat separation.

If there is demand, the product survives by beating the competition.

Only disappear if demand disappears.

"If you're just going to make a chunk of vulcanized rubber, you can. But it doesn't matter if you're satisfied with your performance."

"What properties does rubber have to be adjusted or designed to be used as a shield?

"Yeah."

Sakura is quick to understand and helpful.

Easy to talk to.

"Let's start by making a sheet as a sample."

"Sample, right"

"Yes, change some of the formula conditions to make a sheet of vulcanized rubber. You just need to grasp the characteristics because you can feel it."

"Formulation terms, is it?

"Lespy."

"Recipe?"

Ahhh.

My knowledge is biased, isn't it?

When I was taught the rubber formula, it pissed me off when I said the recipe.

You can't get out of it.

"You can go with the recipe for the dish. Because it's the ratio of the formula when the polymer is 100."

"Polymer?"

"In this case, it's about the resin content of natural rubber."

I omitted the explanation here.

I guess I shouldn't really.

A polymer is a polymer of monomers.

You can think of monomers as the smallest units of the molecular chain.

What's with the formula?

Just carbon black and sulfur?

There is no sulfurization accelerator.

There are no sulfurization aids.

There is no anti-aging agent.

If you're going to apply your hand, do you want to add some oil to help with the workability?

Do you want to replace the natural wax content with an anti-aging agent?

That's all I can think of.

Synthetic rubber?

Exactly, no.

Honestly, it's not enough.

But there's no choice here.

It doesn't make sense where I've tried to ask for something I don't have.

You should do something with the ingredients in your hand.

"Time is free until this evening. I'll help you out a little. I'm interested."

"" Please!

I'm surprised they all rolled together!

Muto asked me a question when I was helping filter natural rubber latex.

Well, I expected it.

Because he is a merchant.

"Do you think you can make tires?

"Oh, I knew I was after you"

Well, you'd be interested.

But it takes time to explain.

The problem is that the tires are visible and the hybrid construction is made of a variety of members.

It's hard to reproduce that as it is.

alternatives, or whether they can be reproduced by fulfilling the tyre dawn substitute.

"Could it be a little longer? Can I talk to you later?

"Okay."

Tires.

Tires are composed of a variety of members.

Yes, it looks like a chunk of rubber, but it's a fine composite.

Materials have a variety of properties, and their advantages can be exploited to a greater extent by multiplexing.

It also compensates for the weakness of the material.

Even carbon fiber can be cut by human hands without tools.

Tensile strength makes it easy to cut strong carbon fiber at the hands of people if you make knots and pull them.

Extremely vulnerable to shear stress.

They transform those weaknesses into tough members because they are reinforced with resin after multilayering carbon fibers.

You can make it up to me with something.

Something came down on me.

Isn't there a substitute for all sorts of materials you can make right now?

"Solidification of the sap proceeds with the reaction if acid is put in. Conversely, if you make it alkaline, the preservation will work to some extent"

"Yes."

"You should dry the raw rubber sheet as much as you can on that. In about a week."

"Okay."

Although it is a hardened natural rubber resin.

White at first.

As it dries, it becomes the colour of the wheel rubber.

More time will pass and it will transform into a dark brown.

This natural rubber has several strengths and weaknesses.

What are your strengths?

Rubber-like elasticity, high mechanical strength and good elasticity.

The price is very low compared to its physical properties.

Weaknesses?

Weak with heat, oil, weather and ozone resistance.

Aging is easy on the surface.

so that the old wheel rubber runs out.

Priority will be given to shaping it for the moment, but you want wax.

Wax?

Can't we use beeswax?

Well, you should try adding that to the test.

Then weigh.

What's the recipe?

It's appropriate.

Better than not.

Raw rubber is 1 kg.

Does Sakura have a pharmacist's eye mass?

I thought so, but I wasn't worried.

They have new making skills in the top positions of alchemists.

Weight measurement.

I want it too, that.

Carbon black is a substitute for burning candles.

That amount is 150 grams.

Appropriate.

This carbon black, perhaps, but its particle size is small.

I'm somewhat worried that it will spread evenly with practice.

Well, we just have to try it here.

And sulfur.

It was obtained in the volcanic zone and has not been refined.

Sort of.

In the real world, it's made from hydrogen sulphide, a by-product of oil refining.

I can't help it.

This time, it's the amount of sulfur that shakes the conditions.

The sulphur quality obtained is also not necessarily constant, but when I say it, there is no limit.

First, we need to determine the sulfur ratio, which is a sulfurizer, right?

The sulphur quantity is 5 conditions: 20, 40, 60, 80 and 100 grams.

This is also appropriate because it is the first.

The next thing I know, it's mixing, that is, practicing.

Roll mixing?

It's a large pastama scene, no matter how you look at it.

"Did you make this on purpose?

"Be confident, actually"

Kono, the blacksmith, you're so forceful!

Exactly. I wouldn't be able to get a Banbury mixer though.

The pride seems to be on the machining accuracy of the bearing bearings.

But.

What do you mean, turn it around manually?

Kono, it's sweaty.

Summon Jericho by returning Helix.

I don't know about tiredness, so I guess I'll be a good fit.

Okay, then.

It's vegetarian.

What's vegetarian?

It's just raw rubber, no formula or anything, and it's a task to use the roll to work it out.

By being refined, natural rubber starts to emit heat and also decreases viscosity.

If you do this first, the formulation is easy to mix.

Cut and roll with a peeling knife from the left and right of the rubber sheet wrapped around one roll.

And put it between the rolls.

This was shown repeatedly every five alternating times, left and right.

It is commonly referred to as cutting back work.

"This is how we work."

"That's brilliant."

"Then let's all try it."

"Huh?"

Speaking of what do you do 5 terms for?

It also included a hands-on experience.

So here we go:

Let's mix the formula.

And make it into sheets.

The thinnest mold is 3 mm.

Let's go for a slightly thicker sheet thickness than that.

But I have a caveat.

Sulphur, which is a sulfurizing agent, should not be added from the outset.

The mixing of carbon black takes some time.

Besides, when mixed with carbon black, heat also occurs there.

Long thermal history can cause sulfurization to proceed on its own.

I can cook vulgarly, too.

Let's start with carbon black.

Practice while putting carbon black between the rolls in several portions.

Occasionally but carbon black dust flies.

Because it is sealed when it is a banbury mixer, the impact of this will be minimal.

This is why the refinery gets dirty.

When carbon black is worked in, it becomes like the black rubber used for tyres.

Well.

Sulphur input here.

Hurry, hurry!

The mixing ends when the cutting back operation is completed.

We all took out the seat while helping and disconnected it to follow the mold's shape.

Now you'll be ready to add sulfur.

But.

That's only the first condition.

The other four conditions were Kono, Sakura, Muto and Lucan, and they did each.

I helped a little along the way though.

Well, I'll be good at this after a few exercises too!

I'm not worried.

And it's sulfurization.

Two plates heated to 150 degrees with excess heat.

The mold in between is also warmed by excess heat.

The unsulfurized sheet cut in the mold is filled and superimposed between the plates to add sulfur.

Time is 20 minutes.

Well, this is also appropriate.

It's a slightly thicker sheet, so I only have a little longer time.

Come on.

All you have to do is wait to bake it up.

It may sound like bread, but it's sort of similar.

"So, the question is, is it possible to manufacture tires?

"Yeah, what do you say?

"Honestly, I wonder if airborne tires are difficult"

"I knew it."

Definitely will if it is a modern tire.

Even rubber alone is different from treads, sidewalls and tubes in polymers and formulations.

The carcass portion that constitutes the skeleton of the tyre.

Tire cords made of fibers such as polyester, nylon, and rayon are laminated here.

A belt that serves as a reinforcing layer between the tread portion and the curcus.

Steel cords are used.

Beadwire embedded in the part that fits the wheel.

It also helps to suppress both ends of the kirkus.

The fiber part used to be made of cotton.

Fever and adhesion become problems.

In addition, both steel cords and wires are plated on their surfaces and glued by sulfurization.

Yes, adhesion technology is also important.

It seems more likely that a chunk of vulcanized rubber is like a tire for a forklift.

The first sample sheet was ready in about 2 hours.

What do you think?

Sheets of 20 grams of sulphur, 40 grams of sheets and 60 grams of sheets are in turn hard rubber.

JIS, bring the hardness gauge!

You won't know until you can quantify it!

But if you believe the feeling of pushing with your fingers, you're sure.

60 grams is harder.

How about 60, 80 or 100 grams?

Hardness hasn't changed that much.

Too much sulfur doesn't mean there can be a massive cross-linking reaction.

I guess the amount of sulphur is fine with 60 grams.

If I multiply this amount by about 10 times, it will be Ebonite, well, okay?

"The surface is nicely made."

"Could this seat be used to reinforce armor or something?

Sakura-san is the only one with Shagu.

What, right?

"A little more, how do you make it hard?

"Naturally, you should increase the amount of carbon-black formula. Shake a few conditions and create a sheet as well."

"Yes!"

"Each process should be remembered for work. Shorter reproductions will be available."

"Right."

I'll take care of it later.

I'm very concerned about something right now.

An idea was floating around.

New weapon, you think you can make it?

I received your friend registration application from Sakura.

Let me know when you have a good rubber product, okay?
