A small inland steamer coming from Zhenhai Port slowly docked at the Yong'an Port Wharf. With the assistance of steam booms, the laborers on the wharf were quickly unloading a lot of packaged goods. Next to them, seven or eight heavy-load carriages had been impatient. The coachmen took the bill of lading and directly grabbed some of the cargo rubber and **** they needed, and then drove the carriage and drove towards a factory not far away.

The factory covers a considerable area, with spacious and bright brick and tile factories built on most of the land. At this time, in this company named "Yong'an Rubber Products Factory" (the Ministry of Industry and Commerce holds 70% of the shares, the East Coast Company holds 20% of the shares, and the New China Development Team holds 10% of the shares), many workers are sitting in front of the workbench and busy carefully.

They were dealing with raw film with a focused expression, and the source of raw film was Xinhuaxia Island. Since the East Coast people planted more than 3,000 rubber tree seedlings in the mountains near Xinhua Port many years ago, the survival rate of rubber trees was not high due to climate, environment and poor care. Later, they had no choice but to change places to transplant. Until now, there have been less than 800 rubber trees near Xinhua Port growing one after another, and it was the rubber cutting period.

The mucus secreted by certain cells in the inner layer of the rubber tree bark is the raw material for "latex" needed by people from the East Coast. Local collectors took out knives or axes to cut a hole in the bark, and then the liquid flowing out of the cut can be collected into a container fixed on the tree. The collected liquid cannot be directly used and must be appropriately diluted, then added acetic acid to make gel, and finally a heating and smoke process can be used to make initial use.

People in the East Coast knew nothing about these processing techniques at the beginning because no one understood this knowledge. They also gradually found some methods of processing rubber through continuous exploration and practice over the years. For example, analyzing the ingredients in the liquid flowing out of the rubber tree, such as how to deal with impurities in the latex, such as how to make raw rubber, etc. Among them, making raw rubber is the most critical process.

The producer usually takes out a stick covered with a layer of white latex from the small bucket where the latex is placed, and then puts the stick on the brazier and smokes it repeatedly to make it dry. Then puts the stick into the small bucket, continues to apply a layer of latex on its surface, and then smokes it dry. This is repeated many times until a large piece of white glue-like substance is accumulated on the stick, then cut it off, place it aside, and collect it by a special person.

At this time, the substance they get is raw glue. Of course, sometimes they will use a process, that is, repeatedly crush the gel with a roller to remove the whey inside, and then obtain film with a thickness of several millimeters, which is also a valuable intermediate product.

As for how to use rubber, the East Coast people have done a lot of research over the years. After all, this is a substance that is widely used in later generations. They are forbidden to pay attention to the first-hand information on the use of rubber by the East Coast people comes from the Mameluko ​​people in Brazil. These slave hunters often go deep into the Amazon River Basin to capture natives, so they are also fortunate to see how natives use rubber.

The Indians living in the jungle discovered the various uses of rubber early on. They knew how to make rougher films and then use them to make rain boots. They also found that latex is waterproof, which is an amazing function in the rainy Amazon basin. The East Coast people have opened their minds based on this and believe that latex can be applied to canvas or clothes to make it waterproof. The Indians also made many rubber containers using clay molds, which is another wonderful use. Of course, the greatest discovery of the Indians was that they realized that the latex had a leather-like appearance after being smoked, and could make many useful things.

In short, the Indians developed many rubber uses and processing methods over the long years. After trying every means to summarize this information, the East Coast people began to design their own processing technology, preparing to apply this magical natural gift rubber on a large scale before the Europeans could react.

However, perhaps the East Coast people were too optimistic. In fact, as early as 1615, the Spanish began to use rubber to make soldiers' rainproof cloaks. Unfortunately, the Spanish did not deeply realize the other uses of this thing. It was not until more than a hundred years later, in 1736, a French expedition team to Peru gradually developed various uses after researching rubber, and eventually became popular all over the world. It can be said that the French developed the great material such as rubber, of course, this honor now seems to be obtained by the East Coast people.

The rubber products factory, now established in Yong'an Port, has undertaken the important task of researching and developing the usage of rubber. Although it has only been more than two months since its establishment, they have initially developed several gadgets based on some of the experimental records handed over to them by the Institute of Natural Sciences. The first one is the eraser. They found that the rubber blocks can erase the pencil handwriting on the paper, which made the drawing technicians on the East Coast overjoyed. They no longer had to re-draw one because of a small mistake in the drawing, which saved them a lot of trouble.

The second use is much more meaningful than rubber, because the technicians of the technical department of Yong'an Rubber Products Factory imitated the ideas of the Indians and Spaniards and made many waterproof equipment, such as waterproof leather goods, tarps (cotton, linen, tweed cloth, etc.). However, they do not directly apply natural latex to cloth like the Spanish or Indians. They do not have this condition because it requires direct processing at the place of origin, but basically all those shipped from New China are rubber blocks (natural latex can easily condense into blocks), and rubber blocks are obviously not directly applied to any object, because you need to soften them first.

However, this obviously cannot stump the East Coast technicians who have already opened up their brains. They tried all the chemicals they could find over and over again, such as tar (benzene in coal tar can dissolve rubber), sulfuric acid, hydrochloric acid, soda ash, caustic soda, etc. Finally, they found that **** (produced by the Northern Chemical Factory, currently mainly used in refrigerant and medical anesthesia in the East Coast) are good solvents for raw rubber blocks. The dissolved and softened rubber has very good viscosity and can be blended into various sols, and then it is evenly applied to leather or cloth materials such as materials by artificial brushes. After it is dried, it will be a good waterproof material. Finally, we no longer need to wear low-yield, expensive and relatively bulky whale skin waterproof products.

Later, some people suggested that this sol-coated tarp can be used to make balloons. This idea even attracted the interest of several travelers and invested heavily. The project has officially started. I believe that further news will be heard in a while.

In addition, the factory also cooperated with three companies, including Dayuhe Machinery Textile Factory, Ping'an Weaving Factory, Luoqia Textile Factory, etc., to output fixed-specification raw films to them. Then these companies stick the films to the fabric (the dissolved raw glue has very good stickiness) and make them into various textiles such as slings, elastic pants, etc. At present, these products are also in the experimental stage, but judging from the responses of some local trial customers in the East Coast, the market has a high acceptance of these textiles and the sales prospects should be quite good. In the future, it will definitely become another pearl in the East Coast textile series.

With slings and elastic pants, under the divergent thinking of technicians, various other rubber products have been developed one by one. There are only ones you can't imagine, and there are no ones they can't do, such as inflatable beds, swimming rings, air pillows, air cushions, etc. The production method is quite simple. Just immerse the inner core of these items in the sol made of dissolved rubber. In addition, useful small things such as hoses, rubber wires, tapes, and elastic bandages have been gradually designed by everyone. The next step is to try production to see how the effect is used and whether it can be used.

Of course, from the above statement, we can also see that all rubber products on the East Coast currently use raw rubber, that is, rubber that has not been vulcanized. Although items made of this rubber are quite good in terms of viscosity, elasticity and elasticity, if placed in a low temperature environment for a long time, the rubber will slowly harden and lose its elasticity, which is fatal to this kind of product. Because this means that in the cold winter, rubber products will have a high chance of losing their effectiveness.

In addition, the raw rubber dissolved by solvent will easily decompose and lose its effectiveness when it encounters hot weather. It can be said that if these two defects are not solved, the sales of rubber products on the east coast and even the whole world will encounter many limitations, which will eventually affect the development of this sunrise industry.

Especially in the cold South Patagonia and the hot New China region, do you still expect this kind of thing to be sold at a price? No sensible person would buy such a thing that can only be used in summer and autumn. What? You said that the rain boots made of whale skin are bulky? Well, maybe it is very bulky and expensive, but this rain boots will not have any problems in extreme low temperatures, and the insulation performance is also good. This is a big advantage, isn't it?

To solve this problem, you may only think of ways to deal with rubber. No matter how ignorant or ignorant the time travelers are, at least some people have heard of the term "vulcanized rubber". However, the specific vulcanization and the specific process are all the same. There is no way, but Yong'an Rubber Products Factory has to find a solution on its own. At least they already know a general direction, which is to use sulfur to react with rubber. As for whether it is burned, heated, or dissolved, it has to rely on themselves to do more experiments. There is no other shortcut to take, so they can only try step by step and eliminate them one by one.
