Since he had made up his mind about the planting, Li Tianyang added another 1,000 indigenous captives to Jingpu Port to help, and then he threw it to Wu Chao, the person in charge of Jingpu Port, and he took care of all this.

The three boxes of natural rubber that were given to Li Tianyang as a gift along with the rubber tree species were handed over by Li Tianyang to the Chengcai Research and Development Institute, and they did some research in advance.

Li Tianyang put this natural rubber in his official residence, and took it out to play with when he had nothing to do, firstly, he naturally had many expectations for it, and secondly, he was a little surprised by the characteristics of this natural rubber.

The reason for the surprise was that Li Tianyang found that the properties of this natural rubber seemed to be very different from the rubber products he had used in later generations.

For example, in the case of high room temperature, in addition to the elasticity and elasticity of these rubber balls as Li Tianyang knows, they are easy to soften, sticky, and then stick together, if they are produced as raw materials, I am afraid they will not be able to be used for too long.

This one shortcoming alone completely obscures several other advantages, and it is no wonder that Westerners, who are good at discovering and exploiting new things, dismiss these things!

However, since later generations can use these rubber raw materials to produce various pieces of products, Li Tianyang is convinced that as long as he can persevere, he may not be able to find a way to change these shortcomings.

Moreover, now this natural rubber is not unusable, at this time the chicken coop port is just entering the rainy season in winter, the most humid is not enough, Li Tianyang every time he goes out to go outside for a circle, unless he is wearing leather boots, otherwise the cloth shoes will inevitably be soaked, and the feet are rare and refreshing.

Not to mention that Hongmen has to be the children of ordinary people, without such conditions as Li Tianyang, although the Hongmen team is quite rich, they don't dare to spend more than a pair of silver dollars to wear under their feet, and these leather boots can't be often wet, otherwise they are easy to corrode.

Before handing over the natural rubber balls to Chengcai, Li Tianyang first found someone to take out a small part of the rubber balls, and according to the shoe sample system, made a few pairs of rubber shoes into a mold, and then laid the insoles and other things inside, and wore them out to be called a refreshing and neat!

Of course, such a good thing, Li Tianyang naturally did not forget to get a few pairs for his family, anyway, this is a gift from the Portuguese to himself, it cannot be completely regarded as public property, he is close to the water and the building is the first month, and it is not a violation to facilitate his relatives!

It's a pity that these beige rubber shoes, the sole is still too soft, even if the cushion is covered with a harder insoles, walking on the road by raised stones and the like, it still makes the soles of the feet hurt, and this style, not to mention, even if it is an ordinary person, there are only two words: ugly!

Fortunately, Li Tianyang doesn't care about this, he cares more about the performance of the rubber, whether it can be waterproof, and how long it can be used.

Here Li Tianyang is trying on his new shoes, and they are full of interest in this natural rubber, and they quickly test out many characteristics of this rubber.

For example, in the case of a large temperature difference, the two contrasting characteristics of this rubber make it an inevitable shortcoming in the use of daily life.

R&D personnel are like that, the more novel and strange things are, the more they can arouse everyone's interest in this thing, and the more they want to figure out the principle of this thing, and use its characteristics to develop a variety of more novel products.

In addition, they began to study how to improve the sticky and soft defects of natural rubber, making it more suitable for daily use, able to use for a longer life, and so on.

However, research and development is a long and arduous task, especially in ancient times when the basic principles of chemistry were not even clear.

With the clear number of raw materials in the Hongmen team, Li Tianyang is very worried that this rubber tree has grown into a mature tree, and I am afraid that it may not be able to make progress!

For this reason, Li Tianyang quietly took out his notebook when he was a child, flipped through the knowledge recorded on it from later generations, and at the same time racked his brains to recall things that had been related to this rubber.

Not to mention, it really made Li Tianyang think of something, but whether this thing is suitable for this rubber or not, then Li Tianyang is not sure at all, and it is just one word - vulcanization.

As for what is called vulcanization, the process steps of vulcanization, and what is the process principle, Li Tianyang is a master of nine out of ten tricks - he doesn't know anything, but since he has a sulfur word, it may mean that this requires the use of sulfur as a raw material?

Li Tianyang didn't have the slightest certainty, he told Chengcai what he had gained, and explained in advance that this was just a suggestion, so that Chengcai and they didn't have too many expectations.

However, Li Tianyang himself didn't expect that his on-demand broadcast would be such an important help to their R&D institute.

It was Li Tianyang's seemingly casual suggestion that made the rubber R&D team specially composed of the R&D Institute make an important breakthrough in a short period of time and avoid countless detours.

For newly produced rubber products, according to the proportion of sulfur, the more sulfur is added, the color of the product will be darker and brighter, and the less will be close to the natural color; And the darker and brighter the rubber products, when they are handed over to Li Tianyang, the more similar they are to the rubber products used by Li Tianyang in later generations, and they can even be said to be basically the same.

The softness and stickiness of natural rubber at room temperature are gone, and the rubber obtained after vulcanization has no fatal defects in the case of perfectly maintaining the elasticity of natural rubber.

Li Tianyang held a pair of tall rubber boots made of vulcanized rubber, and felt infinitely emotionally in his heart that he was taking a big step forward on the road of industrialization in the future.

After testing the vulcanized rubber, Li Tianyang was satisfied with the pair of high rubber shoes specially made according to his feet and left, but before leaving, he was very surprised to find that as long as he came by himself, he would always show off to himself the success of various R&D institute products but there was no trace, and he was always received by the members of the rubber R&D team.

Even according to Chengcai's character, he should like the most interesting raw material analysis and research like rubber, but from beginning to end, Chengcai has not participated in the research and development of vulcanized rubber, and the whole person doesn't know where to go.

Li Tianyang shook his head, leaving behind a little bit of peace in his heart, his brother-in-law is a research maniac, although he doesn't know what he is doing, but Li Tianyang believes that he must be hiding somewhere to conduct research.
