The villain of rebirth wants to divorce

Chapter 725

"Master, is this resin a SPA?" Xuan Xiao checked everything a few times, pointing out the question he didn't understand the most.

"It is a kind of superabsorbent resin. It has the function of absorbing water hundreds to thousands of times heavier than itself, and has excellent water retention performance. Once it absorbs water and swells into a hydrogel, it is difficult to separate the water even if it is pressurized. come out."

"Miraculous, similar to cotton, but not cotton, right?"

"Yes, but it's more powerful. It's a chemical substance. It's more difficult to make. If we want to make money from it in the future, we must master the core technology. This SPA is its name, and this technology cannot be spread outside."

Xuan Xiao nodded.

"But how to make it?" Xuan Xiao looked at Lin Wushuang curiously.

Lin Wushuang looked at Ni Zhiyun and Yue Ran who looked at her in unison, expressing that they were very useful, and he was still the smartest. Sure enough, science is power.

"Come on, let's go to the kitchen." Lin Wushuang waved his hand mysteriously, although the others wondered why they were going to the kitchen.

Lin Wushuang first showed them the principle in a simple way.

"I see"

"There are a few things that need to be done separately, these are all crafts, and many chemical engineering formulas are waiting for me to write to you"

Production raw materials acrylic acid (content >99.5%), sodium hydroxide solution (content 30%), N,N'-methylenebisacrylamide (content 99%), ammonium persulfate/sodium sulfite (content 99%) are industrial products, and so on.

Seeing the headache, Ni Zhiyun decisively pulled Yue Ran, who was even more confused than him, to express that they needed to be quiet.

"I'll tell you about the ratio and raw materials in detail later, and the temperature and so on are indispensable. This is a big project." Lin Wushuang felt that he had said so much in one breath, no matter how smart his apprentice was, he would He looks dumbfounded, after all, he has never learned chemical equations.

"Master, are these all the knowledge you learned in your previous life?"

"Yes, it's great"

"Great, but it seems like I've never heard of it"

"A civilization that may not exist in this world." Lin Wushuang also felt a little strange, this world did not seem to have the civilization of her original world.

"Master, I think I should learn from the beginning. Um, I don't understand this chemical equation." Xuan Xiao is Xuan Xiao, whether he knows it or not, but he has a strong thirst for knowledge.

Alas, the apprentice is too good, I guess he will learn it soon, and he is a proper student master over there, don't you want to be a god?
Lin Wushuang copied a few chemistry books for Xuan Xiao based on his memory, and asked him to study by himself, and waited to see how he did it.

Xuan Xiao studied day and night, and sometimes he even learned experiments based on Lin Wushuang's pictures. Of course, sometimes he failed. Chemistry failure is very scary, but Xuan Xiao has the indestructible body of King Kong, so it's okay.

This made Lin Wushuang, who gnawed on chemistry in the previous life, very envious. This guy is a genius among geniuses.

One month later, Lin Wushuang got the first batch of resin that Xuan Xiao made for him, which was only as big as a small bowl.

"Master has done it!"

"Amazing!" Lin Wushuang looked at those small white powders that were not easy in size, and felt that he was really lucky.

"Since you know everything, then we must strictly check the selection of candidates in the future, because once the core technology is lost, it will be fatal."

"Master, don't worry, I know." Xuan Xiao was very happy to be approved by Lin Wushuang.

"Master." Xuan Xiao looked at Lin Wushuang a little shyly.

"Why, do you still want a reward?"
