Duan Tongshan didn't take into account that his factory's products still have so many shortcomings, but at this moment, Li Jian reminded him that there were so many obvious shortcomings, Duan Tongshan also fell into contemplation, the goal of the upper level is export, and according to the previous export experience, even if the domestic first-class products are sold, foreigners will pick and choose and find out all kinds of faults, not to mention that these seem to be in accordance with strict standards, in China is the second-class level of telephones.

"What do these shortcomings have to do with these ponds?"

Duan Tongshan couldn't think of a solution to these difficulties, so he had to ask a question that seemed easier to explain, what was the use of these ponds.

"Dig, all dug through, ten meters deep, one hundred and fifty meters wide, three hundred meters long big pit, after being treated with waterproof materials, the interior is designed according to this......

Li Jian continued to use the small wooden stick on the ground to start the gesture, which made him feel that he needed to prepare a blackboard with him, after all, the things drawn by the small wooden stick were not very clear in the gray-yellow soil.

"This is a sedimentation tank, and we are not engaged in chemical industry, what do you want to do with this?"

Although Duan Tongshan has never engaged in chemical industry, he still knows some basic common sense, such as the sedimentation tank in front of him, which is useful in many chemical companies, so he can see it at a glance.

"Since you know, then I don't have to paint so fine, I'm going to make my own plastic, the plastic we are using now is polyethylene, and it is high-density polyethylene, the production process is simple, the cost is relatively low, but our petrochemical plant, the catalyst is not suitable, the residual sulfur is more, affecting the molecular structure, resulting in easy aging, poor mechanical resistance, poor gloss, in fact, if we make our own, we can solve this problem, so that our telephone material, look more high-end."

Li Jian wrote a few more English letters, pe, pc, abs...... and so on are the names of the plastic industry, but Duan Tongshan didn't understand it, and he was still digesting the meaning of Li Jian's words.

It's not a joke to make your own chemical products, a tape recorder factory, running to make chemical products, and it was in China in 1985, all kinds of chemical raw materials were in short supply, and leaders at all levels had to exchange their pants for dollars and ethylene back, even if you could do it yourself, you had to have someone to provide raw materials.

In the entire Jiangzhou City, all the chemical raw materials that can be mastered are supplied to those large enterprises, where is there any spare strength to give Li Jian, a Qianghua technology, a blind toss.

"But as for raw materials, we don't have a petrochemical plant that we are familiar with, and now ethylene is in such a short supply, we can't import it without foreign exchange."

Duan Tongshan is a qualified factory leader, thinking about problems always from the overall situation, Li Jian nodded, he admires Duan Tongshan is this, so he doesn't hide it, and Duan Tongshan needs to help deal with the future work.

"I am ready to produce my own raw materials, that is, ethylene, if the process is not mature, we will first produce vinyl alcohol, use polyvinyl alcohol to exchange ethylene with foreign countries, if the conditions are ripe in the future, we can also use polycarbonate instead, as well as ABS."

Li Jian drew a piece on the ground, so that Duan Tongshan could see that it was the location of the entire tidal flat area plus a cement factory.

"I moved the paper mill over, these sedimentation tanks are used for reclaimed water treatment and black water treatment, the cellulose and lignin in the black water, after chemical treatment, can make alcohol, alcohol can make ethylene, can also make polyvinyl alcohol, but the cost of making ethylene is too large, than the cost of coal manufacturing or oil manufacturing, so we use it to make polyvinyl alcohol, sell it to the domestic use is small, we directly use barter, exchange ethylene back."

Duan Tongshan was stunned for a long time,

"Li Jian, you're not kidding, you can use something other than coal and oil to produce ethylene? It's not laboratory production, it's industrial production, are you sure, do you know what impact such technology has on our country? Our country has saved at least a few hundred million dollars in foreign exchange. ”

Li Jian nodded,

"I don't plan to hide this technology for personal use, but can give it to the state for paid use."

Duan Tongshan noticed the word paid in Li Jian's words,

"How do I get paid?"

"In terms of means of production, we are inclined to Qianghua Technology, what we want to use, they will provide us with something, otherwise, I will charge a user fee of 100 yuan according to the production of one kilogram, and it is estimated that the factories under the Ministry of Petroleum and the Ministry of Coal should be able to afford it."

"They must choose the means of production, we are a private factory, how many materials can be used, they are not stupid, but this patent, when you go to apply for it, no one should know about it, right? By the way, Li Jian, I have to ask you, where did you learn these things, I see that you are so busy every day that you don't have time to do research. ”

Duan Tongshan finally couldn't help it, he didn't believe that Li Jian's knowledge was seen from any notebook, such a level of technology was no longer something that could be accommodated in the current era, unless, it was the enemy's infiltration!!

"The owner of the notebook should be an old professor in Huaqing, who used to do research in a Berkeley laboratory, but he didn't expect to return to China with the results, but he was thrown into our broken cowshed, so let me pick it up, but I will have so much, or what do you think I have to do with Huaqing, where are there many talents, maybe I will meet another old professor like this."

Li Jian prevaricated, looked at Li Hongjun with a blank face, and explained to his father,

"Dad, don't worry, your factory will not suffer a loss when you move over, all the reclaimed water and black water strengthening technology will be bought with money, your paper mill is equal to less sewage treatment costs, and if you want to expand your production capacity in the future, you can expand it to as big as you want, what are you worried about, and this Qianghua Technology is hanging your name Okay, inside and out, you put the money in your left hand and in your right hand."

Li Hongjun shook his head,

"I'm not worried about this, but I think that you have come up with so many advanced things, the country can let you be so free, your mother and I are both farmers, even if we later entered the factory, but we are also ordinary workers, will they feel more comfortable with another person mastering these things, otherwise, you better not take it out."

Duan Tongshan looked at Li Hongjun, and had to admit that Li Hongjun was right, if it was his son, then he would have to dissuade him, after all, at present, among the leaders of state-owned enterprises, there are many people who do not consider the interests of all employees like him, not to mention, even if they consider the interests of employees, they also consider the employees of their own units, they will definitely feel that such advanced technology is safer in their own hands, and they can save money.
