Chapter 192 Don't Take It As A Joke

Chemical cleaning is nothing more than the use of solvents, strong alkalis and surfactants to achieve decontamination.Solvents used for chemical cleaning generally have certain toxicity and will cause secondary pollution.Alkalis can cause corrosion to the cleaning material and damage the user's skin.Surfactants do not have these defects, but their detergency is not as good as solvents and strong alkalis.

In order to obtain the best decontamination effect and reduce secondary pollution, it is necessary to properly coordinate these three substances, thus forming different cleaning agent formulations.

Surfactants themselves are also a very large family, common compounds such as sodium alkylbenzene sulfonate, sodium fatty alcohol polyoxyethylene ether sulfate, fatty alcohol amides, and lauric acid diethanolamide.

The development of chemical cleaning agents is basically to do two things, one is to explore new compounds, especially new surfactants, and the other is to explore new formulas, that is, to change the proportion of various substances in the cleaning agent. Detergency, corrosion, stability and other aspects are compared to select the optimal ratio.

Gao Fan naturally knew the ingredients of some new surfactants, but with his current conditions, he could not establish a synthetic process to produce those new surfactants, so the chemical cleaning agents he developed were mainly based on the existing ingredients. Adjust the formula accordingly.

Cleaning agent manufacturers all over the world are doing the same work, but because of the limitation of thinking, no one can come up with a better formula than Gaofan, so the cleaning agent he launched was an instant hit in the Japanese market.

Gao Fan in the previous life was known as a humanoid self-propelled database, but the biological media storage of information is not as accurate as the physical media storage. Regarding the formula of the cleaning agent, he only remembered some key links, and the details were a little bit wrong.

He sent the formula of the cleaning agent to Yang Kai, with the intention of asking Yang Kai to help check whether it was similar to foreign products.After Yang Kai searched the information and confirmed that Gao Fan's formula was original, he began to ponder the mystery of this formula.

The decontamination principles of various surfactants are common sense to those who study chemistry.However, what kind of effects will occur when different surfactants are combined together is more complicated. It is not enough to rely on imagination alone, and it needs to be verified by experiments.

Inspired by Gao Fan, Yang Kai positioned his future research direction on computational chemistry, so he started from this perspective when considering problems.He made some calculation programs to analyze the interaction mechanism of various surfactants. At this time, Gao Fantuo Bei Dao Zhengshen bought the computer and sent it to Peking University. Yang Kai took this subject as a practice tool for his computer learning.As a result, he really discovered the shortcomings in the formula provided by Gao Fan.

"You see, this is the equation of the interaction parameters between the surfactant adsorption layer and the multi-component molecules in the micelle. By adjusting the ratio of different components, different βS and βM values ​​can be obtained.

"I used different proportions to calculate and obtained the curves of interfacial tension of different formulations. It can be seen from the curves that the formulation you are currently using is not the best point. If the ratio of non-ionic active agent to anionic active agent is reduced a little bit, it can Get a better decontamination effect."

Yang Kai took out a few pictures and introduced them to Gao Fan, pointing to the curves on them.

"Did you draw these points?" Gao Fan looked at the graph with some emotion.

For future generations, as long as such a calculation is thrown into Matlab, a beautiful graph can be generated in minutes, but what Yang Kai showed him was a completely hand-drawn graph.

Gao Fan could imagine that the above points were all drawn by Yang Kai using the computer to measure the coordinates one by one on the coordinate system.With so many dots, thanks to Yang Kai's patience to draw.

"It took a lot of time to calculate these results, right?" Gao Fan asked.

Yang Kai nodded: "It takes at least half an hour to calculate an equation. Sometimes I set an alarm clock, and the computer calculates over there. I go to bed first, and wake up in half an hour to see the result."

"Brother, you have worked hard." Gao Fan said.

Yang Kai said with a smile: "It's hard work, this is something that I enjoy. Actually, I have already made some judgments before the calculation. Seeing that the calculation results match my judgment, I feel that I can't explain it."

"I'll send these new formulas back immediately, and let the factory do experiments to verify them." Gao Fan said.

After all, he added with a smile: "If these formulas are indeed better than the original formula, we will treat them as an enhanced version and sell them at a 20% price increase. The extra profit will be divided into half."

"Only half?" Yang Kai said subconsciously, and felt something was wrong when he finished speaking, he quickly waved his hands and said, "Don't stop, I'm talking nonsense.

"Good guy, I just remembered that this is a big deal of 100 million yuan for one order. The price will increase by 20%, and I will share half of it. Wouldn't it be 10 yuan?"

"Is there so much?" Gao Fan was also taken aback, and thought for a while, isn't it 10, he seems to be too generous.

Of course, there is a cost to producing cleaning agents. Equipment, raw materials, and bottles for cleaning agents all cost money.The order just sent by Bei Dao Zhengshen has a total of 10 bottles. The shipping price of Canghua Technology and Trade is 10 yuan per bottle, the cost is almost 5 yuan, and the profit is half.

But if, as Gao Fan just said, the new formula is regarded as an enhanced version and the price is increased by 20%, the 20% is pure profit, because the new formula does not cost more raw materials than the old formula, and the investment in equipment and manpower is the same.

Calculated in this way, 10 bottles can earn an extra 20 yuan. If Yang Kai is given half of it, it will be 10 yuan.

Yang Kai didn't calculate this account at first, but said that half of it was too little out of ridicule. When he realized it, he realized that the so-called half was actually 10 yuan, which made him dare to ask for it.

"Or, just 5%, 20 miles, and I'll give you 1." Gao Fan immediately reduced the share ratio to 1/10.

"This is absolutely not acceptable." Yang Kai said, "I was joking just now, so don't take it seriously."

"But I'm serious, you must not take it as a joke." Gao Fan said.

Yang Kai said seriously: "How can this work? I counted this formula out of interest, and by the way, I can help you optimize the product. This kind of thing is just a matter of little effort, how can I collect money."

"Free things are the most expensive." Gao Fan said, "If you don't mention this, I haven't thought of it yet. Next, I will ask the Department of Chemical Engineering to help us develop new products and new processes, and set the cost standard in advance. necessary.

"You think that we can make a lot of money by putting it in our company. If the mechanism of industry-university-research linkage cannot be clarified, there will definitely be disputes in the future."
