Chapter 281 Manufacturing

At this time, Xia Lin didn't know that someone was staring at him again, but even if he knew, he wouldn't care about these gazes. Now relying on the queen and the industrial park, his power is no longer as weak as before , and has even been able to squeeze into the hunting circle of a group of giant crocodiles in Helgana, competing for a piece of their own territory.

After the notice was issued, relying on the huge population of the new district, Xia Lin gathered the raw materials needed for small-scale production the next day. A simple collection and filtration device was built in the open-air straw shed in the downwind of the industrial park. Wearing a mask, you can still smell the terrible stench leaking from the device. These foul-smelling gases are filtered into the water through purification technology, and then form strong ammonia water, which is sealed in wooden barrels coated with tung oil for storage.

Not far from the hut, the newly built glass factory has been specially divided into an area to build a huge concrete pool.The pool made of masonry concrete is rectangular as a whole, with a size of 4*2*1.2. There is a kang path for heating at the bottom, and a long channel with a purification rune plate is connected to the edge of the upper side.

Xia Lin asked people to paste tiles produced by the porcelain research and development team in this pool, and built a simple starch hydrolysis pool, and then began to prepare another important raw material for the silver mirror reaction.

First, fresh potatoes are crushed into pieces by a human-driven press, and the pieces and juice are manually swept into a stone mill for grinding. The ground off-white milk powder is filtered three times, and finally a starch solution is obtained.

After standing for a while, the off-white starch precipitated in the lower layer can be directly added to the starch hydrolysis tank, and at the same time mixed with hydrochloric acid produced by the caustic soda plant, and then under the heating of the kang road below the hydrolysis tank, the starch undergoes hydrolysis reaction, and the final glucose product is With the help of purification techniques, they gather at one end of the hydrolysis pool, and begin to purify and separate through the long channel.

Through titration with iodine water prepared with kelp ash, after confirming that the solution produced at the end of the long canal does not contain starch, Xia Lin obtained a fairly pure glucose raw material.

The next step is to use these complete raw materials to make glass mirrors. The laboratory operation of this step is quite simple. First add a dilute solution of sodium hydroxide to the silver nitrate solution, and then gradually add concentrated ammonia water. The brown silver oxide in the solution is about to precipitate. When it disappears, add dilute ammonia water until the precipitate is just completely dissolved.

Xia Lin first tried it with the beaker, test tube and other utensils he brought, and successfully obtained the silver ammonia solution, but if he wanted to configure it in large quantities and use it in the production of mirrors, some additional equipment and steps were needed.

After finding suitable equipment, Xia Lin began to explain in detail the process of making mirrors to Gunther Herbert, the person in charge of the mirror production line, and the twelve team members who were assigned to be in charge of silver ammonia solution configuration. A series of steps highlights:

"Here is the most critical point. When configuring the solution required for the mirror reaction, you can use concentrated ammonia water for configuration at the beginning, but after the precipitation in the reaction tank is almost gone, you must manually add dilute ammonia water slowly, and at the same time keep stirring until precipitation Just disappear completely, too much or too little will affect the effect of the solution.

At the same time, this solution is very unstable. If the raw materials allocated by the glass factory are not enough and production needs to be stopped, the silver ammonia solution prepared here must be disposed of on the same day, and the liquid marked with dilute sulfuric acid is added to it.

Wait until the color of the test paper is red, then add the sodium sulfide powder, this powder is dangerous, so remember to wear gloves when taking it from the warehouse, and remember to collect the precipitate after the precipitation is complete. it is good.

Do you understand?I still have a lot of time, you don’t have to pretend to understand, as for this kind of thing, every link must be kept in mind to produce qualified products. "

Xia Lin looked at the team members around him who seemed to be in a daze, and asked with a frown.

"Boss Xia Lin, in fact, from the beginning of that precipitation, I don't quite understand it..."

Seeing that Xia Lin seemed to attach great importance to this project called the glass mirror, Gunther scratched his head and said with some embarrassment that he was the youngest part of the group of people who decided to follow Xia Lin in the Tongshou District. Later, because his brain was still easy to use, he was transferred to a soda ash factory as a workshop manager, and he had some knowledge of chemical engineering, but that knowledge was not enough to help him understand these chemical terms like a bible.

Seeing that the leaders of their project teams looked like this, the others also said things they didn't understand.

Xia Lin collected what they mainly explained that they didn't understand, and found that they were basically some basic chemical problems. After thinking about it, he said:

"Ask questions when you don't understand. It is a good virtue in chemical production. If you do it blindly, this project will have big problems sooner or later. Gunther, you have done a good job in this area. I hope that you can maintain this kind of virtue when you encounter any problems in the future." Attitude, if you have any unanswerable questions, you can report them to my office.

I just listened to everyone’s reactions, and most of them are relatively basic questions, but now there is no room for you to learn these knowledge, so let’s just leave it like this, I asked Xinglan Elementary School to give you some nature textbooks for self-study, as for production I will write all the things for you step by step, and you can just follow the steps. "

As Xia Lin said, he demonstrated according to his own foolish production steps:
"For example, the first step in preparing silver ammonia solution is to add the water marked with silver nitrate to the reaction tank, add five clay pots at a time, and then add one pot of water marked with sodium hydroxide, and wait until this brown thing After it appears, use a spoon to add the stinky water from the grass shed. When the brown thing is about to disappear, replace it with another stinky water that we added ourselves...

In this case, can you understand? "

Xia Lin completely decomposed the production steps into small links, explained the main points of each link in a way that this group of employees could accept, and finally asked.

"All in all, it is to add other strange waters to these strange waters, right? Boss, I probably understand! But the names of these waters are too strange, such as silver or oxygen, I think it is better to use them directly It is convenient to mark it with numbers.”

After getting rid of those weird chemical terms, Gunther suddenly realized, and then complained a little.

"Is it marked with numbers? This seems to be okay, since this is the case, let's use numbers to refer to these solutions in the future!"

Xia Lin thought for a while and felt that for a group of chemical illiterates who don't even know what hydrogen and oxygen are, it is really useless to label those complicated solution terms, so she readily accepted Gunther's good idea, which can also play a role in the process. Some role of secrecy.

Although Xia Linsheng's translation of chemical terms is complicated, you can still see what the roots represent, but if you use numbers instead, there is basically no risk of leaking.
