Abu then chatted with Liu Yuanlu about how women remove stains when they wash clothes.

Liu Yuanlu thought for a while and said that most of the clothes are washed with plant ash, but its decontamination effect is not very good.

The bath beans used in bathing are mainly made by using pig pancreas, but because the current scale of pig breeding is not very large, the output is relatively small.

Abu replied that in fact, the scale of cattle and sheep breeding is not small, but the cattle and sheep pancreas have their own smell, and if they are used to make bath beans, they will be covered with an unpleasant smell and are mostly abandoned by everyone.

But if they can be deodorized during the manufacturing process and used to make soap, soap or something, it will be more slippery and suitable than pig pancreas.

"The third brother also knows about this? Let's hear it. Liu Yuanlu became interested, he poured a glass of wine for Abu and himself respectively, and intentionally or unintentionally, kept shaking the wine glass and swaying in front of Abu's nose.

It took Abu a long time before he realized: Oh, it turns out that the container for wine is made of glass, a veritable glass cup, which is silently showing his superiority.

Blaming yourself is too commonplace in the later life, and the expression on your face at this time should be full of surprise, or even a cry of surprise, okay?

Then Abu, who suddenly came to his senses, exclaimed: Wow! It turns out that the second brother has already used such a high-end glass?! Where did you get it? Did you do it yourself? ……

Liu Yuanluyun waved his hand lightly, this is nothing! However, his slightly narrowed eyes and the long lock of hair that was slightly upturned completely betrayed his inflated vanity and full of pride.

After the drama of flattery and modesty, the two talked more happily!

Abu told Liu Yuanlu the general process, and the specific details still need to be grasped by Liu Yuanlu himself, after all, he has not practiced it himself.

The first step can be called hydration oil refining, first the fat of cattle and sheep is heated to a certain temperature, and then steam is introduced, and the diluted salt and soda ash solution are added at the same time.

Stir evenly to mix and fully emulsify the water and oil. After standing, the hydrate of the lower layer is separated and removed, and the oil containing little phospholipid and protein can be obtained.

When grease is heated, it produces low molecular weight aldehydes and ketones, which are the main source of odors.

The main purpose of the water vapor is to remove odors and at the same time to emulsify the heated oil.

Liu Yuanlu listened with relish, and what he liked most was to hear these strange terms in Abu's mouth.

Although he didn't quite understand what these things were, it didn't prevent him from using these terms and pretending to show off his intelligence in front of others.

The second step is saponification, and the oil separated from the first step is sent into the soap pot, and at the same time, steam is pressed in, and calcium hydroxide solution is sprayed.

Liu Yuanlu was a little dazed, and subconsciously asked Abu.

What did you say? You don't know what calcium hydroxide is?

Haha, add the quicklime we produce to water, clarify and cool, and the upper layer is calcium hydroxide solution.

Oh, let's move on, and then add the soda ash solution until all the saponification is complete. Then saturated brine is added, and the soap is precipitated through salting out, and the soap should be kept to boil evenly throughout the whole process.

After this step is completed, let it stand for three hours to obtain soap grains after saponification and salting.

The third step is washing, putting the soap particles obtained in the second step into clean water, boiling, and dividing the granules into a uniform shape. Then saturated brine is added again, salting out, and after standing for a long time, what you get is soap.

The quality of the top layer is the best; There are more impurities in the lower layer, which can be recovered and the above steps can be carried out again.

That's all, it's easy!

Liu Yuanlu touched his beard and was silent, it was indeed very simple. Abu also explained it simply and clearly, and the purpose and operation steps of each step were clearly explained.

But when it comes to implementation, there is nothing, you have to design drawings from scratch, manufacture boilers from scratch, grope for dosage from scratch, and conduct tests.

Liu Yuanlu felt that it would definitely be difficult for him to do it from scratch.

This is not like the last alkali production, which was carried by Abu, and he was allowed to do whatever he wanted, and he basically didn't need to use his brain.

Abu didn't want to be lazy, but this time the working environment was basically about 100 degrees of boiling water, and the difficulty coefficient was not very large.

You should boldly let go of your hands and exercise the independence of others. If you have to do everything yourself, then you have to die of exhaustion.

Seeing that Liu Yuanlu was afraid of difficulties, Abu followed the temptation. He took pen and ink and a piece of paper from the side, and said, "In fact, in this refining process, an extremely complex chemical reaction has occurred, and I will explain it to you below."

The grease is put into water, and after heating, the grease reacts with calcium hydroxide to form calcium soap, and then the sodium carbonate is used for replacement reaction to produce sodium soap, which is the soap we want.

Finally, using saturated brine can separate glycerin from soap particles, you see, that's their chemical reaction formula. ”

Brushing brush, Abu After a while, the formula was written on the paper, and Liu Yuanlu stared at it with wide eyes and looked carefully.

Abu handed the written formula to Liu Yuanlu and watched quietly beside him, he knew that Liu Yuanlu had a hobby of collecting various chemical formulas.

Liu Yuanlu stared at the dense paper, his eyes glowed, and he looked at it repeatedly, his face showing a fascinated and complicated color.

In the past, when he and his father were operating the way of alchemy, the acquisition of each Dan recipe was all arduous and costly. Even have to pay a huge amount of money to exchange it with others.

Every alchemist regards the Dan Fang as more important than his life, and every time he gets a new one, he carefully collects it and never shows it easily.

Where is like Abu, write it out casually and give it away, and it is accompanied by instructions and detailed explanations of specific links.

Abu continued: "Actually, this is just a preliminary plan, if we have spices or essences in the future, we can make more high-end soaps."

At that time, these soaps and soaps can be used for bathing and washing the face, and it is simply easy to make money every day.

You can also try adding some cane sugar, and you'll find that the soap will become transparent.

You see, what a wonderful chemistry it will be, what a great miracle it will be, what an intoxicating experience it will be to explore the mysteries of the chemical world and open the door to the unknown......"

Liu Yuanlu's blood suddenly gushed upward, his eyes were round, he gasped heavily, and said to Abu: "Third brother, don't say it, I'll do it!" I'll start with drawings tonight, design, and if I really can't get over the hurdle, you can help me check it. ”

"Something else, second brother, I haven't finished talking yet. In the end, the glycerin that is separated, don't throw it away, it's a good thing, remember the nitrocellulose we made before? ”

"Of course I remember, then how can I forget, in the last experiment, I almost lost my leg." Liu Yuanlu palpitated, and a trace of fear flashed on his face.

"This glycerin, in fact, is the same as nitrocellulose, which can make a more powerful and stronger zha yao."

Liu Yuanlu was so frightened that he almost jumped up from his chair: "Such a dangerous thing, then why do we keep it?" ”

"Haha, second brother, please rest assured, under normal circumstances, glycerin is very safe. But what you need to be careful about is that you must store them separately, and never let them touch nitric acid and sulfuric acid. ”

"It's so dangerous, why don't you just throw it away." Liu Yuanlu felt a little chill in his spine, and it seemed that the explosion last time had left a great psychological shadow on him.

"Don't, it's very useful, if you don't do zha yao, we can make a lot of other products."

The second brother should know that the scientific and reasonable industrial system is recycling, and the waste in industrial production is likely to be the necessary raw material for the next process. ”

Liu Yuanlu thought for a moment and replied to Abu: "Hmm! What the third brother said was very reasonable, and the second brother was taught. ”

The two chatted for a while, and then Abu got up to say goodbye, feeling a sense of accomplishment in his heart. Being able to cheer up others and improve work enthusiasm and enterprising spirit is the job you should do.

As soon as I went out and turned a corner, I saw several people walking towards me. When I got closer, I found that it was several young women who had just finished class, all wearing thick cotton skirts, well-cut clothes, and full of youthful charm. One of them is the Zhang Caier who hanged herself a few days ago.

When they saw Abu, they all saluted and greeted Abu.

After Abu returned the salute, he turned to Zhang Cai'er and asked, "How do you feel now?" ”

Zhang Cai'er's face was calm and a little shy, and she replied to Ab Shili: "Thank you sir for your concern, my body is fine." ”

"Well, remember to apply the ointment I gave you last time once or twice again, it should be fine. Rest assured, there will be no scarring. It's always a good thing to be young and energetic. ”

When they said goodbye to each other, returned home, and were alone, Zhang Caier leaned softly against the wall, and her face showed a drunken redness.

The calm and calm in front of Abu just now seemed to drain all her strength.

Mr! How nice it would be if you always cared about me like that!

Since that incident, she has buried her heart like a seed. As a result, obsession is also like a seed, germinating, pumping, thriving, and holding the body and mind.

When she knew about the rescue process of her husband, she was cruel to herself, why didn't she wake up at that time; Otherwise, you will know what it feels like when your husband kisses you......

She touched her lips, like a lazy cat, leaning there and muttering to herself.

Mr! Do you know how much I like you, you can dislike me, but you can't...... Stop me from liking you!

Mr! I can do anything for you, even ...... It's death! Mr. Woman...... Can you?
