Soap factory.

After leaving the spinning factory, Lin Mu and Duanwang and his entourage arrived here, since Lin Qing and Lin Yang came back, the two of them recruited some of the shopkeepers who had to be used by the Lin family before, and the number of available talents in the firm expanded, and the efficiency of work was naturally improved.

Almost at the same time, the spinning mill, the caustic soda factory, the soap factory, and the expanded weaving mill were all put into production, and the Lin firm was no longer an empty shelf, but truly became a large commercial house with many factories under its jurisdiction.

At the same time, Lin's firm is also forming a regular civil construction team, which is what he requested.

The reason for the construction team is simple: the architecture of the Hua Dynasty is magnificent and exquisite, but it is not suitable for use as a modern factory building, after all, the probability of a wooden mechanism catching fire is too great.

If there is a professional civil construction team, his professional workshop will not be worried in the future.

At the same time, this professional construction team can also contract various civil works of the Hua Dynasty, in his opinion, whether the Hua Dynasty wants to change or not, the Western robbers in the nineteenth century will force the Hua Dynasty to modernize, when all kinds of factories, infrastructure rise, his construction team will be useful.

"I didn't expect the soap to be made from meat oil and vegetable oil."

Standing in front of a rectangular pool of soap liquid, Duan Wang couldn't help but cover his nose, as a prince, he has been clothed and fed since he was a child, and he has never seen a picture of barrels of greasy meat oil boiling.

"Your Highness, this is the magic of chemical reactions, what looks disgusting to ordinary people can be turned into gorgeous things after reaction." When Lin Mu accompanied Duanwang on the inspection, he was also inspecting his factory.

Because of the popularity of soap, Lin Mu built a soap factory covering an area of 40,000 square meters, and 50 pools were built just for boiling soap liquid, and the amount of soap produced from here every day was very considerable, and it would not be long before the soap factory would complete all the orders and sell the soap to other places outside the Hua Dynasty.

In the nineteenth century, which was a century when international trade was beginning to take shape, the market of the Hua Dynasty was only a small part of the world market, and more markets were waiting for the Lin firm to open up.

"Chemistry?" King Duan heard it in a fog, and he said: "If you are free, you should come to the palace to tell the king, the more you come into contact with the forest attendant, the more the king feels that the world is big, and there are no surprises." ”

"Yes, Your Highness." Lin Mu thought that he should brainwash Duan Wang when he had time, so he didn't believe that he couldn't fool him with his words in the shopping mall.

After observing the whole process of making soap, Duanwang became interested in the crucial caustic soda, and he said: "Lin Shi said, what is this caustic soda?" ”

"Your Highness, please come with your subordinates." Lin Mu pointed to a door in the middle of the wall of the soap factory, opposite the caustic soda factory, and in order to facilitate the provision of caustic soda, he deliberately put the two factories together.

When Lin Mu arrived next door, Duanwang saw that there were twenty pools on the ground, which were full of white mud at this time, and on top of the white mud was a layer of clear water, and a layer of white film was floating on the top of the clear water, as if the water was frozen.

Lin Mu picked up the wooden stick and picked up some frost-like things and said: "Your Highness, this is caustic soda, if you take out the water and boil it, you will get more caustic soda, these are just naturally dried." ”

Duan Wang became more and more surprised, he pointed to the white mud and said, "Is this white mud all this?"

"No, it's hydrated lime that settles down there." Lin Mu brought out all kinds of professional words, he was not pretending to be forced, but because no matter who he was, he would trust people with professional words more, and at the same time, it also made him look professional.

"Hydrated lime? Is it also used to make soap?"

"No, but hydrated lime has a big effect." Lin Mu said that many people pay special attention to caustic soda because of soap factories, but ignore the role of hydrated lime.

In modern times, hydrated lime is often used to sterilize and disinfect chicken and pig houses, mix sand as a binder when building walls, keep eggs fresh, make preserved eggs, and even improve acidic soils, treat sewage, build roadbeds, and configure pesticides.

These effects make hydrated lime also have commodity value, so his caustic soda plant produces caustic soda and sells hydrated lime at the same time.

Explaining the role of hydrated lime, Duan Wang was amazed, and after this circle, he found that Lin Mu's factory was full of treasures.

"Tut-tut......" made a burst of exclamations, Duanwang came to the limestone stacked in the factory, and Duanwang had never seen this thing.

But he didn't ask about the limestone, but looked directly at the two large chimney buildings that had been erected.

"There was water in the pool just now, and this thing seems to be used for fire." Duan Wang asked.

"It's used to calcine limestone." Lin Mu is very satisfied with these two buildings, and the production of industrial materials is sometimes one after another, such as his caustic soda factory.

Calcined limestone can obtain quicklime, quicklime and soda ash are mixed to obtain caustic soda, limestone is used as a flux for ironmaking, gangue is removed, quicklime is used as slag material for steelmaking, and harmful impurities such as sulfur and phosphorus are removed for steelmaking.

In other words, the caustic soda plant's products are multi-purpose, which is why he reserved space for the cement plant and the glass factory when he planned it.

Another explanation, Duanwang was basically a little dizzy by the complex knowledge that Lin Mu said, and he originally wanted to pretend to guide him, but he found that he didn't understand anything, and finally didn't say anything at all, so as not to be laughed at by Lin Mu when the funnel was full of funnels.

Out of the caustic soda factory, Duanwang didn't want to look any further, he understood one thing, that is, it was impossible for him to learn so much knowledge in a limited time.

Such a professional and specific thing can only be done by people like Lin Mu, what he needs is a simple understanding and supervision, after all, as a prince, he needs to focus more on dealing with government affairs, and what he wants to learn from Lin Mu is not anything like chemistry and physics, but the part of Western law about government affairs.

"Lin Shi said, when I saw it today, this king felt that he was just a frog at the bottom of the well, and I hope that Lin Shi will be able to teach him in the future." King Duan put away the arrogance of the superior, and said with the appearance of a humble student.

Lin Mugong said: "Your Highness can be eclectic, and it is the luck of the lower officials not to regard what you see today as a sideline, as for the teaching, the lower officials naturally dare not hide it." ”

King Duan nodded and smiled, "Because of the status of the prince, this king can't choose his own teacher, but in the future, this king will wait for Lin Shi to teach a teacher's courtesy, you and I are also teachers and friends, and I also hope that Lin Shi will not be estranged because of the identity of this king." ”

"Xiaguan understands."

Lin Mu relaxed physically and mentally, the relationship between him and Duanwang during this time was indeed a little too rigid, after all, the relationship between superiors and subordinates was there, but he didn't expect Duanwang to take the initiative to resolve this embarrassment.
