Li An ’s new coating for Research & Development is stronger and more durable than the existing materials, and has a certain degree of water resistance. When you gently swipe with your fingers, there will be no white powder on your fingers. It is a really good material, which will greatly improve the effect of architectural decoration.

What Li An expects most is imitation porcelain coating, which is also the direction of Li An development. However, because the ingredients required for imitation porcelain coating are too much, and the cost of many materials is relatively high, even not yet studied Yes, so Li An wants to study the same porcelain-like coatings as in later generations. I am afraid it will not be easy. However, the pressure of studying a simple version of porcelain-like coatings is not great. Li An is very confident about this.

Gently grabbed a handful of lime powder, Li An rubbed it gently with his fingers, feeling the burning sensation of the palm of the lime powder, and then gently sprinkled the lime powder, allowing the lime powder to float with the wind.

In the process of mining limestone, it is inevitable that lime powder will be scattered, forming a white soot. This soot is very harmful to the human body and will burn the skin. If it enters the eyes and respiratory tract, it will The damage is even greater.

But this soot is inevitable, and no matter how gentle the mining method is, the lime powder will not be fluttered with the wind. Naturally, it is difficult to avoid the rising white soot causing harm to the craftsman’s body.

The defensive power of the skin is still relatively strong. The short-term lime powder attachment will not cause too much damage to the skin, but the resistance of the mouth, nose and respiratory tract to the lime powder is weaker, and when the person is working In particular, when doing heavy physical work, breathing is more intense. If there is no protective means, the working craftsman will inevitably inhale a large amount of lime powder in the process of mining the lime mine, thus causing great damage to the body , Maybe you’ll breathe one’s last in a few years.

In order to avoid too much damage to the craftsmen, Li An prepared a thick mask for them. With the protection of the mask, they can greatly reduce the damage caused by the lime powder to their respiratory tract and protect their life and health.

In addition, even if the weather is hot, they must wear neatly when they are working, and cover their bodies as tightly as possible. Both gloves and hats must be worn, and the hat must have a brim to protect the neck, so protective If a craftsman can be exposed, only eyes will be left.

The time of one work can not be too long. If you work too long, a lot of lime powder will accumulate on the clothes. The mask will also be blocked by the lime powder. It needs to be cleaned well before it can be used again.

According to the requirements of Li An, the staff of the lime mine, as long as they are exposed to lime, can only work for 4 hours a day. The rest of the time should be well rested, and all the clothes and masks should be cleaned to facilitate the second Continue to work.

Not far from the lime mine is the cement workshop under construction. This cement workshop has a large construction scale and a lot of storage warehouses. As long as it is put into production, it will inevitably be able to produce a large amount of cement products to support the safety Construction of Zhugang.

“Minister Li, the cement workshop is under construction. After the construction of the cement road is completed, the cement workshop can be completed and put into production.”

The subordinates responsible for supervising the construction stepped over to Li An saluted.

“Oh, that’s really great. Remember, not only the speed, but also the quality. It’s a daunting task to ensure quality and quantity.”

Li An said.

“Yes, Minister Li, my subordinates understand.”

The subordinates were busy.

“Huh, why don’t you go to dinner.”

Li An asked when he saw the artisans standing and squatting all around.

The subordinate just secretly ate lunch, and naturally he would not eat second time anymore, busy saying he had eaten it.

Li An will naturally not pursue this subordinate for the crime of stealing food. As a leader, there is nothing wrong with eating ahead of time. He has also secretly eaten just now, and he has also brought many people to eat with him.

Seeing the methodical construction of the cement workshop with his own eyes, Li An felt more at ease. The guidance was already understood, and all the inspections had been inspected. Li An returned to Harbor in the afternoon with lime.

“Minister Li, what are you painting, it looks so strange.”

Bai Hu stood next to Li An and saw the picture drawn by Li An and asked blankly.

“Why.” Li An looked back towards Bai Hu and smiled slightly at the corner of his mouth: “Is this official painting bad?”

“This is also good.” Bai Hu curl one’s lip, with an incredible expression on his face, spit out: “This is just a circle, just a few vertical lines drawn outside.”

“This is the Colosseum.” Li An smiled and continued to draw, and said: “In a few days, This Official will take you to see what a wrestle is.”

“Fighting.” After a short pause, Bai Hu’s forehead pimples were still unrelieved. He wondered: “What do you mean by fighting, do you fight?”

“Yes.” Li An paused, said with a smile: “Neither.”

“Yes, it’s not.” Bai Hu was even more puzzled and asked coquettishly: “Isn’t that right? Tell others soon!”

“Okay.” Li An made a grimace, said solemnly: “Fighting is more brutal than fighting, the losing side is going to be killed, understand.”

Bai Hu was startled and whispered: “This is too cruel, why should it be so cruel?”

Li An knew that Bai Hu was kind, but if only who would say who would participate in the fight, it is estimated that she would not have this sympathy.

“Do you hate pirates?” Li An looked towards Bai Hu lightly, carefully observing Bai Hu’s expression changes.

“Of course I hate it.” Bai Hu’s expression looked very excited, and said angrily: “If the pirate robbed the father’s merchant ship, I would not destroy my family, so I would like to spit the pirate’s meat to relieve the hatred . “

Looking at Bai Hu, whose face muscles are shaking, Li An indifferently said: “Gladiators are these pirates. This Official let them kill each other, do you find it very interesting, do you still feel cruel?”

Bai Hu’s expression stopped for a moment, and he quickly resented the expression of approval.

“It was still a charming expression just now. When I heard that pirates were killing each other, they immediately became terrifying.”

Li An said with a smile.

“Minister Li, This Slave of Yours lost self-control.”

Bai Hu realized that he was too excited just now and opened the mouth and said apologize.

Li An naturally does not care, gently embrace Bai Hu in his arms, kiss Bai Hu’s ear and cheek, indifferently said: “Bai Hu girl, do you know where you are most fascinated by this official?”

“This …” Bai Hu looked a little shy, thought about it, and took the head: “This Slave of Yours is unknown.”

“Here.” Li An gently stroked Bai Hu’s lower back, indifferently said: “Bai Hu girl’s back waist has 2 large waist pockets, very charming, the average girl does not have it? Very rarely seen. “

After a few strokes, I stroked a few times and told Bai Hu with my fingers, where are the two waists.

“Waist?” Bai Hu frowned, she didn’t know that she had a waist, paused, said with a smile: “No wonder Minister Li always likes to kiss the back of this Slave of Yours. Was there a waist socket, did Xiqi elder sister have it? I’ve seen it, it doesn’t seem to be, let me touch it myself. “

Gently stroking his lower back, Bai Hu smiled at the corner of his mouth, squinting looked towards Li An, and abused: “Really, there are really 2 recessed places in the lower back, so strange! I have seen it There are no people, no mother, no little fox, no nanny … “

Talking and talking, Bai Hu himself felt that he was a very interesting top grade woman who actually had a waist pocket that no one else had.

It is said that among all women, the proportion of the body with a waist socket is only 3%, which can be said to be a very low ratio. It is definitely called top grade, which is actually the proportion that can experience the tide. The same, they are all top grade.

Li An laughed, I thought to myself, you, a Little Lass, have only seen a few women, I have seen so many women, there are only a few waist dimples, and every woman with a dimple in the back, all It’s a top grade beauty.

“This Official has not seen a few, and Bai Hu’s waist is one of the most beautiful. It makes people put it down. Unable to bear should kiss a few more times.”

Li An grinned badly.

Bai Hu already not in shy, snuggled gently in Li An’s arms, very endearing little bird, with an intoxicated expression.

Bai Hu, who is holding an endearing little bird in his arms, Li An is reluctant to throw it away. However, if she sees all the young and beautiful girls take away, Li An will take a few hundred people along the way and sit The boat can’t stand it anymore.

In the early morning of the second day, Li An did not go to the north to inspect. Instead, he studied imitation porcelain paint in Harbor. According to his own memory, the composition of imitation porcelain paint is more complicated, including calcite powder, zinc white powder, light calcium carbonate, and double flying powder. Gray calcium powder, distilled water, ethyl cellulose and other materials.

Some of these materials can be researched, and some are difficult to research. However, as long as there are only a few of them, mixing them together will definitely be effective.

Among them, calcium carbonate is the easiest to manufacture. Calcium carbonate can be produced by adding quick lime to water, and gray calcium powder is produced by calcination of calcium carbonate at high temperature to Calcium Oxide and then through selection and other methods. The main ingredients are Hydrogen Calcium Oxide, Calcium Oxide and calcium carbonate are the refined products of lime.

Most of the remaining raw materials are also manufactured through lime processing. As long as there is lime, these materials can be manufactured, and then, together, they can produce imitation porcelain paint.

Imitation porcelain coatings can be divided into 2 categories according to their characteristics. The first category is solvent-based resins, whose paint film is bright, hard and full, resembling enamel, and has excellent water resistance, alkali resistance, wear resistance and aging resistance And strong adhesion.

The second is the construction method of water-soluble resins by batch scraping and sanding. The appearance of the finish is similar to enamel. It has a smooth feel when touched by hand. Most of them are mainly white paint.

Due to the application of scrape coating, the coating film is hard and dense, and has a certain adhesion to the base layer. Under normal circumstances, it will not bulge or blister. If it is coated with an appropriate glazing agent on it, the resistance to pollution and other properties are all It has been improved. The coating film of this kind of coating is thicker, not water resistant, has poor performance, more troublesome construction, single color, and general decoration.

In addition, the imitation porcelain paint can also be added with various fuels, so that the painted wall shows a variety of colors, but in general, it is still the best white, one does not need to add any pigment, the lowest cost, 2 is The white walls are the brightest. People living in Lima Club are very comfortable. Another point is that the walls of pale blue, pink, and yellow will look pretty at the beginning, but for a long time. , The walls will look very worn, and the white walls will never be outdated.

Because I have the knowledge of making imitation porcelain paint in my heart, Li An knows what to do with a little bit of thinking. On the boat, there is a special laboratory with Li An bringing various experimental materials from Chang’an City. For example, beakers, measuring cups, and alcohol lamps are all available.

Li An conducted experiments according to his own memory and little by little’s patience, and soon achieved a huge breakthrough. The raw materials needed for various imitation porcelain coatings such as gray calcium powder and light calcium carbonate, all were studied after one after another. come out.

In the end, Li An mixed all these materials together in the required ratio and fully stirred them to produce the first Great Tang version of the porcelain-like coating.

This imitation porcelain paint has only one bucket, at most it can only paint one wall, and Li An does n’t want to paint the wall yet. After all, there is no comparable reference. In the case of decoration, how did these merchants deal with the interior walls of the house without lime material?

Li An took a small number of subordinates, went to the first street, and walked into a building in person, which was busy renovating.

It was a fat businessman who rented this floor. When Li An came in, he stooped forward and said hello.

“Minister Li.” The fat businessman couldn’t help smiling.

Li An did not respond, just slightly nodded, and then began to seriously appreciate the decoration in the room.

The rough wall of the room is the side of the brick and the cement gap, which is very rough and very dark. If it is not decorated, it is too ugly, and the decoration strategy adopted by this businessman is wood decoration, that is, on the surface of the wall Lay a layer of wood, and one-sided polished wood, after the laying is completed, then paint on the wood, so that the whole room looks more luxurious.

Because this is a restaurant, the soup is usually easy to spill on the ground, so the ground can not use wood, but choose to lay a cement floor, which is the most durable.

Of course, it is better to lay ceramic tiles, but the cost of ceramic tiles is too high. In the era of Great Tang, ceramic tiles were just researched that’s all, only available in Great Tang. There are no workshops for producing ceramic tiles overseas. From Great Tang purchase, the light transportation fee can scare people, and I am afraid that this boss has never heard of this thing.
