The new coating to be developed by Ang Lee is more durable and durable than the existing materials, and has a certain degree of waterproofness, and when you gently swipe your fingers, there will be no white powder on your fingers, which is a really good material and will greatly improve the effect of architectural decoration.

What Ang Lee is looking forward to the most is melamine coating, which is also the direction of Ang Lee's development, however, because there are too many ingredients needed for melamine coatings, and there are many materials with relatively high costs, and even, they have not been researched, so Ang Lee wants to study the same melamine paint as later generations, I am afraid it is not easy, however, the pressure is not too great to study a simple version of melamine coating, and Ang Lee is very confident in this.

Gently grabbing a handful of lime powder, Li An gently rubbed it with his fingers, feeling the burning sensation of lime powder on his palm, and then gently sprinkled the lime powder, letting the lime powder drift away with the wind.

In the process of mining lime ore, it will inevitably cause the lime powder to drift away, forming a white smoke, which is very harmful to the human body, will burn the skin, if it enters the eyes and respiratory tract, it will be more harmful to people.

But this smoke and dust is unavoidable, and no matter how gentle the mining method is, the lime powder cannot avoid the wind from blowing, and it is naturally difficult to avoid the white smoke that rises and causes damage to the body of the craftsman.

The defense of the skin is still relatively strong, the short-term lime powder attachment will not cause much damage to the skin, but the resistance of people's mouth, nose and respiratory tract to lime powder is relatively weak, and when people are working, especially when doing heavy physical work, the breathing is more intense, if there is no means of protection, the craftsman who works will inevitably inhale a large amount of lime powder in the process of mining lime mines, thus causing great damage to the body, maybe he will die after a few years.

In order to prevent the craftsmen from suffering too much damage, Ang Lee prepared thick masks for them, with the protection of masks, they can greatly reduce the damage caused by lime powder to their respiratory tract and protect their lives and health.

In addition, even if the weather is hot, when they work, they must be dressed neatly, cover their bodies as tightly as possible, gloves and hats must be worn, and hats must have a brim that can protect their necks, so that only the eyes of a craftsman can be exposed.

If you work for too long, a lot of lime powder will accumulate on your clothes, and your mask will be blocked by lime powder, which needs to be cleaned well before you can reuse.

According to Ang Lee's request, the staff of the lime mine, as long as they are in contact with lime, can only work for four hours a day, and the rest of the time should have a good rest, and clean all the clothes, masks and other materials so that they can continue to work the next day.

Not far from the lime mine is the cement workshop under construction, which is built on a large scale and has a lot of storage warehouses, which will be able to produce a large number of cement products to support the construction of Anzhu Port as long as it is put into production.

"Li Shilang, the cement workshop is under full construction, and after the cement road is completed, the cement workshop can be completed and put into production."

The subordinates who were in charge of supervising the construction walked over and saluted Li An.

"Oh, that's great, remember, not only speed, but also quality, the complete task of quality and quantity."

Li An said.

"Yes, Li Shilang, my subordinates understand."

The subordinates were busy.

"Hey, why don't you go to dinner?"

Li An saw that there were all craftsmen standing and squatting eating around him, and asked.

This subordinate secretly ate lunch just now, so naturally he wouldn't eat it a second time, and he was busy saying that he had eaten it.

Li An naturally will not pursue the crime of stealing food from this subordinate, as a leader, there is nothing wrong with eating in advance, he himself also secretly ate just now, and he also brought many people to steal food together.

Seeing the cement workshop being built in an orderly manner, Li An was immediately much more relieved, the guidance was already known, and all the things that should be inspected were inspected, and Li An returned to the port in the afternoon lime.

"Li Shilang, what are you drawing, it looks so strange."

The white fox stood next to Ang Lee, saw the picture drawn by Ang Lee, and asked with a blank face.

"How." Li An looked back at the white fox, and smiled slightly at the corner of his mouth: "Isn't this official's painting good?" ”

"That's good, too." The white fox pursed his lips, with an expression of disbelief, and complained: "This is a circle, and a few vertical lines are drawn on the 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 gladiatorial combat is." ”

"Gladiatorial fighting." After a pause, the pimple on the white fox's forehead still hadn't calmed down, and he asked suspiciously: "What does gladiatorial fighting mean, is it a fight?" ”

"Yes." Li An paused for a moment and smiled: "Not either." ”

"Yes and no." The white fox was even more puzzled, and asked coquettishly, "Is that really it?" Tell someone! ”

"Okay." Li An made a grimace and said in a deep voice: "Gladiatorial fights are more ferocious than fights, and the losing side will be killed, understand." ”

The white fox was startled and said softly: "This is too cruel, why is it so cruel? ”

Ang Lee knew that the white fox was kind, but if she said who would participate in the gladiatorial fight, it was estimated that she would not have this sympathy.

"Do you hate pirates?" Li An looked at the white fox lightly, carefully observing the changes in the white fox's expression.

"Of course I hated it." The white fox's expression was quite excited, and he said angrily: "If it weren't for the pirates who robbed my father's merchant ship, I wouldn't have been ruined and reduced to this. ”

Looking at the white fox whose facial muscles kept shaking, Li An said lightly: "The gladiators are these pirates, don't you think it's funny for the official to let them kill each other, do you still think it's cruel?" ”

The white fox's expression stopped for a moment, and soon with an expression of approval, he relieved his hatred: "Let these hateful guys fight each other and let them all die." ”

"I still had a delicate expression just now, and as soon as I heard that the pirates were going to kill each other, it immediately became so terrifying."

Ang Lee said with a smile.

"Li Shilang, the slave family has lost its temper."

The white fox realized that he was too excited just now, and hurriedly apologized.

Li An naturally didn't care, gently took the white fox into his arms, kissed the white fox's ear and cheek, and said lightly: "White fox girl, do you know where you are most fascinated by this official?" ”

"This ......" The white fox looked a little shy, thought for a while, and shook his head: "The slave family doesn't know." ”

"Here." Li An gently stroked the back of the white fox and said lightly: "The back of the white fox girl has two large waist sockets, which are very charming, and ordinary girls don't have them?" It's a rare sight. ”

After speaking, he stroked it a few more times, and told the white fox with his fingers where the two waist sockets were.

"Lumbar socket?" The white fox frowned, she didn't know that she had a waist socket, she paused, and teased: "No wonder Li Shilang always likes to kiss the back of the slave family, it turns out that people still have waist sockets here, so does Sister Magpie have it?" I've seen it, it doesn't seem to be yes, let me touch it myself. ”

Gently stroking his lower back, the corner of the white fox's mouth showed a smile, squinted at Li An, and said playfully: "Really, there are really two concave places in the back waist, it's so strange!" I haven't seen anyone, my mother, my little fox, and my nurse ......."

As she spoke, the white fox herself felt that she was a very interesting and superb woman, and she actually had a waist socket that no one else had.

It is said that among all women, only 3% of them have a waist socket on their bodies, which can be said to be a very low proportion, and it can definitely be called the best, which is the same as the proportion that can experience the sense of tide, which is the best.

Li An smiled, thinking in his heart, you have only seen a few women in a little girl, Lao Tzu has seen so many women, and there are only a few women with waist sockets in the back, and every woman with dimples in the back waist is the best beauty.

"There are not many people I have seen before, and the waist socket of the white fox girl is the most beautiful one, which makes people love it, and I can't help but kiss it a few more times."

Ang Lee laughed wickedly.

The white fox is no longer shy, and gently snuggles in Ang Lee's arms, very bird-like, with an intoxicated expression.

Holding the little bird in his arms and the white fox in his arms, Li An was a little reluctant to throw it down, but if he saw the young and beautiful girls and took them away, Li An would have to take hundreds of people along the way, and he couldn't accommodate it on the boat.

Early in the morning of the second day, Li An did not go to the north to inspect again, but studied melamine paint in the port, according to his memory, the composition of melamine paint is more complex, there are calcite powder, zinc white powder, light calcium carbonate, double fly powder, gray calcium powder, distilled water, ethyl cellulose and other materials.

Some of these materials can be studied, and some are difficult to studied, but as long as there are a few of them, they will definitely have an effect when mixed together.

Among them, calcium carbonate is the easiest to manufacture, quicklime is added to water, calcium carbonate can be made, gray calcium powder is calcium carbonate calcined into calcium oxide at high temperature, and then selected and other means, manufactured, the main components are calcium hydroxide, calcium oxide and calcium carbonate, which belongs to the refined products of lime.

Most of the remaining raw materials are manufactured by lime processing, and as long as there is lime, these materials can be manufactured, and then combined together to make melamine coatings.

Melamine coatings, according to the characteristics can be divided into two categories, the first type is solvent-based resins whose paint film is bright, hard and plump, similar to porcelain enamel, with excellent water resistance, alkali resistance, wear resistance, aging resistance, and strong adhesion.

The second is the construction method of water-soluble resin through batch scraping and grinding, and its finish appearance is similar to porcelain enamel, which has a smooth feeling when touched by hand, and is mainly white paint.

Due to the use of scraping construction, the coating film is hard and dense, and the base has a certain adhesion, generally will not bulge, blistering, if it is coated with the appropriate covering agent, pollution resistance and other properties are improved, the coating film of this kind of coating is thicker, not water-resistant, the performance is poor, the construction is more troublesome, the color is single, and the decoration is general.

In addition, melamine paint can also add a variety of fuels, so that the painted wall presents a variety of colors, however, in general, it is best to be white, one is not to add any pigments, the cost is the lowest, the second is that the white wall is the brightest, people will be very comfortable to live in immediately, and there is another point, that is, light blue, pink, light yellow these colors of the wall, at the beginning, it will look quite beautiful, but after a long time, the wall will look very dilapidated, and the white wall will never go out of style.

Because he has the knowledge of making melamine paint in his heart, Li An knows what to do after a little thought, and on the boat, there is a special laboratory, which has Li An brought various experimental materials from Chang'an City, such as beakers, measuring cups, alcohol lamps, and all these experimental equipment.

Li An experimented patiently little by little according to his own memory, and soon made a huge breakthrough, and the raw materials required for various melamine coatings such as gray calcium powder and light calcium carbonate were all studied one by one.

In the end, Ang Lee mixed all these materials together according to the required proportions, and fully stirred them well, and finally made the first Datang version of melamine paint.

There is only one bucket of this melamine paint, and at most it can only paint one wall, and Li An does not want to paint the wall for the time being, after all, there is no reference that can be compared, he has to go to the first street to see the decoration of the merchants, in the absence of lime materials, how do these merchants deal with the interior walls of the house?

With a small number of subordinates, Ang Lee went to First Street and walked into a building that was busy decorating.

The person who rented this floor was a slightly chubby businessman, and when he saw Li An coming in, he hurriedly bent down and stepped forward to say hello.

"Li Shilang." The fat merchant smiled from ear to ear.

Li Ang didn't respond, just nodded slightly, and then began to seriously appreciate the decoration in the room.

The rough walls of the room are brick sides and cement gaps, very rough and very dark, if not decorated, it will be too ugly, and the decoration strategy adopted by this businessman is wood decoration, that is, laying a layer of wood on the surface of the wall, and it is a single-sided polished plank, after the laying is completed, and then painted on the board, so as to make the whole room look more luxurious.

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

Of course, it is better to lay tiles, but the price of tiles is too high, in the era of Datang, ceramic tiles have just been studied, only in Datang, there are no workshops that produce tiles overseas, buy from Datang, and the transportation cost alone can scare people to death, and I am afraid that this boss has never heard of such a thing as tiles.
