Starting Today, I'll Work as a City Lord.

Before he started to study paint, Liu Feng had been reading books on it.

Those knowledge are so profound that it makes people feel dizzy when they see it, not everyone can understand it.

Because the paint on the earth is mainly composed of four parts: film-forming substances, pigments, solvents, and additives.

The first film-forming substance is the basis of the coating, which plays a decisive role in the performance of the coating and the coating film. It has the function of bonding other components in the coating to form a coating film.

It can be used as a film material in many varieties, and it is the main resin used in the contemporary coating industry on the earth.

Resin is an organic substance that exists in an amorphous state, usually referring to a high molecular polymer.

In the past, natural resins were used as film-forming substances in paints, but synthetic resins are widely used in modern times.

For example, alkyd resin, acrylic resin, chlorinated rubber resin, epoxy resin, etc.

The other pigment is a main component of colored paint (paint).

This kind of pigment makes the coating film show color, so that the coating film has the ability to cover the object to be painted, so as to play its role of decoration and protection.

Another point is the solvent. The solvent can dissolve or disperse the film-forming substances in the paint into a uniform liquid state. This solvent is a substance that facilitates the construction of the film and can volatilize from the paint film to the atmosphere after construction. The upper solvent does not constitute the coating film, nor should it remain in the coating film.

Not only that, in many chemicals, including water, inorganic compounds and organic compounds can be used as solvent components of coatings.

In some modern coatings, some materials that can dissolve or disperse film-forming substances are developed and applied in liquid state.

Moreover, the compound that can chemically react with the film-forming substance to form a new substance and remain in the paint film during the film-forming process is called a reactive agent or a reactive diluent.

However, some solvents are added when the paint is manufactured, not all of them are put in at the beginning, and some are added during the construction of the paint.

The last point is the additive, which is also called the auxiliary material component of the paint, but it cannot form a coating film independently.

It can exist in the coating film as a component of the coating film after the coating film is formed.

The role of additives is to improve the performance of a specific aspect of the coating or coating film.

Different types of coatings require different additives, even for the same type of coating.

Due to the different purposes, methods or performance requirements, different additives need to be used.

A variety of different additives can be used in a coating to play its different roles.

Jenny nodded thoughtfully, and asked 2.6, "Is it the things that were painted on the wall before?"

"It's not that kind. The color that remains doesn't last long and fades easily." Liu Feng explained.

Now the pigments in Chang'an City are also produced by the scientific research department, but the coloring does not last for a long time.

If it rains, it is easy to fade, so it is necessary to complement the color all the time.

Not only is it raining, even when the sun is relatively strong, the color on the wall will be faded.

This kind of color is purely natural, and naturally it does not last long, so Liu Feng has to re-develop the paint.

But the paint should not have too many chemical materials, which is not good for the body, and the natural color retention is not high.

"I see. Does not knowing how to paint really change the color of the house?" Jenny asked curiously.

"You will know when the time comes, your house can also be painted!" Liu Feng smiled.

Jenny nodded heavily, and said with a smile, "Then I'm looking forward to it, and I want to paint."

"What color do you want?" Liu Feng asked.

"What color? Are there many colors of paint?" Jenny's green eyes widened.

"Of course, there are many colors of paint, what color do you want?" Liu Feng asked.

Jenny was a little excited, she kept blinking her green eyes, thinking, "I think... I want green ones."

The elf princess said without hesitation that she began to like this color now.

She didn't like green before, but since she came to the Han Dynasty, she fell in love with green deeply.

Now that the house can be decorated in other colors, green is the first thing that comes to mind.

She wished that the whole room would turn green, so that it would look comfortable.

"Oh? Green? *Liu Feng raised his eyebrows slightly.

He was also a little surprised. He didn't expect the elf princess to accept green now.

You must know that she didn't like green very much before, and every time she saw green, she would feel very bad.

Even depressed, I have been avoiding green all the time, and I don't like my hair very much, so I bought a hat to hide my hair.

"Yeah, I like green very much now." Jenny smiled until her eyes narrowed.

Looking down at her black hair, she began to miss the green hair before.

But now there is a little green on the top of her head, which is slowly growing out.

"Yes, there are green paints, and green is divided into many colors. You can choose according to your mood." Liu Feng said softly.
