Chapter 1702

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 film formation during construction 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.

It can be said that there are many colors of paint, and the varieties of colors are endless and colorful, but there are certain internal connections between various colors.

Because each color can be determined by three parameters, namely hue, lightness and saturation.

Color is also a very deep thing, because hue is the characteristic that distinguishes colors from each other.

These characteristics are determined by the chromatographic composition of the light source and the perception of each wavelength emitted by the surface of the object to the human eye, and can distinguish red, yellow, green, blue, purple and other characteristics.

This is still very common, because the colors in nature are ever-changing, but the most basic are red, yellow, and blue, which are called primary colors.

Another color obtained by mixing these three primary colors in different proportions is called a complex color.

Also in the color matching, adding white to dilute the primary color or secondary color, you can get

"Saturation" of different colors.

In the same way, by adding different components of black, various colors with different "brightness" can be obtained.

Adding complementary colors to complex colors will make the color darker, or even gray or black, which is the relationship between toning, fineness and complementary colors.

In short, the color is also a very deep problem, and another color can be called out casually.

And there are all kinds of colors, and the lightness and darkness can be adjusted according to the color.

Jenny widened her green eyes and said in surprise, "Are there many colors? It's complicated, right?

The elf princess was a little surprised. She is a painter, so she naturally knows that there are many colors, but she never thought that there are many colors of paint.

"Just like your painting, it's not complicated at all, you can add another color by adding two colors casually." Liu Feng explained.

"I see, like yellow and blue make green, yellow and red make orange, red and blue make purple, red and white make pink and so on?" Jenny asked.

- When it comes to the color elf princess, she is very excited, and she is still very interested in painting.

After all, painting is her favorite thing to do, and when it comes to this aspect, the elf princess still understands it very well.

- At the beginning, the elf princess still didn't know anything, but when it comes to painting, she knows everything.

"That's right, you don't need to use all the dark green, you can adjust the lightness or darkness, depending on your mood." Liu Feng smiled. Jenny nodded heavily, and replied, "I see, I will decide according to the color."
