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 coating solvent does not constitute a coating film and should not 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.

Some modern coatings have been developed and applied - some can dissolve or disperse film-forming substances into liquid state.

Moreover, compounds that can chemically react with film-forming substances to form new substances and remain in the paint film during the construction and film-forming process are called reactive agents or reactive diluents.

However, some of the solvents are added during the manufacture of the paint, 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 adjuvant, also known as the auxiliary material component of the coating, but it cannot form the 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 film.

Different types of coatings require the use of additives with different effects, even for the same type of coatings.

Due to the different purposes, methods or performance requirements of its use, different auxiliaries need to be used.

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

Jenny nodded thoughtfully, and asked 2.6, \"Are those things painted on the wall before?\"

\"It's not that kind, the color that survives is not durable 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, but even when the sun is relatively strong, the color of the wall will be faded.

This color is pure natural, and naturally the color is not long-lasting, so Liu Feng has to re-develop the paint.

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

\"I see, can't paint really change the color of the house?\" Jenny asked curiously.

\"You'll know then, you can paint your house too!\" Liu Feng smiled.

Jenny nodded heavily and said with a smile, \"Then I'm looking forward to it, I'm going to get some paint too.\"

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

\"What color? Does the paint come in many colors?\" 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, and kept blinking her green eyes, thinking, \"I think....I want green.\"

The Elf Princess said without hesitation that she is starting 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, the first thing that flashes in my mind is green.

She wished the whole room was green so it looked 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 she would feel very bad every time she saw green.

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 laughed until her eyes narrowed.

She looked down at her black hair and began to miss her green hair a little.

However, the top of her head is now a little green, and it is starting to grow out slowly.

\"Yes, the paint is green, and green is also 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. The variety of colors is endless and colorful, but there is a certain inner connection 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 the various wavelengths emitted by the surface of the object to the human eye, which 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 that is 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 the secondary color, you can get

\"Saturation\"Different colors.

In the same way, adding different components of black can get various colors with different \"lightness\".

There are also complementary colors added to the complex color will make the color darker, or even become gray or black, which is the relationship between toning, fineness and complementary colors.

In short, the color is also a very deep problem, and you can easily call out another color.

And there are a variety of colors, brightness and darkness can be adjusted according to the color.

Jenny's green eyes widened, and she said in surprise, \"Is there a lot of colors? It's complicated, right?

The Elf Princess was a little surprised. She was painting, and naturally she knew a lot of colors, but she never thought that there were also a lot of paint colors.

\"Like your painting, it's not complicated at all, just add two colors to get another color.\"Liu Feng explained.

\"I see, like yellow and blue equals green, yellow plus red equals orange, red plus blue equals purple, red plus white equals pink, etc?" Jenny asked.

- When it comes to the color fairy princess, she is very excited, and she is still very interested in drawing things.

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

- At first, the fairy princess still didn't know anything, but when it comes to painting, she understands everything.

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