Become the city lord from today

Chapter 1961: Advanced paint. (1 more please customize)

"Your Majesty, this is the document for the renovation of the castle."Anli handed over the documents.

The castle in Chang'an City has been preparing for decoration recently, because the castle has never been decorated.

The castle is already very old compared to the tallest building, so it had to be renovated.

Of course, the castle must be lived in It's getting better, it can't be the same as before, and now its status is no longer the same as the previous city lord.

The place where the king lives must be better, otherwise when some people come in the future, they will see that the castle is not very good, and it will still be a bit embarrassing. Therefore, we still need to do a good job in face-saving projects.

"good."Liu Feng nodded, took the document and started to read it.

What was drawn on the document was a diagram of the castle's internal structure. It was very detailed, down to every room."Seven Eight Three" is not just that, The decorations in the room are also drawn, so it can be said that everything is done down to the smallest detail.

"Your Majesty, this paint has also been produced and can be produced within a few days." Enri continued

"Let’s take some and see. Liu Feng said

"Your Majesty, what is paint? What can it be used for?"Jenny asked curiously

"It can be used to change the color in the room and make the room look different. Liu Feng explained.

In fact, paint is a kind of chemical mixture paint that can firmly cover the surface of certain objects. It is mainly used for protection, decoration, marking and other special purposes.

Paint is also a kind of material. This material can be used in different ways. The construction process is applied to the surface of the object to form a solid film that is firmly adhered, has a certain strength and is continuous. The film formed in this way is generally called a coating film, also known as a paint film or coating, and coatings are generally composed of film-forming substances, fillers (colors) It consists of four parts: fillers), solvents, and additives.

Of course, sometimes the ingredients will change slightly according to performance requirements. For example, varnishes do not have pigments and fillers, and powder coatings do not need solvents.

Paints are organic chemical polymer materials, formed The coating film belongs to the polymer compound type.

According to the classification of modern chemical products on earth, the coating belongs to fine chemical products.

"Is it so magical? Jenny's eyes widened and she continued to ask,"Your Majesty, how could there be such a thing?""

This is the first time the elf princess has heard of such a thing, and the first time she has heard of the name.

"It was researched by the Scientific Research Department, you will find out later."Liu Feng explained.

When he was thinking about decorating the castle, he brought paint from the earth.

The ingredients and production methods of the paint were given to the scientific research department, so that they could start researching.

Because not only the castle needs Decoration, new and new urban areas will also be decorated with paint.

Of course, these paints will not use too many chemical materials, because too many chemical materials are bad.

After all, in this era, we cannot use too many unnatural things, so It’s not good for your health.

The paint took a long time to develop, more than half a year.

The reason is to avoid chemical ingredients and to use pure natural ingredients, so that it is safe to live in..

Especially for the castle, what is more important is that it must be purely natural, otherwise he would have used the paint he brought back from the earth.

Because what is important is that it is purely natural, so it is safe to live in, and it tastes good..

Before he started studying paint, Liu Feng had been reading books on this subject.

The knowledge was so profound that it made people feel sleepy. Not everyone could understand it.

Because the earth The paint over there mainly consists of four parts: film-forming substances, pigments, solvents, and additives.

The first film-forming substance is the basis of the paint. It plays a decisive role in the performance of the paint and coating film. It has adhesive properties. It has the function of forming a coating film by combining other components in the coating.

There are many types of substances that can be used as film substances. The contemporary coating industry on the other side of the earth mainly uses resin.

Resin is an organic matter that exists in an amorphous state, usually referring to high Molecular polymer.

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

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

The other pigment is colored A main component of coatings (paints).

This pigment gives the coating film its color and gives the coating film the ability to cover the object being painted, so as to play its decorative and protective role.

Another point is the solvent, which can dissolve the coating The film-forming substances in the film are dissolved or dispersed into a uniform liquid state 0....., this kind of solvent is a substance that facilitates film formation during construction and can volatilize from the paint film to the atmosphere after construction. In principle, solvents do not form a coating film and should not remain in the coating film.

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

Some modern coatings have developed and applied some film-forming substances that can be dissolved or dispersed into a liquid state.

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

However, some solvents are added during the manufacturing of the paint, not all of them are added 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 coating, 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 function of additives is to improve the performance of a specific aspect of the coating or coating film.

Different types of coatings require the use of additives with different functions, even if they are the same type of coating.

Different additives need to be used due to different purposes, methods or performance requirements.

A number of different additives can be used in a coating to exert their different effects.

Jenny nodded thoughtfully and asked 1.4,"Are they those things that were painted on the wall before?"

"Not that kind, the color that remains is not long-lasting and fades easily. Liu Feng explained.

Nowadays, the paints in Chang'an City are also produced by the Scientific Research Department, but the color does not last long.

If it rains, it will fade easily, so you need to replenish the color all the time.

No Just when it rains, even when the sun is relatively strong, the color on the wall will be faded.

This color is purely natural and does not last long, so Liu Feng has to develop new paint.

But paint There should not be too many chemical materials, as this is not good for the body, and the natural color retention is not high.
