Many of the properties of coatings depend mainly on:

The first type is low-grade water-soluble coatings, which are made by dissolving polyvinyl alcohol in water and adding pigments and other additives to it. In order to improve its performance and reduce costs, a variety of ways have been taken, there are many grades, the main products are interior wall coatings. The disadvantage of this coating is that it is not resistant to water and alkali, and the coating is easy to peel off after being wet, and it is a low-grade interior wall coating, which is suitable for general interior wall decoration.

This kind of coating has the advantages of cheap, non-toxic, odorless and convenient construction. Dry wipe off the powder, because its film-forming material is water-soluble, so after scrubbing with a damp cloth, there are always some traces, durability is not good, easy to yellowing and discoloration, but its cheap, construction is also very convenient, the current consumption is still the largest, accounting for about 50% of the market, mostly for the low-end room or temporary room interior wall decoration selection.

The second type is latex paint, which is a kind of water as the medium, acrylates, styrene-acrylate copolymers, vinyl acetate polymers as the film-forming substances, and is made by adding a variety of auxiliary components, the film-forming material is insoluble in water, the water resistance and weather resistance of the coating film are greatly improved than the first category, and there are no traces after wet scrubbing, and there are different decorative types such as flat light and high gloss. Due to the fact that it is currently less colorful, the decorative effect is similar to that of Class 106. In fact, these two types of coatings are not a grade at all, belonging to high-end coatings, although the most expensive, but because of its excellent performance and decorative effect, it occupies an increasing market share.

A good latex coating layer has good resistance to water, alkali and scrubbing, and the coating will never peel off after being wet. Generally speaking, (under the same pigment, volume and concentration conditions), styrene acrylic latex paint has better water, alkali resistance and scrub resistance than ethylene propylene latex paint, and ethylene propylene latex paint is better than polyvinyl acetate latex paint (commonly known as latex paint).

The third type is the colorful paint that is very popular at present, the film-forming substance of the coating is nitrocellulose, which is dispersed in the water phase in the form of oil-in-water, and a variety of color patterns can be formed by spraying.

Many characteristics around the vain mainly depend on the serious high school to do well, thinking that this school is still relatively good, so it should be relatively good, to be able to be very good some time ago.

There are many kinds of academic words in my studies, mainly depending on your own personal heartfelt words.

The correct statement about the performance of the coating is as follows:1Color Stability:

The color stability of coatings is often described in terms of lightfastness and fading resistance. This refers to whether the coating will change color or fade after exposure to light or long-term use. 2.

Abrasion resistance: The abrasion resistance of a coating describes its ability to resist physical wear and tear such as scratches, friction, impacts. This performance is typically evaluated according to a series of standard test methods.

3.Corrosion resistance: The corrosion resistance of a coating refers to its ability to remain intact when exposed to various chemicals, gases, or water.

This performance is typically evaluated by standard tests that simulate real-world environments. 4.Adhesion:

The adhesion of a coating describes its ability to adhere to the surface of the substrate. This performance is usually evaluated by different types of peel tests. 5.

The method of use regarding the performance of the coating is as follows:1Choose the right paint for your needs:

Different coatings have different properties, so the application area and the required properties need to be considered when choosing a coating. For example, coatings used on exterior walls need to be highly resistant to weathering and corrosion, while coatings used indoors need to be environmentally friendly. 2.

Construction according to the manufacturer's recommended construction conditions: each type of coating has specific construction conditions and methods, and the application according to the manufacturer's recommended methods and construction requirements can ensure that the coating can play the best performance. For example, it is necessary to control the thickness, temperature, and humidity conditions of the paint Q2 during construction

The phenomenon of tears encountered by the construction master during the construction process is about the performance of the coating.

Kiss, the construction engineer Dakuan Fu encountered the phenomenon of tears during the construction process, which is related to the leveling of the paint Qi imitation shed<>

The performance of the coating is mainly determined by four parts: the performance of the original paint, the construction performance, the performance of the paint film, and the environmental performance.

The performance of the original paint refers to the performance of the coating in the process from production qualification to use, which can also be called the performance of the original state of the coating. The parameters are: appearance, viscosity, density, fineness, and storage stability of the original paint.

Construction performance refers to the construction performance, which refers to the performance and construction parameters of the coating in the construction process. The indicators include workability, coating amount, drying time, recoating time, filling, and sanding.

Paint film performance refers to the performance of the paint film formed after the coating is applied. Includes: 1) Film Appearance, 2) Gloss, 3) Hardness, 4) Adhesion, 5) Transparency, 6) Hiding Power (Solid Color) Yellow Discoloration Resistance, 8) Scratch Resistance, 9) Flexibility, 10) Fullness, 11) Hand Feel.

Environmental performance includes triphenyl content, free TDI content, heavy metals, VOC content, etc

The main properties of interior wall coatings (in addition to environmental protection standards) are: viscosity, density, freeze capacity, dosage, leveling, surface drying time, hiding power, gloss, brush resistance, stain resistance, aging resistance, etc.

Low viscosity and insufficient adhesion, the paint is easy to fall off, the density affects the quality of the coating, the freezing capacity affects the normal construction of the coating at what temperature, the amount of use affects the cost performance, and the sagging phenomenon will occur after the paint with poor leveling is painted, resulting in uneven wall mottling, surface drying time affects the construction progress, hiding power, gloss affects the appearance, and durability affects the service life.

Answer]: a, b, d

According to the properties of the main film-forming substances of coatings: organic coatings, inorganic coatings, and composite coatings.

Answer]: Coatings are mainly composed of film-forming substances, fillers, pigments, additives and solvents.

Film-forming substance: The function of film-forming substance is to bond other components of the coating together, and can firmly adhere to the surface of the base cleaning layer to form a continuous uniform and tough protective film (also known as coating film). The properties of the film-forming substances not only directly determine the hardness, flexibility, water resistance, corrosion resistance, etc. of the coating film, but also determine the workability of the coating and the scope of use of the coating.

Therefore, the basic requirements for film-forming substances are: they can be cured to form a film at room temperature; It has good alkali resistance to ensure that the coating can be used on the surface of cement mortar and concrete; It has good water resistance; Strong weather resistance; Abundant resources and inexpensive.

Filler: Filler, also known as physique pigment, is mostly white or colorless, and does not have tinting strength. In addition to the filling effect, the filler can also increase the thickness of the coating film, give the coating film texture, reduce the shrinkage of the coating film, improve the mechanical strength, wear resistance, weather resistance and aging resistance of the coating film, and reduce the cost of the coating.

Pigments: Pigments, also known as coloring pigments, are mainly used to make the coating film have a certain hiding power and various colors required.

Additives: Additives are auxiliary materials for coatings, the amount is very small, but it can significantly improve the performance of coatings, especially for the film-forming process of film-forming substances and the durability of the coating film plays a very important role.

Water and solvent: water and solvent are dispersion medium, solvent is also known as diluent, the main function is to disperse various raw materials to form a uniform viscous liquid answer, and at the same time can adjust the viscosity of the coating, so that it is convenient for coating construction, which is conducive to improving some properties of the coating film. On the other hand, in the film-forming process, the coating relies on the evaporation of water or solvent to gradually dry and harden the coating, and finally form a continuous and homogeneous coating film.
