Yuan Lei Small Class | Do you know the difference between paint and paint?



What is paint?


Coating refers to a liquid or powder material, it can be coated on the surface of the object through a specific construction process, after drying and curing to form a firm adhesion, with a certain strength, continuous solid coating film, the coated object has protection, decoration or other special functions. There are many kinds of coatings and very wide uses. It plays an important role in the national economy and people's life. The average annual use of paint is one of the important indicators of a country's living standards.


What is the difference between paint and paint?


In our country, it is generally believed that the paint is water-based paint, which is used to brush the surface of buildings, and the paint is used to brush wood and metal. In fact, this is a wrong understanding. Coatings include paint, which can be divided into water-based paint and oil-based paint. With the development of petrochemical industry, chemical products emerge in an endless stream, modern paint has been out of the traditional production of paint with oil, more and more paint products through chemical synthesis preparation, paint types, the use of more and more widely. So the difference between them is that paint is a kind of paint. The meaning of paint is broader.


What are the general functions of coatings?

Decorative: The color, texture, polish and gloss levels of the paint provide a decorative effect.

Protection: Different coatings provide protection for different types of substrates. Depending on the paint formulation, the paint provides protection against high humidity, chemicals, oils, corrosion, algae growth and wear.


Special functions: coatings can also be formulated for special purposes. For example, fluorescent paint for signs, other flame retardant paint, anti-condensation paint and electrophoretic paint.



What are the general properties of coatings?


The performance of the coating can be divided into: the appearance of the coating open cans, low temperature freeze-thaw.

The construction method and performance of the coating: brush coating, roller coating, spraying, and construction feel leveling performance, etc.

Film appearance: such as gloss, fullness, color, delicate.

Drying time: surface drying time, hard work time, recoating time and maintenance period.

Adhesion: Adhesion to the substrate or to the old paint film.

Covering power: whether to cover the bottom after normal brushing times.

Mechanical: hardness, impact, flexibility.

Resistance: anti-ultraviolet, anti-chemical, anti-wear, anti-water alkali, anti-mold algae, etc.

Persistence: whether it has long-term light and color retention.

Storage stability: sedimentation tendency, viscosity stability, etc.

Yuan Lei's Little Knowledge | Performance Requirements and Types of Fillers for Coatings


Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.

Yuan Lei's Little Knowledge | Application Effects of Different Mineral Powder Materials in Coatings


In architectural coatings, commonly used mineral materials include barium sulfate, calcium carbonate, kaolin, mica powder, talc powder, quartz powder, silica micro powder, transparent powder, glass powder, wollastonite powder, etc. Reasonable application of various mineral materials can effectively improve or enhance the performance of coatings. Let's take a look at the application of different mineral materials in coatings.

Yuan Lei's Little Knowledge | Characteristics of Mineral Materials


Mineral materials refer to the material products obtained by processing and transforming natural minerals (mainly non-metallic minerals) or rocks as the main raw materials, or minerals or rocks that can be directly used as materials and aim to utilize their main physical and chemical properties. This meaning mainly includes the following four aspects: first, natural minerals and rocks that can be directly utilized or processed to be utilized; Secondly, finished or semi-finished materials made mainly from natural non-metallic minerals and rocks through physical and chemical reactions; Thirdly, artificially synthesized minerals or rocks; Fourthly, the direct utilization targets of these materials are mainly their own physical or chemical properties, not limited to individual chemical elements.
