Use of glass powder

Guangdong Yuanlei Powder Co., Ltd.

★Product Features★


      Glass powder is very strange to many people. It is mainly used in furniture wood paint and industrial paint in the coating field. The advantages of glass powder are mainly concentrated in the paint film, ① high transparency ② high hardness ③ strong scratch resistance ④ high temperature resistance. Corrosion resistant.

The refractive index of glass powder is better, and it can be mixed with paint to improve the transparency of paint, especially furniture paint. Moreover, even if the amount of glass powder added reaches 20%, it will not affect the performance of the coating, and it can be more resistant to scratches. The increased glass powder will not increase the viscosity of the coating and will not affect the brushing. It also has the effect of yellowing resistance, high temperature resistance, weather resistance, UV resistance and natural powdering resistance, and stable PH value. Its strength is higher, so that the wear resistance and folding resistance of the coating are also improved.

Glass powder is made of pollution-free raw materials, through low-temperature processing and multi-stage screening, the powder particle size distribution.The narrowest cumulative peak. This result also makes the stirring simple, with a general dispersing machine can be dispersed and then used in the coating to stir evenly.

★Application of glass powder★


1. When glass powder is used for matte resin, it can reduce the proportion of matte powder.

2. The addition amount is about 3%-5%. In order to ensure transparency,Bright paint can add about 5%, while color paint can add about6%-12% of the amount.

3. In order to avoid particles in the use of glass powder, 1% can be addedDispersant, dispersion speed should not be too fast, otherwise the color will turn yellow and black, affecting the brushing effect.

Difficulties in practical application

1. It is difficult to prevent sinking. The density of glass powder is greater than that of paint, and when diluted, it will easily settle at the bottom of the paint. To prevent this situation, it is necessary to adopt a combination of horizontal and vertical anti-sedimentation principle, which can make the paint not appear obvious sedimentation for a period of time after dilution, even if there is stratification, it can be used only by stirring.

2. The recoatability is difficult to control. Glass powder is added to the coating mainly for its transparency and scratch resistance. From the perspective of glass powder alone, the hand feeling of the paint film is not very good, so wax powder or hand feeling additives are generally used in the formula. If wax powder and additives are not properly selected, their recoatability will be affected.

Different applications and specifications of washed kaolin and calcined kaolin


Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.

Source Lei gas barium sulfate ten uses


Barium sulfate is based on barite as the main raw material, through beneficiation, ore washing, crushing and other processes. Barium sulfate has a hardness of 3~3.5 (Mohs) and a specific gravity of 4.3~4.7. It has the characteristics of high specific gravity, low hardness and brittleness. Barite is almost insoluble in water, ethanol and acid, soluble in hot concentrated sulfuric acid. With the development of some high-performance barium sulfate products, the application field of barium sulfate is constantly expanding.

Yuan Lei's Little Knowledge | Talcum Powder Classification and Use


The main component of talc is hydrated magnesium silicate, which is monoclinic. The crystals are false hexagonal or rhombohedral flakes. Ores are usually dense massive, leaf-like, radial, fibrous aggregates. Colorless transparent or white, but with a small amount of impurities and light green, light yellow, light brown, light red and even black; cleavage surface was pearl luster. Soft, Mohs hardness 1-1.5, specific gravity 2.7-2.8.
