Yuan Lei tells you | The use of glass powder

 

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.

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

2024-06-12


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

2024-06-04


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

2024-05-21


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.
