high polished alumina ceramic substrate spacers washers boards supplier
Ceramic Plate:
Ceramic plates are extremely weather resistant, and they have no effect on the surface and substrate, whether it is sunlight, rain (even acid rain) or moisture. UV resistance and color stability are fully up to international gray level 4-5. Similarly, large or rapid temperature changes will not affect the properties and appearance of the material. The reasonable combination of bending strength and elasticity makes the ceramic plate have high impact strength. The dense material surface makes it difficult for dust to adhere, making it easier to clean. The ceramic plate has excellent fire resistance properties, it does not melt, drip or explode, and it can remain stable for a long time. The ceramic plates are easy to maintain and require no paint or protective finish on the surface and cutting edges.
Properties
1 the impact resistance - its structure, the panel has a strong resistance, this feature is based on the BSEN438-2/91 sports sphere sag test results, and confirmed by daily practical use.
2 resistance to scratching - special surface structure, so that the ceramic plate has scratch resistance, even if it is affected by various hard objects, it can maintain the shape without damage for a long time.
3 wear-resistant - BSEN438-2/91 test, confirmed that the ceramic plate has a strong wear resistance, suitable for heavy objects placed or need frequent cleaning.
4 easy to clean - tight non-permeable surface, so that dust is not easy to adhere to it, so the product can be easily cleaned with the relevant solvent, without any impact on the color.
5. Moisture resistance - The water absorption of ceramic plates can be comparable to that of glass, so it will not be affected by weather changes and moisture, nor will it be spoiled or moldy.
6 anti-UV - ceramic plate's UV protection performance and panel color stability have reached the international standard JS0105A02, so the ceramic plate is not affected by weather changes, whether it is sun and rain, or temperature changes, ceramic The core and appearance of the board will not change.
7 Fire resistance - According to the BSEN438-2/91 test, the surface of the ceramic plate has a strong protective ability against burning cigarettes. The material is flame retardant, the panel does not melt, and the properties are maintained for a long time.
8 anti-static - according to DIN51953 and DIN53482, ceramic plates have been proven to be anti-static materials, which makes the panel very suitable for dust-free areas, optical industry and computer industry.
9 chemical corrosion resistance - ceramic plates have strong chemical resistance characteristics, such as: acid, oxidation, toluene and similar substances. Ceramic plates also prevent the erosion of disinfectants, chemical cleaners and food juices and dyes. They do not affect the properties of the ceramic plate or the surface.
