 Superfine Aluminum Hydroxide Superfine Aluminum Hydroxide

 Physical and chemical properties:

Superfine Aluminum hydroxide, a kind of white loose powder, has high whiteness and low bulk density. It is stable at room temperature and turned into alumina under being heated, decomposed and dehydrated. This product is different from other flame retardant material, because it does not produce toxic and corrosive gas. Heat absorption and water vapor release under heat make it a good one with flame retardant and self-extinguishing performance. Thus, to add this aluminum hydroxide in the advanced composite materials such as plastic, rubber, will make products have flame retardant and smoke abatement effect, and enhance its resistance to electricity leakage, arc and abrasion.

 TM-WA Series White Fused Alumina Abrasive TM-WA Series White Fused Alumina Abrasive

 Taking commercial alumina as raw material, white fused alumina is made by electric arc furnace melting. After it is crushed, ground and classified, fused white alumina abrasive of different size can be produced. Its color is white.

Features:

It has high hardness, strong grinding force and wide application. Micro hardness can reach 2200~2300kg/mm2.

Applications:

1)    Decorative material polishing: Abrasive tools made of this abrasive material are suitable to grind high-carbon steel, high-speed steel and other thin wall parts.

2)    Polishing material: Abrasive powder is directly used in polishing materials and other precision casting sand.

3)    Spraying material: It is used in plasma spraying.

4)    Special ceramics and superior refractory products

Models:

W0.5~W63, 4#~240#, etc.

 TM-WCA Series α-Alumina for Monocrystalline Silicon TM-WCA Series α-Alumina for Monocrystalline Silicon

 This abrasive material is developed by our company specially for the electronics industry. It uses commercial alumina as main raw material and adopts special mineralizing agent. After high temperature calcination, it will turn into tabular alumina with grain crystal of a certain thickness-to-diameter ratio. Tabular alumina is ground and strictly classified. The powder color is white. According to the users’ requirements, we can produce this abrasive material with Chinese standard or Japanese JIS standard.  

Features:

Crystal has a plate form and peripheral edge is smooth, which makes it free from scratch. It has characters of narrow particle size distribution, high hardness (Moh’s hardness 9) and strong grinding force. After being ground, the plate has good-quality surface. It can reach the quality level of similar foreign products and replace the imported ones. It is produced exclusively by our company in China. 

Applications :

1)     Electronics industry: Monocrystalline silicon wafer polishing

2)     Electronics industry: crystalline lens polishing

3)     Electronics industry: Aluminum alloy material, like mobile phone shell and stainless steel polishing

4)     Decoration industry: stainless steel tableware and other decorating material polishing

5)     Spraying material: plasma spraying

Models:

Note:

1)    Suspension performance is holding time without settlement after two abrasive materials (our company’s WCA and Japanese Rich Jimmy PWA15) are mixed with suspending liquid in equal proportion.

2)    Grinding rate is measured by grinding 4-inch monocrystalline silicon wafer on the same grinding machine with these two abrasive materials (our company’s WCA and Japanese Rich Jimmy PWA15).

TM-P Series Polishing α-Alumina TM-P Series Polishing α-Alumina

 Features:

It has characters of narrow particle size distribution, high grinding efficiency and good polishing effect. Its grinding efficiency is much better than soft abrasives, like silica. Because of its good particle shape, high smoothness after surface treatment and better polishing effect than white fused alumina, it is widely used to polish aluminum product, steel product, stainless steel, stone, glass, wall and floor tiles, etc. Since it entered the market, it has got praise from the users. It shows its great polishing performance especially in the field of metallic materials, like stainless steel, copper product, etc. and in the glass industry. Among them, TM-P01 and TM-P12 are mainly used to polish stainless steel, which can realize the mirror polishing effect and improve the performance of polishing wax and paste to a new level.
