Aluminium Oxide Grit 24 Mesh Wholesale Taiwan

For some rubber abrasives with certain characteristics, in order to enhance the adhesion between the aluminium oxide blasting grit particles and the bonding agent, an intermediate layer material (such as phenolic resin) needs to be coated on the surface of the abrasive particles to improve the strength and durability of the white alumina powder tools. This treated abrasive is called "resin sand".

In the technical production of rubber abrasives, artificial corundum have a great impact on rubber performance, for example: the impact of different types of abrasives on the operating performance of raw rubber. Influence of performance (such as strength, durability, surface burns, etc.). In manufacturing methods, roll forming and compression forming are the main methods. The effect of different alumina abrasive content on the performance of abrasive tools.


For styrene-butadiene rubber, aluminum oxide blasting abrasive adheres better to raw rubber than white corundum; the effect of different quantities of abrasives on raw rubber operation performance. When the content of the abrasive in the raw rubber is large, the rubber is brittle, easy to break and break, and it is difficult to form tablets, but the aluminum oxide abrasive media rough size is stable, the vulcanization is not easy to deform, and it is easy to grind when making loose materials.


Generally speaking, as the aluminum oxide abrasive blasting grit content increases, the binder content will decrease accordingly, so the strength of the abrasive tool will be reduced, and the quality and durability of the machined surface will be poor, but the cutting force is strong and it is not easy to burn the black aluminum oxide media workpiece; and vice versa. Generally speaking, rubbers with the same structure have a small molecular weight, and the smaller the elasticity, the greater the plasticity.


According to different brown fused alumina processing procedures of latex, it can usually be divided into: tobacco flake gum, corrugated flake gum and air-dried film. Among them, tobacco sheet rubber is the most widely used variety of rubber abrasives, and is also the most representative of natural rubber. The density of natural rubber is between 0.9 ~ 0.95g / cm '. There is no fixed melting point, and temperature changes have a greater impact on aluminum oxide 40 grit elasticity.


Styrene butadiene rubber is an irregular elastomer composed of cis-, trans-1,2 structure, etc. Styrene-butadiene rubber is relatively stable and has little physical and brown aluminum oxide chemical changes during storage. SBR can be added with more fillers, and the aging reaction rate is slower even at higher temperatures; alumina grit which has less impact on physical and mechanical properties. It is suitable for manufacturing rubber products with low rubber content. 


The styrene-butadiene rubber with antioxidants can be stored for several years in the brown aluminium oxide dark, but will occur under the combination of light, heat, oxygen and ozone. Physical and chemical changes, but the oxidation is slower than natural rubber, the aging effect of light on styrene-butadiene rubber is not obvious, and the aluminum oxide 220 grit abrasive effect of ozone on butylaniline is more sensitive than that of natural rubber. Worse than natural rubber.


The tear strength is only half that of natural rubber and the fused aluminum oxide resistance to flex cracking is poor. Elasticity is lower than natural rubber. Generally, styrene-butadiene rubber has about twice the heat generation of natural rubber; cold resistance is worse than natural rubber; heat resistance, oil resistance, wear resistance, and aging resistance are better than natural rubber; It is more difficult to roll and extrude; synthetic corundum price without crystallinity.
