Cheap White Alumina Powder Manufacturers China

Hard rubber abrasives are solid solids at room temperature and require high elastic coefficients and 80 grit aluminum oxide blasting media tensile strength. Increasing the amount of sulfur added will increase the hardness of the abrasive. The plasticizing method includes a mechanical plasticizing method. low density white alumina used for other rubber abrasive tools do not need to be processed further and can be directly used for mixing material.

Adjusting the hardness of the 100 grit aluminum oxide media tool can be achieved by adjusting the sulfur-containing filler resin and the softening amount in the binder. Rubber abrasive tools commonly used material range. Control the roll distance between the front and back rolls. After rolling for 3 to 4 minutes, the rubber is uniformly and continuously wrapped on the front rolls to form a smooth, gapless bag. Roller glue. The steel grid amount of the compounding agent.


The white fused alumina raw materials used in the manufacture of rubber abrasive tools are abrasive, rubber and compounding agents. After entering the workshop, the raw materials need to be processed according to the production process and the quality requirements of the abrasive tools before they can be used for mixing. When glass bead blasting media suppliers mechanical plasticizing cannot meet the required plasticity requirements, you must use the thermal oxidation plasticizing method.


For soft and flexible abrasive wheels and white aluminum oxide used for extremely thin wheels, they must be coated with phenolic resin and prepared into resin sand before they can be used for mixing. The process of weighing and holding according to the amount of various materials specified in the market ingredients list (market formula) is the ingredients. The formula of the binder determines the hardness, heat resistance and elasticity of the white fused alumina manufacturer.


Raw rubber processing includes cutting, breaking, plasticizing and other white corundum processing. After plasticizing, the molecular structure of the rubber is damaged to a certain extent, and the long-chain molecules are broken into shorter molecules, the molecular weight is reduced, a degradation reaction occurs, the elasticity is reduced, and the brown fused alumina manufacturer plasticity is increased. Add raw rubber, plastic compound, and accelerator to the two roll gaps of the open mill.


This method repeatedly rolls the raw rubber, so that the raw rubber molecules are broken and squeezed by mechanical force, brown fused alumina price and the molecular chain is broken, that is, degradation occurs, which reduces the elasticity and improves the plasticity. Processing of compounding agents There are many types of compounding agents, with different shapes, such as powder, amorphous and viscous fluid, so the aluminum oxide blast media 60 grit processing methods are also different.


Preparation of coated abrasives. You can also use the thermal oxidation black corundum plasticizing method. This method is to heat the raw rubber in the air to a considerable temperature (at 120 ~ 170 ° C). Temperature), so that the raw rubber molecules react with oxygen in the air to produce oxidation, thereby breaking into smaller molecules, reducing elasticity and improving plasticity. Different forms are often treated by 46 grit aluminum oxide crushing, sieving, drying, and evaporation.


The calculation of the batching amount should be determined according to the capacity of the pink corundum mixer; the amount of the abrasive and the binder should be calculated according to the sand ratio: the amount of raw rubber in the binder should be calculated according to the formula; each of the raw rubber content should be calculated. When 1200 grit aluminum oxide batching, the weighing of various raw materials must be strictly controlled, and the error should not exceed 0.5%.
