70 Grit Aluminum Oxide Blast Media Wholesale

The composite brown fused alumina mortar material is coated on the severely abraded parts to improve the impact and wear resistance of the matrix, prolong its service life and increase the power generation efficiency of the hydropower plant. The arc fused alumina invention improves the defect of poor anti cavitation performance of the existing coating in the application of water turbine.

The product has the characteristics of non initiation, non pulverization and non cracking in the application process. Epoxy resin and 650 PPTA resin play the role of silicon carbide companies bonding; polyurethane improves the anti cavitation performance of materials; amino crosslinker and cyclohexanone enhance the cross-linking degree of epoxy resin; synthetic corundum (also known as brown corundum) is mainly used to ensure the anti abrasion performance of materials; auxiliary agent as filler is mainly used to enhance the flexibility of materials.


The main chemical composition of brown corundum is Al203, with the content of 94.5% - 97%. In addition, it contains a small amount of Fe, Si, Ti, etc. Brown corundum is characterized by high purity, good crystallization, strong fluidity, low coefficient of linear expansion and corrosion resistance. Because of its high hardness and good toughness, fused alumina is often used as grinding material, and is one of the most basic abrasives.


Epoxy resin refers to the polymer compound containing epoxy group in molecular structure, silicon carbide price which is collectively called epoxy resin. The cured epoxy resin has good physical and chemical properties. It has excellent bonding strength to the surface of metal and non-metal materials, emery abrasive good dielectric properties, small variable shrinkage, good dimensional stability, high hardness, good flexibility, alkali and most soluble.


The agent is stable, so it is widely used in various departments of national defense and national economy for brown aluminum oxide pouring, impregnation, laminating, adhesive, coating and other purposes. Poly (phthalamide) resin is a kind of chemical raw material with excellent performance and wide application. According to its properties, it can be divided into two categories: black alumina non reactive or neutral poly (phthalamide) and reactive poly (phthalamide).


Neutral PPTA is mainly used in the production of ink, green carborundum thermosetting binder and coating, reactive PPTA is used in the curing agent of epoxy resin, and used in thermosetting surface coating, binder, lining material, tank sealing and molding resin. 650 PPTA resin is a reactive PPTA resin. The corundum white reactive PPTA resin further reacts and is used as curing agent of epoxy resin, resulting in extensive cross-linking to become thermosetting resin.


It has the advantages of simple brown aluminium oxide construction process, not strict construction conditions, and the coating thickness can be determined according to the wear and cavitation conditions. When it is used as curing agent, it has the advantages of high randomness, innocuity, room temperature curing, softness and embrittlement, etc. it can make epoxy resin have excellent adhesion, flexibility, toughness, 60 grit aluminum oxide chemical resistance, moisture resistance and surface finish.
