70 Grit Aluminum Oxide Blast Media Taiwan

PVB 1200 grit aluminum oxide grinding wheel has poor heat resistance and wear resistance. If it is used together with phenolic resin and alum, it can get high strength and similar performance to phenolic resin grinding tool. Polyaminobismaleimide (PABM) resin: PABM is a prepolymer of maleimide, insoluble in organic solvent, brown fused alumina manufacturer which is polymerized from maleic anhydride and diaminodiphenylmethane.

It is dark blue solid powder with density of 1.28 ~ 1.30g/cm, melting point of 142 ~ 164 ℃, resistant to strong acid and sensitive to strong alkali. The 46 grit aluminum oxide curing process of PABM resin belongs to addition polymerization without by-products, so the abrasives are not easy to foam and the hardening time is shortened. Polyamide resin is mainly used for low density white alumina manufacturing 70m / s high-speed grinding wheel and high-speed cutting wheel.(70 grit aluminum oxide blast media taiwan)

PABM resin has the following characteristics: first, high mechanical strength. The aluminum oxide blast media 60 grit mechanical strength changes with the ratio of maleimide to diaminodiphenylmethane. Second, excellent heat resistance. The heat resistance increases with the increase of Bismaleimide ratio, and the white fused alumina manufacturer mechanical and electrical properties are better in the range of 310 ~ 343 ℃, the decomposition is slow in strong flame, and the long-term use temperature is 180 ~ 250 ℃.

(70 grit aluminum oxide blast media taiwan)Third, excellent curing performance. The white fused alumina highest hardening temperature is 200 ~ 240 ℃. PABM resin has excellent wear resistance, which is mainly used in the manufacture of diamond resin abrasive tools. In the common resin abrasive tools, it is mainly used to manufacture cutting wheel and small pitch (0.25 mm) grinding wheel, white fused alumina suppliers which is characterized by wear resistance, good geometry retention and high quality of the workpiece.

Polyamide has small specific gravity, high impact strength, good oil resistance, wear resistance and white aluminum oxide high tensile strength. However, its thermal deformation temperature is low, its long-term use temperature is below 80 ℃, and its hygroscopicity is large. Therefore, excellent chemical adhesion; the brown fused aluminium oxide mechanical properties of polyamide and the dimensional stability of its products will obviously change with the change of temperature. 

(70 grit aluminum oxide blast media taiwan)Linear polyurethane can be dissolved in acetone, ethyl acetate and other white corundum organic solvents, but not in alcohol, benzene, toluene and other solvents. Unsaturated polyester (UPR) resin: atmospheric pressure molding and no small molecular by-products after curing; water absorption of 0.2% ~ 0.3% white fused alumina price, the unsaturated polyester resin is formed by the condensation of unsaturated binary acid and binary alcohol. 

The characteristics of polyurethane adhesive are: 80 grit aluminum oxide blasting media controllable molecular chain segment to make adhesive with different hardness and elongation; simple bonding process and good operation performance; good wear resistance, water resistance, oil resistance, solvent resistance, chemical resistance, ozone resistance and bacteria resistance; 100 grit aluminum oxide white easy hydrolysis under high temperature and humidity to reduce the bonding strength.(70 grit aluminum oxide blast media taiwan)

The characteristics of the 100 grit aluminum oxide media unsaturated polyester resin are: excellent process performance, room temperature curable, the comprehensive performance of the cured resin is good, its mechanical properties are slightly lower than that of epoxy resin, but better than phenolic resin; for various metals and Nonmetal materials have good adhesion, brown fused aluminum oxide suppliers high transparency, good acid and alkali resistance, low price and many varieties.
