Hydropower stations on rivers generally encounter a difficult problem, that is, the serious abrasion of brown fused alumina price to the auxiliary facilities of hydropower stations and hydropower units. A method for anti-abrasion of a composite resin corundum mortar material is performed according to the following steps: An angle grinder or a green silicon carbide sand blasting method is used to derust the easily-abrasive parts of the over-flow parts or the easily-abrasive parts of the auxiliary facilities. 

(cheap 100 grit aluminum oxide white suppliers mexico)Frequently, white fused alumina overcurrent components of hydropower stations, such as impellers, guide vanes, volutes, etc., as well as auxiliary facilities of hydraulic engineering and mining machinery and equipment, such as concrete structures, cause severe abrasion and erosion damage, which greatly reduces the service life of these aluminum oxide abrasive components and even severely damages them. It directly affects the power generation efficiency of hydropower plants.

The purpose of the present invention is to overcome the black corundum deficiencies in the prior art and provide a composite resin diamond mortar, which can improve the impact resistance and abrasion resistance of the matrix, thereby extending its service life, a method for preparing the same, and a method for resisting abrasion. The black silicon carbide composite resin diamond mortar material is applied to the severely abraded parts.(cheap 100 grit aluminum oxide white suppliers mexico)

The purpose of the present invention is achieved as follows: a composite resin white aluminum oxide mortar, characterized in that it comprises the following raw materials prepared by weight: 100 parts of epoxy resin, 30-40 parts of 650 polyphthalamide resin, and polyurethane 15-20 parts, 5 parts of amino crosslinker, 2 parts of cyclohexanone, 7000-8000 parts of aluminum oxide grit, and 5-10 parts of auxiliary. The auxiliary means carbon black or Sudan red.

(cheap 100 grit aluminum oxide white suppliers mexico)Many rivers in China have a large amount of pink corundum sediment and a large amount of sand transported. A method for preparing the composite resin corundum mortar material, characterized in that: the epoxy resin, 650 polyphthalamide resin, polyurethane, amino crosslinker and cyclohexanone are mixed and stirred to form a ring in the above proportion. Oxygen resin colloid, then add garnet abrasive price and mix well, and then add carbon black or Sudan red additives to make composite resin silicon carbide mortar material.

Water removal and polishing treatment; On-site preparation of composite resin white corundum mortar material and bonding primer; the formula of the bonding primer is 100 parts of epoxy resin, 30-40 parts of 650 polyurethane resin and auxiliary 5- 10 parts, mix the epoxy resin and 650 resin according to the ratio and stir well, add the auxiliary agent; Heat the abrasion-prone parts of the over-flow parts or the abrasion-prone parts of the black aluminum oxide blast media auxiliary facilities to 50 ° C.(cheap 100 grit aluminum oxide white suppliers mexico)

First apply the adhesive primer to the silicon carbide abrasive abrasion-prone parts of the over-flow parts or the abrasion-prone parts of the auxiliary facilities, and then Apply composite resin corundum mortar material to the abrasion-prone parts of the over-flow parts or the abrasion-prone parts of the ancillary facilities; Brush or spray the polyurethane material on the surface of the black aluminum oxide abrasive 70 grit coating twice; Insulate and cure 12 In hours, the final anti-abrasive coating is the composite resin corundum mortar material.
