Activated carbon is a specially treated carbon that heats organic raw materials (fruit shells, coal, wood, etc.) under the condition of isolation from air to reduce non-carbon components (this process is called carbonization), and then reacts with the gas to erode the surface and produce a structure with developed micropores (this process is called activation). Since the activation process is a microscopic process, that is, the surface erosion of a large number of molecular carbides is point-like erosion, so the surface of activated carbon has numerous small pores.阅读更多

Zeolite is mainly volcanic sedimentary rock, because the organic matter in the sedimentary rock is liquefied or vaporized, and the formation of fine holes, and these holes are just the living places of nitrifying bacteria. Zeolite is composed of aluminosilicate and other minerals, and has cation adsorbability.阅读更多

coated sand. The surface of the sand is covered with a solid resin film before molding or core sand.Coated sand is mainly made of high-quality natural quartz sand as raw sand, thermoplastic phenolic resin, ulotropine and reinforcing agent as raw materials. According to the different technical requirements of users, the ratio is appropriately adjusted in terms of curing speed, film removal, fluidity, collapsibility, casting surface finish, storage and so on. It is one of the best modeling materials for cars, tractors and hydraulic parts.阅读更多
