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.Werengani zambiri

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.Werengani zambiri

Coral sand is a fragment of coral or shell that consistently releases calcium carbonate and comes in a variety of sizes and sizes. The biggest feature of coral sand is that it is rich in micropores, suitable for the survival of a large number of biochemical bacteria, and can be used as a filter material.Werengani zambiri

Glass microbeads have been developed in recent years as a kind of new material with wide application and special properties. The product is made of borosilicate raw materials by high-tech processing, the particle size is 10-250 microns, the wall thickness is 1-2 microns. The product has the advantages of light weight, low thermal conductivity, high strength, good chemical stability and so on. The surface of the product has the characteristics of oil and water resistance after special treatment, and it is very easy to disperse in the organic material system.Werengani zambiri

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.Werengani zambiri

Non-toxic. Medical stone is a compound mineral or medicinal rock that is non-toxic and harmless to organisms and has certain biological activity. The main chemical composition of medical stone is inorganic silicaluminate. Including SiO2, Al2O3, Fe2O3, FeO, MgO, CaO, K2O, Na2O, TiO2, P2O5, MnO, etc., also contains some of the major elements required by animals, such as: K, Na, Ca, Mg, Cu, Mo and other trace elements and rare earth elements, about 58 kinds of.Werengani zambiri
