Product description, Product introduction: Zeolite is a kind of new material, by aqueous alkali or alkaline earth metal aluminum silicate minerals Main Chemical composition of Zeolite are Si02,A1203, H2O and alkaline earth metals, Si02 and A1203 content is about 80%.Physical properties of zeolite: Moh�??s Scale Hardness is from 3.5 to 5.5,density is from 2.1 g/cm3 to 2.5 g/cm3.Zeolite Has good performance of adsorption, cation exchange properties, catalytic properties, heat resistance, acid etc.Zeolite is used as friction material to for stable friction coefficient,and can reduce the cost. It can be used in brake pad drum brake or clutch. The recommended regular consumption of zeolite is from 2% to 8%. The character of Zeolite: Zeolite is the floorboard of the family of zeolite minerals, a frame structure, is a kind of aqueous alkali or alkaline earth metal aluminum silicate minerals. At present our country found more than 10 kinds of natural zeolite,such as clinoptilolite ,mordenite zeolite, alkali ling zeolite and calcium cross,but widely used only clinoptilolite and mordenite zeolite.Zeolite has many function and usage. Zeolite density is small, high foam, good activity, zeolite water of crystallization and the general structure of water (OH) is different, because it as water molecules, the zeolite water under a certain temperature heating, the lattice structure are not destroyed after dehydration, the location of the original molecules there are still gaps, form a lattice structure, sponge with water and gas suction space feature, when the temperature rises, the zeolite cavity that the larger molecules to enter, cooled molecules trapped within the cavity and keep for a long time, until the heat release. The characteristics of zeolite was known as the "boiling". Foreign patent added zeolite in friction material to absorb gaseous and liquid molecules emitted by thermal decomposition to achieve the purpose of reducing thermal annealing Property: SiO2: 65%min A1203: 18% -22% Zeolite content: 60% min grade: 200mesh,325mesh sieving rate: 97%
