4a zeolite powder washing raw material white powder 4a zeolite powder industrial grade sewage treatment 4a zeolite powder

4A zeolite powder is a non-toxic, odorless, tasteless, and well-flowing white powder.

Has strong calcium ion exchange ability, no pollution to the environment, is an ideal phosphorus-free detergent, surface adsorption ability is strong, is an ideal adsorbent and drying agent. Also known as Na12[(AlO2)12、(SiO2)12]27H2O, also known as 4A molecular sieve. White solid particles. Present in a reticular structure, containing uniform small pores, pore diameter of 0.42nm, specific surface area of about 600m2/R, insoluble in water and organic solvents, can be dissolved in strong alkali and strong acid. When heated above 800℃, it recrystallizes to form a white wollastonite-like structure. It can absorb water, liquids, gases and unsaturated organic substances. It has the ability to exchange calcium ions, the theoretical exchange ability is 352CaCO3mg/g, usually 290~320mgCaCO3/g, whiteness ≥95%, pH value of 10~11.5, apparent density of 0.3~0.5g/cm3, average particle size of 2μm, particle size distribution ≤4μm accounts for more than 85%. Used as a phosphorus-free detergent, replacing sodium triphosphate; used in petroleum and other industries for gas and liquid drying, dehydration purification, etc., also used as a catalyst and soft water agent.
