6.Main characteristics and main use of product
The sepiolite is that one of the rare mineral kinds is rich in the nature the silicate mineral of the magnesium fiber ,it main function BE:Have hot stability Adsorb sex strong ,the anti-salt,anti-acid;The characteristic is No social effects damage No pollution.
The sepiolite is extensive application at the petroleum,chemical engineering,building materials and make a medicine etc.Profession;Since can be a heat preservation dope,can also the filler,catalyst of conduct and actions various chemical engineering;Return can be suspend of various liquid,increase a dence,clarifier and take off color and the soundproof heat preservation deodorization of the house material.For domestic and international produce asbestos,cement,rubber,make to move,rub,seal completely,the heat preservation separate hot,dope,spinning,adsorbent,check burnt etc.Product of the business enter prise brought good opportunity.
