• Good thermal insulation performance • Incombustible material • Sound absorption performance and excellent noise reducing effect • Low moisture absorption rate • Low aging rate • Excellent handling characteristics Main Materials in Centrifugal Blowing Technique for Glass Wool Production: &#***2;Quartz sand: Its main composition is SiO2, content of which is above *0%. &#***3;Feldspar: It can be classified into potash feldspar and albite according to its chemical composition. Chemical composition requirement for feldspar: Al2O3>*5%, SiO2<*0%, Fe2O3<0.3%, R2O>*0%. &#***4;Dolomite: Quality requirement for dolomite: MgO>*0%, CaO<*2%, Fe2O3<0.*5. Dolomite is water-absorbent, so it should be stored in dry places. &#***5;Calcined soda: Quality requirement for calcined soda: Na2CO3>*8%, NaCl<1%,Na2SO4<0.1%,&#****8;Fe2O3<0.1%. &#***6;Borax (Na2B4O7?*0H2O): Quality requirement: B2O3>*5%, Fe2O3<0.*1%, SO**-<0.*2%. &#***7;Limestone: Quality requirement: CaO&#***5;*0%, Fe2O3&#***4;0.*5%. &#***8; Cullet: Broken and non-conforming glass products as well as glass chops made by chilling vitreous fluid in water, whether they are glass scraps produced in production or glass waste rejected in society, all can be used as raw materials for glass.
