GlassWool Production Line

Brief Introduction of Glass Wool
Glass wool is made of natural ores such as quartz sand, dolomite, feldspar,limestone and so on, which are melted into glass fluid by adding in accessoriessuch as calcined soda and borax and then drawn, blownor thrown into very thin fibers by external force under fusing state and now itis a kind of insulation material with excellent characters.

Main Materials toProduce Glass Wool

Item	Description
Quartz sand	Its main composition is SiO2, content of which is more than 90%
Feldspar	It can be classified into potash feldspar albite according to its chemical composition. Al2O3>15%, SiO2<70%, Fe2O3<0.3%, R2O>10%
Dolomite	MgO>20%, CaO<32%, Fe2O3<0.15. Dolomite is water-absorbent, so it should be stored in dry places
Calcined soda	Na2CO3>98%, NaCl<1%, Na2SO4<0.1%, Fe2O3<0.1%
Borax (Na2B4O7.10H2O)	B2O3>35%, Fe2O3<0.01%, Na2SO4<0.02%
Limestone	CaO≥50%, Fe2O3≤0.15%
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

Features of Glass Wool
As a kind of inorganic fiber, glass wool has the following basiccharacteristics:
1. Good thermal insulation performance under both high and low temperature.
2. “Statutory incombustible material” --- it neither burns, nor gives offharmful gas.
3. Uniform resilience force.
4. Excellent sound-absorption performance and noise reducing effect.
5. Low moisture absorption rate under humid conditions.
6. Low coefficient of linear expansion.
7. Low aging rate, being able to maintain the original performance afterlong-time use.
8. Excellent handling characteristics.
