Heat insulation and preservation cotton
- Commodity name： Heat insulation and preservation cotton
- 产品描述
-
Thermal heat insulation cotton is a fibrous regenerated mineral organization with natural rock and are as the raw material through high temperature and high pressure. Its form is similar to "wool", so it is called "rock wool",which is a common heat preservation material in industry.
Characteristic
● Combustion performance: the combustion performance of rock wool and slag wool products mainly depends on the content of combustible adhesive inside, rock wool and slag wool belong to inorganic mineral fiber,which are incombustible, when being processed, there's need of adding organic adhesive or additions which would have certain effect on the combustion performance of products.● Heat insulation: good heat insulation is the basic property of rock wool and slag wool products, under the condition of normal temperature(about 25℃), the heat conductivity of rock wool is about 0.03～.047W/(mok).
● Sound insulation: rock wool and slag wool products have good sound insulation and sound absorption performance, the sound absorption mechanism is that it has porous structure, when the sound wave goes through, friction would be generated for the influence of flow resistance, then part of the sound energy would be absorbed by the fiber, and thus obstacle the transformation of the sound wave.Material Specifications Technical characteristics Unit Technical indicators The reference appendix Heat conductivity coefficient w/m.k 0.036-0.048 Density kg/m³ 100-250±15% Fiber diameter micrometer 4-7 Could produce as needed Shot content % ≤12(0.25m以上) Working temperature ℃ 650 Acidity coefficient SiO₂+Al₂O/CaO+Mgo 1.3-1.5
