Rock wool production line for the raw material requirements are very strict to ensure that the production of rock wool products with excellent performance and quality. The following is the rock wool production line on the raw material requirements of the detailed sub-points indicated and summarized:
First, the main raw materials
1. aluminum silicate fiber
High chemical stability, shall not contain free magnesium oxide and other toxic and harmful substances. Aluminum oxide content should be more than 60% to ensure the performance of the product. The length and diameter of the fiber need to meet the production requirements.
2. Basalt
As one of the main raw materials, the silicate content shall not be less than 45%. It must have good chemical stability and not easy to burn. No toxic and harmful substances and harmful oxidizing substances must be present.
3. Dolomite and limestone
As subsidizing materials, used to adjust the chemical composition and physical properties of rock wool. Dolomite is usually used as a melting agent, and the amount added is usually 0.5% to 4% of the furnace output. Limestone is used to increase the alkalinity of rock wool and improve its fibrillation properties.
