asbestos and rock wool ? Next, let’s take a look at the difference between rock wool board and asbestos board !
Asbestos is a natural fibrous siliceous mineral and the only mineral fiber. Asbestos itself is not carcinogenic. What causes carcinogenic is the asbestos fiber that appears after the asbestos quilt is destroyed. Asbestos fiber is as strong as steel wire and will basically not be easily excreted after being inhaled into the lungs. It will slowly deposit in the lungs, eventually causing diffuse pulmonary fibrosis. The main material of
rock wool is basalt stone , which is the result of rapid cooling of underground rock blocks after melting. The loader puts these gravels into a filter for screening. The separated fine particles and large pieces of gravel will be used to make rock wool blocks. These gravels and slag will be placed in a high-temperature furnace and melted into magma . At this time, a high-speed centrifugal machine is used to form filamentous substances. By slowly rotating, all the filaments are bonded together, and the inorganic cotton we need in the early stage is formed.
Then add efficient hydrophobic agents and binders to make it have the effect of preventing moisture penetration and high strength and hardness. The fluffy flake rock wool increases the hardness and density of the inorganic cotton through the pendulum method. After a series of processing, the rock wool is finally formed.
This rock wool thermal insulation material is internationally recognized as a first-class fire-saving material. Its thermal insulation, thermal insulation and sound insulation are also excellent.
rock wool has higher safety performance compared to asbestos.
