Rock wool is originated in Hawaii.It is a kind of minal wool.After a volcanic eruption on the Hawaiian islands, the island's inhabitants found some soft wisps of melted rock on the ground.This is the first human cognition of rock cotton fiber. The production process of rockwool wall insulation simulates the natural process of the Hawaiian volcano eruption. The rockwool wall insulation use high-quality basalt and dolomite etc as main raw materials. After above 1450 ℃ high temperature melting, adopting international advanced four axis centrifuge,the lava was centrifuged into fibers at high speed.At the same time, a certain amount of binder, anti-dust oil and waterproofing agent are put into the material.Then, the fiber is gathered through the cotton collecting machine and collected by a pendulum process (which improves the uniformity of the cotton layer and the binder contained in it. At the same time, the compressive strength and interlayer bonding strength are improved because the fiber is partially vertically distributed due to the slant of the cotton layer) combined with three dimensional cotton-spreading method,the wool insulation is made.Then it is solidified and cut to form products with different specifications and uses such as rockwool roof insulation.
Application of rock wool
In modern society, rock wool thermal insulation has been widely used as a kind of new material in construction, metallurgy, chemical industry, electric power, petroleum, agriculture, machinery, light industry, textile, military industry, transportation, storage and other industries.It is also used in all kinds of buildings such as industrial kilns, boilers, heat exchangers, distillation towers, storage tanks, flue of cold storage tanks, pipes, valves, fans, air conditioners, vehicles and ships. Even the development of modern national defense, aerospace, atomic energy technology are inseparable from this new multi-functional material which is thermal insulating and sound absorpting.
