Our company rock woolis a selection of basalt,Dolomite as main raw materials,such as cooperate with ultra-low sulfur coke and oxygen enrichment,the application in high temperature(1450 degrees)melt into solution,cupola mouth solution and flows into four rollers centrifuge, high-speed centrifugal into fiber,at the same time into a certain amount of binder,dust,oil,hate water under the negative pressure in the lead, such as unifom cotton drum surface adsorption on set,entered into the catcher belt,then through pendulum,the rock cotton fiber on a conveyor belt into a three-dimensional crinkle machine,the curing furnace pressure curing,curing products again after a sawing machine cut into different specifications and usages of the product,the packaging equipment,packaging,manipulator fold code into a crib.
In response to the national environmental policy,hao and rock wool in the process of production,and actively introduce advanced international environmental protection treatment facilities,the waste gas generated in the production of concentrated discharge after treated with high temperature combustion,reached to the standards for acceptance.
