Production: Rock Wool are made from natural rock such as basalt and dolomite. The natural rock are melted into melts in cupola at a very high temperature about 1500℃. And the melts lava is then pour to high speed spinners through which the melts get into fibers. At the same time, the phenolic binder containing silicon and mineral oil etc are sprayed onto the surface of each fiber homogeneously. The just fiberized fibers are collected together to form the original wool mat through negative pressure resulted from suction. The original wool mats then pass through pendulum, crimping and pressing process, get into the curing oven through which the wool mats are cured and shape up to different kinds of products such as board, mat and pipe section etc with different usage.

Usage:  Rock Wool are widely used in public, commercial and residential buildings as well as industrial plants, for applications such as roofing, external wall, partition wall and floating floor to provide fire protection, thermal insulation, acoustic control and condensation control.

Rock wool board is made of select fine basalt as the major materials which is pulled into about 7μ non-continuous fibers after melted by adopting advanced international four-roller centrifugal cotton-making procedures and adding a certain of adhesives, dust laying oil and water repellent into rock wool fibers. It can be made into products series with different density according to various uses through the technology of sedimentation, solidify, cutting and etc.
