Product Overview
Description
China Manufacturer high quality Heat Insulation Glass Growing Cubes Hydroponic Rock Mineral Wool Felt material Supplier
OPERFECT TM rock stone wool products are made from natural rock such as basalt and dolo-
mite. The natural rock is melted into melts in cupola at a high temperature about 1500°C.
And the melts lava is then pour to high speed spinners through which the melts get into
fibers. After that, fibers are collected together to form the original wool mat through nega-
tive 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 rock stone wool board, rock stone wool blanket, rock stone wool pipe
section, hydroponic cube, rock stone wool strip etc with different usage.
