Abstract
Waste rock wool is produced through extrusion and shearing into grains, which are first mixed with cement, gypsum powder or other adhesive material and then adsorbed in certain amount of water to form a layer of enclosing film on the surface. Rock wool grains thus produced may be used as building material. Through the reuse of waste rock wool, the present invention can solve the problem that waste rock wool consumes field and pollutes environment.
Description
The present invention relates to the treatment process of waste rock wool.
Asbestos product is that rock is become magma, is processed to form bulk cotton shape, then sprays a kind of Industrial products made from agglutinates such as resol setting again through high speed centrifugation again through high temperature melting.It is one of material of construction important in the building industry.Asbestos product is processed to behind the sheet material of various sizes can remaining a large amount of waste, also is waste rock wool, because what utility value they have not had, thereby discarded on one side by people, this measure has not only taken a large amount of places, but also has caused the serious environmental pollution.
The purpose of this invention is to provide a kind of method of handling waste rock wool, utilize this method people these waste rock wools can be used again, solve on the one hand and taken in a large number and environmental pollution problems owing to waste rock wool is dropped the place of causing, another side also can be turned waste into wealth, and further increases economic efficiency.
The said method of the present invention is such.Use general screw extrusion shears, the similar in fact meat mincer of said its structure of this shears, its inside band screw rod, orifice plate and cutting knife.Said waste rock wool is put in the screw extrusion shears, under the extruding of screw rod, waste rock wool is extruded and is sheared into particulate state from orifice plate, then, agglutinates such as these particles and cement or terra alba are carried out dried playing the part of, then, allow these particles adsorb a certain amount of moisture content again, make the rock wool particle so that these particulate surfaces form one deck closing membrane.These rock wool particles can be made multiple construction material and use, and as mixing with cement, sand, can make light wall brick or heat-insulating roof board after extrusion molding, mix can do top ceiling etc. after the agglutinate extrusion moldings such as gypsum.
The method of processing waste rock wool provided by the invention can be processed into useful material of construction to waste rock wool, and it not only can solve waste rock wool and go out of use and take the problem of a large amount of places, serious environment pollution, and it also can improve economic benefit of enterprises further.In addition, this method is also simple, reduced investment, the convenient popularization.
Claims (1)
- A kind of method of handling waste rock wool, it is characterized in that waste rock wool is put into the screw extrusion shears to be pushed, be extruded and orifice plate by this shears when extruding, again it cut into particulate state at waste rock wool, then, agglutinates such as these particles and cement or terra alba are carried out dried playing the part of, then, allow these particles adsorb a certain amount of moisture content again so that these particle surfaces form one deck closing membrane.
