Abstract
A process for reclaiming waste glass wool includes breaking and/or combing the waste glass wool, addition of adhesive, extrusion shaping, heating and drying to obtain regenerated glass wool product.
Description
The present invention relates to a kind of regeneration of material, especially relate to a kind of regeneration method of glass wool.
At present the glass wool goods are widely used in every field such as sound insulation, heat insulation, insulation, but its waste wood does not still have effective reclaiming technology, and have to abandon it as industrial refuse, and contaminate environment.
The purpose of this invention is to provide a kind of production method of the waste mineral wool goods being carried out making after the reclaiming new glass wool goods.
The objective of the invention is to realize in the following way: the waste mineral wool goods are pulverized and/or are combed into fibrous after, add tackiness agent again by extrusion molding, through heating, getting final product after the drying.
The present invention adds tackiness agent and carries out the new glass wool goods of regeneration by pulverizing the waste mineral wool goods, has the minimizing environmental pollution, increases remarkable advantages such as economic benefit.
As specific embodiment of the present invention, earlier the waste mineral wool goods are separated layer by layer, and comb into the above fibrous glass wool of 2mm, use the warm water more than 8 ℃ again, behind the flush away resin, slough when washing resin attached to the moisture content on the glass wool with centrifuging then, its water ratio is dropped to below 30%, add tackiness agent with conventional technology again, after heating, drying, make required repeat glass cotton products.
Preferred as the embodiment of the invention washed the water that resin is used, and its water temperature preferably remains on 70～90 ℃, and the composition of looking the waste mineral wool goods adds proper amount of solvent.
