Abstract
The invention relates to a simple method for preparing polystyrene granules from waste polystyrene foam. The method comprises the main process flows of: heating the waste polystyrene foam, pressing the heated waste polystyrene foam into flaky matters while the heated waste polystyrene foam is hot, cutting the flaky matters into strips, cutting the strips into granules, and packaging the granules, thereby obtaining the products. The method disclosed by the invention is used for preparing the polystyrene granules, the cost is very low, and a large number of waste polystyrene foam generated by cities can be recovered effectively, so that resources are utilized reasonably, and the pollution caused by wastes is reduced.
Description
Technical field
The present invention relates to a kind of method for preparing granules of polystyrene with the waste polystyrene foam, this preparation method will be cut into grain behind the heating of waste polystyrene foam, pressurization, the slitting again, just obtain the simple and easy method of granules of polystyrene.
Background technology
Serious public hazards that the present invention causes mainly for the waste polystyrene foam and rationally not utilizing, and existing recovery method need to be concentrated, and then reclaims, because the proportion of polystyrene foam is very little, therefore cost of transportation is too high and can't effectively reclaim, thereby has caused serious environmental pollution.
Because the present invention is cut into grain after utilizing the waste polystyrene foam by heating, pressurization, slitting again, can obtain granules of polystyrene, its cheap cost recovery makes it have wide application prospect.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of simple and easy method for preparing granules of polystyrene with the waste polystyrene foam, and this preparation method just obtains granules of polystyrene take the waste polystyrene foam as raw material through simple technical process.
The technical problem to be solved in the present invention is by following solution: a kind of simple and easy method for preparing granules of polystyrene with the waste polystyrene foam is characterized in that: the waste polystyrene foam is heated to 120
0C-160
0C, the pressurization slabbing is cut into strip, is cut into the granular product that namely gets again.
Waste polystyrene foam in above-mentioned a kind of simple and easy method for preparing granules of polystyrene with the waste polystyrene foam refers to: the waste polystyrene foam that wrapping waste polystyrene foam and disposable lunch-box are used etc.
Advantage of the present invention is: 1, prepare the cost of granules of polystyrene with this method very low.2, can effectively reclaim a large amount of waste polystyrene foams that the city produces.3, alleviate the pollution that discarded object causes.
