Description

A kind of disintegrating apparatus pulverized for glass fiber reinforced plastics composite material or elastomeric material

Technical field

The utility model relates to processing units field and environmental protection field, particularly relates to a kind of disintegrating apparatus pulverized for glass fiber reinforced plastics composite material or elastomeric material.

Background technology

Glass fiber reinforced plastics composite material is a kind of plastics strengthened by the strongthener such as glass fibre or carbon fiber, because of its intensity height, good toughness, resistance to corruption, resistance to compression, all uses extensively in industry and civilian occasion, it is even possible that be used as gas cylinder equal pressure container. Generally, the indoor use design time limit of glass-reinforced plastic material is 20--30, and the use of the outdoor design time limit only 10--20, actual use is also less than the design time limit. China uses glass reinforced plastic history existing more than 50 year, and the utilization of the materials such as a large amount of retired glass-reinforced plastic materials and glass reinforced plastic production redundancy material and process will be the key subjects of environmental protection from now on, the utilization of resources.

The pulverizing difficulty of glass fiber reinforced plastics composite material and elastomeric material is big all the time, becomes an industry difficult problem. It is generally required to freezing and pulverizing or multi-stage crushing, not only complex process, and efficiency is not high, energy consumption is big. Domestic market there is no the special disintegrating apparatus of glass fiber reinforced plastics composite material or elastomeric material up to now. And the retired every year material such as glass fiber reinforced plastics composite material and waste and used rubber tyre of our country has hundreds of thousands of ton, this type of a large amount of wastes, because of cannot efficient pulverizing and effective environmental protection treatment or utilization can not be carried out, cause huge environmental pollution and the wasting of resources.

Publication number be CN101695710A Chinese patent literature disclosed in technology be after the bulk by discarded glass steel being cut into 1.5cm 10cm, it is placed in organic solvent more swelling, de-except, after organic solvent, pulverizing with conventional disintegrating process in pulverizer, obtain 10 200 object glass comminuted steel shot bodies. Although the method reduces glass reinforced plastic and pulverizes the requirement of equipment, but in implementation process complex process, not only cost is too high, and there is certain potential safety hazard.
