After conjunction, be heated to 150-180 degree, reuse frequency 2250MHz, power 800W microwave carry out processing 10-20 minutes, add stone
Black alkene continues to carry out processing 5-15 minutes with the microwave of frequency 2250MHz, power 800W after mixing, and is transferred to 5-10 DEG C
Sealing and standing 30 minutes in environment, microwave treatment 5 minutes again, then cooled to room temperature is to get modified silicon carbide.
The beneficial effects of the invention are as follows：
1, the plastic grain that the present invention is modified production using waste and old motorcycle shell has preferable intensity, suppleness, resistance to
The qualities such as mill property, oil resistivity, flatness and glossiness, realize the high unity of economic benefit, social benefit and environmental benefit；
2, the present invention will collect the waste and old shell of motorcycle and first carry out scraping paint processing, and be sprayed during scraping paint
Except paint solution, by making the paint on motorcycle shell soften, fall off except the effect of paint solution, to be easier to scrape off, while paint solution is removed
The parts of plastics of shell can also be softened, be made subsequently shorter to the processing time of waste and old shell, it is easier to handle, then except
Adhesion on shell at paint remover and is not fallen off by clean paint block removing using centrifugal treating after the completion of paint, keeps paint removal effect more preferable
It is more complete, then cleaning showers are carried out with cleaning agent, remaining paint remover can be removed, paint remover is avoided to cause subsequent production
When influencing, also can further soften to material, then subsequently carrying out mixing process to material, required time is shorter, place
Reason is easier, and the mixture mixed is put into the resistance to low temperature for carrying out cryogenic freezing processing under low temperature and improving reworked material,
To improve its mechanical property；
