废胶粉 meaning in English
ground-up scrap
Examples
- For the sustainable development , utilization of resources and environmental protection , the main reclamation way for waster rubber was to produce waster rubber powder
摘要为了可持续发展、充分利用资源和保护环境，废橡胶的回收利用应以生产废胶粉为主。 - The asphalt modified by waster rubber powder has lower cost and better properties than those by sbs , and had vast range of prospects for the application in the superhighway
用废胶粉改性的沥青，不仅价格低，而且性能优于sbs改性者，用于修建高速或高等级公路，具有良好前景。 - The results show that adding finery ground rubber powder into asphalt is an effective way to improve its properties at low temperature and aging properties , and the used tyres could be used
经过大量的实验证明,利用精细废胶粉改性道路石油沥青是一条较好的途径,既使沥青路面低温性能、抗老化等能力增加,并且又可解决由于废轮胎积存而导致的污染问题。 - And reached the following specific conclusions : rubber content with the increase of resistance to ageing rubber modified asphalt increased ageing after less than for low - temperature service , the quality of reduced losses , soften point increase needle into a normal degree . summed up the aging asphalt and modified asphalt laws made spent rubber for asphalt modified agents , the principles of the size options and dosage of rubber powder for spent rubber modified asphalt road asphalt in the application provided a good technical support
得出了随胶粉含量的增加胶粉改性沥青的抗老化性能提高,老化后低温延度比减小、质量损失量减小、软化点提高,针入度呈正态分布及改性沥青老化的规律,提出了废胶粉用作沥青改性剂时粒径选择和掺量确定的原则,为废胶粉改性沥青在公路沥青路面中的应用提供了良好的技术支持。 - In this paper , the method of rubber regeneration to modify the grt was investigated in order to decrease the crosslink density of ground rubber tyre ( grt ) and try to improving the interfacial contact state between grt and waste polypropylene ( wpp ) , mechanism of proton - transfer devulcanization was studied in the first time
本文研究了两类再生剂de - link和乙撑胺对废胶粉( grt )的改性效果，来适当降低胶粉的交联度并试图改善其与废聚丙烯( wpp )之间的界面接触情况，并首次对质子转移法脱硫的机理进行了探讨。
