for other substances, such as rubber, for which vulcanization makes the reprocessing of tyre rubber into new tyres almost impossible, alternatives need to be found.
其他一些物质,例如橡胶,则需要寻找其他的办法,因为几乎不可能用硫化方法把轮胎橡胶变成新的轮胎。
a report published by calrecovery inc. in 2004 lists approximately 50 organic compounds, including benzene, toluene and heptanes as types of emissions from the vulcanization area of a tyre retreading operation and from a tyre retreading extrusion operation.
2004年公布的报告列出了从轮胎翻新作业的硫化区域和轮胎翻新挤压作业中产生的约50种有机化合物的排放,包括苯、甲苯和庚烷。
it is used as an alloying agent in iron and steel (the dominant use, up to 0.1%), in thermoelectric alloys, in fuse wire for explosives, in catalysts, in vulcanization and as a colorant in glasses and ceramics.
它可作为一种合金添加剂用于铁和钢(主要用途,达0.1%)、热电偶合金、爆破器材用的保险丝、催化剂、硫化加工以及作为玻璃和水泥的着色剂。
