历史上用于交联氯化聚合物的几种化学品,由于汽车原车制造商的原因,而今要么被限制使用要么很快将被禁止使用。在现有文献介绍推荐的氯化聚合物硫化方法中,含铅化合物和以硫脲为基的硫化体系一直处于支配地位。近来,汽车原车制造商(OEM)指令中已限制使用铅基硫化物,有几种将很
Several chemicals historically used to cross-link chlorinated polymers are now either restricted or banned for use due to the original car manufacturer’s car. Lead compounds and thiourea-based vulcanization systems have been dominating in the literature for recommending chlorinated polymer vulcanization processes. Recently, the use of lead-based sulfides has been restricted in OEM orders,
