辐照交联制备高性能PVC电线电缆料
关键字：PVC
本文采用Co60γ射线辐照交联的方法研究了交联剂TMPTA、改性剂EVA、辐照剂量对PVC电缆料力学性能的影响。通过凝胶含量、断裂伸长率、断裂应力的测定，分析了TMPTA、EVA、辐照剂量对PVC电缆料力学性能的影响。结果表明EVA含量一定时（15wt%）， 电缆料凝胶含量随TMPTA含量的增加、辐照剂量的增大而增大，该体系的力学性能与其凝胶含量存在正比例关系；当TMPTA含量一定时(12wt%)，加入EVA不利于电缆料凝胶含量的提高，材料的力学...

我国PVC产业四大看点
关键字：我国,PVC,产业,四大,
我国PVC产业发展呈现出四大看点：1.2004年产能迅速扩大，产量继续大幅提高，进口量下降，价格稳步上涨。2.国产乙烯供应不足；电石产业发展受到国家政策强制性限制；VCM单体进口来源单一，风险增大；原料供应面临困境。3.2005～2006年产能进入高速增长期，预计到2006年将达到1200万吨/年，2010年将突破1500万吨/年，届时需求量约1000万～1100万吨，将形成供大于需的局面。4.招商热仍在持续，一段时期内仍将是投资热点。 一...

PVC：河北地区PVC市场行情
近期虽然华南地区曾经出现少部分贸易商恐慌抛货导致价格出现回落，但河北地区PVC价格没有受到很大影响，主要是经销商前期操作较谨慎，操作多以现卖现买为主，故整体社会流通库存量较少，经销商不急于降价出货，目前河北地区PVC市场主流价格仍维持在8750-8800元/吨。
当地的PVC生产企业小电石法的多数实际出厂价格在8800元/吨左右，基本和当地的市场价格同步，当地大型的PVC生产企业的出厂价格本周...
