挤拉是一种连续性的加工工艺，用合成树脂和增强纤维制成挤拉型材。挤拉复合型材除了有很强的力学
性质，还有以下特殊功能：１．抗腐蚀；２．绝缘； ３．绝热；４．传热性低；
５．稳定性好．广泛用于石油化工，电力工程，交通运输，建筑等众多领域。
It is craft of processing of a kind of consecution that pulls,and use to synthesize the
resin with strengthen the fiber to make into to pull the type.the pull to reunite the type
to besides have very strong mechanics kind,still have below special
function:1..anti;2.insulate;3.the is hot;4.transmit heat the low;5.the stability is good
extensive used for the numerous realm,such as,conveyance,and building etc.of petroleum
chemical engineering,electric power engineering ,transportation. |
