鍍鋅方管的優點及性能
1鍍(du)鋅方管(guan)(guan)是近年來外逐漸(jian)在(zai)石(shi)油化(hua)工、供排水等領域推廣使(shi)用的一種新(xin)型(xing)柔性(xing)非金屬(shu)復合材料壓力管(guan)(guan)道(dao),其實質是以(yi)玻璃纖維為增(zeng)強材料,以(yi)不飽和熱(re)固性(xing)聚酯(zhi)樹(shu)脂為基體,中間(jian)夾石(shi)英(ying)砂的壓力管(guan)(guan)(英(ying)文(wen)縮寫名FRP,代(dai)號FWRPMP,簡(jian)稱夾砂管(guan)(guan))。FRP管(guan)(guan)道(dao)目前執行建材行業標(biao)準《玻璃纖維纏(chan)繞增(zeng)強熱(re)固性(xing)樹(shu)脂夾砂壓力管(guan)(guan)》。2
