環氧粉(fen)(fen)末防(fang)腐螺(luo)旋(xuan)鋼管，母管為螺(luo)旋(xuan)鋼管，進行環氧粉(fen)(fen)末防(fang)腐處理，熔結環氧粉(fen)(fen)末分類：

1）按(an)使(shi)用方法可(ke)分為(wei)：管道內噴(pen)(pen)涂(tu)用粉(fen)(fen)、管道外噴(pen)(pen)涂(tu)用粉(fen)(fen)、管道內外通(tong)用粉(fen)(fen)。管道外噴(pen)(pen)涂(tu)用粉(fen)(fen)又分為(wei)：單層粉(fen)(fen)、雙(shuang)層粉(fen)(fen)、三(san)層結構防腐用粉(fen)(fen)；

2）按用(yong)(yong)途可分為：石(shi)油天然(ran)氣管(guan)(guan)(guan)道(dao)用(yong)(yong)粉(fen)、飲用(yong)(yong)水管(guan)(guan)(guan)道(dao)用(yong)(yong)粉(fen)、消防管(guan)(guan)(guan)道(dao)用(yong)(yong)粉(fen)、煤礦抗靜電(dian)通風管(guan)(guan)(guan)道(dao)用(yong)(yong)粉(fen)、化工管(guan)(guan)(guan)道(dao)用(yong)(yong)粉(fen)、石(shi)油鉆桿用(yong)(yong)粉(fen)、管(guan)(guan)(guan)件用(yong)(yong)粉(fen)、船舶管(guan)(guan)(guan)道(dao)用(yong)(yong)粉(fen)、高鹽(yan)水重(zhong)防腐管(guan)(guan)(guan)道(dao)用(yong)(yong)粉(fen)等。

3）按固(gu)化(hua)(hua)(hua)條(tiao)件可(ke)分為(wei)：快速(su)固(gu)化(hua)(hua)(hua)、普通固(gu)化(hua)(hua)(hua)兩種(zhong)類型。快速(su)固(gu)化(hua)(hua)(hua)粉末的固(gu)化(hua)(hua)(hua)條(tiao)件一(yi)般(ban)為(wei)230℃/0.5~2min，主(zhu)要用于管道外噴涂(tu)(tu)或三層防腐(fu)結構，由(you)于固(gu)化(hua)(hua)(hua)時間短，生(sheng)產效率(lv)高，適合流水線作業；普通固(gu)化(hua)(hua)(hua)粉末的固(gu)化(hua)(hua)(hua)條(tiao)件一(yi)般(ban)為(wei)230℃/5min以上(shang)，由(you)于固(gu)化(hua)(hua)(hua)時間長，涂(tu)(tu)層流平(ping)好(hao)，適用于管道內噴涂(tu)(tu)。

內熔(rong)結環氧(yang)(yang)粉末涂(tu)(tu)層(ceng)是近年來(lai)發展起來(lai)的新型防腐層(ceng)，采用靜電(dian)噴涂(tu)(tu)工藝涂(tu)(tu)敷環氧(yang)(yang)粉末涂(tu)(tu)料，一次成(cheng)膜。該涂(tu)(tu)層(ceng)具(ju)有涂(tu)(tu)敷操作簡單、無污染(ran)、涂(tu)(tu)層(ceng)抗(kang)沖擊和抗(kang)彎曲性能好(hao)、耐溫(wen)性能高等特點。

用途：產(chan)品廣泛應用于輸油管(guan)(guan)道(dao)(dao)(dao)、天(tian)然氣管(guan)(guan)道(dao)(dao)(dao)、供熱管(guan)(guan)道(dao)(dao)(dao)、供水管(guan)(guan)道(dao)(dao)(dao)。
