常温涂塑钢管制造工艺研究 摘要：目前市场上对大口径涂塑有较大的需求，而以现有的技术条件其制造 成本极高。通过开发专用涂料，实现了常温制造涂塑（弹性体）钢管。其工艺主要 特点：降低了钢管表面处理要求、无需对钢管进行加热处理、无需大型机具。口径 在?10-3800钢管均可实现内外涂塑，产品超过国标要求。该技术填补了大口径涂 塑钢管的空白。涂层全部采用无毒弹性涂料，具有水阻低、带锈防锈和无毒保洁功 效，能有效抑制青苔和红虫的滋生。 关键词：涂塑钢管制造工艺常温大口径 Manufacturingtechniquesoftheplastic-coatedsteeltube undertheroomtemperature Abstract:Thebigcaliberplastic-coatedsteeltubehasagreat needinthemarketrecently,howeverthecostisveryhighwiththe existingtechnology.Thedevelopmentofthespecialpaintmakesthe manufactureoftheplastic-coatedsteeltubebepossibleundertheroom temperature.Thistechniquerequireslesstreatmentonthesurfaceof thetubeandneedlessnessofheattreatmenttothetube,inaddition, thereisnoneedoflargemachines.TubeswithcaliberaboveΦ10-3800 canbepaintedbothinsideandoutside,productsreachthenational standard.Thistechniquesmeetsthedemandoftheofthesteeltubeof bigcaliberpaintmold.Thecoatcontainsnontoxicandelasticpaint whichisoflowwaterresistanceandwhichschlepsrustandguard againstrustandwhichisofthevirtueofkeepingcleanand unpoisonous,alsoitcandepressthegrowthofthelichenandworm effectively.
