Kunze 3LPE Coating DIN 30670 Mukati FBE Coating
Product Description
Cangzhou Spiral Steel Pipes Group Co., Ltd ine mitsetse mina yekugadzira yeanticorrosion & thermal insulation kuita iyo 3LPE coating uye FBE coating.Iyo yakawanda yekunze dhayamita inogona kuva 2600mm.
Iwo machira akakodzera kuchengetedzwa kwepombi dzesimbi dzakavigwa kana dzakanyura pamatembiricha ekugadzira -40 ℃ kusvika +80 ℃.
Iyo yazvino chiyero inotsanangura zvinodikanwa zvemajasi anoiswa kune spiral welded simbi pombi uye zvigadziriso zvinoshandiswa pakuvaka mapaipi ekufambisa zvinwiwa kana magasi.
Kushandisa chiyero ichi kunovimbisa kuti iyo PE coating inopa dziviriro yakakwana kubva kune mechaniki yekupisa uye kemikari mitoro inoitika panguva yekushanda, kutakura, kuchengetedza uye kuisa.
Machira akawedzeredzwa anosanganisira matatu akaturikidzana: epoxy resin primer, adhesive yePE uye yakawedzera polyethylene yekunze layer.Iyo epoxy resin primer inoshandiswa sehupfu.Iyo yekunamatira inogona kushandiswa sehupfu kana neextrusion.Pamapfekete akawedzera kusiyanisa kunoitwa pakati peiyo sleeve extrusion uye sheet extrusion.Sintered polyethylene coatings ndeye imwechete kana akawanda-layer masisitimu.Iyo polyethylene poda inosanganiswa pane pre-heated component kusvika iyo inodiwa coating ukobvu yasvika.
Epoxy resin primer
Iyo epoxy resin primer inofanirwa kuiswa muhupfu.Ukobvu hwehudiki hunosvika 60μm.
PE adhesive
Iyo PE inonamira inogona kuiswa mune hupfu fomu kana extruded.Ukobvu hwehudiki hunosvika 140μm.iyo peel simba zvinodiwa zvinosiyana zvichienderana nekuti iyo inonamira yaiiswa sehupfu kana yakabviswa.
Polyethylene kupfeka
Iyo polyethylene coating inoshandiswa kungave nekupisa kana ne sleeve kana sheet extrusion.Iyo yekupfekedza inofanirwa kutonhodzwa mushure mekushandisa kudzivirira kusada deformation panguva yekufambisa.Zvichienderana nehukuru hwezita, kune akasiyana madiki makosi eiyo yakajairika yakazara coating ukobvu.Panyaya yekuwedzera ma mechanical mitoro iyo minimu layer gobvu ichawedzerwa ne 0.7mm.ukobvu hwehudiki hunopiwa mutafura 3 pazasi.
