Kupfeka kwekunze kwe3LPE DIN 30670 Mukati meFBE Kupfeka
Tsananguro yeChigadzirwa
Cangzhou Spiral Steel Pipes Group Co., Ltd ine mitsetse mina yekugadzira yekudzivirira ngura nekupisa kupisa kuti iite 3LPE coating uye FBE coating. Dhayamita yepamusoro yekunze inogona kuva 2600mm.
Mapendi acho akakodzera kuchengetedzwa kwemapombi esimbi akavigwa kana kuti akanyudzwa mumvura patembiricha yakagadzirwa kubva -40℃ kusvika +80℃.
Mutemo uripo unotsanangura zvinodiwa zvekuputira zvinoshandiswa pamapombi esimbi akasungirirwa nesimbi uye zvigadziko zvinoshandiswa pakuvaka mapaipi ekutakura mvura kana magasi.
Kushandisa chiyero ichi kunoita kuti PE coating ipe dziviriro yakakwana kubva kumafuta emuchina nemakemikari anoitika panguva yekushanda, kutakurwa, kuchengetwa uye kuiswa.
Machira ekuwedzera ane zvikamu zvitatu: epoxy resin primer, PE adhesive uye extruded polyethylene outer layer. Epoxy resin primer inoshandiswa sehupfu. Adhesive inogona kushandiswa sehupfu kana ne extrusion. Kune machira ekuwedzera, musiyano unoitwa pakati pe sleeve extrusion ne sheet extrusion. Machira e polyethylene akasanganiswa isystem imwe chete kana kuti dzakawanda-layer. Upfu hwe polyethylene hunosanganiswa ne pre-heated component kusvika pahukobvu hwe coating hwaunoda hwasvika.
Epoxy resin primer
Iyo epoxy resin primer inofanira kuiswa muchimiro cheupfu. Ukobvu hwechikamu chidiki i60μm.
PE namira
Namatira yePE inogona kuiswa muchimiro cheupfu kana yakaburitswa. Ukobvu hwechikamu chidiki i140μm. Zvinodiwa pakusimba kwemabvi zvinosiyana zvichienderana nekuti manamira yakashandiswa seupfu here kana kuti yakaburitswa.
Kuputira kwePolyethylene
Kuputira kwepolyethylene kunoiswa nekusvina kana nekubvisa chifukidziro chepurasitiki kana jira. Kuputira uku kunofanira kutonhodzwa mushure mekuiswa kudzivirira kukanganisika kusingadiwe panguva yekufambisa. Zvichienderana nehukuru hwepamusoro, kune mwero wepasi wakasiyana weukobvu hwese hwepurasitiki hwakajairika. Kana paine mitoro yakawedzerwa yemakanika, ukobvu hwepasi hunofanira kuwedzerwa ne0.7mm. Ukobvu hwepasi hunoratidzwa mutafura 3 pazasi.
