Large-diameter plastic-coated spiral steel pipe ipombi yesimbi ine polymer coating yakapfapfaidza pamusoro pepombi yesimbi. Iyo ine maitiro e-anti-corrosion, kupfeka kuramba, acid uye alkali kuramba, uye anti-kuchembera. Kugadzirwa kwayo kunowanzo sanganisira matanho anotevera:

Simbi pombi kurapa pamusoro pekurapa: Chekutanga, pamusoro pepombi yesimbi inoda kuputika jecha, kupfurwa kuputika, nezvimwewo kubvisa pamusoro pe oxide sikero, mavara emafuta, ngura, uye kumwe kusvibiswa kugadzirira nhanho inotevera yekuvaka kukoira.

Kupfapfaidza kweprimer: Pfaya primer pamusoro pepombi yesimbi, kazhinji uchishandisa epoxy primer kana polyurethane primer. Basa rekutanga nderokudzivirira pamusoro pemapombi esimbi uye kuvandudza kusungirirwa kwekuputira.

Powder coating spraying: Wedzera hupfu hwekuputira kupfuti yekupfapfaidza, uye pfapfaidza iyo yekuputira pamusoro pepombi yesimbi kuburikidza nemaitiro akadai se electrostatic adsorption, kuomesa, uye kusimba. Kune marudzi akawanda ehupfu hwehupfu, hwakadai se epoxy, polyester, polyurethane, pende yekubheka, etc. Unogona kusarudza chipfeko chakakodzera maererano nezvinodiwa zvakasiyana.

Kurapa nekubika: Isa pombi yesimbi yakavharwa muimba yekubikira yekurapa nekubikira, kuitira kuti iyo yekuputira isimbiswe uye inyatsobatanidzwa nepamusoro pepombi yesimbi.

Kuongororwa kwemhando yekutonhora: Mushure mekubheka kwapera, pombi yesimbi inotonhodzwa uye mhando inoongororwa. Kuongorora kwemhando kunosanganisira kuongorora kutaridzika kwekuvhara, kuyerwa kwehukobvu, bvunzo yekunamatira, nezvimwewo kuona kuti chigadzirwa chinosangana nezvinodiwa uye zvinodiwa.

Izvo zviri pamusoro apa ndiyo yakajairika kugadzirwa maitiro kuyerera kwehombe-diameter yepurasitiki-yakavharidzirwa spiral simbi pombi. Vagadziri vakasiyana vanogona kuita imwe gadziriso uye hunyanzvi zvichienderana nemamiriro avo uye nhanho dzehunyanzvi, asi matanho ekutanga ekugadzira akada kufanana.
