Spiral simbi mapaipi anonyanya kushandiswa sepombi dzemvura uye pombi dzekuputira. Kana iyo pombi yesimbi ikashandiswa kudhiraivha mvura, inowanzoitwa anti-corrosion kurapwa mukati kana kunze kwepamusoro. Kazhinji anti-corrosion mishonga inosanganisira 3pe anti-corrosion, epoxy coal tar anti-corrosion, uye epoxy powder anti-corrosion. Mirira, nokuti epoxy poda dipping process inotambudzwa nematambudziko ekunamatira, iyo epoxy powder dipping process haina kumbosimudzirwa. Ikozvino, nekubudirira kwekugadzirwa kwe special phosphating solution ye epoxy powder dipping, dambudziko rekunamatira epoxy poda dipping process rakakundwa kekutanga, uye kubuda kwe epoxy poda dipping kwatanga kuoneka.

Tichiongorora zvinokonzeresa kusaenzana kwe-anti-corrosion coating ukobvu pamapombi esimbi espiral, ukobvu husina kuenzana hwe3PE spiral simbi pombi machira anonyanya kuratidzwa muhukobvu husina kuenzana hwemapoinzi ebvunzo padivi rega rega rakagoverwa munzira inotenderera. Iyo indasitiri yakajairwa SY/T0413-2002 haina mitemo yekuenzana kweukobvu. Inotaridza ukobvu hwekufukidzira asi kunoda kuti ukobvu ukoshi hwejasi haugone kudzika pane ukobvu kukosha kwepoindi, pane kuenzana kukosha kweakawanda bvunzo mapoinzi.

Kana ukobvu hwekufukidzira husina kuenzana panguva yekupfekedzwa kwepombi dzesimbi dzespiral, iyo yekupfekedza inozoparara. Izvi zvinodaro nekuti kana ukobvu hwejasi pane iyo thinnest chikamu chasvika pane yakatarwa, ukobvu hwechikamu chakakora huchave hukuru kupfuura iyo Coating yakatarwa ukobvu. Uyezve, kupfekedza kusaenzana kunogona kukonzera kuti ukobvu hwehuputi pachikamu chakaonda kwazvo chepombi yesimbi itadze kuzadzisa zvakatemwa. Zvikonzero zvikuru zvekusaenzana ukobvu panguva yekugadzirwa kwezvinhu zvisina kuenzana kugovera uye kukotama kwepombi yesimbi. Nzira inoshanda yekudzora iyo isina kuenzana coating ye 3PE anti-corrosion pombi ndeyekugadzirisa akati wandei extrusion inofa kuita kuti anti-corrosion coating ukobvu munzvimbo dzinoverengeka ive yunifomu sezvinobvira uye kudzivirira simbi isina kukwana pombi kuti isavharwe online.

Wrinkles pamusoro pekuvhara: Kuwedzera uye mhepo ye polyethylene zvinhu pane pombi yesimbi inoda kushandiswa kwesilicone roller. Kugadziriswa kusina kunaka panguva iyi kunogona kukonzera wrinkles pamusoro pekuvhara. Mukuwedzera, kuputika kwefirimu yakanyunguduka apo polyethylene zvinhu zvinosiya kubuda kunofa panguva ye extrusion process ichaitawo kukanganisa kwehutano hwakafanana nemakwinya. Iyo inoenderana nekudzora nzira dzezvinokonzeresa wrinkles dzinosanganisira kugadzirisa kuoma uye kumanikidza kwerubha roller uye kumanikidza roller. Kubva pamaonero aya, zvakakodzera kuwedzera extrusion uwandu polyethylene kudzora kunyunguduka firimu kuputika.
