Pombi Isina Chinhu :
Pombi inoonekwa seisina chinhu kana isina chifukidziro chakanamirwa pairi. Kazhinji, kana yangopetwa pamigayo yesimbi, chinhu chisina chinhu chinotumirwa kunzvimbo yakagadzirirwa kuchengetedza kana kuputira chinhu chacho nechinhu chaunoda (izvo zvinotsanangurwa nemamiriro evhu enzvimbo iri kushandiswa chinhu chacho). Pombi isina chinhu ndiyo mhando yepombi inonyanya kushandiswa muindasitiri yekuunganidza makomba uye inowanzoiswa muvhu kuti ishandiswe muchimiro. Kunyangwe pasina zvidzidzo zvechokwadi zvinoratidza kuti pombi isina chinhu yakasimba pane pombi yakafukidzwa pakushandisa makomba, pombi isina chinhu ndiyo yakajairika muindasitiri yekuvaka.
Pipe yekusimbisa :
Kuisa simbi mumagetsi kana kuti galvanization ndeimwe yemhando dzinonyanya kufarirwa dzekuisa simbi mupombi. Kunyangwe simbi pachayo iine hunhu hwakanaka kana zvasvika pakudzivirira ngura uye simba rekusunga, inoda kuputirwa ne zinc kuti ipedzise zviri nani. Kuisa simbi mumagetsi kunogona kuitwa nenzira dzakasiyana-siyana, zvichienderana nekuwanikwa kwenzira yacho. Zvisinei, nzira inonyanya kufarirwa ndeyekuisa simbi mumoto kana kuti batch dip galvanization iyo inosanganisira kunyudza pombi yesimbi mubhavhu re zinc yakanyungudutswa. Kuita kwesimbi kunoumbwa nesimbi yesimbi ne zinc kunoita kuti simbi ipedzise pamusoro pesimbi iyo inopa hunhu hunodzivirira ngura husati hwambovapo papombi. Imwe mukana wekuisa simbi mumagetsi ndewekuti mutengo wayo unobatsirika. Sezvo maitiro acho ari nyore uye asingade mashandiro akawanda echipiri uye mushure mekugadzirisa, yave iri sarudzo yakanaka kune vagadziri vazhinji nemaindasitiri.
FBE - Pombi Yekuputira Poda Yakasungirirwa neFusion Bonded Epoxy :
Kuputira pombi uku kunopa dziviriro yakanaka kwazvo kumapaipi madiki kusvika makuru ane dhayamita iri pakati nepakati ane tembiricha iri pakati nepakati (-30C kusvika 100C). Kushandiswa kwayo kunowanzo shandiswa pamapaipi emafuta, gasi, kana emvura. Kunamatira kwakanaka kunobvumira kuramba ngura kwenguva refu uye kudzivirira pombi. FBE inogona kushandiswa sechikamu chine mbiri chinopa hunhu hwakasimba hwemuviri hunoderedza kukuvara panguva yekubata, kutakurwa, kuiswa, uye kushanda.
Pombi Inodzivirira Kuora Kwesimbi Yechikamu Chimwechete: Kuvhara kwesimba remagetsi;
Pombi yeDouble Layer Fusion Bonded Epoxy Anticorrosive: Pombi ye epoxy ine fistly pasi, uye Pombi ye epoxy pamusoro.
3PE Epoxy Coating Pipe :
Pombi yesimbi yakaputirwa neEpoxy ine machira matatu, yekutanga FBE coating, yepakati ine adhesive layer, yekunze polyethylene layer. Pombi yekuputira ye3PE chimwe chigadzirwa chitsva chakagadzirwa kubva kuma1980, chine adhesives uye PE(polyethylene). 3PE inogona kusimbisa hunhu hwemakanika epaipi, inodzivirira magetsi zvakanyanya, haipindi mvura, inopfekwa, uye inodzivirira kukwegura.
Zvekutanga zvikamu zve epoxy yakasungirirwa pamwe chete, ukobvu hwayo hwakakura kupfuura 100μm. (FBE ＞100μm）
Chikamu chechipiri chinonamira, izvo zvinobatanidza epoxy nePE layers. (AD: 170~250μm)
Matinji echitatu iPE layers inova polyethylene ane zvakanakira kudzivirira mvura, kudzivirira magetsi uye kudzivirira kukuvara kwemuchina. (φ300-φ1020mm)
Saka, mapaipi ekuputira e3PE akabatana nemabhenefiti eFBE nePE. Anoshandiswa zvakanyanya mukutakura mvura, gasi nemafuta pamapaipi akavigwa.
