Umbhobho weplastiki odityanisiweyo we-PE wangaphandle
Umbhobho weplastiki odityanisiweyo wangaphandle, umbhobho weplastiki odityanisiweyo (oqengqiwe) wentsimbi ngaphandle kwemida yobubanzi, ubukhulu bomaleko we-lining bunokukhethwa ngokungenamkhethe, ngokweemeko ze-corrosion medium, khetha ubukhulu bomgca ohlukeneyo, ubude bunokufikelela kwi-6-12. iimitha;Ubukhulu obufanayo obuqhelekileyo, i-coefficient yeplastiki edibeneyo yentsimbi edibeneyo iphakathi kwe-0.5-1mm, i-tube surface egudileyo, kungekhona nje i-coefficient ye-friction encinci, kwaye i-coefficient ye-friction nayo incinci, ilahleko yolwelo kwi-tube incinci. ukuhamba kothumelo kukhulu, ukufezekisa ukonga amandla.Kwiminyaka yakutshanje, i-anti-corrosion spiral mibhobho yentsimbi isetyenziswa ngokubanzi ekwakheni unikezelo lwamanzi kunye ne-drainage, imibhobho yokuhambisa amanzi okusela ubunjineli, ulawulo lomlilo, eyona mibhobho yentsimbi yomlilo phambi kokusetyenziswa kombhobho wentsimbi oshushu, uluntu oluninzi, iihotele, Izakhiwo zeofisi ngoku zisebenzisa i-epoxy powder anticorrosive steel pipe enamacala omabini eplastiki egqutywe ifakwe ngaphakathi nangaphandle njengesixhobo sombhobho womlilo, ukubonakala kwayo kukuhle kwaye kuhlala ixesha elide, iye yaba yimveliso enkulu yamashishini asakhasayo ngenkulungwane yama-21.I-PE ngaphakathi kwe-EP egqunywe ngetyhubhu yentsimbi yeplastiki yokuthengisa ityhubhu yentsimbi yomgubo eyongezwe i-flame retardant kunye ne-epoxy resin powder eguquliweyo, ukuxhathisa kobushushu bokwambathisa kuphezulu, ekusebenziseni ixesha elide akutshisi, musa ukuthambisa.
Ngaphandle Pe Composite Coated Umbhobho wePlastiki, izinto eziluncedo
Ifilimu yepeyinti ye-epoxy powder anticorrosive steel tube iqinile, ayinamanzi kwaye ayinayo ityhefu.Ukubambelela okuqinileyo, ukunamathela kakuhle phakathi kwefilimu yepeyinti kunye nefilimu yepeyinti.Ukuchasana nokugqwesa komhlwa kunye nokuxhathisa amanzi, ukusetyenziswa kwezinto ezibalaseleyo zokulwa nomhlwa, ukuqinisekisa ukusebenza kwayo okuchasene nomhlwa.Inamandla omatshini alungileyo, ifilimu enzima, ukuxhathisa kwe-abrasion kunye nokuchasana kwempembelelo.Umxholo oqinileyo ophakamileyo, ifilimu eshinyeneyo.Isakhiwo se-molecular ye-epoxy powder i-anticorrosive steel pipe ibonakaliswe ngamaqela e-epoxy asebenzayo kwi-chain chain, enokuthi ibekwe ekupheleni, phakathi okanye isakhiwo sendandatho ye-molecular chain.
Ngenxa yamaqela e-epoxy asebenzayo kwisakhiwo se-molecular, angakwazi ukunqumla kunye neentlobo ezahlukeneyo ze-agent ephilisayo ukwenza iipolymers ezingenakunyibilika kunye ne-infusible eneendlela ezintathu zenethiwekhi.I-Thermosetting powder coatings isetyenziswa kakhulu kumazwe ahlukeneyo: i-epoxy powder coatings, i-epoxy phenolic powder coatings, i-polyester powder coatings, i-epoxy-polyester powder coatings.Phakathi kwazo, i-epoxy powder yokugqoka i-epoxy powder yintlobo yokuqala yokusetyenziswa, ikwayimveliso yangoku yeplastiki yomgubo, esetyenziswa ngokubanzi kwinkqubo yokutshiza i-electrostatic, kwi-decorative coating idlala indawo ebaluleke kakhulu;Ngenxa yokumelana kwayo nemichiza ephezulu, i-epoxy phenolic powder coating isetyenziswa kakhulu kwi-anti-corrosion coating.
Iingubo zePowder ze-Thermoplastic ziPhakamileyo
I-Polyethylene powder yokugquma, i-POLYvinyl chloride yomgubo, i-polypropylene powder i-polypropylene, i-chlorinated polyether powder coating, i-nayiloni yomgubo we-nylon, i-polyphenylene sulfide powder i-polyphenylene, njl., ezi zigubungele ze-thermoplastic zineenzuzo kunye nezingeloncedo.Iiplastiki ze-Thermosetting zinezinga elingcono lokunyanga kunye nokumanzi ngenxa yobunzima bemolekyuli encinci, ebenza ukuba babambelele ngokuqinileyo kumzimba wetyhubhu xa kugqunywa ityhubhu yentsimbi, kwaye inokwenza ityhubhu yentsimbi egqunywe ngentsimbi ifumane umphezulu wefilimu yeplastiki egudileyo.Iiplastiki ze-thermosetting eziqhelekileyo ezisetyenziswayo zezi: i-epoxy resin, i-phenolic resin, i-amino resin njalo njalo.Ubukhulu bodonga lokugquma buphakathi kwe-100 microns kunye ne-500 microns, ngokuqhelekileyo i-350 microns.
Ngaphandle kwe-PE ehlanganisiweyo yombhobho weplastiki edibeneyo, 1. Impilo, i-non-toxic, akukho scaling, akukho kuzaliswa kwe-microorganisms, ukuqinisekisa umgangatho wolwelo 2. 3. Inkqubo yofakelo ikhulile, ilungele kwaye iyakhawuleza, kunye nokudibanisa nombhobho oqhelekileyo we-galvanized enjalo.4. Ukumelana nemozulu elungileyo.5. Udonga lombhobho ogudileyo, phucula ukusebenza kakuhle kokuhanjiswa, ubomi benkonzo ende.
Umbhobho weplastiki odityanisiweyo wangaphandle we-PE, imowudi yoQhagamshelwano:uxhulumaniso lwentambo: sebenzisa i-manual die die twisted wire okanye umatshini we-sleeve yocingo lombane ukucubungula intambo yombhobho, ingqalelo yokupholisa ngexesha lokucubungula;Uqhagamshelo lweFlange, umlinganiselo wendawo, umzobo wombhobho wokuzoba imephu yokulungisa umgca omnye, ukugquma, ukufakwa kweplastiki, emva koko kuthuthelwe kwindawo yofakelo;Umbhobho wentsimbi yeplastiki engagqunywanga, enomgca weplastiki kunye nokufakelwa kwemibhobho ingasetyenziswa ebaleni, ukuwelda i-flange, ukudibanisa umbhobho, kwaye emva koko udityaniswe ukugquma, ukusetyenzwa kweplastiki enemigca, emva koko ithuthelwe kwindawo yofakelo;Iifakelo zemibhobho yeplastiki egqityiweyo egqitywe ngegrooved kufuneka ikhethwe;Iigrooves ziya kucinezelwa ngumatshini ojikelezayo we-groove, kwaye i-grooves iya kuhambelana nemigangatho efanelekileyo.
