Ngaphandle kwepayipi lepulasitiki elihlanganisiwe le-PE
Ngaphandle kwepayipi lepulasitiki elihlanganisiwe le-PE, ipayipi lensimbi elihlanganisiwe (eligoqiwe) elihlanganisiwe ngaphandle kwemikhawulo yobubanzi, ubukhulu bongqimba lwe-lining bungabuye bukhethwe ngokungenasisekelo, ngokuya ngezimo zokugqwala okuphakathi, khetha ukushuba okuhlukile kolwelwesi, ubude bungafinyelela ku-6-12 amamitha;Ububanzi obufanayo obufanayo, ipayipi lensimbi elihlanganisiwe (eligoqiwe) elihlanganisiwe ngokuvamile liphakathi kuka-0.5-1mm, indawo ye-tube ebushelelezi, hhayi kuphela i-coefficient yokungqubuzana encane, futhi i-coefficient yokungqubuzana nayo incane, ukulahlekelwa koketshezi ku-tube kuncane, ukugeleza kokudlulisela kukhulu, ukuze kuzuzwe ukonga amandla.Eminyakeni yamuva, i-anti-corrosion spiral amapayipi ensimbi asetshenziswa kabanzi ekwakheni amanzi kanye ne-drainage, amapayipi okusabalalisa amanzi okuphuza ubunjiniyela, ukulawula umlilo, ipayipi lensimbi yomlilo kakhulu ngaphambi kokusebenzisa ipayipi lensimbi elishisayo, umphakathi omningi, amahhotela, izakhiwo zamahhovisi manje zisebenzisa i-epoxy powder anticorrosive steel pipe enezinhlangothi zombili ipulasitiki eboshwe isetshenziswa kokubili ngaphakathi nangaphandle njengempahla yamapayipi omlilo, ukubukeka kwayo kukuhle futhi kuhlala isikhathi eside, Isibe umkhiqizo omkhulu wezimboni ezisafufusa ekhulwini lama-21.I-PE ngaphakathi kwe-EP ehlanganiswe ne-plastic steel tube yokuthengisa yochwepheshe ye-powder camera steel tube yengeze i-flame retardant kanye ne-epoxy resin powder eguquliwe, ukumelana kwezinga lokushisa kwe-coating kuphakeme, ekusetshenzisweni kwesikhathi eside akushi, akuthambisi.
Ngaphandle Pe Composite Coated Plastic Pipe, Izinzuzo
Ifilimu kapende ye-epoxy powder anticorrosive steel tube iqinile, imelana namanzi futhi ayinabo ubuthi.Ukunamathela okuqinile, ukunamathela okuhle phakathi kwefilimu kapende nefilimu yokupenda.Ukumelana nokugqwala okuhle kakhulu nokumelana namanzi, ukusetshenziswa kwezinto ezingavuthiwe ezinhle kakhulu zokulwa nokugqwala, ukuze kuqinisekiswe ukusebenza kwayo kokugqwala.Inamandla amahle emishini, ifilimu eqinile, ukumelana nokuhuzuka kanye nokumelana nomthelela.Okuqukethwe okuphezulu okuqinile, ifilimu ewugqinsi.Isakhiwo se-molecular of epoxy powder anticorrosive steel pipe sibonakala ngamaqembu e-epoxy asebenzayo eketangeni lamangqamuzana, angatholakala ekugcineni, phakathi noma isakhiwo sendandatho yeketango lamangqamuzana.
Ngenxa yamaqembu e-epoxy asebenzayo esakhiweni samangqamuzana, angaphambana nezinhlobo ezahlukene ze-ejenti elaphayo ukuze akhe ama-polymer angancibilikiyo futhi angenakunyakaziswa anesakhiwo senethiwekhi yezindlela ezintathu.I-Thermosetting powder coatings isetshenziswa kakhulu emazweni ahlukahlukene: i-epoxy powder coatings, i-epoxy phenolic powder coatings, i-polyester powder coatings, i-epoxy-polyester powder coatings.Phakathi kwazo, i-epoxy powder coating iyinhlobonhlobo yokuqala yokusetshenziswa, futhi ingukukhiqizwa kwamanje kwe-plastic powder coating, esetshenziswa kabanzi kwinqubo yokufafaza i-electrostatic, ekuhlanganiseni kokuhlobisa kudlala isikhundla esibaluleke kakhulu;Ngenxa yokumelana kwayo nokugqwala kwamakhemikhali aphezulu, i-epoxy phenolic powder coating isetshenziswa kakhulu ekulweni nokugqwala.
I-Thermoplastic Powder Coatings Ikakhulukazi
I-Polyethylene powder coating, i-POLYvinyl chloride powder coating, i-polypropylene powder coating, i-chlorinated polyether powder coating, i-nylon powder coating, i-polyphenylene sulfide powder coating, njll., lezi zimbozo ze-thermoplastic powder zinezinzuzo kanye nobubi.Amapulastiki e-thermosetting anokwelawa okungcono kanye nokuba manzi ngenxa yesisindo sawo samangqamuzana amancane, okuwenza anamathele ngokuqinile emzimbeni weshubhu lapho emboza amashubhu ensimbi, futhi angenza ishubhu lensimbi elimboziwe lithole indawo yefilimu yepulasitiki ebushelelezi.Amapulasitiki asetshenziswa kakhulu e-thermosetting yilezi: i-epoxy resin, i-phenolic resin, i-amino resin nokunye.Ugqinsi lodonga lokumboza luphakathi kwama-microns angu-100 nama-microns angu-500, ngokuvamile ama-microns angu-350.
Ngaphandle kwepayipi lepulasitiki elihlanganisiwe le-PE elihlanganisiwe, 1. Impilo, ayinabo ubuthi, akukho ukukala, akukho ukuzalanisa kwamagciwane, kuqinisekisa ikhwalithi yoketshezi 2. 3. Inqubo yokufaka ivuthiwe, ilula futhi iyashesha, futhi ukuxhumana nepayipi elivamile lama-galvanized okufanayo.4. Ukumelana nesimo sezulu esihle.5. Udonga lwamapayipi abushelelezi, thuthukisa ukusebenza kahle kokudlulisa, impilo ende yenkonzo.
Ngaphandle kwepayipi lepulasitiki elihlanganisiwe le-PE, Imodi yokuxhuma:uxhumano lwentambo: sebenzisa i-manual die twisted wire noma umshini wemikhono yentambo kagesi ukucubungula intambo yepayipi, qaphela ukupholisa ngesikhathi sokucubungula;Ukuxhumeka kwe-Flange, ukukalwa kwendawo, ukudweba ipayipi lomugqa owodwa wokucubungula imephu, ukucubungula ukunamathela, umugqa wepulasitiki, bese uthuthelwa ekufakweni kwendawo;Ipayipi lensimbi yepulasitiki engamboziwe, enomugqa nokufakwa kwamapayipi kungasetshenziswa ensimini, ukushisela i-flange, ukuhlanganisa ipayipi, bese kuhlakazwa ukuze kuhlanganiswe, ukucutshungulwa kwepulasitiki, bese kuthuthelwa ekufakweni kwendawo;Ukufakwa kwamapayipi epulasitiki ane-grooved agqitshiwe kufanele kukhethwe;Ama-grooves azocindezelwa umshini wokugoqa ama-groove, futhi ama-grooves kufanele ahambisane nezindinganiso ezifanele.
