Imodi yokuxhuma yepayipi lomlilo: intambo, i-groove, i-flange, njll. Ipayipi yensimbi ehlanganisiwe ye-epoxy yangaphakathi nangaphandle yokuvikela umlilo iyimpushana ye-anti-corrosion epoxy resin eguquliwe, enokumelana okuhle kakhulu kwamakhemikhali. Ngokuyisisekelo ixazulula izinkinga eziningi ezifana nokugqwala kokugqwala kanye nokukalwa kodonga lwangaphakathi kwemikhiqizo efanayo ngemva kokusetshenziswa isikhathi eside, ukuze kugwenywe ukuvinjelwa kwangaphakathi okuthinta ukusetshenziswa, ukuze kuthuthukiswe kakhulu impilo yesevisi yamapayipi akhethekile okulwa nomlilo. Ngenxa yokwengezwa kwezinto ezivimbela ilangabi ezintweni zokugqoka, ukumelana nokushisa komkhiqizo kuyathuthukiswa uma kuqhathaniswa neminye imikhiqizo efanayo. Ngakho-ke, ngeke kuthinte ukusetshenziswa lapho izinga lokushisa le-ambient likhuphuka kakhulu. Ukuphila kwenkonzo nokusebenza kwamapayipi omlilo afakwe ngaphakathi nangaphandle kungcono kakhulu kunamapayipi anamathangi. Umbala ubomvu.

Ifektri yethu igxile ekukhiqizeni ipayipi lomlilo, ipayipi lensimbi elinamandla, ipayipi lokumboza impushana, ipayipi le-powder coating kanye nepayipi lensimbi elingu-6 intshi. Isicelo: ukuhlinzekwa kwamanzi omlilo, ukuhlinzekwa kwegesi kanye nesistimu yamapayipi okuthutha okuphakathi kwegwebu. Ikhwalithi yomkhiqizo idlula amasiko futhi iphumelele izivivinyo eziningi ngaphambi kokushiya imboni. Ukuthobela izindinganiso zekhwalithi zikazwelonke nezamazwe ngamazwe.

(1) Izakhiwo eziphakeme zemishini. I-epoxy resin inokubumbana okuqinile kanye nesakhiwo samangqamuzana aminyene, ngakho izakhiwo zayo zomshini ziphakeme kunezinsalela ezivamile ze-thermosetting njenge-phenolic resin ne-polyester engagcwalisiwe.

(2) Ukufakwa kwepayipi lomlilo eliboshwe ngepulasitiki lisebenzisa i-epoxy resin, enamathela ngokuqinile. Uhlelo lokwelapha lwe-epoxy resin luqukethe iqembu le-epoxy, iqembu le-hydroxyl, isibopho se-ether, isibopho se-amine, isibopho se-ester namanye amaqembu asezindaweni ezishisayo anomsebenzi omkhulu, okunikeza imikhiqizo ephulukisiwe ye-epoxy ukunamathela okuhle kwensimbi, i-ceramics, ingilazi, ukhonkolo, ukhuni namanye ama-polar substrates.

(3) Ukuncipha okuncane kokwelapha. Ngokuvamile 1% ~ 2%. Ingolunye lwezinhlobo ezinokuncipha okuncane kokupholisa phakathi kwama-thermosetting resin (i-phenolic resin ingu-8% ~ 10%; inhlaka ye-polyester engagcwele ingu-4% ~ 6%; i-silicone resin ingu-4% ~ 8%). I-coefficient yomugqa yokwandisa nayo incane kakhulu, ngokuvamile i-6 × 10-5/℃。 Ngakho-ke, ivolumu iyashintsha kancane ngemva kokuphulukiswa.

(4) Umsebenzi omuhle. I-epoxy resin empeleni ayikhiqizi ama-volatiles aphansi ngesikhathi sokwelashwa, ngakho-ke ingakhiwa ngaphansi kwengcindezi ephansi noma ingcindezi yokuxhumana. Ingakwazi ukusebenzisana nama-ejenti ahlukahlukene okwelapha ukuze kukhiqizwe izinto zokumboza ezivumelana nemvelo ezifana ne-solvent-free, i-high solid, i-powder coatings kanye nezingubo ezisekelwe emanzini.

(5) Ukufakwa kukagesi okuhle kakhulu. I-Epoxy resin iyi-resin ye-thermosetting enezici ezinhle ze-antistatic.

(6) Ukuzinza okuhle nokumelana namakhemikhali okuhle kakhulu. I-epoxy resin ngaphandle kwe-alkali, usawoti kanye nokunye ukungcola akulula ukuwohloka. Uma nje igcinwe kahle (ivaliwe, ingenawo umswakama kanye nokushisa okuphezulu), isikhathi sokugcina unyaka ongu-1. Ngemuva kosuku lokuphelelwa yisikhathi, uma ukuhlolwa kufanelekile, kusengasetshenziswa. I-epoxy curing compound inokuqina okuhle kwamakhemikhali. Ukumelana nokugqwala kwayo ku-alkali, i-asidi, usawoti kanye neminye imithombo yezindaba ingcono kune-resin ye-polyester engagcwalisiwe, i-phenolic resin nezinye izinhlaka ze-thermosetting. Ngakho-ke, i-epoxy resin isetshenziswa kabanzi njenge-anti-corrosion primer. Ngenxa yokuthi i-epoxy resin ephulukisiwe inesakhiwo senethiwekhi enezinhlangothi ezintathu futhi ingamelana nokungeniswa kukawoyela, isetshenziswa kakhulu odongeni lwangaphakathi lwamathangi kawoyela, amathangi kawoyela nezindiza.

(7) Ukumelana nokushisa kwenhlanganisela ye-epoxy yokwelapha ngokuvamile kuba ngu-80 ~ 100 ℃. Izinhlobo ezikwazi ukumelana nokushisa ze-epoxy resin zingafinyelela ku-200 ℃ noma ngaphezulu.
