Iphakethe elilodwa eliqukethe i-zinc engu-96% kufilimu eyomile, okunye ukusebenza kwe-anti corrosion kuya ediphini elishisayo
Incazelo
I-ZINDN iyiphekhi elilodwa elifaka uthayela eliqukethe uthuli lwezinki elingu-96% kufilimu eyomile futhi linikeza kokubili ukuvikelwa kwe-cathodic kanye nesithiyo sezinsimbi ezisansimbi.
Ingasetshenziswa njengesistimu eyingqayizivele kuphela ukuze ibe enye indlela yokusebenza kwe-anticorrosion ukuze i-hot-dip galvanizing, kodwa njenge-primer ohlelweni lwe-duplex noma uhlelo lwe-ZINDN lwezingqimba ezintathu.
Ingasetshenziswa ngokufafaza, ukuxubha noma ukugingqika ku-substrate yensimbi ehlanzekile nemahhadlahhadla ezinhlobonhlobo zezimo zomoya.
Ukuvikelwa kwe-Cathodic
Ngokugqwala kwe-electrochemical, i-zinc yensimbi nensimbi kuthintana, futhi i-zinc enamandla aphansi e-electrode isetshenziswa njenge-anode, eqhubeka ilahlekelwa ama-electron futhi igqwalile, okungukuthi, i-anode yomhlatshelo;kuyilapho insimbi ngokwayo isetshenziswa njenge-cathode, edlulisela ama-electron kuphela futhi ingashintshi ngokwayo, ngakho ivikelwe.
Okuqukethwe zinc ku-ZINDN galvanizing layer ingaphezu kwama-95%, kanti ubumsulwa bothuli lwezinc olusetshenziswayo buphezulu obungama-99.995%.Ngisho noma ungqimba lwe-galvanizing lonakaliswe kancane, insimbi engaphansi kwesendlalelo se-zinc ngeke igqwale kuze kube yilapho i-zinc idliwe ngokuphelele, futhi okwamanje, ingavimbela ngokuphumelelayo ukusabalala kokugqwala.
Ukuvikelwa kwesithiyo
Indlela ekhethekile yokusabela yenza i-ZINDN galvanizing layer ikwazi ukuzivala ngokuqhubekayo ngokuhamba kwesikhathi ngemva kokufaka isicelo, yenze umgoqo ominyene, ihlukanise ngempumelelo izici zokugqwala, futhi ithuthukise kakhulu ikhono lokulwa nokugqwala.
I-ZINDN ihlanganisa izici zezakhiwo ezimbili ezilwa nokugqwala zibe yinto eyodwa, inqamula umkhawulo wesilinganiso se-pigment-base yezingubo ezivamile, futhi ithola ikhono elihle kakhulu lesikhathi eside lokulwa nokugqwala.
Uthuli lwezinc oluyi-95% kungqimba eyomile ye-ZINDN ewuketshezi, ukugqwala kwamanje kuphezulu kakhulu kunokwembozwe okucebile nge-zinc.
Ngokukhula kothuli lwezinc ongqimbeni lwefilimu elomile, ukugqwala kwamanje kuzokwanda kakhulu, futhi ikhono le-electrochemical anti-corrosion nalo lizokhula kakhulu.
Izinzuzo ze-ZINDN
I-anti-corrosion yesikhathi eside
Izakhiwo zokuvikela ezisebenzayo + Ezingenzi lutho, ukuhlolwa kwesifutho sikasawoti kufika emahoreni angu-4500, kufinyelela kalula eminyakeni engu-25+ yokuphila kokubola.
Ukunamathela okuqinile
Ubuchwepheshe obuthuthukisiwe be-ejenti ye-fusion buxazulule ngokugcwele inkinga yokunamathela yothuli oluphezulu lwe-zinc (> 95%) kwifilimu eyomile.Ingxenye engu-4% yenqwaba ye-ejenti yokuhlanganisa ingabopha ngokuqinile izikhathi ezingu-24 isisindo sayo sothuli lwezinc futhi iyenze ihlangane ne-substrate nokunamathela kufika ku-5Mpa-10Mpa.
Ukuhambisana okuhle
I-ZINDN ingasetshenziswa njengesendlalelo esisodwa noma njengesistimu yezingqimba ezimbili noma ezintathu ezine-ZD sealer, i-topcoat, i-zinc yesiliva, njll., ukuze kuhlangatshezwane nezidingo zamakhasimende ze-anticorrosion ehlala isikhathi eside kanye nomhlobiso omuhle ezimweni ezihlukahlukene zemvelo.
Akukho ukuqhekeka noma ukuwa okusetshenziselwa i-weld
I-ZINDN ixazulule ibhodlela lemboni ukuthi ungqimba oluvuthayo luqhekeka kalula futhi luwa ngokushisela, luqinisekisa ikhwalithi yohlelo lokusebenza.
Kulula ukufaka isicelo
Iphakethe elilodwa, lingasetshenziswa ngokufafaza, ukuxubha noma ukugoqa.Ayishoni phansi, ayivimbi isibhamu, ayivimbeli ipompo, isetshenziswe kahle.
Kuqiza kahle
I-Eco-friendly, izindleko eziphansi, kanye nokuthinta kalula uma kuqhathaniswa ne-hot-dip ne-thermal spray galvanizing.
Izikhawu ezinde phakathi kokuthintwa nokunameka kabusha, izindleko eziphansi ze-anticorrosion yomjikelezo wempilo uma kuqhathaniswa nezingubo ezicebile ze-epoxy zinc.

Uhlelo lokusebenza esizeni
Ngaphambi kokufaka isicelo
Ngemuva kwesicelo se-ZINDN
Inqubo yokufaka isicelo ye-ZINDN
Ukususa amafutha kanye nokuhlanza
Amabala kawoyela angaphezulu kufanele ahlanzwe ngesifutho esinengcindezi ephansi noma ibhulashi elithambile ngesicoci esikhethekile, futhi zonke izinsalela kufanele zihlanzwe ngesibhamu samanzi esisha, noma ziphathwe nge-lye, ilangabi, njll., futhi zihlanjululwe ngamanzi ahlanzekile kuze kube yilapho zingathathi hlangothi.Izindawo ezincane zamabala kawoyela zingakhuhlwa ngama-solvents.
Ukwelashwa kwendawo
Sebenzisa i-sandblasting noma amathuluzi kagesi namathuluzi esandla ukuze ususe ukugqwala, ama-protrusions, kanye nezingxenye ezixebukayo endaweni, ikakhulukazi izingxenye ezigqwalile, futhi izingxenye ezimahhadlahhadla zenziwe bushelelezi ngokushisela.
Ingxube
I-ZINDN ingumkhiqizo wengxenye eyodwa.Ngemuva kokuvula umgqomo, udinga ukugubha ngokuphelele ngethuluzi lamandla.
Isilinganiso sokunciphisa 0-5%;ngenxa yokuhluka kwezinga lokushisa kanye nengcindezi yepompo yesifutho, ukungezwa kwangempela kwe-thinner kusekelwe esimweni sangempela.
Isicelo
Ukuxubha nokugingqa: Kunconywa amabhulashi opende angachithi nama-roller cores, futhi usebenzise indlela ye-criss-cross ukuze ugqoke ngokulinganayo ukuze uqinisekise ukungena okuhle, futhi unake ukuvimbela ukuwohloka nokungalingani.
Ukufafaza: futha iphampu enesilinganiso sokuminyanisa esingaba ngu-1:32, futhi ugcine okokusebenza kokufutha kuhlanzekile.
Kunconywa umbhobho wohlobo lwe-Z, gcina ububanzi besifutho bube ngu-25cm, umlomo wombhobho ubheke endaweni yokusebenza engu-90°C, futhi ibanga lesibhamu libe ngu-30cm.
Phakamisa ukufutha ngezingqimba ezingu-2 zokumboza, Ngemva kokuba ubuso bokuqala bomile, fafaza okwesibili, ubuyisele isibhamu izikhathi ezingu-2, futhi usebenzise ubukhulu befilimu obucacisiwe ngokwezidingo.
