Ipakethi enye equlethe i-96% ye-zinc kwifilimu eyomileyo, enye indlela yokusebenza kwe-anti corrosion ukuya kwidiphu eshushu.
Inkcazo
I-ZINDN yipakethe enye yokugquma i-galvanizing equkethe i-96% yothuli lwezinc kwifilimu eyomileyo kwaye inikezela zombini ukhuseleko lwe-cathodic kunye nezithintelo zesinyithi.
Ingasetyenziswa njengenkqubo eyodwa kuphela ukuba ibe yinkqubo ye-anti-corrosion kwi-hot-dip galvanizing, kodwa njenge-primer kwinkqubo ye-duplex okanye inkqubo yokwaleka kwe-ZINDN enemigangatho emithathu.
Ingasetyenziswa ngokutshiza, ukuxubha okanye ukuqengqeleka kwi-substrate yentsimbi ecocekileyo nerhabaxa kwiimeko ezininzi zomoya.
Ukukhuselwa kweCathodic
Kwi-corrosion ye-electrochemical corrosion, i-zinc yensimbi kunye nentsimbi zidibene kunye, kwaye i-zinc ene-electrode engaphantsi kwamandla isetyenziswe njenge-anode, eqhubeka ilahlekelwa yi-electron kwaye i-corrod, oko kukuthi, i-anode yombingelelo;ngelixa intsimbi ngokwayo isetyenziselwa i-cathode, ehambisa kuphela i-electron kwaye ayitshintshi ngokwayo, ngoko ikhuselwe.
Umxholo we-zinc kwi-ZINDN ye-galvanizing layer ingaphezulu kwe-95%, kwaye ukucoceka kothuli lwe-zinc olusetyenzisiweyo luphezulu njenge-99.995%.Nangona i-galvanizing layer yonakaliswe kancinane, intsimbi ephantsi kwe-zinc layer ayiyi kugqwala de kube i-zinc idliwe ngokupheleleyo, kwaye okwangoku, inokuthintela ngokufanelekileyo ukusasazeka kwe-rust.
Ukukhuselwa komqobo
Indlela yokusabela ekhethekileyo yenza ukuba i-ZINDN ikwazi ukutywinwa ngakumbi ngokuhamba kwexesha emva kokufakwa kwesicelo, ukwenza umqobo oshinyeneyo, ukwahlula ngokufanelekileyo imiba ye-corrosion, kunye nokuphucula kakhulu isakhono sokuchasa umhlwa.
I-ZINDN idibanisa iimpawu zeempawu ezimbini ezichasene ne-corrosion zibe yinto enye, iqhekeza umda we-pigment-base ratio ye-coatings eqhelekileyo, kunye nokufumana ubuchule obugqwesileyo bexesha elide lokuchasa ukubola.
I-95% yothuli lwe-zinc kwifilimu eyomileyo ye-ZINDN ye-galvanizing, ubuninzi be-corrosion yangoku iphezulu kakhulu kune-coating ene-zinc-rich.
Ngokunyuka kothuli lwe-zinc kuluhlu lwefilimu eyomileyo, ubuninzi be-corrosion yangoku buya kunyuka kakhulu, kwaye i-electrochemical anti-corrosion ability nayo iya kwanda kakhulu.
Izinto ezilungileyo zeZINDN
I-anti-corrosion yexesha elide
Iipropathi eziSebenzayo + eziSebenzayo zokukhusela ezimbini, uvavanyo lwesitshizi setyuwa ukuya kuthi ga kwiiyure ezingama-4500, ukufikelela ngokulula ukuya kwiminyaka engama-25+ ubude bobomi bokungagugi.
Ukubambelela okuqinileyo
Itekhnoloji ye-agent ye-fusion ephuhlisiwe yasombulula ngokupheleleyo ingxaki yokubambelela kuthuli oluphezulu lwe-zinc (> 95%) kwifilimu eyomileyo.I-4% iqhezu lobunzima be-agent ye-fusion inokudibanisa ngokuqinileyo amaxesha angama-24 ubunzima bayo be-zinc uthuli kwaye yenza i-bond kunye ne-substrate kunye nokubambelela ukuya kwi-5Mpa-10Mpa.
Ukuhambelana kakuhle
I-ZINDN ingasetyenziselwa njengoluhlu olulodwa okanye njengenkqubo yemigangatho emibini okanye emithathu kunye ne-ZD sealer, i-topcoat, i-zinc yesilivere, njl., ukuhlangabezana neemfuno zabathengi be-anticorrosion ehlala ixesha elide kunye nokuhlobisa okuhle kwiimeko ezahlukeneyo zokusingqongileyo.
Akukho kuqhekeka okanye ukuwa kusetyenziswe kwi-weld
I-ZINDN yasombulula i-bottleneck yoshishino ukuba i-galvanizing layer iqhekeka ngokulula kwaye inikezela ngokuwa kwi-weld, iqinisekisa umgangatho wesicelo.
Kulula ukufaka isicelo
Ipakethe enye, ingasetyenziswa ngokutshiza, ukuxukuxa okanye ukuqengqeleka.Ayifaki phantsi, ayithinteli umpu, ayithinteli ipompo, isetyenziswe ngokufanelekileyo.
Isebenza kakuhle emalini
I-Eco-friendly, ixabiso eliphantsi, kunye nokucofa ngokulula xa kuthelekiswa ne-hot-dip kunye ne-thermal spray galvanizing.
Amathuba amade phakathi kokucofa phezulu kunye nokuphinda kuqatywe, ixabiso eliphantsi le-anticorrosion yomjikelo wobomi xa kuthelekiswa neengubo ezityebileyo ze-epoxy zinc.

Ukususa amafutha kunye nokucoca
Amabala e-oyile angaphezulu kufuneka ahlanjululwe ngokutshiza okuphantsi okanye ibrashi ethambileyo kunye nesicoci esikhethekileyo, kwaye zonke iintsalela kufuneka zihlanjululwe ngompu wamanzi amatsha, okanye ziphathwe nge-lye, ilangatye, njl., kwaye zihlanjululwe ngamanzi amatsha kude kube kungathathi hlangothi.Iindawo ezincinci ze-oyile ziyakwazi ukuxutywa nge-solvents.
Unyango lomphezulu
Sebenzisa izixhobo zesanti okanye izixhobo zombane kunye nezixhobo zesandla ukususa umhlwa, iiprotrusions, kunye neendawo ezixobukayo kumphezulu, ngakumbi iindawo ezinomhlwa, kwaye iindawo ezirhabaxa zigudiswa ngokuwelda.
Umxube
I-ZINDN yimveliso yecandelo elinye.Emva kokuvula umgqomo, kufuneka ugxothwe ngokupheleleyo ngesixhobo samandla.
I-Dilute ratio 0-5%;ngenxa yokwahlukana kweqondo lokushisa kunye noxinzelelo lwempompo yokutshiza, ukongezwa kwangempela kwe-thinner kusekelwe kwimeko yangempela.
Isicelo
Ukuxubha kunye nokuqengqeleka: iibrashi zepeyinti ezingachithiyo kunye ne-roller cores ziyacetyiswa, kwaye usebenzise indlela ye-criss-cross ukuze unxibe ngokulinganayo ukuqinisekisa ukungena okulungileyo, kwaye ubeke ingqalelo ukuthintela ukudodobala kunye nokungalingani.
Ukutshiza: impompo yokutshiza enomlinganiselo omalunga ne-1:32, kwaye ugcine izixhobo zokutshiza zicocekile.
I-nozzle yohlobo lwe-Z iyacetyiswa, gcina ububanzi bokutshiza malunga ne-25cm, umlomo we-nozzle u-perpendicular kwi-workpiece kwi-90 ° C, kunye nomgama wompu malunga ne-30cm.
Phakamisa ukutshiza ngemigangatho ye-2 yokwambathisa, Emva kokuba ubuso bexesha lokuqala bomile, fafaza okwesibini, ubuyisele umpu ngamaxesha angama-2, kwaye usebenzise ubuninzi befilimu obuchaziweyo ngokweemfuno.
