1.Superior Rust Resistance
Chinangwa chikuru chekugadzira ngura ndechekumisa ngura mumakwara ayo-uye ndipo panopinda zinc oxide layer parata. Heino mashandiro azvinoita: zinc coating inotanga kuita ngura, ichitora hit kuitira kuti simbi iri pasi igare yakasimba. Pasina iyi zinc shield, simbi yaizonyanya kuita ngura, uye kunaya, mwando, kana zvimwe zvinhu zvakasikwa zvaizokurumidza kuora.
2.Yakawedzerwa Hupenyu
Uhu hupenyu hurefu hunobva zvakananga kubva pakudzivirira kwekudzivirira. Tsvagiridzo inoratidza kuti, mumamiriro ezvinhu akajairwa, simbi yakabatiswa inoshandiswa mumaindasitiri inogona kugara kwenguva yakareba semakore makumi mashanu. Kunyange munzvimbo dzine ngura zvikuru—funga nzvimbo dzine mvura yakawanda kana kuti mwando—inogona kuramba ichiita makore 20 kana kupfuura.
3.Kuvandudzwa kweAesthetics
Vanhu vazhinji vanobvuma kuti galvanized simbi ine chitarisiko chinokwezva kupfuura mamwe akawanda masimbi alloys. Kumusoro kwayo kunowanzova kujeka uye kuchena, zvichiita kuti itaridzike yakakwenenzverwa.
Iko Kunoshandiswa Simbi Yakagadzirwa
Nzira dzakasiyana dzinogona kushandiswa kugadzira galvanizing:
2. Electro galvanizing
3. Zinc diffusion
4. Metal spraying
Kupisa-kunyura kwakabatiswa
Panguva yekugadzira galvanizing, simbi inonyudzwa mune yakanyungudutswa zinc bath. Kupisa-dip galvanizing (HDG) kunosanganisira matanho matatu akakosha: kugadzirira pamusoro, kuvheneka, uye kuongorora.
Kugadzirira Kwepamusoro
Mukugadzirisa kwepamusoro, simbi yakafanogadzirwa inotumirwa kunovhenekera uye inopinda matanho matatu ekuchenesa: degreasing, acid washing, uye fluxing. Pasina iyi nzira yekuchenesa, galvanizing haigone kuenderera nekuti zinc haiite nesimbi isina kuchena.
Galvanizing
Mushure mekugadzirwa kwepamusoro kwapera, simbi inonyudzwa mu98% yakanyungudutswa zinc pa830°F. Kona iyo simbi inonyudzwa muhari inofanira kubvumira mweya kubuda kubva kune tubular zvimiro kana mamwe mahomwe. Izvi zvinobvumirawo zinc kuyerera nepakati uye kupinda mukati memuviri wese wesimbi. Nenzira iyi, zinc inosangana nesimbi yose. Simbi iri mukati mesimbi inotanga kupindirana ne zinc, ichiita zinc-iron intermetallic coating. Kudivi rekunze, yakanatswa zinc coating inoiswa.
Inspection
Nhanho yekupedzisira ndeyekuongorora kupfekedza. Kuongororwa kwekuona kunoitwa kutarisa chero nzvimbo dzisina kuvharwa pamuviri wesimbi, sezvo chifukidzo hachizonamatira kune simbi isina kuchena. A magineti ukobvu gauge inogona zvakare kushandiswa kuona ukobvu hwekuputira.
2 Electro galvanizing
Electrogalvanized steel inogadzirwa kuburikidza ne electrochemical process. Muchiitiko ichi, simbi inonyudzwa mubhati ye zinc, uye magetsi emagetsi anopfuura nawo. Iyi nzira inozivikanwawo se electroplating.
Pamberi pegadziriro ye electrogalvanizing, simbi inofanira kucheneswa. Pano, zinc inoshanda seanode kuchengetedza simbi. Pa electrolysis, zinc sulfate kana zinc cyanide inoshandiswa se electrolyte, nepo cathode inodzivirira simbi kubva mukuora. Iyi electrolyte inoita kuti zingi irambe iri pamusoro pesimbi sejira. Iyo yakareba iyo simbi inonyudzwa mubhati ye zinc, iyo inowedzera kuvhara.
Kuwedzera kusadzivirirwa nekuora, mamwe majasi ekushandura anoshanda zvakanyanya. Iyi nzira inoburitsa imwezve zinc uye chromium hydroxides, zvichikonzera kutaridzika kwebhuruu pamusoro pesimbi.
3 Zinc Kupinza
Zinc plating inosanganisira kugadzira zinc coating pamusoro pesimbi kana simbi kudzivirira ngura yesimbi.
Mukuita uku, simbi inoiswa mumudziyo une zinc, iyo inobva yavharwa uye inopisa kusvika kune tembiricha iri pasi pekunyungudika kwe zinc. Mhedzisiro yekuita uku ndiko kuumbwa kwezinc-iron alloy, ine yakasimba yekunze dhizaini yezinc yakachena inonamatira kune pamusoro pesimbi uye ichipa kwakakosha kushora. Uku kupfekedza zvakare kunofambisa zvirinani kunamatira pendi pamusoro.
Kune zvinhu zvidiki zvesimbi, zinc plating ndiyo yakanyanya kunaka nzira. Iyi nzira inonyanya kukodzera zvikamu zvesimbi zvisina kuumbwa, sezvo kunze kwekunze kunogona kutevera nyore muenzaniso wesimbi yepasi.
4 Kupfapfaidza Simbi
Musimbi yekupfapfaidza zinc plating process, magetsi anochajiswa kana atomize yakanyungudutswa zinc zvimedu zvinopfapfaidzwa pamusoro pesimbi. Kuita uku kunoitwa uchishandisa pfuti yekupfapfaidza ruoko kana murazvo chaiwo.
Usati waisa zinc coating, zvose zvinosvibisa, zvakadai sezvisingadikanwi pamusoro pemvura, mafuta, uye ngura, zvinofanira kubviswa. Mushure mekunge nzira yekuchenesa yapera, maatomu akanyungudutswa zinc particles anopfapfaidzwa panzvimbo yakaoma, apo anoomesa.
Iyi simbi yekupfapfaidza yekupfapfaidza nzira ndiyo yakanyanya kufanira kudzivirira kusvuura uye kubhururuka, asi haina kunaka pakupa kwakakosha kuomarara.
Zinc coating inogara kwenguva yakareba sei?
Nezvekusimba, zvinowanzoenderana nekukora kwe zinc coating, pamwe nezvimwe zvinhu zvakaita serudzi rwenzvimbo, rudzi rwe zinc coating inoshandiswa, uye kunaka kwependi kana kupfapfaidza. Iyo yakakora iyo zinc coating, iyo yakareba hupenyu hurefu.
Hot-dip galvanizing vs. cold galvanizingKupisa-dip galvanized coatings anowanzo kusimba pane anotonhora emarata machira nekuti anowanzo kukora uye akasimba. Kupisa-dip galvanizing kunosanganisira kunyudza simbi muzinc yakanyungudutswa, nepo nenzira inotonhora yekuisa galvanizing, imwe kana maviri layer anopfapfaidzwa kana kubhurashwa.
Panyaya yekusimba, kupisa-dip galvanized coatings inogona kugara makore anopfuura makumi mashanu zvisinei nemamiriro ekunze. Kusiyana neizvi, kutonhora-kunyura galvanized coatings kazhinji kunongotora mwedzi mishoma kusvika kumakore mashoma, zvichienderana nekukora kwekuvhara.
Pamusoro pezvo, munzvimbo dzinoparadza zvakanyanya senge zvigadziriso zvemaindasitiri, hupenyu hwema zinc coatings hunogona kushomeka. Naizvozvo, kusarudza machira emhando yepamusoro eZinc uye nekuachengeta kwenguva yakareba kwakakosha pakuwedzera dziviriro kubva mukuora, kupera, uye ngura.
