Kupisa-dip galvanizing ndiyo imwe yenzira dzakakosha dzekudzivirira ngura dzinowanzoshandiswa pakurapa kwepamusoro kwesimbi. Munzvimbo ine corrosion, kukora kwegororo resimbi yesimbi ine simba rakananga pakudzivirira kusimba. Pasi pemamiriro akafanana esimba rekubatanidza, ukobvu hwejasi (huwandu hwekunamatira) hwakasiyana, uye nguva yekudzivisa ngura yakasiyanawo. Zinc ine yakanyanya kunaka kuita sechinhu chinodzivirira chesimbi grating base. Iyo electrode simba rezinc yakaderera pane iyo yesimbi. Pamberi pe electrolyte, zingi inova anode uye inorasa maerekitironi uye corrodes zviri nani, nepo chigadziko chesimbi chinova cathode. Inodzivirirwa kubva pakuora nekudzivirira kwe electrochemical kwegirodhi yegalvanized. Zviripachena, iyo yakatetepa iyo yekupfeka, iyo ipfupi nguva yekudzivirira ngura, uye nguva yekudzivirira yekugara inowedzera sezvo ukobvu hwekuputira hunowedzera. Nekudaro, kana ukobvu hwekufukidzira hwakanyanya kukora, simba rekubatanidza pakati pekupfekedza uye simbi substrate inodonha zvakanyanya, izvo zvinoderedza ngura yekudzivirira nguva uye haina mari-inoshanda. Naizvozvo, pane optimal value yehukobvu hwekufukidzira, uye hazvina kunaka kuve wakakora. Mushure mekuongorora, kune inopisa-dip galvanized simbi yekuisa plating zvikamu zveakasiyana maratidziro, iyo yakakwana yekupfekedza ukobvu ndiyo inonyanya kukodzera kuwana iyo yakareba yekudzivirira ngura nguva.
Nzira dzekuvandudza kukobvu kwekuputira
1. Sarudza yakanakisa galvanizing tembiricha
Maitiro ekudzora tembiricha ye galvanizing yesimbi grating yakakosha kuve nechokwadi uye kuvandudza kunaka kwekupfeka. Mushure memakore ekudzidzira kugadzira, isu tinotenda kuti zvakanaka kudzora kupisa-dip galvanizing tembiricha pa470 ~ 480 ℃. Kana ukobvu hwechikamu chakaputirwa chiri 5mm, ukobvu hwekuputira hunosvika 90 ~ 95um (tembiricha yakadzika 21 ~ 25 () Panguva ino, kupisa-kunyura-yakagadzika simbi grating inoedzwa necopper sulfate nzira. Mhedzisiro inoratidza kuti: iyo yekupfekedza inonyudzwa kwekanopfuura kanomwe pasina kufumura iyo iron matrix yakawanda isina madhigirii 1 nguva; Kana iyo zinc kunyudzwa tembiricha iri 455 ~ 460 ℃, ukobvu hwekuputira hwakapfuura kukosha kwakaringana panguva ino, kunyangwe iyo yekuvharisa yunifomu mhinduro yakanaka (kazhinji inonyudzwa kwekanopfuura ka8 pasina kufumura matrix), nekuda kwekuwedzera kwezinc yemvura viscosity, iyo bvunzo yekunyungura haina kujeka, iyo inogoneka bvunzo haina kujeka. delamination panoitika tembiricha yekunyudzwa kwezinki iri 510 ~ 520 ℃, ukobvu hwekufukidzira huri pasi pehukoshi hwakakwana (kazhinji husingasviki 60um huwandu hwezviyero zvakafanana ndeye 4 kunyudzwa kufumura matrix, uye kuramba kwecorrosion hakuna vimbiso.
2. Dzora kukurumidza kusimudza kwezvikamu zvakaputirwa. Iko kumhanya kwekusimudza simbi grating yakapfava zvikamu kubva kune zinc fluid ine yakakosha pesvedzero pahukobvu hwekuputira. Kana iyo yekusimudza kumhanya ichikurumidza, ipapo Iyo galvanized layer yakakora. Kana kukurumidza kusimudza kunonoka, kupfeka kunenge kwakaonda. Nokudaro, kukurumidza kusimudza kunofanira kunge kwakakodzera. Kana ikanyanya kunonoka, iyo iron-zinc alloy layer uye iyo yakachena zinc layer ichapararira panguva yekusimudza simbi grating yakapfava zvikamu, zvekuti iyo yakachena zinc layer inenge yakanyatso kushandurwa kuita alloy layer, uye grey-nyota firimu inoumbwa, iyo inoderedza kukotama kuita kwejasi. Mukuwedzera, kunze kwekuve yakabatana nekusimudza kukurumidza, zvakare yakanyatsobatana nekona yekusimudza.
3. Nyatsodzora nguva yekunyudza zinc
Zvinonyatso zivikanwa kuti ukobvu hwesimbi yekubikira simbi yakanangana neiyo zinc kunyudzwa nguva. Iyo zinc kunyudzwa nguva inonyanya kusanganisa iyo nguva inodiwa yekubvisa iyo plating rubatsiro pamusoro pezvikamu zvakapfava uye nguva inodiwa kupisa zvikamu zvakapfava kune zinc yemvura tembiricha uye kubvisa zinc ash pamvura yemvura mushure mekunyudzwa. Mumamiriro ezvinhu akajairwa, nguva yekunyudzwa kwezinki yezvikamu zvakaputirwa inodzorwa kusvika kuhuwandu hwenguva iyo maitiro pakati pezvikamu zvakaputirwa uye zinc fluid inopera uye zinc ash pamvura inobviswa. Kana nguva yacho ipfupi, kunaka kwesimbi grating plated parts haigoni kuvimbiswa. Kana iyo nguva yakareba kwazvo, hupamhi uye brittleness yekuputira huchawedzera, uye kushorwa kwekupotera kwejira kuchaderedzwa, izvo zvinokanganisa hupenyu hwebasa resimbi grating plated parts.
