Thawj 400 lub hauv paus ntawm pawg racks yog npaj rau kub-dipped galvanizing nto kho.Tus nqi tag nrho ntawm kev txiav txim yog 2000 lub hauv paus ntawm pawg racks.Hom racks no feem ntau yog siv rau hauv cov khoom noj txias txias, qhov kub thiab txias hauv warehouse feem ntau yog qis dua -18 ℃.
Hauv peb cov kab, muaj ob txoj hauv kev los kho qhov chaw, ib qho yog hmoov-txheej, lwm qhov yog galvanizing ua rau peb cov racks corrosion-resistant.Galvanizing muaj ob hom: txias galvanizing thiab kub-dipped galvanizing.Kub-dipped galvanizing uas yog siv rau hauv peb cov khoom lub sij hawm no muaj kev ua tau zoo ntawm corrosion-resistant dua hmoov-txheej thiab txias galvanizing.Thiab nws kuj yog qhov kim tshaj plaws piv nrog cov hmoov txheej thiab txias galvanizing.
Vim li cas thiaj kim?Hauv qab no yog cov txheej txheem ntawm kub-dipped galvanizing:
Kev npaj nto
Thaum cov hlau fabricated tuaj txog ntawm qhov chaw galvanizing, nws yog dai los ntawm cov hlau los yog muab tso rau hauv lub racking system uas tuaj yeem nqa thiab txav mus los ntawm cov txheej txheem los ntawm cov nyiaj siv ua haujlwm cranes.Cov hlau ces mus dhau ntawm peb cov kauj ruam tu;degreasing, pickling, thiab fluxing.Degreasing tshem tawm cov av, roj, thiab cov organic residues, thaum lub acidic pickling da dej yuav tshem tawm zeb nplai thiab hlau oxide.Cov kauj ruam kawg ntawm kev npaj saum npoo, fluxing, yuav tshem tawm cov oxides uas tseem tshuav thiab muab cov hlau nrog txheej tiv thaiv kom tsis txhob muaj cov oxide ntxiv ua ntej galvanizing.Kev npaj kom zoo yog qhov tseem ceeb, vim tias zinc yuav tsis hnov mob nrog cov hlau tsis huv.
Galvanizing
Tom qab kev npaj nto, cov hlau yog dipped nyob rau hauv lub molten (830 F) da dej ntawm tsawg kawg yog 98% zinc.Cov hlau yog qis dua rau hauv lub hwj ntawm lub kaum sab xis uas tso cai rau huab cua kom dim ntawm cov duab tubular lossis lwm lub hnab, thiab cov zinc ntws mus rau hauv, tshaj, thiab dhau los ntawm tag nrho cov khoom.Thaum immersed nyob rau hauv lub kettle, cov hlau nyob rau hauv cov hlau metallurgically reacts nrog zinc los tsim ib tug series ntawm zinc-hlau intermetallic txheej thiab ib txheej txheej ntawm ntshiab zinc.
Kev tshuaj xyuas
Cov kauj ruam kawg yog kev tshuaj xyuas cov txheej txheem.Kev txiav txim siab zoo ntawm cov txheej txheej tuaj yeem ua tiav los ntawm kev tshuaj xyuas qhov muag, vim tias zinc tsis hnov mob nrog cov hlau tsis huv, uas yuav tawm hauv qhov chaw tsis muaj coated.Tsis tas li ntawd, qhov ntsuas qhov sib nqus hlau tuaj yeem siv los txheeb xyuas cov txheej txheej tuab ua raws li cov lus qhia tshwj xeeb.
