1. Khi {{- dip galvanized chev daim ntawv ib qho zinc txheej los ntawm kev tso nyiaj electrolytic. Qhov no muaj dab tsi ntawm kev ua tiav?
Ncaj qha txo ua ntej -}} kho cov kauj ruam ua ntej tha xim.
Vim tias thaj chaw saum npoo av thiab me ntsis - dip galvanized ua ntej kev sib tsoo, nrog kev sib tsoo, thiab phosphating, thiab phosphating, thiab phosphating, thiab phosphating, thiab cov duab. Txias - dip galvanized chev, ntawm qhov tou ua yeeb yaj kiab, thiab cov pleev zaj nkauj kom du, Qhov no ua rau nws haum rau kev siv xws li cov khoom siv hauv tsev thiab lub cev lub cev topcoats. Qhov no tsis yog txo cov nqi thiab cov nqi, tab sis kuj tseem yuav zam zinc txheej poob tshwm sim los ntawm kev sib tsoo, ua kom corrosion tsis kam.
Txhim kho txoj kev sib thooj hauv precision stamping
Nyob rau hauv precision stamping applications xws li cov ntaub ntawv hluav taws xob me me, cov kev sib txuas ncaj qha rau cov kev sib txuas ntawm cov tuag thiab cov hlau txaij. Spangle Protrusions nyob rau saum npoo tau yooj yim coj mus rau uneven hauv zos lub zog thaum lub caij stamp, ua rau muaj kev sib txawv thiab kev sib txawv. Lub tiaj tiaj ntawm txias - dip galvanized coil enjecticent tuag siab, kom ntseeg qhov ntev nyob rau hauv batch stamping thiab txo cov seem stamping thiab txo cov seem.
2.Yog li cas ib txheej zinc nyias nyias muaj ntawm khoov lossis sib sib zog nqus cov khoom?
Tsis muaj kev pheej hmoo ntawm zinc tev thaum khoov.
Thaum lub sijhawm rov ua dua 90℃/ 180℃dabtsi yog khoov ntawm cov txheej txheem txee thiab cov khoom tawg ntawm ntau dua 20%), tiv thaiv kev tawg lossis tev vim zinc brittleness. Hauv kev sib piv, cov tuab tuab siv zinc txheej ntawm kub- dip galvanized steel tau yooj yim tawg ntawm subformation ntawm substrate thiab zinc txheej thaum khoov. Qhov nyias txheej yas ntawm cold- dip galvanized steel ua kom muaj kev lag luam, tshem tawm qhov xav tau ntawm kev rov pleev xim ntxiv. Sib sib zog nqus teeb cov txheej txheem yog tsawg tus nquag mus rau "zinc txheej embrittlement thiab tawg."
Hauv cov ntawv thov sib sib zog nqus, xws li lub tub yees rooj lub qhov rooj thiab tsheb lub qhov rooj sab hauv, lub workpiece undergoes tensile deformation. Yog tias cov txheej zinc txheej dhau yog cov tuab tuab heev lossis muaj cov khoom tsis zoo, nws tuaj yeem cais tawm ntawm cov chaw (xws li cov npoo thiab cov ceg ntoo ntawm cov vaj huam sib luag). Txawm li cas los xij, cov txheej yas nyias ntawm cov khaub thuas - dip galvanized chev cia kom nruj me ntsis, ncab synchronously nrog nws. Lub Zinc Txheej uas tau nqus tau qee qhov kev ntxhov siab tensile, tiv thaiv zinc txheej tsis ua haujlwm tom qab kev kho mob tom qab.
3.Qhov yog lub corrosion tsis kam tom qab vuam / shearing?
Vuam ua cov lag luam ua haujlwm qis qis, thiab cov ntaub ntawv hauv kev corrosion - tiv taus thiab kho tau yooj yim.
Hauv kev tawm tsam vuam / arc vuam ntawm cov hlau qauv nkhaus, cov ntaub pua nyias txuas ntxiv dua li cov tuab tuab dua li txheej kub. Qhov no txo qis zinc fum patfasting thaum vuam (tiv thaiv kev noj qab haus huv weldosity) thiab tiv thaiv weld pority (kom meej weld zog). Tsis tas li ntawd, tom qab vuam, tsuas yog lub zos passivation los yog kov -}}} yuav tsum tau nyob ntawm Weld Seam (nthuav tawm cov khoom siv weld (nthuav tawm cov khoom siv Qhov no, ua ke nrog cov khaub thuas - dip galvanized chev, muab kev tiv thaiv ua ke rau cov khoom lag luam loj hlob thiab txo cov nqi {6} Taug kev cov nqi kho. Kev txiav yog tsawg dua li raug rau xeb tom qab shearing / slitting. Thaum lub sij hawm shearing / slitting txheej txheem rau nqaim nqaim ntawm cov khoom kho vajtse thiab cov khoom siv hluav taws xob, cov khoom siv hauv paus yog nthuav tawm ntawm kev txiav. Txawm li cas los xij, qhov passivation zaj duab xis ntawm cold- dip txheej ntawm kev txiav), thiab cov neeg passive nyias nyias "tshuaj tiv thaiv kev txiav" tiv thaiv kev txiav. Piv rau kub - dip galvanized chrvanized kev siv xeb, txias}}}} lub teeb, txhim kho kev yooj yim.
4.What yog lub siab- precision thiab tsawg- Tsis Tuag Galvanized Coils?
Siab shearing / sritting precision thiab burr - dawb ua tau.
Tsawg - Cov hlau me me muaj qhov nyuaj (huv qis dua (HV tsawg dua lossis sib npaug ntawm 150), uas txo cov cuab yeej thaum lub sijhawm shearing. Nws nruj ntev ntev thev taus puas du, burr {- dawb npoo rau nqaim rau nqaim (piv txwv li 50 hli) tom qab slitting. Qhov no ua rau nws zoo rau kev ua cov khoom siv kho me me thiab cov pob tw hluav taws xob, tshem tawm qhov xav tau rau kev tshem tawm ntawm Burr tshem tawm thiab txo qis cov kauj ruam.
Qhov seem ruaj khov rau qhov tsis zoo rau kev khoov.
Rau cov ntawv thov uas yuav tsum tau kho cov ces kaum (piv txwv li 90 degree) xws li cua txias tshaj tawm (lub tshuab hluav taws xob tsawg dua lossis sib npaug rau 2%). Nws qhov chaw siab siab tau ua kom muaj cov ces kaum sib npaug los ntawm kev ua kom sib luag, kev sib txawv, thiab kev txhim kho txuas ntxiv.
5.Qhov dab tsi yog cov tub ntxhais ua haujlwm tseem ceeb ntawm kev ua tau zoo thiab ua kev yoog tau?
Du nto → haum rau kev pleev xim thiab precision stamping (txo ua ntej - kev kho);
Nyias zinc txheej + siab ductility → Haum rau dabtsi yog khoov thiab sib sib zog nqus duab (zam zinc Txheej tsis ua hauj lwm);
Metallurgical bonding + passivation zaj duab xis 00 haum rau vuam thiab shearing (ua kom corrosion tsis kam ua);
Mos Substrate + siab siab → haum rau precision shearing thiab dabtsi yog khoov (kom ua tau yog qhov tseeb).
