1.Vim li cas galvanized coils haum rau hmoov txheej?
Zoo heev corrosion kuj: galvanized txheej nws tus kheej muab anodic xeb tiv thaiv. Txawm tias muaj me ntsis khawb, zinc nyiam corrodes, tiv thaiv cov hlau substrate, uas cuam tshuam rau tag nrho cov kev pab cuam lub neej ntawm cov khoom.
Smooth thiab tiaj tus substrate: Lub npoo du ntawm cov galvanized coil muab lub hauv paus zoo rau cov hmoov txheej, yooj yim ua tiav cov txheej txheem thiab du.
Lub zog siab thiab yooj yim ntawm kev ua: Cov hlau substrate muab lub zog, thiab cov galvanized coil yog ib qho yooj yim rau shear, punch, nias, khoov, thiab lwm yam kev ua, ua rau nws tsim nyog rau kev tsim ntau yam qauv.
2.Dab tsi yog lub hom phiaj thiab txoj kev ntawm degreasing thiab ntxuav?
Lub Hom Phiaj: Yuav kom tshem tawm cov kab mob kom huv si xws li cov roj dov, xeb -cov roj tiv thaiv, ntiv tes, thiab plua plav.
Txoj kev: Siv ib qho alkaline lossis nruab nrab degreaser los ntxuav los ntawm kev txau los yog soaking. Cov kauj ruam no yog qhov tseem ceeb; ib qho roj seem yuav ua rau txo qis txheej adhesion thiab pinholes.
3.Dab tsi yog cov kauj ruam koom nrog hauv kev txau?
Electrostatic hmoov txheej: Cov hmoov txheej tsis zoo yog siv rau qhov zoo ntawm qhov chaw ua haujlwm uas siv phom electrostatic tsuag.
High -kub curing: Lub coated workpiece yog muab tso rau hauv ib tug curing qhov cub thiab ci ntawm ib tug tshwj xeeb kub (feem ntau yog 160℃- 200 degree) rau ib lub sij hawm, ua rau cov hmoov yaj, theem, thiab cross-link los tsim cov txheej txheem tiv thaiv zaum kawg.
4.Peb yuav ntsib teeb meem dab tsi thiab cov kev daws teeb meem yog dab tsi?
Tsis zoo adhesion: Lub hauv paus ua rau tsis txaus pretreatment. Xyuas kom meej degreasing thiab ib tug uniform thiab zoo hloov dua siab tshiab txheej.
Pinholes: Feem ntau tshwm sim los ntawm cov kab ntawm cov roj seem lossis silicone ntawm qhov chaw. Kev txhim kho degreasing thiab rhiav kev tswj ib puag ncig yog xav tau.
Npuas lossis qhov: Tej zaum yuav tshwm sim los ntawm cov khoom seem ntawm cov pa roj lossis cov khoom paug tawm ntawm "zinc spangle" cov ciam teb ntawm cov txheej galvanized thaum lub sij hawm siab -kub curing. Xyuas kom tiav ziab tom qab pretreatment thiab xaiv hmoov nrog rau qhov tsim nyog curing kub.
Ntau dhau ntawm cov txiv kab ntxwv tev kev ntxhib los mos: Dhau li ntawm cov hmoov nws tus kheej thiab cov tshuaj tsuag, yog tias lub galvanized coil nto nws tus kheej muaj qhov hnyav "txiv kab ntxwv tev kev ntxhib los mos" (los ntawm cov zinc spangles loj), nws tseem yuav rov ua dua rau ntawm txheej txheej. Rau cov khoom uas yuav tsum tau ua siab zoo, galvanized coils nrog me me zinc spangles los yog du zinc spangles yuav tsum tau xaiv.
5.Koj muaj lus qhia dab tsi rau cov neeg yuav khoom lossis cov neeg siv khoom?
Kom meej meej cov kev cai: Qhia meej meej qhov kev npaj siv ib puag ncig thiab cov kev xav tau ntawm cov khoom kawg rau cov khoom siv galvanized coil thiab cov nroj tsuag txheej.
Xaiv cov substrate uas tsim nyog: Rau siab - cov khoom yuav tsum tau, ua qhov tseem ceeb galvanized coils nrog lub ntsej muag zoo (xws li, du nto) thiab me me zinc spangles.
Ntsuam xyuas cov txheej txheem: Xaiv cov txheej txheem txheej txheem nrog ua tiav thiab cov txheej txheem ua ntej cov kab ntau lawm thiab cov txheej txheem paub tab.
