1.What yog qhov kev cuam tshuam ntawm zinc txheej ntsig txog kev tsis taus?
Zinc Delamination / tev:
Thaum lub sij hawm poob nqis stamping thiab dabtsi yog cov txheej txheem dabtsi, cov txheej zinc tau yooj yim tev tawm ntawm cov ntug dej nrawm nrawm raws li kev sib cuag nrog huab cua thiab ya raws. Qhov no tuaj yeem ua kom cov khoom lag luam luv luv hauv cov ntawv thov xws li cov khoom lag luam thiab cov qauv hlau. Hauv vaj tsev, cov peeting zinc txheej kuj tseem tuaj yeem paug cov khoom siv ua thiab nce cov nqi huv.
Uneven / tshaj plinc Txheej Zinc Txheej Thickness:
Thaj chaw nrog thinner zinc txheej muaj cov tshuaj tiv thaiv corrosion tsis txaus. Cov khoom siv hauv dej (xws li cov kav dej thiab sab nraum zoov tus neeg tiv thaiv kev ua kom muaj zog (piv txwv li kev phom sij) lossis kev puas tsuaj kom zoo nkauj
Ntsuas / Pinholes:
Cov cheeb tsam dag kom tsis txhob muaj kev tiv thaiv ntawm zinc txheej, ua ib qho "pib" rau kev xeb. Thaum siv, xeb tuaj yeem kis tau los ntawm cov ntsiab lus uas ploj lawm rau cov khoom lag luam hauv qab dej (piv txwv li, cua txias sab nraum zoov thiab ntim). Thaum muaj mob hnyav, qhov no tuaj yeem ua rau pom zoo (piv txwv li, dej caw).
2.What yog qhov cuam tshuam ntawm qhov xwm txheej saum npoo?
Khawb / dents:
Thaum siv nyob rau hauv cov khoom siv hauv tsev (xws li tshuab ntxhua khaub ncaws (xws li tshuab ntxhua khaub ncaws) thiab xaim hluav taws xob tuaj yeem hle cov khoom lag luam zoo nkauj, ua rau kev ua kom muaj kev cuam tshuam lossis tsis tuaj yeem ua rau muaj kev cuam tshuam. Thaum siv rau ntawm archective zoo nkauj panels (xws li kab hlau rhuav thiab nthab), lawv tuaj yeem cuam tshuam rau tag nrho cov tiav thiab nce cov nqi tag nrho.
Pits / Zinc Ntsiab Lus:
Qhov pitting saum npoo lossis zinc hais tau ua rau cov xim tsis sib xws thaum lub sijhawm poob qis, ua rau "pinholes" lossis "txo cov txheej adhesion. Piv txwv li, tom qab pleev xim lub cev tsheb, qhov chaw muaj cai tau yooj yim ua rau pleev xim rau tev, ua rau xeb. Hauv cov khoom siv hauv tsev, txheej tsis ncaj tuaj yeem ua rau muaj kev sib txawv, cuam tshuam kev lag luam.
Roj stains / oxidation discoloration:
Residual roj stains ntawm qhov chaw tuaj yeem tiv thaiv cov xim pleev xim tsis zoo thaum lub sijhawm ua haujlwm qis, ua rau "craters." Oxidation discoloration (xws li blackening lossis daj) tuaj yeem cuam tshuam rau cov khoom lag luam zoo li qub. Thaum siv nyob rau hauv high-end zoo nkauj cov ntawv thov (xws li cov rooj tog vaj huam sib luag), qhov no tuaj yeem txo kev sib tw ua lag luam.
3.Qhov twg yog qhov cuam tshuam ntawm cov qauv tsis xws luag?
Scissor khoov / wavy npoo:
Thaum lub sijhawm poob thiab vuam, cov ntawv hlau tsis tuaj yeem ua raws li tiaj tus, ua rau muaj kev sib txawv lossis kev sib txawv ntawm cov pob qij txha. For example, when galvanized sheet metal for construction is welded to steel structures, wavy edges can lead to weak welds and pose a safety hazard. Thaum siv cov pob tsheb sib nraus, scissor khoov tuaj yeem ua rau muaj pwm nce ntxiv thiab txawm muab tso rau hauv.
Cov ntawv tsis zoo rau cov hlau) hlau puab (xws li Chaw thiab ntug vuag):
Rau qhov machision machines (xws li xws li cov cuab yeej siv hluav taws xob thiab cov cuab yeej siv hluav taws xob), cov ntawv tsim txom hauv hlau yuav ua rau muaj kev sib txawv ntawm cov kev sib txawv tom qab stamping, ua kom sib dhos ua tsis tau. Rau yeeb nkab dov, kev hloov pauv tsis zoo tuaj yeem cuam tshuam rau kev sib txuas ntawm kev sib txuas (piv txwv li, xau hauv kav dej).
4.What yog qhov cuam tshuam ntawm cov khoom siv tshuab hluav taws xob?
Ntau dhau / tsis txaus siab:
Ntau zog ua rau muaj peev xwm ua rau tawg thiab chipping hauv cov txheej txheem downstream stamping (piv txwv li lub qhov rooj tsheb sib tsoo tawg thaum lub sijhawm stamping); Tsis txaus siab ua rau muaj kev sib txawv (piv txwv li, khoom siv, khoom siv bending hauv qab thauj), cuam tshuam cov khoom ua haujlwm.
Cov khoom tsis txaus ntseeg tensile (piv txwv li, qis elongation):
Thaum siv nyob rau hauv cov khoom hauv dej ntws hauv cov khoom lag luam uas yuav tsum tau ua kom sib sib zog nqus hlau thaum lub sij hawm cov khoom tso tawm tsheb hlau thiab tseem muaj cov khoom siv hluav taws xob ntau dua (piv txwv li, cov hlab ntsha siab ntau lawm).
Suav / tawg:
Suav nrog lossis cov kab nrib pleb hauv lub substrate tuaj yeem nthuav tawm thaum lub sij hawm nqes hav dauv thiab khoov, ua rau ib feem breakage. Piv txwv li, thaum vuam vuam hlau kav teb rau kev tsim kho, kab nrib pleb tuaj yeem ua rau tsis muaj weld muaj zog weld thiab muaj kev pheej hmoo ntawm kev vau. Zais cov kab nrib pleb hauv kev tsav tsheb hauv tsheb tuaj yeem ua rau kev tawg sai thaum lub sijhawm ua haujlwm siab, ua rau muaj kev sib raug zoo.
5.Txoj kev cuam tshuam zoo tsis xws luag zoo
Cov kev tsis xws luag zoo hauv galvanized coils tuaj yeem sib kis mus rau cov dej kawg, ua rau muaj kev cuam tshuam nrog kev nyab xeeb rau kev nyab xeeb. Qhov no tseem tuaj yeem ua rau muaj kev ua haujlwm ntau dua thiab cov ntawv sau rau hauv cov tuam txhab poob qis, ua rau poob kev ua lag luam. Yog li ntawd, cov khoom siv hauv qab dej (xws li cov khoom siv hluav taws xob, cov khoom siv hauv tsev, thiab kev tsim kho) feem ntau muaj cov tshuaj tiv thaiv lub Hoobkas kom txo cov kev pheej hmoo no.
