1.Dab tsi yog lub hauv paus ntsiab lus ntawm kev khoov ua ntej-coated steel coils?
Txhua qhov kev txiav txim siab hauv cov txheej txheem dabtsi yog khoov tig ib ncig ntawm lub hauv paus ntsiab lus: txo qis kev puas tsuaj rau cov txheej txheem organic. Thaum cov txheej txheej tawg, cov dej noo thiab cov pa oxygen tuaj yeem nkag mus rau hauv cov kab nrib pleb, ua rau cov hlau hauv qab thiab ua rau xeb los ntawm sab hauv.
2.Dab tsi yuav tsum tau sau tseg txog kev taw qhia ntawm kev khoov?
Ua ntej kev khoov sab nraud: Khoov yuav tsum tau ua kom ze li sai tau rau qhov kev taw qhia dov (piv txwv li, qhov ntev kev taw qhia) ntawm lub pre-coated coil. Hauv lwm lo lus, txoj kab khoov yuav tsum yog perpendicular mus rau dov kev taw qhia.
Zam kev khoov ntev: Tsis txhob khoov raws qhov dav kev taw qhia ntawm lub pre-coated coil (ie, perpendicular mus rau dov kev taw qhia) kom ntau li ntau tau.
Yog vim li cas: Thaum lub sij hawm dov, cov nplej ntawm pre-coated substrate (feem ntau yog galvanized ntawv) muaj ib qho kev taw qhia. Lateral dabtsi yog khoov muab ductility zoo dua thiab txo qhov muaj feem ntawm txheej txheej tawg.
3.Yuav xaiv lub vojvoog dabtsi yog khoov?
Lub hauv paus ntsiab lus: Qhov loj dua qhov khoov vojvoog, qhov zoo dua. Lub vojvoog loj dua txo cov kev ntxhov siab ntawm cov txheej txheej, tiv thaiv microcracks hauv txheej.
Yam tsawg kawg Bending Radius: Qhov tshwj xeeb yam tsawg kawg yog dabtsi yog khoov vojvoog nyob ntawm cov khoom siv substrate thiab thickness, nrog rau hom thiab thickness ntawm txheej.
Substrate Influence: Kub-dip galvanized substrates muaj ductility zoo dua aluminized zinc substrates, tso cai rau me me dabtsi yog khoov radii. Lub thicker lub substrate, qhov loj qhov yuav tsum tau yam tsawg kawg nkaus khoov vojvoog.
Coating Influence: PVC plastisol coatings (thicker, feem ntau siv hauv cov khoom siv hauv tsev) yog qhov hloov tau yooj yim dua thiab muaj zog tiv thaiv kev sib tsoo tawg dua li cov txheej polyester (thinner, feem ntau siv hauv kev tsim kho).
Cov Txheej Txheem Kev Ua Haujlwm: Nco ntsoov sab laj cov ntaub ntawv kev qhia los ntawm cov xim -coated coil chaw tsim tshuaj paus, uas yuav qhia meej txog qhov tsawg kawg nkaus tso cai bending vojvoog rau cov khoom (feem ntau qhia raws li ntau yam ntawm daim ntawv tuab, xws li 1.5t, 2t, thiab lwm yam).
4.Dab tsi yuav tsum tau xav txog thaum xaiv cov pwm thiab kho cov cuab yeej?
Tuag Nto tiav: Ib tus du, huv si, xeb -dawb, thiab burr- dawb dabtsi yog khoov tuag yuav tsum tau siv. Txhua yam tsis xws luag hauv qhov tuag yuav raug imprinted rau ntawm txheej txheej, ua rau kev puas tsuaj.
Zam Lub kaum ntse ntse: Lub hau ntawm lub taub hau tuag yuav tsum muaj lub kaum sab xis uas tsim nyog; tsis txhob siv cov ntse tuag ntau dhau.
Kev kho qhov siab: Siv qhov qis tshaj qhov tuaj yeem khoov siab thaum tuav lub kaum sab xis kom raug. Kev kub siab ntau dhau yuav ua rau cov txheej txheem loj heev.
Kev Tswj Ceev: Siv cov khoom sib xws, qeeb khoov ceev. Kev nrawm nrawm yuav cuam tshuam rau txheej txheej, ua rau muaj kev pheej hmoo ntawm kev tawg.
5.Dab tsi yog cov teeb meem thiab kev daws teeb meem?
Teeb meem: Cov kab nrib pleb zoo los yog "txiv kab ntxwv tev" tshwm sim nyob rau hauv txheej ntawm khoov.
Ua rau: Lub vojvoog dabtsi yog khoov me me dhau, dhau ntawm cov txheej txheem yooj yim.
Kev daws: Ua kom lub vojvoog khoov; xaiv cov txheej uas muaj kev hloov pauv zoo dua (xws li siab -cov ntaub ntawv polyester, PVC yas xim, thiab lwm yam).
Teeb meem: Txheej peels tawm ntawm khoov.
Ua rau: ntxhib los yog puas pwm; bending siab ntau dhau; incorrect embossing phaj orientation.
Kev daws: Tshawb xyuas thiab txhuam cov pwm; txo qhov siab; xyuas kom lub ntsej muag embossed sab nraud thaum khoov.
Teeb meem: Whitening los yog hloov nyob rau hauv gloss ntawm khoov.
Ua rau: Cov txheej txheej tau dhau mus, ua rau microscopic deformation.
Kev daws: Qhov no kuj yog ib qho cim ntawm qhov tsis txaus khoov vojvoog; lub vojvoog kuj yuav tsum tau nce ntxiv.
