1.Do lub peev xwm deformation ntawm txheej thiab substrate sib phim?
Substrate (Steel Sheet): Muaj cov ductility zoo heev, tshwj xeeb tshaj yog txias -cov ntawv steel dov thiab cov ntawv hlau galvanized ntawm "qib stamping" lossis "qib kos duab sib sib zog nqus," uas yog tsim los tiv thaiv cov yas deformation hnyav (xws li kev sib sib zog nqus nqus thiab ncab).
Txheej (Organic Txheej): Qhov tseem ceeb ib txheej ntawm "yas xim zaj duab xis" adhered rau cov ntawv hlau. Nws yooj yim thiab ductility yog qis dua cov hlau substrate. Thaum daim ntawv yog sib sib zog nqus nqus, cov txheej yog raug rau stretching hnyav, ua rau nws muaj feem cuam tshuam rau cov nram qab no tsis ua hauj lwm:
Cracking: Cov txheej tsis tuaj yeem txuas nrog lub substrate, ua rau macroscopic lossis microscopic tawg.
Peeling: Qhov adhesion ntawm cov txheej thiab cov substrate raug cuam tshuam, ua rau thaj tsam loj lossis loj -tev.
Poob Gloss / Discoloration: Txawm tias tsis muaj qhov pom tseeb tawg, txheej txheej yuav plam nws cov gloss, nthuav tawm "txiv kab ntxwv tev" cov nyhuv, lossis ua xim tsis sib xws vim kev ncab ntau dhau.
2.Yuav ua li cas siab zoo siab - txheej txheej ua tau zoo?
Resin System: Siv cov resins nrog zoo ductility, xws li plastisol, siab -ductility polyester, thiab polyurethane. Cov txheej txheem no tuaj yeem tiv taus lub zog tensile txog li 15% lossis siab dua yam tsis muaj kev tawg, thaum cov txheej txheem polyester zoo tib yam tuaj yeem ncav cuag tsawg dua 5%.
Crosslinking thiab Flexibility: Los ntawm kev hloov kho tshuaj, kev hloov pauv tau zoo dua qub thaum tuav cov tawv tawv thiab huab cua tsis kam.
Adhesion: Ib qho tshwj xeeb primer system xyuas kom meej tias cov txheej tseem ruaj khov txawm tias tom qab deformation.
3.Dab tsi yog qhov kev sim ua haujlwm nruj?
T-kuaj khoov: Ntsuas qhov adhesion thiab tawg ntawm txheej tom qab ntse khoov.
Kev xeem Cupping: Ntsuas qhov ua tau zoo tshaj plaws ntawm cov txheej txheem nyob rau hauv biaxial tensile deformation, qhov taw qhia tseem ceeb rau kev ntsuas nws qhov tsim nyog rau stamping.
Impact test: Simulates qhov kev ntxhov siab thaum lub sij hawm tsim.
4.Dab tsi yog cov lus xaus thiab cov lus pom zoo?
Ordinary pre-coated steel coils rau kev tsim kho: Haum rau kev khoov yooj yim thiab yob txoj kev, tab sis tsis tsim nyog rau kev sib sib zog nqus nqus, ncab, bulging, thiab lwm yam txheej txheem uas cuam tshuam loj heev deformation.
Tshwj xeeb ua ntej-coated steel coils: tuaj yeem siv los tsim cov khoom stamped nrog qhov tob, tab sis tsis yog qhov hnyav, xws li cov rooj plaub hauv computer, cov khoom siv vaj huam sib luag, cov teeb ci, thiab cov ntaub ntawv txee. Txawm li cas los xij, txawm tias tshwj xeeb ua ntej-coated steel coils yog qhov tsis tsim nyog rau "kev kos duab sib sib zog nqus" qhov uas yuav tsum tau ncab heev, xws li tsheb roj tso tsheb hlau luam thiab stainless hlau cookware.
5.Yog tias koj yuav tsum siv cov xim -cov ntaub ntawv coated rau cov khoom stamped, koj yuav tsum ua li cas?
Txhais cov txheej txheem yuav tsum tau ua: Txiav txim siab qhov tseem ceeb xws li qhov siab tshaj plaws deformation tus nqi, ncab qhov tob, thiab khoov vojvoog ntawm cov khoom.
Nrhiav ib tus kws tshaj lij: Hu rau ua ntej-coated coil manufacturers, tsis zoo ib yam architectural pre-coated ntawv lwm tus neeg. Qhia meej meej koj cov txheej txheem stamping yuav tsum tau ua.
Thov thiab kuaj cov qauv:
Thov tus neeg muag khoom muab cov qauv ntawm "pre-coated coil" haum rau stamping.
Ua cov kev sim stamping tiag ntawm koj cov pwm; qhov no yog tib txoj kev txhim khu kev qha los xyuas qhov ua tau. Tshawb xyuas cov txheej txheem kom tawg, tev, thiab poob ntawm gloss.
Paub meej txog Cov Txheej Txheem: Thov tus neeg muag khoom muab cov ntaub ntawv tseem ceeb xws li cov khoom siv tus nqi cupping, T- khoov kev ua tau zoo, thiab txheej elongation.
