Cov ntawv pov thawj zoo dab tsi kuv tuaj yeem thov los ntawm cov chaw tsim khoom thaum yuav DC03 coil?
A: Koj tuaj yeem thov cov ntawv pov thawj xws li IATF 16949, ISO 9001, SGS, thiab CE. Cov ntawv pov thawj no ua kom cov hlau zoo thiab ua raws li cov txheej txheem ntau lawm.
Dab tsi yog qhov sib txawv hardness ntawm DC03 kauj?
A: Lub hardness feem ntau tswj ntawm 65 thiab 85 HRB. Yog hais tias qhov hardness tshaj tus qauv, nws yuav cuam tshuam rau vuam thiab stamping kev ua tau zoo. Nws yog ib qho tsim nyog los xyuas seb cov qoob loo loj npaum li cas thiab cov tshuaj muaj pes tsawg leeg ua tau raws li cov qauv hauv kev tsim khoom.
DC03 kauj tuaj yeem khoov tau? Puas muaj kev txwv rau qhov siab tshaj plaws dabtsi yog khoov thickness?
A: Khoov yog ua tau. DC03 coils nrog lub thickness tsis tshaj 1.5mm qhia kev ruaj ntseg zoo dua thaum khoov. Rau cov phaj tuab, cov txheej txheem yuav tsum tau ua ua ntej.
Puas yog DC03 coil yuav tsum tau kho qhov chaw thaum siv cov txheej txheem tshuaj tsuag?
A: Yog lawm, cov roj av thiab oxide nplai feem ntau yuav tsum tau muab tshem tawm. Qhov no tuaj yeem ua tiav los ntawm pickling, sib tsoo, thiab lwm yam. Pretreatment txhim kho qhov adhesion ntawm txheej thiab cov hlau, tiv thaiv txheej txheej txheej. Dab tsi cuam tshuam rau tus nqi ntawm DC03 kauj?
A: Tus nqi cuam tshuam los ntawm cov khoom xws li tus nqi ntawm cov hlau ore raw, kev siv thev naus laus zis (xws li, txawm tias nws yog galvanized), qhov tshwj xeeb thiab qhov ntev, kev txiav txim kom muaj nuj nqis, thiab cov khoom lag luam thiab kev thov. Kev yuav khoom ntau feem ntau muab cov nqi sib tw ntau dua.
