Dab tsi yog pawg ntawm kev siv thev naus laus zis rau cov hlau stamped qhov chaw?

Cov txheej txheem txheej txheem ntawm cov hlau stamped qhov chaw tuaj yeem muab faib ua ob pawg: txheej txheem sib cais thiab txheej txheem tsim.
Cov txheej txheem sib cais muaj kev sib cais ntawm cov khoom sib dhos thiab qhov khoob ntawm ib leeg los ntawm ib qho ntawm cov kab contour thaum lub sij hawm stamping txheej txheem tib lub sij hawm, qhov zoo ntawm cov khoom sib cais ntawm cov khoom stamped yuav tsum tau ua raws li qee qhov kev cai, cov txheej txheem tsim muaj ua rau cov yas. deformation ntawm stamping blanks yam tsis muaj kev puas tsuaj thiab hloov lawv mus rau hauv cov khoom uas yuav tsum tau ua tiav, thiab tib lub sij hawm lawv yuav tsum tau ua raws li qhov yuav tsum tau ntawm dimensional tolerances thiab lwm yam.
Raws li qhov kub thiab txias thaum lub sij hawm stamping, ob txoj kev yog qhov txawv: txias stamping thiab kub stamping. Qhov no nyob ntawm lub zog, ductility, thickness, degree ntawm deformation thiab cov cuab yeej muaj peev xwm ntawm cov khoom, nrog rau kev kho cua sov thawj zaug thiab qhov kawg ntawm cov khoom siv.
Hlau stamping qhov chaw yuav tsum tau kho nrog kev tiv thaiv corrosion thaum lub sij hawm tsim khoom kom tsis txhob muaj corrosion thaum siv cov txheej txheem tseem ceeb yog raws li hauv qab no:
1. Txheej nrog asphalt xim, preheating qhov chaw stamped ua ntej pleev xim tuaj yeem txhim kho qhov adhesion ntawm asphalt xim thiab ua kom qhuav.
2. Ntxiv cov txheej tshwj xeeb rau cov cement mortar hauv ob sab phlu tuaj yeem txhim kho corrosion kuj ntawm cov khoom stamping hauv ob sab phlu.
3. Epoxy carbon pitch txheej rau hlau stamping qhov chaw yog ob txheej txheej uas muaj zog adhesion thiab du heev.
4. Vim yog cov txheej txheem tsim khoom thiab tus nqi siab, epoxy ceramic hauv ob sab phlu muaj qee qhov kev txwv hauv kev siv, muaj adhesion siab thiab smoothness, thiab yog ib qho zoo heev los tiv thaiv corrosion txheej rau stamped qhov chaw.
