Cov txheej txheem hlau stamping tuaj yeem muab faib ua ob hom loj: txheej txheem sib cais thiab txheej txheem tsim.
Cov txheej txheem kev sib cais yog cais cov thwj cim los ntawm qhov khoob raws li cov kab contour uas tau hais tseg thaum lub sij hawm stamping, thaum ua kom ntseeg tau tias qhov zoo ntawm qhov sib cais ua tau raws li qee qhov yuav tsum tau ua. Cov txheej txheem tsim muaj xws li plastically deforming lub stamped dawb paug yam tsis muaj kev puas tsuaj rau nws, hloov nws mus rau hauv qhov xav tau cov duab tiav, thaum tseem ntsib qhov ntev ntev.
Raws li qhov kub stamping, muaj ob txoj hauv kev: txias stamping thiab kub stamping. Qhov no yog nyob ntawm cov khoom siv lub zog, plasticity, thickness,℃ntawm deformation, thiab cov cuab yeej muaj peev xwm, thaum tseem xav txog cov khoom qub thaum tshav kub kub kho lub xeev thiab cov kev pabcuam zaum kawg.
Hlau stamped qhov chaw yuav tsum tau tiv thaiv- kev kho corrosion thaum lub sij hawm tsim khoom kom zoo tiv thaiv corrosion thaum siv. Cov txheej txheem tseem ceeb suav nrog rau rau hauv qab no:
Asphalt xim txheej: Preheating lub stamped ib feem ua ntej painting txhim kho cov adhesion ntawm asphalt xim thiab ceev kom qhuav.
Cement mortar hauv ob sab phlu nrog cov txheej tshwj xeeb: Qhov no txhim kho qhov kev tiv thaiv corrosion ntawm lub stamped sab hauv hauv ob sab phlu.
Lub epoxy coal tar txheej rau hlau stamping qhov chaw yog ob- cov txheej txheem txheej nrog cov adhesion siab thiab qhov chaw du heev.
Epoxy ceramic linings, vim lawv cov txheej txheem tsim khoom thiab cov nqi siab, muaj qee yam kev txwv hauv daim ntawv thov. Txawm li cas los xij, lawv muaj qhov adhesion siab thiab ua kom tiav, ua rau lawv zoo heev los tiv thaiv -corrosion txheej rau stamping qhov chaw.
