Kev sib piv ntawm Frosting txheej txheem thiab Sandblasting txheej txheem
Xuab zeb blasting yog ib qho haujlwm uas siv cov cua compressed ua lub zog los thawb cov abrasives rau saum npoo ntawm lub workpiece rau kev kho mob. Qhov no yog qhov hu ua xuab zeb blasting, uas yog qhov peb feem ntau hu ua txhaj tshuaj blasting. Vim hais tias xuab zeb yog cov abrasive uas yuav siv tau nyob rau hauv thaum ntxov hnub ntawm kev txhaj tshuaj peening, txhaj tshuaj peening yog ces thiab tau ntev txij li thaum lub npe hu ua grit blasting. Xuab zeb blasting tuaj yeem ua rau saum npoo yuav tsum tau muab ntxuav kom tau qhov kev huv huv thiab kev ntxhib los mos, thiab txhim kho qhov adhesion ntawm txheej ntawm lub hauv paus nto. Txawm hais tias cov txheej txheej zoo npaum li cas, nws tsis tuaj yeem ua raws li qhov chaw ntawm lub workpiece yam tsis muaj kev kho deg ntev. Lub hom phiaj ntawm kev kho deg yog los ntxuav qhov saum npoo thiab tsim qhov roughness yuav tsum tau "xauv" txheej rau saum npoo. Tom qab xuab zeb blasting, nto ntawm lub workpiece yog coated nrog ib tug muaj txheej txheej nrog kev ua tau zoo, thiab cov kev pab cuam lub neej ntawm lub txheej yog 3.5 lub sij hawm ntev tshaj li qhov zoo tib yam txheej rau saum npoo kho los ntawm lwm txoj kev. Lwm qhov zoo ntawm sandblasting (steev peening) yog qhov roughness ntawm qhov chaw tuaj yeem raug txiav txim siab raws li qhov yuav tsum tau ua thiab tuaj yeem ua tiav thaum lub sijhawm ntxuav.
Frosting yog, piv txwv li, cov txheej txheem ntawm smoothing thiab matting cosmetic iav fwj, thiab lub teeb hits saum npoo los tsim ib tug diffuse reflection. Hauv cov tshuaj frosting, iav yog hauv av mechanically los yog manually nrog corundum, silica xuab zeb, pomegranate hmoov, thiab lwm yam abrasives los tsim ib tug uniform thiab ntxhib nto, los yog iav thiab lwm yam khoom yuav kho nrog ib tug hydrofluoric acid tov los tsim frosted iav.
Ob qho tib si frosting thiab sandblasting yog siv los npog cov iav saum npoo, yog li lub teeb yuav tsim ib qho kev sib cais zoo sib xws tom qab dhau los ntawm lub teeb. Nws yog qhov nyuaj rau cov neeg siv nruab nrab kom paub qhov txawv ntawm ob lub thev naus laus zis. Yuav ua li cas txhua yam ntawm cov thev naus laus zis no tau tsim thiab yuav txheeb xyuas lawv li cas tau piav qhia hauv qab no.
1. txheej txheem txhuam
Frosting yog hais txog immersing iav nyob rau hauv ib tug npaj acidic kua (los yog siv ib tug acidic muab tshuaj txhuam) kom corrode iav nto nrog ib tug muaj zog acid, thiab cov ammonia hydrogen fluoride nyob rau hauv cov kua qaub muaj zog ua rau cov iav saum npoo ntawm crystals. Yog li ntawd, yog tias cov txheej txheem frosting ua tiav zoo, qhov saum npoo ntawm cov iav frosted yog du heev, thiab cov muaju tsim los ntawm kev tawg ua rau cov nyhuv hazy. Yog hais tias qhov saum npoo yog qhov ntxhib, qhov no qhia tau hais tias cov kua qaub tawm tsam lub khob tsis zoo, lossis qee qhov ntawm lawv tseem tsis muaj cov muaju. Cov txheej txheem yog tus cwj pwm los ntawm cov tsos ntawm ci ntsa iab crystals ntawm cov iav tsim nyob rau hauv cov xwm txheej tseem ceeb. Qhov laj thawj tseem ceeb yog tias ammonium hydrogen fluoride tau mus txog qhov chaw uas nws yuav luag tag. Yuav kom ua tiav lub xeev no, ntau lub tuam txhab tau ua ntau yam kev sim thiab kev tshawb fawb, tab sis tsis muaj leej twg tuaj yeem kov yeej qhov teeb meem no.
2. Xuab zeb blasting tshuab
Nws tsoo lub iav nto nrog cov xuab zeb hais tawm los ntawm rab phom txau ntawm kev kub ceev, ua kom zoo zoo concave-convex nto, thiaj li ua tiav cov nyhuv ntawm lub teeb tawg, thiab tsim kom muaj kev ntxhov siab thaum lub teeb hla. Qhov saum npoo ntawm cov khoom iav uas ua los ntawm cov txheej txheem sandblasting zoo li ntxhib. Txij li cov iav nto puas lawm, nws zoo li iav dawb ntawm lub teeb rhiab heev ntawm cov iav qub.
Ob txheej txheem sib txawv kiag li. Frosted iav yog kim dua sandblasted iav, thiab cov nyhuv feem ntau yog nyob ntawm cov kev xav tau ntawm cov neeg siv. Qee cov tsom iav tshwj xeeb tsis haum rau frosting. Los ntawm qhov pom ntawm kev ua siab zoo, frosting yuav tsum tau xaiv. Cov txheej txheem sandblasting tuaj yeem ua tiav nyob rau hauv lub Hoobkas dav, tab sis cov txheej txheem frosting tsis yooj yim ua kom zoo.
