Sandblasting yog kev ua haujlwm uas siv huab cua compressed raws li lub zog kom thawb cov abrasives mus rau saum npoo ntawm workpiece rau kev ua. Qhov no yog qhov thiaj li hu ua sandblasting, uas yog dab tsi peb feem ntau hu txhaj tshuaj blasting. Vim hais tias thaum ntxov hnub ntawm kev txhaj tshuaj blasting, xuab zeb tsuas yog cov abrasive uas tuaj yeem siv, tawg tawg tau hu ua cov xuab zeb blasting nyob rau lub sijhawm ntawd thiab tau ntev tom qab ntawd. Sandblasting tuaj yeem ua rau lub saum npoo yuav tsum tau ntxuav kom tau txais kev huv thiab qee yam roughness, thiab txhim kho cov nplaum ntawm cov txheej txheem ntawm lub hauv paus nto. Txawm li cas los tau zoo npaum li cas cov txheej yog, nws tsis tuaj yeem txuas mus rau saum npoo ntawm workpiece yam tsis muaj kev kho kom ntev ntev. Lub hom phiaj ntawm kev tshwm sim saum npoo av yog los ntxuav cov nplaim thiab tsim cov roughness yuav tsum tau "xauv" cov txheej txheej. Tom qab saum npoo ntawm sandblasted workpiece yog coated nrog cov txheej txheem kev lag luam zoo, lub neej ntev dua li cov txheej txheem zoo tib yam ntawm lwm txoj kev kho. Lwm qhov zoo ntawm Sandblasting (txhaj tshuaj tiv thaiv blasting) yog tias lub ntsej muag roughness tuaj yeem ua tiav raws li cov kev xav tau thiab tuaj yeem ua tiav thaum lub sijhawm ntxuav.
Teasing yog, piv txwv li, tus txheej txheem uas aCov Khaub Ncaws Hnav Kom Huvua kom du thiab ua matte. Lub teeb irradiates saum npoo los ua daim ntawv diffuse. Hauv Tshuaj Txhuam Ua Ntej, iav yog cov hlauically hauv av nrog Emery, lossis lwm yam dej tsaws ntxhib, thiab lwm yam khoom muaj kuab, thiab lwm yam khoom siv tau los ua cov kua roj dolf.
Ob qho tib si ua kom tawg thiab sandblasting yog siv los npog cov iav saum npoo, kom lub teeb yuav diffuse sib txawv tom qab dhau los ntawm cov teeb meem. Nws yog qhov nyuaj rau cov neeg siv dog dig kom paub qhov txawv ntawm ob lub thev naus laus zis. Cov hauv qab no qhia txog kev tsim qauv ntawm ob lub thev naus laus zis thiab yuav ua li cas los txheeb xyuas lawv.
1. Cov txheej txheem Frosting
Frosting yog hais txog impersing lub khob nyob rau hauv ib tug npaj kua qaub ua kua (lossis thov cov kua qaub ua kua rau cov iav acid ua rau cov khoom siv acid ua rau cov muaju. Yog li ntawd, yog tias cov txheej txheem teas ua tau zoo, qhov saum npoo ntawm Frosted iav yog heev du, thiab cov muaju tawg ua rau cov nyhuv zoo heev. Yog tias saum npoo yog ntxhib, qhov no qhia tau tias cov kua qaub yog loj hlob ntawm iav, lossis qee qhov ntawm lawv tseem tsis muaj muaju. Cov yam ntxwv ntawm cov txheej txheem no yog cov tsos ntawm cov iav ci ci ntawm iav nto tsim nyob rau hauv cov xwm txheej tseem ceeb. Lub ntsiab yog vim li cas yog cov tshuaj fluoride ammonia yuav luag tau noj. Txhawm rau kom ua tiav lub xeev no, ntau lub tuam txhab tau tsim ntau yam thiab kev tshawb fawb, tab sis tsis tau kov yeej txoj kev nyuaj no.
2Cov. Sandblasting Tshuab
Nws siv cov xuab zeb cais tawm ntawm rab phom txau ntawm cov kev kub ceev, yog li ua tiav cov nyhuv ntawm cov khoom tawg, thiab tsim cov kev xav zoo li thaum lub teeb hla dhau. Qhov saum npoo ntawm cov khoom lag luam uas tsim los ntawm cov txheej txheem xuab zeb yog ntxhib. Vim tias cov nplaim hluav taws tau puas, nws zoo li iav dawb nyob rau hauv cov nqe lus ntawm cov duab ntawm cov thawj pob tshab iav.
Ob txoj txheej txheem yog txawv kiag li. Frosted iav yog kim dua li cov iav sandblasted, thiab cov nyhuv feem ntau yog nyob ntawm cov kev xav tau ntawm cov neeg siv. Qee cov iav tshwj xeeb tsis haum rau kev nkag. Kev txiav txim los ntawm cov chaw ua haujlwm tsis zoo, matte yuav tsum tau xaiv. Txheej txheem sandblasting tuaj yeem ua tau nyob rau hauv cov txheej txheem dav dav, tab sis cov txheej txheem xuab zeb tsis yooj yim ua tau zoo.
