Cov Khoom Siv Walnut Fiber Ntau Ruaj Khoov Grit
Kev piav qhia txog khoom
Cov xuab zeb Walnut plhaub yog cov khoom ua los ntawm cov plhaub Walnut uas raug zom lossis tsoo. Thaum siv ua cov khoom siv tua hluav taws, cov xuab zeb Walnut plhaub yog cov khoom siv ruaj khov heev, muaj lub kaum ntse ntse thiab ntau lub ntsej muag, tab sis suav tias yog 'cov khoom siv mos mos'. Cov xuab zeb Walnut plhaub tua hluav taws yog ib qho hloov pauv zoo heev rau xuab zeb (silica dawb) kom tsis txhob muaj teeb meem kev noj qab haus huv ntawm kev ua pa.
Kev ntxuav los ntawm kev siv lub plhaub ntoo walnut blasting yog qhov zoo tshaj plaws thaum qhov chaw ntawm lub substrate hauv qab nws cov xim pleev xim, av, roj, nplai, carbon, thiab lwm yam yuav tsum tsis hloov pauv lossis tsis muaj kev puas tsuaj. Cov xuab zeb ntawm lub plhaub ntoo walnut tuaj yeem siv ua cov khoom sib xyaw mos mos hauv kev tshem tawm cov khoom txawv teb chaws lossis cov txheej txheem ntawm cov chaw yam tsis muaj kev khawb, khawb lossis ua rau cov chaw ntxuav puas.
Thaum siv nrog cov khoom siv tua hluav taws xob zoo, cov ntawv thov tua hluav taws xob feem ntau suav nrog kev tshem tawm cov vaj huam sib luag ntawm lub tsheb thiab lub tsheb thauj khoom, ntxuav cov pwm mos, txhuam hniav nyiaj hniav kub, cov khoom siv thiab cov cav hluav taws xob ua ntej rov ua dua, tshem cov yas thiab txhuam lub moos. Thaum siv ua cov khoom siv tua hluav taws xob, cov xuab zeb ntawm lub plhaub txiv ntseej tshem tawm cov xim, flashing, burrs thiab lwm yam qhov tsis zoo hauv cov yas thiab roj hmab molding, txhuas thiab zinc die-casting thiab kev lag luam hluav taws xob. Lub plhaub txiv ntseej tuaj yeem hloov cov xuab zeb hauv kev tshem tawm xim, tshem tawm graffiti thiab kev ntxuav dav dav hauv kev kho dua tshiab ntawm cov tsev, choj thiab cov duab puab sab nraum zoov. Lub plhaub txiv ntseej kuj tseem siv los ntxuav cov cav dav hlau thiab cov turbines pa dej.
