Silica-Free Abrasives rau Blast Cleaning
Abrasives feem ntau yog siv rau ntau yam kev lag luam nrog rau kev tsim thiab ua tiav ntawm cov khoom tsim los ntawm ntau yam ntaub ntawv xws li ntoo, iav, pob zeb, yas, pob zeb, hlau, hlau, super-alloys thiab non-ferrous hlau, thiab ntau yam kab txawv. cov khoom xws li jewels, optical thiab electronics Cheebtsam.
Keeb kwm, cov ntaub ntawv abrasive feem ntau yog muab los ntawm tej yam ntuj tso xws li emery, quartz xuab zeb thiab pob zeb diamond. Niaj hnub no, txawm li cas los xij, kev lag luam abrasives yuav luag tag nrho nyob ntawm cov khoom siv hluavtaws, uas muaj ntau yam zoo sib xws hauv kev sib xyaw thiab siv tau zoo dua li lawv cov neeg ua ntej. Cov khoom siv hluavtaws feem ntau yuav raug nqi ntau dua vim lawv nyiam los ntawm cov khoom lossis cov dej khib nyiab ntawm cov txheej txheem uas tsim lawv xws li kev tsim hluav taws xob thiab cov hlau smelting. Txawm hais tias tej yam ntuj tso minerals tseem muaj nyob, lawv nyiam siv rau cov kev siv tshwj xeeb xws li polishing thiab ua kom zoo vim lawv cov nqi siab dua.
Peb lub hom phiaj tseem ceeb ntawm cov khoom abrasives yog coated, bonded thiab xoob abrasives. Coated abrasives muaj ib daim ntawv, ntaub los yog lwm yam zoo sib xws. Bonded abrasives muaj xws li sib tsoo log thiab sticks. Loose abrasives yog siv rau blasting thiab tumble rau, ntawm lwm yam, tshem tawm cov xim thiab xeb thiab kev npaj ntawm qhov chaw tshiab. Txhua yam ntawm cov khoom abrasive caters rau cov kev xav tau sib txawv nyob rau hauv cov nqe lus ntawm qhov chaw tiav specifications, cov duab thiab qhov loj ntawm cov khoom, nws lub cev (xws li hardness, lub zog thiab kub txwv) thiab cov ncauj lus kom ntxaws yuav tsum tau ntawm cov kev sib tsoo los yog xov. Cov yam ntxwv ntawm cov khoom siv abrasive (piv txwv li, lub zog, ntom ntom, rov ua dua, cov vitreous lossis hlau) thiab degrosity.
Daim ntawv thov rau xoob abrasives muaj xws li los ntawm kev tu thiab peening, mus rau lub restoration thiab nto npaj cov ntaub ntawv rau kev tiv thaiv txheej. Ib qho kev lag luam loj thib ob rau xoob abrasives yog kev ntxuav thiab rov ua dua tshiab ntawm cov choj thiab hla hla. Ntxiv rau ob lub lag luam no, muaj ntau pua daim ntawv thov kev lag luam uas xoob abrasives yog siv rau kev npaj nto, ntxuav thiab ua ib feem ntawm lwm cov khoom tiav.
Abrasive moj tej tawg tu encompasses ntau txoj kev uas muaj xws li kev siv ntau hom xov xwm propelled los ntawm dej los yog huab cua. Cov xov xwm abrasives sib txawv, los ntawm cov nplej hulls thiab walnut plhaub mus rau ntau yam slags, garnet thiab hlau txhaj tshuaj. Cov tshuaj tua kab mob xws li staurolite, olivine, specular hematite thiab garnet. Cov neeg tsim tawm xov xwm siv rau kev ntxuav moj tej tawg muaj xws li yas, coated minerals, recycled iav, steel txhaj, thee slag, tooj liab slag thiab npib tsib xee slag.
Rau ntau tshaj 50 xyoo, silica tau yog cov feem ntau siv abrasive rau abrasive moj tej tawg tu, yog li lub coining ntawm lub sij hawm sandblasting, raws li nws yog yig thiab yooj yim rau siv.
