Abrasives caadi ahaan loo isticmaalo in badan oo kala duwan oo la xidhiidha geedi warshadaha oo ay ku jiraan qaabeynta iyo dhameystir ah qaybaha ka qalab kala duwan sida qoryaha, dhalooyinka, la taaban karo, caag, dhagax, bir, birta, super-Alloys iyo biraha ferrous aan sameeyey, iyo in ka badan qalaad waxyaabaha sida alaab, indhaha iyo qaybaha electronic.
Taariikh ahaan, qalabka hadal haynta ayaa ugu horrayn ka soo jeeda macdanta dabiiciga ah sida Emery, ciid quartz iyo dheemman. Maanta, si kastaba ha ahaatee, warshadaha ee abrasives waa ku dhowaad oo gebi ahaanba ku tiirsan qalabka isku dardaro, taas oo ka fog dheeraad ah oo joogto ah ee Halabuurka iyo kharash-ool ah ka badan ka horreeyay dabiiciga ah ay yihiin. qalab dardaro guud ahaan waa ka badan kharash-ool ah sida ay u muuqdaan in ay noqon by-products ama durdurrada qashinka ah hababka in iyaga ay soo saaraan sida korontada dikhaw biraha. Iyadoo macdanta dabiiciga ah ayaa weli ku baahay, waxay u muuqdaan in loo isticmaalo codsiyada takhasus sare leh sida nadiifinayo iyo dhameystir wanaagsan ay sabab u tahay in ay qiime sare.
The saddex nooc hoose ee abrasives-soo-saarka waa la dahaarka leh, addoonsi iyo abrasives dabacsan. abrasives dahaarka leeyihiin xaashi, dhar ama taageero kale oo la mid ah. abrasives addoonsi ka mid ah shiidi giraangiraha iyo ulo. abrasives dabacsan waxaa loo isticmaalaa-engeeg iyo kuwa loogu talagalay, iyo waxyaabo kale, ka saarida ee rinjiga iyo miridhku iyo diyaarinta meelaha cusub. nooc kasta oo wax soo saarka sugi lahaayeen talagalay shuruudaha kala duwan marka la eego ka mid ah caddaymaha dusha ku dhameystaan, qaabka iyo cabbirka of qayb ka, hantida jirka (sida qalbi engegnaantooda aawadeed, xoog iyo heerkulka xadka) iyo shuruudaha faahfaahsan shiididdu gaar ah ama habka la dhammeeyo. Sifooyinka wax ka sugi lahaayeen (tusaale ahaan, cabbirka, qaabka, xoog, cufnaanta iyo qalbi engegnaantooda) inay khatar ku yihiin adeegsigeeda gaar ah, sida ay yihiin guryaha ee wax furta (tusaale ahaan, cusbi, oo hallawda ama biraha) iyo shahaado of porosity.
Codsiyada abrasives dabacsan u dhaxayn nadiifinta dusha iyo peening, u diyaarinta dib u soo celinta iyo dusha qalabka loogu talagalay blaastiigga difaaca ah. A suuqa labaad ee ugu weyn ee abrasives dabacsan yahay nadiifinta qaraxa oo ranji ah buundooyinka iyo buundooyinka. Waxa intaa dheer in labadan suuqyada, waxaa jira boqolaal codsiyada warshadaha halkaas oo abrasives dabacsan waxaa loo isticmaalaa diyaarinta dusha, nadiifinta dusha iyo sida qayb ka mid ah alaabooyinka kale ee la dhammeeyayna.
nadiifinta qaraxa sugi lahaayeen koobay habab kala duwan oo ay ku jiraan isticmaalka dhawr nooc oo ah warbaahinta laga gano by biyo ama hawada. The warbaahinta abrasives wuu isbedelaa, ka godadka bariiska iyo qolofka walnut in slags kala duwan, Garnet iyo shot steel. Qarax caadi ah macdanta nadaafadda waxaa ka mid ah staurolite, olivine, hematite specular iyo Garnet. warbaahinta Man-dhigay loo isticmaalo nadiifinta Qarax ka mid caag ah, macdanta dahaarka leh, dhalo dib loo warshadeeyey, shot steel, slag dhuxusha, slag copper iyo slag nickel.
In ka badan 50 sano, silica ayaa inta badan la isticmaalo sugi lahaayeen nadiifinta qaraxa sugi lahaayeen, Sayidka Cukuse ee sandblasting ereyga, sida ay tahay dhaqaale iyo fududahay in la isticmaalo.
