Hlau Grit
Muaj Hardness:
GP: HRC46-50
Cov khoom tsim tshiab tshiab nrog angular, cov grit yog maj mam sib npaug ntawm kev siv thiab nws tshwj xeeb tshaj yog haum rau oxide daim tawv nqaij ua ntej kho.
GL: HRC56-60
Nyuaj tshaj GP steel grit, kuj poob nws cov npoo ntse thaum lub sij hawm txhaj tshuaj basting thiab tshwj xeeb tshaj yog haum rau daim ntaub ntawv npaj nto.
GH: HRC63-65
High hardness, ntse npoo nyob twj ywm thaum lub sij hawm ua hauj lwm, feem ntau yog siv rau compressed cua tua blasting khoom.
Lub zog ntau lawm:
TAA txais Arc Rauv Smelting thiab Ob Chav Quenching thev naus laus zis, uas lav nws cov hlau abrasives 'tshuaj lom neeg muaj pes tsawg leeg thiab lub zog siab, siab tawv, ua haujlwm ntev.
