Abrasive

Muaj ntau yam ntawmabrasives, los ntawm softer tsev detergents thiab lub pov haum abrasives mus rau lub hardest khoom, pob zeb diamond. NY TWO's abrasives yog cov ntse, cov ntaub ntawv nyuaj siv los zom cov khoom softer.

Muaj ob hom abrasives: natural abrasives thiab artificial abrasives. Raws li qhov nyuaj ntawm kev faib tawm ntawm superhard abrasives thiab zoo tib yam abrasives ob pawg. Abrasives yog cov ntaub ntawv tseem ceeb rau kev tsim khoom ntawm txhua yam khoom zoo. Ntau lub ntuj abrasives tau hloov los ntawm cov khoom siv dag zog. Ntxiv nrog rau pob zeb diamond, kev ua haujlwm ntawm ntuj abrasives tsis ruaj khov, tab sis nws tseem muaj nws cov nqi siv.

Pob zeb diamond yog qhov nyuaj tshaj plaws abrasive, ua rau hauv South Africa, suav txog 95% ntawm lub ntiaj teb tag nrho cov khoom, tus so yog Brazil, Australia, Guyana thiab Venezuela thiab lwm qhov chaw. Muaj pob zeb diamond los ntawm grey dawb mus rau dub, tom qab kev sib tsoo tuaj yeem ua rau sib tsoo log, siv xuab zeb, polishing log thiab sib tsoo hmoov.

Txij li thaum xyoo 1970, ntau cov khoom siv dag zog tau tsim, qhov tseem ceeb tshaj plaws yog silicon carbide thiab alumina. Silicon carbide, feem ntau hu ua carborundum, yog npaj los ntawm kev sib xyaw cov xuab zeb ntshiab si nrog coke thiab ntxiv me me ntawm cov ntoo chips rau hauv lub cub hluav taws xob thiab ci ntawm 2,200 ~ 2,480 degree rau li 36 teev.

Alumina, feem ntau hu ua corundum, feem ntau yog siv rau hauv kev lag luam kom yaj bauxite los ntawm hluav taws xob arc rauv cua sov, dawb thiab pob tshab raws li abrasive rau tshav kub-rhiab hlau, thiab dub rau ua castings thiab hlau.

Lub hardness ntawm boron carbide yog siab dua li ntawm silicon carbide, uas tsis haum rau kev sib tsoo log, thiab yuav siv tau es tsis txhob kim pob zeb diamond thaum polishing cov ntaub ntawv nyuaj.

NY TWO xim av corundum yog tsim los ntawm cov qib siab zoo abrasive bauxite thiab cov ntaub ntawv pabcuam los ntawm kev ua kom zoo ntawm qhov kub siab tshaj 2250 degree hauv hluav taws xob arc rauv. Nws muaj qhov zoo ntawm tus kheej ntse thiab muaj zog sib tsoo quab yuam. Kev siv lub ntsiab ntawm cov xim av corundum yog: tuaj yeem ua los ntawm ceramic sib tsoo log, cob sib tsoo log, sib tsoo lub taub hau, sib tsoo thaiv, ntawv xuab zeb, siv xuab zeb, ntaub emery thiab polishing wax,abrasivetus neeg sawv cev, sib tsoo muab tshuaj txhuam, pleev xim thiab lwm yam.
