JIS Standard Dawb Fused Alumina rau Coated Cloth Abrasives Dawb Fused Alumina Wfa
Dawb Fused Alumina Taw Qhia
Dawb fused alumina (WFA)yog ib tug hluavtaws abrasive khoom uas ua los ntawm fusing high-purityaluminanyob rau hauv ib qho hluav taws xob arc rauv ntawm qhov kub thiab txias.Nws muaj cov qauv siv lead ua feem ntau yog corundum (Al2O3) thiab paub txog nwsTshwj xeeb hardness, lub zog, thiab siab purity.Dawb fused alumina muaj nyob rau hauv ntau hom, suav nroggrits, xuab zeb, thiab hmoov, thiab yog siv nyob rau hauv ntau yam kev siv:Sib tsoo thiab Polishing, Kev Npaj Nto, Refractories, Precision Casting, Abrasive Blasting, Superabrasives, Ceramics thiab Vuas, thiab lwm yam.

-
Sib tsoo thiab polishing: abrasive log, siv, thiab discs rau precision sib tsoo ntawm cov hlau, ceramics, thiab composites.
-
Kev Npaj Nto: tshem tawm nplai, xeb, xim, thiab lwm yam kab mob ntawm cov hlau substrates
-
Refractories: firebricks, refractory castables, thiab lwm yam zoo li tus los yog unshaped refractory khoom
-
Precision Casting: qhov tseeb qhov tseeb, qhov chaw du, thiab txhim kho casting zoo.
-
Abrasive Blasting: tshem tawm xeb, xim, nplai, thiab lwm yam kab mob los ntawm qhov chaw yam tsis muaj kev puas tsuaj.
-
Superabrasives: high-speed steels, cuab yeej steels, thiab ceramics
-
Ceramics thiab Vuas
