Abrasive nplej

Paj yeeb Fused alumina (pfa), kuj tau npe hu ua pined txhuas oxide, yog ua raws li cov txheej txheem zoo sib xws raws li cov neeg dawb feded alumina. Tsuas yog ntxiv qee qhov nyiaj ntawm chromium oxide thaum lub smelting nyob rau hauv thiaj li yuav nce zuj zus ntawm cov ntaub ntawv. Nws lub hardness yog tib yam li dawb feded alumina tab sis nws cov tawv yog siab dua cov dawb aluminium.

Iav hlaws

Fiberglass thim rov qab

Fiberglass disc yog tuag-txiav-txiav los ntawm cov phuam fiberglass uas yog coated nrog phenolic thiab epoxy cob. Nrog cov yam ntxwv zoo xws li kev ua tau zoo nrog abrasives, kev ceev ntawm cov cua sov ua haujlwm, kev kub ceev cov khoom siv hluav taws xob zoo tshaj plaws rau cov khoom siv sib txawv ntawm cov log txiav thiab sib tsoo log.
