Flap discs yog ntau yam kev sib tsoo thiab cov cuab yeej xuab zeb uas pom lawv daim ntawv thov thoob plaws ntau yam kev lag luam. Cov ntaub ntawv raw siv los ua cov flap discs txawv ntawm cov nplej abrasive, cov khoom siv rov qab, thiab cov nplaum siv hauv lawv cov kev tsim kho. Nov yog qee qhov sib txawv ntawm cov khoom siv raw siv rau flap discs:
1. Abrasive grain: Abrasive grain siv nyob rau hauv flap discs yuav ua los ntawm txhuas oxide, zirconia alumina, ceramic, los yog pob zeb diamond. Aluminium oxide yog cov feem ntau abrasive grain thiab yog haum rau feem ntau cov hom phiaj sib tsoo thiab sanding daim ntaub ntawv. Zirconia alumina yog cov khoom siv ruaj khov uas ua haujlwm zoo ntawm cov hlau tawv xws li stainless hlau thiab titanium. Ceramic yog qhov nyuaj tshaj plaws abrasive thiab yog qhov zoo tshaj plaws rau kev siv hnyav. Pob zeb diamond yog qhov nyuaj tshaj plaws abrasive thiab yog siv rau kev sib tsoo thiab polishing cov ntaub ntawv nyuaj.
2. Cov khoom siv thaub qab: Flap discs tuaj yeem muaj cov ntaub los yog cov khoom siv fiber ntau. Cov ntaub ntawv rov qab yog hloov tau yooj yim dua thiab ua tau zoo dua rau contours thiab nkhaus. Lawv haum rau lub teeb rau nruab nrab sib tsoo thiab ua tiav daim ntawv thov. Fiber backings yog nruj thiab ruaj khov dua, ua rau lawv haum rau hnyav-duty sib tsoo thiab txiav daim ntaub ntawv.
3. Adhesive: Cov nplaum uas siv rau hauv flap discs tuav cov nplej abrasive rau cov khoom siv rov qab. Resin yog cov nplaum uas siv ntau tshaj plaws thiab tsim nyog rau feem ntau kev sib tsoo thiab kev siv xuab zeb. Epoxy yog cov nplaum nplaum uas muaj zog dua li cov resin thiab siv rau cov ntawv siv hnyav. Super kua nplaum yog siv rau ultra-fine sanding thiab polishing daim ntaub ntawv.
Hauv kev xaus, kev xaiv ntawm cov khoom siv raw siv rau flap discs nyob ntawm daim ntawv thov tshwj xeeb. Cov khoom sib txawv abrasive, cov ntaub ntawv thaub qab, thiab cov nplaum muaj cov yam ntxwv sib txawv, ua rau qee qhov nrov plig plawg disc zoo dua rau qee yam kev sib tsoo thiab xuab zeb ntau dua li lwm tus. Txawm hais tias siv cov khoom siv, flap discs yog cov cuab yeej tseem ceeb rau txhua tus neeg uas xav tau tshem tawm cov khoom los ntawm qhov chaw los yog ua kom cov khoom tiav.
