Tso lus
Dej -} Cov khoom lag luam txaus ntshai, tseem hu ua dej sandpaper, yog hom ntawm coated abrasive tshwj xeeb tsim los ntawm ntub kev sib tsoo txheej txheem. Nws siv cov dej - tiv taus daim ntawv yas lossis cov ntawv sau ua ke kom haum nrog cov nplaum nplaum kom tsim cov ntawv lossis yob qauv qauv. Nws cov peev xwm tseem ceeb xws li cov dej tsis kam, tso cai rau nws xau dej ntev uas tsis muaj cov abrasive nplej dualling; Lub sij hawm ntub kev sib tsoo, cov khib nyiab yog nqa tawm los ntawm dej ntws, muaj txiaj ntsig kev tiv thaiv txhaws thiab txuas ntxiv nws lifespan; Nws npog ntau qhov sib thooj los ntawm P60 rau P3000, deb tshaj qhov tsis yooj yim qhaub cij, thiab tshwj xeeb yog tsim nyog rau siab {precision polishing; Kev sib tsoo ntub txo cov plua plav paug, txhim kho kev ua haujlwm, thiab txo qis kev pheej hmoo ntawm kev tawg. Nws yog dav siv hauv Automotive, Woodworking, Hlau ua haujlwm, thiab lwm yam khoom siv, thiab txhawb ob qho kev sib tsoo, thiab cov khoom sib tsoo kom qhuav thiab raug nqi- ua hauj lwm zoo.
I. Cov Ntsiab Lus thiab Cov Qauv Tseem Ceeb
1.1 Cov ntsiab lus tseem ceeb
Waterproof sandpaper yog ib co coated abrasive tsim rau ntub kev sib tsoo. Qhov tseem ceeb, nws yog tsim los ntawm kev sib txuas siab siab- wardness Abrasive nrog cov khoom siv tshwj xeeb, cov cuab yeej sib tsoo nrog cov cuab yeej sib tsoo. Raws li JB / T 7499-2006 txuj ci, waterproof bandpaper yuav tsum ua kom muaj kev sib tsoo, thiab lub zog ntub, thiab lub zog ntub dej yuav tsum mus txog 75% ntawm nws lub xeev qhuav.
