Kev sib tsoo yog qhov tseem ceeb tshaj plaws nyob rau hauv kev sib tsoo. Kev sib tsoo log yog lub cev ntxeem tau, uas tau ua los ntawm kev ntxiv phau ntawv rau lub abrasive, nias lub khoob, kom qhuav thiab ci. Vim tias qhov sib txawv hauv kev ua kom tsis muaj zog, khi thiab tsim cov txheej txheem, cov yam ntxwv ntawm kev sib tsoo cov log kuj tseem sib txawv, uas muaj kev cuam tshuam zoo ntawm kev sib tsoo, kev tsim khoom thiab kev lag luam. Cov yam ntxwv ntawm kev sib tsoo log yog tsuas yog txiav txim siab los ntawm cov yam ntxwv xws li abrasive, particle loj, binder, tawv, lub koom haum, cov duab thiab loj.
Nta:
Kev sib tsoo log yog ib yam ntawm cov abrasive uas muaj ntau yam siv. Thaum siv, nws tig ntawm kev kub ceev thiab tuaj yeem ntxhib, ib nrab tiav, zoo nkauj zom, lub qhov, thiab khi lub voj voog sab hauv, sab hauv lub voj voos, dav hlau thiab ntau yam kis ntawm cov hlau lossis cov hlau tsis ua haujlwm.
Ntau yam:
Raws li cov abrasives siv, nws muaj peev xwm muab faib ua cov tsiaj ua kom zoo (corundum, silicon carbide, thiab lwm yam). Kev sib tsoo log, ntuj abrasive, super-nyuaj abrasive thiab (pob zeb diamond, cubic boron nitride sib tsoo lub log, thiab lwm yam) sib tsoo lub log. Raws li cov duab, nws tuaj yeem muab faib ua tiaj tus sib tsoo lub log, sib tsoo lub log sib tsoo, lub tog raj kheej sib tsoo, lub khob sib tsoo lub log, thiab lub tais sib tsoo lub log. Raws li cov khoom sib txawv sib txawv, nws tuaj yeem muab faib ua cov sib tsoo log, log sib tsoo log, roj hmab sib tsoo cov log, hlau sib tsoo lub log thiab lwm yam. Cov yam ntxwv ntawm lub sib tsoo log feem ntau muaj xws li abrasive, viscosity, hardness, bond bond, shape, loj thiab lwm yam.
Ntxuav tau:
Hauv cov txheej txheem ntau lawm, txoj siv sia yog txhuam nrog cov hniav sib tsoo. Feem ntau, kev sib tsoo log tsis siv neeg thiab ntxuav tawm tom qab 5-7 hnub ua haujlwm.
