Kev sib tsoo log yog lub ntsiab sib tsoo 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 ntawm cov khoom sib tsoo, cov hlua khi thiab cov txheej txheem tsim tawm, cov yam ntxwv ntawm kev sib tsoo cov log kuj tseem sib txawv, uas muaj qhov cuam tshuam tseem ceeb ntawm kev sib tsoo zoo, kev tsim khoom thiab kev lag luam.
Txhawm rau txhawm rau txhim kho lub tshuab nqus dej ntawm kev sib tsoo lossis tiv thaiv cov khoom ntoo ntawm cov khoom ua kom tsis txhob tuaj yeem ua raws li cov hmoov txhuv nplej thaum lub sijhawm sib tsoo, cov khoom siv pabcuam tuaj yeem sib xyaw rau hauv cov hniav sib tsoo thaum lub sijhawm tsim cov txheej txheem, lossis cov khoom ntim tuaj yeem ntxiv los ntawm nias,, ntsw thiab lwm txoj kev tom qab kev tsim khoom. Piv txwv li, thaum sib tsoo stainless hlau, cryolite muaj lub ntsiab lus yaj ntawm 959 ° C, uas tuaj yeem yaj thiab thaj chaw ua haujlwm ntawm kev sib tsoo lub log kom tiv thaiv tau hlau nplaum. Lwm yam sau cov ntaub ntawv xws li hlau sulfide, polyvinyl chloride, boron thiab nyiaj tuaj yeem decompose cov tshuaj lom neeg nquag ua haujlwm hauv qab qhov txiav txim ntawm sib tsoo kub. Cov roj cua no lub zog tawm tsam nrog cov haujlwm ntawm qhov chaw ua haujlwm los tsim cov yeeb yaj kiab nyias kom tiv thaiv kev nplaum. Ntxiv rau, xws li graphite thiab boron nyiaj.
Qee lub sij hawm txheej polyvinylidene fluoride los yog molybdenum disulfide nyob rau saum npoo ntawm kev sib tsoo lub log hauv qab lub siab tuaj yeem tsim cov zaj duab xis nrog cov co co tsis tshua muaj sib txhuam ntawm qhov sib tiv tauj kom txhim kho lub xeev sib tsoo. Cov tshuaj no tuaj yeem raug suav tias yog cov roj nplua nyeem lossis lwm yam kev sib tsoo ntawm lub log muab tub.
