1. Txheeb xyuas lub zog txuas: Sib tsoo lub nraub qaum ntawm lub cuab yeej tig nrog ntsuab silicon carbide sib tsoo lub log, thiab txheeb xyuas qhov tuab ntawm txheej txheej txheej. Cov tuab yuav tsum tau tsawg dua 0.15 hli.
2. Txheeb xyuas txoj haujlwm ntawm cov hniav hauv qhov riam: yog tias tus nplais pom tau tias cov hniav tsis zoo, yuav tsum rov siv vuam dua.
3. Txheeb xyuas lub zog txuas: ntaus cov hniav nrog rauj ntoo lossis rauj tooj liab liab nrog lub zog nruab nrab, thiab cov hniav tsis poob los ntawm lub qhov yog suav tias tsim nyog.
4. Txheeb xyuas qhov dav ntawm cov hniav: Yog tias muaj qhov nyob ntawm cov hniav ntawm tus slitter, nws txhais tau tias cov hniav kub dhau thiab deformed, thiab cov hniav tshiab yuav tsum tau hlawv thiab rov txuas dua.
5. Txheeb xyuas qhov tawg: Tom qab cov hniav raug ntxuav los ntawm kerosene, yog tias cov hniav tawg. Kerosene nkag mus rau hauv cov kab nrib pleb thiab cov kab dub tshwm, uas tuaj yeem pom nrog qhov muag liab qab.
