- ** Kev sib xyaw ua ke: ** Lubricants yuav tsum sib haum nrog ob qho tib si cov khoom siv yeeb nkab thiab lwm yam ntaub ntawv uas lawv tau ntsib nrog thaum lub sij hawm installation, xws li av los yog lwm yam kav dej.
- **Environmental Impact:** Kev txiav txim siab ntawm ib puag ncig yam xws li biodegradability thiab toxicity yog ib qho tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv cov ecosystems rhiab heev los yog cov cheeb tsam nrog nruj ib puag ncig kev cai.

4. ** Txoj Kev Thov:**
- ** Txau: ** Lubricants tuaj yeem siv tau siv cov tshuaj tsuag lossis cov tshuab tshuaj tsuag, kom ntseeg tau tias muaj kev tiv thaiv txawm tias nyob rau saum npoo ntawm cov yeeb nkab ua vaj tse.
- ** Txhuam / Rolling: ** Rau cov ntawv me me lossis thaj chaw uas yuav tsum tau ua kom raug, lubricants tuaj yeem siv tau manually siv txhuam los yog cov menyuam.
- ** Txhaj tshuaj:** Qee zaum, cov roj ntsha tuaj yeem raug txhaj ncaj qha rau hauv qhov chaw nruab nrab ntawm cov yeeb nkab thiab cov av ib puag ncig lossis lwm cov kav dej.

5. ** Kev txiav txim siab rau kev xaiv:**
- ** Cov Kev Xav Tau Ntawm Txoj Haujlwm: ** Xav txog cov kev xav tau tshwj xeeb ntawm qhov project, suav nrog cov av, txoj kab uas hla ntawm cov yeeb nkab, thiab txoj kev teeb tsa, xaiv cov roj nplua nyeem uas tsim nyog tshaj plaws.
- ** Cov Kev Cai Ib puag ncig: ** Ua kom muaj kev ua raws li cov cai hauv cheeb tsam ib puag ncig hais txog kev siv thiab pov tseg cov roj nplua nyeem, tshwj xeeb tshaj yog nyob rau thaj chaw muaj kev cuam tshuam.
- **Compatibility:** Txheeb xyuas kev sib raug zoo nrog cov ntaub ntawv koom nrog hauv txheej txheem kev teeb tsa, suav nrog cov khoom siv yeeb nkab thiab cov txheej txheej lossis cov ntaub ntawv.

6. ** Cov Hom Phiaj Ua Lag Luam thiab Cov Chaw Muag Khoom: **
- Tshawb nrhiav cov khoom lag luam ua lag luam thiab cov chaw muag khoom ntawm cov yeeb nkab roj lubricants, xav txog yam xws li cov khoom lag luam zoo, lub koob npe nrov, thiab cov neeg siv khoom txhawb nqa.

qhob yeeb nkab lubricants yog qhov tseem ceeb rau kev yooj yim rau kev txhim kho du ntawm cov kav dej, txo kev sib txhuam, tiv thaiv kev puas tsuaj, thiab txhim kho kev tsim kho. Nkag siab txog hom, cov khoom, cov txheej txheem kev thov, thiab kev xaiv cov txheej txheem ntawm cov lubricants no yog qhov tseem ceeb rau kev ua tiav cov yeeb nkab installation.
