Dab tsi yog qhov yuav tsum tau ua rau cov roj siv hauv lub tshuab nqus tsev vacuum?
Jun 01, 2019| Dab tsi yog qhov yuav tsum tau ua rau cov roj siv hauv lub tshuab nqus tsev vacuum? Hnub no Xiaobian tau qhia luv luv hauv qab no.
1.Vim tsawg vapor siab
Qhov no yog qhov tseem ceeb tshaj plaws ntawm lub tshuab nqus tsev twj roj. Vim tias lub tshuab nqus tsev yuav tsum muaj lub tshuab nqus tsev siab, paraffin-based nqaim-txiav lubricating roj feem ntau yog siv. Rau diffusion lub tshuab nqus tsev twj tso kua mis, silicone roj los yog lwm yam roj hluavtaws uas tsis muaj vapor siab yuav siv tau.
2. Tsim nyog viscosity thiab zoo viscosity-kub yam ntxwv
Lub ntim sab hauv ntawm lub tshuab nqus tsev twj tso kua mis yog tas li hloov mus rau ib qho kev ua kom qaug zog, thiab cov roj lubricating yuav tsum muaj qhov tsim nyog viscosity thiab viscosity-kub yam ntxwv.
3. Zoo thermal oxidation stability
Lub tshuab nqus tsev twj tso kua mis tsis tu ncua ntawm kev kub ceev. Vim muaj kev sib txhuam ceev ceev ntawm cov zawv zawg thiab lub twj tso kua mis lub cev, cov roj kub tau nce, thiab cov roj tau yooj yim oxidized thiab decomposed. Tshwj xeeb, lub twj tso kua mis diffusion feem ntau ua haujlwm nyob rau hauv ib puag ncig kub, kom lub vapor siab hauv qhov system nce. Cov qib ntawm lub tshuab nqus tsev yog qis, yog li lub tshuab nqus tsev twj tso kua mis yuav tsum muaj thermal oxidation stability zoo.
4. Zoo corrosion kuj thiab demulsibility
Yog tias lub tshuab nqus tsev nqus tau nqus cov pa corrosive, nws yuav ua rau cov roj thiab corrode cov khoom hauv lub twj tso kua mis. Cov pa nqus pa feem ntau muaj cov dej vapor condensate, uas ua rau lub tshuab nqus tsev twj tso kua mis rau emulsifie thiab corrode hlau. Yog li ntawd, nws yuav tsum muaj qhov zoo corrosion kuj thiab emulsification kuj. Kev sib deev.
5. Siab dua flash point
Nws yog qhov tseem ceeb uas lub tshuab nqus tsev twj tso kua mis tsis nqa cov khoom siv lub teeb, thiaj li tsis cuam tshuam rau cov roj saturated vapor siab.
