Tsis-woven hnab-txiav tshuab hauv cov txij nkawm ntawm lubricating roj, tsis-woven hnab-txiav lub tshuab lubricants yuav ua li cas xaiv? Lubricants yuav tsum tau tsuas yog lub nruab lubrication
Tom qab ntawd lawv xaiv yog heev yooj yim, tab sis feem ntau ntawm lub sij hawm nws yog ib qhov tsim nyog yuav tau kho lawv sab hauv thiab sab nraud lubrication mus rau ib qho raws li qhov zoo tshaj plaws.
Lub nruab thiab sab nrauv lubrication ntawm lub roj nplaum yog txiav txim los ntawm nws cov tshuaj muaj pes tsawg leeg, polarity, thiab solubility nyob rau hauv lub polymer yaj. Piv txwv, nyuaj
Cov kab mob lipid monoglycerides tau yaj hauv polyvinyl chloride yaj thiab muaj ib feem ntawm lub cev muaj lubrication. Nws lubrication muaj nuj nqi los ntawm ob pawg polar hydroxyl pawg hauv molecule
Siv; Ntsig, ntawm qhov tod tes, tsuas muaj lub cev tsis muaj lubrication vim nws tsis muaj cov hydroxyl pawg hauv nws cov molecules. Ntawm chav kawm, lubrication muaj nuj nqi kuj cuam tshuam los ntawm cov impurities uas muaj nyob hauv lub roj nplua nyeem
Thiab lwm yam khoom siv ntxiv.
Muaj ntau hom lubricants siv rau hauv lub hnab uas tsis yog-lub hnab ntim ua cov tshuab, xws li cov khoom siv lignite, paraffin quav, ntxhia roj, tsiaj thiab zaub roj thiab lwm yam ntuj tso
Muaj ntau hom qes cev tsis haum molecular polymers xws li tsis tshua muaj cov tshuaj fluorine, molecular fluorine resin, silicone roj, tsis tshua muaj ceev polyethylene, thiab lwm yam., Kheev siv nyob rau hauv kev sib txuam
Khoom, xws li stearic acid, stearic acid soap, acid ester. Thiab amides.
Xyoo 1981, ntau tshaj li ntawm 10,000 tons ntawm lubricants tau siv rau cov khoom lag luam hauv Teb Chaws Asmeskas, nrog 45% ntawm cov khoom amides thiab 35% ntawm stearic acids thiab lawv cov derivatives
Qhov thib ob yog qhov sib xyaws sib txuas thiab ua li ntawd. Qee lub lubricants, xws li oleic acid amide, stearic acid amide, fatty acid hlau ntsev zog (fatty acid cadmium) thiab zoo li kuj zoo rau lawv tus kheej
Nws yog ib tug neeg sawv cev ntawm kev ua kom tawv nqaij. Tsis-woven hnab-ua tshuab lubricating roj ntev li 0.5% yuav ua rau zaj duab xis muaj ib tus zoo du. Ntawm chav kawm silicon dioxide, av nplaum no
Chav kawm ib lub cev kuj yog cov siv tshuaj tiv thaiv ntev tshaj plaws, nrog rau ntau npaum li ntawm 0.1-1.0%. Lawv feem ntau hu ua cov neeg ua haujlwm qhib.
