Ntawm ntau yam ntawm txhua yam ntawm cov roj nplua nyeem, graphite roj tsis yog qhov kawg. Nws daim ntawv thov muaj ib cheeb tsam nruj, uas yog vim nws cov khoom.

About graphite in a nutshell…

Txoj kev kho no tau txais nws lub npe los ntawm cov khoom ntawm tib lub npe,

suav nrog nws. Nws yog nws leej twg muab lub lubricant tej yam khoom. Dab tsi yog graphite? Cov tshuaj no yog grey nyob rau hauv cov xim, txawm hais tias nws txawv nyob rau hauv ntau yam ntxoov - los ntawm dub mus rau nyiaj. Nws muaj ib tug metallic sheen. Nws muaj peev xwm tsim cov yeeb yaj kiab nyias thaum rubbed rau ntawm qhov tawv tawv. Raws li nws, cov roj nplua nyeem yog tsim los siv rau hauv ntau qhov kev lag luam.

Graphite roj: nta thiab cov khoom

GOST 3333 80 graphite lubricant - qhov no yog li cas cov tshuaj no tau qhia nyob rau hauv daim ntawv nomenclature ntawm cov lag luam. Rau nws qhov chaw tsim khoom, kev npaj colloid-graphite yog siv. Nyob rau hauv qhov tseeb, xws li ib tug lubricant yog tsis muaj dab tsi ntau tshaj li cov roj av, uas tau thickened nrog calcium xab npum. Graphite nws tus kheej, uas muab lub npe rau cov khoom, tsuas yog 10%. Nws zoo li homogeneous loj, uas muaj xim dub lossis xim av tsaus. Lubricantgraphite nyob rau hauv nws muaj pes tsawg leeg yog yuav luag zoo tib yam rau roj. Qhov sib txawv yog qhov sib ntxiv ntawm graphite thiab kev siv cov roj viscous ntau dua, los ntawm cov khoom tsim.

Graphite roj muaj cov khoom nram qab no:

• Nws tsis evaporate txawm nyob ntawm +150 degrees.
• Nws tsis raug corrosion, yog li nws tiv thaiv cov khoom siv los ntawm xeb.
• Cov khoom no tsis muaj ntau tshaj 3% dej.
• Nws pom zoo siv ntawm qhov kub ntawm -20 txog +70 degrees. Thiab nyob rau hauv qee lub caij nplooj ntoo hlav, qhov ntsuas kub tau tso cai txawm tias qis dua - 20 degrees.

Siv graphite roj

Graphite grease yog siv niaj hnub no hauv ntau qhov chaw ntawm kev tsim khoom:

1. Feem ntau nws yog siv rau cov tshuab hnyav qis. Nyob rau hauv lub tsheb laij teb ncua kev kawm ntawv, nyob rau hauv springs, nyob rau hauv lub bearings ntawm laum khoom (lub pob zeb diamond taub hau heev uas yog siv los rho roj), nyob rau hauv lub zog. Nyob rau hauv tag nrho cov mechanisms, qhov nce nyob rau hauv kuj tshwm sim los ntawm lubrication plays tsis muaj lub luag hauj lwm.



Tab sis rau qhov tseeb, xws li cov kabmob, cov cuab yeej no tsis haum. Nws tuaj yeem ua rau cov khoom puas lossis hnav tawm. Qhov no tau yooj yim los ntawm cov neeg kho tshuab impurities uas yog ib feem ntawm graphite.

2. Graphite roj kuj siv tau rau kev tiv thaiv. Piv txwv li, cov xauv zoo tib yam yog ua tiav nrog nws thaum lub caij ntuj no. Yog li, lawv tsis khov thiab qhib zoo. Txhua yam additives nyob rau hauv muaj pes tsawg leeg ntawm cov khoompab yaj dej khov thiab tshem tawm xeb, yog li tiv thaiv lub xauv mechanism.

Thaum xaiv cov roj nplua nyeem no, koj yuav tsum tau ceev faj heev, vim tsis ntev los no tau muaj cov ntaub ntawv cuav ntau zaus. Yog li ntawd, kev nyiam yuav tsum tau muab rau cov khoom lag luam uas tsim los ntawm cov tuam txhab muaj npe nrov nrog lub koob npe zoo. Thiab nws raug nquahu kom ua kev yuav khoom hauv khw tshwj xeeb. Tom qab tag nrho, kev ruaj khov ntawm cov khoom siv rau ntau lub hom phiaj yog nyob ntawm qhov zoo ntawm cov khoom siv no.
