Mineral roj, ib nrab synthesis, tag nrho cov synthesis ntawm peb. Qhov txawv ntawm lawv yog dab tsi?

2023-08-31

Txhawm rau kom lub cav ua kom zoo, cov txheej txheem roj evolution thiab kev loj hlob, raws li kev faib tawm nrog cov roj ntxhia, ib nrab synthesis, tag nrho cov synthesis ntawm peb. Qhov txawv ntawm lawv yog dab tsi? Bond - ib qho kev daws teeb meem rau koj.

Cov muaj pes tsawg leeg ntawm cov roj

Cov roj feem ntau faib ua ob ntu: cov roj hauv paus thiab cov khoom ntxiv

Lub hauv paus roj yog lub ntsiab tseem ceeb ntawm cov roj los txiav txim siab cov yam ntxwv ntawm cov roj, muaj kev cuam tshuam ncaj qha rau cov nyhuv ntawm lubrication, roj additives rau qee qhov tsawg, siv los tsim thiab txhim kho cov roj hauv paus kev ua haujlwm tsis txaus.

01 ntxhia roj

Mineral roj yog lub hauv paus ntawm cov roj crude, cov txheej txheem ntau lawm yog raws li nram no: nyob rau hauv cov txheej txheem ntawm cov roj refining, fractionation tawm cov roj av muaj txiaj ntsig, hauv qab ntawm cov roj seem thiab cov roj ntxhia ua kom zoo. Cov roj ntxhia, cov laus tshaj plaws, tab sis technically muaj qee qhov kev txwv ntawm lub sijhawm thiab cov nyhuv lubrication yog qhov txwv

02 ib nrab ntawm cov roj hluavtaws hluavtaws

Nrog rau kev txhim kho tas mus li ntawm lub cav, qhov kev thov rau cov roj yog ntau dua thiab siab dua, cov kws tshawb fawb yuav tsum tau hloov qee cov roj ntxhia, hluavtaws ester lossis polyolefin dua thiab cov khoom ntxiv, ib nrab yog tsim cov roj hluavtaws hluavtaws, txheeb ze rau "cov khoom xyaw ntuj" cov ntxhia. roj, semi-synthetic cav roj kev ua tau zoo yog ntau lub hom phiaj, lubrication nyhuv yog zoo dua

03 tag nrho hluavtaws cav roj

Lub tshuab hluav taws xob ua hluav taws xob tag nrho yog cov khoom lag luam ntawm cov cuab yeej siv niaj hnub no, tag nrho los ntawm cov roj hluavtaws hluavtaws tsis sib xyaw nrog cov roj ntxhia, vim tias cov txheej txheem molecular zoo, nrog kev sib txhuam me me, muaj zog oxidation tsis kam, ntev roj hloov lub sij hawm.

Hauv luv luv, kev ua tau zoo tshaj plaws

Thawj siv nyob rau hauv lub tsheb, ces muab tso rau hauv pej xeem
