CNPC Kunlun paraffin Ciab
Paraffin waxes yog cais los ntawm crude roj thaum lub sij hawm ntau lawm ntawm lub teeb (distillate) lubricating roj. Cov waxes yog categorized los ntawm roj cov ntsiab lus thiab cov neeg kawm ntawv ca. Lub crudest versions poob mus rau hauv lub slack ciab qeb thiab muaj nyob nruab nrab ntawm 5% mus rau 20% cov roj. Tom ntej no rau cov kauj ruam ntawm kev cai yog teev waxes muaj ntawm 1% mus rau 5% roj. Qhov siab tshaj plaws qib ntawm kev cai yog lub siab kom zoo zoo ciab. Nkaus refined paraffin waxes muaj tsawg tshaj li 0.5% roj thiab tau hydro kho los yog av nplaum kho kom tshem tawm impurities thiab xim. Cov uas ua waxes yog dej ntshiab, tsw dawb, thiab feem ntau cov zaub mov qib.
txheej txheem
Qhov no yog ib tug tag nrho kom zoo zoo paraffin ciab khoom ua los ntawm tej yam ntuj tso crudeased roj uas muaj ciab los ntawm tus txheej txheem
cov kauj ruam ntawm kuab deoiling thiab hydrotrating.
khoom yav tom ntej
Cov khoom no yog ib qho ntxhiab khoom nyob rau hauv ambient kub, yuav ua tau molten los ntawm cov cua kub. Cov khoom no
combustible, ntawm uas tsis muaj cua sov thiab fais conductivity thiab muaj zog ya tuav-up.
Tswv yim usages
Cov khoom yog dav siv nyob rau hauv cov raug kev HF tej hub, carbon ntawv, stylus ntawv, leej casting, thiab
absorbing kho kom zoo nkauj phaj thiab lwm yam, raws li tau zoo raws li nyob rau hauv lub ntim, hluav taws xob, textile, tswm ciab, xaum xim, match thiab lwm yam
kev lag luam liaj teb. Nyob rau hauv tas li ntawd, nws yuav siv tau raws li raw khoom, additive los yog modifier nyob rau hauv fabrication ntawm cov khoom kim heev taws tswm ciab
thiab ntau hom muaj los yog civil siv tswm ciab, kuj raws li nyoos muaj nyob rau hauv formulation ntawm lub ntsej muag qab zib thiab
lwm yam ntau tshuaj pleev ib ce.
