Kev ntsuas dav dav thiab kev siv TEP-15
Tep-15 roj (tus lej nyob rau hauv lub npe hom txhais tau tias lub nominal viscosity ntawm no lubricant ntawm 100ºC) muaj qhov tsis tshua muaj gel taw tes thiab muaj cov tshuaj tiv thaiv hnav thiab cov khoom siv siab heev. Lub acidity ntawm cov khoom yog tsawg, uas ua rau nws muaj peev xwm muab cov iav qhov chaw (tshwj xeeb tshaj yog qhib) nrog txaus siab anti-corrosion yam ntxwv. Rau zus tau tej cov Tep-15 iav roj, qib roj nrog ib tug siab feem pua ntawm cov resins yog siv, yog li cov khoom kawg yog tau tsuas yog los ntawm high-zoo distillation thiab distillation ntawm feedstock.
Nyob rau hauv lub neej txhua hnub, cov roj nplua nyeem no feem ntau siv los tsim lwm hom roj iav, siv Tep-15 nigrol ua ib qho ntxiv (txawm li cas los xij, qhov no tsuas yog tso cai rau cov tsheb qub hauv tsev, lub zog hypoid uas tsis tseem ceeb rau kev hloov hauv cov yam ntxwv viscosity pom zoo).
Tus nqi qis ntawm cov khoom siv tau ua pov thawj qhov kev xav tau hloov pauv ntau zaus yog tias lub tsheb siv hnyav heev. Qhov no tau piav qhia los ntawm qhov tseeb tias nrog kev sib cuag ntau ntxiv, cov roj sib cais, feem pua ntawm cov neeg kho tshuab impurities nce, thiab kev sib cuag kub nce, uas ua rau kom nrawm hnav ntawm cov ncej thiab lub zog.
Cov yam ntxwv ntawm qhov muaj pes tsawg leeg thiab kev ua haujlwm
Tsis zoo li ntau hom Tad-17, cov khoom hauv nqe lus nug muaj qis dua viscosity. Qhov no txo qhov kev siv zog thaum hloov lub zog ntawm lub tsheb, tshwj xeeb tshaj yog, nyob rau hauv tsis tu ncua ntawm nws daim ntawv thov. Ib feem ntawm cov additives rau Tep-15 tsis muaj ntau yam kev txhim kho nyob rau hauv huab cua siab, tab sis ib tug nce nyob rau hauv lub thickening kub: los ntawm 0 ... -5ºLos ntawm -20…-30ºC. Qhov no ua rau kom muaj kev ntseeg siab ntawm cov neeg kho tshuab xa khoom ntawm cov tsheb laij teb ntawm qhov ntsuas kub qis, nrog rau thaum lub sijhawm kaw lub cav.
Cov yam ntxwv ntawm Tep-15 hom kis tau tus mob roj:
- Qhov ceev, kg / m3 - 940… 950.
- Viscosity, cSt ntawm 100ºC, tsis ntau tshaj 16.
- Qhov siab tshaj plaws pub feem pua ntawm impurities, %, tsis ntau tshaj - 0,03.
- Kev tiv thaiv corrosion - yuav tsum ua raws li cov cai ntawm GOST 2917-76.
- Cov khoom siv siab tshaj plaws: phosphorus (tsis pub tsawg dua 0,06%), sulfur (tsis ntau tshaj 3,0%).
- Tso cai nce viscosity ntawm qhov kub thiab txias tshaj 140ºC, %, tsis ntau tshaj - 9.
- Tshuaj aggressiveness nyob rau hauv relation mus petrol-roj-resistant roj hmab - ua tau raws li qhov yuav tsum tau ntawm GOST 9030-74.
Cov roj nplua nyeem muaj cov tshuaj toxicity tsawg (tseem ceeb pawg 4 raws li GOST 12.1.007-76) thiab yog tus cwj pwm los ntawm lub neej ntev ntev (txog li 5 xyoos, raws li qhov tsim nyog).
Kev txwv
Tsawg feem pua ntawm cov additives, txawm hais tias nws muab tus nqi qis rau cov khoom, tsis tuaj yeem lav qhov delamination ntawm lubricant thaum lub sijhawm ua haujlwm ntev. Yog li ntawd, txhua txhua 20 ... 30 txhiab kilometers ntawm lub tsheb, xws li iav roj yuav tsum tau hloov.
Raws li cov khoom siv hluav taws xob hluav taws xob, Tep-15 yuav tsum tau siv nrog ceev faj nyob ze ntawm qhov chaw qhib hluav taws, nrog rau ze rau qhov chaw hluav taws kub. Thaum khaws cia rau hauv warehouses, lawv yuav tsum tau ventilated, vim hais tias ntawm cov concentration ntawm vapors ntawm cov khoom nyob rau hauv cov huab cua txo mus rau 3 ... 4 mg / m.3.
Kev sib xyaw ua ke ntawm cov tshuaj depressant additives yuav tsum tsis txhob tsawg tshaj li 1,3%, vim hais tias cov kev pheej hmoo ntawm crystallization ntawm cov roj Cheebtsam yuav nce. Raws li qhov tshwm sim, kev ua haujlwm ntawm txhua qhov kev sib kis ntawm lub tsheb yuav nyuaj dua thiab lub zog sib koom ua ke nce ntxiv.
Qee cov tuam txhab tsim cov roj Tep-15 iav hu ua TM-2-18. Ntawm no, thawj tus lej qhia cov pab pawg ua haujlwm raws li GOST 17479.2-85, thiab thib ob - tus nqi qis tshaj plaws ntawm 100ºC. Lwm yam kev mob rau kev siv cov roj nplaum no yog txiav txim siab los ntawm cov cai ntawm GOST 23652-79.
