TS-1. Roj rau cov tsheb tis
Cov yam ntxwv ntawm ntau lawm technology
Ua raws li cov kev cai ntawm GOST 10277-86, kerosene qib TS-1 yog siv nyob rau hauv dav hlau uas siv subsonic speeds. Lub tshuab ntawm nws cov kev tsim khoom tsis txawv ntawm qhov feem ntau lees txais, tshwj tsis yog cov kev cai nruj uas txwv tsis pub muaj leej faj thiab leej faj-muaj impurities. Yog li ntawd, tom qab cov txheej txheem ntawm distillation ntawm hydrocarbon raw cov ntaub ntawv, cov khoom semi-tiav lawm yuav tsum tau hydrotreatment los yog demercaptanization - cov txheej txheem ntawm xaiv desulfurization ntawm kerosene nyob rau hauv lub xub ntiag ntawm nickel-molybdenum catalysts thiab hydrogen ntawm cov txheej txheem kev khiav hauj lwm kub ntawm 350 .. .400 ° C thiab siab ntawm 3,0 ... 4,0 MPa. Raws li qhov tshwm sim ntawm qhov kev kho mob no, tag nrho cov muaj sulfur ntawm cov hauv paus chiv keeb yog hloov mus rau hydrogen sulfide, uas yog tom qab sib cais, oxidized thiab tshem tawm mus rau hauv cov huab cua nyob rau hauv daim ntawv ntawm gaseous khoom.
Cov ntsiab lus ntawm sulfur txo qis hauv kerosene TC-1 ua rau txo qis hauv cov txheej txheem oxidative uas tshwm sim hauv lub cav khiav. Lawv pab txhawb rau qhov tsim ntawm qhov chaw deposits ntawm qhov chaw, vim li ntawd, lub zog ntawm cov hlau yog txo.
GOST 10227-86 muab rau ob qib ntawm kerosene TS-1, uas txawv ntawm lawv cov kev ua tau zoo thiab thaj chaw ntawm kev siv lub ntsiab lus.
Nta
Kev txiav txim siab ntawm cov khoom lag luam hauv nqe lus nug yog yooj yim - cov ntawv txhais tau hais tias nws yog Aircraft Roj, tus lej txhais tau hais tias qhov sib lawv liag ntawm cov feem ntawm cov khoom siv roj tshwm sim thawj zaug, piv txwv li, ntawm qhov tsawg kawg nkaus qhov ntsuas kub - los ntawm 150.ºC.
Cov yam ntxwv tseem ceeb ntawm lub cev thiab tshuaj lom neeg ntawm cov roj, uas yog normalized los ntawm GOST 10227-86, tau nthuav tawm hauv lub rooj:
| Parameter npe | chav tsev ntawm kev ntsuas | Tus nqi | |
| Rau TS-1 hwm | Rau TS-1 qib thawj | ||
| Qhov tsawg kawg nkaus ceev ntawm chav tsev kub | t / m3 | 0,780 | 0,775 |
| Kinematic viscosity ntawm chav tsev kub, tsis siab dua | hli2/ nrog | 1,30 | 1,25 |
| Yam tsawg kawg ntawm daim ntawv thov kub, | 0С | -20 | -20 |
| Yam tsawg kawg nkaus tus nqi calorific | MJ/kg | 43,12 | 42,90 |
| Yam tsawg kawg flash point | 0С | 28 | 28 |
| Loj feem ntawm sulfur, tsis muaj ntxiv | % | 0,20 | 0,25 |
Tus qauv kuj tswj cov hmoov tshauv ntawm cov roj, nws cov corrosivity thiab thermal stability.
Nrog kev txwv, nws raug tso cai siv cov roj no nyob rau sab qaum teb thiab thaj tsam arctic, nrog rau lub sijhawm khaws cia ntev, ntau dua peb xyoos (kev sib cais yog ua tau, yog li qhov tsim nyog ntawm cov roj av no yog txiav txim siab los ntawm cov txiaj ntsig ntawm kev sim ntxiv) .
Khoom thiab cia
Cov fractional muaj pes tsawg leeg ntawm kerosene TS-1 contributes rau:
- Uniform volatility ntawm cov roj, uas ua kom muaj qib siab ntawm combustion.
- High zog siv guaranteeing yam tsawg kawg nkaus noj.
- Ntxiv fluidity thiab pumpability, uas txo cov kev siv ntawm deg deposits nyob rau hauv cov roj kab thiab aircraft engine qhov chaw.
- Cov khoom zoo tiv thaiv hnav (muab los ntawm qhov muaj cov khoom siv ntxiv uas ua rau muaj zog tiv thaiv hluav taws xob zoo li qub).
Thaum cov roj khaws cia rau lub sijhawm ntau dua 5 xyoos, qhov feem pua ntawm cov khoom siv resinous hauv nws nce, cov kua qaub nce ntxiv, thiab tsim cov khoom siv dag zog tuaj yeem ua tau.
Kev cia cov roj av TS-1 tsuas yog tso cai rau hauv cov ntim ntim, uas yuav tsum tau siv tsuas yog cov cuab yeej pov thawj. Roj vapors spontaneously ignite twb nyob rau ntawm kub tshaj 25ºC, thiab nyob rau hauv ib tug ntim concentration nyob rau hauv huab cua ntau tshaj 1,5%, qhov sib tov yog nquag tawg. Cov xwm txheej no txiav txim siab txog cov xwm txheej tseem ceeb rau kev nyab xeeb - kev pabcuam hluav taws xob teeb pom kev zoo, tiv thaiv hluav taws xob fittings, tsis muaj qhov chaw qhib nplaim taws, muaj txiaj ntsig zoo thiab tso pa tawm.
Nws raug tso cai khaws cov roj av ntawm TS-1 hom nrog rau lwm hom roj zoo sib xws - KT-1, KO-25, thiab lwm yam, yog tias lub tsev khaws khoom tau nruab nrog cov pa roj carbon dioxide lossis ua npuas dej tua hluav taws. Txhua txoj haujlwm nrog roj yuav tsum tau ua nrog cov khoom siv tiv thaiv tus kheej.
