Cov yam ntxwv ntawm lub teeb pom kev zoo kerosene KO-25
Daim ntawv thov
Kev txhais cov npe ntawm cov khoom siv roj hauv nqe lus nug yog yooj yim heev: teeb pom kev zoo kerosene, nrog qhov siab tshaj plaws ntawm qhov siab ntawm 25 hli. Los ntawm txoj kev, qhov siab ntawm cov nplaim taws yog qhov tseem ceeb tshaj plaws ntawm qhov tsim nyog ntawm cov teeb pom kev zoo kerosenes rau qee lub hom phiaj. Yog li, cov qib tau txais los ntawm lub teeb roj feem yog tsim raws li cov kev cai ntawm GOST 11128-65, thiab los ntawm hnyav dua - GOST 92-50. Hauv qhov kawg, kerosene hu ua pyronaphth; nws muaj ntau dua flash point (los ntawm 3500C) thiab khov ntawm qhov kub txaus txaus. Pyronaf yog siv los ua qhov tshwj xeeb ntawm cov teeb pom kev zoo hauv kev ua haujlwm hauv av - mines, tunneling tunnels, thiab lwm yam.
Nyob rau hauv tus txheej txheem ntawm kev qhib combustion, ntau cov tebchaw raug tso tawm uas ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv. Yog li ntawd, nrog ib tug txo nyob rau hauv qhov siab ntawm lub teeb, ib puag ncig txaus ntshai ntawm kerosene txo. Txawm hais tias tsis muaj cov ntaub ntawv tshawb fawb, nws tau tsim kom muaj cov khoom pov tseg tseem ceeb thaum lub sij hawm combustion ntawm teeb pom kev zoo kerosene yog cov khoom me me ntawm cov khoom, carbon monoxide (CO), ntau yam nitrogen oxides (NOx), thiab sulfur dioxide (SO.2). Kev tshawb fawb txog kerosene siv rau kev ua noj lossis teeb pom kev zoo qhia tias cov pa tawm tuaj yeem ua rau lub ntsws ua haujlwm tsis zoo thiab ua rau muaj kev pheej hmoo kis kab mob (xws li tuberculosis), mob hawb pob, thiab mob qog noj ntshav. Yog li ntawd, ib puag ncig nruab nrab ntawm cov teeb pom kev zoo ntawm cov qib roj av tam sim no tau txiav txim siab los ntawm cov kab hauv qab no: KO-30 → KO-25 → KO-20.
Qee qhov xwm txheej, teeb pom kev zoo kerosene KO-25 yog siv los ua roj, hloov TS-1 lossis KT-2 hom, tshwj xeeb tshaj yog vim nws muaj tsawg kawg ntawm cov hydrocarbons ntau dua hauv nws cov muaj pes tsawg leeg thiab emits qee cov tshuaj sooty thaum combustion. Txawm li cas los xij, tus nqi calorific ntawm kerosene KO-25 yog tsawg, uas cuam tshuam tsis zoo rau kev noj cov roj no.
Lub zog ntawm cev nqaij daim tawv
Teeb pom kev zoo kerosenes uas ua los ntawm cov tooj liab-muaj cov roj feem yog cov yam ntxwv ntawm cov ntsuas hauv qab no:
| Parameter | tus nqi ntau | |||
| KO-20 | KO-22 | KO-25 | KO-30 | |
| Qhov ceev, t / m3 | 0,830 | 0,805 | 0,795 | 0,790 |
| Qhov kub ntawm qhov pib ntawm evaporation, 0С | 270 | 280 | 290 | 290 |
| boiling point, 0С | 180 | 200 | 220 | 240 |
| flash point, 0С | 60 | 45 | 40 | 40 |
Txhua hom teeb pom kev zoo kerosene muaj feem pua ntawm cov leej faj (los ntawm 0,55 txog 0,66%).
Cov yam ntxwv ntawm lub teeb pom kev zoo kerosene KO-25 yog suav tias yog qhov zoo tshaj plaws rau kev siv hauv cov qhov cub hluav taws xob lossis cov cua sov ntawm ntau hom. Piv txwv li, nyob rau hauv wick ncu raws li lub capillary hloov ntawm cov roj thiab ntau npaum thiab kub siab ncu nrog chav dav hlau nozzles uas atomize roj los ntawm phau ntawv twj tso kua mis los yog cua sov.
Kerosene KO-20
Cov yam ntxwv ua haujlwm ntawm kerosene qib KO-20 yog tias, txhawm rau txo qhov feem pua ntawm cov leej faj, cov khoom ua tiav ib nrab yog ntxiv rau hydrotreatment. Yog li ntawd, hom no kuj tseem siv rau kev tiv thaiv kev ntxuav thiab ntxuav cov khoom siv hlau, nrog rau cov degreasing degreasing ua ntej priming, painting, thiab lwm yam. Vim tsis muaj toxicity, KO-20 tuaj yeem siv los dilute roj-soluble xim.
Kerosene KO-30
Txij li thaum lub teeb pom kev zoo kerosene KO-30 yog tus cwj pwm los ntawm qhov siab tshaj plaws ntawm qhov siab ntawm qhov siab thiab lub teeb nyem siab thaum lub sij hawm combustion, cov khoom siv roj no yog siv los ua cov kua dej ua haujlwm rau cov khoom siv roj av. Qhov ceev ntawm KO-30 yog qhov siab tshaj plaws ntawm txhua hom teeb pom kev zoo kerosene, yog li nws kuj yog siv rau lub hom phiaj ntawm kev khaws cia ib ntus ntawm cov khoom steel.
