Lub cev lub zog ntawm kerosene
Cov kerosene ntshiab yog xim tsis muaj xim, pob tshab ua kua uas yog daj ntseg daj thaum nws muaj impurities. Ntxub yaim. Qhov kub npau npau yog 180-310 ° C (tsis yog tsis kiag li, nws feem ntau hloov raws li cov kev mob tshwj xeeb thaum lub sijhawm ua khoom), thiab qhov chaw txias txias yog -47 ° C (-40 ° C rau JET A). Qhov hnyav nruab nrab cev muaj li ntawm 200 txog 250. Qhov ceev yog 0.8 g / cm3. Melting point-40 ° C lossis ntau dua. Lub kinematic viscosity ntawm 40 ° C yog 1.0 txog 2.0 hli 2 / s. Insoluble hauv dej, soluble hauv cawv thiab lwm cov organic solvents. nrov nchav. yooj yim. Tom qab hloov mus, nws yog sib xyaw nrog huab cua los ua cov tshuaj sib tov. Qhov qhib tawg yog 2-3%. Ua kom tiav kev sib xyaw, tag nrho cov duab ci ci, cov nplaim hluav taws xob ruaj khov, tsis muaj pa taws dub, tsis muaj pob zeb, tsis muaj qhov tsis pom tseeb, tsis muaj kuab paug rau ib puag ncig.
