Khoom nta thiab siv
Kheej kheej sphhalt feem ntau softens saum [° C, raws li lub npe qhia. Cov kheej kheej asphalt muaj cov tsos ntawm ib tug me me nplej-zoo li tus kheej nrog lub cev tsis muaj zog ntawm 0-2mm. Txoj kev sieving yog 80%, thiab nws muaj cov yam ntxwv ntawm cov tshuaj carbon, toluene insoluble cov tshuaj, thiab cov qoob loo huv av. Dav siv los ua kev ntxiv nyob rau hauv lub zog rauv av nkos, tawg ramming cov khoom siv, thiab ua kom cov pa roj carbon monoxide, thiab cov pa roj carbon monoxide, thiab txhim kho cov khoom siv carbon monoxide, thiab ua kom cov pa roj carbon monoxide, thiab cov pa roj carbon monoxide, thiab txhim kho cov khoom siv pa roj carbon monoxide
Npaj txheej txheem
Cov kheej kheej asphalt yog ua los ntawm cua sov, yaj, txau, thiab txias thee quav thee tar asarhalt. Ntxiv cov raw asphalt siv nyob rau hauv kev sim rau asphalt rhuav tshem Kettle thiab ua kom sov rau kev xaus. Nyob rau tib lub sijhawm, tig rau lub zog hluav taws xob chev, thiab cov kua asphalt yuav muab tshuaj tsuag tawm ntawm lub nozzle, thiab atomized rau hauv cov pa me me. Asphalt txhais yog ib txwm txias rau hauv cov khoom noj txias dhau los ntawm kev ntsuas cua txias rau kev faib tawm, ua rau cov khoom siv ayerical
Cov khoom no muaj cov yam ntxwv ntawm cov carbon, insoluble toluene, cov ntsiab lus zoo, thiab cov tshauv qis. Nws yog dav siv hauv lub zog ua kom sov ua kom sov cov khoom siv hlau nuv khoom, hluav taws xob ua kom tau cov ntaub ntawv kho, ramming thiab casting cov ntaub ntawv refractory. Nws yog ib qho ntxiv rau cov ntaub ntawv carbon thiab tuaj yeem ua lub luag haujlwm hauv kev sib raug zoo hauv kev sib koom tes thiab kev txhim kho cov khoom lag luam muaj peev xwm tiv thaiv kom kub thiab kev yaig
