Phula la malasha, ndi lalifupi la malasha phula phula, malasha phula distillation processing pambuyo kuchotsa zotsalira madzi distillate, ndi wa mtundu wa phula yokumba, makamaka kwa viscous madzi, theka-olimba kapena olimba, wakuda ndi chonyezimira, zambiri amakhala carbon 92 ~ 94%, haidrojeni pafupifupi 4-5%. Phula la malasha ndi chinthu chofunikira kwambiri pokonza phula la malasha ndipo ndi chinthu chosasinthika chopangira kaboni.
Cholinga cha distillation ya phula ndikuyika zinthu zomwe zili ndi mfundo zowira zofananira mu phula kuti zikhale tizigawo tomwe titha kukonzanso ndikulekanitsa zinthu za monomer. Chotsalira chochotsa distillate ndi phula la malasha, lomwe limawerengera 50% ~ 60% ya phula lamalasha.
Malingana ndi mfundo zosiyana zochepetsera, phula la malasha limagawidwa kukhala phula lochepa la kutentha (asphalt wofewa), kutentha kwapakatikati (asphalt wamba), phula lotentha kwambiri (hard asphalt) magulu atatu, gulu lirilonse liri ndi No. 1 ndi No. .
Phula la malasha limagwiritsidwa ntchito makamaka m'magawo otsatirawa:
* Mafuta: Zida zolimba zimatha kusakanikirana ndi mafuta olemera kapena kupanga slurry zomwe zimagwiritsidwa ntchito, zimatha kutengapo gawo posintha mafuta olemera.
Utoto: Utoto womwe umawonjezera rosin kapena turpentine ndi zodzaza pophika mafuta anyumba kapena mapaipi osalowa madzi. Ndi yoyenera panja zitsulo kapangidwe, konkire ndi miyala wosanjikiza madzi ndi wosanjikiza zoteteza, ndipo akhoza utoto ndi utoto kutentha firiji.
* Kumanga misewu, zomangira: zambiri wothira mafuta asphalt, malasha asphalt ndi mafuta phula poyerekeza, pali kusiyana khalidwe ndi durability kusiyana. Phula la malasha ndi losauka mu pulasitiki, losakhazikika mu kutentha, limakhala lolimba m'nyengo yozizira, limafewetsa m'chilimwe, ndipo limakalamba mofulumira.
* Binder: Chitani ma elekitirodi, phala la anode ndi zinthu zina za kaboni, zomwe nthawi zambiri zimasinthidwa phula. Kawirikawiri, asphalt yosinthidwa imakonzedwa kuchokera ku phula la kutentha kwapakati. Ku China, njira yowotchera ketulo nthawi zambiri imatengedwa, ndipo gasi amagwiritsidwa ntchito ngati mafuta kutenthetsa phula mu riyakitala. Pomaliza, asphalt yosinthika yokhazikika imapezeka kudzera pakupatukana ndi granulation.
* Asphalt coke: zotsalira zolimba za malasha pambuyo pa kutentha kwambiri kapena kuchedwa kuphika. Asphalt coke nthawi zambiri amagwiritsidwa ntchito ngati zopangira zida zapadera za kaboni, zomwe ndizofunikira kwambiri popanga zida za semiconductor ndi solar solar. Amagwiritsidwa ntchito kwambiri ngati ma elekitirodi pakuyenga aluminiyamu, zinthu zopangidwa ndi kaboni zopangira zitsulo zamagetsi zamagetsi ndi zida zapadera za carbon zopangira semiconductor.
* Coke ya singano: phula wofewa woyengedwa ndi pretreatment zopangira, kuchedwa kuphika, kuwerengera kutentha kwambiri njira zitatu, zomwe zimagwiritsidwa ntchito makamaka popanga ma elekitirodi ndi zinthu zapadera za kaboni. Zogulitsa zopangidwa kuchokera kuzinthu zake zopangira zimadziwika ndi kutsika kwa resistivity, kuchepa kwa kutentha kwapakati, kukana kutentha kwakukulu, mphamvu zamakina apamwamba komanso kukana kwa okosijeni wabwino.
* Carbon CHIKWANGWANI: CHIKWANGWANI chapadera chokhala ndi mpweya wopitilira 92% wopezedwa kuchokera ku phula poyenga, kupota, pre-oxidation, carbonization kapena graphitization.
* Mafuta amamva, activated carbon, carbon black ndi ntchito zina.
