Kufurira kweasphalt kusanganisa chirimwa hachigone kuderedzwa. Iyo zvakare ine simba rakakura pakudziya kwekuita kweasphalt pombi. Izvi zvinodaro nekuti iyo yakakosha kuita zviratidzo zveasphalt, senge viscosity uye sarufa zvemukati, zvine hukama neasphalt yekusanganisa chiteshi. Kazhinji kutaura, iyo yakakura viscosity, iyo yakaipisisa iyo atomization athari, iyo inokanganisa zvakananga kushanda kwekushanda uye kushandiswa kwemafuta. Sezvo tembiricha inokwira, viscosity yemafuta anorema inodzikira zvishoma nezvishoma, saka mafuta epamusoro-viscosity anofanirwa kupiswa kuti afambiswe zvakanaka uye atomization.

Naizvozvo, pamusoro pekunzwisisa ayo akajairwa zviratidzo, zvinodikanwa zvakare kugona kwayo viscosity-tembiricha curve paunenge uchiisarudza kuti ive nechokwadi chekuti kupisa kunogona kuita kuti asphalt isvike viscosity inodiwa neanopisa isati yasvika atomization. Paunenge uchitarisa iyo asphalt circulation system, yakawanikwa kuti kutonhora kwepombi yeasphalt haina kuzadzisa zvinodiwa, zvichiita kuti asphalt mupombi isimbise.
Zvikonzero zvikuru ndezvizvi:
1. Tangi yepamusoro yemafuta emafuta anopisa yakaderera zvikuru, zvichiita kuti kusvibiswa kusina kunaka kwemafuta ekupisa;
2. Iyo yemukati chubhu yehuviri-layer chubhu ndeye eccentric
3. Pombi yemafuta ekupisa yakarebesa;
4. Pombi yemafuta ekupisa haina kutora matanho akakodzera ekudzivirira, nezvimwewo Izvi ndizvo zvinhu zvikuru zvinokanganisa kupisa.
