Coal tar secch seasphalt poda ndeye multifaunical organic inodhonzera mumiriri wekurapa, kudzivirira kuparara, lubricate, kuderedza kuramba, uye inhibit kucherwa;

Lubrication inoderedza dhonza, inoderedza kusimudza kugona uye torque yekukwevera maturusi, inowedzera hupenyu hwebasa rekukwevera mabheti, uye rinodzivirira nekudzora kusanamira.

Fomu yakaonda uye yakaoma matope ematowo kuti isimbise madziro ellbore. Dzora yakakwira-tembiricha yekushomeka;

1, Dzora yakakwirira-tembiricha inocheka simba rematope; Inogona kushandiswa mukubatanidzwa nemamwe madhiri ekurapa ematope. Ndiwo rudzi rwezvinonamatira izvo zvinogona kushandiswa seinosungwa kwesimendi uye muchetya muminda yemafuta. Inogona kuwedzera simba uye kupfeka kurwisa dhaka, inopa zvivakwa zve simende slurry, uye nekudaro kuwedzera kugadzikana kwemadziro ezvemafuta uye pombi.

2, Coal tar pitch inogonawo kushandiswa seyakawedzera kuvandudza kufambisa fluid viscosity uye kudzora tembiricha musimbe musimbisi wezvemafuta. Iyo yakakwira viscosity uye yakakwira-tembiricha kuramba yemarata tar pitch inogona kuchengetedza kugadzikana kwemvura yekukwevera mumamiriro ekunze, ichisimbisa kushanda kwekusimbisa.

" Inogona kuderedza sediment neoiri pasi pamafuta emapipi pipi, uye kugadzirisa mafuta kugadzirwa kwakanaka uye fluidity.

4, marasha emarasha ane mabasa akasiyana siyana mune zvemafuta ekuwedzera, kusanganisira mabhandi, maCoublants, etc., anokwanisa kuvandudza kunyatsoita uye kugadzirwa kwemafuta, kuve nechokwadi chekugadzikana uye fluidity miganho yemafuta.
