I-Coal Tar Pitch njenge-asphalt powder yi-organing yonyango lwe-organic ye-sleure enokuthi ithintele ukuvuza, ukunqanda ukuwa, inyibilike, inciphise ukuntywila;

I-Lubrice yokunciphisa i-Toung, kunciphisa amandla okuphakamisa kunye nokuphakamisa izixhobo zokumba, kusongeza ubomi benkonzo ye-bill, kwaye uthintele kwaye unciphise ukumbandela;

Yenza i-cundes emnyama kunye ne-our mud yokomeleza udonga olukhazimpheli. Lawula ukupheliswa kwenkunkuma;

1, Lawula amaqondo obushushu aphezulu aqhekeza odaka; Ingasetyenziswa ngokudibeneyo kunye nabanye abantu abancinci abancinci. Luhlobo lokunamathela olunokusetyenziswa njengombhexeshi wesamente kunye nodaka kwimimandla yeoyile. Inokonyusa amandla kwaye inxibe isifo sokunganyangeki, sinike iimpawu ezinamahlalo sesamente etyibilika, kwaye ke yandisa ukuzinza kweendonga zeoyile kunye nemibhobho.

I-2, i-coal tetch inokusetyenziswa njengesongezo ukuphucula ukufakwa kwamanzi kunye nokulawula ubushushu obune-oyile yesamente. I-viscosity ephezulu kunye nokuxhathisa kobushushu obuphezulu kwi-pitch yamalahle inokugcina uzinzo lokuqhuba kwiindawo ezinamaqondo obushushu, ukuqinisekisa ukusebenza kwesamente.

I-3, i-Coal Tatch inokusetyenziswa njengesongezo seoyile yeoyile yeoyile. Inokunciphisa isimo se-sediment kunye neoyile kwi-oyile imibhobho emthobe, kwaye iphucule i-oyile imveliso kakuhle kunye nolwelo.

I-4, i-pitch ye-tet ye-tetch inemisebenzi eyahlukeneyo yoosongezelelo, kubandakanya ii-bibors, ukuphuculwa kwe-viscosity, i-viscosity, enokuphucula ukuqhuba kunye nokuzinza kakuhle kwemithombo yeoyile.
