Ngomhlaka-14 Meyi, izifundo ezimbili, “Ukuqhathanisa Ama-Coil Formulations Angangeni Manzi” kanye “Nokuthuthukiswa Okujwayelekile Kwamaqembu E-Asphalt Angangeni Manzi”, zenziwa ngokugcwele esitshalweni sokuqala sokuhlola i-asphalt esingangeni manzi sePetroChina.Lezi yizifundo ezimbili zokuqala ezaqalwa ngemuva kokwethulwa kwesisekelo ngo-Ephreli 29.

Njengesisekelo sokuqala sokuhlola i-asphalt engangeni manzi se-China Petroleum, isikhungo socwaningo lwenkampani kawoyela kaphethiloli kanye neJianguo Weiye Group kanye namanye amayunithi bazozibophezela ekukhuthazeni nasekusebenziseni imikhiqizo emisha ye-asphalt engangeni manzi, ekuthuthukisweni ngokubambisana kwe-asphalt entsha engangeni manzi kanye nemikhiqizo ehlobene nayo, kanye nasekuthuthukisweni kobuchwepheshe kulolu qeqesho lwe-Base Exchange, benze umsebenzi wocwaningo ngokusetshenziswa kwezimboni kwemikhiqizo ye-asphalt engangeni manzi.Izoba yisisekelo sokuthuthukiswa kokuguqulwa kwemikhiqizo emisha kanye nobuchwepheshe obusha bePetroChina, okubaluleke kakhulu ekusheshiseni ukukhuthazwa kanye nokusetshenziswa kwemikhiqizo ye-asphalt engangeni manzi yePetroChina kanye nokuhlinzeka ngemikhiqizo ye-asphalt engangeni manzi engcono futhi engabizi kakhulu embonini engangeni manzi.

Njengomkhiqizo osezingeni eliphezulu emndenini we-asphalt, i-asphalt engangeni manzi isibe uhlobo olukhulu kakhulu lwe-asphalt ngaphandle kwe-asphalt yomgwaqo.Ngonyaka odlule, ukuthengiswa kwe-asphalt engangeni manzi e-petroleum eShayina kwafinyelela amathani ayizigidi ezingu-1.53, kanti isabelo semakethe sasingaphezu kuka-21%.
