Ngomhla we-14 kuCanzibe, izifundo ezimbini, “Ukuthelekisa iiFomu zeKhoyili ezingangeni manzi” kunye “noPhuhliso oluQhelekileyo lwaMaqela e-Asphalt angangeni manzi”, zenziwe ngokupheleleyo kwisityalo sokuqala sokuhlola i-asphalt esingangeni manzi sePetroChina.Ezi zizifundo zokuqala ezimbini eziqaliswe emva kokuba isiseko sityhilwe ngomhla wama-29 ku-Epreli.

Njengesiseko sokuqala sovavanyo lwe-asphalt engangeni manzi e-China Petroleum, i-institute yophando yenkampani yeoyile yepetroli kunye neJianguo Weiye Group kunye nezinye iiyunithi ziya kuzibophelela ekukhuthazeni nasekusebenziseni iimveliso ezintsha ze-asphalt ezingangeni manzi, uphuhliso lwentsebenziswano lwe-asphalt entsha engangeni manzi kunye neemveliso ezincedisayo ezinxulumene noko, kunye nophuhliso lwetekhnoloji kolu qeqesho lwe-base Exchange, zenze umsebenzi wophando malunga nokusetyenziswa kwemveliso ye-asphalt engangeni manzi kwimizi-mveliso.Iya kuba sisiseko sokufakelwa kotshintsho kwiimveliso ezintsha kunye nobuchwepheshe obutsha bePetroChina, nto leyo ebaluleke kakhulu ekukhawuleziseni ukukhuthazwa nokusetyenziswa kweemveliso ze-asphalt ezingangeni manzi zePetroChina kunye nokubonelela ngeemveliso ze-asphalt ezingangeni manzi ezingcono nezingabizi kakhulu kushishino olungangeni manzi.

Njengemveliso ephezulu kusapho lwe-asphalt, i-asphalt engangeni manzi iye yaba lolona hlobo lukhulu lwe-asphalt ngaphandle kwe-asphalt yendlela.Kunyaka ophelileyo, intengiso ye-asphalt engangeni manzi e-petroleum eTshayina ifikelele kwi-1.53 ​​yezigidi zeetoni, kunye nesabelo semarike esingaphezulu kwe-21%.
