Kusukela ngo-2004 kuze kube manje, eminyakeni eyi-9 edlule, i-Petroleum Resin ngiye ngakubona ukushintshashintsha kwamanani kusuka ku-C5 izinto zokusetshenziswa kuya emikhiqizweni ye-petroleum resin. Ngaleso sikhathi, izinto zokusetshenziswa zekhabhoni ezinhlanu zazingamayuan/ton angu-3,600, i-Petroleum Resin petroleum resin yayingu-8,000 yuan/ton, Petroleum Resin futhi intengo yemikhiqizo eqediwe yayiyiphinda kabili inani lezinto zokusetshenziswa. Ngaleso sikhathi, ukuqonda kwasekhaya kwe-Petroleum Resin kwe-petroleum resin kwakunganele, i-Petroleum Resin ngoba abasebenzisi abaningi babesajwayele ukusebenzisa i-rosin. Kwaze kwaba kamuva lapho i-rosin ihlushwa izinhlekelele zesimo sezulu futhi ukukhiqizwa kwe-rosin kwanda. Ama-petroleum resin aya ngokuya amukelwa emakethe yamazwe ngamazwe. Abanye abantu baseShayina bazama kancane kancane ukufaka i-rosin esikhundleni se-petroleum resins ngokwengxenye noma ngokuphelele. Kungcono kune-rosin.
Ngekota yesine ka-2011, i-Petroleum Resin amanani entengo ye-rosin ne-petroleum resin ehla. I-Rosin yehle ngaphansi kwe-10,000 yuan, i-Petroleum Resin yehle ngaphezu kwama-50%. Intengo evamile ye-petroleum resin ingu-11,800 yuan/ton. Kodwa-ke, i-Petroleum Resin intengo yamanje yezinto zokusetshenziswa ze-C5 isala ngentengo ephezulu engu-8,000 yuan/ton. Intengo yomkhiqizo Intengo yezinto ezingavuthiwe izikhathi eziyi-1.5. Phenya izizathu zokwehla: 1. Ukwandisa ukukhiqizwa kwe-rosin ngo-2011. 2. Inkinga yezikweletu zaseYurophu. I-Export ithatha indawo ehamba phambili yokuthengisa ye-rosin. Ukuthunyelwa kwaminyaka yonke kwe-rosin ne-rosin resin emazweni athuthukile eYurophu naseMelika kufinyelela kumathani angaba ngu-370,000. Isikweletu saseYurophu siholela ngokuqondile ekwehleni okukhulu kwe-rosin ethunyelwa eYurophu nase-United States.
Ngokwengqikithi yentengo kawoyela yamazwe ngamazwe yamanje, akunakwenzeka ukuthi i-C5 eluhlaza yehle, i-Petroleum Resin ebeka izindleko eziphelele ze-petroleum resin. Uma intengo ye-petroleum resin ingaphansi kuka-11,000 yuan/ton, i-Petroleum Resin ibhizinisi selizolahlekelwa. Okufanayo kuyiqiniso nge-rosin. Ngokwemithombo evela embonini yamahlathi e-Guangdong, izindleko zokukhiqiza i-rosin zifaka: ukuqasha kwesihlahla, ukukhishwa kwe-resin, i-rosin eya ezimpahleni zasefekthri, i-Petroleum Resin kanye nokuphathwa nokulahlekelwa, futhi intengo ye-rosin ingene ngokuphelele enkathini ye-10,000 yuan. Ngamanye amazwi, i-Petroleum Resin uma intengo ye-rosin ingaphansi kwama-yuan ayi-10,000, inkampani izolahlekelwa yimali. Namuhla, ubudlelwano bokushintshwa phakathi kwe-rosin ne-petroleum resin cishe baziwa kakhulu amafekthri amaningi angaphansi komfula, i-Petroleum Resin kanye nezintengo zokuhlinzeka nezidingo zazo zombili zihlobene.
