Ukuthuthukiswa kwemboni ye-petrochemical kunikeza izinto zokusetshenziswa ezicebile nezishibhile zokukhiqizwa kwe-petroleum resin. Ngakho-ke, ukukhiqizwa kwe-petroleum resin kwamanye amazwe athuthukile kaphethiloli kuye kwathuthuka ngokushesha, i-Petroleum Resin efana ne-United States, Japan, Germany, Russia, France, Petroleum Resin Britain.
Njengamanje, opende bokumaka bemigwaqo bangaphandle basekelwe emanzini futhi bathuthuka ngokushesha. Bangaphezu kuka-90% opende abamaka bemigwaqo emazweni athuthukile njenge-United States, Germany, Spain, Sweden, neFinland basebenzisa imikhiqizo esekwe emanzini. Ngenxa yokuqalwa kwangaphambi kwesikhathi kwezingubo zokumaka emigwaqweni yangaphandle kanye nokuthuthuka ngokushesha kobuchwepheshe, kuye kwavela ukugqama komgwaqo we-nanometer, izingxenye ezimbili zokugqoka zokumaka umgwaqo, izigqoko zokumaka zomgwaqo ezine-pigment, nokunye.
I-rosin glycerol resin iwumkhiqizo we-esterification we-rosin nge-glycerol. Iqinile ekhanyelayo engajwayelekile ngemva kokwelashwa kwe-vacuum.
Ingxenye Yokuqala: Ulayini Wethu Wokukhiqiza Insimbi Yensimbi Ye-Calcium Ngokujwayelekile I-Annual Out Put icishe ibe ngamathani ayi-1500 ngonyaka futhi ubumsulwa bungafinyelela ku-99.99%
Ukuqhekeka kwe-ethylene C5 ingxenye yokulungiswa kwengcindezi yasemkhathini ihlangana nengxenye engu-45-75â isoprene ethuthukisiwe njengempahla eluhlaza A; i-ethylene cracking C5 ingxenyenamba yokulungiswa kwengcindezi yasemkhathini ihlanganisa 25-45â isakhi esinothisiwe ye-isoprene njengempahla eluhlaza B; Ingxenye ye-Ethylene eqhekeka i-C9 ivacuum elungiswa ngaphansi kuka-0.08ï½0.095MPa,Petroleum Resin futhi ingxenyenamba enephuzu elibilayo elingu-140ï½180â ithathwa njengento eluhlaza C. Izinto zokusetshenziswa ezingenhla ezintathu A, B kanye no-C zilungiswa ngokuvumelana isilinganiso sesisindo esingu-1:1.5ï½3.0:1.5ï½3.0 C5/C9 petroleum resin polymerization impahla eluhlaza D;
I-C5 petroleum resin iguqulwa ibe yi-C5 hydrogenated petroleum resin nge-hydrogenation ngaphansi kwe-palladium bimetallic catalyst. I-catalyst iqukethe isithwali esiyinhlanganisela ye-alumina-titania kanye ne-palladium yensimbi ne-molybdenum yensimbi noma i-tungsten yensimbi esekelwe kusithwali esiyinhlanganisela;I-Petroleum Resin Okuqukethwe ngu-0.2-0.4% ngokusekelwe esisindweni se-catalyst;
