Uphuhliso loshishino lwepetrochemical lubonelela ngezinto ezityebileyo nezingabizi kakhulu zokwenziwa kweresin yepetroleum. Ke ngoko, imveliso yepetroleum resin kwamanye amazwe aphuhlileyo epetrochemical iphuhliswe ngokukhawuleza, iPetroleum Resin efana neUnited States, Japan, Germany, Russia, France, Petroleum Resin Britain.
Okwangoku, iipeyinti zokumakisha zendlela zangaphandle zisekelwe emanzini kwaye ziphuhliswa ngokukhawuleza. Ngaphezulu kwe-90% yeepeyinti zophawu lwendlela kumazwe aphuhlileyo anjenge-United States, iJamani, iSpain, iSweden, neFinland asebenzisa iimveliso ezisekwe emanzini. Ngenxa yokuqalisa kwangethuba kweendlela zokumakisha zendlela yangaphandle kunye nophuhliso olukhawulezayo lwetekhnoloji, i-nanometer yokumakisha indlela yokumakisha, iicandelwana ezimbini zokumakishwa kwendlela yokumakisha, i-pigment-coated-coated yendlela yokumakisha, njalo njalo.
I-rosin glycerol resin yimveliso ye-esterification ye-rosin kunye ne-glycerol. Yinto eluqilima elubala emva konyango lwevacuum.
Icandelo lokuQala: Ucoceko lwethu oluphezulu lweCalcium Metal Production Line Ngokuqhelekileyo, i-Annual Out Put imalunga ne-1500 yeetoni ngonyaka kwaye ukucoceka kunokufikelela kwi-99.99%
Ukuqhekeka kwe-ethylene C5 iqhezu lolungiso loxinzelelo lwe-atmospheric luthintela i-45-75â isoprene icandelo elityetyisiweyo njengezinto ezikrwada A; Ukuqhekeka kwe-ethylene C5 iqhezu lokulungiswa koxinzelelo lwe-atmospheric i-25-45â isoprene icandelo eliphuculweyo njengezinto ezikrwada B; I-Ethylene cracking C9 fraction is vacuum ilungiswa phantsi kwe-0.08ï½0.095MPa,Petroleum Resin kunye neqhezu elinendawo yokubilisa ye-140ï½180â lithathwa njengemathiriyeli ekrwada C. Ezi zixhobo zintathu zingentla zilungiswe ngu-A, B no-C zilungiswe ngokwe umlinganiselo wobunzima 1:1.5ï½3.0:1.5ï½3.0 C5/C9 petroleum resin polymerization imathiriyeli ekrwada D;
I-C5 petroleum resin iguqulwa ibe yi-C5 hydrogenated petroleum resin nge-hydrogenation phantsi kwe-palladium bimetallic catalyst. I-catalyst iqulethe i-alumina-titania ye-composite carrier kunye ne-palladium yensimbi kunye ne-molybdenum yensimbi okanye i-tungsten yensimbi exhaswa kwi-carrier ye-composite;
