C5 roj av resin hloov mus rau hauv C5 hydrogenated petroleum resin los ntawm hydrogenation nyob rau hauv palladium bimetallic catalyst. Cov catalyst muaj alumina-titania composite carrier thiab hlau palladium thiab hlau molybdenum los yog hlau tungsten txhawb nqa ntawm cov cab kuj; Petroleum Resin Cov ntsiab lus yog 0.2-0.4% raws li qhov hnyav ntawm catalyst; Petroleum Resin thiab qhov hnyav piv rau hlau palladium hlau molybdenum los yog hlau tungsten yog 1:0.8-2; Cov txheej txheem txheej txheem ntawm C5 roj av resin catalytic hydrogenation yog: cov tshuaj tiv thaiv kub 70-150âº, Petroleum Resin cov tshuaj tiv thaiv Lub siab yog 3-8MPa thiab qhov chaw pub tshaj tawm yog 1-3h-1.
Cov npaj C5 hydrogenated roj av resin muaj ib tug bromine tus nqi ntawm
Nruam alkaline ntxuav txoj kev ntawm C5 roj av resin: nrog rau cov kauj ruam hauv qab no: C5 roj av resin polymerized kua, Petroleum Resin alkaline kua thiab demulsifier yog dhau los ntawm ib tug zoo li qub tov khoom. Kev sib xyaw ua ntej los tsim cov kua sib xyaw, Roj av Resin uas tsis tu ncua nkag mus rau hauv lub tank polymerization rau tag nrho kev sib xyaw thiab decatalysis Thiab cov polymerization raug txiav, los ntawm cov kav dej. Cov khoom ua kua nyob rau hauv lub polymerization termination tank yog forcibly tov, Roj av Resin thiab cov khoom sib xyaw ua kua nkag mus rau hauv lub khob ntim tank. Kev daws teeb meem, Roj av Resin cov roj av resin pub kua tsis tu ncua nkag mus rau cov txheej txheem tom ntej los ntawm sab saum toj ntawm lub hwj, Roj av Resin thiab hauv qab ntawm lub hwj tswj cov slag tawm.
Qhov zoo: Cov txheej txheem pub mis thiab tso tawm tas li hauv cov txheej txheem alkaline ntxuav yog qhov tsim nyog rau kev tswj xyuas kev ruaj ntseg ntawm cov khoom zoo, Roj av Resin zoo tiv thaiv emulsification thiab entraining resin cov khoom ua kua hauv cov kua dej, thiab lwm yam, thiab txo cov khoom siv thiab txuag nqi. Kev ua tau zoo, Petroleum Resin kev lag luam, thiab tsis tshua muaj paug tsis tu ncua alkaline ntxuav txoj kev.
