teb. Muaj ob txoj hauv kev tseem ceeb ntawm kev hloov kho. Ib qho yog kev hloov kho hydrogenation, Roj av Resin uas ntxiv ob daim ntawv cog lus hauv cov roj av resin molecule, Petroleum Resin yog li txhim kho nws cov xim thiab tiv thaiv oxidation stability. Petroleum resins nrog cov khoom tshwj xeeb tuaj yeem npaj tau los ntawm kev ntxiv pawg polar los yog hloov pauv xws li monoolefin rau cov khoom siv raw.
Kev tshem tawm cov catalyst yog qhov txuas tseem ceeb hauv kev sib txuas ntawm cov roj av resins. Tom qab cov tshuaj tiv thaiv polymerization tiav, Petroleum Resin tau txais cov tshuaj polymer tsim nyog. Thawj qhov yog tshem tawm cov catalyst los ntawm polymer. 3. Cov ntsiab lus tshauv yog siab heev, Petroleum Resin uas muaj kev cuam tshuam tseem ceeb ntawm cov khoom resin. Kev ntxuav thiab emulsification ntawm cov kua polymerization thiab nqa dej (acid hauv dej) ua rau lub sijhawm ntev rau cov roj thiab dej txheej, Roj av Resin hnyav corrosion ntawm cov cuab yeej hauv kev ntxuav dej cawv, Petroleum Resin distillation thiab cawv rov qab system, Petroleum Resin thiab cov khoom tsis zoo, uas ua rau kev tsim khoom nyuaj rau kev ua haujlwm ib txwm. Vim Al (OH) 3 yog insoluble nyob rau hauv dej thiab cawv, Roj av Resin nws yog ib qho nyuaj rau tshem tawm nrog dej, thiab nws yog yooj yim adsorbed ntawm cov roj-dej interface, Roj av Resin ua raws li ib tug solid-theem emulsifier, thiaj li hais tias lub interface ntawm cov kua ntxhua (dej theem) thiab cov kua polymerization (roj theem) yog generated. Qhov tshwm sim emulsification tsim W / O emulsion, uas ua rau kev sib cais ntawm cov roj thiab dej nyuaj. Tsis tas li ntawd, Petroleum Resin C5 petroleum resin muaj adhesion zoo. Thaum cov tshuaj tiv thaiv zoo li xaus, Petroleum Resin cov tshuaj polymerization maj mam ua viscous. Thaum lub kaw lus ntxuav thiab nplawm, emulsification kuj yooj yim tshwm sim.
Kev daws: Ntxiv ntau NaOH rau qhov teeb meem emulsification. Tus yuam sij rau kev daws qhov teeb meem yog daws qhov teeb meem ntawm emulsification (los yog cov tshuaj polymerization nrog dej), Petroleum Resin uas tuaj yeem hloov dej-insoluble Al (OH) 3 rau hauv dej-soluble sodium aluminate lossis sodium metaaluminate. Hauv kev ua haujlwm tiag tiag, NaOH yog tsim rau hauv 2% mus rau 4% aqueous tov, Petroleum Resin thiab NaOH yog ob npaug ntawm AlCl3. Nyob rau hauv txoj kev no, Petroleum Resin tuaj yeem ua kom ntseeg tau tias AlCl3 tau hloov pauv tag nrho rau hauv cov khoom siv hauv dej thiab tshem tawm yooj yim.
Rau qhov teeb meem ntawm kev tshem tawm catalyst, ntxiv demulsifier kom tshem tawm tag nrho cov catalyst, Petroleum Resin lossis cov catalyst siv cov kua compound AlCl3 kuj tuaj yeem tshem tawm cov catalyst zoo.
