Hauv kev sib tham nrog cov neeg siv khoom, ib lub ntsiab lus uas tshwm sim los ntawm ib ntus yog seb Hydrogenatedhydrocarbon cobtiag tiag xa cov nqi ntxiv kom pom tseeb nws tus nqi siab dua piv nrog C9 catalyzed hydrocarbon resin. Txij li Hydrogenated
hydrocarbon cobcov xim sib dua thiab feem ntau muaj cov ntxhiab tsw qab, ntau tus neeg xav tias kev them nyiaj ntau dua txhais tau tias tau txais cov resin zoo dua.
Peb qhov kev paub nrog cov nplaum nplaum thiab txheej txheej qhia tau hais tias yam tsis tshua muaj qhov yooj yim. Lub teeb pom kev zoo lossis tsw tsw qab tuaj yeem yog qhov tseem ceeb hauv qee qhov kev siv, tab sis lawv tsis tas yuav txhais ua kev ua tau zoo tag nrho hauv txhua qhov system. Txawm hais tias qhov kev nqis peev ntxiv ua rau kev nkag siab feem ntau nyob ntawm qhov tshwj xeeb polymer matrix, cov kev pabcuam, cov kev xav tau kev laus, thiab qhov kawg cov neeg siv xav tau los ntawm cov khoom tiav.
Lwm qhov kev nkag siab tsis zoo uas peb nquag ntsib yog lub tswv yim tias Hydrogenated hydrocarbon resin tsuas yog hloov ncaj qha rau C9 catalyzed hydrocarbon resin. Hauv kev xyaum, cov ntaub ntawv no tau pom zoo dua los ua haujlwm rau cov khoom sib txawv thiab cov hom phiaj ua haujlwm sib txawv. Hydrogenation yog ib kauj ruam hloov kho uas txhim kho tej yam ntxwv, tab sis nws yuav tsum tsis txhob muab txhais raws li ib tug thoob ntiaj teb kev txawj tej yam ntxiv uas yuav ua rau ib resin superior rau lwm yam nyob rau hauv txhua formulation.
Ib qho yuam kev uas rov tshwm sim dua
Nyob rau theem pib ntawm ntau qhov haujlwm, peb feem ntau pom cov neeg siv khoom xav tias vim tias hydrogenated C9 zoo li huv thiab sib dua ntawm cov xim, nws yuav tsum ua kom zoo dua catalytically polymerized C9 hauv txhua qhov.
Lwm tus mus rau nws los ntawm qhov opposite direction. Txij li thaum catalytically polymerized C9 nqi tsawg dua, lawv xav tias nws yog "paub version" thiab pom tsis muaj laj thawj siv nyiaj ntau dua.
Nyob rau hauv kev xyaum, ob qho tib si views yog oversimplified.Nyob rau hauv ntau formulation teeb meem peb tau daws nrog ntau xyoo, qhov kev sib tw tsis tshua muaj seb cov resin nws tus kheej yog "zoo txaus." Ntau zaus, cov lus nug tiag tiag yog nyob ntawm cov xim ruaj khov, kev tswj cov ntxhiab, thiab seb cov khoom coj li cas tom qab raug tshav kub, oxygen, los yog qhov chaw cia.
Qee daim ntawv thov muaj kev nkag siab zoo rau cov xwm txheej no. Lwm tus tsis yog. Txawm hais tias qhov sib txawv no tseem ceeb nyob ntawm qhov yuav tsum tau ua ntawm qhov kawg -siv system.
Ob yam khoom no tsis muaj nyob rau tib theem ntawm kev tsim khoom
C9 catalyzed hydrocarbon resin yog tsim los ntawm cationic polymerization ntawm tawg C9 aromatic feem uas muaj cov khoom xws li styrene, methyl styrene, indene, thiab lwm yam aromatic compounds nyob rau hauv Lewis acid catalysts.
Nws cov yam ntxwv feem ntau yog los ntawm nws cov qauv molecular. Cov resin khaws cov aromaticity siab heev, qhia tau zoo heev compatibility nrog ntau nonpolar systems, thiab muab txhim khu kev qha tackifying kev ua tau zoo. Qhov no piav qhia vim li cas nws thiaj li tau siv ua tiav hauv suav tsis txheeb formulations rau ntau xyoo lawm.
C9 hydrogenatedroj av resinTxawm li cas los xij, tsis yog ib txoj hauv kev sib cais polymerization. Nws pib nrog lub hauv paus resin uas twb muaj lawm - ua los ntawm catalytic polymerization los yog thermal polymerization - thiab muab nws rau hydrogenation. Thaum cov txheej txheem no, unsaturated bonds thiab chromophoric qauv yog saturated siv catalysts raws li npib tsib xee, palladium, los yog cov hlau zoo sib xws.
Qhov tseem ceeb, ib lub thev naus laus zis tsim cov resin, thaum lwm qhov hloov kho cov resin tom qab nws tau tsim lawm.Saib ntawm qhov kev xav, lawv tsis sib tw thev naus laus zis txhua.
Feem ntau ntawm qhov sib txawv tshwm sim nyob rau hauv hnub- mus rau -Hnub Kev Ua Tau Zoo dua li kev hloov pauv yam khoom
Hauv kev siv cov tswv yim, qhov sib txawv ntawm catalytically polymerized C9 thiab hydrogenated C9 tsis tshua txhais mus rau qhov sib txawv ntawm kev ua tau zoo. Hloov chaw, lawv zoo li tshwm sim nyob rau hauv ntev - tus cwj pwm coj.
