Nyob rau hauv lub tshav pob ntawm tshuaj additives, titanate coupling agents yog cov ntaub ntawv tseem ceeb rau kev txhim kho lub compatibility ntawm inorganic fillers thiab organic polymers. Lawv qhov kev ruaj ntseg zoo ncaj qha cuam tshuam rau kev ua haujlwm ntawm cov ntaub ntawv sib xyaw. Tsim kom muaj cov txheej txheem kev tshawb fawb thiab cov qauv kev sim yog ib qho tseem ceeb ua ntej kom ntseeg tau tias cov khoom ua tau raws li cov txheej txheem thiab cov qauv kev lag luam.
Cov txheej txheem kuaj pib nrog kev kuaj ua ntej. Cov qauv yuav tsum tau sau raws li lub hauv paus ntsiab lus ntawm tus neeg sawv cev, thiab tom qab ntawd hauv av thiab sieved (feem ntau yog 200 mesh) kom ntseeg tau tias qhov sib txawv ntawm qhov loj me thiab zam cov ntaub ntawv sib txawv vim qhov tsis sib xws. Kev tshuaj xyuas qhov muag yog tom qab ntawd ua kom pom seb cov qauv xim thiab morphology puas zoo ib yam, thiab ua ntej tshuaj ntsuam rau pom tseeb impurities lossis teeb meem agglomeration.
Qhov ntsuas qhov ntsuas tseem ceeb suav nrog ob qhov loj me: tshuaj lom neeg muaj pes tsawg leeg thiab lub cev muaj zog. Hauv kev tshuaj xyuas tshuaj, infrared spectroscopy tuaj yeem tshawb xyuas sai thiab zoo txheeb xyuas cov qauv kev ua haujlwm thiab txheeb xyuas cov yam ntxwv ntawm qhov siab ntawm titanate esters (xws li Ti-O-C bonds); Elemental tsom xam ntsuas cov khoom purity los ntawm kev ntsuas qhov tseem ceeb tsis xws li titanium cov ntsiab lus thiab ester pawg piv. Kev ntsuas kev ua haujlwm ntawm lub cev yog tsom rau cov viscosity, ntom ntom, thiab cov dej noo: viscosity yog ntsuas los ntawm kev hloov viscometer ntawm qhov kub thiab txias (xws li 25 degree) los cuam tshuam lub cev fluidity; Kev tshawb nrhiav dej noo feem ntau siv Karl Fischer txoj kev, tab sis vim muaj peev xwm rau hydrolysis thiab tsis ua haujlwm txawm tias muaj cov kab dej noo, qhov pib yuav tsum tau tswj nruj me ntsis (feem ntau tsawg dua lossis sib npaug li 0.5%).
Functional validation yog ib qho tseem ceeb txuas ntxiv ntawm cov txheej txheem xeem. Los ntawm kev ntsuas coupling efficiency (xws li, sedimentation txoj kev los ntsuam xyuas muab tub lim dispersibility), thermal stability (thermogravimetric tsom xam los soj ntsuam qhov decomposition kub), thiab huab cua tsis kam (kev ntsuam xyuas aging), tiag tiag- ntiaj teb daim ntawv thov scenarios yog simulated kom paub meej tias cov khoom sib koom ua haujlwm hauv cov txheej txheem sib xyaw. Piv txwv li, kev tsom xam thermogravimetric tuaj yeem nthuav tawm tus cwj pwm decomposition ntawm titanate esters ntawm qhov kub thiab txias, muab cov ntaub ntawv txhawb nqa rau kev ua cov qhov rais kub.
Kev ua cov ntaub ntawv thiab kev txiav txim siab yuav tsum ua raws li cov qauv kev qhia tshwj xeeb. Tag nrho cov txiaj ntsig kev xeem yuav tsum raug lees paub los ntawm kev sim sib npaug (feem ntau peb zaug), thiab qhov sib txawv ntawm tus txheeb ze (tsawg dua lossis sib npaug li 5% yog suav tias siv tau) yuav tsum suav. Cov txiaj ntsig tau muab piv nrog cov qauv kev lag luam (piv txwv li, HG / T 2567) lossis cov neeg siv khoom tsim nyog los txiav txim siab batch ua raws. Cov ntaub ntawv ntsuam xyuas yuav tsum tau sau cov ntaub ntawv coj mus kuaj, txheej txheem txheej txheem, cov ntaub ntawv, thiab cov lus xaus kom paub meej txog kev taug qab.
Cov txheej txheem kuaj rau titanate coupling agents ua raws li cov ntsiab lus tseem ceeb ntawm "precise characterization - functional verification - standard judgment". Los ntawm ntau yam -siv kev tsom xam, nws pom zoo cov khoom lag luam zoo, pab cov tuam txhab txhim kho cov txheej txheem, thiab tsim kom muaj lub hauv paus ruaj khov rau kev ua haujlwm ruaj khov rau cov kev siv qis qis, yog li txhawb kev sib koom tes ntawm kev lag luam saw.
