Titanate coupling agents, raws li qhov tseem ceeb additives rau kev txhim kho lub interfacial compatibility ntawm inorganic fillers thiab organic matrices, ncaj qha cuam tshuam rau cov neeg kho tshuab, thermal, thiab ua cov khoom ntawm composite cov ntaub ntawv. Kev siv cov qauv muab kev qhia kev sib koom ua ke rau txhua theem ntawm kev tsim khoom, tshuaj xyuas, thiab daim ntawv thov, tsim lub hauv paus hauv paus rau kev ua kom cov khoom zoo thiab ua tiav kev hla - kev lag luam kev sib nrig sib paub thiab kev lag luam du.
Cov qauv siv tam sim no feem ntau muab faib ua peb pawg: cov qauv hauv tebchaws, cov qauv kev lag luam, thiab cov qauv hauv pawg. Lub teb chaws cov qauv tsom mus rau kev nyab xeeb dav dav thiab cov cim qhia kev ua tau zoo, xws li cov cai tswj kev nyab xeeb uas cuam tshuam txog kev faib tshuaj lom neeg, kev sau npe, kev thauj mus los, thiab kev khaws cia, nrog rau cov txheej txheem rau kev txiav txim siab cov txheej txheem physicochemical tsis xws li ya raws, ntom, thiab viscosity, tsim kom muaj qhov tsawg kawg nkaus rau kev lag luam tag nrho. Cov qauv kev lag luam tau tsom ntau dua, qhia txog txoj hauv kev los ntsuas cov haujlwm ntawm cov neeg ua haujlwm sib txuas, cov ntsuas kev sib raug zoo, thiab kev pom zoo ntau npaum li cas rau thaj chaw sib txawv xws li yas, roj hmab, thiab txheej txheej, ua kom muaj kev sib raug zoo ntawm cov khoom ua tau zoo thiab qhov kawg - cov neeg siv xav tau. Cov txheej txheem pab pawg feem ntau yog tsim los ntawm kev coj noj coj ua ntawm cov koom haum kev lag luam lossis cov chaw tshawb fawb. Lawv tuaj yeem koom nrog kev txiav-txoj kev ua tiav thev naus laus zis sai, teeb tsa cov kev xav tau siab dua rau cov tshiab chelating, kev sib koom tes, thiab cov neeg ua haujlwm sib txuas, thiab tsav kev lag luam mus rau kev ua haujlwm siab thiab kev loj hlob ntsuab.
Nyob rau hauv cov nqe lus ntawm kev qhia, cov qauv feem ntau npog plaub qhov ntev: zoo li, purity, kev ua, thiab stability. Cov tsos mob yuav tsum muaj xws li cov xim tsis muaj xim rau lub teeb daj pob tshab kua lossis cov tshuaj pleev ib ce, tsis muaj qhov pom tsis zoo thiab txheej txheej. Purity yog constrained los ntawm titanium cov ntsiab lus, ester pab pawg neeg piv, thiab noo noo txwv, nrog ib tug ntau noo noo txwv ntawm tsawg tshaj li los yog sib npaug rau 0.5% los tiv thaiv hydrolytic inactivation. Kev soj ntsuam kev ua haujlwm feem ntau siv cov txheej txheem sedimentation lossis kev ntsuas kev sib txuas ntawm lub zog kom paub tseeb tias cov txheej txheem ntawm cov coupling tus neeg sawv cev ntawm qhov chaw muab tub lim thiab kev txhim kho cov khoom siv ntawm cov khoom sib xyaw. Kev ruaj ntseg qhia txog qhov kev ua tau zoo ntawm kev khaws cia tom qab khaws cia rau qee lub sijhawm nyob rau hauv qhov tshwj xeeb kub thiab av noo, ua kom cov khoom tuav nws txoj haujlwm thoob plaws hauv cov khoom siv thiab kev ua haujlwm.
Cov txheej txheem xeem yog cov kev txhawb nqa tseem ceeb rau kev siv tus qauv. Infrared spectroscopy yog siv los txheeb xyuas cov haujlwm ua haujlwm ntawm cov qauv molecular; Kev tsom xam thermogravimetric txiav txim siab tus cwj pwm thermal decomposition thiab ua kom kub ntau yam; Karl Fischer titration yog siv los txiav txim siab cov ntsiab lus noo noo; thiab kev tsom xam cov ntsiab lus ntsuas qhov feem ntawm titanium thiab lwm yam tseem ceeb. Tus qauv kuj qhia meej meej cov qauv ua ntej, ntsuas ntsuas ntsuas, tus naj npawb ntawm cov kev xeem sib npaug, thiab kev tso cai rau cov txiaj ntsig, kom ntseeg tau qhov sib piv thiab traceability ntawm cov ntaub ntawv xeem.
Daim ntawv thov tus nqi ntawm tus qauv yog xav txog peb yam: ua ntej, nws muab cov lag luam nrog cov hom phiaj tswj kev ua tau zoo rau kev tsim khoom, txo cov kev hloov pauv ntawm batch; thib ob, nws tsim lub hauv paus tsis ncaj ncees rau kev txais yuav tus neeg yuav khoom thiab thib peb -kev ntsuam xyuas lub koom haum ntsuam xyuas, txo cov kev pheej hmoo ntawm kev lag luam; thiab thib peb, nws qhia R & D kev taw qhia, ua rau cov tuam txhab ua kom zoo dua cov txheej txheem synthesis thiab tsim qauv tsim nyob ib ncig ntawm cov qauv ntsuas, yog li txhim kho cov khoom sib tw.
Raws li daim ntawv thov ciam teb ntawm cov ntaub ntawv tshiab txuas ntxiv nthuav dav, tus qauv rau titanate coupling cov neeg sawv cev kuj yuav tsum tau hloov kho tshiab kom suav nrog cov cim tshwm sim xws li ntsuab synthesis, tsis muaj tshuaj lom thiab tsis muaj zog, thiab rov ua dua tshiab kom tau raws li cov kev xav tau ntawm kev tsim kho kom ruaj khov. Nrog rau kev txhim kho tas mus li thiab kev siv nruj ntawm cov txheej txheem kev lag luam, kev lag luam qib zoo thiab daim ntawv thov kev ntseeg siab yuav ruaj khov, pab txhawb kev sib koom ua ke ntawm kev lag luam saw.
