Titanate coupling agents ua lub luag haujlwm tseem ceeb hauv kev hloov pauv hauv kev sib txuas hauv cov ntaub ntawv sib xyaw, thiab lawv qhov zoo cuam tshuam ncaj qha rau cov khoom lag luam thiab cov txheej txheem kev ruaj ntseg. Vim muaj ntau hom qauv thiab cov khoom cuav ntawm lub khw, tsim kom muaj kev tshawb fawb thiab kev txheeb xyuas cov txheej txheem yog ib kauj ruam tsim nyog rau cov tuam txhab, cov koom haum soj ntsuam zoo, thiab cov neeg siv kawg kom paub meej txog kev yuav khoom thiab siv kom raug.
Kev txiav txim ua ntej raws li qhov tshwm sim thiab lub cev muaj zog yog txoj kev qhia ncaj qha tshaj plaws. Cov khoom sib txuas tiag tiag titanate feem ntau tsis muaj xim rau lub teeb daj pob tshab kua lossis qis -viscosity pastes, tsis muaj teeb meem tshem tawm lossis cov khoom tsis huv, thiab muaj xim zoo ib yam. Yog tias turbidity, txheej txheej, nag lossis daus tshwm, nws yuav muaj hydrolyzed thiab deteriorated los yog ua rau cov khoom tsis zoo. Tib lub sijhawm, qhov ceev thiab viscosity tuaj yeem ntsuas rau kev txiav txim siab. Qhov ntom ntawm cov qauv sib txawv ntawm titanates ntawm 25℃feem ntau yog nyob nruab nrab ntawm 0.95 thiab 1.10 g / cm³, thiab cov viscosity txawv ntawm kaum mus rau pua pua millipascals ib ob nyob ntawm qhov hnyav molecular. Qhov txawv txav tseem ceeb los ntawm tus nqi nominal yuav tsum ua rau muaj kev xav tsis thoob.
Kev txheeb xyuas cov qauv tshuaj yog cov kauj ruam tseem ceeb hauv kev lees paub qhov tseeb. Fourier transform infrared spectroscopy (FTIR) tuaj yeem txheeb xyuas cov yam ntxwv ua haujlwm tau sai: cov khoom tiag qhia O-H stretching vibrations (vim yog hydroxyl pawg ntawm cov muab tub lim) nyob ib ncig ntawm 3400 cm⁻¹, C=O stretching peaks nyob rau hauv 1600–1700 cm⁻¹ cov yam ntxwv ntawm absorption, Ti-O-C daim ntawv cog lus nyob rau hauv 1100–1200 cm⁻¹, thiab Ti-O-Ti lossis Ti-O-R teeb liab hauv 750–850 cm⁻¹. Yog hais tias lub spectrum tsis muaj qhov tseem ceeb peaks los yog qhia qhov txawv txav peaks, nws yuav qhia tau hais tias cov khoom cuav los yog decomposition khoom. Nuclear magnetic resonance (¹H-NMR, ¹³C-NMR) tuaj yeem daws cov qauv saw organic ntxiv thiab txheeb xyuas qhov ncaj ncees ntawm pawg ester thiab cov pab pawg ua haujlwm ntawm lub davhlau ya nyob twg.
Elemental tsom xam yog ib txoj hauv kev zoo ntawm kev ntsuas purity. Cov ntsiab lus titanium tuaj yeem txiav txim siab los ntawm X-ray fluorescence (XRF) lossis inductively coupled plasma optical emission spectroscopy (ICP-OES), thiab ua ke nrog kev suav ntawm ester pawg C-H piv, los txiav txim seb lub ntsiab lus puas haum rau cov qauv nominal. Rau cov dej noo, Karl Fischer titration yog pom zoo; siab- cov khoom lag luam zoo yuav tsum muaj cov dej noo qis dua 0.5%, thiab cov qauv ntau tshaj qhov txwv no feem ntau qhia txog hydrolysis.
Kev txheeb xyuas kev ua haujlwm tuaj yeem txuas ntxiv cov txheej txheem txheeb xyuas mus rau qib kev thov. Paub cov fillers thiab cov qauv tuaj yeem raug kho raws li cov txheej txheem los npaj cov ntawv xeem. Dispersion (sedimentation method or microscopic observation) thiab mechanical properties (tensile and impact strength) tuaj yeem kuaj thiab muab piv nrog cov qauv siv tiag tiag. Yog hais tias lub interfacial bonding quab yuam yog txo qis, nws qhia tau hais tias tsis txaus coupling tus neeg sawv cev ua hauj lwm los yog cov yam ntxwv puas. Thermogravimetric tsom xam (TGA) kuj tuaj yeem pab txiav txim siab: cov khoom tiag decompose ntawm qhov kub thiab txias feem ntau ntawm 200-300℃nyob rau hauv ib qho chaw inert, nthuav tawm ib los yog ob peb kauj ruam zoo li poob phaus; Yog hais tias qhov hnyav hnyav tshwm sim ntawm qhov kub thiab txias los yog ntau theem decomposition tshwm sim, impurities los yog mis deviations yuav tshwm sim.
Batch sib xws yuav tsum tau saib xyuas thaum lub sij hawm kev txheeb xyuas. Los ntawm kev sib piv cov ntsuas saum toj no thoob plaws ntau pawg ntawm cov qauv, qhov sib txawv zais los ntawm kev hloov pauv hauv cov txheej txheem tsim khoom lossis hloov cov khoom siv raw tuaj yeem txheeb xyuas, muab lub hauv paus rau kev tswj xyuas zoo hauv cov khoom siv.
Hauv cov ntsiab lus, kev txheeb xyuas cov titanate coupling agents yuav tsum ua tib zoo xav txog kev tshuaj xyuas qhov muag, kev ntsuas lub cev ntawm lub cev, kev tshuaj xyuas cov qauv, thiab kev ua haujlwm pov thawj. Hla -kev pov thawj hla ntau qhov ntev yog qhov tseem ceeb kom paub qhov txawv ntawm qhov tseeb ntawm cov khoom cuav thiab zoo dua los ntawm cov khoom tsis zoo. Qhov no ntxiv dag zog rau txoj kab kev tiv thaiv zoo hauv kev yuav khoom, kev tswj kom zoo, thiab kev siv, ua kom muaj kev ruaj ntseg ntawm cov ntaub ntawv sib xyaw.
