Titanate coupling agents yog ib qho tseem ceeb additives rau kev txhim kho lub interfacial compatibility ntawm inorganic fillers thiab organic matrices. Lawv daim ntawv thov cov nyhuv yog ze ze rau cov ncauj lus kom ntxaws tswj cov txheej txheem siv. Kev tsis saib xyuas cov ntsiab lus tseem ceeb hauv kev xaiv cov khoom siv, khaws cia, ntxiv, thiab kev ua haujlwm tsis yog tsuas yog txo cov kev hloov kho kom zoo, tab sis kuj ua rau muaj kev hloov pauv ntawm kev ua haujlwm thiab txawm tias muaj kev nyab xeeb. Kab lus no qhia txog cov kev ceev faj tseem ceeb rau kev siv los ntawm ntau qhov ntev, muab cov ntaub ntawv siv rau kev ua lag luam.
Ua ntej, kev tswj hwm nruj ntawm kev cia khoom yog qhov tseem ceeb. Cov ester pawg nyob rau hauv titanate coupling cov neeg ua hauj yog heev rhiab heev rau ya raws, yooj yim undergoing hydrolysis thaum sib cuag nrog dej, tsim inactive titanium oxides thiab poob lawv coupling muaj nuj nqi. Yog li ntawd, cov khoom yuav tsum tau muab kaw thiab khaws cia rau hauv qhov chaw txias, qhuav. Qhov zoo tshaj plaws, qhov kub yuav tsum yog 10-25 degree, qhov txheeb ze av noo yuav tsum tsis pub tshaj 40%, thiab nws yuav tsum tau ceev kom deb ntawm qhov chaw tshav kub thiab tshav ntuj ncaj qha. Thaum qhib, nws yuav tsum tau siv sai li sai tau. Txhua yam khoom seem yuav tsum tau muab rov qab nruj nreem kom tiv thaiv kom tsis txhob ya raws.
Qhov thib ob, kev ntsuas kev sib raug zoo ua ntej ntxiv yog qhov tseem ceeb. Cov qib sib txawv ntawm titanate esters sib txawv hauv cov qauv qauv, pab pawg ua haujlwm, thiab qhov kub thiab txias, thiab kev txheeb xyuas kev sib raug zoo nrog cov matrix resin, hom muab tub lim, thiab cov khoom siv yog tsim nyog. Tshwj xeeb, yog tias lub kaw lus muaj cov kua qaub uas muaj zog, cov hauv paus muaj zog, lossis cov neeg ua haujlwm dawb radical uas muaj zog heev, nws tuaj yeem txhawb kev puas tsuaj ntxov ntxov los yog deactivation ntawm titanate ester. Nws qhov kev ruaj ntseg yuav tsum tau tshawb xyuas hauv me me - kev sim ntsuas kom tsis txhob muaj kev cuam tshuam tsis zoo thaum lub sij hawm siv batch.
Thib peb, kev tswj xyuas meej ntawm kev siv tshuaj thiab dispersion yog qhov tseem ceeb. Ntau tus neeg sawv cev sib txuas tsis tas yuav zoo dua; Cov nyiaj ntau dhau tuaj yeem ua rau tus kheej -polymerization ntawm qhov sib cuam tshuam lossis cov tshuaj tiv thaiv ntau dhau nrog cov resin, uas ua rau muaj kev puas tsuaj rau cov khoom sib cais sib cais. Kev noj tshuaj tsis txaus ua rau muaj kev hloov pauv tsis txaus ntawm kev sib tshuam, ua rau nws nyuaj rau kev hloov pauv kev ntxhov siab. Ib qho kev siv dav dav yog 0.5% -3% ntawm qhov muab tub lim, tab sis qhov kev pom zoo yuav tsum tau txiav txim siab sim. Ntxiv rau, cov kuab tshuaj dilution ua raws li kev tshuaj tsuag lossis kua-theem ua ntej-dispersion tuaj yeem siv, ua ke nrog cov khoom siv sib xyaw ua ke siab - nrawm kom ntseeg tau tias cov txheej txheem sib xws. Yog tias tsim nyog, cua sov tuaj yeem siv los txhawb kev taw qhia kev sib dhos ntawm qhov chaw muab tub lim.
Tsis tas li ntawd, cov av noo thiab kub tswj kev ua haujlwm ib puag ncig yog qhov tseem ceeb. Vim tias qhov kev pheej hmoo ntawm hydrolysis nce nrog cov av noo, kev sib xyaw lossis cov txheej txheem extrusion yuav tsum tau ua nyob rau hauv ib qho chaw dehumidified kom ntau li ntau tau, thiab kev ua haujlwm kub yuav tsum tau khaws cia siab tshaj qhov kub ntawm tus neeg sawv cev sib txuas tab sis hauv qab nws cov thermal decomposition kub los tiv thaiv thermal degradation thiab poob ntawm kev ua haujlwm. Rau cov cua sov-sensitive matrices, lub qhov rais ua haujlwm nyab xeeb yuav tsum tau txiav txim siab ua ntej los ntawm kev tsom xam thermal.
Thaum kawg, kev ceev faj txog kev nyab xeeb thiab pov tseg pov tseg yog qhov tseem ceeb heev. Qee cov titanate raw cov ntaub ntawv thiab cov kuab tshuaj ua rau khaus lossis volatile; Cov neeg ua haujlwm yuav tsum hnav hnab looj tes tiv thaiv, tsom iav, thiab lub tshuab ua pa, thiab ua kom muaj cua zoo. Cov kua dej khib nyiab yuav tsum tau sau raws li kev tswj hwm tshuaj lom neeg thiab muab pov tseg los ntawm cov chaw tsim nyog kom tsis txhob muaj kuab paug ib puag ncig.
Hauv cov ntsiab lus, kev siv tau zoo thiab muaj kev nyab xeeb ntawm titanate coupling agents yuav tsum tau kaw - lub voj voog kev tswj hwm uas suav nrog kev khaws cia, kev sib raug zoo, ntau npaum li cas, txheej txheem, thiab kev tiv thaiv. Tsuas yog los ntawm nruj me ntsis ua raws li cov kev ceev faj no tuaj yeem ua rau lawv qhov kev hloov pauv hloov pauv tau zoo, ua kom ntseeg tau tias cov khoom sib xyaw zoo thiab kev ruaj ntseg ntawm cov txheej txheem ntau lawm.
