Titanate Coupler|TCA-IAM

Kev faib tawm thiab kev ua haujlwm ntawm coupling agents Coupling agents tuaj yeem txhim kho cov yam ntxwv ntawm kev sib txuas ntawm cov khoom siv polymer thiab cov muab tub lim. Lawv yog ib hom khoom uas muaj cov qauv amphoteric. Qee pawg hauv lawv cov molecules tuaj yeem hnov ​​​​mob nrog cov tshuaj lom neeg nyob rau saum npoo ntawm cov tshuaj inorganic los tsim cov tshuaj lom neeg muaj zog, thaum lwm pab pawg muaj cov khoom siv organophilic thiab tuaj yeem hnov ​​​​mob nrog cov organic molecules los yog lub cev entangle, yog li ruaj khov ua ke ob qho khoom sib txawv. Qhov no tso cai rau cov tshuaj inorganic uas tau siv dav, pheej yig lossis muaj cov khoom tshwj xeeb los siv los ua cov khoom siv los yog cov khoom siv ntxiv hauv cov yas, uas tuaj yeem tsis tsuas yog txo tus nqi ntawm cov yas, tab sis kuj muab lwm yam khoom muaj txiaj ntsig rau cov khoom, xws li kev txhim kho cov khoom siv kho tshuab. , khoom seem stability, thiab lwm yam., expanding Application range of plastics. Muaj ntau ntau hom kev sib txuas, thiab feem ntau siv xws li titanate, aluminate, silanes thiab lwm yam. (1) Lub titanate coupling tus neeg sawv cev molecule muaj ib pawg alkoxy thiab peb cov saw ntev molecular structural units. Thaum tus neeg sawv cev coupling cuam tshuam nrog cov hmoov muab tub lim, pawg alkoxy tshem tawm cov protons ntawm qhov chaw muab tub lim. Cov protons pib los ntawm qhov muab tub lim. Cov dej khi rau hauv cov muab tub lim muaj xws li cov dej siv lead ua, cov dej tshuaj adsorbed thiab lub cev adsorbed dej, tsim cov tshuaj tiv thaiv thiab npog lub ntsej muag ntawm cov muab tub lim nrog ib txheej molecular ntawm coupling tus neeg sawv cev. Peb qhov ntev-chain molecular structural units nyob rau lwm qhov kawg ntawm tus neeg sawv cev coupling muaj peev xwm chemically cross-links los yog lub cev entangle nrog cov polymer molecules, thaum kawg muab cov inorganic muab tub lim thiab cov polymer los txhim kho lub tensile zog thiab elongation ntawm cov khoom. tus nqi thiab cuam tshuam lub zog. Nyob rau tib lub sijhawm, tus neeg sawv cev sib txuas ua rau txo qis lub zog ntawm qhov chaw muab tub lim, txhim kho qhov muaj peev xwm tawg ntawm cov muab tub lim hauv cov resin, txo cov viscosity ntawm lub filling system, ua kom cov filling ntau, txo cov neeg siv khoom hnav, txuag hluav taws xob, thiab txo cov viscosity. tus nqi. . (2) Silane coupling tus neeg sawv cev yog tus neeg sawv cev siv dav tshaj plaws. Nws cov qauv qauv dav dav yog Rsix3. R yog ib pab pawg ua haujlwm zoo uas muaj kev sib raug zoo lossis kev ua haujlwm nrog cov khoom siv polymer, xws li amino, mercapto, vinyl, thiab epoxy. pawg, cyano pawg, pawg methacryloxy, thiab lwm yam., x yog ib pawg alkoxy uas tuaj yeem hydrolyzed. Thaum siv los ua tus neeg sawv cev sib txuas, pawg x yog thawj zaug hydrolyzed los ua silanol, thiab tom qab ntawd rov ua haujlwm nrog pawg hydroxyl ntawm qhov chaw muab tub lim. (3) Txij li thaum feem ntau cov khoom ntawm silane coupling agents thiab titanate coupling agents yog kua, nws coj teeb meem ntxiv rau lawv nyob rau hauv high mixers. Cov xim ntawm cov khoom no tseem yuav cuam tshuam rau kev sau cov hloov kho masterbatch. Yog li ntawd, aluminium Acid ester coupling tus neeg saib xyuas thiab ib hom tshiab ntawm cov khoom sib txuas sib txuas uas yog lub teeb dawb nyob rau hauv daim ntawv ntawm cov khoom siv quav ciab. Vim tias cov khoom siv wax yog ib qho yooj yim rau 'meter' thiab ntxiv, yooj yim rau siv, thiab muaj lub teeb dawb xim, nws tau txais kev pom zoo los ntawm cov tuam ntxhab ntawm inorganic hmoov hloov cov ntaub ntawv xws li calcium carbonate. .
