Hauv kev lag luam niaj hnub, kev txhim kho ntawm cov ntaub ntawv sib xyaw feem ntau yog nyob ntawm qhov zoo ntawm kev sib txuas ntawm cov khoom siv inorganic thiab cov organic matrices.Aluminate coupling agents, raws li cov khoom sib xyaw ua ke tsis sib xws, ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv kev hloov pauv vim lawv cov khoom amphiphilic molecular. Lawv ua tau zoo txo qhov nro ntawm lub ntsej muag thiab txhim kho dispersibility thiab kev sib raug zoo los ntawm kev tsim cov txuas ruaj khov molecular ntawm cov muab tub lim thiab cov matrix, yog li txhim kho cov khoom siv kho tshuab, kev ua haujlwm zoo, thiab ua haujlwm ntev ntawm cov khoom sib xyaw.
Aluminate coupling agent molecules yog nyob ib ncig ntawm aluminium atoms, nrog cov polar functional pawg thiab tsis yog -polar ntev-chain alkyl pawg txuas nrog bridging oxygen bonds. Cov polar xaus tuaj yeem tsim kev sib koom ua ke lossis muaj zog hydrogen bonds nrog cov chaw ua haujlwm xws li hydroxyl pawg thiab hlau ions ntawm qhov chaw muab tub lim, ua kom muaj zog anchoring; cov tsis yog-cov saw ntev ntev tau nkag mus tob rau hauv cov organic matrix, entangled thiab sib haum nrog cov ntu polymer, tsim ib tus choj hla ob theem. Cov qauv no ua rau lawv muaj peev xwm sib txuas lus zoo heev thiab kev ua haujlwm dav dav, tso cai rau lawv ua haujlwm ruaj khov hauv ntau lub tshuab xws li yas, roj hmab, thiab txheej.
Hauv kev hloov kho cov yas yas, aluminate coupling cov neeg ua haujlwm tuaj yeem txo qhov muab tub lim agglomeration thiab txhim kho yaj flowability, ua kom cov khoom ua tau zoo dua lub zog thiab toughness thaum tswj tus nqi qis. Hauv kev lag luam roj hmab, lawv tuaj yeem txhim kho qhov tawg ntawm cov khoom siv ntxiv thiab txhim kho kev puas tsuaj thiab tsim kua muag ntawm cov roj hmab vulcanized. Nyob rau hauv coatings thiab inks, lawv muaj peev xwm optimize lub dispersion stability ntawm pigments thiab fillers, thiab txhim khu cov txheej gloss thiab adhesion. Tsis tas li ntawd, lawv cov volatility tsawg, tsis muaj toxicity, thiab zoo thermal stability ua tau raws li qhov yuav tsum tau ntawm ntsuab manufacturing thiab kev nyab xeeb ntau lawm.
Nrog rau qhov kev thov ntau ntxiv rau cov khoom siv sib xyaw ua haujlwm siab, aluminate coupling agents tab tom txhim kho mus rau kev sib xyaw ua ke thiab kev siv dav. Los ntawm kev qhia cov cua sov- tiv taus, roj- tiv taus, lossis nplaim taws- cov pab pawg retardant los ntawm kev tsim qauv molecular, lawv tuaj yeem ua tau raws li cov kev xav tau nruj ntawm cov chaw tawm tshiab xws li lub zog tshiab, hluav taws xob, thiab cov khoom siv siab - kawg. Raws li ib qho tseem ceeb ntxiv rau kev hloov kho interface, aluminate coupling agents yuav txuas ntxiv ua kom muaj txiaj ntsig zoo hauv kev txhim kho cov khoom siv thiab kev txhim kho kev lag luam.
