Cov ntaub ntawv sib xyaw, vim lawv lub teeb yuag, lub zog siab, thiab kev ua haujlwm ntau, tau dhau los ua ib qho ntawm cov ntaub ntawv tseem ceeb rau kev hloov kho tshiab niaj hnub no. Txawm li cas los xij, kev sib raug zoo ntawm interfacial inorganic fillers thiab organic matrices feem ntau txwv tsis pub lawv qhov kev tso tawm thiab loj -scale daim ntawv thov.Aluminate coupling agents, raws li cov chav kawm ntawm interfacial modifiers ua tau zoo, kov yeej qhov teeb meem no los ntawm kev sib txuas ntawm molecular, ua kom pom qhov tsis zoo ntawm daim ntawv thov nqi hauv cov ntaub ntawv sib xyaw.
Los ntawm kev pom kev ua haujlwm, aluminate coupling agents, nyob rau hauv cov khoom siv txhuas atoms, txuas cov polar functional pawg thiab cov uas tsis yog -polar ntev chains los ntawm bridging oxygen bonds, tsim cov qauv amphiphilic molecular. Lawv lub ncov qaumteb qabteb tuaj yeem thauj cov chaw ua haujlwm xws li hydroxyl pawg thiab cov hlau ions nyob rau saum npoo ntawm cov khoom siv tsis zoo, thaum cov ntu tsis yog -cov ntsiab lus polar nkag mus tob rau hauv cov organic matrix, entangled thiab sib haum nrog cov ntu polymer, txo qhov cuam tshuam ntawm lub ntsej muag thiab tshem tawm cov teeb meem ntub dej ntawm ob theem. Qhov no "molecular choj" tsis tsuas yog inhibits muab tub lim aggregation tab sis kuj ntxiv dag zog rau kev sib raug zoo ntawm kev sib raug zoo, tso cai rau kev ntxhov siab kom sib npaug hauv cov txheej txheem sib xyaw, yog li txhim kho cov khoom siv thiab ua haujlwm ntev ntawm cov khoom.
Daim ntawv thov ntawm aluminate coupling agents yog tshwj xeeb tshaj yog paub tab nyob rau hauv lub teb ntawm yas muab tub lim hloov. Noj cov calcium carbonate- puv polypropylene ua piv txwv, ntxiv qhov tsim nyog ntawm tus neeg sawv cev sib txuas ua kom zoo dua qhov sib txawv ntawm qhov sib txawv ntawm ntau dua 40%, nce qhov cuam tshuam ntawm lub zog los ntawm 25%, thiab ua kom cov dej ntws ruaj khov, muaj txiaj ntsig zoo rau kev lag luam mob taw tes ntawm "nce toughness yam tsis tau nce nqi." Hauv kev lag luam roj hmab, nws tuaj yeem ua kom muaj zog ntxiv xws li silica thiab kaolin, nce 300% tensile kev nyuaj siab ntawm vulcanized roj hmab los ntawm 15% -20%, txo kev puas tsuaj los ntawm ntau tshaj 10%, thiab txuas ntxiv kev pab cuam lub neej ntawm log tsheb, ntsaws ruaj ruaj, thiab lwm yam khoom. Tsis tas li ntawd, nyob rau hauv txheej txheej thiab number case systems, aluminate coupling agents optimize pigment thiab muab tub lim dispersion stability, txo cov xim ntab thiab tawg phenomena, nce txheej gloss los ntawm 30%, thiab ua tiav cov txheej txheem adhesion dua.
Nws yog ib qho tsim nyog sau cia tias qhov kev hloov pauv tau zoo thiab ib puag ncig tus phooj ywg ntawm aluminate coupling cov neeg ua haujlwm txuas ntxiv nthuav dav lawv daim ntawv thov ciam teb. Nws tsis tshua muaj volatility thiab tsis muaj toxicity ua raws li cov qauv tsim ntsuab, ua rau nws muaj kev nyab xeeb rau kev siv nyob rau hauv cov chaw rhiab heev xws li cov ntim khoom noj thiab cov khoom ua si menyuam yaus. Nws qhov kev khiav hauj lwm kub ntau (-20℃txog 200 degree) thiab ya raws ua kom ruaj khov nyob rau hauv siab - kub thiab siab - av noo ib puag ncig. Tsis tas li ntawd, kev qhia txog cov cua sov- tiv taus thiab nplaim taws ua haujlwm pab pawg los ntawm cov qauv tsim qauv tso cai rau cov kev daws teeb meem los ua kom tau raws li cov kev xav tau nruj ntawm cov chaw tawm tshiab xws li lub zog tshiab roj teeb encapsulation thiab 5G cov khoom siv casings.
Hauv cov ntsiab lus, aluminate coupling cov neeg ua haujlwm, nrog rau lawv cov haujlwm tseem ceeb ntawm kev hloov pauv hloov pauv, rhuav tshem cov teeb meem kev ua haujlwm ntawm inorganic fillers thiab organic matrices. Lawv ua lub luag haujlwm tseem ceeb hauv kev txhim kho tag nrho kev ua tau zoo ntawm cov ntaub ntawv sib xyaw, txo cov nqi tsim khoom, thiab txhawb kev tsim ntsuab, ua rau lawv muaj qhov tseem ceeb ntawm cov khoom siv ntxiv hauv cov khoom siv niaj hnub siv tshuab.
