Piv txwv li, siv tus neeg sawv cev sizing uas muaj nano-silane lossis nano-titanium, thiab thov nws sib xws rau ntawm qhov chaw ntawm cov iav fiber siv txoj kev sol-gel, ib zaj duab xis nanoscale SiO2 yog tsim rau ntawm qhov chaw ntawm cov iav fiber, ua rau nws lub zog thiab kev sib raug zoo ntawm qhov chaw, thiab txhim kho nws lub zog sib txuas nrog cov resin matrix.

2. Kev Tsim Kho Zoo Tshaj Plaws ntawm Cov Qauv Sib Txawv ntawm Cov Khoom Siv Sib Txawv

Los ntawm kev sib koom ua ke ntau yam khoom siv, tus neeg sawv cev ntsuas qhov loj me tuaj yeem tsim cov txheej txheem ua haujlwm sib xyaw rau ntawm qhov chaw ntawm cov iav fiber, ua tau raws li qhov xav tau tshwj xeeb ntawm cov khoom siv sib xyaw ua ke ntawm cov iav fiber hauv ntau qhov chaw siv. Cov neeg sawv cev ntsuas qhov loj me ntau yam tsis tsuas yog txhim kho lub zog sib txuas ntawm cov iav fiber thiab lub matrix tab sis kuj muab rau lawv nrog ntau yam khoom xws li kev tiv thaiv corrosion, tiv thaiv UV, thiab tiv thaiv kev hloov pauv kub. Hauv kev tsim qauv zoo tshaj plaws, cov khoom nrog cov haujlwm tshuaj lom neeg sib txawv feem ntau raug xaiv, thiab cov txiaj ntsig synergistic tau ua tiav los ntawm cov feem pua ​​​​​​tsim nyog. Piv txwv li, kev sib xyaw ntawm bifunctional silane thiab polymer polymers xws li polyurethane thiab epoxy resin tuaj yeem tsim cov qauv sib txuas los ntawm cov tshuaj tiv thaiv thaum lub sijhawm txheej txheem txheej txheem, ua rau muaj kev sib txuas ntawm cov iav fiber thiab lub matrix. Rau cov kev xav tau tshwj xeeb hauv qhov chaw kub uas xav tau kev tiv thaiv kub thiab kev tiv thaiv corrosion, ntau cov khoom siv ceramic nanoparticles uas tiv taus kub lossis cov khoom siv ntsev hlau tiv taus corrosion tuaj yeem ntxiv rau kom txhim kho kev ua tau zoo ntawm cov khoom sib xyaw.

3. Kev Tsim Kho Tshiab thiab Kev Tshwm Sim Tshiab hauv Cov Txheej Txheem Txheej Txheem Sizing Agent Plasma

Cov txheej txheem txheej txheem ntawm cov tshuaj ntsuas qhov ntsuas uas siv plasma pab, ua ib txoj kev siv tshuab hloov kho qhov chaw tshiab, tsim cov txheej txheem sib xws thiab ntom ntom rau ntawm qhov chaw ntawm cov iav fibers los ntawm kev tso cov pa dej lossis cov tshuaj lom neeg uas muaj plasma txhim kho, ua kom zoo dua qhov sib txuas ntawm cov khoom sib txuas ntawm...cov iav fiberthiab lub matrix. Piv nrog rau cov txheej txheem txheej txheem sizing agent ib txwm muaj, cov txheej txheem plasma-pab tau tuaj yeem cuam tshuam nrog cov iav fiber nto los ntawm cov khoom plasma siab zog ntawm qhov kub qis, tshem tawm cov khoom tsis huv ntawm qhov chaw thiab qhia cov pab pawg nquag, txhim kho qhov sib raug zoo thiab kev ruaj khov ntawm cov fibers. Tom qab txheej nrog cov iav fibers kho plasma, tsis yog tsuas yog lub zog sib txuas interfacial tuaj yeem txhim kho ntau heev, tab sis nws kuj tseem tuaj yeem muab cov haujlwm ntxiv xws li hydrolysis tsis kam, UV tsis kam, thiab qhov kub sib txawv tsis kam. Piv txwv li, kho cov iav fiber nto nrog cov txheej txheem plasma qis-kub thiab sib xyaw nrog cov neeg sawv cev organosilicon sizing tuaj yeem tsim cov txheej txheem UV-resistant thiab kub-resistant, txuas ntxiv lub neej kev pabcuam ntawm cov khoom sib xyaw. Cov kev tshawb fawb tau qhia tias lub zog tensile ntawm cov iav fiber composites coated nrog plasma-pab tau tuaj yeem nce ntau dua 25%, thiab lawv cov kev ua haujlwm tiv thaiv kev laus tau txhim kho ntau heev hauv qhov kub thiab txias hloov pauv.

4. Kev Tshawb Fawb Txog Kev Tsim Qauv thiab Kev Npaj Cov Txheej Txheem ntawm Cov Tshuaj Pleev Xim Uas Muaj Kev Ntsuas Zoo

Cov txheej txheem ntsuas qhov ntsuas ntse yog cov txheej txheem uas tuaj yeem teb rau kev hloov pauv hauv ib puag ncig sab nraud, thiab siv dav hauv cov ntaub ntawv ntse, cov sensors, thiab cov ntaub ntawv sib xyaw kho tus kheej. Los ntawm kev tsim cov neeg sawv cev ntsuas nrog kev nkag siab ib puag ncig rau qhov kub thiab txias, av noo, pH, thiab lwm yam, cov iav fibers tuaj yeem hloov kho lawv cov khoom nto hauv qab ntau yam xwm txheej, yog li ua tiav cov haujlwm ntse.
