Dab tsi yog kev siv cov khoom ntxiv hauv kev tsim cov epoxy iav fiber ntau kav
Dab tsi yog kev siv cov additives nyob rau hauv zus tau tej cov epoxy iav fiber ntau kav dej
Nws yog ib qho tsim nyog yuav tau ntxiv qee cov tshuaj ntxiv thaum tsim cov epoxy iav fiber ntau kav. Rau cov khoom siv ntxiv no, ntau tus neeg siv khoom thiab cov phooj ywg txhawj xeeb txog seb nws puas yuav cuam tshuam rau kev noj qab haus huv ntawm cov neeg siv. Thiab qhov no xav kom peb paub seb qhov twg yog kev siv cov khoom siv ntxiv hauv kev tsim cov epoxy iav fiber ntau kav. Tam sim no, cia peb saib cov kev taw qhia ntawm kev manufacturers.
Cov additives ntawm epoxy iav fiber yeeb nkab txiav txim siab nws cov kev ua tau zoo heev. Epoxy resin yeeb nkab muaj rigidity zoo heev vim tias nws muaj cov khoom siv kho tshuab zoo heev thiab nyuaj li cov hlau. Kev ua siab ntev muaj qhov ua tau zoo thiab ua tau zoo. Tau kawg, epoxy iav fiber ntau raj kuj tuaj yeem tiv taus qhov cuam tshuam. Lwm qhov taw qhia yog tias qhov nkag tsis kam ntawm epoxy iav fiber ntau raj yog qhov zoo tshaj plaws ntawm cov ntaub ntawv ruaj ntseg. Epoxy iav fiber ntau raj sib txuas ua ke ntau txoj hauv kev, kho kom yooj yim, muaj zog adhesion, tsis tshua muaj shrinkage, thiab muaj kev lag luam dav hauv cov khoom siv hluav taws xob zoo xws li tshuab, khoom siv hluav taws xob, thiab khoom siv hluav taws xob.
Tau kawg, cov no yog cov khoom tseem ceeb heev rau epoxy iav fiber ntau kav. Lub ntsiab tivthaiv ntawm epoxy iav fiber ntau raj yog epoxy resin, uas yog ib tug insulating board laminated nrog iav ntaub thiab epoxy resin. Thaum txiav txim siab txog kev ua haujlwm ntawm epoxy iav fiber ntau yeeb nkab, lub luag haujlwm ntawm cov khoom siv ntxiv xws li curing agent, modifier, muab tub lim thiab diluent yog qhov tseem ceeb heev. Vim tias lawv yog cov khoom siv tsis tseem ceeb rau epoxy resins, lawv txiav txim siab seb cov khoom puas tuaj yeem ua pwm thiab kho. Yog tias nws tsis tuaj yeem molded thiab kho, tsis muaj epoxy iav fiber ntau raj.
Los ntawm kev hloov kho ntawm cov khoom siv ntxiv, epoxy iav fiber ntau yeeb nkab tuaj yeem siv rau ntau qhov chaw. Tom qab hloov qhov kev faib ua feem ntawm cov additives, epoxy iav fiber tube tuaj yeem paub qhov sib txawv ntawm cov khib nyiab los ntawm cov viscosity tsawg heev mus rau qhov siab melting point. Nws tuaj yeem kho tau ntawm txhua qhov kub ntawm qhov kub ntawm 0 txog 180 ° C.
Kev siv cov tshuaj ntxiv txhawb kev tiv thaiv ib puag ncig ntawm epoxy resin. Tsis muaj kev tso dej los yog cov khoom evaporative cuam tshuam. Tus nqi shrinkage yog tsawg, thiab qhov kev ntxhov siab sab hauv ntawm kev yaig kuj txo qis, yog li txhim kho lub zog sib txuas ntawm epoxy iav fiber ntau raj. Tau kawg additives kuj muaj tej yam kev mob tshwm sim. epoxy resin nws tus kheej tsis muaj tshuaj lom, tab sis raws li qhov xav tau hloov pauv, hom thiab muaj pes tsawg leeg ntawm cov khoom siv ntxiv, kev ua haujlwm ntawm epoxy resin kuj tseem yuav hloov, yog li epoxy iav fiber ntau raj yog tshuaj lom. Yog li nws xav tau kev saib xyuas. Qhov no yog vim li cas LCP, uas muaj kev hnav zoo heev thiab hnav tsis kam, tau hloov lub raj epoxy iav fiber ntau raws li cov khoom ntim ntawm cov coil thav duab rau qee yam tom qab siv los ua cov khoom ntim sib xyaw ua ke los koom nrog cov khoom ntim siab.
