Vim li cas CTI tus nqi ntawm epoxy qis dua SMC?

CTI tus nqi ntawm cov ntaub ntawv epoxy feem ntau qis dua li ntawm SMC, feem ntau yog vim qhov sib txawv ntawm hom matrix resin, formulation system, muab tub lim, thiab molding txheej txheem, uas ua rau muaj qhov sib txawv ntawm qhov sib txawv ntawm cov dej thiab kab.

1, Cov ntsiab lus tseem ceeb

-Qhov txawv ntawm cov matrix resin: Epoxy feem ntau yog bisphenol A hom, thiab benzene nplhaib qauv yog nquag carbonization nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb thiab tshav kub, tsim cov conductive raws. CTI feem ntau yog 400-600V; SMC feem ntau siv unsaturated polyester/vinyl ester, thiab cov saw molecular muaj ester bonds thiab benzene rings. Tom qab cov qauv kev ua kom zoo, lub peev xwm los tiv thaiv carbonization muaj zog dua, thiab CTI tuaj yeem ncav cuag Ntau dua lossis sib npaug li 600V.
-Formula thiab muab tub lim: Epoxy systems feem ntau muaj accelerators, diluents, thiab lwm yam, uas tuaj yeem yooj yim txo qhov chaw tiv thaiv hluav taws xob; SMC muaj feem ntau ntawm cov iav fibers (40% -60%) thiab cov tshuaj tiv thaiv to (xws li txhuas hydroxide thiab silicon dioxide), tsim cov txheej txheej tuab los tiv thaiv cov pa roj carbonization.
-Moulding thiab deg mob: Epoxy casting / lamination yog qhov ua rau muaj qhov tsis xws luag thiab kev ntxhov siab sab hauv, thiab qhov saum npoo yog feem ntau ua rau fouling thiab tawm; SMC compression molding yog ntom, nrog rau qhov sib xws, ruaj khov microstructure, thiab muaj zog tiv thaiv cov kab hluav taws xob.
-Interface thiab impurity tswj: Lub interface bonding thiab impurity tswj ntawm epoxy system yog ib qho nyuaj, thiab lub zos hluav taws xob teb concentration yuav yooj yim ua rau cim; SMC txhim kho cov iav fiber ntau resin interface los ntawm cov neeg ua haujlwm sib txuas, txo qhov cuam tshuam ntawm kev sib txuas, thiab txo qis kev pheej hmoo ntawm hluav taws xob to.

2, Cov ntsiab lus tseem ceeb thiab cov lus pom zoo xaiv

-Cov epoxy CTI feem ntau yog siv ntawm 200-400V, thaum hloov kho epoxy tuaj yeem ncav cuag ntau dua lossis sib npaug li 600V; SMC feem ntau loj dua lossis sib npaug rau 600V.
-Cov txheej txheem xaiv: Siab CTI SMC yog qhov zoo dua rau qhov siab -siab / siab muaj kuab paug; High precision / qis shrinkage hloov kho epoxy yog yuav tsum tau (xws li ntxiv los tiv thaiv cov fillers thiab optimizing curing systems).
