xaashida kululaynta resinka Epoxy
1. Soo bandhigida badeecada Epoxy resin heat xaashida {09} {61919} 082097}
saxan kululaynta resin Epoxy waxa kale oo loo yaqaan saxan kululaynta fiber epoxy galaas, iyo epoxy phenolic laminated galaas saxan kululaynta. Saxanka Epoxy: Maradu waxay ku xidhan tahay resin epoxy waxaana lagu sameeyaa kuleyl iyo cadaadis. Waxay leedahay sifooyin farsamo oo sarreeya heerkulka dhexdhexaadka ah iyo guryaha korantada ee deggan ee qoyaanka sarreeya. Ku habboon qaybaha makaanikada, korantada iyo elektiroonigga leh qaab-dhismeed heer sare ah, oo leh qalab farsamo iyo dielectric sare, caabbinta kulaylka wanaagsan iyo caabbinta qoyaanka. Heerka kulaylka u adkaysta ee F (155 darajo) waxaa u qaabaysan kulayl heerkulkiisu sarreeyo 180℃, dhumucdiisuna tahay 0.5 ~ 100mm.
2. Tilmaamaha ugu muhiimsan ee Epoxy resin warming6 {09} 082097}
(1). Foomam kala duwan Noocyada kala duwan ee resin, wakiilada daweynta iyo hababka wax ka beddelka ayaa ku dhawaad buuxin kara shuruudaha codsiyada kala duwan, oo u dhexeeya mawjadaha aadka u hooseeya ilaa meelaha adag ee dhalaalka sare.
(2). Daawaynta ku habboon. Iyada oo leh walxo daaweyn oo kala duwan, nidaamka resin epoxy waxaa lagu daweyn karaa ku dhawaad heerkulka 0 ~ 180 ℃.
(3). Ku dheggan adag. Jiritaanka hydroxyl polar iyo curaarta ether ee silsiladda molecular ee resin epoxy waxay ka dhigaysaa in ay yeelato adhesion sare oo walxaha kala duwan ah. Yaraynta xabagta epoxy inta lagu jiro daawaynta waa yar tahay culayska guduhuna waa yar yahay, kaas oo sidoo kale waxtar u leh hagaajinta xoogga adhesionka.
(4). Qandaraasyo hoose. Dareen-celinta u dhaxaysa xabagta epoxy-ga iyo wakiilka daawaynta waxa lagu fuliyaa falcelin toos ah oo dheeraad ah ama falcelinta polymerization-ka-furay ee kooxaha epoxy ee ku jira molecules resin-ka, oo aan biyo ama alaab kale oo kacsan la sii dayn. Marka la barbar dhigo xabagta polyester-ka aan dheregsanayn iyo resin phenolic, waxay muujinayaan hoos u dhac aad u hooseeya (in ka yar 2%) inta lagu jiro daawaynta.
(5). Guryaha makaanikada. Nadaamka resin epoxy ee la daweeyay waxa uu leeyahay mechanical properties.ng nolol adeeg oo aad u wanaagsan mana fududa in la da'da
3. Codsiga ugu wayn ee Epoxy resin warming6 {09} 082097}
Xabagta Epoxy ayaa si weyn loogu isticmaalay dahaarka iyo baakadaha qalabka korantada ee korantada sare iyo kuwa hooseeya, matoorada iyo qaybaha elektiroonigga ah sababtoo ah wax qabadkeeda dahaarka sare, xoog dhisme oo xoog leh iyo waxqabadka xidhidhiyaha wanaagsan.
