Tilmaamaha codsiga ee tube fiber galaas epoxy:
Tuubada fiber galaas ee epoxy waxay ka samaysan tahay maro fiber galaas koronto ah oo bilaa alkali ah oo lagu shubay xabagta epoxy, waana la dubay oo lagu cadaadiyaa qaab caaryar ah. Usha wareegsan waxay leedahay shaqo farsamo oo sarreeya. Shaqada dielectric iyo mashiinada wanaagsan. Waxa loo isticmaali karaa sidii qaybo qaab-dhismeed dahaadhaysa qalabka korantada, deegaanka qoyan iyo saliidda beddelka.
Muuqaalka tuubada fiber-ka galaas ee Epoxy: Dusha sare waa inay ahaato mid siman oo siman, oo aan lahayn xumbo, saliid iyo wasakh. Midabka aan sinnayn, xagashada, sinnaansho la’aanta yar iyo dildilaaca ayaa loo oggol yahay dusha dhamaadka ama qayb ka mid ah tuubada fiber-ka galaaska epoxy oo dhumucdeedu ka badan tahay 3mm.
Tilmaamaha codsiga ee tube fiber galaas epoxy:
1. Noocyo kala duwan. Resins kala duwan, wakiilada daweynta iyo hababka wax ka beddelka ayaa ku dhawaad buuxin kara shuruudaha codsiyada kala duwan, miisaankooduna wuxuu u dhexeeyaa mawjadaha aadka u hooseeya ilaa meelaha adag ee dhalaalka sare.
2. Daawaynta ku habboon. Adigoo isticmaalaya dawooyin kala duwan, nidaamka resin epoxy waxa lagu daweyn karaa heerkul u dhexeeya 0 ilaa 180°C.
3. adhesion xoog leh. Waxaa jira kooxo hydroxyl polar iyo curaarta ether ee silsiladda molecular ee resin epoxy, taas oo ka dhigaysa in ay leedahay adhesion sare ee walxaha kala duwan. Xabagta Epoxy waxay leedahay gaabin hoose iyo walbahaarka gudaha inta lagu jiro daaweynta, kaas oo sidoo kale gacan ka geysta hagaajinta xoogga isku xirnaanta.
4. Gaabin hoose. Dareen-celinta u dhaxaysa xabagta epoxy-ga iyo wakiilka daaweynta waxa lagu fuliyaa fal-celin toos ah oo isku-dar ah ama polymerization-ka-furan ee epoxide ee molecule resin-ka, iyada oo aan lahayn biyo ama alaab kale oo kacsan. Marka la barbar dhigo resins polyester-ka aan dheregsanayn iyo resins phenolic, waxay muujinayaan gaabin aad u hooseeya (in ka yar 2%).
5. Shaqada makaanikada. Nidaamka epoxy ee la daweeyay wuxuu leeyahay shaqooyin farsamo oo aad u fiican.
