Gabatarwa ga aikin aikace-aikacen halaye na epoxy gilashin fiber allo

Epoxy gilashin fiber allo, epoxy phenolic laminated gilashin zane allon, epoxy guduro gaba daya yana nufin Organic polymer mahadi dauke da biyu ko fiye epoxy kungiyoyin a cikin kwayoyin, sai dai wasu, danginsu kwayoyin talakawan ba su da girma. Tsarin kwayoyin halitta na resin epoxy yana da alaƙa da ƙungiyar epoxy mai aiki a cikin sarkar kwayoyin halitta. Ƙungiyar epoxy na iya kasancewa a ƙarshe, a tsakiya ko a cikin tsarin tsarin sarkar kwayoyin halitta. Saboda tsarin kwayoyin halitta ya ƙunshi ƙungiyoyin epoxy masu aiki, za su iya fuskantar halayen haɗin kai tare da nau’ikan nau’ikan magunguna daban-daban don samar da polymers marasa narkewa da infusible tare da tsarin hanyar sadarwa ta hanyoyi uku.

Epoxy gilashin fiber allo aikace-aikace halaye da ayyuka:

1. Kayan aikin inji. Tsarin warkar da epoxy resin yana da kyawawan kaddarorin inji.

2. Manne mai ƙarfi. Ƙungiyoyin polar hydroxyl na asali da haɗin ether a cikin sarkar kwayoyin resins na epoxy sun sa ya zama mai mannewa ga abubuwa daban -daban. Rushewar resin epoxy yana da rauni yayin da ake warkewa, kuma damuwar cikin da aka samar tana da ƙanƙanta, wanda kuma yana taimakawa haɓaka ƙarfin adhesion.

3. Magani mai dacewa. Zaɓi wakilai daban -daban na warkarwa, tsarin resin epoxy kusan ana iya warkewa a cikin yanayin zafin jiki na 0 ~ 180 ℃.

4. Sigogi iri -iri. Dabbobi daban -daban, wakilai masu warkarwa, da tsarin canzawa na iya kusan dacewa da buƙatun aikace -aikace daban -daban akan fom, kuma kewayon na iya kasancewa daga ɗan ƙaramin danko zuwa madaurin daskarewa.

5. Ƙananan raguwa. Halin da ke tsakanin resin epoxy da wakilin maganin da ake amfani da shi ana aiwatar da shi ta hanyar tarawa kai tsaye ko raunin buɗe polymerization na ƙungiyoyin epoxy a cikin ƙwayar resin, kuma babu ruwa ko wasu samfura marasa ƙarfi da aka saki. Idan aka kwatanta da sinadarin polyester wanda ba a cika cikawa da resins na phenolic ba, suna nuna raguwa sosai (ƙasa da 2%) yayin warkewa.
