Asiri na Epoxy na Epoxy

Tun da resin epoxy nasa ne na rukuni na polymer na ruwa, yana buƙatar taimakon magance wakilai, ƙari da launuka masu tsayayya da cunkoso mai tsauri. Among them, nano oxides are often added as pigments and fillers to epoxy resin coatings, and typical representatives are silica(SiO2), titanium dioxide(TiO2), aluminum oxide(Al2O3), zinc oxide(ZnO), and rare earth oxides. Tare da girman su na musamman da tsari, waɗannan Nano ya yi etoesides suna nuna yawancin kayan aikin jiki da na sunadarai, wanda zai iya haɓaka kaddarorin lalata da abubuwan haɗin lalata.

Akwai manyan hanyoyin guda biyu don karuwa Nano don haɓaka haɓakar kariya ta coxy:

Na farko, tare da karami girman, zai iya cika da micro-cracks da pores kafa ta hanyar samar da kafofin watsa labarai na Epoxy, da kuma inganta hanyoyin kariya da kariya da aikin kariya na shafi;

Na biyu shine ayi amfani da babban taurarin oxide don ƙara yawan ƙarfin hatsar epoxy, ta yadda ke haɓaka kayan aikin injin na shafi.

Bugu da kari, ƙara adadin da ya dace na barbashi na Nano na iya ƙara haɓakar Interface ta hanyar haɗin gwiwar epoxy mai kawowa da kuma mika rayuwar sabis na shafi.

Nano SiO2 galibi suna taka rawar anti-lalata a cikin filaye na epoxy shafi. A gefe guda, silicon dioxide na iya cika micro-fasa da pores da aka samar a cikin tsarin cirewar guduro, kuma inganta shigar shigar shigarwar shiga ciki; on the other hand, , The functional groups of nano-SiO2 and epoxy resin can form physical/chemical cross-linking points through adsorption or reaction, and introduce Si—O—Si and Si—O—C bonds into the molecular chain to form a three-dimensional network structure to improve coating adhesion . Bugu da kari, babban Harshen Nano-Sio2 na iya inganta juriya da juriya, da kyau ta tsawaita rayuwar rayuwar sabis na shafi.
