Lankwasawa Test Kuma Manne na FBE foda shafi

Adhesion na FBE foda shafi

Ana amfani da ma'auni mai mahimmanci don ƙayyade mannewa na FBE foda shafi, kuma Fig.7 yana nuna ka'idar gwajin gwaji. Shugaban mai gwada cupping yana da siffar zobe, yana tura baya na bangarori masu rufi don gwada ko ingantaccen fim ɗin ya fashe ko kuma ya rabu da substrate. Fig.8 shine sakamakon gwajin cupping na epoxy foda shafi. Ana iya ganin cewa FBE foda kayan kwalliyar da ba a cika su da CTBN-EP prepolymers suna da ƙananan ɓangarorin bayyane (Fig. 8 (1)), yayin da suturar da aka cika da CTBN-EP prepolymers (Fig. 8 (2-3)) ba su da fashewar gani, yana nuna mannewa mai kyau da tauri.

Juriya ga lankwasawa gwaje-gwaje na FBE foda coatings

Hoton 9 yana nuna juriya ga lankwasawa sakamakon gwajin nau'ikan nau'ikan nau'ikan nau'ikan FBE guda uku. Juriya ga lankwasa FBE foda coatings ba tare da cika tare da CTBN-EP prepolymers ba shi da kyau (Fig.9 (1)), kuma an samu wani abin mamaki gazawar hadin gwiwa. Lokacin da aka ƙara CTBN-EP prepolymers a cikin foda foda, juriya ga lankwasa FBE foda da aka inganta sosai tare da ƙara yawan abun ciki na CTBN-EP prepolymers (Fig.9 (2-3)), kuma babu wani abin da ya faru na gazawar haɗin gwiwa da aka samu. , yana nuna babban juriya ga lankwasawa.

Gwajin fesa gishiri na sutura

Ana ƙididdige juriya na lalacewa ta hanyar fallasa suturar zuwa yanayin hazo na gishiri wanda aka haifar ta hanyar fesa 5wt% mai ruwa NaCl bayani a 35 ± 2 ° C don 3000 h daidai da ISO 14655: 1999 ƙayyadaddun. Bayan cirewa daga ɗakin hazo na gishiri, duk samfuran ana wanke su da ruwa mai narkewa don cire duk wani abin da ya rage, ana lura da lalatawar sutura. Ana iya gani daga Fig.10, bayan an cika suturar da aka cika da CTBNEP prepolymers (Fig.10b), babu wata shaida na tsatsa, kuma samfurori ba su da hutu, suna nuna rashin juriya na suturar da aka yi da CTBN EP prepolymers. zai iya biyan bukatun ma'auni.

Juriya na lalatawar abin da ke tattare da kwayoyin halitta ba tare da lahani ba ya dogara ne akan kaddarorin shingensa, watau, yadda yake rage yaduwar danshi da ions masu lalata ta cikin fim din. Daga cikin sigogin da ke ba da gudummawa ga kaddarorin shinge shine harin da ke ƙarƙashin ƙarfen ƙarfe. Rufin da ke kusa da wurin da ba a sani ba yana haifar da shinge mai wucewa a kan abin da ke hana kara lalata. Don haka, yana iya kama ions (wataƙila Cl-) cikin sauƙi don samar da polymer ɗin da aka ƙera.
