Qallooca Tijaabada Iyo Ku-xidhka dahaarka budada FBE

Adhesion ee Dahaarka budada FBE

Tijaabada koobabka ayaa inta badan loo isticmaalaa si loo go'aamiyo ku-xidhka dahaarka budada FBE, iyo Fig.7 waxay muujinaysaa mabda'a tijaabada ah ee tijaabiyaha koobabka. Madaxa tijaabiyaha koobabka ayaa ah mid wareegsan, isaga oo riixaya dhabarka muraayadaha dahaarka leh si loo tijaabiyo in filimka togan uu dillaacay ama ka go'ay substrate-ka. Sawirka 8 waa natiijada tijaabada koobabka ee daahan budada epoxy. Waxaa la arki karaa in dahaarka FBE ee budada ah ee aan ka buuxin CTBN-EP prepolymers ay leeyihiin dildilaacyo yaryar oo muuqda (Jaantus 8 (1)), halka lakabyada ay ka buuxaan CTBN-EP prepolymers (Jaantus 8 (2-3)) ma laha dildilaacyo muuqda, oo tilmaamaya ku dheggan iyo adkaanta wanaagsan.

U adkaysta imtixaannada foorarsiga ee daaha budada FBE

Sawirka 9 wuxuu muujinayaa iska caabbinta foorarsiga natiijooyinka tijaabada ee saddexda nooc ee daaha budada FBE. Iska caabbinta foorarsiga budada FBE iyada oo aan la buuxin CTBN-EP prepolymers waa mid liidata (Sawir 9 (1)), iyo ifafaale guul darro ah oo wadajir ah ayaa la helay. Marka CTBN-EP prepolymers lagu daro daahan budada ah, caabbinta foorarsiga ee daaha budada FBE ayaa si aad ah loo wanaajiyay iyada oo la kordhinayo maadada CTBN-EP prepolymers (Fig.9 (2-3)), mana jirto dhacdo guuldarro isku xidhan oo la helay , taasoo muujinaysa caabbinta sare ee foorarsiga.

Tijaabada buufinta milixda ee dahaarka

Iska caabbinta dahaarka ee dahaarka waxaa lagu qiimeeyaa iyadoo loo soo bandhigayo dahaarka jawi ceeryaamo milix ah oo ay dhaliso 5wt% aqueous NaCl xal 35 ± 2 °C 3000 h sida waafaqsan ISO 14655: 1999 qeexitaanka. Ka dib marka laga saaro qolka ceeryaamo milix ah, dhammaan shaybaarada waxaa lagu dhaqaa biyo nadiif ah si looga saaro wixii hadhaaga ah, daxalka daaha ayaa la arkay. Waxaa laga arki karaa Fig.10, ka dib markii dahaarka waxaa ka buuxsamay CTBNEP prepolymers (Fig.10b), ma jiraan wax caddayn ah miridhku, iyo shaybaarada waa fasax-free, taasoo muujinaysa iska caabin ah daxalka ee daahan filled prepolymers CTBN EP. buuxin kara shuruudaha heerka.

Iska caabbinta daxalka ee daahan organic oo aan cillado ku xiran tahay inta badan sifooyinka ay caqabad, ie, sida ay u yaraynaysaa faafin ee qoyaanka iyo daxalka ions iyada oo loo marayo filimka. Waxa ka mid ah halbeegyada gacan ka geysta guryaha xannibaadda waa weerarka substrate-ka birta ah ee hoose. Dahaarka u dhow aagga qaawan ayaa ku abuura lakab maran substrate kaas oo ka hortagaya daxal kale. Sidaa darteed, waxay si fudud u qabsan kartaa ion-yada (malaha Cl-) si ay u samaysato polymer-ka doped-ka ah.
