Tasirin Methyl Hydroxyethyl Cellulose akan Matrix Epoxy Resin Matrix

Methyl Hydroxyethyl Cellulose (MHEC) shine ether cellulose mai narkewa da ruwa wanda ake amfani dashi sosai a cikin masana'antar gini azaman thickener da rheology modifier a cikin tsarin siminti.An san shi don haɓaka kaddarorin kwarara, iya aiki, da manne da kayan siminti, yana mai da shi ingantaccen ƙari don siminti, turmi, da grout formulations.Koyaya, tasirin MHEC akan kaddarorin matrices resin epoxy ya sami ƙarancin kulawa.

Epoxy resins wani nau'in nau'in polymers ne na thermosetting waɗanda ake amfani da su sosai a cikin sararin samaniya, kera motoci, da masana'antar gini saboda kyawawan kaddarorin injin su, juriyar sinadarai, da mannewa ga sassa daban-daban.Duk da haka, suna iya zama mai karye kuma suna nuna ƙarancin tasiri, wanda ke iyakance amfani da su a wasu aikace-aikace.Don magance wannan batu, masu bincike sun binciki amfani da nau'o'in addittu daban-daban, ciki har da ethers cellulose, don inganta tauri da tasiri na resin epoxy.

Yawancin karatu sun ba da rahoton amfani da MHEC azaman ƙari a cikin matrices resin epoxy.Misali, binciken Kim et al.(2019) yayi bincike akan tasirin MHEC akan kayan aikin injina na tushen abubuwan haɗin gwiwa.Masu binciken sun gano cewa ƙari na MHEC ya inganta ƙarfin karaya da ƙarfin tasiri na abubuwan da aka haɗa, da kuma kwanciyar hankali na thermal da juriya na ruwa.Marubutan sun danganta waɗannan haɓakawa ga iyawar MHEC don samar da haɗin gwiwar hydrogen tare da matrix resin matrix na epoxy, wanda ya ƙara mannewar fuska kuma ya hana yaduwa.

Wani binciken da Pan et al.(2017) ya bincika tasirin MHEC akan halayen warkarwa da kaddarorin injiniya na tsarin resin epoxy.Masu binciken sun gano cewa ƙari na MHEC yana jinkirta lokacin warkewa kuma ya rage matsakaicin zafin jiki na resin epoxy, wanda aka danganta da yanayin hydrophilic na MHEC.Duk da haka, ƙari na MHEC kuma ya inganta ƙarfin ƙarfi da haɓakawa a lokacin hutu na resin epoxy da aka warke, yana nuna cewa MHEC na iya inganta sassauci da taurin matrix epoxy resin matrix.

Baya ga inganta kayan aikin injiniya na epoxy resin matrices, MHEC kuma an ba da rahoton cewa yana da tasiri mai kyau akan kaddarorin rheological na tsarin tushen epoxy.Misali, binciken Li et al.(2019) ya bincika tasirin MHEC akan rheology da kaddarorin injiniyoyi na mannen tushen epoxy.Masu binciken sun gano cewa ƙari na MHEC ya inganta halayen thixotropic na manne kuma ya rage daidaitawar filaye.Bugu da ƙari na MHEC kuma ya inganta ƙarfin mannewa da tasiri mai tasiri na m.

Gabaɗaya, amfani da MHEC azaman ƙari a cikin matrix resin epoxy ya nuna sakamako masu ban sha'awa a cikin haɓaka kayan aikin injiniya, tauri, da halayen rheological na tsarin.Ƙarfin MHEC don samar da haɗin gwiwar hydrogen tare da matrix resin resin matrix an yi imanin shine maɓalli mai mahimmanci a bayan waɗannan ingantawa, wanda zai iya haifar da ƙarar mannewar fuska da kuma rage yaduwa.Duk da haka, ana buƙatar ƙarin bincike don cikakken fahimtar tasirin MHEC akan kaddarorin matrices resin epoxy da inganta amfani da wannan ether na cellulose a cikin tsarin tushen epoxy.
