2. Riƙewar ruwa
Riƙewar ruwa yana ɗaya daga cikin mahimman ayyukan ethers cellulose. Zai iya ɗaukar ruwa mai yawa a cikin mannen tayal, yana ba da damar sakin ruwa a hankali. Wannan aikin yana da mahimmanci ga amsawar hydration na kayan tushen siminti kuma kai tsaye yana shafar tsarin warkewa da abubuwan haɗin haɗin gwal ɗin tayal.
Taimakon amsawar hydration: Riƙewar ruwa na ethers cellulose yana tabbatar da cewa siminti yana da isasshen ruwa don hydration yayin aiwatar da ƙarfi, wanda ke da mahimmanci don haɓaka ƙarfi da haɗin kai na adhesives.
Tsawaita lokacin buɗewa: Saboda riƙewar ruwa yana ƙara yawan lokacin danshi a saman manne, ma'aikatan gine-gine suna da ƙarin lokaci don daidaitawa da matsayi, don haka inganta ingantaccen gini.
3. Ingantattun kaddarorin rheological
Cellulose ethers suna da tasiri mai mahimmanci akan rheological Properties na tayal adhesives. Rheology yana nufin kwarara da halayen lalacewa na wani abu a ƙarƙashin damuwa. Cellulose ethers iya daidaita yawan amfanin ƙasa danniya da thixotropy na m, game da shi inganta ta workability.
Samar da danniya iko: Cellulose ethers na iya samar da wani ƙarfin tsari a cikin manne, don haka ana buƙatar wani ƙarfin waje don fara colloid don gudana. Wannan yana taimakawa hana abin da ake amfani da shi daga sawa ko zamewa yayin gini.
Ingantaccen Thixotropy: Cellulose ethers yana sanya mannen tayal yana nuna babban danko lokacin da yake tsaye, amma danko yana raguwa da sauri a ƙarƙashin aikin ƙarfin ƙarfi, yana sauƙaƙa yadawa da yadawa yayin gini. Bayan an kammala ginin, an sake dawo da danko, wanda ke taimakawa wajen kiyaye tayal.
4. Inganta aikin anti-sag
Lokacin shigar da fale-falen fale-falen fale-falen buraka a tsaye ko karkatacce, hana manne daga zamewa lamari ne mai mahimmanci. Cellulose ethers da kyau inganta anti-sag yi na adhesives ta hanyar thickening da rheology daidaita ayyukan, kyale colloid da tabbaci gyara fale-falen buraka a tsaye yi.
Sarrafa Sag: Cellulose ethers na iya samar da tsarin gel tare da haɗin kai mai girma, wanda ke sa manne yana da damuwa mai girma a kan saman tsaye, don haka ya hana fale-falen daga zamewa.
5. Ingantattun ƙarfin haɗin gwiwa
Cellulose ethers suna taka muhimmiyar rawa wajen haɓaka ƙarfin haɗin gwiwa na adhesives. Riƙewar ruwa da kaddarorin rheological yana ba da damar mannen tayal don mafi kyawun kutsawa saman fale-falen fale-falen fale-falen fale-falen fale-falen buraka da abubuwan da ake amfani da su, don haka inganta adhesion.
Yin aikin jika: Cellulose ethers suna daidaita ruwa na adhesives don ba su damar kutsawa da kyau da mannewa saman fale-falen fale-falen fale-falen fale-falen fale-falen buraka, haɓaka yankin haɗin gwiwa, da haɓaka ƙarfin haɗin gwiwa.
Ingantacciyar daidaituwa: Saboda tasirin kauri na ethers cellulose, ana rarraba abubuwan haɗin gwiwa daidai gwargwado, rage matsalar ƙarancin haɗin kai wanda ke haifar da lalata kayan gida.
6. Hana fashewa
Tile adhesives suna da wuya ga raguwa da raguwa saboda asarar ruwa a lokacin bushewa da taurin aiki. Abubuwan da ke riƙe da ruwa na ethers cellulose na iya rage raguwar asarar ruwa yadda ya kamata, rage bushewar bushewa, da hana samuwar fashewa.
Gudanar da bushewar bushewa: Ta hanyar sarrafa adadin sakin ruwa, ethers cellulose na iya rage raguwar adhesives yayin aikin bushewa, ta haka rage haɗarin fashewa.
7. Inganta yanayin juriya da karko
Hakanan ethers na cellulose na iya inganta juriya na yanayi da dorewar mannen tayal. Babban kwanciyar hankali a cikin yanayin jika na iya haɓaka aikin mannewa a cikin mahalli mai ɗanɗano da haɓaka ƙarfin tsufa.
Juriya na danshi: Cellulose ethers na iya ci gaba da kula da ayyukansu a cikin yanayi mai laushi, wanda ke taimakawa adhesives na tayal don kula da mannewa na dogon lokaci a ƙarƙashin yanayin danshi.
Anti-tsufa: Cellulose ethers suna haɓaka ɗorewa na dogon lokaci na mannewa ta hanyar kare simintin siminti daga asarar danshi mai sauri da zaizayar muhalli.
8. Amintaccen muhalli
Ana samun ethers na cellulose daga cellulose na halitta kuma ana yin su ta hanyar gyaran sinadaran. Suna da kyakkyawan yanayin halitta da kuma abokantaka na muhalli. A cikin mahallin kayan gini na yau waɗanda ke ƙara mai da hankali kan kariyar muhalli da ci gaba mai dorewa, ethers cellulose suna da fa'idodi masu mahimmanci azaman ƙari mai aminci da inganci.
Aikace-aikacen ethers cellulose a cikin tile adhesives shine mabuɗin don inganta aikin su. Its thickening, ruwa riƙewa, rheology gyara, anti-sagging, ingantattun bonding, da fasa rigakafin kaddarorin muhimmanci inganta yi yi da kuma karshe sakamako na tayal adhesives. A lokaci guda, lafiyar muhalli na cellulose ethers kuma ya cika ka'idodin kare muhalli na kayan gini na zamani. A matsayin wani abu mai mahimmanci na kayan aiki, ethers cellulose za su ci gaba da taka muhimmiyar rawa a fagen gina adhesives, taimakawa ci gaba da ingantaccen tsarin shimfidar tayal mai dorewa.
