Putty foda abu ne na ginin da aka saba amfani dashi, galibi ana amfani dashi don daidaita bango, cika fasa da samar da fili mai santsi don zane da ado na gaba. Cellulose ether yana daya daga cikin mahimman abubuwan da ake amfani da su a cikin sa foda, wanda zai iya inganta aikin gine-gine da ingancin foda. Wannan labarin zai gabatar da cikakken bayani game da takamaiman aikace-aikacen ethers cellulose a cikin putty foda da mahimmancinsa ga masana'antar gine-gine.
1. Abubuwan asali da ayyuka na ethers cellulose
Cellulose ether wani nau'in fili ne na polymer mai narkewa da ruwa wanda aka samu ta hanyar gyare-gyaren sinadarai ta amfani da cellulose na halitta azaman albarkatun ƙasa. Tsarinsa na kwayoyin halitta ya ƙunshi babban adadin ƙungiyoyin hydrophilic (kamar hydroxyl, methoxy, da dai sauransu), wanda ke ba da ether cellulose mai kyau ruwa mai narkewa da kuma ƙarfin girma. A cikin aikace-aikace na putty foda, muhimmiyar rawa na ether cellulose yana nunawa a cikin wadannan bangarori:
Tasiri mai kauri
Cellulose ether iya muhimmanci ƙara danko na putty foda slurry, sa shi da kyau thixotropy da kwanciyar hankali, don haka sauƙaƙe yi. Bugu da ƙari, yana iya daidaita halayen rheological na slurry don hana ƙwayar putty daga gudana ko zamewa daga bango, tabbatar da ci gaba mai kyau na ginin.
Riƙewar ruwa
Babban riƙewar ruwa na ether cellulose yana ɗaya daga cikin mahimman halayensa lokacin amfani da foda. A lokacin aikin ginin, bayan an yi amfani da foda a bango, zubar da ruwa zai iya sa foda ya bushe ya bushe. Cellulose ether na iya jinkirta asarar ruwa yadda ya kamata, yana haifar da slurry don saki ruwa a hankali yayin aikin bushewa, don haka inganta mannewa na putty, guje wa bushewa da fashewa, da tabbatar da santsi na bangon bango.
Inganta iya aiki
Kasancewar ether cellulose yana inganta aikin ginawa na putty foda. Alal misali, yana iya inganta sassauci na putty, yana sauƙaƙa wa ma'aikatan gine-gine don goge abin da aka sanya a ko'ina. Bugu da ƙari, ether cellulose kuma zai iya rage samar da kumfa a kan putty surface da kuma inganta santsi, don haka inganta kayan ado sakamako.
Ƙara sa'o'in buɗewa
A cikin ginin, lokacin buɗewa na putty foda, wato, lokacin daga aikace-aikacen zuwa bushewa da ƙarfafa kayan aiki, muhimmin ma'auni ne wanda ma'aikatan ginin ke kula da su. Cellulose ether na iya tsawaita lokacin buɗewa na putty, rage haɗin gwiwa da rashin daidaituwa yayin gini, don haka inganta haɓakar bangon gabaɗaya.
2. Aikace-aikacen ether cellulose a cikin yanayi daban-daban na putty foda
Ciki bango putty
A cikin aikace-aikacen bangon bangon ciki, ether cellulose ba kawai inganta aikin aiki ba, amma kuma yana iya daidaita ruwa da mannewa na putty don tabbatar da santsi da adhesion na bangon bango. Bugu da ƙari, babban aikin riƙewar ruwa na ether cellulose zai iya hana putty daga fashewa saboda saurin zubar da ruwa a lokacin aiwatar da aikace-aikacen, kuma ya dace da bukatun kwanciyar hankali na dogon lokaci a cikin yanayin bushewa na cikin gida.
Fuskar bangon waje
Fuskar bangon waje yana buƙatar samun ƙarfin juriya na yanayi da juriya, saboda yanayin bangon bangon na waje zai shafi yanayin yanayi, bambance-bambancen yanayin zafi da sauran dalilai. Aikace-aikacen ether cellulose a cikin bangon bango na waje na iya inganta haɓakar ruwa, juriya da mannewa, yana ba shi damar daidaitawa ga canje-canje a cikin yanayin waje kuma ya tsawaita rayuwar sabis. Bugu da kari, ether cellulose kuma na iya taimakawa putty inganta juriya ta UV, juriya-narke da sauran kaddarorin, ta yadda bangon bangon waje har yanzu zai iya kula da kaddarorin jiki a karkashin yanayi na waje.
mai hana ruwa
Putty mai hana ruwa ya dace da yanayin zafi mai zafi kamar dakunan wanka da dafa abinci, kuma yana buƙatar babban hana ruwa da juriya na ruwa na putty. Cellulose ether na iya haɓaka aikin hana ruwa na putty bisa ga tabbatar da kyakkyawan mannewa da aiki. Bugu da kari, da thickening da ruwa-retaining effects na cellulose ether damar waterproofing putty don kula da kyau kwanciyar hankali a cikin yanayi tare da high zafi da kuma kauce wa mildew matsaloli a kan bango.
Babban kayan ado na kayan ado
Babban kayan ado na kayan ado yana da babban buƙatu don kwanciyar hankali da kyau, kuma galibi ana amfani dashi a manyan wuraren zama, otal-otal da sauran wurare. Cellulose ether na iya taimakawa wajen daidaita abubuwan da ake amfani da su na putty, inganta sassaucin yanayi, inganta sassauci da kuma aiki na putty, rage kumfa da sutura, yin tasirin kayan ado mafi kyau, da saduwa da bukatun kayan ado na wurare masu tsayi.
3. Zaɓin fasaha na ether cellulose a cikin sa foda
Dangane da buƙatun aikace-aikacen da buƙatun aikin daban-daban na putty foda, ana amfani da ethers na cellulose masu zuwa a cikin masana'antar gini:
Hydroxypropyl methylcellulose (HPMC)
HPMC ƙari ne na gini da aka saba amfani da shi tare da kyakkyawan riƙewar ruwa da tasirin kauri. Ana amfani da shi sosai wajen kayan gini kamar na ciki da na waje da bangon bango, adhesives na tayal, da kuma plastering turmi. Zai iya inganta juriya na sag da aikin aiki na putty foda, kuma ya dace musamman ga buƙatun kayan daɗaɗɗen danko.
Hydroxyethylmethylcellulose (HEMC)
HEMC yana da kyakkyawan aikin riƙe ruwa da kwanciyar hankali, musamman a cikin ƙananan yanayin zafi, kuma har yanzu yana iya kula da solubility mai kyau, don haka ya dace don amfani da bangon bango na waje. Bugu da ƙari, HEMC yana da tasiri mai kyau a kan inganta tarwatsawa da daidaituwar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar ƙwayar cuta.
Carboxymethyl cellulose (CMC)
CMC shine kauri mai narkewa da ruwa. Ko da yake yana da ƙarancin riƙewar ruwa da abubuwan hana sag, farashin sa yana da ƙasa. Ana amfani dashi sau da yawa a cikin foda wanda baya buƙatar ɗaukar ruwa mai yawa kuma ya dace da aikace-aikacen putty na bango na gaba ɗaya.
4. Abubuwan da ake bukata da kuma abubuwan da ke faruwa na ethers cellulose a cikin masana'antun foda na putty
Tare da ci gaba da ci gaban masana'antar gine-gine, bukatun mutane don inganci, kariyar muhalli da kayan ado na kayan ado sun karu a hankali, kuma aikace-aikacen ethers na cellulose ya zama mai girma. A cikin ci gaba na ci gaba na ci gaba na masana'antun foda na putty, aikace-aikacen ether cellulose zai mayar da hankali kan abubuwa masu zuwa:
Kore da kuma kare muhalli
A halin yanzu, kayan gine-gine masu dacewa da muhalli suna da zafi a cikin masana'antar gine-gine. A matsayin abu na polymer wanda aka samo daga cellulose na halitta, cellulose ether ya dace da manufar kare muhalli na kore kuma yana iya rage ƙazantaccen kayan ado. A nan gaba, za a haɓaka da amfani da ƙananan ƙananan VOC (magungunan kwayoyin halitta masu banƙyama) da samfurori na cellulose ether masu girma.
Nagartaccen kuma mai hankali
Ci gaba da haɓaka ether cellulose yana ba da damar putty foda don kula da kwanciyar hankali a cikin mahalli masu rikitarwa. Misali, ta hanyar inganta tsarin kwayoyin halitta da ƙari na additives, putty foda yana da ƙarfin daidaitawa da kayan warkarwa da kai, yana sa kayan gini su zama masu hankali da inganci.
Yawanci
Duk da yake inganta ainihin kaddarorin putty foda, cellulose ethers kuma na iya sa putty foda suna da ƙarin ayyuka kamar su antibacterial, anti-mildew, da anti-UV don saduwa da bukatun ƙarin yanayin aikace-aikace na musamman.
Aikace-aikacen ether cellulose a cikin foda ba wai kawai inganta aikin gine-gine da kuma dorewa na putty foda ba, amma kuma yana inganta tasirin kayan ado na bango, yana biyan bukatun gine-gine na zamani don bangon bango, santsi da karko. . Tare da ci gaba da ci gaban masana'antar gine-gine, aikace-aikacen ethers na cellulose a cikin foda na putty zai zama da yawa, yana tura kayan ado na gine-gine zuwa babban aiki da kare muhalli.
