A cikin kayan ado na gine-gine, putty shine kayan mahimmanci don daidaita bango da kuma firamare, wanda ke da alaƙa kai tsaye da ingancin gini da tasirin kayan ado na kayan shafa na gaba, bangon bangon bango da sauran ƙarewa. Domin inganta yi yi da kuma amfani da yi na putty, wani rabo dagacellulose etherAna ƙara ƙarawa a cikin tsarin sa. A cikin 'yan shekarun nan, ether cellulose da aka gyara ya zama a hankali a hankali a cikin samar da putty saboda kyakkyawan aikinsa.
1. Bayanin ethers cellulose da aka gyara
Cellulose ether wani nau'i ne na mahaɗan polymer mai narkewa ko tarwatsawa wanda aka yi ta hanyar etherifying da gyaggyarawa wani ɓangare na ƙungiyoyin hydroxyl na cellulose na halitta ta hanyoyin sinadarai. Common cellulose ethers sun hada da hydroxypropyl methylcellulose (HPMC), methyl cellulose (MC), sodium carboxymethyl cellulose (CMC-Na), da dai sauransu The abin da ake kira "gyara" cellulose ether yana nufin gabatar da aiki substituents ko tsari na tsarin a kan tushen na asali cellulose ether don inganta ruwa juriya, solubility da dai sauransu. don mafi kyawun biyan buƙatun don aikin kayan aiki a aikace-aikacen gini.
2. Tsarin aikin aikin ether cellulose da aka gyara a cikin putty
Wall putty sau da yawa hada da inorganic kayan kamar lemun tsami foda, siminti, talcum foda, da dai sauransu Wadannan kayan ne mai sauki hazo, delaminate, crack ko da rashin aikin yi na gini bayan ƙara ruwa da motsawa. Bayan ƙara haɓakar ether cellulose, galibi yana taka rawa a cikin putty:
Ingantaccen riƙewar ruwa: Modified cellulose ether yana da matuƙar ƙarfi sha ruwa da kuma riƙe ruwa, wanda zai iya kulle ruwa da ƙarfi, hana ruwa daga evaporating da sauri ko a sha da tushe Layer a lokacin gina, don haka tabbatar da cewa putty yana da isasshen hydration dauki lokaci, inganta bonding ƙarfi da kuma rage hadarin fatattaka.
Inganta aikin ginin: Cellulose ether na iya ba da kyakkyawan zamewa da kaddarorin gogewa, rage juriya yayin gini, kuma ya sa ginin ya fi sauƙi da sauƙi. A lokaci guda kuma, tasirinsa mai kauri zai iya inganta haɓakar ruwa da dakatarwar putty, da kuma hana abu daga nutsewa da delamination.
Ingantacciyar ƙarfin haɗin gwiwa: An kafa tsarin cibiyar sadarwa mai kyau tsakanin ether cellulose da aka gyara da samfurin hydration na siminti, wanda ke taimakawa haɓaka haɗin kai tsakanin putty da tushe mai tushe da haɓaka gabaɗayan mannewa.
Excellent anti-sagging dukiya: Good thixotropic Properties sa putty kasa iya sag a lokacin facade yi, kuma zai iya samar da wani lebur, uniform lokacin farin ciki shafi, inganta yi yadda ya dace da kuma gama samfurin effects.
Ingantattun kwanciyar hankali da ajiya: Gyaran ether cellulose na iya hana rarrabuwa, hazo, da haɓakar putty yayin sufuri da ajiya, da haɓaka kwanciyar hankali na samfurin.
3. Hanyoyin gyare-gyare da haɓaka aiki
Hanyoyin gyare-gyare na gama gari sun haɗa da gabatar da ƙungiyoyin hydrophobic, canza matakin maye gurbin, da daidaita rarraba nauyin kwayoyin halitta. Alal misali, HPMC hydrophobically modified (kamar HPMC-M) iya kara inganta ruwa juriya da kuma lokacin farin ciki shafi na putty, da kuma sarrafa etherification dauki yanayi, kayayyakin da takamaiman gel zafin jiki da rheological hali za a iya samu don saduwa da gina bukatun daban-daban sauyin yanayi da tushe yanayi.
Hakanan akwai samfuran ether na cellulose na musamman waɗanda aka haɓaka don aikace-aikacen daban-daban, irin su babban zazzabi na gel HPMC wanda ya dace da ginin zafin jiki mai ƙarfi, ƙarancin danko da babban riƙewar ruwa HPMC, da dai sauransu, don saduwa da kasuwa daban-daban da buƙatun tsari.
4. Kariya don amfani
A cikin aiwatar da ƙirar ƙirar putty da samarwa, yakamata a lura da waɗannan abubuwan yayin amfani da ether cellulose da aka gyara:
Sarrafa adadin ƙari, gabaɗaya 0.2% zuwa 0.5% na nauyin busassun busassun foda; da yawa na iya rinjayar lokacin bushewa da aikin shafi na gaba.
Kafin busasshen hadawa yakamata ya zama iri ɗaya sannan a zuga shi da ruwa don tabbatar da cewa ether ɗin cellulose ya tarwatse sosai kuma ba tare da kullu ba.
Zaɓi nau'in ether cellulose mai dacewa bisa ga yanayin ginin (kamar zazzabi, zafi) da nau'in putty (bangon ciki, bangon waje, nau'in ruwa, da dai sauransu).
A matsayin ƙari na aiki tare da kyakkyawan aiki,cellulose ether canzayana taka muhimmiyar rawa da ba za a iya maye gurbinsa ba a cikin samarwa da aikace-aikacen putty. Ba wai kawai yana inganta ingantaccen ginin gini da kaddarorin jiki na putty ba, amma kuma yana ba da ƙarin abin dogaro da ingantaccen bayani don maganin tushe na bango. Tare da ci gaba da haɓakar gine-ginen kore da kyawawan ra'ayoyin gine-gine, buƙatun kayan aiki mai girma yana haɓaka, kuma buƙatun aikace-aikacen ether na ether da aka gyara a fagen kayan gini zai fi girma.
