Aikin cellulose ether a cikin turmi

Cellulose etherriƙe ruwa

Rike ruwa na turmi yana nufin ikon turmi don riƙewa da kulle ruwa. Mafi girman danko na cellulose ether, haka nan riƙon ruwa zai fi kyau. Saboda tsarin cellulose ya ƙunshi haɗin hydroxyl da ether, ƙungiyar haɗin hydroxyl da ether na atoms na oxygen da ƙwayoyin ruwa don haɗa haɗin hydrogen, don haka ruwa ya yantar da shi zuwa ruwa mai ɗaurewa, ruwa mai lanƙwasa, don taka rawar riƙe ruwa.

Narkewar cellulose ether

1. Ana iya watsa sinadarin cellulose ether mai kauri a cikin ruwa ba tare da ya taru ba, amma saurin narkewar sa yana da jinkiri sosai. Cellulose ether da ke ƙasa da raga 60 yana narkewa a cikin ruwa na tsawon mintuna 60.

2. Ƙananan ƙwayoyin cellulose ether a cikin ruwa suna da sauƙin warwatsewa kuma ba sa taruwa, kuma saurin narkewar yana da matsakaici. Cellulose ether sama da raga 80 yana narkewa a cikin ruwa na kimanin mintuna 3.

3. Ultrafine cellulose ether yana warwatse cikin sauri a cikin ruwa, yana narkewa da sauri kuma yana samar da ɗanko mai sauri. Cellulose ether da ke sama da raga 120 yana narkewa a cikin ruwa na tsawon daƙiƙa 10-30.

Mafi kyawun ƙwayoyin cellulose ether, mafi kyawun riƙe ruwa, ƙwayoyin cellulose ether masu kauri da saman hulɗar ruwa suna narkewa nan take kuma suna samar da wani abu na gel. Manne yana naɗe kayan don hana ƙwayoyin ruwa ci gaba da shiga. Wani lokaci, ko da an daɗe ana juyawa, maganin ba zai iya wargajewa ko narkewa daidai gwargwado ba, yana samar da maganin flocculent ko agglomerate mai laka. Ƙananan ƙwayoyin suna wargajewa kuma suna narkewa nan da nan bayan sun taɓa ruwa don samar da kamanni iri ɗaya.

Darajar PH na cellulose ether (jinkirin coagulation ko ƙarfin farko)

Ana sarrafa ƙimar PH na masana'antun cellulose ether a gida da ƙasashen waje a kusan 7, wanda yake da acidic. Saboda har yanzu akwai tsarin zoben glucose da yawa da ya bushe a cikin tsarin kwayoyin halitta na cellulose ether, zoben glucose da ya bushe shine babban rukuni wanda ke haifar da jinkirin siminti. Zoben glucose da ya bushe zai iya yin ions na calcium a cikin maganin hydration na siminti don samar da mahaɗan ƙwayoyin calcium na sukari, rage yawan calcium ion a lokacin shigar da siminti, hana samuwar da hazo na calcium hydroxide da calcium salt lu'ulu'u, don haka yana jinkirta tsarin hydration na siminti. Idan ƙimar PH ta zama yanayin alkaline, turmi zai bayyana yanayin ƙarfi da wuri. Yanzu yawancin masana'antu don daidaita ƙimar PH ta amfani da sodium carbonate, sodium carbonate wani nau'in wakili ne mai hanzarta haɓakawa, sodium carbonate na iya inganta aikin saman barbashi na siminti, yana haifar da haɗuwa tsakanin barbashi yana ƙaruwa, yana ƙara inganta danko na slurry, turmi da sodium carbonate da sinadarin calcium ion cikin sauri, yana haifar da samuwar ettringite, daskararren siminti da sauri. Saboda haka, ya kamata a daidaita ƙimar PH bisa ga abokan ciniki daban-daban a cikin ainihin tsarin samarwa.

Shigar da iskar gas ta cellulose ether

Shigar da iskar cellulose ether galibi saboda cellulose ether shima wani abu ne mai surfactant, aikin haɗin cellulose ether galibi yana faruwa ne a cikin haɗin gas-liquid-solid, na farko shine gabatar da kumfa, sannan sai ya watse da jika. Cellulose ether ya ƙunshi ƙungiyar alkyl, yana rage tashin hankali a saman ruwa da kuzarin fuska, ruwan da ke cikin ruwa yana da sauƙin samar da ƙananan kumfa da yawa a rufe.

Haɗa cellulose ether

Cellulose ether yana narkewa a cikin turmi saboda sarkar kwayoyin halitta ta methoxy da hydroxypropyl group a cikin slurry tare da calcium ions da aluminum ions a cikin samuwar viscous gel kuma an cika shi da gibin turmi na siminti, yana inganta yawan turmi, yana taka rawar cikawa mai sassauƙa da ƙarfafawa. Duk da haka, lokacin da aka matse matrix ɗin haɗin gwiwa, polymer ba zai iya taka rawa mai ƙarfi ba, don haka ƙarfin da matsi na turmi yana raguwa.

Samar da fim nacellulose ether

Ana samar da wani siririn fim na latex tsakanin ƙwayoyin cellulose ether da siminti bayan an yi ruwa. Fim ɗin yana da tasirin rufewa kuma yana inganta busar da turmi a saman turmi. Saboda cellulose ether yana da kyakkyawan riƙe ruwa, yana kula da isasshen ƙwayoyin ruwa a cikin turmi, don haka yana tabbatar da ƙarfin ruwan siminti da taurarewa da kuma ci gaba gaba ɗaya, yana inganta ƙarfin haɗin turmi, a lokaci guda yana inganta mannewar turmi na siminti, turmi yana da kyakkyawan filastik da tauri, yana rage lalacewar turmi.
