Mu matope owuma, cellulose ether ndi chowonjezera chachikulu chomwe chimatha kusintha matope onyowa ndikukhudza matope omanga matope. Methyl cellulose ether imagwiritsa ntchito gawo la kusungidwa kwamadzi, kukulitsa, komanso kusintha magwiridwe antchito. Zochita zabwino zamadzi zimatsimikizira kuti matope sadzayambitsa misampha, utsi ndi kuchepetsa mphamvu chifukwa cha kuchepa kwa madzi komanso simenti yokwanira ya simenti; Kukula kwamphamvu kwa matope onyowa kumachulukitsidwa kwambiri, ndipo kuwonjezera kwa methyl cellulose ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ndi kuwononga zinyalala; Kuphatikiza apo, osiyanasiyana gawo la cellulose ndi losiyananso, mwachitsanzo: cellulose mu ma pile m'matumbo amatha kuwonjezera nthawi yotseguka ndikusintha nthawi; cellulose mu matope opanga matope amatha kusintha kulimba kwa matontho; Podzilimbitsa, cellulose imatenga gawo popewa kukhazikitsa, kusankhana ndi stratization.
Kupanga kwa cellulose ether kumapangidwa makamaka ndi ulusi wachilengedwe kudzera m'mabwinja a alkalini, kugwirira ntchito (kutsuka), kuchapa, kuwuma, kupera ndi kupera ndi njira zina. Zida zopangira zitsulo zopangira zachilengedwe zitha kugawidwa: fiberni fiber, geber fiber, etc. Mulingo wa ma polymerization omwe amawoneka. Pakadali pano, opanga ma cellulose amagwiritsa ntchito fiber thonje (mwa-corticlellulose) ngati zinthu zazikuluzikulu. Cellulose eder amatha kugawidwa mu Ionic komanso osakhala ionic. Mtundu wa Ionic makamaka umaphatikizapo carboxymethyl cellulose mchere, ndipo mtundu womwe sunakhale inic makamaka cellose, methyl hydroumeyl (proyyl hydroxethyl, ndi hydroxyethyl cellulose. Su ndi zotero. Mu matope a ufa wa ufa, chifukwa Ionic cellulose (carboxymethyl cellulose mchere) siyikugwiritsidwa ntchito popanga ma calcium ions monga simenti youma ngati zinthu zina.
Kusungidwa kwamadzi kwa cellulose kumakhudzananso ndi kutentha komwe kumagwiritsidwa ntchito. Kusunga kwamadzi kwa methyl cellulose ether kumachepetsa ndi kuchuluka kwa kutentha. Mwachitsanzo, nthawi yachilimwe, ikamawala, khoma lakunja limakhala lopakidwa, lomwe nthawi zambiri limathandizira kuchiritsa simenti ndi matope. Kulimbana ndi kuchepa kwa kuchuluka kwa madzi osunga madzi kumabweretsa malingaliro omwe onse omanga ndi magwiridwe antchito otsutsa amakhudzidwa. Pankhaniyi, ndizowopsa kuti muchepetse mphamvu ya kutentha. Nthawi zina sizingakwaniritse zosowa zogwiritsira ntchito. Mankhwala ena amachitika pa cellulose, monga kuwonjezera kuchuluka kwa chikondwerero, etc., kotero kuti madzi osasunga akhoza kupitirizanso kutentha kwabwino kwambiri.
Water retention of cellulose: The main factors affecting the water retention of mortar include the amount of cellulose added, the viscosity of cellulose, the fineness of cellulose, and the temperature of the operating environment.
Makulidwe a cellulose: Kulankhula kwa mafalowa, koma ma virus apamwamba, okwera kwambiri olemera kwambiri cellulose, ndipo amachepetsa ofanana mu kusungunuka, zomwe zimasokoneza ntchito yake yomanga ndi mphamvu yamatope. Maonekedwe ake, zoonekeratu kuti zimakula kwambiri patavala matope, koma siyofanana mwachindunji. Matope apamwamba, matope owoneka bwino adzakhala. Pakumanga, idzamatira khwiye ndikutsatira kwambiri, koma sizithandiza kwambiri kuwonjezera mphamvu ya matope onyowa, ndipo magwiridwe antchito a Anti-A Anti-Anti-Anti sawonekera pakumanga.
Chisangalalo cha cellulose: Ubwino umakhudza kusungunuka kwa cellulose ether. Ma celluuse nthawi zambiri amakhala granur ndipo amabalalika mosavuta m'madzi popanda kuphatikizika, koma kuchuluka kwa chilengedwe kumachedwa kwambiri. Sioyenera kugwiritsa ntchito matope a ufa. Moto wa Cellulose ndiyabwino kwambiri. Ufa wokhawo wokwanira umatha kupewa methl cellulose ether sgglomet powonjezera madzi ndi kusuntha. Koma etherker cellulose ether sizingowononga komanso zimachepetsa mphamvu zakomweko kwa matope. Pamene matope owuma ufa atamangidwa m'dera lalikulu, liwiro la matope akomweko mwachionekere limachepetsedwa, ndipo ming'alu chifukwa cha nthawi youritsa imawoneka. Chifukwa cha nthawi yayifupi, matope okhala ndi zomangamanga amafunikira zabwino zambiri.
