Cellulose etherili ndi madzi abwino kwambiri, omwe amatha kuletsa chinyezi mu matope onyowa kuchokera mu utokha kapena kuwonekeranso ndi simenti ndi hydrate kwathunthu, zomwe ndizopindulitsa kwambiri -layer matope ndi zigawo zoyamwa madzi kapena matope opangidwa pansi pa kutentha ndi malo owuma. Madzi osunga ma cellulose ether amatha kusintha njira yomanga yachikhalidwe ndikuwongolera kupita patsogolo. Mwachitsanzo, kupatsa nyumba zomanga kumatha kuchitika m'madzi otsekemera madzi popanda kunyowa.
Maonekedwe, Mlingo, kutentha kwa ma cellulose ether kukhala ndi mphamvu kwambiri pamayendedwe ake osungira madzi. Pansi pazomwezo, mafashoni ambiri a ethel ether, kusungitsa kwamadzi kuli bwinobwino; Mlingo wapamwamba, kusungitsa kwamadzi. Nthawi zambiri, etherse yochepa kwambiri imatha kusintha madzi osungira matope. Mlingo ukafika pamlingo wina pomwe madzi osungidwa amadzi amawonjezeka, zomwe zimachitika kwa madzi osunga madzi amachepetsa; Pamene kutentha kwa kutentha kumakwera, kusungira kwamadzi kwa ethel nthawi zambiri kumachepetsa, koma cellusese yosinthika imakhalanso ndi madzi osungidwa bwino otentha; Mitundu yokhala ndi madigiri otsika a vegage ethen ether ali ndi magwiridwe antchito abwino.
Gulu la hydroxyl pa cellulose ethel Molekyu ndi Oxygen Colect Commet Commuenge Commet Comment Country Commet Conser the water molecule and the cellulose ether molecular chain Interdiffusion allows water molecules to enter the interior of the cellulose ether macromolecular chain and is subject to strong binding forces, thereby forming bound water and entangled water, which improves the water retention of cement slurry; cellulose ether imathandizira bwino simenti yatsopano. The rheological properties, porous network structure and osmotic pressure or the film-forming properties of cellulose ether hinder the diffusion of water.
Cellulose ether amataya matope onyowa ndi mawonekedwe abwino kwambiri, omwe amatha kuwonjezera luso pakati pa matope ndi malo osanjikiza a matope. Amagwiritsidwa ntchito kwambiri mu matope, njerwa zimagwirizanitsa matope ndi khoma lakunja khoma. Mphamvu ya etherse ether ether amathanso kuwononga mphamvu zotsutsa, kupewa kufooka kwakunja, tsankho komanso kutuluka konkriti.
Mphamvu ya kukula kwa cellulose pazinthu za simenti zimachokera ku mamasukidwe a eleeuse ether. M'mikhalidwe yomweyi, mafayilo apamwamba a ether ether, ma virus abwino kwambiri osinthika, koma ngati ma viruwo ndiwokwera kwambiri, koma ). Matope okhathamira komanso konkriti wodziletsa, zomwe zimafuna kuti madzi am'mwamba, amafunikira mafayilo otsika a cellulose. Kuphatikiza apo, kusintha kwa kukula kwa cellulose ether kumakulitsa kuchuluka kwa zinthu za simenti ndikuwonjezera zokolola za matope.
Makutu a eleuluse eleuluse amadalira zinthu zotsatirazi: Kulemera kwa kuchuluka kwa cellulose ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether ether, kupsinjika, kutentha, kutentha, mtengo wamaso ndi njira yoyesera. Pansi pa mikhalidwe yomweyo, molencular kulemera kwa cellulose ether, mafayilo apamwamba a yankho; Kukula kwakukulu, mafayilo apamwamba a yankho. Mukamagwiritsa ntchito, chisamaliro chikuyenera kumwedwa kuti chisapewe kuchuluka kwambiri ndikukhudza matope ndi matope; cellulose ether mawonekedwe a ether solution imachepera ndikuwonjezeka kwa kutentha, ndi kuchuluka kwa kuchuluka kwa kuchuluka kwa kutentha; cellulose ether nthawi zambiri nthawi zambiri imasungunuka kwamadzimadzi owonda, kutalika kwakukulu pakuyesedwa, kochepa kwambiri Kufuula kwa matope, kuti matope atha kukhala ogwira mtima komanso akomwe nthawi imodzi; Chifukwa yankho la cellulose sikuti ndi osadziwika kuti amadzimadzi, pamene njira zoyesera, zida ndi zida kapena zida zoyeserera zomwe zimagwiritsidwa ntchito pofuna kudziwa zomwezi ndi zomwezo zimasiyana kwambiri.
Cellulose ethel mamolekyulu amatha kukonza mamolekyulu amadzi atsopano kumapeto kwa ma moleculary unyolo, potero ukuwonjezera mafayilo. Ma unyolo a maselo a cellulose amagwirizana kuti apange mawonekedwe a mitundu itatu, yomwe imapangitsanso yankho lake la magazi kukhala mafayilo abwino.
Mawonekedwe apamwamba kwambiri cellulose a mu chixotropy ali ndi hixotropy, yomwe ilinso chinthu chachikulu cha cellulose ether ether. Mankhwala am'madzi amethyl celluloseNthawi zambiri zimakhala ndi madzi amtundu wa pseudopropric komanso osachimwa pansi pa kutentha kwake, koma onetsetsani katundu wa Newtonian ku mitengo yotsika. Pseudoplation imachulukana ndi kulemera kwa maselo kapena ndende ya ethel ether, mosasamala mtundu wa gawo la mpweya wolowa m'malo mwake. Chifukwa chake, cellulose edi ya kalasi ya ma visce yomwe ija, ziribe kanthu mc, hpmc, hemc, nthawi zonse imawonetsa zomwezo ngati kuchuluka kwa zomwe zimachitika nthawi zonse. Ma gels amapangidwa kuti kutentha kukuwukitsidwa, komanso kutulutsa kambiriko kwambiri. Kukhazikika kwambiri komanso kutsika kwa ma vinclose yotsika cellulose kumawonetsa thixotropy ngakhale pansi pa kutentha kwa gel. Katunduyu ndi phindu lalikulu pakusintha kwa malo opangira matope omanga. Iyenera kufotokozedwa pano kuti kukwera kwa ethel ethel ethel ether, mamasukidwe abwinowo, koma okwera kwambiri olemera kwambiri, ndipo amachepetsa mosiyanasiyana, omwe ali ndi mavuto ake pazachilengedwe komanso zomanga. Maonekedwe ake, zoonekeratu kuti zimakula kwambiri patavala matope, koma siyofanana. Ena mwapakatikati komanso otsika, koma ma celluse osinthidwa ali ndi magwiridwe antchito abwino pokonzanso mphamvu ya matope onyowa. Ndi kuwonjezeka kwa mafakiti, kusungira kwamadzi kwa ethel ethel.
