Cellulose etherIli ndi chinsinsi cha madzi abwino, chomwe chingalepheretse chinyontho mu matope onyowa kuchokera panja kapena kulowerera ndi matope osanjikiza ndi matope opangidwa ndi madzi kapena matope 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, mamasukidwe apamwamba a ethel ether, ma virus abwino kwambiri osinthika, koma ngati chidwi chikhala chokulirapo, chimasokoneza madzi ndi kugwiritsidwa ntchito kwa mpeni (monga kuthira mpeni wopatulika). 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; Ma cellulose ether nthawi zambiri nthawi zambiri amadzimadzi amadzimadzi owonda, ocheperako pakuyesa kwa matope, omwe ndi opindulitsa pakupanga matope, kotero kuti matope atha kukhala ogwira mtima komanso ogwirira nthawi yomweyo; 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. Ikufunika kufotokozedwa pano kuti kukwera kwa magazi kwa cellulose, koma mamasukidwe apamwamba kwambiri, omwe amakhala ndi vuto lofanana ndi matope ake komanso omanga. 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.
