Zomwe Zimakhudza Kusungidwa kwa Madzi kwa Cellulose ether

Kuchuluka kwa madzi a cellulose ethers, monga hydroxypropyl methyl cellulose (HPMC), hydroxyethyl cellulose (HEC), ndi carboxymethyl cellulose (CMC), kumagwira ntchito yofunika kwambiri pakugwiritsa ntchito zambiri, makamaka pazomangamanga monga matope opangidwa ndi simenti ndi ma renders. Pali zinthu zingapo zomwe zingakhudze mphamvu yosungira madzi ya cellulose ethers:

1. Kapangidwe ka Mankhwala: Kapangidwe kake ka cellulose ethers kumakhudza mphamvu yawo yosungira madzi. Zinthu monga kuchuluka kwa m'malo (DS), kulemera kwa maselo, ndi mtundu wamagulu a ether (mwachitsanzo, hydroxypropyl, hydroxyethyl, carboxymethyl) zimakhudza kuyanjana kwa polima ndi mamolekyu amadzi ndi zigawo zina mu dongosolo.
2. Degree of Substitution (DS): Madigiri apamwamba olowa m'malo nthawi zambiri amapangitsa kuti madzi achuluke. Izi zili choncho chifukwa DS yapamwamba imabweretsa magulu ambiri a hydrophilic ether pamsana wa cellulose, kupititsa patsogolo mgwirizano wa polima pamadzi.
3. Kulemera kwa Maselo: Ma cellulose ether okhala ndi mamolekyu apamwamba kwambiri amakhala ndi mphamvu zosunga madzi bwino. Unyolo wokulirapo wa polima ukhoza kumangirira bwino kwambiri, ndikupanga maukonde omwe amatsekera mamolekyu amadzi mkati mwadongosolo kwa nthawi yayitali.
4. Kukula kwa Tinthu ndi Kugawa: Muzomangamanga, monga matope ndi ma renders, kukula kwa tinthu tating'ono ndi kugawa kwa ma cellulose ether kumatha kukhudza dispersibility ndi kufanana kwawo mkati mwa masanjidwewo. Kubalalika koyenera kumatsimikizira kuyanjana kwakukulu ndi madzi ndi zigawo zina, kupititsa patsogolo kusunga madzi.
5. Kutentha ndi Chinyezi: Mikhalidwe ya chilengedwe, monga kutentha ndi chinyezi, ingakhudze khalidwe la kusunga madzi la cellulose ethers. Kutentha kwambiri ndi kutsika kwa chinyezi kungapangitse kuti madzi asamayende bwino, kuchepetsa mphamvu yosungira madzi yonse ya dongosolo.
6. Njira Yosakaniza: Njira yosakanikirana yomwe imagwiritsidwa ntchito popanga mapangidwe okhala ndi ma cellulose ethers amatha kukhudza momwe amasungira madzi. Kubalalika koyenera ndi hydration ya polima particles ndizofunikira kuti ziwonjezeke bwino posunga madzi.
7. Kugwirizana kwa Chemical: Ma cellulose ethers ayenera kukhala ogwirizana ndi zigawo zina zomwe zilipo popanga, monga simenti, aggregates, ndi admixtures. Kusagwirizana kapena kuyanjana ndi zina zowonjezera kungakhudze njira ya hydration ndipo pamapeto pake kumakhudza kusungidwa kwa madzi.
8. Kuchiritsa Mikhalidwe: Mikhalidwe yochiritsa, kuphatikiza nthawi yochiritsa ndi kutentha kwa machiritso, imatha kukhudza ma hydration ndikukula kwa mphamvu muzinthu zopangidwa ndi simenti. Kuchiritsa koyenera kumatsimikizira kusunga chinyezi chokwanira, kulimbikitsa machitidwe a hydration ndikuwongolera magwiridwe antchito onse.
9. Mulingo Wowonjezera: Kuchuluka kwa cellulose ether yowonjezeredwa ku mapangidwe kumakhudzanso kusunga madzi. Mulingo woyenera kwambiri wa mlingo uyenera kutsimikiziridwa malinga ndi zofunikira za pulogalamuyo kuti mukwaniritse zomwe mukufuna kusunga madzi popanda kusokoneza machitidwe ena.

Poganizira izi, opanga ma formula amatha kukulitsa momwe ma cellulose ether amasungira madzi m'njira zosiyanasiyana, zomwe zimapangitsa kuti zinthu zomaliza zizigwira ntchito bwino.
