Kutchuka kwa hydroxypropyll methylcellulose chidziwitso cha HPMC

Hydroxypropyll methylcellulose hpmc ndi mankhwala osagwirizana ndi ether opangidwa kuchokera ku cellulose yachilengedwe ya polymer kudzera pakusintha kwamankhwala. Ndiwo ufa wopanda mafuta, wopanda chidwi komanso wopanda chidwi womwe umatupa m'madzi ozizira kupita ku yankho lomveka bwino kapena pang'ono la colloidal. Ili ndi katundu wa kukula, kumanga, kubalalitsa, kupondaponda, kupanga mafilimu, kuyimitsa, kudzipatula, kusunga chinyezi, kukonzanso colloud ndi chinyezi. Hydroxypylrose ya methylcellulose ingagwiritsidwe ntchito pomanga zida zomangira, zopanga makampani, zopanga, mankhwala, chakudya chamasiku onse.

Kusunga kwamadzi ndi mfundo za hydroxypypyl methylcellulose hpmc

Cellulose ether hpmc makamaka amagwiritsa ntchito njira yosungira madzi ndi kukula kwa matope a simenti ndi gypsum, omwe amatha kukonza coutheon ndi kukana kwa sagn ya slurry.

Zinthu monga kutentha kwa mpweya, kutentha ndi kuthamanga kwa mphepo kumakhudza kuchuluka kwa madzi mu matope a simenti ndi gypsum. Chifukwa chake, nthawi zosiyanasiyana, pali kusiyana kwinanso m'madzi osungiramo zinthu zomwe zimapangidwa ndi HPMC yowonjezeredwa. Mu zomanga zina, kuchuluka kwa madziwo kumatha kusinthidwa ndikukulitsa kuchuluka kwa HPMC yowonjezeredwa. Kusunga kwamadzi kwa methyl cellulose ether kutentha kwambiri ndi chizindikiro chofunikira kusiyanitsa mtundu wa methyl cellulose ether. Zinthu zochulukirapo hpmc zimathetsa bwino vuto la madzi osungidwa kutentha kwambiri. Mu nyengo zotentha kwambiri, makamaka m'malo otentha ndi owuma ndi zomangamanga zowonda m'mbali mwa dzuwa, hpmc zapamwamba kwambiri zimafunikira kukonza chitetezo chamadzi cha slorry. HPMC yapamwamba kwambiri, yofanana bwino kwambiri, methoxy ndi hydroxyprovoy amagawika ma atomu am'madzi, kuti madzi aulere amathetsa madzi oyambitsidwa ndi kutentha kwanyengo komanso kukwaniritsa kusungidwa kwamadzi.

Cellulose HPMC imatha kukhala mogwirizana komanso moyenera mankhwala a simenti ndi gypsum, ndikuyika tinthu tokhazikika, ndipo zimapanga filimu yonyowa pang'onopang'ono imasulidwa pang'onopang'ono kwa nthawi yayitali. Kuchitira mankhwala onunkhira kwa zinthu zowoneka kumachitika, potero, kulimbikitsa ubale wolimba ndi kulimba mtima kwa zinthuzo. Chifukwa chake, mu kutentha Kwambiri Zimawonjezeranso zovuta zomanga antchito. Kutentha kwa kutentha kumachepa, kuchuluka kwa HPMC kumatha kuchepetsedwa pang'onopang'ono, ndipo madzi omwewo atha kukwaniritsidwa.

Kusunga kwamadzi kwa hydroxpyl methylcellulose zinthu zomwe zimakhudzidwa ndi zinthu zotsatirazi:

1. Cellulose ether hpmc homogeneity
Kuchita bwino kwa HPMC kuli ngati kufalitsa kwa methoxy ndi hydroxyprophiroxy magulu ndi kusungidwa kwamadzi kwambiri.

2. Cellulose etherc hpmc kutentha kwa gel
Kutentha kwa mafuta kwa gel osakaniza, kuchuluka kwa madzi osunga madzi; Kupanda kutero, kutsitsa madzi osunga madzi.

3. Treuluse ether hpmc
Pamene mafakidwe a HPMC amawonjezeka, kuchuluka kwa madziwo kumawonjezekanso. Mawonekedwe akafika pamlingo wina, kuwonjezeka kwa malo osungira madzi kumatenga kuti akhale odekha.

4. Cellulose ether etherc kuwonjezera
Chokulirapo chowonjezera cha cellulose ether hpmc, malo osungira madziwo ndi madzi osungitsa madzi. Mu mitundu ya 0,25-0.6%, kuchuluka kwa madzi kumawonjezera mwachangu ndi kuchuluka kwa kuchuluka kwa zowonjezera; Kuphatikiza apo kumawonjezeranso, zomwe zimachitika kuti madzi osungitsa madzi ayamba pang'onopang'ono.
