Hydroxypropyll methylcellulose (hpmc) ndi cellulose yopanda inic ether et ether ether ether ether ether ether ether ether ether ether kuchokera ku cellose yachilengedwe ya polymer kudzera njira zingapo zamankhwala. Ndiwo ufa wopanda mafuta, wopanda tanthauzo komanso wopanda thupi womwe umatupa mu colloidal yankho lomveka bwino m'madzi ozizira. Ikukulitsa, kumanga, kubalalitsa, ndikubalalitsa, kupanga filimu, kuyimitsa, kukhazikika, kufinya katundu wa colloid. Hydroxypylropyl ndi methyllulose ingagwiritsidwe ntchito pomanga zida zomangira, zopanga zamakaimwa, zamalonda, mankhwala, chakudya chamadzulo chimakhala.
Mankhwala a Forcemula:
Hydroxypropylmethylcelulose (c2h7o2 (o) (o) 3-mn (och3) m (och2ch (oh) n] n] n] n] n] n] n] n] n] n] n] n] n] n] n] n] n] n] nth
Kugwiritsa ntchito kwakukulu kwa hydroxypypyl methylcellulose hpmc mu zomanga:
1.
⑴ Sonyezani Kuchulukitsa Umodzi, pangani Kukhala kosavuta ku Tywewer, kusintha kusanja kosalimba, kuwonjezera madzi ndi kuponderezedwa, ndikusintha luso.
⑵ Kusunga kwamadzi kwakukulu, kutalikirana nthawi yosungirako matope, kukonza bwino ntchito, ndikuwongolera hydration ndi kulimbikitsa matope kuti apange mphamvu zamagetsi.
⑶ Onetsetsani mawu oyamba a mpweya kuti muchotse ming'alu pachimbudzi ndikupanga mawonekedwe osalala.
1..
⑴ Sonyezani Kuchulukitsa Umodzi, pangani Kukhala kosavuta ku Tywewer, kusintha kusanja kosalimba, kuwonjezera madzi ndi kuponderezedwa, ndikusintha luso.
⑵ Kusunga kwamadzi kwakukulu, kutalikirana nthawi yosungirako matope, kukonza bwino ntchito, ndikuwongolera hydration ndi kulimbikitsa matope kuti apange mphamvu zamagetsi.
⑶ Uningoletsani kusasintha kwa matope kuti apange chitoliro choyenera.
3. Matope matope
⑴ Sonkhanitsani kutsatira pamodzi ndi zomangamanga, kupititsa patsogolo madzi, ndikusintha mphamvu yamatope.
⑵ Sinthani mafuta ndi chipilala, ndikusintha zomanga; Matope adangolenzedwa ndi cellulose ether ndiosavuta kumanga, amasunga nthawi yomanga ndikuchepetsa mtengo womanga.
⑶ Madzi okwanira ma cellulose, cellulose, yoyenera njerwa zopatsa madzi.
4. Nambala yolumikizira
Kusunga kwamadzi kwa madzi, kutalikitsa nthawi yotseguka ndikusintha luso. Mafuta owoneka bwino, osavuta kusakaniza. ⑵ Sinthani kukana kwa shrinkage komanso kukana kutsutsana, sinthani bwino. ⑶ Sinthani cholumikizira cha ubalewo ndikupereka mawonekedwe osalala komanso osalala.
5. Pofika poyambira nthawi yotseguka, kulimba kwa nsalu kumatha kukhala koyenera komanso kosangalatsa kwambiri.
6. Zovala zodzichepetsera ⑴ zimapereka mafayilo ndipo imatha kugwiritsidwa ntchito ngati zowonjezera zotsutsa. Kusinthanso kwamadzimadzi ndikusintha mphamvu yakuchotsa pansi. ⑶ Kusungidwa kwamadzi komanso njira yochepetsera, kuchepetsa ming'alu ndi shrinka bii.
7.. Kukhazikika kwakukulu kwachilengedwe, kuyerekezera bwino ndi zigawo zina. ⑵ Sinthani zakumwa zonse, perekani mankhwala otsutsa, osakanizidwa ndi katundu, ndikuwonetsetsa kuti maliza.
8. Iperekeni mphamvu yayikulu.
9. ⑵ Sanjani mphamvu zobiriwira, kulimbikitsa maberete ndikuchiritsa zotsatira, ndikuwonjezera zipatso.
. , ndi ming'alu yoyambitsidwa ndi kuyanika. HPMC ilinso ndi mphamvu inayake ya mpweya. Zogulitsa za HPMC zomwe zimagwiritsidwa ntchito mwatakhala ndi kuchuluka kwa mpweya wabwino, yunifolomu ndi thovu ndi yaying'ono mpweya, zomwe zimatha kusintha mphamvu ndi matope osakanikirana. Zogulitsa za HPMC zomwe zimagwiritsidwa ntchito mwayiko zosakanizika zili ndi zotsatira zina zobwezeretsa, zomwe zimatha kutalikitsa nthawi yotseguka, yomwe imatha kuyamwa potseguka matope osakanikirana ndikuchepetsa zovuta zomanga.
