Uyini umphumela we-HPMC kwizakhiwo zodaka emazingeni okushisa ahlukene?

Ukugcinwa kwamanzi: I-HPMC, njenge-ejenti yokugcinwa kwamanzi, ingavimba ukuhwamuka ngokweqile kanye nokulahleka kwamanzi ngesikhathi senqubo yokwelapha. Izinguquko zokushisa zithinta kakhulu ukugcinwa kwamanzi kwe-HPMC. Ukushisa okuphezulu, okukubi kakhulu nokugcinwa kwamanzi. Uma izinga lokushisa lodaka lidlula ama-40 ° C, ukugcinwa kwamanzi kwe-HPMC kuzoba mpofu, okuzoba nomthelela omubi ekusebenzeni kodaka. Ngakho-ke, ekwakhiweni kwamazinga okushisa aphezulu, ukuze kufinyelelwe umphumela wokugcina amanzi, imikhiqizo esezingeni eliphakeme ye-HPMC idinga ukungezwa ngamanani anele ngokuya ngefomula. Ngaphandle kwalokho, izinkinga zekhwalithi ezifana ne-hydration enganele, ukuncipha kwamandla, ukuqhekeka, okuwohlokayo, nokuchitheka okubangelwa ukomisa ngokweqile kuzokwenzeka. umbuzo.

I-Bonding Properties: I-HPMC inomthelela omkhulu ekusebenzeni nasekunamathisweni kodaka. Ukunamathela okukhulu kuphumela ekumelaneni okuphezulu kwe-shear futhi kudinga amandla amakhulu ngesikhathi sokwakha, okuphumela ekusebenzeni okuncishisiwe. Mayelana nemikhiqizo ye-cellulose ether ethintekayo, i-HPMC ibonisa ukunamathela ngokulinganisela.

Ukugeleza nokusebenza: I-HPMC inganciphisa ukungezwani phakathi kwezinhlayiya, okwenza kube lula ukufaka isicelo. Lokhu kuqondisa okuthuthukile kuqinisekisa inqubo yokwakha esebenza kahle.

Ukumelana nokuqhekeka: I-HPMC yakha i-matrix eguquguqukayo ngaphakathi kodaka, yehlisa izingcindezi zangaphakathi futhi inciphisa ukuvela kokuqhekeka okushonile. Lokhu kwandisa ukuqina kokuqina kodaka, kuqinisekise imiphumela ehlala njalo.

Amandla acindezelayo futhi aguqukayo Lokhu kuzokhulisa ukumelana nezingcindezi zangaphandle futhi kuqinisekise ukuqina kwesakhiwo.

Ukusebenza okushisayo: Ukungezwa kwe-HPMC kungakhiqiza izinto ezilula futhi kunciphise isisindo. Lesi silinganiso esingesihle sisiza ekufakweni kwe-thermal futhi singanciphisa ukuqina kukagesi kokuqukethwe ngenkathi kugcinwa ukukha okungapheli kokushisa uma kungaphansi komfula wokushisa okufanayo. ubungako. The resistance to heat transfer through the panel varies with the amount of HPMC added, with the highest incorporation of the additive resulting in an increase in thermal resistance compared to the reference mixture.

Umphumela wokufaka umoya Kuphezulu futhi kunzima ukukhipha.

Ukushisa kwe-GEL: Amazinga okushisa we-gel we-HPMC abhekisela emazingeni okushisa lapho ama-molecule we-HPMC akha ijeli esikhaleni esisemanzini ngaphansi kwenani elithile lokuhlushwa kanye nenani le-pH. I-GEL lokushisa lingenye yamapharamitha abalulekile ohlelo lokusebenza lwe-HPMC, okuthinta ukusebenza kanye nomphumela we-HPMC ezinkundleni zokusebenzisa ezahlukahlukene. Izinga lokushisa le-gel le-HPMC liyanda ngokwanda kokuhlushwa. Ukwanda kwesisindo se-molecular kanye nokwehla kwesilinganiso sokufaka esikhundleni sekuzokwenza futhi izinga lokushisa le-gel ukwanda.

I-HPMC inomthelela omkhulu kwizakhiwo zodaka emazingeni okushisa ahlukahlukene. Le miphumela ihilela ukugcinwa kwamanzi, ukusebenza kwamandla, ukumelana, ukumelana kwamandla, amandla okuqhekeka, amandla acindezelayo, amandla aguqukayo, ukusebenza kwe-armal kanye nokufakwa komoya. . Ngokulawula ngokweqiniso umthamo kanye nemibandela yokwakha ye-HPMC, ukusebenza kodaka kungalungiselelwe futhi ukuqina kwalo nokuqina kwawo emazingeni okushisa ahlukahlukene kungathuthukiswa.
