Hpmc methoxy ndi hydroxypropoxy

HPMC (hydroxypropylmethylcelulose Amagwiritsidwanso ntchito ngati promacemicals. HPMC ndi polymer yosungunuka, yopanda madzi yomwe katundu amatha kusiyanasiyana mwa kusintha kwa kuchuluka kwa hydroxypropoxy ndi methoxy magulu.

Kupanga kwa HPMC kumaphatikizapo kusinthika kwa cellulose ndi methyl chloride ndi ma propylene oxide. Mulingo wa methoxy ndi hydroxypropoxy zogwirizira zitha kuyang'aniridwa pa nthawi yopanga, ndikukhudza zomaliza za chinthucho.

Katundu wofunika wa HPMC ndi kuthekera kwake kupanga ma gels. Ma gels a HPMC amagwiritsidwa ntchito kwambiri makampani ogulitsa zakudya monga otsatsa ndi okhazikika. Amagwiritsidwanso ntchito ngati omasulidwa mu mankhwala ogulitsa mankhwala kuti athetse kuchuluka komwe mankhwalawa amamasulidwa. Katundu wa gelc amatha kusinthidwa ndikusintha kuchuluka kwa zolowa za hydroxyprophiroxy ndi methoxy magulu a methoxy.

Katundu wina wofunika wa HPMC ndiye kupulumuka kwake. HPMC imasungunuka mosavuta m'madzi, ndikupangitsa kuti ikhale yosangalatsa. Zimagwirizananso ndi zomwe zimachitika zambiri zomwe zimagwiritsidwa ntchito m'makampani opanga mankhwala, kulola kugwiritsidwa ntchito mosavuta kwa mankhwala osokoneza bongo.

HPMC imagwiritsidwanso ntchito m'makampani omanga ngati chophimba ndi kukula muzogulitsa za simenti. Kuonjezera HPMC kwa sizedi kumapangitsa kukhala kovuta komanso kumachepetsa komanso kumachepetsa. Zimawonjezeranso zosakaniza zamadzi zosakaniza, potero ndikupititsa nthawi ndi mphamvu zonse zochiritsidwa.

Pakampani yazosasamala, hpmc imagwiritsidwa ntchito ngati thickisiner ndi kukhazikika kwa zodzola komanso zinthu zosamalira payekha. Kutha kwake kupanga mawonekedwe a gel ngati gel olimbikitsa kumapangitsa kuti ikhale yokhazikika yodzola ndikusintha mawonekedwe a mafuta ndi zotupa.

HPMC ndi zinthu zambiri zokhudzana ndi mapulogalamu osiyanasiyana m'mafakitale osiyanasiyana. Katundu wake ukhoza kupangidwa ndi kusintha kuchuluka kwa matenda a hydroxyprophiroxy ndi methoxy magulu. Amasungunuka mosavuta m'madzi, ndikupangitsa kuti akhale wowoneka bwino. Kutha kwake kupanga ma gels kumapangitsa kuti ikhale yothandiza ngati yolimbitsa thupi ndi kusungunuka mu chakudya, chisamaliro chaumwini ndi mafakitale omanga. Kuonjezera HPMC kwa sizedi kumathandizira kugwirira ntchito komanso madzi osunga madzi, kupangitsa kukhala wolimba komanso kukhala wolimba. Ponseponse, hpmc ndi zinthu zofunikira zomwe zikupitiliza kupeza ntchito zatsopano mafakitale osiyanasiyana, kukonza malonda ndi njira.
