HPMC (hydroxypropyl methylcellulose) ndi nkhani yopezeka kwambiri pomanga, mankhwala opangira mankhwala, chakudya, zodzoladzola ndi minda ina. Monga etherse yopepuka, HPMC ili ndi kusungunuka bwino, kukulira, mawonekedwe a filimu ndi zomatira ndipo motero amapangidwa m'mitundu yosiyanasiyana kuti agwirizane ndi zosowa zosiyanasiyana.
1. Gulu la mafayilo
HPMC imapezeka m'mitundu yosiyanasiyana ndipo nthawi zambiri imafotokozedwa monga mawonekedwe a 2% am'madzi am'madzi mu MPPII (masekondi a Millipascal). Malinga ndi ma vinya osiyanasiyana, hpmc imatha kugawidwa m'mitundu yotsika, yapakatikati komanso yayitali.
Kutsitsa kotsika HPMC: IscKe Lotsika HPMC imagwiritsidwa ntchito makamaka pamapulogalamu omwe amafunikira madzi abwino komanso kusokonekera, monga jakisoni wa mankhwala ndi zakudya zina zowonjezera. Zimasintha mafano a yankho popanda kukulitsa mafayilo amadzimadzi.
Sipakuda vpmc: of mavis contcton hpmc nthawi zambiri amagwiritsidwa ntchito pomanga, zokutira ndi zodzoladzola. Itha kupereka kukula koyenera, kumawonjezera chotsatsa cham'mimba ndi katundu wa makanema, pomwe akusunga madzi.
Kukwera kwambiri hpmc: kutalika kwa Visct HPMC nthawi zambiri imagwiritsidwa ntchito pazogwiritsa ntchito zomwe zimafunikira kukula ndi kukhazikika, monga mafoni omasulira mapiritsi ndi mafoni omanga. Imatha kuwonjezera mafayilo a makina otsika kwambiri ndikupanga ma gels okhazikika kapena mafilimu.
2. Gulu logawidwa ndi digirii
Mankhwala a HPMC amagwirizana kwambiri ndi digirii yawo, yomwe ndi chiwerengero cha hydroxypropyl ndi methyl m'malo mwa gawo la glucose. Madigirigi osiyanasiyana a kuloweza zinthu amakhudza kusungunuka, kutentha kutentha, ndi kagwiritsidwe kake ka HPMC.
Kukhazikika kwa HPMC: HPMC yotsika nthawi zambiri imawonetsa kutentha kwambiri ndipo ili ndi kusungunuka kosungunuka bwino pamatenthedwe otsika. Mtunduwu nthawi zambiri umagwiritsidwa ntchito pakugwiritsa ntchito zinthu zothandizira kutentha, monga mapangidwe apadera apadera mu mafakitale a mankhwala ndi chakudya.
HPMC yokhala ndi digiri yapakatikati: hpmc yokhala ndi digiri yolowera imakhala ndi zinthu zambiri ndipo zimagwiritsidwa ntchito kwambiri pomanga, zopangira ndi zodzola. Kutentha kwawo kwa gel ndi kusungunuka kumakhala koyenera, kulola kuti zisasunthire m'malo osiyanasiyana.
HPMC yolowera HPMC: Kukhazikika kwa HPMC ili ndi kutentha kotsika kwa gel ndipo kumatha kupanga ma gels kapena mafilimu pamatenthedwe otsika. Mtundu wamtunduwu umagwiritsidwa ntchito pazogwiritsa ntchito zomwe zimafuna kupanga gel gel kapena filimu yotentha kapena kutentha kwa ma copsmaumical capsule.
3. Kugawidwa ndi kusungunuka
Kusungunuka kwa HPMC kumakhudzidwa ndi mtundu wake wophatikizika ndi kunenepa kwambiri, ndipo amatha kugawidwa m'madzi ozizira komanso mtundu wamadzi otentha.
Madzi ozizira a HPMC: mtundu uwu wa HPMC umasungunuka msanga m'madzi ozizira kuti apange yankho lomwe nthawi zambiri limagwiritsidwa ntchito pa utoto, ma glues ndi zida zomangira kuti apereke zotsatira za kukula msanga.
HPMC yamadzi yosungunuka: mtundu uwu wa hpmc umayenera kusungunuka m'madzi otentha, ndipo yankho lidzapangika chowongolera pambuyo pozizira. Nthawi zambiri amagwiritsidwa ntchito m'malo omwe amafuna kukhazikika kwa matenthedwe, monga zokutira zamatenthedwe otenthetsera kapena chakudya.
4. Kugawidwa ndi madera ogwiritsira ntchito
Malinga ndi magawo ena ofunsira, HPMC imatha kugawidwanso m'mitundu yosiyanasiyana monga yomanga, mankhwala opangidwa, chakudya ndi zodzola.
HPMC yomanga: Njati yomanga, hpmc imagwiritsidwa ntchito kwambiri matope a simenti, putty ufa, zinthu zamagetsi ndi zomata za gypsum. Zimatha kusintha kusungidwa kwamadzi, kukana kutsutsana ndi ntchito, pomwe kukonza malo atamanga.
HPMC ya mankhwala ogwiritsira ntchito mankhwala: hpmc omwe amagwiritsidwa ntchito m'makampani ogulitsa pamasewera amafunikira chiyero chachikulu, chosavulaza komanso chopanda vuto, ndipo nthawi zambiri chimagwiritsidwa ntchito ngati mapiritsi a mapiritsi. Itha kusintha kumasulidwa kwa mankhwala osokoneza bongo komanso kukonza bata.
Chakudya cha HPMC: Chakudya cha chakudya cha HPMC chimafunika kutsatira zinthu zowonjezera za chakudya ndipo nthawi zambiri amagwiritsidwa ntchito ngati otsamira, emulsifiers ndi okhazikika ndi okhazikika mu chakudya. Itha kukonza kukoma, kukhazikika ndi moyo wa alumali wa chakudya, ndipo ali ndi bata.
HPMC ya zodzikongoletsera: Mu zodzikongoletsera, hpmc imagwiritsidwa ntchito ngati thickener, emulsifier ndi othandizira filimu mu zinthu zosamalira khungu, shampoos, shals shals ndi zinthu zina. Zimatha kusintha mawilo, kukhazikika ndikugwiritsa ntchito kumverera kwa chinthucho, ngakhale kukhala odekha komanso osakwiyitsa khungu.
5. Gulu la Ntchito Zapadera
Kuphatikiza pa zomwe zidalipo pamwambapa, HPMC imatha kupangidwanso ndi katundu wapadera malinga ndi zofunikira zina, monga mtundu wa madzi oyendetsa, mtundu wotsika phulusa, etc.
Wopanda madzi HPMC: Mtundu uwu wa HPMC umagwiritsidwa ntchito ngati wopangira madzi pomanga ndi zokutira kuti athetse madzi ndi kuthana ndi nyengo ndikuthana ndi moyo wake.
Kutentha Kwambiri hpmc: Kutentha kwambiri kutentha kosagwirizana ndi HPMC kungagwiritsidwe ntchito kukhalabe osakhazikika mumitundu ina ya mafakitale ndi zida zomangira zomangira.
HPMC yotsika: Mtundu uwu wa HPMC umayenera makamaka pakugwiritsa ntchito zomwe zimafunikira chiyero chapamwamba, monga chowonjezera cha mankhwala ndi zakudya zowonjezera, ndipo zimachepetsa phulusa.
Kusiyanasiyana kwa HPMC kumathandizira kuti zisinthidwe ku zofunikira zosiyanasiyana zamakampani. Mwa kusintha mafayilo ake, kuchuluka kwa kuloweza ndi kusandulika, hpmc imatha kupangidwa kuti ipange zinthu zofunikira pakupanga mitundu, mankhwala, zodzoladzola ndi minda ina.
