Hydroxypropyl methylcellulose (hpmc) ndi etheelese, ma cellulose osungunuka ndi madzi omwe amagwiritsidwa ntchito mosiyanasiyana pamafakitale osiyanasiyana chifukwa cha mitundu yake yachinyengo. Polymer uyu amachokera ku cellulose, kudzera mu kusintha kwachilengedwe, pogwiritsa ntchito mankhwala okhudzana ndi methylation ndi hydroxypropropropropropropropropropy. Zotsatira za HPMC zimawonetsa kuphatikiza kwa katundu kuchokera m'malo mwake, ndikupangitsa kukhala chophatikizika kwambiri mu kapangidwe kake.
Zochita za HPMC
1. Maonekedwe ndi geletion:
HPMC imadziwika bwino chifukwa cha kuthekera kwake kupanga mayankho a viscous m'madzi, ngakhale pamadzi otsika. Makutu a HPMC mayankho a HPMC amatengera zinthu zingapo, kuphatikizapo kunenepa, kupsinjika, kutentha kwa mitundu ya methyl ndi hydroxypyl. Nthawi zambiri, zolemera zapamwamba komanso zochulukira zimabweretsa ma viscosies apamwamba. Chimodzi mwazinthu zodabwitsa za HPMC ndi miyeso yake yosinthira. Mukamatenthetsa, kusintha kwa HPMC kumangosintha kuchokera ku sol (madzi) ku gel (yolimba). Izi geletion imasinthika, ndi gel osamukira ku Sol State pozizira. Katundu wapaderawu ndi wofunika kwambiri pantchito zofunika kutentha.
2.
Mayankho a HPMC amawonetsa khalidwe la shear-misozi, kutanthauza kuti ma viscy awo amachepetsa ndikuwonjezeka. Khalidwe losagwirizana ndi latsopanoli ndi lopindulitsa pakugwiritsa ntchito komwe mukugwiritsa ntchito ndi kukhazikika pansi pa malo okhazikika. Kuphatikiza apo, HPMC imawonetsa Thixotropy, komwe akuwoneka pang'onopang'ono amachepetsa nthawi momata koma amachichotsa pomwe mbewa imachotsedwa. Makhalidwe a zikhalidwe izi amapanga hpmc yoyenera mapangidwe omwe amafunikira kugwiritsa ntchito bwino kugwiritsa ntchito bwino.
3. Kutha kwa mafilimu:
HPMC imatha kupanga mafilimu osinthika komanso owoneka bwino, omwe ndi opindulitsa pamapulogalamu osiyanasiyana ophatikizika. Katundu wopanga mafilimuwo amapangidwa ndi kulemera kwa polymer kwa polymer ndi kukhazikika, komanso malo owuma. Makanema a HPMC nthawi zambiri amagwiritsidwa ntchito mu zokutira zamankhwala, ma CD, ndi zida zomanga chifukwa cha zomwe amateteza komanso zotchinga.
Ntchito za HPMC
1. Makampani ogulitsa mankhwala:
HPMC imagwiritsidwa ntchito kwambiri m'makampani opangira mankhwala chifukwa cha kusakhazikika kwake komanso kusakhala kootcheni. Imagwira ntchito zingapo, kuphatikizapo ngati chomangira mapiritsi, wothandizidwa ndi mankhwala omasulira mankhwala osokoneza bongo, ndi kanema wakale potembere. M'mapangidwe oletsedwa, kutulutsa kwa gel wa HPMC kumawunikira kumasulidwa kwa chakudya pakapita nthawi, kukuthandizani kusintha mankhwala osokoneza bongo komanso odekha. Kuphatikiza apo, hpmc imagwiritsidwa ntchito ngati wothandizila kukula kwapamwamba, kupereka ndalama zofunidwa komanso kukhazikika.
2. Makampani azakudya:
Mu makampani ogulitsa zakudya, hpmc imagwiritsidwa ntchito ngati thickener, emulsifier, ndi kukhazikika. Zimakhala bwino kapangidwe ndi kukhazikika kwa zakudya zosiyanasiyana, kuphatikizapo msuzi, mavalidwe, ndi zinthu zophika. Mphamvu ya HPMC yopanga ma gels ndi mafilimu ndizothandiza kwambiri kuphika kwa gluten, komwe kumatsata ma visaloectic a gluten, potengera kuchuluka kwa malonda ndi voliyumu yomaliza. Kuphatikiza apo, hpmc imatha kukulitsa alulu-moyo ndi chinyezi chosungira cha zakudya.
3. Makampani omanga:
HPMC imagwiritsidwa ntchito kwambiri m'makampani omanga, makamaka pazogulitsa ndi zokutira. Imagwira ntchito ngati woyang'anira madzi, kukonza kugwirira ntchito ndi kutsatira zinthu za Cemion. M'masamba a tile, hpmc amathandizira nthawi yotseguka komanso kulimba mtima, kuonetsetsa kuti mugwiritse ntchito bwino. Mphamvu zake zimathandizanso kuti ntchito yotsutsa zigawenga ndi kubwereketsa, kutsogolera kusalala komanso kugwiritsa ntchito.
4.. Zosasamalira patokha:
HPMC ndi chofunikira kwambiri pamalonda osiyanasiyana, kuphatikiza shampoos, zoyesedwa, zodzola, ndi zowawa. Imagwira ngati thickener, emulsifier, ndi okhazikika, ndikupereka mawonekedwe ofunikira ndi kapangidwe kake koyambitsa. M'malonda osamalira tsitsi, hpmc amathandizira kukhazikika kwa thovu ndipo amangomva bwino. Mphamvu yake yopanga mafilimu imagwiritsidwanso ntchito pazinthu zosamalira khungu kuti mupange zotchinga zoteteza ndikuwonjezera chinyezi.
5. Utoto ndi zokutira:
Mu utoto ndi mabizinesi okutira, hpmc imagwiritsidwa ntchito ngati Rhelogy Monifier kuti muchepetse kuyenda ndikugwiritsa ntchito katundu wa utoto wamadzi. Ikufuna kufalikira kwa pignommenti, kumalepheretsa kusaka, ndikuwonjezera kukhazikika kwa mawonekedwe a utoto. HPMC imathandizanso kubuula komanso kuwongolera utoto, zomwe zimapangitsa kuti zisame.
6. Mafakitale ndi mafuta:
HPMC imagwiritsidwa ntchito m'mafakitale a mafuta ndi gasi ngati chowonjezera chakumwa chamadzimadzi. Katundu wake wosinthika amathandizira kukhazikitsa mabowo amadzimadzi, kutaya kwamadzi, ndikusintha madulidwe. Madzi opangidwanso ndi HPMC amaperekanso mafuta, kuchepetsa kukangana ndikuvala zida zobowola.
Hydroxypylferose (HPMC) ndi polymer yosiyanasiyana yokhala ndi mapulogalamu osiyanasiyana chifukwa cha zinthu zake zapadera chifukwa cha zovuta zake. Kutha kwake kupanga mayankho a viscous, onetsani kuwoneka ngati shear-mikangano ndi thixotropic, ndipo pangani mafilimu osinthika kumapangitsa kuti ikhale yothandiza kwambiri pamakampani osiyanasiyana. Mu mankhwala opangira mankhwala, imalimbikitsa kutumiza mankhwala osokoneza bongo komanso kukhazikika kwa mankhwala. M'makampani azakudya, zimawongolera mawonekedwe ndi chinyezi. Pomanga, imalimbikitsa kugwiritsidwa ntchito komanso kulimba kwa zinthu. Zochita zachisamaliro zimapindulitsa chifukwa chodzaza komanso zolimbitsa thupi, pomwe utoto ndi makampani opangira zilonda amagwiritsa ntchito kuthekera kosintha kwa rheogy. Ngakhale mu gawo la mafuta ndi gasi, katundu wa HPMC amathandizira kuyendetsa madzimadzi. Chikhalidwe cha magawo a mulpmc chikupitiliza kuyendetsanso zatsopano, ndikuwonetsa kufunika kwake ngati chofunikira kwambiri pakupanga kwamakono.
