Hydroxypropyll methylcellulose (hpmc) ndi omwe amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana pamakampani osiyanasiyana chifukwa chazinthu zake zapadera. Nkhaniyi imakhudza zovuta za HPMC, ndikufufuza kapangidwe kake, katundu, ndi kugwiritsa ntchito zosiyanasiyana. Kuchokera pa mankhwala omanga, zopangidwa ndi zakudya pazinthu zamwini, hpmc zimagwira ntchito yofunika kwambiri pakupanga makono.
Hydroxypylropyl (HPMC) ndi cellulose yosinthika yomwe imapeza kugwiritsa ntchito kwambiri m'mafakitale kuchokera ku mafakitale ogulitsa mankhwala omanga, chakudya, komanso chisamaliro chaumwini. Zosiyanasiyana zake zimapangitsa kuti zikhale zofunikira pakugwiritsa ntchito zinthu zosiyanasiyana, zimathandizira kukhazikika, kuwoneka, komanso magwiridwe antchito ambiri.
Kupanga kwa 1.chemical ndi katundu
HPMC imapangidwa kudzera mu alkali cellulose ndi methyl chloride ndi ma propylec oxide, chifukwa cha magulu a hydroxypropyl ndi methoxy magulu a methocypyl. Kusintha kumeneku kumapereka zinthu zosiyanitsa ndi HPMC, kuphatikizapo madzi kusalala, mipweya yambiri, kuthekera kwamafilimu, komanso chiwongolero chabwino cha rheagical.
Mulingo wa zolowa m'malo (DS) ndi kulemera kwa ma sicar mopititsa patsogolo katundu wa HPMC. DS Zapamwamba Zimawonjezera Kusungunuka Madzi ndikuchepetsa kutentha kwa matola, pomwe kulemera kwa ma vilus kumatha kuwoneka mafayilo ndi mawonekedwe a filimu. Zovala izi zimapangitsa HPMC Kusintha kwazinthu zosiyanasiyana.
2.Funing of HPMC
Kuwongolera ndi Rheogy: HPMC imagwira ngati wothandizila mu mayankho am'madzi, kupatsa mafakisoni ndi kukulitsa kukhazikika kwa mapangidwe. Khalidwe lake la pseudoplastic limalola kuwongolera mwachidule rhealogical rhealogical kuwongolera, kuwongolera kupanga kwa zinthu zomwe zimafunidwa.
Mapangidwe a filimu: Chifukwa cha kuthekera kwake kupanga mafilimu owonekera komanso osinthika atawuma, mapiritsi a mankhwala a mankhwala, komanso zinthu zosamalira pandekha. Makanema awa amapereka zotchinga, kusungidwa kwa chinyezi, komanso kumasulidwa koperewera.
Kusungidwa kwamadzi: M'malo opangira monga maboti, mazira, ndi zomatira, hpmc amathandizira kutaya thupi ndipo amalepheretsa kuchepa kwa madzi mwachangu pakuchiritsa. Izi zimathandizira mofuula, zimachepetsa kusokonekera, ndipo zimatsimikizira hyduction ya simential cential.
Blander ndi Distegrance: M'mapangidwe a mankhwala opangira mankhwala, HPMC imagwira ntchito ngati binder, atagwira zigawo limodzi m'mapale, makapisozi, ndi magalamu. Kuphatikiza apo, kuthekera kwake kutupa komanso kusokonekera m'matumba ogwiritsa ntchito zothandizira kumasulidwa kwa mankhwala osokoneza bongo.
Stabilifar ndi emulsifier: hpmc imakhazikika kuyimitsidwa, emulsions, ndi zikopa, zodzikongoletsera, ndi mafakitale. Imalepheretsa kulekanitsa, kumapangitsa kapangidwe ka alumali chifukwa cholepheretsa kukula ndi makutidwe.
3.Pestication ya HPMC
Mankhwala: HPMC ndi yofunika kwambiri mu mitundu yolimba ya mkamwa monga mapiritsi, makapisozi, ndi ma pellets. Udindo wake monga wowotcha, wosasuta, ndi wowongolera, amawonetsetsa bwino, chitetezo, komanso kutsata wodwala mankhwala.
Ntchito Yomanga: Mu makampani omanga, hpmc imawonjezeredwa ku zinthu za simenti kuti zithandizire kugwirira ntchito, kusungidwa kwamadzi, komanso kukhala kosangalatsa. Zimalimbikitsa mapangidwe a maboti, mazira, ma grout, ndi otembenukira, zomwe zimayambitsa kukhala olimba komanso osangalatsa.
Chakudya ndi zakumwa: hpmc imapeza ntchito pazogulitsa za chakudya ngati chitsirizidwe, chisungunuke, ndi emulsifier. Nthawi zambiri amagwiritsidwa ntchito pamitu, mavalidwe, njira zina zamkaka, ndi zinthu zophika mkate kuti zizikonza kapangidwe kake, kamwa, ndi aluma.
Kusamalidwa Kwaumwini: Mu zodzikongoletsera komanso zinthu zosamalira payekha, hpmc zimagwira ntchito ngati kanema wakale, Thupi, ndi kuyimitsa wothandizira. Ili ndi mafuta, zodzola, shampoos, ndi manoste, zopatsa chidwi.
Upatupa ndi Zovala: HPMC imagwiritsidwa ntchito mu utoto wozikidwa m'madzi, zokutira, ndi zomatira kusinthira ma visction, kusintha kukana kwa Aleg, ndikuwonjezera mapangidwe a kanema. Zimalimbikitsa kugwiritsa ntchito yunifolomu, kutsatira magawo magawo, ndipo kukhazikika kwakumaliza kumatha.
Malingaliro ndi Maganizo ndi Mavuto
Ngakhale anali kugwiritsa ntchito bwino komanso kugwiritsa ntchito zovuta monga kusintha kwa ma batch, malingaliro owongolera, ndi zovuta zachilengedwe zimapitilira kupanga ndi kugwiritsa ntchito HPMC. Zoyesayesa zamtsogolo zomwe zimafuna kuthana ndi zovuta izi pamene mukugwiritsa ntchito mapulogalamu a buku ndi njira zokhazikika pamsewu wa HPMC.
Hydroxypropyl methylcellulose (hpmc) ndi mankhwala osiyanasiyana osiyanasiyana ndi kugwiritsa ntchito mitundu yosiyanasiyana pamankhwala opanga mankhwala, zomangamanga, chakudya, magawo a mafakitale. Kuphatikiza kwake kwapadera kwa katundu, kuphatikizapo kuthira, kupanga mafilimu, kusungidwa kwamadzi, komanso kulimba mtima, kumapangitsa kuti zikhale zofunikira pakupanga zamakono. Mwa kumvetsetsa kapangidwe ka mankhwala, katundu, ndi ntchito za HPMC, mafakitale amatha kuyankha kuti kuthekera kwatsopano ndikupanga zofunikira zamagetsi zomwe zimakwaniritsa zosowa za ogula ndi misika.
