Hydroxypypyl methylcellulose (hpmc) ndi malo osinthana osinthasintha omwe amagwiritsidwa ntchito pamafakitale osiyanasiyana. Pomanga zomanga za mankhwala, chakudya chodzola, hpmc chimapeza ntchito yake m'malo osiyanasiyana.
1. Kupanga kwamankhwala ndi kapangidwe kake
HPMC ndi chopanga chopanga, chosasangalatsa, ndi polymer osungunuka madzi kuchokera ku cellulose. Mwachilengedwe, imapangidwa ndi kholo loyambira la cellose m'malo mwa methoxy (-och3) ndi hydroxypropyl (-och2ch (OCH2CH (OCH) Magulu. Mlingo wambiri wa magulu awa amatsimikizira kuti katundu ndi magwiridwe antchito a HPMC. Cholowa m'malo chimawonjezera kusungunuka kwamadzi ndi mawonekedwe ena, kupangitsa kuti ikhale yoyenera kugwiritsa ntchito mitundu yosiyanasiyana.
2. Zachilengedwe
Chimodzi mwazifukwa zazikulu zogwiritsira ntchito HPMC yabodza muzomwe zimachitika. Mayankho a HPMC amawonetsa machitidwe omwe sanali ku Newtonian, akuwonetsa mawonekedwe a pseudoplastic kapena shear. Izi zikutanthauza kuti ma virucked amachepetsa ndikuwonjezeka kuchuluka kwa chimbudzi, kulola kugwiritsa ntchito mosavuta ndi kukonzanso. Khalidwe lachipembedzo lotereli makamaka limakhala lopindulitsa kwambiri ngati kumanga kwa mafakitale, komwe kumagwiritsidwa ntchito ngati wothandizila ku Cememention mu zinthu, kumathandizira kusanja bwino komanso kuchepetsa kusamba.
3. Kusungidwa kwamadzi
HPMC imakhala ndi mwayi wamadzi ambiri chifukwa cha hydrophilic. Katunduyu ndi wofunikira pakugwiritsa ntchito pomwe kuwongolera chinyezi ndikofunikira, monga mankhusu ndi mafola. Pochotsa madzi mkati mwa matrix, hpmc zimawonetsetsa moyenera hydration ya simenti tinthu, chifukwa chokweza mphamvu, kuchepa kwa shribhlity yomaliza.
4. Mapangidwe a filimu
Kuphatikiza pa gawo lake monga wothandizira komanso wosunga madzi, hpmc amatha kupanga mafilimu owoneka bwino komanso osinthika akauma. Katunduyu amapeza zofunikira m'mafakitale ndi zodzoladzola, komwe hpmc amakhala ngati othandizira mafilimu mu zokutira za mafilimu, matrict-amasulidwa. Kutha kwa makanema kwa HPMC kumathandizira kukopeka, chitetezo, komanso kumasulidwa kwa zinthu zogwira ntchito pazinthu zotere.
5. Ngongole ndi zomatira
HPMC imagwiritsidwa ntchito kwambiri ngati binder ndi zomatira pazosiyanasiyana. Mu mankhwala opangira mankhwala, imagwira ntchito ngati balage mu piritsi, yothandizira pakupanga ufa mu mapiritsi a alaeve. Zosangalatsa zake zimathandizira tinthu omanga, ndikuonetsetsa kuti pidakhala ziwonetsero komanso ziganizo. Mofananamo, m'makampani omanga, HPMC imagwira ngati chomangira matope ndi gypsum malingana ndi gypsum, kukonza zomatira ku magawo magawo ndikupewa tsankho.
6. Kumasulidwa
Kutha kwa hpmc kuti muchepetse kumasulidwa kwa zosankha zogwira kumapangitsa kukhala kotetezeka mu mawonekedwe a malimidwecal ndi ulimi. Mwa kusintha kwa polymer ndende, kulemera kwa maselo, ndi kuchuluka kwa kulowetsa mankhwalawa, kumasulidwa kwa mankhwala osokoneza bongo kapena zigawenga zimatha kuvomerezedwa kuti mukwaniritse zochizira kapena zolimbitsa thupi. Njira yoyendetsedwa iyi imapangitsa kuti nthawi yayitali ikhale yocheperako, idachepetsa dringquemency, ndikuwongolera bwino za mankhwala ogwirizira.
7.. Kukhazikika komanso kugwirizana
HPMC imawonetsa bwino kwambiri komanso kuphatikizidwa ndi zosakaniza zina zomwe zimagwiritsidwa ntchito poyerekeza. Ndi njira ya mankhwala, osakhala ionic, komanso ogwirizana ndi zinthu zonse zachilengedwe komanso zodziwika bwino. Izi zimapangitsa kuti zisankho zomwe amakonda zimafuna njira zokhazikika komanso zosangalatsa za mankhwala ogulitsa, zinthu zina, zinthu zaumwini, komanso kugwiritsa ntchito mafakitale.
8. Kuvomerezedwa ndi Reflatory
Chofunikanso chomwe chimayendetsa ntchito yofala kwa HPMC ndi chovomerezeka chake ndi kuvomerezedwa ndi zovomerezeka pamapulogalamu osiyanasiyana. HPMC imawonedwa ngati otetezeka (glas) ndi olamulira monga chakudya cha US chakudya ndi mankhwala osokoneza bongo (FDA) ndi olamulira a ku European 50 (Efsa). Sikuti si zowawa, zosakwiyitsa, komanso zopanda pake, zomwe zimapangitsa kuti zizigwiritsa ntchito pakamwa, zapamwamba za mankhwala, komanso zakudya ndi zinthu zodzikongoletsera.
9. Kusiyanitsa
Mwinanso chimodzi mwazifukwa zomveka zodziwika bwino za HPMC ndichabe. Mitundu yake yosiyanasiyana imapangitsa kuti igwiritsidwe ntchito mafakitale ndi ntchito zingapo. Kusamutsa mawu a rheology kwa zokutira zamafakitale kuti apititse patsogolo magwiridwe a skincare on, hpmc amapereka mayankho ku misala yovuta. Kusintha kwake kwa kusinthasintha kosiyanasiyana komanso kuphatikizidwa ndi zosakaniza zosiyanasiyana zimapangitsa kuti zisankho zomwe mungakonde zimafunira zowonjezera komanso zowonjezera zowonjezera.
Hydroxypypyl methylcellulose (hpmc) ndi policemer yoyipitsa yomwe ili ndi police yomwe imagwiritsidwa ntchito pophatikiza malo osiyanasiyana komanso kugwiritsa ntchito bwino ntchito. Kuchokera pamapindu ake azomanga m'magulu ake opangidwa ndi mafilimu mu zokutira zopangira mankhwala, hpmc amakhala ngati zowonjezera zowonjezera m'mafakitale osiyanasiyana. Chitetezo chake, kukhazikika, komanso kuphatikizika kumalimbikitsanso momwe amasankhidwira padziko lonse lapansi. Monga momwe ukadaulo umayendera ndi ntchito zatsopano zimatuluka, tanthauzo la hpmc likuyembekezeka kupitiriza kukula, kudziyendetsa bwino ndi kupambana muzogulitsa magawo osiyanasiyana.
