Kapangidwe ka filimu ya mafakitale - kalasi hydroxypypyl methylcellulose (hpmc) ndi gawo lofunikira pakugwiritsa ntchito gawo lalikulu lofunsira. HPMC ndi ma cellulose osungunuka m'madzi omwe amagwiritsidwa ntchito kwambiri pamakampani. Katundu wake wamakanema amakhudza mphamvu zamakina, zowoneka bwino, kukhazikika kwamankhwala, kuyerekezera ndi zosakaniza zina, ndi zina zambiri.
1. Makina opanga mafilimu
HPMC imasungunuka m'madzi kuti apange yankho la colloidal. Madziwo atatuluka, mamolekyu a HPMC atatha kukonzanso ndikulumikizana wina ndi mnzake kuti apange filimu yopitilira muyeso ndi mphamvu zina komanso kulimba. Kukhalapo kwa hydroxypropyl (-ch2choch3) ndi methyl (-ch3) magulu a HPMC
2. Katundu wamakina
Mphamvu ndi Underlity
Mafilimu a HPMC akuwonetsa mphamvu zapamwamba komanso zowunikira ndipo zimatha kupirira zipsongo zamakina osasweka. Mphamvuzi zimakhudzana ndi kulemera kwa maselo, kuchuluka kwa zolowa m'malo mwake, komanso kukhazikika kwa HPMC yankho. HPMC yokhala ndi kulemera kwapamwamba kwambiri komanso kuchuluka kwazolowa m'malo mwamphamvu komanso mafilimu okhoma. Izi zimapangitsa kuti hpmc zamtengo wapatali pazogwiritsidwa ntchito zomwe zimafunikira mphamvu zapamwamba kwambiri, monga zopangira, zokutira, ndi mapiritsi opangira mankhwala.
Chosangalatsa
Makanema a HPMC ali ndi zomatira bwino ndipo amatha kutsatira mitundu yosiyanasiyana yosiyanasiyana, monga mapepala, chitsulo, galasi, galasi, ndi pulasitiki. Katunduyu amazigwiritsa ntchito kwambiri pobatiza ndi zomatira. Kutsatsa kumakhudzidwanso ndi njira yokhazikika komanso yowuma.
3. Katundu wamaso
Makanema a HPMC nthawi zambiri amawonekera kapena kuwonekera bwino komanso amakhala ndi zinthu zabwino kwambiri. Kukongola kwa mafilimuwa kumadalira makamaka kufanana kwa yankho, malo owuma, ndi kuchuluka kwa thovu lomwe lingawonekere panthawi yomwe amapanga filimuyo. Kuwonekera kwakukulu kumapangitsa kuti HPMC yothandiza kwambiri pazinthu zomwe zimafunikira zowoneka bwino, monga chakudya chomwe chakudya chaperekera zakudya, zoperekera mankhwala, ndi zokutira zoteteza.
4. Kukhazikika kwamankhwala
Kukaniza kwa madzi
Makanema a HPMC ali ndi kuchuluka kwa madzi. Ngakhale HPMC yokha ndi yosungunuka yamadzi, kapangidwe kake ka filemation sikusungunuka mosavuta mukadzaza madzi. Katunduyu ndi wopindulitsa mu ntchito zambiri, monga kumanga, zomata, komanso zokutira zamadzi. Komabe, kukana madzi si sirature, komanso kutalika kwamadzi kumayambitsa kutupa kapena kusokonekera kwa filimuyo.
Kukaniza kwa mankhwala
Filimu ya HPMC ili ndi mankhwala abwino pamankhwala osiyanasiyana, makamaka mu acid-base malo. Izi zimapangitsa kukhala koyenera kwa malo okhalamo, monga zokutira ndi makanema oteteza mu malonda. Kukhazikika kwamankhwala kwa HPMC kumakhudzidwanso ndi kuchuluka kwake kwa matalala ndi malo omwe amagwiritsidwa ntchito.
5. Mikhalidwe yopanga filimu
Yankho kukhazikika
Njira yothetsera mavuto imakhudzanso mtundu wa mafilimu a HPMC ndi kanema wa filimuyo. Nthawi zambiri, kuchuluka kwa HPMC mayankho a HPMC amapanga ficker ndi mafilimu olimba. Komabe, kwambiri kukhazikika kwambiri kumabweretsanso mafayilo ochulukirapo pa njirayo, zimapangitsa kuti zikhale zovuta kugwiritsa ntchito.
Mikhalidwe youma
Kuthamanga ndi kutentha kumakhala ndi mphamvu pa mapangidwe ndi katundu wa filimuyo. Kutentha Kwambiri ndi kutentha kouma mwachangu nthawi zambiri kumabweretsa kukhazikitsidwa kwa thovu mufilimuyi, akukhudza kuwonekera kwa kanema komanso makina opanga filimuyo. Njira yowuma pang'onopang'ono imathandizira kupanga filimu yunifolomu, koma imatha kuchititsa kuti zikhale zosakwanira muyeso wa zosungunulira, zomwe zimakhudzanso mtundu wa filimuyo.
6. Kugwirizana ndi zosakaniza zina
Filimu ya HPMC imagwirizana bwino ndi zinthu zosiyanasiyana zowonjezera komanso zogwirira ntchito, monga ma pulasitiki, owotcha, mafinya, etc. Mwachitsanzo, kuwonjezera mawotchi osefukira kumatha kukonza kusintha kwa filimuyo, pomwe othandizira olumikizirana amatha kuwonjezera mphamvu ndi kukana madzi a filimuyo.
7. Magawo a mapulogalamu
Zipangizo Zomanga
M'mabuku omanga, mafilimu a HPMC amagwiritsidwa ntchito m'matope osakanikirana, pute, zokutira ndi zina. Mphamvu yake yopanga mafilimu imatha kukonza zotsatsa, kukana ndi kukana madzi ndi kukana kwa zinthuzo.
Mankhwala
Mu gawo la pharmaceutical, hpmc limagwiritsidwa ntchito ngati mawonekedwe ophatikizira mapiritsi opanga mankhwala. Mphamvu yake yopanga mafilimu imatha kuyendetsa kumasulidwa kwa mankhwala osokoneza bongo komanso kukonza bata komanso kutheka kugwiritsa ntchito mankhwala osokoneza bongo.
Makampani Ogulitsa Chakudya
Makanema a HPMC amagwiritsidwa ntchito ngati zida zodulira mu makampani ogulitsa zakudya ndi zotchinga bwino.
Zopindulitsa ndi Kumatira
Kutsatira ndi kuwonekera kwa mafilimu a HPMC kumawapangitsa kukhala omata zomatira ndi zomatira, ndipo amagwiritsidwa ntchito kwambiri m'mafakitale okhala ndi mafakitale.
8. Ubwenzi wachilengedwe
HPMC ndi chinthu chosinthidwa kuchokera ku cellulose wachilengedwe. Njira yake yopanga mafayilo simafunikira ma soll ovulaza ndipo ili ndi malo abwino oyenda bwino komanso ochezeka. Izi zimapangitsa kukhala tanthauzo lalikulu pakukula kwa umagwirira wobiriwira komanso zinthu zosakhazikika.
Kapangidwe ka kama filimuyo ya mafakitale - kalasi hpmc kumapangitsa kuti ikhale yovuta pakugwiritsa ntchito mitundu yosiyanasiyana. Ubwino wake mu mphamvu yamakina, malo owoneka bwino, kukhazikika kwamankhwala, komanso kulingana bwino ndi zinthu zina zomwe zimawapatsa ntchito zosiyanasiyana. Kaya zomangira, mankhwala opangira mankhwala, ma CACAAGOWS, kapena zophatikiza ndi zomatira, hpmc yawonetsa ntchito yabwino kwambiri. Ndi kupita patsogolo kwa sayansi ndi ukadaulo, ukadaulo wamafilimu ndi madera omwe amagwiritsa ntchito HPMC ipitilira kukula, kulimbikitsa kukula kwa ntchito zatsopano.
