Hydroxypypyl methylcellulose (hpmc yafupikitsa) ndi poleclar molder polymer wogwiritsidwa ntchito kwambiri wogwiritsidwa ntchito kwambiri m'mafashoni osiyanasiyana komanso tsiku lililonse. Pamasamba a zofiirira, ndipo pang'onopang'ono HPMC yawonjezera zowonjezera pazomwe zimachitika.
1. Zoyambira za HPMC
HPMC ndi ma cellulose omwe sialic ether opangidwa kuchokera ku cellulose yachilengedwe pogwiritsa ntchito mankhwala. Ili ndi mfundo zotsatirazi:
Kusungunuka kwamadzi: HPMC imatha kusungunuka m'madzi ozizira ndi madzi otentha kuti apange mawonekedwe osinthira ma viscous.
Kukhazikika: Imakhazikika mu acidic kapena alkaline media, osagwirizana ndi kusintha kwa kutentha, ndipo kumakhala ndi pokana kutentha ndi kuzizira.
Kukula: HPMC ili ndi mphamvu yabwino, imatha kuwonjezera mawidwe a dongosolo lamadzimadzi, ndipo sizophweka kusagwirizana.
Kupanga filimu: hpmc imatha kupanga kanema yunifolomu pamwamba kuti ipereke chitetezo ndi kudzipatula.
Ndi mikhalidwe iyi yomwe imapangitsa kuti kugwiritsa ntchito HPMC ku PHMC ku Pugents kuli ndi kuthekera kwakukulu komanso kwamtengo wapatali.
2. Udindo wa HPMC mu zotchinga
M'malo otetezedwa, ntchito zazikulu za HPMC zimaphatikizapo kukula, kukhazikika, kuyimitsidwa, ndi mapangidwe filimu. Ntchito zina ndi izi:
Think
Zoyeretsa nthawi zambiri zimafunikira kusungitsa mawonekedwe ena kuti apititse patsogolo zomwe wagwiritsa ntchito. HPMC imatha kupanga mawonekedwe okhazikika pophatikiza ndi madzi kuti muwonjezere mawonekedwe a zotsekemera. Kwa zonunkhira zamadzimadzi, mawonekedwe oyenera amatha kuletsa kuyenda kwambiri, kupangitsa kuti malonda azitha kuwongolera ndi kugawa mukamagwiritsidwa ntchito. Kuphatikiza apo, kukula kwake kumathandizanso kukonza zowonongekazo, kumapangitsa kuti ikhale yosavuta ikamagwiritsa ntchito kapena kutsanulira, komanso kubweretsa zomwe mwakumana nazo momasuka.
Woweruka
Mafuta amadzimadzi nthawi zambiri amakhala ndi okonda, zonunkhira, utoto ndi zosakaniza zina. Pakusunga kwa nthawi yayitali, zosakaniza izi zitha kupangika kapena kuwola. HPMC itha kugwiritsidwa ntchito ngati khola loletsa kupezeka kwa stratization. Imatanthawuza kapangidwe ka yunifolomu, imazungulira ndipo imagawana zinthu zosiyanasiyana, ndikukhazikitsa yunifolomu komanso kukhazikika kwakanthawi kwa chotupacho.
Kuimitsa Mtumiki
Tinthu tokhazikika (monga tinthu tating'onoting'ono kapena zina zosakira) nthawi zambiri zimawonjezeredwa kumakono. Pofuna kupewa tinthu toyambitsa matendawa kuti musunthe kapena kusokoneza mu madzi, hpmc monga kuyimilira kumatha kuyimitsa tinthu tating'onoting'ono kuti tiwonetsetse ma vanifolomu kuti muwonjezere. Izi zitha kusintha luso loyeretsa lazogulitsa ndikuwonetsetsa kuti zitha kuchita pafupipafupi nthawi iliyonse ikagwiritsidwa ntchito.
Wothandizira makanema
Kapangidwe ka kama filimuyo kwa HPMC kumapangitsa kuti ikhale yapadera m'malo ena apadera. Mwachitsanzo. Kanemayu amathanso kukhala ngati kudzipatula kuteteza chinthucho chifukwa cha malo akunja ndi malo akunja, potero kutaya kukhazikika kwamphamvu.
Manyowa
Pazinthu zina zotsuka, makamaka sopo wa manja kapena zinthu zosamba zomwe zimalumikizana mwachindunji ndi khungu, hpmc imakhala ndi chonyowa. Itha kuthandizira kuchepetsa kuchepa kwamadzi pakutsuka, popewa khungu lowuma. Kuphatikiza apo, zitha kubweretsanso mphamvu zodzitetezera, kupangitsa kuti khungu lifewetsa komanso bwino.
3. Kugwiritsa ntchito HPMC mu mitundu yosiyanasiyana ya zotchinga
Mafuta amadzimadzi
HPMC imagwiritsidwa ntchito kwambiri m'madzi amadzimadzi, makamaka pazopanga monga zopatsira zolerera ndi zotupa zotsuka. Itha kusintha mafayilo a zotupa ndikuwonjezera kuperekera kwa nthawi ndi zomwe zimagwiritsidwa ntchito pazogulitsa. Kuphatikiza apo, hpmc imasungunuka pang'ono m'madzi ndipo sizikhudzanso kuyeretsa.
Ma slideter ndi ma gels osamba
HPMC ilinso ngati ThundKener komanso molakwika pazinthu zachisamaliro monga ma shutirate ndi ma shals. Powonjezera mapangidwe a chinthucho, chotchinga sichophweka kufiyira manja, chikukulitsa kugwiritsidwa ntchito kwake. Kuphatikiza apo, HPMC imatha kuchepetsa kukhumudwitsa khungu ndikuteteza khungu kuti liwonongedwe ndi malo akunja.
Kuchapa ufa ndi zotchinga zolimba
Ngakhale HPMC siigwiritsa ntchito zotchinga zolimba, imatha kusewerabe yotsutsa komanso yothandizana ndi kukhazikika mumitundu inayake yotsuka. Zimatha kuteteza ufa kuchokera kuzolowera ndikuonetsetsa kuti kupezeka kwabwino mukagwiritsidwa ntchito.
Ntchito zapadera
M'mabwinja ena okhala ndi ntchito zapadera, monga antibacterial, zotchinga za phosphatete-free, etc., hpmc, monga gawo la njira yolumikizira, imatha kukulitsa mtengo wowonjezera wazomwezi. Itha kugwira ntchito ndi zosakaniza zina zogwirira ntchito kuti ziwonjezere zotsatira komanso kukhazikika kwa malonda.
4. Kukula kwa HPMC m'munda wa zotchinga
Monga zofuna za ogula chifukwa choteteza zachilengedwe ndi kuchuluka kwa thanzi, kuchuluka kwa zowonjezera kumayamba kuwongolera mobiriwira komanso mwachilengedwe. Monga zinthu zachilengedwe zachilengedwe zomwe zimachokera ku cellulose ya chilengedwe, HPMC ndi Biodegged ndipo singalemetse chilengedwe. Chifukwa chake, m'kukula kwa tsogolo la zoperewera, HPMC ikuyembekezeka kukulitsa madera ake ogwiritsa ntchito.
Ndi kupita patsogolo kwa ukadaulo wotsekemera, kapangidwe ka HPMC kumatha kuthandizidwanso ndikusinthidwa kukhala ndi zinthu zambiri zogwira ntchito. Mwachitsanzo, posintha kusinthasinthasintha kapena kutentha kapena ph, hpmc kumatha kukhalabe ndi luso labwino kwambiri.
HPMC yakhala imodzi mwazowonjezera zofunikira mu munda chifukwa cha zotchinga bwino chifukwa cha kuchuluka kwake kwa thupi ndi mphamvu monga kukula, kukhazikika, mapangidwe a filimu, ndi kuyimitsidwa. Sizongowonjezera ntchito zokhumudwitsa, komanso zimaperekanso zinthu zolimba komanso zogwira ntchito. M'tsogolomu, popita patsogolo kwa sayansi ndi ukadaulo, mwayi wokhudza kugwiritsa ntchito HPMC m'matulidwe angakhale owonjezera, ndipo kumabweretsa njira zatsopano zopangira malonda.
