HPMC (hydroxypypyl methylcellulose) ndi cellulose yosungunuka yamadzi yomwe imagwiritsidwa ntchito kwambiri m'mafakitale ambiri monga mapangidwe opanga, mankhwala opangira mankhwala, komanso zodzoladzola. Mphamvu zake zapadera komanso zamankhwala, monga kubalangula wabwino, kupanga mafilimu, komanso ntchito ndi ntchito zapamwamba, pangani phindu lapadera mu mapangidwe osiyanasiyana. Pamunda wakuyeretsa zinthu, hpmc ngati chowonjezera chimatha kusintha choyeretsa mpaka pamlingo wina.
1. Makina a zochita za HPMC pakuyeretsa
Monga polymer pompound, hpmc makamaka imakhudza kuyeretsa motsatira njira zotsatirazi:
Zotsatira Zakulitsa: HPMC ili ndi katundu wabwino kwambiri ndipo imatha kuwonjezera mafayilo owoneka bwino. Zoyeretsa zokutira zimagwirizana mosavuta pansi kuti zitsukire, kufotokozera nthawi yolumikizana pakati pa zotsuka ndi banga. Kuchita kosatha kumeneku kumathandiza kukonza njira yotsekemerayo pakuphwanya ndikuchotsa madontho.
Ntchito yoyeserera: Pambuyo powonjezera hpmc ku formula, imatha kuyimitsa tinthu tokhazikika mu madziwo powonjezera mamasukidwe amadzimadzi, makamaka kuti athetse mphamvu yoyeretsa madontho okakamiza, makamaka omwe ndi ovuta omwe amakhala osavuta monga mchenga, mafuta, etc. Madontho.
Mapangidwe a filimu ndi mafuta: Kanema wopangidwa ndi HPMC akhoza kupanga filimu yoteteza pamwamba kuti isadetse kuipitsidwa. Izi ndizothandiza makamaka mukatsuka, moyenera kuyambiranso kukonzanso. Kuphatikiza apo, kupasuka kwa hpmc kumathandizira kuchepetsa mikangano pakati pa zida ndi mawonekedwe, kuchepetsa kuwonongeka kwa nthaka poyeretsa.
Kusungunuka ndi hydration: hpmc imasungunuka mosavuta m'madzi ndikuwonetsa luso la hydraction mu madzi, zomwe zimatha kusintha yunifolomu yobalalitsa zinthu zoyeretsa poyeretsa Sinthani kukonza mphamvu.
2. Mphamvu ya HPMC pamitundu yosiyanasiyana ya zotchinga
Oyeretsa apakhomo: Oyeretsa pakhomo, ali ndi HPMC imatha kusintha madontho a nyumba wamba monga madontho amafuta ndi fumbi kudzera mu mawonekedwe okulirapo ndi filimu. Nthawi yomweyo, mphamvu zoyimitsidwa kwa hpmc imalepheretsa madoresi kuti asabwezeretse pansi ndikukhala ndi luso lapatali.
Zoyeretsa mafakitale: pakutsuka kwa mafakitale, makamaka pankhani ya madontho olemera monga zitsulo zolemera, hpmc zitha kuthandiza zosakaniza ndikuwonjezera mawonekedwe a utu Oyera. M'mayiko opanga mafakitale, amachepetsa kutayika kowonongeka pakuyeretsa, potengera kugwiritsidwa ntchito kupulumutsa.
Zosamalira payekha chinyezi. Tetezani. Kuphatikiza apo, zinthu zofatsa za HPMC zimapangitsa kuti ikhale yopanga zinthu zomwe zimakhala ndi khungu.
3. Zotsatira zenizeni za HPMC pa kukonza bwino kuyeretsa
Ngakhale HPMC ili ndi zinthu zosiyanasiyana zomwe zingakhale zopindulitsa pakutsuka munjira yoyeretsa zomwe zimagwiritsidwa ntchito pakupanga zomwe zikuchitika zimakhudzidwa ndi zinthu zambiri zomwe zimakhudzidwa, monga zosakaniza za madontho, etc.
Kuyeretsa madontho owala: Mafuta owala, fumbi, etc. M'moyo watsiku ndi tsiku, kuwonjezera kuchuluka kwa HPMC yoyenera kuwongolera mphamvu yoyeretsa bwino. Oyeretsa okhwima amafalikira kwambiri pamadontho ndikukhalabe achangu nthawi yayitali, ndikuchotsa madontho.
Kuyeretsa madontho olimba: chifukwa cha madontho okuntho, monga mafuta ndi dothi la mafakitale, HPMC imatha kuwonjezera kulowetsedwa kwa malowo, kumapangitsa kuti zikhale zosavuta zoyeretsa kuti zizilowa mu dothi. Komabe, popeza sizikhala ndi luso lothana ndi oxidizing, hpmc pamwamboli, lizichitika motere, liyenera kugwiritsidwa ntchito molumikizana ndi zosakaniza zina zamphamvu.
Kuchita pazinthu zosiyanasiyana: Mafuta a HPMC ndi mawonekedwe opanga mafilimu amapangitsa makamaka kukhala zotetezeka, monga galasi, matamba, chikopa ndi mawonekedwe ena. Mwa kuchepetsa kukangana, kumateteza pamtunda kuchokera kuvala ndi kung'amba izi pakutsuka, kufalitsa moyo wa chinthucho.
4. Mavuto Ogwiritsa Ntchito HPMC
Ngakhale HPMC imapereka zabwino zambiri pokonza zoletsa zoletsa, palinso zovuta zina. Mwachitsanzo, mikhalidwe yapamwamba ya HPMC siyingakhale yolimbana ndi zoyeretsa zomasuka pamachitidwe ena. Kuphatikiza apo, kugwiritsa ntchito HPMC kungapangitse kuti othandizira akhalebe pansi, makamaka m'malo omwe sangadutse mosavuta atatsuka, omwe angakhudze kukonzanso. Chifukwa chake, kuchuluka kwa HPMC kumayenera kuthandizidwa malinga ndi zochitika zapadera zomwe zimapangidwa mu kapangidwe kake.
Monga chowonjezera pakutsuka pazogulitsa, HPMC imatha kusintha mphamvu yoyeretsa njira zosiyanasiyana monga kukula, kuyimitsidwa, ndi mapangidwe filimu. Imagwira ntchito kwambiri pakuwonjezera nthawi yolumikizana pakati pa zotsekemera ndi madontho, kuchepetsa mikangano, komanso kupewa madontho osatsatiranso. Komabe, HPMC si panacea ndipo kugwira ntchito kwake kumatengera kukonzanso kwazinthu zomwe zimagwiritsidwa ntchito. Chifukwa chake, kuphatikiza koyenera kwa hpmc ndi zosakaniza zina kungakwaniritse zotsatira zabwino kwambiri.
