Hydroxypylferose (HPMC) ndi polim yosiyanasiyana yogwiritsidwa ntchito kwambiri m'mafakitale monga mankhwala, chakudya, ndi zomanga. Kuchita kwake kumasiyanasiyana kutengera magawo ake, omwe amasiyana pazigawo monga mawonekedwe, kuchuluka kwa kuloweza, tinthu tating'onoting'ono, komanso chiyero. Kumvetsetsa momwe mafilimu awa amakhudzira magwiridwe ntchito ndikofunikira kuti muthe kugwiritsa ntchito ntchito zosiyanasiyana.
1. Makutu
Ma Ukuwoneka ndi gawo lovuta lomwe limakhudza kwambiri magwiridwe antchito a HPMC mu ntchito zosiyanasiyana. Nthawi zambiri imayesedwa ku Centipois (CP) ndipo imatha kukhala yotsika kwambiri mpaka kwambiri.
Mankhwala opangira mankhwala: Mu mafinya, otsika-akutsitsa hpmc (mwachitsanzo, 5-50 cp) nthawi zambiri amagwiritsidwa ntchito ngati chomangira popanda kuchititsa kuti piritsi isasokonezeke. Kukwera kwambiri HPMC (mwachitsanzo, 1000-4000 cp), kumbali inayo, kumagwiritsidwa ntchito pomasulidwa. Maviyo apamwamba amachepetsa kuchuluka kwa mankhwalawa, motero kumathandizira mankhwalawa.
Ntchito Yomanga: Mumenti yochokera ku Smentan-Iscreket HPMC (mwachitsanzo, 100-200,000 CP) imagwiritsidwa ntchito popititsa madzi osavomerezeka komanso othandiza. Makina apamwamba kwambiri amapereka chitetezo chamadzi abwino ndikusintha zotsatsa ndi mphamvu za kusakaniza, kuwapangitsa kukhala abwino kwa malonda a tiles ndi matope.
2. Mlingo wapansi
Mlingo wa zolowa m'malo (DS) amatanthauza kuchuluka kwa magulu a hydroxyl pa molekyulu ya cellulose omwe alowa m'malo mwa methoxy kapena hydroxypyl magulu. Kusintha kumeneku kumathetsa kusandulika, khwala, ndi mafuta a hpmc.
Kusungunuka: Makhalidwe apamwamba a DS nthawi zambiri amawonjezera madzi osungunuka. Mwachitsanzo, HPMC yokhala ndi methoxy yapamwamba imasungunula mosavuta m'madzi ozizira, omwe amakhala opindulitsa pakuyimitsidwa kwa mankhwala ndi ma syrus pomwe kusungunuka mwachangu ndikofunikira.
Miyendo yamafuta: DS imakhudzanso kutentha kwa kutentha. HPMC yokhala ndi gawo lalikulu la zolowa m'malo mwa kutentha pang'ono, zomwe ndizopindulitsa pakugwiritsa ntchito chakudya komwe ingagwiritsidwe ntchito kupanga ma gels okhazikika. Mosiyana ndi izi, otsika DS HPMC amagwiritsidwa ntchito pakugwiritsa ntchito pofuna kukhazikika kwa matenthedwe.
3. kukula kwa tinthu
Kugawa kwa tinthu kwa tinthu kumakhudza kugunda kwa chilengedwe komanso thupi lazinthu zomaliza.
Mankhwala ogulitsa: kukula kwa tinthu tating'onoting'ono kwa HPMC kumasungunuka mwachangu, kumapangitsa kuti ikhale yoyenera kuti ituluke mwachangu. Kukula kwa tinthu tokulirapo kumagwiritsidwa ntchito m'mapiritsi oletsedwa, pomwe pang'onopang'ono chilengedwe chimafunidwa kuti aletse mankhwala osokoneza bongo.
Ntchito Yomanga: Ntchito zomangamanga, tinthu tating'onoting'ono ta hpmc zimathandizira kusuntha komanso kukhazikika kwa kusakaniza. Izi ndizofunikira pakuwonetsetsa zojambulajambula mu utoto, zokutira, ndi zomatira.
4. Madzi
Kuyera kwa HPMC, makamaka pankhani ya kukhalapo kwa oipitsidwa ndi zitsulo zolemera komanso zitsulo zolemetsa, ndizovuta, makamaka m'magulu ogulitsa ndi zakudya.
Mankhwala ndi chakudya: Magawo apamwamba kwambiri a HPMC ndikofunikira kuti akwaniritse mfundo zowongolera ndikuwonetsetsa kuti ndi chitetezo. Zosakhumudwitsa zimatha kukhudza magwiridwe antchito a polymer ndi zoopsa zaumoyo. PERMEUUTICARICE-GPMEC HPMC iyenera kutsatira malangizo okhwima monga omwe atchulidwa mu pharmacopeas (USP, EP) yaonongeka.
5. Ntchito yapadera
Mapulogalamu a mankhwala:
Mafinya ndi mafilimu: otsika pang'ono - ma virus okwera hpmc grades (5-100 cp) amakonda kwambiri mapiritsi ndi mafilimu omwe amathandizira kuti asokonezeke.
Kutulutsidwa: Kutulutsidwa Kwambiri: Kutulutsa Kwakukulu kwa HPMC HPME (1000-4000 CP) ndibwino kuti mutulutsidwe. Amapanga chotchinga chachikulu chomwe chimasinthana ndi mankhwala osokoneza bongo.
Mayankho a ophthalmic: Oyera-oyera-okwera kwambiri hpmc (pansipa 5 cp) amagwiritsidwa ntchito m'madontho amaso kuti apereke mafuta osasokoneza.
Makampani Ogulitsa Chakudya:
Otsatsa ndi okhazikika: otsika pang'ono, ma virukitala a hpmc gpmc gypm (5-1000 cp) amagwiritsidwa ntchito kufinya ndikukhazikitsa zinthu. Amakhala bwino kapangidwe ndi alumali - moyo wa sosuces, mavalidwe, ndi zinthu zophika.
Zakudya za pazakudya: HPMC yokhala ndi mafayilo apamwamba imagwiritsidwa ntchito ngati chowonjezera cha zakudya zotsika kwambiri, ndikupatsa kuchuluka kochuluka komanso kuthandizira kugaya.
Makampani omanga:
Zogulitsa za simenti: Pakati pa mafayilo apamwamba a HPMC (100-200,000 CP) amagwiritsidwa ntchito kukonza madzi osungidwa, komanso kutsatira. Izi ndizofunikira pakugwiritsa ntchito ngati mataoma, otembenukira, ndi mazira.
Utoto ndi zokutira: Maphunziro a HPMC omwe ali ndi mawonekedwe oyenera komanso kukula kwa tinthu amathandizira rheology, kukhazikitsa, komanso kukhazikika kwa utoto, zomwe zimapangitsa kuti masimali osungunuka komanso a alumali.
Magawo osiyanasiyana a HPMC amapereka katundu wosiyanasiyana womwe ungagwiritsidwe ntchito pazosowa zapadera m'mafakitale osiyanasiyana. Kusankha kwa kalasi yochokera ku mafayilo, kuchuluka kwa kulowetsa, kukula kwa tinthu, kukula kwa tinthu, kumachita zinthu moyenera pakukonzekera kugwiritsa ntchito pulogalamu yomwe mukufuna. Mwa kumvetsetsa izi, opanga amatha kusankha gawo loyenerera la HPMC kuti mukwaniritse zotsatira zabwino, ngakhale zili mu mankhwala, chakudya, kapena zomanga. Njira yolumikizira iyi imatsimikizira kufunikira, chitetezo, ndi mtundu, ndikuwunikiranso kusintha kwa HPMC mu mafakitale.
