Solubility na kimacellChpmc yana daya daga cikin mahimman kayan aikinta da na sinadarai. Ana iya narkar da narkar da ruwa don samar da mafita mai narkewa. Sallan da ke da alaƙa da nauyi da kuma matsayin ƙwayar ƙwayar cuta ta hydroxypropyl da methyl. Gabaɗaya, HPMC tare da ƙananan nauyin ƙwayoyin cuta na ruwa da sauƙi, yayin da HPMC tare da mafi girman nauyin ƙwayoyin cuta na kwayar cuta. A cikin mafifa a cikin ruwa, HPMC ba ta samar da ingantaccen tsarin bayani da kuma nuna halaye na yau da kullun polymer bayani. Bugu da kari, HPMC kuma yana da kyau ƙididdigar kwayoyin cuta (kamar giya da Ketones), wanda ya sa ya zama yalwa sosai a wasu mahalli na musamman.
2. Kayayyakin danko
Rage HPMC a cikin ruwa na iya samar da mafita mafita na vicitosies daban-daban, kuma dankalin ta ne yafi dacewa da nauyi, digiri na kayan aiki, daidaitaccen maida hankali da zazzabi na HPMC. Kamar yadda maida hankali ne na HPMC yana ƙaruwa, da danko na maganin yana ƙaruwa sosai, kuma danko na mafita da aka kafa ta HPMC na nauyi na kwayoyin halitta daban-daban. Kayayyakin kayan kwalliyar HPMC na yin amfani da shi sosai a cikin masana'antar abinci, musamman cikin ikon sakin magani, masu kauri da wakilan Geling.
A cikin bayani mai ruwa a cikin ruwa, danko na HPMC yawanci yana raguwa da ƙara yawan zafin jiki, wanda ke nuna cewa hpmc yana da zafi-m. Lokacin da yawan zafin jiki ya yi yawa, danko na maganin hpmc na iya raguwa, wanda ke buƙatar kulawa ta musamman a cikin wasu aikace-aikace.
3. Dorarancin Haske
HPMC yana da kyakkyawar kwanciyar hankali a cikin yanayin yanayin zafin jiki. Dankar da ta narke yana da alaƙa da nauyi na kwayar halitta, digiri na canzawa da yanayin muhalli. A zazzabi na al'ada, tsarin kwayar halitta na hpmc yana da kwanciyar hankali kuma ba mai sauƙin lalacewa ba. Koyaya, lokacin da yawan zafin jiki ya yi yawa, hpmc na iya yin amfani da m hydrolysis ko dhydroxylation, wanda ke shafar aikinsa.
Zafin thercc na HPMC yana sa shi don kula da kyakkyawan aiki a wasu mahimman yanayin (kamar a cikin sarrafa abinci ko kayan gini). Koyaya, lokacin da zazzabi ya wuce takamaiman matakin, tsarin HPMC na iya lalacewa, yana haifar da lalata.

HPMC ta nuna kyakkyawan tsari na magani a karkashin yanayin ph daban daban. Yawancin lokaci ana tsayayye a ƙarƙashin acidic, tsaka tsaki da yanayin ɗanɗano, amma a ƙarƙashin yanayin alkaline, tsarin ƙwayar kimacellChphpmc na iya canzawa, yana haifar da canje-canje a cikin ƙima da danko. Saboda haka, a wasu takamaiman aikace-aikace, yana da matukar muhimmanci a daidaita darajar PH don sarrafa kwanciyar hankali na HPMC.
Maganin HPMC yana da takamaiman ph. Musamman ma a wasu magunguna na ilimin harhada magunguna ko na HPMC sau da yawa ana amfani da su ne don shirya nau'ikan sakin mai sarrafawa saboda yana iya samun ragi na rugujewa a dabi'u daban-daban. Wannan dukiyar tana da mahimmanci a cikin tsarin sakin da aka saki kuma na iya sarrafa sakin kwayoyi.
5. Abubuwan injiniyoyi
HPMC, a matsayin kayan polymer, yana da wani ƙarfi na inji. An kirkiro maganinta a cikin ruwa a daban-daban maida hankali yana da wani ƙarfi na ƙasa da modulus na roba. Musamman lokacin da forming fim, hpmc na iya nuna kyawawan kaddarorin kayan aikin. Wannan yana ba shi damar samar da kyakkyawan taso da juriya yayin da aka yi amfani da shi azaman kayan fim ko alkama a cikin masana'antar gine-ginen.

HPMC tana da kayan gloling mai ƙarfi, musamman a ƙananan taro, yana iya samar da tsarin tabbataccen leling da ruwa. Halinsa na glelling yana da alaƙa da nauyi na kwayar halitta, nau'in da kuma maida hankali ga masu maye. A karkashin yanayin da suka dace, ana iya amfani da HPMC azaman Thickerner, wakilin Gelsmin ko emulsifier, wanda ya sa ya yi amfani da shi sosai a abinci, kayan kwalliya, kayan kwalliya da sauran filayen.
7. Aiki
HPMC yana da wani aiki na fuska saboda yana dauke da ƙungiyoyi masu amfani da ruwa. A karkashin wasu yanayi, KimaceChphpmc na iya rage yawan tashin hankali na ruwa kuma a yi amfani da shi azaman surfactant. A cikin magunguna da kayan kwalliya, ana amfani da HPMC sosai azaman emulsifier da watsawa, wanda zai iya inganta hadawa da ruwa da kuma inganta kwanciyar hankali na samfurin.
8. Biocompattsila
HPMC tana da kyakkyawan biocompativity kuma saboda haka ana amfani dashi sosai a filin biomededical. Ba a sauƙaƙa narkewar da sauƙin ɗauka a cikin jiki kuma sau da yawa ana amfani dashi azaman magunguna mai ɗaukar kaya ko don shirye-shiryen capsules magani. Saboda manyan halayen nauyin kwayar halittarsa, HPMC yawanci baya haifar da amsar rigakafi ko kuma wasu illa kuma sun dace da kayan masarufi ta hanyar hanyoyi daban-daban kamar baka, talauci da allura.
HpmChas excellent physical and chemical properties, including good solubility, adjustable viscosity, thermal stability, chemical stability and biocompatibility. Wadannan kaddarorin suna yin amfani da shi sosai a masana'antu da yawa kamar su, abinci, kayan kwalliya da gini. Fahimtar zurfin fahimta ta zahiri da kuma sunadarai kadadarai zasu taimaka inganta sakamakon aikace-aikacen ta a fannoni daban daban.
