Hydroxypyl methylcelose (hpmc) wani abu ne na sakansoshi masu amfani da kayayyaki da yawa a cikin magunguna, abinci, kayan kwalliya da kayan gini. Rayuwar shelf ta tana nufin tsawon lokacin zai iya kiyaye jiki na jiki, sunadarai da aiki na aiki a karkashin takamaiman yanayi. Abubuwan da ke shafar rayuwar ta HPMC sun haɗa da yanayin muhalli, yanayin ajiya, kwanciyar hankali, da sauransu.
1. Yanayin muhalli
1.1 zazzabi
Zazzabi daya ne daga cikin mahimman abubuwan da suka shafi shelf rayuwa na HPMC. Babban zazzabi zai hanzarta lalata halayen HPMC, wanda ya haifar da canje-canje a cikin kayan aikinta da kuma sunadarai. Misali, HPMC na iya zama rawaya da rage danko a yanayin zafi, yana shafar ingancin sa. Sabili da haka, yanayin yanayi mai dacewa wanda aka adana HPMC ya kamata a adana shi a yanayin yanayin zafi, gabaɗaya da ke ƙasa 25 ° C, don tsawaita rayuwarsa.
1.2 zafi
Tasirin zafi akan HPMC yana da muhimmanci sosai. HPMC shine kayan polymer na ruwa wanda ya sauƙaƙe yana shan danshi. Idan zafi a cikin yanayin ajiya ya yi yawa, HPMC zai sha danshi a cikin iska, yana haifar da danko don canji, har ma da kwanciyar hankali don faruwa. Sabili da haka, ya kamata a kiyaye HPMC ta bushe lokacin da aka adana, kuma ana ba da shawarar cewa za a iya sarrafa dangin zafi a ƙasa da 30%.
2. Yanayin ajiya
2.1 cofeaging
Kayan marufi da kuma rufe ido suna da tasiri kai tsaye akan rayuwar shiryayye na HPMC. Abubuwan kayan kwalliya masu inganci zasu iya ware iska da danshi da hana HPMC daga samun rigar da ciwan. Abubuwan da aka saba amfani da kayan aikin sun hada da jakunkuna na aluminium, jakunkuna na polyethylene, da sauransu, waɗanda suke da kyawawan kayan shafe. A lokaci guda, marufi masu rufi da aka rufe na iya rage lambar HPMC tare da yanayin waje kuma mika da rayuwar sa.
2.2 Welling
Haske, musamman ma ultraviolet iradiation, na iya haifar da lalata ƙwayar cuta na HPMC kuma yana shafar ainihin kayan aikinta da keɓaɓɓen kayan. Lokacin da aka fallasa haske na dogon lokaci, HPMC na iya yin canje-canje masu launi, da sauransu saboda haka, ya kamata a adana HPMAC a cikin yanayin ɗaukar hoto.
3. Dogara mai aminci
3.1
Haskakawa na HPMC yana tasiri da darajar PH. A karkashin yanayin alkalin acidic ko alkalin hpmc zai sha hydrolysis ko lalata, yana haifar da matsaloli kamar raguwar danko da canji a cikin karuwa. Don tabbatar da kwanciyar hankali na HPMC, ana bada shawara cewa darajar pH ta warware matsalar ta ph a cikin tsaka tsaki (PH 6-8).
3.2 Rashin hankali
Kasancewar rashin karfin gwiwa yana shafar kwanciyar hankali na HPMC. Misali, ƙazanta irin su karfe na ƙarfe na iya ɗaukar lalata da lalata da hpmc, gajarta rayuwa. Sabili da haka, yakamata a sarrafa abun dajin da aka sarrafa yayin aiwatar da kayan samarwa da kayan albarkatun kasa don tabbatar da tsarkakakken HPMC.
4. Samfurin samfurin
Samfurin samfurin HPMC shima yana shafar rayuwarsa. HPMC yawanci yana wanzu a cikin foda ko granules. Tasirin abubuwa daban-daban akan rayuwarsa, kamar haka:
4.1 foda
HPMC fom foda yana da takamaiman yankin yanki kuma yana da sauƙin hygroscopic da gurbata, saboda haka, shelf da yakeyi rayuwa yana gajeru. Don matse da rayuwar shiryayye na hpmc, ya kamata a karfafa kyaffiyar marufi don kauce wa hulɗa da iska da danshi.
4.2 carphology
Abubuwan da HPMC suna da ƙaramin yanki na samaniya, suna da ƙarancin hygroscopic, kuma suna da tsawon rai. Koyaya, tranulated HPMC na iya samar da ƙura yayin ajiya da sufuri, wanda ya haifar da yanayin adrefled. Sabili da haka, spmc na mulkan shima yana buƙatar kyakkyawan copping da yanayin ajiya.
5. Yi amfani da ƙari
Don inganta kwanciyar hankali kuma ƙara rayuwar shiryayye na HPMC, ana iya ƙara masu ƙwarewa ko abubuwan da aka adana a lokacin aiwatar samarwa. Misali, ƙara maganin antiidants na iya hana lalata lalata na HPMC, kuma ƙara wakilai danshi-eriging na iya rage hygrostcopicity na HPMC. Koyaya, zabin da kuma kayan da ƙari na buƙatar da tabbataccen tabbatar da cewa ba sa shafar abubuwan aiki da amincin HPMC.
Abubuwan shiryayye na HPMC sun shafi abubuwa da yawa da yawa, gami da yanayin muhalli (ƙimar ajiya), foda, foda, granules) da amfani da ƙari. Don tsawaita rayuwar shiryayye na HPMC, waɗannan abubuwan ya kamata a yi la'akari dasu kuma yakamata a ɗauki matakan da suka dace don sarrafawa. Misali, kula da karancin zazzabi da bushewar wurin ajiya mai laushi, sarrafa abun ciki da kuma mai hankali, ana iya tabbatar da ingancin shiryayye a fannoni daban-daban.
