HPMC (Hydroxypropyl methylcelrose) Shin an yi amfani da polymer na kowa a cikin magunguna, abinci da masana'antu na kwaskwarima. Farko ne na sel wanda aka yi ta hanyar inganta sel na halitta. Ofaya daga cikin mahimman kaddarorin HPMC shine danko, wanda ya canza dangane da dalilai daban-daban kamar zafin jiki.
Dangewar ƙwayoyin cuta ne ko tsayayyen juriya na abu don gudana. Don polmc polymers, danko shine sigar sigogi wanda ke shafar kayan aikin a aikace-aikace daban-daban. Maganin HPMC ya shafi abubuwan da yawa waɗanda da yawa kamar nauyin kwayoyin, matsayin canji, da zazzabi.
Zancen yawan zafin jiki na kayan kwalliya na HPMC
Kwallan HPMC suna nuna alaƙar rashin daidaituwa tsakanin danko da zazzabi. Gabaɗaya magana, karuwa cikin zafin jiki yana haifar da raguwa cikin danko. Za'a iya bayanin wannan hali ta:
1. Zazzabi yana shafar sadarwar hydrogen
A cikin polmc polymers, shaidu na hydrolencular na isowa suna da alhakin kafa tsarin cibiyar sadarwa mai ƙarfi. Wannan tsarin cibiyar sadarwa yana taimakawa ƙara danko na kayan. Yawan zafin jiki yana haifar da haɗin hydrogen don karya, ta haka ne rage sojojin da aka yi amfani da shi kuma don haka rage danko. Tattaunawa, raguwa a cikin zafin jiki yana haifar da ƙarin haɗin hydrogen don ƙirƙirar, wanda ya haifar da karuwa cikin danko.
2. Zazzabi yana shafar motsi na kwayoyin
A mafi girma yanayin zafi, kwayoyin a cikin silin polymer na HPMC suna da mafi girman makamashi mafi girma kuma suna iya motsa fiye da yardar kaina. Wannan ya karu kwayoyin kwayoyin cuta da tsarin polymer kuma yana rage danko.
3. Zazzabi yana shafar kaddarorin da suka fi yawa
Dalilin polymer mafita shima ya dogara da yanayin sauran sauran ƙarfi. Wasu maganganu, irin su ruwa, nuna raguwa a cikin danko kamar yadda zafin jiki ya karu saboda shaidu na hydrogen. Sabanin haka, wasu sauran hanyoyin ƙara haɓaka danko a yanayin zafi, kamar glycerol.
Yana da mahimmanci a lura cewa dalla-dalla game da dangantakar zazzabi don HPMC na iya dogara da takamaiman matakin polymer da aka yi amfani da shi da kuma ƙarfin da aka yi amfani da shi. Misali, wasu stradc maki suna nuna ingantaccen dogaro da yawan zafin jiki, yayin da wasu suka fi kwanciyar hankali. Haka kuma, danko na HPMC yana ƙaruwa yayin da ake ƙaruwa yana ƙaruwa, kuma alaƙar da ke tsakanin zafin jiki da kuma haɓaka.
Mahimmancin danko a cikin aikace-aikacen HPMC
A cikin masana'antu na harhada magunguna, HPMC wani lokaci ne wanda aka saba amfani dashi a cikin tsarin bayarwa na miyagun ƙwayoyi, inda ake buƙatar daidaituwar magani da halayyar ƙwayoyin cuta. Visccici yana taka muhimmiyar rawa a darajar sakin magani yayin da yake shafar raunin magunguna ta hanyar polymer matrix. Bugu da kari, da danko na HPMC shima yana da mahimmanci a cikin tsarin zane, kamar yadda ake buƙatar danko mafi girma don tabbatar da sutura da ci gaba.
Abubuwan abinci waɗanda ke amfani da HPMC a matsayin wakili mai kyau da emulsifier suna buƙatar takamaiman dabi'un danko don tabbatar da cewa samfurin ya kasance mai tsayayye da daidaituwa da lokacin aiki. Hakanan, kayan kwalliya waɗanda ke amfani da HPMC a matsayin mai ambato, kamar shpmoos da lotions, suna buƙatar taro da danko na HPMC a bisa ga kaddarorin da ake so.
HPMC babban polymer ne wanda ke nuna alaƙar rashin daidaituwa tsakanin danko da zazzabi. Matsakaicin yanayin zafin jiki a cikin raguwa a cikin danko, da farko saboda tasirin zafin jiki akan haɗin gwiwar hydrolencular. Fahimtar da dangantakar zazzabi-kwalliya na polmc polymer na iya taimakawa tsara kayayyaki tare da daidaito da kaddarorin da ake so. Saboda haka, nazarin dankalin HPMC yana da mahimmanci don tabbatar da ingantaccen aiki a aikace daban-daban a cikin magunguna, abinci da kayan masana'antu.
