Menene hypromellose aka yi daga?

Hypromellose, wanda kuma aka sani da hydroxypropyl methylcellulose (HPMC), polymer semisynthetic ne wanda aka samo daga cellulose, wanda shine polymer mai faruwa ta halitta wanda aka samu a bangon tantanin halitta. Ga yadda ake yin hypromellose:

1. Cellulose Sourcing: Tsarin yana farawa da cellulose mai narkewa, wanda za'a iya samu daga tushen shuka iri-iri kamar ɓangaren itace, zaren auduga, ko wasu tsire-tsire masu fibrous. Ana fitar da Cellulose yawanci daga waɗannan maɓuɓɓuka ta hanyar jerin hanyoyin sinadarai da injina don samun ingantaccen kayan cellulose.
2. Etherification: Tsaftataccen cellulose yana jurewa tsarin gyare-gyaren sinadarai da ake kira etherification, inda aka gabatar da ƙungiyoyin hydroxypropyl da methyl akan kashin bayan cellulose. Ana samun wannan gyare-gyare ta hanyar amsawar cellulose tare da propylene oxide (don gabatar da ƙungiyoyin hydroxypropyl) da methyl chloride (don gabatar da ƙungiyoyin methyl) a ƙarƙashin yanayin sarrafawa.
3. Tsarkakewa da Gudanarwa: Bayan etherification, samfurin da aka samu yana jurewa tsarkakewa don cire ƙazanta da samfurori daga amsawa. Ana sarrafa tsaftataccen hypromellose zuwa nau'i daban-daban kamar foda, granules, ko mafita, dangane da aikace-aikacen da aka yi niyya.
4. Gudanar da Inganci: A cikin tsarin masana'antu, ana aiwatar da matakan sarrafa inganci don tabbatar da tsabta, daidaito, da aiki na samfurin hypromellose. Wannan ya haɗa da gwaji don sigogi kamar nauyin kwayoyin halitta, danko, solubility, da sauran kaddarorin jiki da sinadarai.
5. Marufi da Rarraba: Da zarar samfurin hypromellose ya hadu da ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun bayanai, an haɗa shi cikin kwantena masu dacewa kuma ana rarraba shi zuwa masana'antu daban-daban don amfani da su a cikin magunguna, samfuran abinci, kayan kwalliya, da sauran aikace-aikace.

Gabaɗaya, ana yin hypromellose ta hanyar jerin halayen halayen sinadarai masu sarrafawa da matakan tsarkakewa da ake amfani da su ga cellulose, wanda ke haifar da yuwuwar polymer mai amfani da yawa tare da aikace-aikace iri-iri a cikin masana'antu daban-daban.
