Menene Hydroxypropyl methylcellulose?

1. Gabatarwa

Hydroxypropyl methylcellulose (HPMC) polymer ne mai narkewa da ruwa da aka yi amfani da shi sosai wanda aka samu daga cellulose.Ba ion ba ne, mara wari, mara ɗanɗano, fari zuwa fari-fari wanda ake amfani da shi sosai a cikin masana'antun abinci, magunguna, da kayan kwalliya.HPMC yana da aikace-aikace iri-iri, gami da kauri, emulsifying, dakatarwa, daidaitawa, da ƙirƙirar fim.Hakanan ana amfani dashi azaman ɗaure, mai mai, da tarwatsewa a cikin samar da allunan da capsules.

2. Raw Materials

Babban albarkatun da ake amfani da su don samar da HPMC shine cellulose, wanda shine polysaccharide wanda ya ƙunshi raka'a na glucose.Ana iya samun cellulose daga tushe daban-daban, ciki har da ɓangaren litattafan almara, auduga, da sauran filaye na shuka.Sannan ana bi da cellulose tare da tsarin sinadarai don samar da hydroxypropyl methylcellulose.

3.Tsarin Masana'antu

Tsarin masana'antu na HPMC ya ƙunshi matakai da yawa.Na farko, ana bi da cellulose tare da alkali, irin su sodium hydroxide, don samar da alkali cellulose.Wannan alkali cellulose yana amsawa da methyl chloride da propylene oxide don samar da hydroxypropyl methylcellulose.Ana wanke hydroxypropyl methylcellulose kuma a bushe ya zama farin foda.

4. Quality Control

Kula da inganci muhimmin sashi ne na tsarin masana'antu na HPMC.An ƙayyade ingancin samfurin ta hanyar tsarkin cellulose, matakin maye gurbin ƙungiyar hydroxypropyl, da matakin maye gurbin ƙungiyar methyl.Ana tabbatar da tsarkin cellulose ta hanyar gwada danko na maganin, yayin da matakin maye gurbin ya ƙayyade ta hanyar gwada matakin hydrolysis na hydroxypropyl methylcellulose.

5. Marufi

Yawanci ana tattara HPMC a cikin jaka ko ganguna.Yawancin jakunkuna ana yin su ne da polyethylene ko polypropylene, yayin da ganguna galibi ana yin su ne da ƙarfe ko filastik.Ya kamata a zaɓi kayan tattarawa don tabbatar da cewa samfurin yana da kariya daga danshi da sauran abubuwan muhalli.

6. Adana

Ya kamata a adana HPMC a wuri mai sanyi, bushe, nesa da hasken rana kai tsaye da sauran hanyoyin zafi.Hakanan ya kamata a kiyaye samfurin daga danshi da sauran abubuwan muhalli.

7. Kammalawa

HPMC shine polymer mai narkewa da ruwa wanda aka yadu da aka samu daga cellulose.Ana amfani da shi a cikin masana'antu iri-iri, ciki har da abinci, magunguna, da masana'antun kwaskwarima.Tsarin masana'antu na HPMC ya ƙunshi matakai da yawa, ciki har da jiyya na cellulose tare da alkali, halayen alkali cellulose tare da methyl chloride da propylene oxide, da tsarkakewa da bushewa na hydroxypropyl methylcellulose.Kula da inganci wani muhimmin sashi ne na tsarin masana'anta, kuma yakamata a adana samfurin a wuri mai sanyi, bushewa, nesa da hasken rana kai tsaye da sauran hanyoyin zafi.
