(Hydroxypropyl) methyl cellulose | Saukewa: CAS9004-65-3

(Hydroxypropyl) methyl cellulose, wanda kuma aka sani da taƙaice ta HPMC ko lambar CAS 9004-65-3, ether ce ta cellulose da aka samu daga cellulose na halitta. Shi polymer Semi-Synthetic ne wanda ake amfani da shi sosai a masana'antu daban-daban saboda keɓaɓɓen kaddarorinsa da haɓakarsa. Ga irin wannan mahallin:

Tsarin da Kaddarorin:
1 Tsarin: An haɗa HPMC ta hanyar gyare-gyaren sinadarai na cellulose, inda aka gabatar da ƙungiyoyin methyl (-CH3) da hydroxypropyl (-CH2CHOHCH3) a kan kashin bayan cellulose.
2 Degree of Sauya (DS): Matsayin maye gurbin yana nufin matsakaicin adadin ƙungiyoyin maye a kowace naúrar glucose a cikin sarkar cellulose. Yana ƙayyade kaddarorin HPMC, kamar solubility, danko, da ikon ƙirƙirar fim.
3 Properties: HPMC yana nuna kaddarorin kamar kauri, riƙe ruwa, samuwar fim, da aikin saman. Ana iya daidaita kaddarorin ta hanyar sarrafa DS yayin haɗawa.

samarwa:
1.Cellulose Sourcing: Cellulose, farkon albarkatun kasa na HPMC, an samo shi daga tushen sabuntawa kamar ɓangaren litattafan almara ko auduga.
Etherification: Cellulose yana jurewa etherification, inda aka amsa tare da propylene oxide don gabatar da ƙungiyoyin hydroxypropyl sannan tare da methyl chloride don ƙara ƙungiyoyin methyl.
2.Purification: An tsarkake cellulose da aka gyara don cire ƙazanta da samfurori, wanda ya haifar da samfurin HPMC na ƙarshe.
Aikace-aikace:
3.Construction Industry: HPMC ana amfani dashi sosai a cikin kayan aikin gine-gine irin su ciminti na tushen turmi, plasters, da tile adhesives don inganta aikin aiki, riƙe ruwa, da mannewa.
4.Pharmaceuticals: Yana aiki a matsayin mai ɗaure, thickener, tsohon fim, da kuma stabilizer a cikin magungunan magunguna ciki har da allunan, capsules, maganin ophthalmic, da kuma creams.
5.Food Industry: HPMC abubuwa a matsayin thickener, stabilizer, da emulsifier a daban-daban abinci kayayyakin kamar miya, dressings, ice creams, da kuma gasa kaya.
6.Cosmetics da Keɓaɓɓen Kulawa: A cikin kayan kwalliya da samfuran kulawa na sirri, ana amfani da HPMC azaman mai kauri, wakili mai dakatarwa, tsohon fim, da mai daɗaɗawa a cikin creams, lotions, shampoos, da gels.
7.Paints da Coatings: Yana haɓaka danko, juriya na sag, da kayan aikin fim na fenti na ruwa, adhesives, da sutura.
