Hydroxypropyl Methylcellulose (HPMC)

Hydroxypropyl Methyl Cellulose wanda aka fi sani da Hypromellose, HPMC, wani nau'in ether ne maras ionic cellulose ether wanda aka samo daga polymers na halitta kamar auduga mai ladabi ko ɓangaren litattafan almara ta hanyar tsarin sinadarai. Yana gabatarwa azaman farin foda mara wari, mara guba, kuma mara ɗanɗano. Wannan sinadari yana narkar da shi cikin ruwan zafi da sanyi ba tare da wahala ba, yana samar da ingantaccen bayani mai danko tare da nau'ikan kaddarorin daban-daban, yana mai da shi nema sosai don aikace-aikace daban-daban.

HPMC yana alfahari da halaye na musamman irin su kyakkyawan kauri, ɗaure, tarwatsawa, emulsifying, ƙirƙirar fim, dakatarwa, adsorbing, gelling, fage-active, riƙe ruwa, da kare kaddarorin colloid. Yaɗuwar amfani da ita a cikin masana'antu gami da gine-gine, magunguna, abinci, PVC, yumbu, da samfuran kulawa na sirri / gida.

A cikin ɓangaren gine-gine, HPMC tana aiki azaman go-zuwa kauri don turmi mai bushewa, tile adhesives, fenti na tushen ruwa, bangon bango, da jerin turmi mai ɗaukar zafi. Bugu da ƙari, yana samun aikace-aikacen azaman kayan haɓaka magunguna da kayan abinci, yana ba da gudummawa ga samar da PVC, yumbu, da kayan wanka. Har ila yau, HPMC wani sinadari ne na gama gari a cikin yadudduka, samfuran kulawa na mutum, da abubuwan kula da gida.

HPMC yana da kaddarorin yin fim, wanda ke sa ya zama mai amfani a aikace-aikacen da ake son ƙirƙirar fim mai kariya ko haɗin gwiwa.

Thermal Gelation:

HPMC yana nuna gelation na thermal, ma'ana danko yana ƙaruwa da zafin jiki. Ana amfani da wannan kadarorin sau da yawa a cikin tsarin sakin magunguna da aka sarrafa.

Ayyukan Sama:

HPMC iya samun surfactant-kamar Properties, inganta emulsification da watsawa a wasu formulations.

Kwanciyar hankali:

HPMC yana ba da gudummawa ga kwanciyar hankali na suspensions, emulsions, da sauran abubuwan da aka tsara ta hanyar hana daidaitawa ko rabuwa.

Riƙe Ruwa:

HPMC yana da ikon riƙe ruwa, yana mai da shi mahimmanci a aikace-aikace inda kiyaye danshi yana da mahimmanci, kamar kayan gini.

Adhesion:

A cikin masana'antu daban-daban, HPMC yana inganta mannewa, ko a cikin kayan gini kamar turmi ko a cikin sutura da adhesives.

Rashin Inertness:

HPMC ba ta da ƙarfi ta hanyar sinadarai, ma'ana baya amsawa tare da sauran abubuwan da aka tsara, yana tabbatar da kwanciyar hankali da dacewa tare da kewayon kayan.

Hankalin pH:

Ana iya rinjayar kaddarorin HPMC ta hanyar pH na bayani ko tsari. Gabaɗaya yana da ƙarfi akan kewayon pH mai faɗi.
