Source: Sodium hydroxide, kuma aka sani da caustic soda, tushe ne mai ƙarfi kuma ana samunsa ta kasuwanci.
Aiki: Ana amfani da NaOH don ƙaddamar da amsawa da daidaita ƙimar pH na cakuda amsa yayin aikin haɗin gwiwa.
Haɗin kai:
Haɗin kai na HPMC ya ƙunshi matakai da yawa, kuma za a iya taƙaita tsarin amsawa kamar haka:
Alkaki:
Ana kula da cellulose tare da sodium hydroxide don samar da cellulose alkaline.
Alkali cellulose yana amsawa da propylene oxide don gabatar da ƙungiyoyin hydroxypropyl.
Methylation:
Hydroxypropylated cellulose an ƙara mayar da martani tare da methyl chloride don gabatar da methyl kungiyoyin.
Wannan mataki yana ba da polymer ƙarin kwanciyar hankali da hydrophobicity.
Neutralization da tacewa:
An karkatar da cakudawar dauki don cire wuce haddi tushe.
An yi tacewa don ware cellulose da aka gyara.
Wanka da bushewa:
Ana wanke samfurin da aka raba sannan a bushe don samun hydroxypropyl methylcellulose a cikin foda ko granular form.
Halayen solubility na HPMC:
HPMC mai narkewar ruwa ne kuma ana iya daidaita iyawar sa gwargwadon matakin maye gurbin hydroxypropyl da ƙungiyoyin methyl.
Ikon shirya fim:
HPMC tana samar da sassauƙa, fina-finai masu gaskiya waɗanda suka dace da aikace-aikace a cikin masana'antar harhada magunguna da abinci.
Dankowa:
The danko na HPMC bayani za a iya sarrafawa da kuma sau da yawa amfani da matsayin thickener da gelling wakili a daban-daban formulations.
Thermal gelation:
Wasu maki na HPMC suna nuna kaddarorin thermogelling, samar da gel lokacin zafi da dawowa zuwa bayani lokacin sanyaya.
Ayyukan saman:
Ana iya amfani da HPMC azaman surfactant, kuma aikinta yana shafar matakin maye gurbinsa.
Abubuwan da ake amfani da su na HPMC:
Ana amfani da HPMC sosai a cikin samfuran magunguna azaman masu ɗaurewa, masu tarwatsawa, da ma'aikatan sakin sarrafawa a cikin allunan da capsules.
Masana'antar gine-gine:
A fannin gine-gine, ana amfani da HPMC a matsayin mai kauri a cikin kayayyakin da ake amfani da su na siminti kamar turmi da tile adhesives.
masana'antar abinci:
Ana amfani da HPMC a masana'antar abinci azaman mai kauri, emulsifier da stabilizer a cikin kayayyaki iri-iri, gami da miya, kayan zaki da ice cream.
Kayayyakin kula da mutum:
A cikin kayan kwalliya da samfuran kulawa na mutum, ana amfani da HPMC a cikin abubuwan da aka tsara kamar su creams, lotions da shampoos saboda kauri da daidaita kaddarorin sa.
Paints da Rubutun:
Ana ƙara HPMC zuwa fenti da sutura don sarrafa danko, haɓaka kaddarorin aikace-aikacen da haɓaka abubuwan ƙirƙirar fim.
Maganin Ophthalmic:
Ana amfani da HPMC a cikin zubar da ido da hawaye na wucin gadi saboda dacewarsa da kaddarorin mucoadhesive.
a ƙarshe:
Hydroxypropylmethylcellulose (HPMC) wani abu ne mai ban mamaki polymer wanda aka haɗa daga cellulose mai sabuntawa. Kaddarorin sa na aiki da yawa da aikace-aikace masu yawa sun sanya shi babban sinadari a masana'antu daban-daban, daga magunguna zuwa gini da abinci. Ta hanyar zaɓin ɗanyen kayan aiki da hankali da sarrafa sigogin kira, ana iya samar da HPMCs tare da kaddarorin da aka keɓance don saduwa da takamaiman buƙatun aikace-aikace daban-daban. Kamar yadda fasaha da buƙatu ke ci gaba da haɓakawa, da alama HPMC za ta kasance babban jigo a cikin ƙirƙira da ci gaban samfur mai dorewa a cikin masana'antu.
