Biyu hydroxypoyel methylcellulopyl methylcellulophyl sel sel nellulose cellulose

Hydroxypyl methylcellose (hpmc)Kuma sel pellulosethyl pellulose (hec) sune abubuwan da aka samo asali guda biyu masu mahimmanci ana amfani dasu sosai a masana'antu daban-daban saboda na musamman kaddarorin su na musamman. Duk da yake duka biyun an samo su ne daga sel, suna da tsarin sunadarai daban-daban da kuma aikace-aikace daban-daban.

1. Gabatarwa zuwa abubuwan da aka ƙaddara su:
Celullulose ne na halitta polysaccharide da aka samo a cikin bangon tantanin halitta, wanda ya kunshi ginshiƙi na layi na β (1 → 4) glykisidic shaidu. Ana samun abubuwan da ake gyarawa ta hanyar sel na gyarawa ta hanyar haɗa pellinghose don haɓaka takamaiman kaddarorin ko gabatar da sababbin ayyuka. HPMC da HEC sune irin waɗannan abubuwan da ake amfani dasu sosai a masana'antu a masana'antu masu kama daga magunguna don gini.

2. Kira:
HPMC ya hade ta mayar da sako tare da propylene opypypyl ƙungiyoyi kuma daga baya methyl chloride don gabatar da ƙungiyoyin methyl. Wannan yana haifar da musayar ƙungiyoyi na hydroxyl a cikin sarkar sel, samar da samfurin tare da ingantacciyar hanyar yin amfani da kayan aikin fim.

3. Tsarin sunadarai:
HPMC da HEC sun bambanta a cikin nau'ikan mahimman rukunoni da aka haɗe zuwa wakar cellulose. HPMC ya ƙunshi nau'ikan hydroxypyl da metyl, yayin da HEC ya ƙunshi ƙungiyoyin hydroxyl. Waɗannan musanya suna ba da halaye na musamman ga kowane abu mai mahimmanci, tasiri da halayen su a aikace-aikace daban-daban.

4. Kayan jiki:
Dukansu HPMC da HEC polymers ruwa mai narkewa tare da kyawawan kaddarorin thickening. Koyaya, suna nuna bambance-bambance a cikin danko, ƙarfin hydration, da kuma ikon samar da fim. HPMC yawanci tana da danko mai zurfi idan aka kwatanta shi da HEC a hankali, sanya ta dace da aikace-aikacen da ke buƙatar mafi girma.

Bugu da ƙari, HPMC siffofin ya bayyana kuma ga menta fina-finai saboda methyl m, yayin da HEC ya siffofin sifter da ƙarin finafinan sassauƙa. Wadannan bambance-bambance a cikin kaddarorin fina-finai suna sanya kowane kayan maye don takamaiman aikace-aikace a cikin magunguna, samfuran kulawa na mutum, da masana'antar abinci.

5. Aikace-aikace:
5.1 masana'antar harhada magunguna:
Dukansu HPMC da HEC ana amfani dasu ne a cikin tsarin magunguna kamar wuya, thickeners, da kuma masu-fim. Suna inganta amincin kwamfutar hannu, sarrafa magunguna, da haɓaka baki a cikin ruwa mai ruwa. An fi dacewa da HPMC don samun tsadar saki saboda yawan hancin sa, yayin da HEC ake amfani da HEC da aka saba amfani da shi a cikin mafita da cream ɗin opphthmic saboda haɓakar ruwa da ruwa tare da ruwayen halittarsa.

Kamfanin masana'antar 5.2:
A cikin masana'antar gine-gine,HpmCdaHecAna aiki da ƙari azaman ƙari a cikin kayan ciminti, kamar harsuna, budurrs, da kuma waɗanda suka yi. Suna haɓaka aiki, riƙewar ruwa, da kuma adhesion, sakamakon haɓaka aikin da kuma karko na samfurin ƙarshe. An fi son HPMC don mafi girman ƙarfin riƙewar ruwa, wanda ya rage yawan fatattaka da inganta lokaci.

5.3 kayayyakin kulawa na mutum:
Dukansu abubuwan da ke faruwa suna nemo aikace-aikace a samfuran kulawa na mutum kamar shamfu, lotions, da cream kamar yadda wakilai masu kauri, da kuma dillali. HEC ba da santsi da m zane-zane zuwa tsari, sanya shi dace da kayan kulawar gashi da kirim na fata. HPMC, tare da kayan aikin samar da kayan aikin fim, ana amfani dashi a cikin kayan kwalliyar rana da kayan shafawa suna buƙatar tsayayya da sutura mai dadewa.

Masana'antar masana'antu:
A cikin masana'antar abinci, HPMC kuma HEC suna bauta a matsayin wakilai masu tsayayye, da kuma rubutattun abubuwa a cikin samfuran daban-daban waɗanda suka haɗa da suttura, sutura, da kayan zaki. Suna inganta bakin, ya hana syneresis, kuma inganta halayen kayan abinci na kayan abinci. A sau da yawa ana fifita HPMC don tsabta da kwanciyar hankali, yana sa ya dace domin aikace-aikacen da ke buƙatar m gels da tsayayyen emulsions.

6. Kammalawa:
Hydroxypyl methylcelose (hpmc) da sel sel (hpmc) da sel sel met ne tare da keɓaɓɓun tsarin sunadarai, kaddarorin, da aikace-aikace. Duk da yake duka suna miƙa kyakkyawan thickening da kayan samar da fim, suna nuna bambance-bambancen a cikin danko, tsabta na fim, da halin hydration. Fahimtar wadannan bambance-bambance yana da mahimmanci don zaɓin abubuwan da suka dace don takamaiman aikace-aikacen a kan masana'antu, gini, kula, da abinci. Kamar yadda bincike ya ci gaba zuwa ci gaba, kara gyare-gyare da aikace-aikace na abubuwan da ke tattare da selulose ana tsammanin, suna ba da gudummawa ga mahimmancin sassan masana'antu da yawa.
