Yana fayyace abubuwa share mafita tare da halayyar da ke haifar da yanayin, yana nuna kaddarorin da ke bakin ciki.
MHEC yana ba da kyakkyawan lokacin farin ciki da kuma daidaita tasirin abubuwa a cikin tsarin ruwa.
Kamar HPMC, danko na mhec mafita za a iya sarrafawa ta hanyar gyaran yanayin canzawa da nauyin kwayoyin.
4. Aikace-aikace:
Aikace-aikacen HPMC:
Masana'antar gine-gine: Ana amfani da HPMC sosai a cikin gida-da yawa, gyada-gunguma, da kuma adile adheres don inganta aiki, riƙe ruwa, da kuma m.
Magana: An yi amfani da HPMC a cikin mayafin kwamfutar, tsarin saki, ophthalmic mafita, da shirye-shirye na samarwa saboda kayan aikin mucoad.
Abinci da kayan kwalliya: HPMC suna aiki a matsayin wakili mai tsira, maimaitawa a cikin samfuran abinci, kayan kulawa na sirri, da kayan kwalliya.
Aikace-aikacen MHE:
Masana'antar Gina: MHEC da ake saba da shi a cikin sinadarai irin su kamar adile ne na tala, da kuma suka yi hakan, da kuma ficewa don riƙewar ruwa, aiki, da kuma m.
Paints da Cookings: Ana amfani da MHEC azaman RHECROOKY MENUSHANCIN A CIKIN RUWAN RUWAN ruwa, mayaka, da kuma inks don sarrafa danko, da inganta abubuwan aikace-aikace.
Maganin magunguna: MHEC ta gano aikace-aikace a cikin dakatarwar ta'addanci, shirye-shiryen ophthalmic, da kuma siffofin sakin mai sarrafawa a matsayin m da kuma karfafa wakili.
5. Fa'idodi:
Abbuwan amfãni na HPMC:
HPMC yana ba da manyan kayan fim, wanda ya dace da kayan kwalliyar kwamfutar hannu da kuma tsarin saki.
Ya nuna kyakkyawan m da halaye na ɗauri, haɓaka haɗin gwiwar daban-daban.
HPMC yana samar da yawan amfani da daidaitaccen danko da gyaran masana'antu.
Abvantbuwan amfãni na Mhec:
MHEC ya nuna banda na musamman da kuma karfafa tasiri a cikin tsarin ruwa mai ruwa, yana sa ya dace da fenti, gini, da kuma tsarin aikin magada.
Yana ba da kyakkyawan tsarin rasta ruwa, inganta aiki da adsa a cikin samfuran kayayyaki.
MHEC yana ba da halaye na rikice-rikice, yana ba da izinin sauƙin aikace-aikace da haɓaka halayen kwarara a coftings.
Yayin da duka biyu HPMC da MHEC ne Celullulose suke da irin wannan aikace-aikacen, suna nuna bambance-bambancen a cikin abubuwan da aka yisti na sunadarai, tsarin, kaddarorin, da fa'idodi. HPMC sanannu ne ga shi da kyau da kyau da kuma adhelion kaddarorin, yayin da Mhec ficikel a cikin thickening, da kuma sakamakon riƙewar ruwa. Fahimtar wadannan abubuwan da suka dace na da mahimmanci don zaɓar mafi dacewa Eldelulose mafi dacewa don takamaiman aikace-aikace a cikin masana'antu daban-daban.
