Menene bambanci tsakanin hydroxyethyl cellulose da ethyl cellulose

Mutane da yawa ba za su iya bambance tsakanin hydroxyethyl cellulose da ethyl cellulose ba. Hydroxyethyl cellulose da ethyl cellulose abubuwa ne daban-daban guda biyu. Suna da halaye kamar haka.

1 hydroxyethyl cellulose:
A matsayin wani abu mai kama da surfactant mara ionic, ban da kauri, dakatarwa, ɗaurewa, flotation, samar da fim, watsawa, riƙe ruwa da samar da colloids masu kariya, yana kuma da waɗannan halaye:
1. HEC yana narkewa a cikin ruwan zafi ko sanyi, kuma baya zubewa a yanayin zafi mai yawa ko tafasa, wanda hakan ke sa shi yana da halaye iri-iri na narkewa da ɗanko, da kuma gelation mara zafi;
2. Ba shi da ionic kuma yana iya rayuwa tare da nau'ikan polymers masu narkewa cikin ruwa, surfactants da gishiri, kuma kyakkyawan mai kauri ne na colloidal wanda ke ɗauke da mafita mai yawan sinadarin electrolyte;
3. Ƙarfin riƙe ruwa ya ninka na methyl cellulose sau biyu, kuma yana da ingantaccen tsarin kwarara.
4. Idan aka kwatanta da methyl cellulose da aka sani da hydroxypropyl methyl cellulose, ikon warwatsewar HEC shine mafi muni, amma colloid mai kariya yana da ƙarfi sosai.

2 ethyl cellulose
Yana da sinadarin cellulose ether wanda ba shi da ionic wanda ba ya narkewa a cikin ruwa amma yana narkewa a cikin sinadarai masu narkewa na halitta. Yana da halaye masu zuwa:

1. Ba shi da sauƙin ƙonewa.
2. Kyakkyawan kwanciyar hankali na zafi da kuma kyakkyawan yanayin zafi.
3. Babu canza launin rana.
4. Kyakkyawan sassauci.
5. Kyakkyawan halayen dielectric.
6. Yana da kyakkyawan juriya ga alkali da kuma rashin juriya ga acid.
7. Kyakkyawan aikin hana tsufa.
8. Kyakkyawan juriya ga gishiri, sanyi da kuma shan danshi.
9. Yana da daidaito ga sinadarai, yana adanawa na dogon lokaci ba tare da lalacewa ba.
10. Ya dace da resins da yawa kuma yana da kyau a yi amfani da shi tare da duk masu amfani da filastik.
11. Yana da sauƙin canza launi a ƙarƙashin yanayin alkaline mai ƙarfi da yanayin zafi.
