Menene bambanci tsakanin hydroxyethyl cellulose da ethyl cellulose

Mutane da yawa ba za su iya bambanta 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 surfactant ba ionic ba, ban da kauri, dakatarwa, ɗaure, iyo, yin fim, tarwatsawa, riƙe ruwa da samar da colloid masu kariya, shima yana da kaddarorin masu zuwa:
1. HEC yana narkewa a cikin ruwan zafi ko ruwan sanyi, kuma baya tasowa a babban zafin jiki ko tafasa, yana sa shi yana da nau'i mai yawa na solubility da danko, da kuma ba-zazzabi gelation;
2. Ba shi da ionic kuma yana iya zama tare da wasu nau'o'in nau'in polymers masu narkewa da ruwa, surfactants da salts, kuma yana da kyau mai girma colloidal thickener dauke da high-maida hankali electrolyte mafita;
3. Ƙarfin ajiyar ruwa ya ninka sau biyu fiye da na methyl cellulose, kuma yana da mafi kyawun tsari.
4. Idan aka kwatanta da methyl cellulose da aka sani da hydroxypropyl methyl cellulose, da dispersing ikon HEC ne mafi muni, amma m colloid yana da karfi da iko.

2 ethyl cellulose
Ita ce ether cellulose maras ionic wacce ba ta iya narkewa a cikin ruwa amma mai narkewa a cikin kaushi na halitta.Yana da halaye kamar haka:

1. Ba sauƙin ƙonewa ba.
2. Kyakkyawan kwanciyar hankali na thermal da kyakkyawan thermoplasticity.
3. Babu canza launin zuwa hasken rana.
4. Kyakkyawan sassauci.
5. Good dielectric Properties.
6. Yana da kyakkyawan juriya na alkali da raunin acid mai rauni.
7. Kyakkyawan aikin rigakafin tsufa.
8. Kyakkyawan juriya ga gishiri, sanyi da shayar da danshi.
9. Barga ga sinadarai, ajiya na dogon lokaci ba tare da lalacewa ba.
10. Mai jituwa tare da resins da yawa da kuma dacewa mai kyau tare da duk masu filastik.
11. Yana da sauƙi don canza launi a ƙarƙashin yanayi mai ƙarfi na alkaline da yanayin zafi.
