HEC don Paint

HEC takaice ne don hydroxyethyl Cellulose. Hydroxyethyl celluloseHECfari ne ko kodadde rawaya, mara ɗanɗano, mara guba, fibrous ko foda mai ƙarfi wanda aka shirya ta hanyar etherification na cellulose na alkaline da ethylene oxide (ko chloroethanol). Ita ce ether mai narkewa mara-ionic cellulose. A matsayin surfactant ba ionic ba, ban da kauri, dakatarwa, haɗin gwiwa, iyo, ƙirƙirar fim, tarwatsawa, riƙewar ruwa da kariya.

Chemical fasali:

1, HEC za a iya narkar da shi a cikin ruwan zafi ko sanyi, babban zafin jiki ko tafasa ba ya haɓaka, don haka yana da nau'i mai yawa na solubility da danko Properties, da kuma wadanda ba thermal gel;

2, wanda ba shi da ionic ba zai iya zama tare da nau'in nau'in nau'in polymers masu narkewa da ruwa, surfactants, salts, shine mafi kyawun colloidal thickener dauke da babban taro na electrolyte bayani;

3, ikon riƙe ruwa sau biyu mafi girma fiye da methyl cellulose, tare da daidaitawar kwararar ruwa mai kyau,

4. HEC yana da mafi munin watsawa ikon idan aka kwatanta da gane methyl cellulose da hydroxypropyl methyl cellulose, amma mafi karfi colloid kariya ikon.

Saboda haka, hydroxyethyl cellulose ne yadu amfani da man fetur amfani, shafi, gini, magani da abinci, yadi, takarda yin da polymer polymerization dauki da sauran filayen.
