Hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) fari ne ko haske rawaya, mara wari, ba mai guba fibrous ko powdery m shirya ta etherification na alkaline cellulose da ethylene oxide (ko chlorohydrin). Nonionic soluble cellulose ethers. Saboda HEC yana da kyawawan kaddarorin thickening, dakatarwa, tarwatsawa, emulsifying, haɗin gwiwa, ƙirƙirar fim, kare danshi da samar da colloid masu kariya, an yi amfani dashi sosai a cikin binciken mai, sutura, gini, magani da abinci, yadi, yin takarda da polymers. Polymerization da sauran filayen. Hydroxyethyl cellulose ba shi da kwanciyar hankali a yanayin zafi na al'ada da matsa lamba, yana guje wa zafi, zafi, da zafin jiki mai girma, kuma yana da ingantaccen narkewar gishiri na musamman don dielectrics. Ana ba da izinin maganinta na ruwa ya ƙunshi babban adadin gishiri kuma yana da ƙarfi.
