Menene Hydroxyethyl Cellulose da ake amfani dashi?

Hydroxyethyl cellulose(HEC) shine ether cellulose maras ionic wanda aka yi daga kayan polymer na halitta cellulose ta hanyar jerin etherification. Yana da wani wari, maras ɗanɗano, farin foda ko granule mara guba, wanda za'a iya narkar da shi cikin ruwan sanyi don samar da ingantaccen bayani mai ma'ana, kuma ƙimar pH ba ta shafar rushewar. Yana da thickening, dauri, dispersing, emulsifying, film-forming, suspending, adsorbing, surface aiki, danshi-retaining da gishiri-resistant Properties. Ana amfani da shi sosai wajen fenti, gini, masaku, sinadarai na yau da kullun, takarda, hako mai da sauran masana'antu.
