Ngwakọta kemịkalụ: cellulose ether compound
QualiCell™ Hydroxyethyl cellulose ether (HEC) bụ klas nke na-abụghị ionic mmiri-soluble polymers. Ọdịdị ya pụtara ìhè bụ ntụ ntụ ọcha na-asọ asọ. HEC bụ ụdị hydroxylalkyl cellulose ether mepụtara site mmeghachi omume nke cellulose na ethylene oxide na alkaline ọkara. A na-achịkwa usoro mmeghachi omume ahụ nke ọma iji hụ na nkwụsi ike nke ngwaahịa sitere na batch ruo batch. A na-eji HEC dị ọcha (akọrọ akọrọ) na nlekọta onwe onye na ụlọ ọrụ ịchọ mma.
Ngwọta QualiCell™ hydroxyethyl cellulose bụ pseudoplastic ma ọ bụ mmiri na-akpachapụ anya. N'ihi ya, ngwaahịa nlekọta onwe onye nke QualiCell emebere ya na hydroxyethyl cellulose na-adị oke mgbe ewepụtara ya na akpa, mana na-agbasa ngwa ngwa na ntutu na akpụkpọ ahụ.
