Kedu onye na-emepụta hydroxyethylcellulose?

Hydroxyethylcellulose (HEC) bụ polymer sịntetik nke a na-eji n'ọtụtụ ụlọ ọrụ maka ebumnuche dị iche iche. Ọ bụ ihe na-abụghị ionic, polymer soluble mmiri nke sitere na cellulose, a na-ejikwa ya dị ka ihe na-eme ka ọ dịkwuo arọ, emulsifier, stabilizer, and suspending agent.

Ụlọ ọrụ dị iche iche na-emepụta HEC, gụnyere Dow Chemical, BASF, Ashland, AkzoNobel, na Clariant. Dow Chemical bụ otu n'ime nnukwu ndị na-emepụta HEC, ma na-emepụta akara ule dị iche iche nke HEC, gụnyere ụdị Dowfax na Natrosol. BASF na-emepụta akara Cellosize nke HEC, ebe Ashland na-emepụta akara Aqualon. AkzoNobel na-emepụta ụdị Aqualon na Aquasol nke HEC, na Clariant na-emepụta akara Mowiol.

Nke ọ bụla n'ime ụlọ ọrụ ndị a na-emepụta ọkwa dị iche iche nke HEC, nke dị iche na ịdị arọ nke molecular, viscosity, na ihe ndị ọzọ. Ihe dị arọ nke HEC nwere ike ịdị site na 100,000 ruo 1,000,000, na viscosity nwere ike ịdị site na 1 ruo 10,000 cps. Akara ule HEC nke ụlọ ọrụ ọ bụla na-emepụta na-adịkwa iche n'ihe gbasara solubility, nkwụsi ike, na ndakọrịta na ihe ndị ọzọ.

Na mgbakwunye na ndị isi na-emepụta HEC, e nwekwara ọnụ ọgụgụ nke obere ụlọ ọrụ na-emepụta HEC. Ụlọ ọrụ ndị a gụnyere Lubrizol, naKima Chemical. Onye ọ bụla n'ime ụlọ ọrụ ndị a na-emepụta ọkwa dị iche iche nke HEC, nke dị iche na ihe onwunwe ha.

N'ozuzu, e nwere ụlọ ọrụ dị iche iche na-emepụta HEC, ụlọ ọrụ ọ bụla na-emepụtakwa ọkwa dị iche iche nke HEC. Akara ule nke HEC nke ụlọ ọrụ ọ bụla na-emepụta dịgasị iche iche n'ihe gbasara ịdị arọ ha, viscosity, solubility, nkwụsi ike, na ndakọrịta na ihe ndị ọzọ.
