Hydroxy Ethyl Cellulose (HEC) - mmanụ aṅụ

Hydroxyethyl cellulose (HEC) bụ polymer soluble mmiri nke sitere na cellulose, nke a na-ejikarị eme ihe dị ka ihe ngbanwe nke rheology na onye na-ahụ maka nkwụsị nke mmiri na-arụ ọrụ n'ịgba mmanụ.

N'oge a na-egwupụta mmanụ, a na-eji mmiri na-egwupụta ihe na-eme ka mmiri na-agbapụta mmanụ, na-ebufe mkpọ ahụ n'elu, na-achịkwa nrụgide dị na olulu mmiri ahụ. Mmiri mmiri ndị a na-egwupụta ihe na-enyekwa aka mee ka olulu mmiri guzosie ike ma gbochie mmebi nguzobe.

A na-agbakwunye HEC na mmiri mmiri na-egwupụta ihe iji mee ka viscosity dịkwuo elu ma na-achịkwa ihe ndị na-asọpụta nke mmiri. Ọ nwere ike inye aka kwụsịtụ mbelata mgbịrịgba ahụ ma gbochie idozi ya, ebe ọ na-enyekwa njikwa mfu mmiri dị mma iji nọgide na-eguzosi ike n'ezi ihe nke olulu mmiri. A pụkwara iji HEC mee ihe dị ka mmanụ mmanu na ihe nzacha achicha, iji melite arụmọrụ na ịdị irè nke usoro ịkụ ala.

Otu n'ime uru HEC na-egwupụta mmanụ bụ nkwụsi ike ya na oke okpomọkụ na ọnọdụ nrụgide dị elu. HEC nwere ike ịnọgide na-arụ ọrụ rheological ya na njikwa nkwụsị nke mmiri na-ekpo ọkụ n'ọtụtụ okpomọkụ na nrụgide, na-eme ka ọ dị mma maka iji mee ihe na gburugburu ebe igwu mmiri.

HEC dakọtara na ihe ndị ọzọ a na-eji na-egwupụta mmiri mmiri, dị ka ụrọ, polymers, na salts, na enwere ike itinye ya ngwa ngwa n'ime nhazi ahụ. Obere toxicity ya na biodegradability na-eme ka ọ bụrụ enyi na gburugburu ebe obibi yana nchekwa maka iji rụọ ọrụ mgbapu mmanụ.

N'ozuzu, HEC bụ polymer na-agbanwe agbanwe nke nwere ike inye njikwa rheological dị irè na nchịkwa mmiri na-efu na mmiri mmiri na-egwupụta mmanụ. Ngwongwo ya pụrụ iche na ndakọrịta na ihe ndị ọzọ na-eme ka ọ bụrụ nhọrọ na-ewu ewu maka ịrụ ọrụ ịkụ ala n'ọtụtụ gburugburu.
