Kedu ka esi etinye hydroxyethyl cellulose na mkpuchi?

Hydroxyethyl cellulose (HEC) bụ ihe na-eme ka ihe na-eme ka ọ dịkwuo mma na rheology modifier nke a na-eji mee ihe n'ụdị mkpuchi dị iche iche, gụnyere agba, adhesives, na sealants. Mgbe ị na-agbakwunye HEC na mkpuchi, ọ dị mkpa ịgbaso usoro isi ole na ole iji hụ na a na-agbasasị ya na mmiri mmiri nke ọma. Nke a bụ usoro izugbe iji tinye HEC na mkpuchi:

1. Kwadebe HEC mgbasa ozi HEC na-enyekarị dị ka ntụ ntụ akọrọ nke a ga-achụsasị na mmiri tupu e tinye ya na mkpuchi. Iji kwadebe mgbasa ozi HEC, tinye ego achọrọ nke ntụ ntụ HEC na mmiri mgbe ọ na-akpali akpali. Ntinye uche nke HEC na-atụ aro na mgbasa na-adabere na ngwa a kapịrị ọnụ na viscosity chọrọ nke mkpuchi.
2. Gwakọta mgbasa ozi HEC na mkpuchi Ozugbo a na-ekpochapụ mgbasa nke HEC na ihe ndị ahụ HEC na-agbasasị, jiri nwayọọ nwayọọ tinye ya na mkpuchi mgbe ị na-agwakọta na-aga n'ihu. Ọ dị mkpa ịgbakwunye mgbasa ozi HEC nwayọọ nwayọọ iji gbochie nkwụsịtụ ma hụ na a na-ekesa ya nke ọma na mkpuchi. Ekwesịrị idobe ọsọ nke ịgwakọta n'ogo dị oke ala iji gbochie ọnyà ikuku.
3. Gbanwee pH nke mkpuchi HEC na-enwe mmetụta na pH ma na-arụ ọrụ kacha mma na pH nke 6-8. Ya mere, ọ dị mkpa iji dozie pH nke mkpuchi na nke a tupu ị gbakwunye mgbasa ozi HEC. Enwere ike ime nke a site n'ịgbakwunye obere ihe na-edozi pH, dị ka amonia ma ọ bụ sodium hydroxide, na mkpuchi mgbe ị na-enyocha pH.
4. Kwe ka mkpuchi ahụ zuo ike na tozuru okè Mgbe agbakwunyere mgbasa nke HEC na mkpuchi ahụ, a na-atụ aro ka ngwakọta ahụ zuo ike ma ọ dịkarịa ala 30 nkeji iji mee ka HEC zuru ezu hydrate ma mee ka mkpuchi ahụ sie ike. Ọ dị mkpa ịkwanye ngwakọta ahụ kwa oge n'oge a iji gbochie idozi ma hụ na a na-ekesa HEC nke ọma. Ekwesịrị ikwe ka mkpuchi ahụ tozuo ma ọ dịkarịa ala awa 24 tupu ejiri ya mee ihe iji hụ na HEC ejirila mkpuchi kpuchie ya kpamkpam.

N'ozuzu, ịgbakwunye HEC na mkpuchi na-agụnye ịkwado mgbasa ozi HEC, jiri nwayọọ nwayọọ na-agbakwunye ya na mkpuchi mgbe ọ na-ejikọta ya na-aga n'ihu, na-edozi pH nke mkpuchi ahụ, na ikwe ka ngwakọta ahụ zuru ike ma tozuo tupu eji ya. Ịgbaso usoro ndị a nwere ike inyere aka hụ na HEC na-agbasasị kpamkpam na mmiri mmiri, na-eme ka mkpuchi dị mma nke ọma na ihe ndị a chọrọ rheological.
