Mmetụta nke Hydroxy Ethyl Cellulose na mkpuchi mkpuchi mmiri

Hydroxyethyl cellulose (HEC) bụ ihe mgbakwunye na-emekarị na mkpuchi mmiri na-adabere na ya n'ihi ikike ya imeziwanye ihe nke mkpuchi ahụ. Nke a bụ ụfọdụ mmetụta nke HEC na mkpuchi mmiri:

1. Thickening: HEC bụ polymer soluble mmiri nke nwere ike ịbawanye viscosity nke mkpuchi mmiri, na-eme ka ọ dị mfe itinye na imeziwanye ihe ndị na-asọpụta ha. Mmetụta dị ukwuu nke HEC nwekwara ike inye aka gbochie ịla azụ na ntapu.
2. Nkwụsi ike: HEC nwere ike ime ka mkpuchi nke mmiri dị jụụ site na igbochi nkewa nke ihe ndị na-emepụta ihe na ijide n'aka na ha nọgidere na-ekesa otu. Nke a na-enyere aka melite ogo zuru oke na nkwụsi ike nke mkpuchi.
3. Nhazi ihe nkiri: HEC nwere ike ịmepụta ihe nkiri siri ike ma na-agbanwe agbanwe mgbe ọ na-etinye ya na mkpuchi mmiri. Ihe nkiri a nwere ike imeziwanye ihe mkpuchi ahụ, nrapanye, na iguzogide mmiri.
4. Mgbanwe nke Rheology: HEC nwere ike gbanwee rheology nke mkpuchi mmiri na-eme ka ọ dịkwuo mma site n'ịkwalite àgwà mkparị ha. Nke a pụtara na mkpuchi ahụ ga-adị gịrịgịrị mgbe a na-etinye ya, na-eme ka ọ dịkwuo mfe ịgbasa, ma ọ ga-adịkwu njọ mgbe ọ na-adịghị etinye ya, nke ga-enyere ya aka ịrapara n'elu.
5. Njide mmiri: HEC nwere ike inye aka idobe mmiri n'ime mkpuchi mmiri, nke nwere ike igbochi ha ihicha ngwa ngwa. Nke a nwere ike ịba uru karịsịa na gburugburu ebe dị ọkụ ma ọ bụ nke kpọrọ nkụ, ebe mkpuchi nwere ike ịkpọọ ngwa ngwa wee ghọọ nkụ.

N'ozuzu, HEC nwere ike imeziwanye arụmọrụ nke mkpuchi mmiri na-eme ka ọ dịkwuo mma site n'ịkwalite nkwụsi ike, nkwụsi ike, mmepụta ihe nkiri, rheology, na njide mmiri. Ọ bụ ihe mgbakwunye dị iche iche nke a pụrụ iji mee ihe n'ụdị mkpuchi dị iche iche, gụnyere agba, primers, na varnishes.
