Viscosity ya hydroxyethyl selile

Hydroxyethyl selulose (HEC) ni polymer idahuza, ikabura amazi ikoreshwa cyane nkibyimbye, stabilisateur, hamwe na binder mubikorwa bitandukanye, harimo imiti, amavuta yo kwisiga, nubwubatsi. Ubukonje bwabwo bugira uruhare runini muguhitamo imikorere yiyi porogaramu.

Ubukonje bwa HEC bugenwa nibintu byinshi, harimo urugero rwo gusimbuza (DS), uburemere bwa molekile, kwibanda, na pH. Urwego rwo gusimbuza rwerekeza ku mubare w'amatsinda ya hydroxyethyl yongewe kuri molekile ya selile, mu gihe uburemere bwa molekile bwerekeza ku bunini bw'iminyururu ya polymer. Ubwinshi bwa HEC mubisubizo nabwo bugira ingaruka ku bwenge bwabwo, hamwe nubushuhe bwinshi bukavamo ubwiza bwinshi. PH yumuti irashobora kandi kugira ingaruka kumyemerere, hamwe nagaciro ka pH murwego rwo hejuru bivamo ububobere buke.

Ubukonje bwa HEC burashobora gupimwa hifashishijwe viscometer, ipima ubukana bwamazi atemba. Ubwoko butandukanye bwa viscometer burashobora gukoreshwa, harimo kuzenguruka viscometer hamwe na capillary viscometer, bitewe nibisabwa byihariye hamwe nubwiza bwinyungu.

Muri rusange, ubukonje bwinshi HEC ihitamo mubisabwa aho kubyimba no gutuza ari ngombwa, nko mu miti ya farumasi, kwisiga, n'ibicuruzwa byita ku muntu. Kurugero, viscosity nyinshi HEC ikoreshwa kenshi muri shampo na kondereti kugirango itezimbere imiterere nimikorere, ndetse no mumavuta yo kwisiga kugirango utange ibyiyumvo byiza, byiza.

Mu nganda zubaka, HEC ikoreshwa nkibikoresho binini kandi bigumana amazi mu bicuruzwa bishingiye kuri sima, nka minisiteri, grout, na beto. Ubukonje bwa HEC muri izi porogaramu ni ngombwa mu kugera ku cyifuzo cyifuzwa, guhuza, no guhuza ibicuruzwa byanyuma.

Ubukonje bwa HEC burashobora kandi guhindurwa hakoreshejwe uburyo butandukanye bwimiti nubumubiri, harimo guhuza, hydrolysis ya aside, no kuvanga nizindi polymers. Ihinduka rishobora guhindura imiterere ya HEC hanyuma bikavamo imikorere yongerewe imbaraga mubikorwa byihariye.

Muncamake, viscosity ya HEC nikintu cyingenzi muguhitamo imikorere yayo mubikorwa bitandukanye. Urwego rwo gusimbuza, uburemere bwa molekile, kwibanda, hamwe na pH byose bigira uruhare mukumenya ububobere bwacyo, bushobora gupimwa hakoreshejwe viscometer. Inganda zitandukanye hamwe nibisabwa birashobora gusaba urwego rutandukanye rwubwiza, kandi guhindura HEC birashobora gukorwa kugirango byongere imikorere yabyo mubikorwa byihariye.
