Ubukana bwa hydroxyethyl cellulose

Hydroxyethyl cellulose (HEC) ni polymer idafite ionic, ishongesha amazi ikoreshwa cyane nk'itsinda rikomeza, ritangiza, kandi rifata ibintu mu nganda zitandukanye, harimo imiti, amavuta yo kwisiga, n'ubwubatsi. Ubukana bwayo bugira uruhare runini mu kugena imikorere yayo muri ubu buryo.

Uburemere bwa HEC buterwa n'ibintu byinshi, birimo urugero rwayo rwo gusimbuza (DS), uburemere bwa molekile, ubwinshi bwayo, na pH. Uburemere bwa molekile buvuga umubare w'amatsinda ya hydroxyethyl yongewe kuri molekile ya cellulose, mu gihe uburemere bwa molekile buvuga ingano y'iminyururu ya polymer. Uburemere bwa HEC mu gisubizo nabwo bugira ingaruka ku buremere bwayo, aho uburemere bwinshi butuma habaho uburemere bwinshi. pH y'igisubizo ishobora kandi kugira ingaruka ku buremere, aho uburemere bwinshi bwa pH butuma muri rusange habaho uburemere buke.

Uburemere bwa HEC bushobora gupimwa hakoreshejwe viscometer, ipima ubukana bw'amazi atemba. Ubwoko butandukanye bwa viscometer bushobora gukoreshwa, harimo viscometer zizunguruka na viscometer za capillary, bitewe n'ikoreshwa ryihariye n'urwego rw'uburemere bw'amazi.

Muri rusange, HEC ifite ubukana bwinshi irakundwa cyane mu ikoreshwa aho gukurura no kugabanya ubukana ari ingenzi, nko mu miti, amavuta yo kwisiga, n'ibikoresho byo kwiyitaho. Urugero, HEC ifite ubukana bwinshi ikunze gukoreshwa mu shampoo na conditioner kugira ngo inoze imiterere n'imikorere yabyo, ndetse no mu mavuta yo kwisiga kugira ngo itange ibyiyumvo byiza kandi biryoshye.

Mu nganda z'ubwubatsi, HEC ikoreshwa nk'ikintu gikomeza ubukonje no kubika amazi mu bicuruzwa bishingiye kuri sima, nka mortiers, grouts, na beto. Uburemere bwa HEC muri ubu buryo ni ingenzi kugira ngo umusaruro wa nyuma ugerweho, ukome, no kugumana neza.

Uburemere bwa HEC bushobora kandi guhindurwa binyuze mu buryo butandukanye bwa shimi n'ubusanzwe, harimo guhuza, guhirima aside, no kuvanga n'izindi polymer. Izi mpinduka zishobora guhindura imiterere ya HEC no gutuma habaho imikorere myiza mu bikorwa byihariye.

Muri make, ubukana bwa HEC ni ikintu cy'ingenzi mu kugena imikorere yayo mu bikorwa bitandukanye. Igipimo cyo gusimbuza, uburemere bwa molekile, ubwinshi bwayo, na pH byose bigira uruhare mu kugena ubukana bwayo, bishobora gupimwa hakoreshejwe viscometer. Inganda zitandukanye n'imikorere yazo bishobora gusaba urwego rutandukanye rwa bukana, kandi impinduka kuri HEC zishobora gukorwa kugira ngo yongere imikorere yayo mu bikorwa runaka.
