Hydroxyethyl cellulose (HEC) ni polymer idashonga mu mazi ikomoka kuri cellulose, polymer isanzwe iboneka mu nkuta z'uturemangingo tw'ibimera. Ikoreshwa cyane mu nganda zitandukanye nko mu by'imiti, amavuta yo kwisiga, amarangi, kole, n'ibikomoka ku biribwa bitewe n'ubushobozi bwayo bwihariye nko gukurura, gushimangira, no kubika amazi. Ariko, kuganira ku gaciro ka pH ka HEC bisaba gusobanukirwa neza imiterere yayo, imiterere yayo, n'ikoreshwa ryayo.
Gusobanukirwa Hydroxyethyl Cellulose (HEC):
1. Imiterere y'ibinyabutabire:
HEC ikorwa binyuze mu gukorana kwa selulose na ethylene oxide, bigatuma amatsinda ya hydroxyethyl (-CH2CH2OH) yinjira mu mugongo wa selulose.
Igipimo cyo gusimbuza (DS) kivuga ku mubare mpuzandengo w'amatsinda ya hydroxyethyl kuri buri gice cya glucose mu muyoboro wa selulose kandi kigena imiterere ya HEC. Ingano nyinshi za DS zituma amazi ashonga neza kandi amazi akaba make.
2. Imitungo:
HEC irashongeshwa mu mazi kandi ikora ibisubizo bisobanutse neza, bituma ikoreshwa mu buryo butandukanye busaba imiterere iboneye.
Igaragaza imikorere ya pseudoplastic, bivuze ko ubushyuhe bwayo bugabanuka iyo ikoreshejwe nabi, bigatuma byoroha kuyikoresha no kuyifata neza.
Uburemere bw'ibisubizo bya HEC buterwa n'ibintu nk'ubwinshi, ubushyuhe, pH, no kuba hari umunyu cyangwa ibindi bisubizo.
3. Porogaramu:
Imiti: HEC ikoreshwa nk'umuti ukomeza ubushyuhe no gushimangira ubushyuhe mu miti ikoreshwa mu kunywa no mu gusukura nk'amavuta yo kwisiga, amavuta yo kwisiga, n'imiti ikoreshwa mu gusukura.
Ibikoresho byo kwisiga: Ni ikintu gikunze gukoreshwa mu bikoresho byo kwisiga birimo shampoo, amavuta yo kwisiga, n'amavuta yo kwisiga bitewe n'ubushobozi bwayo bwo gukurura no gukurura.
Amarangi n'Irangi: HEC yongerwa ku marangi, irangi, n'ibindi bikonjesha kugira ngo igenzure ubukana, inoze imiterere y'amazi atemba, kandi yongere ubushobozi bwo gukora firime.
Inganda z'ibiribwa: Mu bicuruzwa by'ibiribwa, HEC ikora nk'ikintu gikomeza ubushyuhe, gitera imbaraga, kandi gitera imbaraga mu bintu nk'isosi, isosi, n'ibikomoka ku mata.
Agaciro ka pH ka Hydroxyethyl Cellulose (HEC):
1. Gushingira kuri pH:
pH y'umuti urimo HEC ishobora kugira ingaruka ku myitwarire yawo n'imikorere yawo mu buryo butandukanye.
Muri rusange, HEC irahamye ku rugero rwa pH runini, akenshi iri hagati ya pH 2 na pH 12. Ariko, imiterere ya pH ikabije ishobora kugira ingaruka ku miterere yayo no ku buryo ihagaze neza.
2. Ingaruka za pH ku bucucike:
Uburemere bw'ibisubizo bya HEC bushobora guterwa na pH, cyane cyane iyo pH iri hejuru cyangwa iri hasi.
Hafi y’urutonde rwa pH rudafite aho rubogamiye (pH 5-8), ibisubizo bya HEC bikunze kugaragaza ubukana bwabyo ntarengwa.
Iyo pH iri hasi cyane cyangwa iri hejuru cyane, urutirigongo rwa cellulose rushobora kunyura muri hydrolysis, bigatuma ubukana n'ubudahangarwa bigabanuka.
3. Ivugurura rya pH:
Mu miterere aho gukosora pH ari ngombwa, akenshi hakoreshwa utubuto kugira ngo hagumane urugero rwa pH rwifuzwa.
Udukoresho dusanzwe nka citrate cyangwa fosfeti duhuza na HEC kandi tugafasha mu kugarura imiterere yayo mu rugero runaka rwa pH.
4. Ibigomba kwitabwaho mu gushyira mu bikorwa:
Abakora formulateur bagomba gusuzuma uburinganire bwa pH bwa HEC n'ibindi bintu biri muri formulateur.
Hari ubwo hashobora kuba ngombwa ko habaho ivugurura rya pH y'umuti kugira ngo HEC ikore neza.
Hydroxyethyl cellulose (HEC) ni polymer ifite ubushobozi bwinshi kandi ikoreshwa mu nganda zitandukanye. Nubwo ubuziranenge bwa pH buhamye muri rusange mu buryo bwagutse, ubuziranenge bwa pH bushobora kugira ingaruka ku mikorere no ku buziranenge bwayo. Gusobanukirwa isano ya pH na HEC na pH ni ingenzi mu gukora ibicuruzwa bifite akamaro kandi bihamye mu miti, amavuta yo kwisiga, amarangi, kole, n'ibiribwa. Mu gusuzuma uburyo pH ihuye n'uburyo ikoreshwa no gukoresha ingamba zikwiye zo kuyitunganya, HEC ishobora gukomeza kuba ikintu cy'ingenzi mu buryo butandukanye bwo kuyikoresha.
