Hydroxy Ethyl Cellulose (HEC) irazwi cyane kubera gukwirakwiza amazi adasanzwe mu gusiga amarangi. Hamwe nibisabwa byinshi mubikorwa bitandukanye, HEC yagaragaye nkinyongera yingenzi mugushushanya amarangi, bitewe nimiterere yihariye ninyungu zayo.
HEC ni polymer-eruble polymer ikomoka kuri selile, polyisikaride karemano iboneka murukuta rw'utugingo ngengabuzima. Binyuze mu ruhererekane rw'imiti, selile ihindurwa kugirango itange HEC, yerekana amazi meza. Ikiranga gifite agaciro cyane muburyo bwo gusiga amarangi aho gutandukanya inyongeramusaruro ari ngombwa kugirango ugere kubikorwa byifuzwa.
Mu gusiga irangi, HEC ikora imirimo myinshi yingenzi. Imwe mu nshingano zayo yibanze ni nkibintu byiyongera. Wongeyeho HEC gushushanya amarangi, abayikora barashobora kugenzura ubwiza bwirangi, bakemeza neza nibisabwa. Ibi nibyingenzi kugirango ugere ku gukwirakwiza no kurangiza neza mugihe cyo gukora amarangi.
HEC ikora nka stabilisateur mugutegura amarangi. Ifasha gukumira gutuza kwa pigment nibindi bice bikomeye, byemeza ko abantu bose batandukana. Uku gushikama ningirakamaro mugukomeza ubusugire bwirangi no kwirinda ibibazo nko gutandukanya amabara cyangwa gutwikira.
Ikwirakwizwa ry’amazi ya HEC nayo igira uruhare mu mikorere yayo nkuguhindura imvugo. Rheologiya bivuga imyitwarire yimikorere yibintu, naho kubijyanye no gusiga irangi, bigira ingaruka nko guhanagura, kurwanya spatter, no kuringaniza. HEC irashobora guhindurwa kugirango igere kumiterere yihariye ya rheologiya, yemerera abakora amarangi guhitamo imiterere yabyo kugirango bahuze ibisabwa nibisabwa bitandukanye.
HEC itanga ibikoresho byiza byo gukora firime kugirango irangi. Iyo ushyizwe hejuru, molekile ya HEC igira uruhare mugukora firime ikomeza yubahiriza neza kandi itanga kuramba no kurinda. Ubu bushobozi bwo gukora firime bwongera imikorere yimyenda irangi, bigatuma irwanya kwambara, ikirere, nibindi bintu bidukikije.
Inyungu zo gukoresha HEC mu gusiga irangi zirenze imikorere ya tekiniki. Dufatiye ku buryo bufatika, HEC iroroshye kubyitwaramo no kuyishiramo amarangi. Kamere yacyo ikurura amazi yorohereza gutatanya no kuvanga, kugabanya igihe cyo gutunganya no gukoresha ingufu. Byongeye kandi, HEC irahujwe nubwoko butandukanye bwinyongera zikoreshwa muburyo bwo gusiga amarangi, bigatuma bihinduka kandi bigahuza nibisabwa bitandukanye.
Ibidukikije byita ku bidukikije kandi bifasha gukoresha HEC mu gusiga irangi. Nkibintu bishobora kuvugururwa kandi biodegradable biva muri selile, HEC itanga ubundi buryo burambye bwo kubyimbye hamwe na stabilisateur. Muguhitamo ibyashingiweho na HEC, abakora amarangi barashobora kugabanya ikirere cyibidukikije no guhaza ibicuruzwa byangiza ibidukikije byiyongera.
Ikwirakwizwa ry’amazi adasanzwe rya HEC rituma ryongerwaho agaciro mu gusiga amarangi. Ubushobozi bwayo bwo kubyimba, gutuza, no guhindura rheologiya yo gushushanya amarangi bigira uruhare mugutezimbere imikorere nibisabwa. Byongeye kandi, HEC itanga inyungu zifatika n’ibidukikije, bigatuma ihitamo neza kubakora amarangi bashaka kuzamura ubuziranenge no kuramba kwibicuruzwa byabo.
