Hydroxyethyl cellulose (HEC)ni polymer idafite ionic, ishonga mu mazi iboneka binyuze mu guhindura cellulose karemano. Bitewe n'ubushobozi bwayo bwiza bwo gukuba, gushonga, guhagarika, gutuza no guhuza, HEC ikoreshwa cyane mu nganda za shimi za buri munsi, cyane cyane mu bikoresho byo gusukura amazi nk'amazi yo koza amasahani, amasabune y'intoki, na shampoo.
1. Uruhare rw'imikorere ya HEC mu bintu byo koza amasahani
Mu miterere y'amazi yo koza amasahani, imirimo y'ingenzi ya HEC irimo ibi bikurikira:
Ubunini n'amabwiriza: HEC yongera neza ubukana bw'uburyo bwo koza amasahani, bigatuma ibicuruzwa bigaragara neza, birushaho gutemba neza, kandi bikagira ubunararibonye mu gukoresha.
Guhagarara neza mu gikoresho cyo koza amasahani: Mu bintu byoza amasahani birimo ibintu by’inyongera (nk’ibice bisohora ifu n’ifu y’amapera), HEC ishobora gukumira ko ibice by’amasasu bitamera neza kandi igakomeza kuba kimwe mu bintu bifitanye isano.
Gutuza ifuro: HEC ishobora gukorana n'ibinyabutabire kugira ngo yongere ubuziranenge n'ubudahangarwa bw'ifuro.
Guhindura imiterere y'ibipimo: Nk'umuti utari uwo muri polymer, HEC ikorana cyane n'ibipimo bya anionic, cationic, na nonionic, bikarinda gutandukanya imiterere y'ibipimo.
2. Uburyo bwo Guhagarara kwa HEC
2.1. Guhagarara neza k'ubushyuhe
HEC igaragaza ubushyuhe buhamye cyane ugereranije na polimeri nyinshi karemano. Mu buryo bwa shimi bwa buri munsi kuri 25–50°C, HEC igumana imiterere ihamye ya molekile kandi ntiyoroha kwangirika.
Ndetse no mu gihe cy’ubushyuhe bwinshi (nk’igihe cyo gushonga no gushyushya) cyangwa ahantu habikwa ibintu igihe kirekire, sisitemu zifite HEC nyinshi zigumana ubushyuhe bwiza nta kugabanuka gukomeye. Iki kimenyetso ni ingenzi cyane ku igurishwa rihoraho ry’isabune mu gihe cyo gutwara ibintu mu bushyuhe bwinshi cyangwa mu masoko yo mu majyepfo.
2.2. Guhagarara kw'iyonike
Ibinyobwa byoza amasahani akenshi biba birimo imyunyu itandukanye idakomoka ku bimera (nka sodium chloride na sodium sulfate) hamwe n'ibice bya electrolyte. Izi iyoni zikunze kugabanya ingaruka z'ibinyabutabire bisanzwe. Ariko, nk'umubumbe utari uwoni, imikorere ya HEC yo gukaza umubyimba ntabwo ihinduka bitewe n'impinduka mu gipimo cya electrolyte.
Mu buryo burimo umunyu mwinshi, HEC iracyakomeza kugira ubukana buhamye n'ubuziranenge, ikarinda imvura y'umunyu no gushyira mu byiciro mu masabune mu gihe cyo kubika.
2.3. Ubudahangarwa bwa pH
pH y'amazi yoza amasahani muri rusange iri hagati ya 6.5 na 8.5. HEC igaragaza ubuziranenge buhebuje bwa shimi muri uru rwego, nta kwangirika cyangwa kudakora. Nubwo haba hari ibintu bike bya alkaline cyangwa aside mu buryo busanzwe, uruhererekane rwa molekuli za HEC rugumana amazi menshi, rugakomeza kuba imiterere imwe.
Byongeye kandi, imiterere ya HEC itari iyoni irinda kwivanga kw'imikoreshereze y'amashanyarazi guterwa n'ihindagurika rya pH, bigatuma amazi yoza amasahani agumana ubuziranenge mu gihe kirekire.
2.4. Guhuza neza
HEC igaragaza imikoranire myiza cyane n’ibintu bitandukanye bikoreshwa mu gukurura ibintu (nka AES, LAS, APG, nibindi) bidatera gukurura ibintu cyangwa gutandukanya ibintu. Imiyoboro yayo ya molekile ishobora gukora imikoranire idakomeye n’ibintu bikoreshwa mu gukurura ibintu mu gukurura ibintu, bityo bikanoza ubukana n’ubudahangarwa bw’urumuri.
Mu buryo bugoye burimo impumuro nziza, amarangi, n'ibintu bibungabunga, HEC igumana ubushobozi bwo gukwirakwira neza, ikarinda gutandukana cyangwa kugwa kw'imvura mu gihe cyo kubibika igihe kirekire.
3. Ibintu by'ingenzi bigira ingaruka ku guhagarara neza kwa HEC
3.1. Impamyabushobozi yo gusimbuza (DS) n'Impamyabushobozi yo kugabanya ubukana:
HEC zo mu rwego rwo hejuru zitanga ubushobozi bwo gushonga no kwihanganira umunyu, bigatuma zikoreshwa mu gukora isuku ibonerana; ibikoresho byo mu rwego rwo hasi bitanga ubushobozi bwo gushonga cyane ariko bifite ubushobozi bwo kudahinduka gato. Muri rusange, HEC zifite ubukana buri hagati kugeza kuri buri hejuru (25000–60000 mPa·s) zitoranywa kugira ngo zirusheho kuringaniza ubukana no gukorera mu mucyo.
3.2. Inzira yo gusesa:
HEC igomba kubanza gukwirakwizwa mu mazi akonje, hanyuma igashyushya buhoro buhoro kugira ngo ishonge neza, hirindwa gushonga. Gushonga kutuzuye bishobora gutuma ibintu bihinduka cyangwa ibintu bihinduka umuyoboro mu buryo bw'amazi, bityo bigatera ingaruka ku buryo ikorwa ry'ibinyabutabire rihoraho.
3.3. Uburyo bwo gukora Electrolyte Concentration:
Nubwo HEC yihanganira umunyu neza, ubushyuhe bushobora kugabanuka gato mu buryo bw'ubushyuhe iyo electrolyte nyinshi mu buryo bw'umubiri (>6% NaCl). Kubwibyo, mu buryo bw'umunyu mwinshi, ingano ya HEC yongewemo igomba kongerwa uko bikwiye, cyangwa hagatoranywa ubwoko bwa HEC bwahinduwe.
3.4. Ubwoko bwa Surfactant:
Uburyo HEC ikorana na sisitemu zitandukanye za surfactant buratandukanye gato. Urugero, HEC igaragaza ubushobozi bwo gufunga neza muri sisitemu za LAS na AES; mu gihe mu bintu byoza amasahani bitangiza ibidukikije birimo APG, ingaruka zo gufunga no guhagarika HEC ziragaragara cyane.
4. Ibyiza bya HEC mu byuma byoza amasahani
Umucyo wo hejuru: Umuti w'amazi ushongeshejwe uba usobanutse kandi ubonerana, ntugira ingaruka ku isura y'amazi yoza amasahani.
Kwangirika neza kw'ibinyabuzima: Bikomoka kuri selulose karemano, bijyana n'uburyo ibikomoka ku binyabutabire bya buri munsi bitangiza ibidukikije.
Kurakara gake: Ntibitera ubwivumbure bw'uruhu kandi birakwiriye mu mavuta yo koza amasahani yoroheje.
Guhuza neza: Bikoreshwa mu bwoko butandukanye bw'imiti yo koza amasahani, nk'imiti yo koza amasahani idafite aho ihuriye n'ibindi, imiterere y'imiti ivanze, n'imiti ivanze n'ifuro rinini cyangwa rito.
HECNtabwo ari ikintu cyiza cyane mu gukurura ibikoresho byo koza amasahani gusa, ahubwo ni n'ikintu cy'ingenzi gifasha mu gushimangira ubushyuhe. Uburyo bwayo bwiza bwo gushimangira ubushyuhe, gushimangira ionic, gushimangira pH, no guhuza neza bituma ibikoresho byo koza amasahani bigumana isura nziza n'imikorere myiza mu gihe cyo kubibika, kubitwara no kubikoresha. Mu guhitamo ubwoko bwa HEC no kongeramo ibintu, ubwiza rusange n'ubushobozi bwo guhangana ku isoko ry'ibikoresho byo koza amasahani bishobora kunozwa cyane. Mu gihe kizaza, hamwe no guteza imbere kurengera ibidukikije n'ubutabire burambye, HEC izagaragaza amahirwe menshi yo gukoresha ibikoresho byo koza amasahani mu buryo bugezweho.
