Hydroxyethyl cellulose (HEC) ni polymer idashonga mu mazi ikomoka kuri cellulose. Ikoreshwa cyane mu nganda zitandukanye, harimo n'ibishushanyo, aho ikora nk'ikintu gikomeza ubukana, ihindura imiterere y'umubiri, kandi igatuma ibintu bikomera. Ubushobozi bwa HEC bwo kongera ubukana bw'ibishushanyo ni ingenzi mu bikorwa byinshi, bigatuma ikoreshwa neza, ikora neza kandi iramba.
Imiterere ya Hydroxyethyl Cellulose
HEC ikorwa binyuze mu guhuza selulosi na ethylene oxide mu gihe cy’imiterere ya alkaline, bigatuma habaho polymer ifite amatsinda ya hydroxyethyl afatanye n’umugongo wa selulosi. Igipimo cyo gusimbuza (DS) n’igipimo cya molar substitution (MS) ni ibipimo by’ingenzi bigira ingaruka ku miterere ya HEC. DS yerekeza ku mubare mpuzandengo w’amatsinda ya hydroxyl kuri molekile ya selulosi yasimbuwe n’amatsinda ya hydroxyethyl, mu gihe MS yerekana umubare mpuzandengo w’amatsinda ya ethylene oxide yagiranye na molekile imwe y’ibice bya anhydroglucose muri selulosi.
HEC irangwa no gushonga kwayo mu mazi, bigatuma ikora ibisubizo bisobanutse kandi bibonerana bifite ubukana bwinshi. Ubukana bwayo buterwa n'ibintu byinshi, birimo uburemere bwa molekile, ubwinshi bwayo, ubushyuhe, na pH y'umuti. Uburemere bwa molekile ya HEC bushobora kuva ku buke kugeza ku burebure bwinshi, bigatuma habaho gukora kole zifite ibisabwa bitandukanye byo kuba ubukana.
Uburyo bwo kongera ubukana bw'imitsi
Gutanga amazi n'ibibyimba:
HEC yongera ubukana bw'ubukorikori ahanini binyuze mu bushobozi bwayo bwo kumena amazi no kubyimba mu mazi. Iyo HEC yongewe mu buryo bw'ubukorikori bw'amazi, amatsinda ya hydroxyethyl akurura molekile z'amazi, bigatuma imiyoboro ya polymeri ibyimba. Uku kubyimba byongera ubudahangarwa bw'umuti ku gutemba, bityo byongera ubukana bwawo. Ingano y'ubukorikori n'ubukana buvamo bigira ingaruka ku bwinshi bwa polymeri n'uburemere bwa HEC.
Kuziba kw'uturemangingo:
Mu gukemura ikibazo, polima za HEC zihura n’ibibazo bitewe n’imiterere yazo y’umunyururu muremure. Uku gufungana kurema urusobe rubangamira urujya n’uruza rwa molekile ziri muri kole, bityo bikongera ubukana. Uburemere bwinshi bwa molekile HEC butuma habaho gufungana gukomeye no kwiyongera. Urugero rw’ibice bishobora kugenzurwa hakoreshejwe guhindura ingano ya polima n’uburemere bwa molekile ya HEC ikoreshwa.
Guhuza Hydrogen:
HEC ishobora gukora imigozi ya hydrogen hamwe na molekile z'amazi n'ibindi bice biri muri iyo formulaire ya kole. Iyi migozi ya hydrogen igira uruhare mu gukora imigozi ihamye mu buryo burushijeho kuba bwiza. Amatsinda ya hydroxyethyl ari ku mugongo wa cellulose yongera ubushobozi bwo gukora imigozi ya hydrogen, bikongera ubukana.
Imyitwarire yo gukata imisatsi:
HEC igaragaza imyitwarire yo gukata, bivuze ko ubushyuhe bwayo bugabanuka iyo ikoze mu gukata. Iyi miterere ni ingirakamaro mu gukoresha kole kuko ituma byoroha kuyikoresha munsi yo gukata (nk'iyo gukwirakwira cyangwa koza) mu gihe igumana ubushyuhe bwinshi iyo iruhutse, bigatuma ikora neza kandi ihamye. Imyitwarire yo gukata kole ya HEC iterwa no guhuza iminyururu ya polymer mu cyerekezo cy'imbaraga zikoreshwa, bigagabanya imbaraga zo mu mutima by'agateganyo.
Ikoreshwa mu miterere y'imitako ifatana
Ibikoresho byo gufunga bishingiye ku mazi:
HEC ikoreshwa cyane mu mavuta akozwe mu mazi, nk'ayo mu mpapuro, imyenda, n'ibiti. Ubushobozi bwayo bwo gukurura no gushimangira uburyo bwo gukurura butuma ikomeza kuvanga neza kandi byoroshye kuyikoresha. Mu mavuta yo gukurura impapuro n'ayo gupfunyika, HEC itanga ubukana bukenewe kugira ngo ikoreshwe neza kandi ikomere.
Ibikoresho byo gukodesha mu bwubatsi:
Mu bukorikori bw'ubwubatsi, nk'ubukoreshwa mu gushyiraho amatafari cyangwa gupfuka inkuta, HEC yongera ubukana bw'ubukorikori, yongera ubushobozi bwo gukora no kudakomera kw'ubukorikori. Uburyo HEC ikomeza gukuba butuma kole iguma mu mwanya wayo mu gihe cyo kuyikoresha no kuyishyiraho neza, bigatuma ikomeza gukomera.
Amakorido yo kwisiga no kwita ku buzima bwite:
HEC ikoreshwa kandi mu bikoresho byo kwisiga no kwita ku buzima bw'umuntu ku giti cye bisaba imiterere yo kole, nko mu bikoresho byo gutunganya imisatsi na masks yo mu maso. Muri ubu buryo, HEC itanga uburyo bworoshye kandi bungana, yongera imikorere y'ibicuruzwa n'uburambe bw'umukoresha.
Imiti ikora ku buryo bworoshye:
Mu nganda zikora imiti, HEC ikoreshwa mu bice by’uruhu bigenzurwa n’uruhu ndetse no mu zindi nzira zo gutanga imiti aho ubushyuhe bugenzurwa ari ingenzi cyane kugira ngo kole ikore neza. HEC igenzura ko urwego rw’ikole rungana, rutanga imiti itangwa neza kandi ifatanye n’uruhu.
Ibintu bigira ingaruka ku kongera ubukana bw'imitsi
Kwibanda ku bintu:
Ubwinshi bwa HEC mu buryo bwo gufunga bungana neza n'ubwinshi bwa viscosity. Ubwinshi bwa HEC butuma viscosity yiyongera bitewe n'imikoranire ikomeye y'uruhererekane rwa polymer n'imigozi. Ariko, ubwinshi bukabije bushobora gutera ubwinshi bwa gelation no kugorwa no gutunganya.
Uburemere bwa molekile:
Uburemere bwa molekuli ya HEC ni ikintu cy'ingenzi mu kumenya ubukana bwa kole. HEC ifite uburemere bwinshi bwa molekuli itanga ubukana bwinshi ku rugero ruto ugereranije n'ubwoko buke bwa molekuli. Guhitamo uburemere bwa molekuli biterwa n'ubukana bwifuzwa n'ibisabwa mu ikoreshwa.
Ubushyuhe:
Ubushyuhe bugira ingaruka ku bushyuhe bw'ibisubizo bya HEC. Uko ubushyuhe bwiyongera, ubushyuhe bukunze kugabanuka bitewe no kugabanuka k'ubufatanye bwa hydrogen no kwiyongera kw'uburyo molekile zigenda. Gusobanukirwa isano y'ubushyuhe n'ubushyuhe ni ingenzi ku ikoreshwa ry'ibisubizo bihura n'ubushyuhe butandukanye.
pH:
pH y'uburyo bwo gufunga ishobora kugira ingaruka ku buryo HEC ikora neza. HEC irahamye ku rugero rwa pH runini, ariko imiterere ya pH ikabije ishobora gutuma habaho impinduka mu miterere ya polymer no ku buryo bwo gufunga. Gukora kole mu rugero rwa pH rwiza bituma habaho imikorere ihoraho.
Ibyiza byo gukoresha Hydroxyethyl Cellulose
Kamere itari iyonique:
Imiterere ya HEC idakoresha ioni ituma ihuzwa n'ibindi bice byinshi by'imvange, harimo n'izindi polymer, surfactants, na electrolytes. Uku guhuza kwemerera imvange ikoresha imvange ikora ku buryo butandukanye.
Kubora kw'ibinyabuzima:
HEC ikomoka kuri selulosi, umutungo kamere kandi ushobora kongera gukoreshwa. Irabora, bigatuma iba amahitamo meza ku bidukikije yo gukoresha mu gushushanya ibintu bifatanye. Ikoreshwa ryayo rijyanye n'ubwiyongere bw'ibikenewe ku bicuruzwa birambye kandi bitangiza ibidukikije.
Ituze:
HEC itanga uburyo bwo guhagarara neza ku buryo bwo gufunga, ikarinda gutandukana kw'ibice bikomeye no guhagarara kw'ibice bikomeye. Ubu buryo bwo guhagarara butuma kole ikomeza gukora neza mu gihe cyose imaze ikoreshwa ndetse no mu gihe cyo kuyikoresha.
Imiterere yo Gutunganya Filimi:
HEC ikora amafilimi yoroshye kandi abonerana iyo yumye, ibi bikaba ingirakamaro mu gukoresha kole isaba umurongo usobanutse kandi woroshye. Iyi miterere ni ingirakamaro cyane cyane mu gukoresha nk'ibirango na kaseti.
Hydroxyethyl cellulose igira uruhare runini mu kongera ubukana bw'ibirungo binyuze mu buryo nko guhumeka no kubyimba, gufungana kwa molekile, guhuza hydrogen, no kugabanya ubukana. Imiterere yayo, harimo gushonga, imiterere itari iyoni, kubora kw'ibinyabuzima, n'ubushobozi bwo gukora filime, bituma iba amahitamo meza ku bikorwa bitandukanye byo gufunga. Gusobanukirwa ibintu bigira ingaruka ku kongera ubukana bwa HEC, nko gupima, uburemere bwa molekile, ubushyuhe, na pH, bituma abakora formulaires bahindura ibicuruzwa byo gufunga kugira ngo bihuze n'ibisabwa byihariye. Mu gihe inganda zikomeje gushaka ibikoresho birambye kandi bikora neza, HEC iracyari igice cy'agaciro mu gukora ibicuruzwa byo gufunga bigezweho.
