Selirulose ya Hydroxyethyl (HEC)ni eteri ya selulosi idafite ionic ishobora gushonga mu mazi, ikoreshwa cyane mu gusiga, ibikoresho by'ubwubatsi, ubuvuzi, imiti ya buri munsi n'ibindi bikorwa. Ariko, HEC ifite ubushobozi bwinshi bwo gushonga mu mazi no kudashonga mu mazi, ibyo bikaba bishobora gutuma habaho imbogamizi mu mikorere imwe n'imwe. Kubwibyo, selulosi ya hydroxyethyl cellulose (HMHEC) yahinduwe mu mazi (hydrophobically modified hydrophobically modified cellulose) yabayeho kugira ngo inoze imiterere yayo ya rheological, ubushobozi bwo gukuba, kudahindagurika kwa emulsification no kudahangana n'amazi.
1. Akamaro ko guhindura hydroxyethyl cellulose mu buryo bwo kurohama
Kunoza imiterere yo gukurura no kugabanya imiterere y'imitsi yo mu maraso
Guhindura imiterere y’amazi bishobora kongera cyane ubushobozi bwo gukurura HEC, cyane cyane iyo ikoze mu buryo budakomeye. Bigaragaza ubukana bwinshi, bifasha kunoza thixotropy na pseudoplasticity by’iyi sisitemu. Iyi miterere ni ingenzi cyane mu bijyanye no gusiga irangi, gucukura amavuta, ibikoresho byo kwita ku mubiri, nibindi, kandi bishobora kongera ubushobozi bwo kudahungabana no gukoresha neza ibicuruzwa.
Kunoza uburyo emulsion ihagaze neza
Kubera ko HEC yahinduwe ishobora gukora imiterere ihuza ibintu mu buryo bw'amazi, yongera cyane uburyo emulsion ihagaze neza, igagabanya gutandukana kw'amavuta n'amazi, kandi ikanoza ingaruka zo gukurura emulsification. Kubwibyo, ifite akamaro kanini mu bijyanye no gusiga emulsion, ibikoresho byo kwita ku ruhu ndetse n'ibigabanya ibiryo.
Kongera ubushobozi bwo kwirinda amazi no gukora filime
HEC isanzwe ikunda amazi menshi kandi yoroshye kuyashongesha mu kirere cyangwa mu mazi menshi, ibyo bigira ingaruka ku budahangarwa bw'amazi bw'ibikoresho. Binyuze mu guhindura budahangarwa n'amazi, ikoreshwa ryayo mu gusiga, kole, gukora impapuro n'ahandi hantu hatandukanye rishobora kongerwa, kandi ubushobozi bwayo bwo kudahangarwa n'amazi no gukora filime bushobora kunozwa.
Kunoza ubushobozi bwo kugabanya ubwinshi bw'ibiceri
HEC yahinduwe na hydrophobic ishobora kugabanya ubukana bw'amazi mu gihe cyo gukata cyane, mu gihe ikomeza kuba nziza ku gipimo gito cyo gukata, bityo ikarushaho kunoza imikorere y'ubwubatsi no kugabanya ikoreshwa ry'ingufu. Ifite akamaro kanini mu nganda nko gucukura peteroli no gusiga irangi mu bwubatsi.
2. Guhindura hydroxyethyl cellulose mu buryo bunyura mu mazi
Guhindura HEC hifashishijwe hydrophobic ubusanzwe bigerwaho binyuze mu gushyiraho amatsinda arwanya hydrophobic kugira ngo ahindure ubushobozi bwayo bwo gushonga no gukuba binyuze mu gutera imiti cyangwa guhindura imiterere yayo. Uburyo busanzwe bwo guhindura hydrophobic ni ubu bukurikira:
Guteranya amatsinda y'abantu batinya amazi
Kwerekana alkyl (nka hexadecyl), aryl (nka phenyl), siloxane cyangwa amatsinda ya fluorine kuri molekile ya HEC binyuze mu gukora kwa shimi kugira ngo yongere ubushobozi bwayo bwo kudakoresha amazi. Urugero:
Gukoresha uburyo bwo gupima cyangwa guhindura imiterere y’uturemangingo tw’urusobe rw’ibintu mu buryo bwa esterification kuri alkyl y’urusobe rurerure, nka hexadecyl cyangwa octyl, kugira ngo habeho imiterere ihuza ibidukikije n’amazi.
Gushyira hamwe amatsinda ya silikoni binyuze mu guhindura siloxane kugira ngo yongere ubushobozi bwayo bwo kwirinda amazi no kuyasiga.
Gukoresha uburyo bwo guhindura fluorination kugira ngo byongere ubushobozi bwo kurwanya ikirere no kudakoresha amazi, bigatuma ikoreshwa mu gusiga irangi rigezweho cyangwa mu buryo bwihariye ku bidukikije.
Guhindura Copolymerization cyangwa cross-link
Mu gushyiramo ibyuma bihuza (nk'ibinyabutabire) cyangwa ibikoresho bihuza (nk'ibinyabutabire bya epoxy) kugira ngo bikore urusobe rw'imiyoboro ihuza, ubushobozi bwo kwirinda amazi no gukuba bwa HEC burarushaho kwiyongera. Urugero, gukoresha HEC yahinduwe hifashishijwe hydrophobically muri polymer emulsions bishobora kongera ubushobozi bwo gutuza no gukuba kwa emulsion.
Guhindura imiterere y'umubiri
Hakoreshejwe ikoranabuhanga ryo gusiga cyangwa gusiga irangi ku buso, molekile zifata amazi zishyirwa ku buso bwa HEC kugira ngo zikoremo amazi runaka. Ubu buryo ni bworoshye kandi bukwiriye gukoreshwa ku bintu bikenewe cyane kugira ngo imiti ikomeze kuba mibi, nk'ibiribwa n'imiti.
Impinduka mu bijyanye n'ububanyi n'amazi
Mu gushyiramo amatsinda make y’amazi ku kinyabutabire cya HEC, birema associative aggregate mu gisubizo cy’amazi, bityo bikanoza ubushobozi bwo gukuba. Ubu buryo bukoreshwa cyane mu guteza imbere ibinyabutabire binini kandi bukwiriye gusiga irangi, imiti yo mu birunga bya peteroli n’ibindi birunga.
Impinduka mu bijyanye no guhohotera amaziselulose ya hydroxyethylni uburyo bw'ingenzi bwo kunoza imikorere yayo, bushobora kongera ubushobozi bwayo bwo gukuba, kudahindagurika kwa emulsification, kudahangana n'amazi ndetse n'imiterere ya rheological. Uburyo busanzwe bwo guhindura burimo gushyira mu matsinda ya hydrophobic, guhindura copolymerization cyangwa cross-linking, guhindura physique na guhindura hydrophobic association. Guhitamo neza uburyo bwo guhindura bishobora kunoza imikorere ya HEC hakurikijwe ibisabwa bitandukanye byo kuyikoresha, kugira ngo bigire uruhare runini mu nzego nyinshi nko gusiga irangi mu bwubatsi, imiti yo mu bikomoka kuri peteroli, kwita ku buzima bwite, n'ubuvuzi.
