Akamaro nuburyo bwo guhindura hydrophobi ya hydroxyethyl selile

Hydroxyethyl Cellulose (HEC)ni amazi ashonga nonionic selulose ether, ikoreshwa cyane mubitambaro, ibikoresho byubaka, imiti, imiti ya buri munsi nizindi nzego. Nyamara, HEC ifite amazi menshi kandi ikabura hydrophobicity, ibyo bikaba bishobora gutuma imikorere idahwitse mubikorwa bimwe na bimwe. Kubwibyo, hydrophobique yahinduwe hydroxyethyl selulose (HMHEC) yaje kubaho kugirango itezimbere imiterere ya rheologiya, ubushobozi bwo kubyimba, emulisation itajegajega hamwe no kurwanya amazi.

1. Akamaro ko guhindura hydrophobi ya hydroxyethyl selile
Kunoza imiterere yibyibushye hamwe na rheologiya
Guhindura Hydrophobi birashobora kuzamura cyane ubushobozi bwo kubyimba kwa HEC, cyane cyane ku gipimo gito. Yerekana ububobere buke, bufasha kunoza thixotropy na pseudoplastique ya sisitemu. Uyu mutungo ni ingenzi cyane mubijyanye no gutwikira, amavuta yo gucukura peteroli, ibicuruzwa byita kumuntu, nibindi, kandi birashobora kuzamura ituze no gukoresha ibicuruzwa.

Kunoza umutekano wa emulsiyo
Kubera ko HEC yahinduwe ishobora gukora imiterere ihuza igisubizo cyamazi, itezimbere cyane ituze rya emulsiyo, irashobora kugabanya gutandukanya amazi-mazi, no kunoza ingaruka za emulisation. Kubwibyo, ifite agaciro gakomeye mubisabwa murwego rwo gutwika, ibicuruzwa byita kuruhu hamwe na emulisiferi y'ibiryo.

Kongera imbaraga zo kurwanya amazi no gukora firime
Gakondo ya HEC ni hydrophilique cyane kandi irashobora gushonga byoroshye mubushuhe bwinshi cyangwa amazi, bigira ingaruka kumazi yibikoresho. Binyuze mu guhindura hydrophobique, ikoreshwa ryayo mu gutwikira, gufatisha, gukora impapuro no mu zindi nzego zirashobora kongererwa imbaraga, kandi kurwanya amazi hamwe n’imiterere ya firime birashobora kunozwa.

Kunoza imiterere yo gukata
Hydrophobic-yahinduwe na HEC irashobora kugabanya ubukonje mu bihe byogosha cyane, mugihe ikomeza guhuzagurika cyane ku gipimo gito cyogosha, bityo imikorere yubwubatsi ikagabanya no gukoresha ingufu. Ifite agaciro gakomeye mu nganda nko gucukura peteroli hamwe nububiko.

2. Guhindura Hydrophobi ya hydroxyethyl selile
Guhindura hydrophobique ya HEC mubisanzwe bigerwaho mugutangiza amatsinda ya hydrophobique kugirango ihindure imbaraga zayo kandi zibyimbye binyuze mumashanyarazi cyangwa guhindura umubiri. Uburyo busanzwe bwo guhindura hydrophobique nuburyo bukurikira:

Itsinda rya Hydrophobi
Kumenyekanisha alkyl (nka hexadecyl), aryl (nka fenyl), siloxane cyangwa fluorine kuri molekile ya HEC binyuze mumiti ya chimique kugirango itezimbere hydrophobicity. Urugero:

Ukoresheje esterification cyangwa etherification reaction yo gushushanya urunigi rurerure rwa alkyl, nka hexadecyl cyangwa octyl, kugirango ukore hydrophobique ihuza imiterere.
Kumenyekanisha amatsinda ya silicone binyuze muguhindura siloxane kugirango irusheho guhangana n’amazi.
Gukoresha impinduka ya fluor kugirango utezimbere ikirere hamwe na hydrophobicity, bikwiranye no gutwikira hejuru cyangwa gukoresha ibidukikije bidasanzwe.

Gukoporora cyangwa guhuza guhuza
Mugutangiza abahuza (nka acrylates) cyangwa guhuza imiyoboro (nka epoxy resin) kugirango habeho umuyoboro uhuza, kurwanya amazi nubushobozi bwa HEC buratera imbere. Kurugero, gukoresha hydrophobique yahinduwe HEC muri polymer emulisiyo irashobora kongera ituze ningaruka zibyibushye.

Guhindura umubiri
Ukoresheje adsorption cyangwa tekinoroji yo gutwikira, molekile ya hydrophobique itwikiriwe hejuru ya HEC kugirango ikore hydrophobicity. Ubu buryo bworoheje kandi bukwiriye gukoreshwa hamwe nibisabwa cyane kugirango imiti ihindagurika, nkibiryo nubuvuzi.

Guhindura ishyirahamwe rya Hydrophobi
Mugutangiza umubare muto wamatsinda ya hydrophobique kuri molekile ya HEC, ikora igiteranyo gifatika mugisubizo cyamazi, bityo bikazamura ubushobozi bwo kubyimba. Ubu buryo bukoreshwa cyane mugutezimbere-gukora cyane kandi bikwiranye no gutwikira, imiti ya peteroli nindi mirima.

Guhindura Hydrophobi yahydroxyethyl selilenuburyo bwingenzi bwo kunoza imikorere yimikorere, ishobora kongera ubushobozi bwayo bwo kubyimba, gutuza kwa emulisile, kurwanya amazi hamwe nimiterere ya rheologiya. Uburyo busanzwe bwo guhindura burimo hydrophobic groupe grafting, copolymerisation cyangwa guhuza guhuza, guhindura umubiri no guhindura hydrophobique. Guhitamo neza uburyo bwo guhindura birashobora guhindura imikorere ya HEC ukurikije ibisabwa bitandukanye, kugirango bigire uruhare runini mubice byinshi nko gutwika imyubakire, imiti ya peteroli, ubuvuzi bwihariye, nubuvuzi.
