Hydroxyethyl cellulose (HEC)ni eteri ya cellulose idafite ionic, ishongesha amazi ikoreshwa cyane mu bwubatsi, mu gusiga irangi, mu binyabutabire bya buri munsi, no mu gucukura amavuta. Nubwo imirimo y'ingenzi ya HEC ikunze gufatwa nk'iy'ububyimbirwe, kubika amazi, guhindura rheology, no gukomeza guhagarara, inagaragaza imiterere imwe n'imwe yo gukora filime mu bikorwa bimwe na bimwe, cyane cyane mu gusiga irangi, kole, no gutunganya ubuso.
1. Uburyo bwo gukora filime ya HEC
Imiyoboro ya HEC irimo amatsinda menshi ya hydroxyl akunda amazi n'amatsinda ya hydroxyethyl asimbuwe igice, bituma ishonga neza mu mazi, igakora imiti ibonerana cyangwa ibonerana ya colloidal. Mu gihe cyo kumisha umuti, amazi agenda ashira buhoro buhoro, bigatuma imiyoboro ya molecule ihurirana, igakora urusobe rw'ibice bitatu ruhoraho. Uru rusobe si firime isanzwe ya thermoplastic polymer, ahubwo ni firime ifatika ikorwa ahanini binyuze mu guhuza hydrogen na intermolecular entanglement. Ugereranyije n'ibikoresho bikora firime nka polyvinyl alcohol (PVA) na poda ya polymer ishobora gushwanyagurika (RDP), ubushobozi bwa HEC bwo gukora firime ni buke, bugaragarira cyane cyane muri ibi bikurikira:
Kutagira ubucucike bwa firime: Imbaraga nke za molekile zitera ubwinshi bw'imyenge.
Kugorama cyane: Kutagira ubworoherane nyuma yo kuma no gucikagurika.
Gushonga cyane mu mazi: Nyuma yo kurema, agahu gakomeza gushonga cyangwa gushonga mu mazi, ariko ntigashobora kwihanganira amazi igihe kirekire.
Bityo, imikorere ya HEC yo gukora filime ni inyungu y'inyongera kuruta imikorere yayo y'ibanze.
2. Ibintu bigira ingaruka ku mikorere ya filime
Ingano yo Gusimbuza (DS na MS): Ingano n'ubumwe bw'impinduka za hydroxyethyl muri HEC bigira ingaruka ku guhuza no guhuza hagati y'iminyururu ya molekile. Impinduka nyinshi zikunda kongera ubushobozi bwo gushonga kw'amazi ariko zikagabanya imbaraga za firime.
Gushyiramo umuti mu buryo buhagije: Gushyiramo umuti mu buryo buhanitse bituma habaho uduce duto cyane, mu gihe uduce duto dutuma uduce duto tudakora neza nyuma yo kuma.
Imiterere yo Kuma: Kuma buhoro buhoro bituma habaho guhuza neza kw'uruhererekane rw'ibintu bito kandi bigatuma habaho firime ihoraho; guhumeka vuba bishobora gutuma ibintu bicika. Ingaruka z'inyongera: Iyo ikoreshejwe hamwe na PVA, emulsions za acrylic, cyangwa ifu ya polymer ishobora gushonga, imiterere ya HEC yo gukora firime ishobora kunozwa cyane, ikagaragaza gukomera no kudapfa amazi.
Ubushuhe bwo mu kirere: Kubera ko HEC ishobora kwangirika ku bushuhe, imiterere yayo yo gukora firime irahinduka bitewe n'ubushuhe bw'ikirere. Ubushuhe bwinshi butuma firime ifata amazi ikanakoroha.
3. Ibiranga imikorere ya Filime za HEC
Umucyo Mwiza: Bitewe n'uko molekile zikwirakwira kimwe, firime ivamo muri rusange iba ibonerana cyangwa ibonerana.
Uburyohe n'ubworoherane: Ubuso bwa firime buraryoshye cyane, bigatuma irangi rirushaho kuryoha.
Ubudahangarwa bw'amazi make: HEC isubiramo amazi mu buryo bworoshye kandi ntishobora gukoreshwa yonyine nk'agapira ko kurinda igihe kirekire.
Imiterere y'ubuhanga buke: Ububasha buke bwo gukurura no koroha bisaba kuvanga n'izindi polymer.
Kuba ibinyabutabire bihuye n'umutekano: Iyi firime ntabwo ihumanya kandi ntitera umujinya, bigatuma ikoreshwa mu bikoresho bya buri munsi by'imiti n'ibindi bikoresho by'imiti.
4. Ingaruka zo Gutunganya Filimi mu Mikoreshereze Ifatika
Amarangi n'amabara: Mu marangi ya latex, HEC ikora cyane cyane nk'ikintu gikomeza ubushyuhe n'imikorere y'amaraso. Ariko, mu gihe cyo gukora filime, ishobora no gukora firime irinda ku buso bw'irangi, igafasha gukwirakwiza amarangi n'amabara ku buryo bungana no kunoza ubwiza bw'irangi.
Ibikoresho byo kubaka: Mu bikoresho nka putty na mortier, HEC ikora agahu gato ku buso bw'uduce tw'ibumba nyuma yo kuma, bigatuma ifu ifatana neza kandi igakora neza.
Kole: Filimi ikorwa no kumisha HEC itanga uburyo runaka bwo gufatana kandi ikunze gukoreshwa hamwe na PVA cyangwa latexes mu mpapuro zo gufatana, impapuro zo gupfunyikaho, n'ibikoresho byo gupfunyikamo.
Imiti yo mu rugo n'imiti: Mu mavuta yo kwisiga no mu miti, HEC films zitanga uburyo bwiza bwo gufatana n'uruhu no kurusiga neza, mu gihe zikongera igihe cyo kubika ibintu bikora.
Gutunganya ubuso: Mu gukora impapuro n'imyenda, filime za HEC zishobora kunoza uburyo ubuso bugenda neza kandi bugacapa neza.
HECImiterere yo gukora filime ikomoka ku guhuza hydrogen no kwivanga hagati y’iminyururu ya molekile. Filimi zivuyemo zirabonerana, ziraryoshye, kandi ntizigira uburozi, ariko zifite ubushobozi buke bwo kwirinda amazi n’imbaraga za mekanike. Kubwibyo, mu bikorwa bifatika, ikunze kugaragara nk'igikoresho cy'inyongera cyo gukora filime cyangwa guhindura rheology aho kuba ibikoresho by'ibanze byo gukora filime. Mu kuvanga cyangwa guhuzwa n'izindi polymer, imiterere ya HEC yo gukora filime ishobora kunozwa cyane, bityo ikagira uruhare runini mu bijyanye no gusiga, kole, imiti ya buri munsi, n'ibikoresho by'ubwubatsi.
