Imwe mu nyongeramusaruro ikoreshwa muburyo bwumye-ivanze ni hydroxyethyl selulose (HEC). HEC ni selile idafite ionic ether ifite umubyimba, kubika amazi, gutuza, hamwe nuburyo bwo guhagarika. Ikoreshwa cyane mubikoresho byo kubaka, cyane cyane mumashanyarazi yumye.
1. Uruhare rwa HEC mukumisha-kuvanga
Muri minisiteri yumye, HEC igira uruhare runini mu gufata amazi, kubyimba no kunoza imikorere yubwubatsi:
Kubika amazi: HEC ifite amazi meza kandi irashobora kugabanya gutakaza amazi. Ibi ni ingenzi cyane kubutaka bwumye-buvanze kuko bwongerera igihe cya minisiteri, bigatuma abakozi bahindura minisiteri mugihe kirekire kandi bakazamura imikorere yubwubatsi. Byongeye kandi, gufata amazi birashobora kandi kugabanya ibyago byo guturika no kwemeza ko inzira yo gukomera ya minisiteri ari imwe kandi ihamye.
Kubyimba: Ingaruka yibyibushye ya HEC iha minisiteri ububobere bwiza, bigatuma minisiteri ifata neza hejuru yubutaka bwa substrate mugihe cyo kubaka, ntibyoroshye kunyerera, kandi bitezimbere uburinganire bwa porogaramu. Ibi biranga ingenzi cyane mubwubatsi buhagaritse kandi birashobora kuzamura cyane ubwubatsi bwa minisiteri.
Kunoza imikorere yubwubatsi: HEC irashobora gukora minisiteri yumye ivanze yoroshye kandi yoroshye kuyikoresha, bityo bikagabanya ingorane zo gukora. Bituma minisiteri igira uburyo bwiza bwo gukwirakwira no gufatira kuri substrate, bigatuma ubwubatsi burushaho gukiza abakozi no kunoza imikorere. Mubyongeyeho, irashobora kandi kongera ubushobozi bwo kurwanya kugabanuka, cyane cyane mubwubatsi bwimbitse.
2. Ibipimo byo guhitamo HEC
Mugihe uhisemo HEC, hagomba gusuzumwa ibintu nkuburemere bwa molekuline, urugero rwo gusimbuza no gukemuka, bizagira ingaruka kumikorere ya minisiteri:
Uburemere bwa molekuline: Ingano yuburemere bwa molekuline igira ingaruka mubushobozi bwo kubyimba n'ingaruka zo gufata amazi ya HEC. Muri rusange, HEC ifite uburemere bunini bwa molekile ifite ingaruka nziza yo kubyimba, ariko umuvuduko wo gutinda buhoro; HEC ifite uburemere buke bwa molekile ifite umuvuduko wo gushonga byihuse ningaruka mbi cyane. Kubwibyo, birakenewe guhitamo uburemere bukwiranye nubwubatsi bukenewe.
Impamyabumenyi yo gusimbuza: Urwego rwo gusimbuza HEC rugena gukemura no gukomera kwijimye. Urwego rwo hejuru rwo gusimbuza, niko gukemura neza kwa HEC, ariko ubukonje buzagabanuka; iyo urwego rwo gusimbuza ruri hasi, viscosity iba myinshi, ariko gukemura birashobora kuba bibi. Mubisanzwe, HEC ifite urwego ruciriritse rwo gusimbuza irakwiriye gukoreshwa mumashanyarazi avanze.
Gukemura: Igipimo cyo gusesa HEC kigira ingaruka mugihe cyo gutegura ubwubatsi. Kuri minisiteri yumye ivanze, nibyiza cyane guhitamo HEC yoroshye gutatanya no gushonga vuba kugirango tunonosore ubwubatsi.
3. Kwirinda mugihe ukoresha HEC
Mugihe ukoresheje HEC, ugomba kwitondera umubare wongeyeho nuburyo bukoreshwa kugirango umenye ingaruka nziza:
Kugenzura umubare winyongera: Umubare wiyongereye wa HEC mubisanzwe ugenzurwa hagati ya 0.1% -0.5% yuburemere bwa minisiteri. Kwiyongera cyane bizatera minisiteri kuba ndende kandi bigira ingaruka kumazi yo kubaka; kwiyongera bidahagije bizagabanya ingaruka zo gufata amazi. Kubwibyo, ikizamini kigomba gukorwa ukurikije ibikenewe kugirango umenye umubare wongeyeho.
Guhuza nibindi byongeweho: Muri minisiteri yumye ivanze, HEC ikoreshwa kenshi hamwe nizindi nyongeramusaruro nka redispersible latex powder, selulose ether, nibindi. Witondere guhuza HEC nibindi bikoresho kugirango urebe ko nta makimbirane kandi bigira ingaruka Ingaruka.
Imiterere yububiko: HEC ni hygroscopique, birasabwa kubibika ahantu humye kandi ukirinda izuba ryinshi. Igomba gukoreshwa vuba bishoboka nyuma yo gufungura kugirango ikumire imikorere idahwitse.
4. Ingaruka zo gusaba HEC
Mubikorwa bifatika, HEC irashobora kunoza cyane imikorere yubwubatsi bwa minisiteri ivanze kandi ikanoza ubuziranenge bwa minisiteri. Ingaruka yo kugumana no gufata amazi ya HEC ituma minisiteri ivanze yumye ifata neza kandi itajegajega, ibyo ntibitezimbere ubwubatsi gusa, ahubwo binongerera igihe cyo gufungura minisiteri, bigatuma abakozi bakora neza batuje. Byongeye kandi, HEC irashobora kugabanya ibibaho byo guturika hejuru ya minisiteri, bigatuma minisiteri ikomye iramba kandi nziza.
5. Kurengera ibidukikije nubukungu bwa HEC
HEC ikomoka kuri selile yangiza ibidukikije ikomoka ku bidukikije kandi ikangiza ibidukikije. Byongeye kandi, HEC irasa nigiciro giciriritse kandi ihendutse, bigatuma ikwirakwizwa no gukwirakwizwa henshi mubikorwa bitandukanye byubwubatsi. Imikoreshereze ya HEC irashobora kugabanya igipimo cy’amazi-sima ya minisiteri, bityo bikagabanya ikoreshwa ry’amazi, ari nako bihuye n’ibigezweho muri iki gihe cyo kurengera ibidukikije mu nganda zubaka.
Ikoreshwa rya HEC muri minisiteri yumye ivanze irashobora kunoza cyane imikorere ya minisiteri kandi ninyongera yingirakamaro mubwubatsi. Kubungabunga amazi meza, kubyimba no guhuza n'ubwubatsi bizamura imikorere yubwubatsi kandi bituma ireme rihamye. Guhitamo
uburenganzira bwa HEC no kuyikoresha neza ntibishobora kuzamura ubwubatsi gusa, ahubwo byujuje no kurengera ibidukikije nibisabwa mubukungu.
