HEC Hydroxyethyl Cellulose
Hydroxyethyl Cellulose (HEC) ni inkomoko ya selile idafite selile ishonga mumazi akonje kandi ashyushye.Byakoreshejwe mugutanga ibisubizo bifite intera nini yubusa.

3.Hydroxyethyl Cellulose (HEC) Porogaramu:
Mu irangi rishingiye ku mazi, rigira uruhare mu gukwirakwiza no kurinda geles, kongera imbaraga za reaction ya sisitemu ya agglomerate, kwemeza ikwirakwizwa ry’imyororokere hamwe n’ibintu, kandi bitanga ingaruka zo kubyimba, kuzamura amazi.
Mu gucukura amavuta, ikoreshwa nka stabilisateur nogukora umubyimba, amavuta yo gusiga neza, kuzuza no guhuriza hamwe kugirango utange amashanyarazi meza kandi atuje.
Mu bwubatsi, HEC irashobora gukoreshwa nkibintu byongera umubyimba hamwe noguhuza kugirango bitezimbere kandi bikore neza, byongere imbaraga za gelline kandi birinde gucika.
Mu koza no guhuza plaster, biragaragara ko bizamura imbaraga zo gufata amazi no guhuza imbaraga.
Mumikoreshereze ya buri munsi nka menyo yinyo itanga ibintu byiza byumubiri nubumara, bigatuma biba byiza mumiterere, igihe kirekire cyo kubika, bigoye byumye kandi byinjira.
Mu kwisiga, birashobora kongera ubwinshi bwibintu, bikongeramo amavuta kandi neza.
Uretse ibyo, ifite porogaramu nini muri wino, gusiga irangi imyenda & gucapa, gukora impapuro, imiti, ibiryo, ubuhinzi nibindi.
4.Hydroxyethyl Cellulose (HEC) Ukoresheje uburyo:
Uburyo bwa mbere: Shyiramo
1. Suka amazi meza mu ndobo yatanzwe na stirrer.
2. Mugitangira kubyutsa buhoro, gusasa HEC mubisubizo.
3. Kangura kugeza granules zose za HEC zitose.
4. Banza ushyire muri anti-mildew, hanyuma ongeramo inyongeramusaruro nka pigment, dispers nibindi.
5. Komeza kubyutsa kugeza HEC yose hamwe ninyongeramusaruro zashize burundu (viscosity mubisubizo bigaragara ko byiyongera), hanyuma ushire mubindi bikoresho kugirango ubyitware.
Uburyo bwa kabiri: Tegura inzoga ya Mama kugirango ikoreshwe
Banza utegure inzoga zibyibushye, hanyuma ubishyire mubicuruzwa. Inyungu yuburyo nuburyo bworoshye, inzoga zirashobora gushirwa mubicuruzwa.Uburyo nuburyo bwo gukoresha burasa na 1-4 muburyo (Ⅰ), be rwose uzunguruke kugeza ushonge neza mumuti uhamye kandi mwinshi hanyuma ushire imiti irwanya mildew mubinyobwa byababyeyi hakiri kare bishoboka.
Uburyo bwa gatatu: Tegura ibikoresho bisa na Gruel kugirango ukoreshe
Kubera ko ibishishwa kama bidashobora gukemuka kuri HEC, birashobora gukoreshwa mugutegura ibintu bisa na gruel.Ibikoreshwa cyane ni Ethylene glycol, propylene glycol hamwe nogukora firime (hexamethylene-glycol, diethyl glycol butyl acetate nibindi) Noneho rero ni urubura amazi, irashobora kandi gutegurwa hamwe numuti ukomoka mubintu kama gruel.
Ibikoresho bisa na gruel birashobora gushirwa mubicuruzwa kuko HEC mubintu bisa na gruel byashizwemo kandi bikabyimba, bigashyirwa mubicuruzwa birahita bishonga kandi bigatera umubyimba, ariko komeza ubyuke kugeza bishonge burundu.
Mubisanzwe ibikoresho bisa na gruel biboneka mukuvanga ibinyabuzima byamazi cyangwa urubura hamwe na HEC mukigereranyo cya 6: 1, nyuma yiminota 5-30 HEC hydrolyzes kandi ikabyimba cyane.Uburyo ntibukoreshwa mugihe cyizuba bitewe nubushyuhe.
5.Ubuyobozi bwo gusaba inganda zisiga amarangi
Ingaruka Zibyibushye
Hydroxyethy Cellulose itanga irangi rya latex cyane cyane irangi rya PVA hamwe nibikorwa byiza byo gutwikira.Iyo irangi ari paste yuzuye, nta flocculation izabaho.
Hydroxyethy Cellulose ifite ingaruka nyinshi zo kubyimba, bityo irashobora kugabanya igipimo, kunoza igiciro-cyiza cyo gukora, no kongera imbaraga zo gukaraba amarangi.
Ibyiza bya Rheologiya
Igisubizo cyamazi ya Hydroxyethy Cellulose ni sisitemu itari Newtonian, kandi imiterere yumuti yitwa thixotropy.
Muburyo buhagaze, nyuma yibicuruzwa bimaze guseswa burundu, sisitemu yo gutwikira irashobora gukomeza kumera neza kandi ishobora gufungura leta.
Mugihe cyo guta, sisitemu irashobora kugumana ubukonje buringaniye, gukora ibicuruzwa bifite amazi meza, kandi ntibisuke.
Mugihe cyo gukaraba no gufunga uruziga, ibicuruzwa biroroshye gukwirakwira kuri substrate, kuburyo bworoshye kubwubatsi, kandi hagati aho, bifite imbaraga zo kurwanya spatter.
Hanyuma, nyuma yo gusiga irangi rirangiye, ubwiza bwa sisitemu buzahita busubirana, kandi irangi rizahita ribyara ibintu bigabanuka.
Gutatana no gukemura
Hydroxyethy Cellulose yose ivurwa no gutinda gushonga, kandi mugihe wongeyeho ifu yumye, irashobora gukumira neza cake no kwemeza ko hydrasiyo itangira nyuma yo gukwirakwiza bihagije ifu ya HEC.
Hydroxyethy Cellulose nyuma yubuvuzi bukwiye burashobora kugenzura neza igipimo cyo gusesa hamwe nubwiyongere bwibicuruzwa.
Ububiko
Hydroxyethy Cellulose ifite imikorere myiza irwanya mildew, itanga igihe gihagije cyo kubika amarangi, kandi ikarinda neza gutuza pigment nuwuzuza.a
