Hydroxyethyl selulose (HEC) ni ibintu byinshi kandi bikoreshwa cyane mubyimba mu gusiga amarangi. Ikora imirimo myinshi, izamura imikorere, ituze, hamwe nibikorwa bya bicuruzwa. Hano hepfo nubuyobozi bwuzuye muburyo bwo gukoresha neza hydroxyethyl selulose mumarangi no gutwikira, bikubiyemo inyungu zayo, uburyo bwo kuyikoresha, hamwe nibitekerezo.
Inyungu za Hydroxyethyl Cellulose mu marangi no gutwikira
Guhindura Rheologiya: HEC itanga imigendekere yifuzwa kandi iringaniza irangi hamwe nigitambaro, ibafasha gukwirakwira no kugabanya kugabanuka.
Kongera imbaraga: Ihindura emulioni kandi ikarinda gutandukana kwicyiciro, ikemeza gukwirakwiza pigment hamwe nuwuzuza.
Kunoza ibyifuzo bya porogaramu: Muguhindura ibishishwa, HEC yorohereza irangi kuyikoresha, haba kuri brush, roller, cyangwa spray.
Kubika Amazi: HEC ifite uburyo bwiza bwo gufata amazi, bukaba ari ingenzi cyane mu gukomeza gukora amarangi no gutwikira, cyane cyane mu gihe cyumye.
Guhuza: HEC irahujwe nubwoko butandukanye bwumuti, pigment, nibindi byongeweho, bigatuma bikwiranye nuburyo butandukanye.
Uburyo bwo gusaba
1. Kuvanga byumye
Uburyo bumwe busanzwe bwo kwinjiza HEC muburyo bwo gusiga irangi ni ukuvanga byumye:
Intambwe ya 1: Gupima ingano isabwa yifu ya HEC.
Intambwe ya 2: Buhoro buhoro ongeramo ifu ya HEC mubindi bice byumye bigize formulaire.
Intambwe ya 3: Menya neza kuvanga neza kugirango wirinde guhuzagurika.
Intambwe ya 4: Buhoro buhoro ongeramo amazi cyangwa umusemburo mugihe uvanze ubudahwema kugeza HEC yuzuye neza kandi imvange ya homogeneous igerwaho.
Kuvanga byumye birakwiriye gutegurwa aho hakenewe kugenzura neza ububobere bukenewe kuva mbere.
2. Gutegura igisubizo
Gutegura igisubizo cyimigabane ya HEC mbere yo kuyinjiza muburyo bwo gusiga irangi nubundi buryo bwiza:
Intambwe ya 1: Kata ifu ya HEC mumazi cyangwa igisubizo cyifuzwa, urebe ko uhora uhindagurika kugirango wirinde ibibyimba.
Intambwe ya 2: Emerera umwanya uhagije kugirango HEC ihindurwe neza kandi ishonga, mubisanzwe amasaha menshi cyangwa nijoro.
Intambwe ya 3: Ongeraho iki gisubizo cyibisubizo muburyo bwo gusiga irangi mugihe ukurura kugeza igihe ibyifuzo bihamye hamwe nibintu bigerwaho.
Ubu buryo butuma byoroha gukora no kwinjiza HEC, cyane cyane mubikorwa binini.
Ibitekerezo
1. Kwibanda
Ubwinshi bwa HEC busabwa muburyo bwo gusiga irangi buratandukanye bitewe nubushake bwifuzwa nuburyo bukoreshwa:
Porogaramu Ntoya-Shear Porogaramu: Kuri brush cyangwa roller progaramu, kwibanda kwa HEC (0.2-1.0% kuburemere) birashobora kuba bihagije kugirango ugere ku bwenge bukenewe.
Porogaramu-Shear Yinshi: Kubisabwa spray, kwibanda cyane (1.0-2.0% kuburemere) birashobora gukenerwa kugirango wirinde kugabanuka no kwemeza atomizasiyo nziza.
2. pH Guhindura
PH yo gushushanya irangi irashobora kugira ingaruka kumikorere no mumikorere ya HEC:
Icyiciro cyiza cya pH: HEC ikora neza muburyo butabogamye kuri alkaline nkeya pH (pH 7-9).
Guhindura: Niba formulaire ari acide cyane cyangwa alkaline, hindura pH ukoresheje inyongeramusaruro ikwiye nka ammonia cyangwa acide organic kugirango uhindure imikorere ya HEC.
3. Ubushyuhe
Ubushyuhe bugira uruhare runini muguhindura no gusesa HEC:
Ubukonje bw'amazi akonje: amanota ya HEC yagenewe gushonga mumazi akonje, ashobora koroshya inzira yo kuvanga.
Kwihuta kw'amazi ashyushye: Rimwe na rimwe, gukoresha amazi ashyushye birashobora kwihutisha inzira y’amazi, ariko ubushyuhe buri hejuru ya 60 ° C bugomba kwirindwa kugirango birinde kwangirika kwa polymer.
4. Guhuza nibindi bikoresho
HEC ikeneye guhuzwa nibindi bikoresho muburyo bwo gukora kugirango birinde ibibazo nko gukora gel cyangwa gutandukanya icyiciro:
Umuti: HEC irahuza na sisitemu zombi zishingiye ku mazi kandi zishingiye ku gukemura ibibazo, ariko hagomba kwitonderwa kugirango iseswa burundu.
Pigment and Fillers: HEC ifasha guhagarika pigment no kuzuza, kwemeza kugabana kimwe no gukumira gutura.
Ibindi Byongeweho: Kubaho kwa surfactants, dispersants, nibindi byongeweho birashobora kugira ingaruka kumyumvire no gutuza kwimyumbati ya HEC.
Inama zifatika zo gukoresha neza
Mbere yo gusenyuka: Mbere yo gushonga HEC mumazi mbere yo kuyongerera kumarangi irashobora gufasha gukwirakwiza kimwe no kwirinda guhuzagurika.
Buhoro buhoro Wongeyeho: Mugihe wongeyeho HEC muburyo bwo kubikora, kora buhoro kandi hamwe nubukangurambaga buhoraho kugirango wirinde kubyimba.
Kuvanga cyane-Shear Kuvanga: Koresha imvange-shear ivanze niba bishoboka, kuko bishobora gufasha kugera kubintu byinshi bivanze hamwe no kugenzura neza ububobere.
Guhindura Kwiyongera: Hindura icyerekezo cya HEC gahoro gahoro, ugerageze ibishishwa hamwe nibisabwa nyuma yinyongera kugirango ugere kubyo wifuza.
Ibibazo bisanzwe hamwe no gukemura ibibazo
Kuvunika: Niba HEC yongeweho vuba cyane cyangwa itavanze bihagije, irashobora gukora ibibyimba. Kugira ngo wirinde ibi, kwirakwiza HEC mumazi gahoro gahoro mugihe ukurura cyane.
Viscosity idahuye: Guhindagurika mubushuhe, pH, no kuvanga umuvuduko birashobora gushikana kumyuka idahuye. Buri gihe ukurikirane kandi uhindure ibipimo kugirango ukomeze uburinganire.
Ifuro: HEC irashobora kwinjiza umwuka muburyo bwo gukora, biganisha ku ifuro. Koresha defoamers cyangwa anti-ifuro kugirango ugabanye iki kibazo.
Hydroxyethyl selulose nikintu ntagereranywa mugushushanya amarangi no gutwikira bitewe nubushobozi bwayo bwo kongera ububobere, ituze, hamwe nibisabwa. Mugusobanukirwa uburyo bwiza bwo kwinjizamo HEC, guhindura ibipimo byerekana, no gukemura ibibazo bisanzwe, ababikora barashobora gukora ubuziranenge bwo hejuru, buhoraho, kandi bukoresha abakoresha amarangi. Haba binyuze mu kuvanga byumye cyangwa gutegura igisubizo, urufunguzo ruri mu kuvanga neza, guhindura pH, no kugenzura ubushyuhe kugirango ukoreshe neza inyungu za HEC.
