Mu gusiga amarangi, hydroxyethyl selulose (HEC) nigisanzwe kibyimbye hamwe na rheologiya ishobora guhindura uburyo bwo kubika neza, kuringaniza no kubaka amarangi. Kugirango wongere hydroxyethyl selulose kumarangi kandi urebe ko ikora neza, hagomba gukurikizwa ingamba zimwe na zimwe zo kwirinda. Inzira yihariye niyi ikurikira:
1. Ibyiza bya hydroxyethyl selile
Hydroxyethyl selulose ni polymer idafite amazi ya elegitoronike ifite umubyimba mwiza, gukora firime, kugumana amazi, guhagarika no kwigana. Bikunze gukoreshwa mumarangi ashingiye kumazi, ibifatika, ububumbyi, wino nibindi bicuruzwa. Iraboneka mugusimbuza igice cyamatsinda ya hydroxyl kumurongo wa selile ya selile hamwe na hydroxyethyl, bityo ikagira amazi meza.
Ibikorwa by'ingenzi bya HEC mu marangi ni:
Ingaruka yibyibushye: Ongera ubwiza bwirangi, wirinde irangi kugabanuka, kandi ugire ubwubatsi bwiza.
Ingaruka zo guhagarikwa: Irashobora gukwirakwiza no guhuza ibice bikomeye nka pigment hamwe nuwuzuza kugirango birinde gutura.
Ingaruka zo gufata amazi: Kongera amazi yo gufata amazi ya firime, kongera igihe cyo gufungura, no kunoza ingaruka zo gusiga irangi.
Igenzura rya rheologiya: hindura amazi kandi uringanize, kandi utezimbere ikibazo cya brush mugihe cyo kubaka.
2. Ongeraho intambwe za hydroxyethyl selulose
Intambwe ibanziriza guseswa Mubikorwa nyabyo, hydroxyethyl selulose igomba gukwirakwizwa neza kandi igashonga binyuze muburyo bwo gusesa. Kugirango umenye neza ko selile ishobora kugira uruhare rwayo rwose, mubisanzwe birasabwa kubanza kuyishonga mumazi, aho kuyongeraho neza. Intambwe zihariye nizi zikurikira:
Hitamo igisubizo gikwiye: mubisanzwe amazi ya deionion akoreshwa nkumuti. Niba hari andi mashanyarazi akoreshwa muri sisitemu yo gutwikira, ibintu byo gusesa bigomba guhinduka ukurikije imiterere yumuti.
Kunyunyuza buhoro hydroxyethyl selulose: Kunyunyuza buhoro kandi buringaniye ifu ya hydroxyethyl selulose mugihe ukurura amazi kugirango wirinde agglomeration. Umuvuduko ukurura ugomba gutinda kugirango wirinde kugabanya umuvuduko wa selile cyangwa gukora “colloide” kubera imbaraga zogosha cyane.
Iseswa rihagaze: Nyuma yo kuminjagira hydroxyethyl selulose, igomba gusigara ihagaze mugihe runaka (mubisanzwe iminota 30 kugeza kumasaha menshi) kugirango selile yabyimbye rwose kandi ishonga mumazi. Igihe cyo guseswa biterwa nubwoko bwa selile, ubushyuhe bwumuti hamwe nuburyo bukurura.
Hindura ubushyuhe bwo gusesa: Kongera ubushyuhe bifasha kwihutisha inzira yo gusesa hydroxyethyl selulose. Mubisanzwe birasabwa kugenzura ubushyuhe bwibisubizo hagati ya 20 ℃ -40 ℃. Ubushyuhe bukabije burashobora gutera selile kwangirika cyangwa kwangirika kwumuti.
Guhindura pH agaciro k'igisubizo Igisubizo cya hydroxyethyl selulose gifitanye isano rya bugufi na pH y'igisubizo. Ubusanzwe irashonga neza mugihe kidafite aho kibogamiye cyangwa alkaline nkeya, hamwe nagaciro ka pH hagati ya 6-8. Mugihe cyo gusesa, agaciro ka pH karashobora guhinduka wongeyeho ammonia cyangwa ibindi bintu bya alkaline nkuko bikenewe.
Ongeramo hydroxyethyl selulose igisubizo kuri sisitemu yo gutwikira Nyuma yo gusesa, ongeramo igisubizo kuri coating. Mugihe cyo kongeramo, bigomba kongerwaho buhoro kandi bigakangurwa ubudahwema kugirango habeho kuvanga bihagije na materique. Mugihe cyo kuvanga, birakenewe guhitamo umuvuduko ukwiye ukurikije sisitemu zitandukanye kugirango wirinde sisitemu kwangirika cyangwa kwangirika kwa selile kubera imbaraga zogosha cyane.
Guhindura ibishishwa Nyuma yo kongeramo hydroxyethyl selulose, ubwiza bwikibiriti burashobora kugenzurwa muguhindura umubare wongeyeho. Mubisanzwe, ingano ya hydroxyethyl selulose ikoreshwa iri hagati ya 0.3% -1.0% (ugereranije nuburemere bwuzuye bwa coating), kandi umubare wihariye wongeyeho ugomba guhindurwa mubigeragezo ukurikije ibisabwa kugirango ushireho. Umubare munini cyane wongeyeho urashobora gutuma igifuniko kigira ubukonje bwinshi kandi butemba neza, bikagira ingaruka kubikorwa byubwubatsi; mugihe inyongera idahagije ntishobora kuba ifite uruhare rwo kubyimba no guhagarikwa.
Kora ibizamini byo kuringaniza no kubika Nyuma yo kongeramo hydroxyethyl selulose no guhindura formulaire ya coating, imikorere yubwubatsi igomba kugeragezwa, harimo kuringaniza, sag, kugenzura ibimenyetso bya brush, nibindi. Mugihe kimwe, ikizamini cyo guhunika ububiko nacyo gisabwa kugirango witegereze imyanda ya coating nyuma yo guhagarara mugihe runaka, ihinduka ryijimye, nibindi, kugirango umenye ihame rya hydroxyethyl selile.
3. Kwirinda
Irinde agglomeration: Mugihe cyo gusesa, hydroxyethyl selulose iroroshye cyane kwinjiza amazi no kubyimba, bityo rero igomba kuminjagira mumazi gahoro gahoro kandi ikemeza ko ihagije kugirango irinde ibibyimba. Iyi ni ihuriro ryingenzi mubikorwa, bitabaye ibyo birashobora kugira ingaruka ku gipimo cyo gusesa no guhuza.
Irinde imbaraga zogosha cyane: Mugihe wongeyeho selile, umuvuduko ukabije ntugomba kuba mwinshi kugirango wirinde kwangiza urunigi rwa selile bitewe ningufu zogosha cyane, bikaviramo kugabanuka kwimikorere yabyo. Byongeye kandi, mu musaruro ukurikiraho wo gutwikira, gukoresha ibikoresho byogosha cyane nabyo bigomba kwirindwa bishoboka.
Kugenzura ubushyuhe bwo gusesa: Iyo ushonga hydroxyethyl selulose, ubushyuhe bwamazi ntibugomba kuba hejuru cyane. Mubisanzwe birasabwa kubigenzura kuri 20 ℃ -40 ℃. Mugihe cy'ubushyuhe bwo hejuru, selile irashobora kwangirika, bigatuma igabanuka ryingaruka zayo nubukonje.
Kubika igisubizo: Hydroxyethyl selulose ibisubizo mubisanzwe bigomba gutegurwa no gukoreshwa ako kanya. Ububiko bwigihe kirekire buzagira ingaruka kubwiza no guhagarara neza. Mubisanzwe birasabwa gutegura igisubizo gikenewe kumunsi wo gukora amarangi kugirango ukomeze imikorere myiza.
Kwiyongera kwa hydroxyethyl selulose kumarangi ntabwo ari uburyo bworoshye bwo kuvanga umubiri gusa, ahubwo bigomba no guhuzwa nibisabwa mubikorwa hamwe nibikorwa byihariye kugirango harebwe niba kubyimba, guhagarika no kubika amazi byakoreshejwe neza. Mugihe cyo kongeramo, witondere intambwe ibanziriza guseswa, kugenzura ubushyuhe bwo gusesa nagaciro ka pH, hamwe no kuvanga byuzuye nyuma yo kongerwaho. Ibisobanuro birambuye bizagira ingaruka kumiterere no gukora neza kurangi.
