Hydroxyethyl selulose (HEC) ni amazi-ashonga adafite ionic selulose ether. Ikoreshwa cyane mumazi ashingiye kumazi kubera kubyimbye kwiza, kwigana, gukora firime no guhagarika ibintu. Nkibyimbye hamwe na stabilisateur mubitambaro, HEC irashobora kunoza cyane imiterere ya rheologiya hamwe no gusiga irangi.
1. Ibikorwa byingenzi bya hydroxyethyl selulose
Mu mazi ashingiye ku mazi, ibikorwa by'ingenzi bya HEC bigaragarira mu bice bikurikira:
Ingaruka yibyibushye: HEC ifite ubushobozi bukomeye bwo kubyimba, bushobora kunoza neza ubushobozi bwimitsi nubushobozi bwo guhagarika amazi ashingiye kumazi kandi bikarinda pigment hamwe nuwuzuza muri kote.
Kunoza imvugo: HEC irashobora guhindura amazi mumazi ashingiye kumazi kugirango igaragaze ubukonje buke munsi yimisatsi miremire, bigatuma byoroha gukwirakwira mugihe ushushanya, mugihe ugaragaza ububobere buke mubihe bihamye, bityo bikagabanya umuvuduko w irangi. kumanika ibintu.
Iterambere ryongerewe imbaraga: HEC ifite ubukana bwiza bwo gukonjesha no guhunika neza, bishobora kongera igihe cyigihe cyo gutwikira kandi bigaharanira umutekano mubidukikije bitandukanye.
Kunoza imitunganyirize ya firime: HEC ikora firime ihindagurika nyuma yo gusiga irangi ryumye, kongera imbaraga no kwambara birwanya firime irangi no kunoza imikorere yo kurinda irangi.
2. Uburyo bwo gukoresha HEC
Iyo ukoresheje HEC mumazi ashingiye kumazi, uburyo bwo gutatanya no gusesa hamwe nuburyo bwo kongeramo ubundi bukoreshwa. Ibikurikira nuburyo bwihariye bwo gukoresha:
() 1. Kwitegura gusesa HEC
HEC ni ifu igoye gushonga mu buryo butaziguye kandi byoroshye gukora ibibyimba mumazi. Kubwibyo, mbere yo kongeramo HEC, birasabwa kubanza kuyitatanya. Intambwe zisanzwe nizi zikurikira:
Kangura no gutatanya: Buhoro buhoro ongeramo HEC mumazi munsi yumuvuduko muke kugirango wirinde kwibumbira hamwe. Umubare wa HEC wongeyeho ugomba guhindurwa ukurikije ibisabwa bya viscosity bisabwa, muri rusange bingana na 0.3% -1% bya formula yose.
Irinde guteka: Iyo wongeyeho HEC, umubare muto wibikoresho birwanya keke, nka Ethanol, propylene glycol, nibindi, birashobora kongerwaho mumazi kugirango ifu ya HEC ikwirakwizwe neza kandi bigabanye amahirwe yo guteka.
(2). Uburyo bwo gutatanya no gusesa
Uburyo bwo gukwirakwiza no gusesa ni ugushonga HEC ukwayo mumazi ya viscous mugihe cyo gutegura irangi, hanyuma ukayongeramo irangi. Intambwe zihariye nizi zikurikira:
Uburyo bwo gusesa: HEC iragoye gushonga mubushyuhe busanzwe cyangwa buke, bityo amazi arashobora gushyuha uko bikwiye kugirango agere ku bushyuhe bwa 30-40 ° C kugirango yihutishe iseswa rya HEC.
Igihe cyo gukurura: HEC irashonga buhoro kandi mubisanzwe bisaba gukurura amasaha 0.5-2 kugeza igihe bishonge burundu mumazi meza cyangwa yoroheje.
Guhindura agaciro ka pH: HEC imaze guseswa, agaciro ka pH k'igisubizo karashobora guhindurwa ukurikije ibikenewe, mubisanzwe hagati ya 7-9, kugirango urusheho gukomera.
(3). Uburyo bwongeyeho
Uburyo bwo kongeramo butaziguye ni ukongera HEC muri sisitemu yo gutwikira mugihe cyo gutunganya ibicuruzwa, bikwiranye no gutwikira hamwe nibisabwa bidasanzwe. Nyamuneka nyamuneka witondere ingingo zikurikira mugihe ukora:
Kuma mbere hanyuma utose: OngerahoHECkubice byumye by'irangi rishingiye kumazi ubanza, ubivange neza hamwe nandi mafu, hanyuma wongeremo amazi nibice byamazi kugirango wirinde agglomeration.
Igenzura ryogosha: Iyo wongeyeho HEC mugipfundikizo, birakenewe gukoresha ibikoresho bivanga-byogosha cyane, nka disikuru yihuta, kugirango HEC ishobore gukwirakwira neza mugihe gito kandi igere kubwiza bukenewe.
3. Kugenzura dosiye ya HEC
Mu mazi ashingiye ku mazi, ingano ya HEC igomba kugenzurwa ukurikije ibikenewe bifatika. HEC cyane izatera ibishishwa hejuru cyane kandi bigira ingaruka kumikorere; bike cyane HEC ntishobora kugera kubikorwa byateganijwe. Mubihe bisanzwe, dosiye ya HEC igenzurwa kuri 0.3% -1% ya formula yose, kandi igipimo cyihariye gishobora guhinduka binyuze mubushakashatsi.
4. Kwirinda HEC muburyo bushingiye kumazi
Irinde agglomeration: HEC ikunda guhuriza hamwe mumazi, mugihe rero uyongeyeho, uyongereho gahoro gahoro gashoboka, uyatatanye neza, kandi wirinde kuvanga umwuka bishoboka.
Ubushyuhe bwo gusenyuka: HEC ishonga vuba ku bushyuhe bwo hejuru, ariko ubushyuhe ntibugomba kurenga 50 ° C, bitabaye ibyo ubwiza bwabwo bushobora kugira ingaruka.
Ibintu bikurura: Birakenewe guhora bisabwa mugihe cyo gusesa kwa HEC, kandi ibikoresho bifite ibipfundikizo bigomba gukoreshwa ibishoboka byose kugirango hirindwe kwanduzwa n’umwanda wo hanze no guhumeka amazi.
Guhindura agaciro ka pH: Ubukonje bwa HEC buziyongera mugihe cya alkaline, bityo agaciro ka pH k'igisubizo gakeneye guhinduka muburyo bukwiye kugirango imikorere yimyenda itagabanuka kubera pH ikabije.
Ikizamini cyo guhuza: Mugihe utegura formulaire nshya, imikoreshereze ya HEC igomba kugeragezwa kugirango ihuze nibindi binini, emulisiferi, nibindi kugirango harebwe ko nta reaction mbi zizabaho.
5. Koresha ingero za HEC mumazi ashingiye kumazi
HEC irashobora gukoreshwa nkibyimbye haba mumazi yimbere yimbere yimbere hamwe namazi ashingiye kumazi. Urugero:
Irangi ryamazi ashingiye kumbere: HEC ikoreshwa mugutezimbere irangi ryirangi, bigatuma porogaramu yoroshye ndetse nibindi byinshi, no kugabanya ibimenyetso bya brush.
Uruzitiro rushingiye ku mazi rushingiye ku mazi: HEC irashobora kongera imbaraga zo guhangana n’imihindagurikire y’ikirere kandi ikirinda kwangirika kwa firime yatewe n’isuri.
Ikoreshwa rya HEC mu mazi ashingiye ku mazi ntirishobora gusa kunoza imikorere yubwubatsi, ariko kandi rinazamura ubwiza bugaragara nigihe kirekire cya firime. Mubikorwa bifatika, ukurikije ibisabwa byihariye byo gutwikirwa, uburyo bwo gusesa hamwe n’inyongera ya HEC byatoranijwe neza, kandi bigahuzwa no gutegura ibindi bikoresho fatizo, ingaruka nziza zo gutwikira zishobora kugerwaho.
