Upende webanga le-hec

Ibanga lokupendaUHec HyrdloxyEthyl celtulose uhlobo lwe-polymer olungenazo amanzi, olumhlophe noma oluphuzi, okulula ukugeleza, kungabi nambiwa ngamazinga okushisa, ngokuvamile kukhuphuka nge-organic eningi, ngokuvamile izixazululo. Inokuqina okuhle kwe-PH nokushintshwa okuncane kwe-viscosity ebangeni le-PH2-12. I-HEC inokumelana nosawoti okuphezulu kanye nekhono le-hygroscopic, futhi inomgcini wamanzi we-hydrophilic oqinile. Isixazululo saso samanzi sinomsebenzi ongaphezulu kanye nemikhiqizo ephezulu yokubonana ine-pseudoplastity ephezulu. Kungenziwa ngefilimu ebonakalayo esobala enamandla alinganiselayo, ayingcoliswe kalula ngamafutha, ayithintwa ukukhanya, namanje inefilimu elinyibilikisiwe lamanzi. Ngemuva kokwelashwa okungaphezulu, i-HEC isabalalisa futhi ayihlanganisi emanzini, kepha inciphise kancane. I-PH ingashintshwa ibe ngu-8-10 futhi isheshe incibilize.

Izakhiwo Eziyinhloko

Hydroxyethyl cellulose(I-HEC)Ngabe lokho kungachithwa emanzini abandayo namanzi ashisayo, futhi akunazimpawu zejeli. Inobubanzi bokufaka esikhundleni sakwa-EXPERATIORUTIOL, SOLUBLITIENT NEVUSTION. Inokuqina okuhle okushisayo (ngaphansi kwe-140 ° C) futhi akukhiqizi ngaphansi kwezimo ze-acidic. ukuhanjiswa kwezulu. Isixazululo se-Hydroxyethyllll (HEC) singakha ifilimu esobala, enezici ezingezona ezingezona izici ezingahambisani nama-ion futhi zinokuhambisana okuhle.

Njenge-colloid evikela i-colloid, i-peint grade hec ingasetshenziselwa i-vinyl acetate emulzerization ukwenza ngcono ukuqina kohlelo lwe-polymerization ngobubanzi be-PH. Ekwenzeni imikhiqizo eqediwe ukwenza i-pigment, i-filler nezinye izengezo ezihlakazeke ngokulinganayo, zizinze futhi zinikeze umphumela wokuqina. Ingasetshenziselwa futhi i-styrene, acrylic, acrymer kanye nezinye ama-polymers amisiwe njengabahlakazayo, esetshenziswa ku-latex paint ingathuthukisa kakhulu ukuqina, ukuthuthukisa ukusebenza kwezinga.

Ukucaciswa kwe-CHCIAL

Indlela yohlelo lokusebenza ye-Hydroxyethyl cellulose Hec in Waterlernependa

1. Faka ngqo lapho ugaya u-pigment: Le ndlela ilula kakhulu, futhi isikhathi esisetshenzisiwe sifushane. Izinyathelo ezinemininingwane zimi ngalendlela elandelayo:

.

(2) Qala ukushukumisa ngejubane eliphansi futhi kancane kancane engeza i-hydroxyethyl cellulose

(3) Qhubeka nokuvusa kuze kube yilapho zonke izinhlayiya zimanzi

(4) Ngeza i-hlobo invibitor, umlawuli we-PH, njll

.

2 . Izinyathelo nezindlela zifana nezinyathelo (1) - (4) in Methodway 1, ngaphandle kwalapho umgadli wokusika ophezulu awudingeki futhi kuphela onamandla onamandla ane-hydroxyethyl ukuze ahlakazeke kahle kwikhambi kwanele. Qhubeka uvuse kuze kube yilapho kuncibilika ngokuphelele kwikhambi eliminyene. Qaphela ukuthi invibitor ye-hlobo kufanele ingezwe kuphuzo lotshwala ngokushesha ngokushesha okukhulu.

3 I-solvents esetshenziswa kakhulu efana ne-ethylene glycol, i-plylene glycol, kanye ne-hexadecanol (njenge-hexadecanol noma i-diethylene glycol buyl acetate) futhi amanzi eqhwa avame ukusetshenziswa ngoketshezi lwe-organic ephalilini. I-Gruel - njenge-Hydroxyethyl cellulose ingangezwa ngqo kupende. I-Hydroxyyethyl celtulose igcwele nge-porridge yafomu. Ngemuva kokungeza i-lacquer, chaza ngokushesha futhi ube nomphumela wokuqina. Ngemuva kokungeza, qhubeka ukuvusa kuze kube yilapho i-hydroxyethyl cellulose ichithwe ngokuphelele futhi iyunifomu. Iphalishi elijwayelekile lenziwa ngokuxuba izingxenye eziyisithupha ze-organic solvent noma amanzi eqhwa ngengxenye eyodwa ye-hydroxyethyl cellulose. Ngemuva kwemizuzu engaba ngu-5-30, ibanga lokupendaI-HECAma-hydrolyzes futhi avikelekile. Ehlobo, umswakama wamanzi uphakeme kakhulu ukuthi uzosetshenziselwa iphalishi.

I-4. Abathakathi badinga ukunakwa lapho behlobisa i-hydroxyethyyl cellulose mama wophuzo:

Pukwamukelaka

1 ngaphambi nangemva kokungeza ibanga lokupendaI-HEC, kumele ivuswe ngokuqhubekayo kuze kube yilapho ikhambi lisobala ngokuphelele futhi licacile.

2 Ungayingezi ethangini lokuxuba ngamanani amakhulu noma ngqo ebangeni elinobuningi noma elinama-sphericalI-HEC.

Amazinga ama-3 wamanzi nenani lamanzi anokubumbana okusobala kokuchithwa kwebanga lokupendaI-HECIHydroxYethyl Cellulose, ngakho-ke ukunakwa okukhethekile kufanele kukhokhwe kuwo.

Ungangezi okuthile okuyisisekelo kwengxube ngaphambi kwebanga lokupendaI-HECI-Hydroxyyethyl cellulose powder ifakwe emanzini. Ukukhulisa i-PH ngemuva kokuthambisa kusiza ukuncibilikisa.

I-5 .Akusemandleni ngangokunokwenzeka, ukungezwa kokuqala kwe-hlobo invibitor.

6 Lapho usebenzisa i-Pintcu yokupenda ebonakalayo ephezuluI-HEC, ukugcwala kotshwala bamama akufanele kube ngaphezulu kuka-2,5-3% (ngesisindo), ngaphandle kwalokho kunzima ukusebenza ngotshwala.

Izici ezithinta ukubonakala kopende we-latex

1.I-bubble yomoya ebethekile ependweni, kuphakama i-viscosity.

2.Inani le-activator namanzi ngendlela yokupenda elingaguquguquki?

3 ekusekeleni kwe-latex, okusalayo kwe-catalyst oxide axide yenani.

4. Umthamo wabanye abakhulu bemvelo kwifomula yokupenda kanye nesilinganiso semithamo nebanga lokupendaI-HEC.)

5.Kunqunyelwe inqubo yokwenza upende, ukuhleleka kwezinyathelo okufanele ukwengeza ubukhulu kufanelekile.

6.Due ekukhuleke ngokweqile kanye nomswakama owedlulele ngesikhathi sokuhlakazeka.

I-7.microbial ukuguguleka komkhulu.
