I-Peect Ibanga le-hec

Inqanaba lepeyintiI-hec hydroxythyl seluplose luhlobo lwe-polymer ye-ionic enganyibiliki, emhlophe okanye etyheli, kwaye i-odols, kunye nexabiso lokuchitha iqondo lokushisa, ngokubanzi izinyibilikisi. Inozinzo ze-hleko oluhle kunye notshintsho oluncinci lwe-viscofity kuluhlu lwe-ph2-12. I-hec inayo i-HATE YOKHUSELEKO NOBUCHULE, kwaye inogcino lwamanzi olomeleleyo lwe-hydrophilic. Isisombululo se-AICOOOFIO ENYE Inomsebenzi womphezulu kunye neemveliso eziphezulu ze-viscosity zine-pseudoplasticity ephezulu. Unokwenziwa kwifilimu ebonakalayo efihlakeleyo enamandla aphakathi, akachukunyiswanga yioyile, engachaphazelekanga kukukhanya, kusekho ifilimu enyibilikiswe amanzi. Emva konyango oluphezulu, ii-hec zasasazeka kwaye azithethi emanzini, kodwa ziyanyibilika kancinci. I-PH inokuhlengahlengiswa ukuya kwi-8-10 kwaye ikhawuleza inyibilike.

Eyona ndawo iphambili

HYDROXYETHTHle(Hec)Ngaba kukuba ingachithwa kumanzi abandayo kunye namanzi ashushu, kwaye ayinazimpawu zejell. Inoluhlu olubanzi lokufakwa endaweni, ukuluka kunye nokujonga. Inozinzo oluhle lobushushu (ngaphantsi kwe-140 ° C) kwaye ayivelisi phantsi kweemeko ze-acidic. ukuvavanywa. Isisombululo se-hydroxythl seluplose (hec) inokwenza ifilimu ebonakalayo, enezinto ezingezizo ze-ionic ezingasebenzi ngee-Ion kwaye zibe nokuhambelana kakuhle.

Njenge-colloid ye-colloid, i-hec ye-Peect ye-Peec inokusetyenziselwa i-vinyl ye-vinyl ye-vinyl ye-vinyl ye-eullion yokuphucula uzinzo lwenkqubo yePolymerizazazazazazazazazazazazazazazazazazali kububanzi be-PORMER. Kwimveliso yeemveliso ezigqityiweyo ukwenza i-pigment, i-fililler kunye nezinye izongezelelo zisasazeke ngokulinganayo, zizinzile kwaye zibonelela ngefutha. Ingasetyenziselwa i-styrene, i-Acrylic, i-Acrylic kunye nezinye iiplellys ezinqunyanyisiweyo, zisetyenziswa kwipeyinti ye-Latex inokuphucula kakhulu ukuntywila, ukuphucula ukusebenza.

Indlela yesicelo se-hydroxyEtheethyl secuplose hec kwi-materborgneipeyinti

1. Yongeza ngokuthe ngqo xa i-pignment yokugaya: Le ndlela yeyona ilula, kwaye ixesha elisetyenzisiweyo lifutshane. Amanyathelo aneenkcukacha ngolu hlobo lulandelayo:

.

(2) Qalisa ukuvuselela ngesantya esisezantsi kwaye ngokuthe ngcembe wongeza i-hydroxyyl

(3) Qhubeka nokuvuselela kude kufike khona onke amasuntswana

.

.

I-2. Ilungiselelwe kunye ne-Galue Lile: Le ndlela ixhotyiswe ngokuqala yolwelo olugqibeleleyo lolwelo, kwaye yongeza ngokuthe ngqo kwimveliso yepeyinti, kodwa kufuneka igcinwe ngokuchanekileyo . Amanyathelo kunye neendlela ziyafana nangamanyathelo (1) - (4) kwi-1, ngaphandle kokuba umotor onqabileyo akafuneki kwaye kuphela i-agitotor kuphela ene-hydroxyyl fibers ekusasazeni kwanele. Qhubeka nokuvuselela kude kufikelele ngokupheleleyo kwisisombululo esincinci. Qaphela ukuba i-themilthew inhibitor kufuneka yongezwe kwinkosi yotywala ngokukhawuleza.

I-3. I-Porridges njenge-phenology: Ekubeni izinyibilikisi ezimbi zizinto ezimbi ze-hydroxyteethyl sellyulose, ezi zinyibilikisi zinokuxhotyiswa nge-porridgege. Ezona ziqhobileyo zezinto ezisetyenziswayo zisetyenziswa njenge-galylene glycol, i-propylene glylcol, kunye ne-hexadecanol ye-prolyl ye-ocevate), amanzi omkhenkce ahlala esetyenziswa ngolwelo olusebenzayo kwi-porridge. I-Gruel-Njenge-hydroxyythl seluplose yongezwa ngokuthe ngqo kwipeyinti. I-HydroxyEtheetheetheetheetheetheetheethl igcwalisiwe kwifom yePoritri. Emva kokongeza i-lacquer, inyibilikisa ngoko nangoko kwaye ube nefutha. Emva kongeziweyo, qhubeka uxhokonxa de i-hydroxythyl ichithwe ngokupheleleyo kunye neyunifomu. I-porridge eqhelekileyo yenziwa ngokuxuba iinxalenye ezintandathu ze-organic solvent okanye amanzi e-ice enenxalenye enye ye-hydroxyyethyl seluplose. Emva kwemizuzu emi-5 ukuya kwengama-30, ibanga lepeyintiHecI-hydrolyzes kwaye ikhuphuka iphuma. Ehlotyeni, umswakama wamanzi uphezulu kakhulu ukuba ungasetyenziselwa i-PORPridge.

PUkuphinda uphinda kwakhona

I-1 ngaphambi nasemva kokongeza ibanga lepeyintiHec, kufuneka ibonwe ngokuqhubekayo kude kube selucace gca kwaye icacile.

I-2. Silisa i-hydroxythyl seluplose kwitanki lokuxuba kancinci. Sukumongeza kwitanki yokuxuba ngamaxabiso amakhulu okanye ngqo kwiBanga le-BulkHec.

I-3 iqondo lobushushu lamanzi kunye nexabiso le-pH linoluhlobo olucacileyo lokupheliswa kwenqanaba lepeyintiHecI-Hydroxyyl sellulose, ke kufuneka kuthathelwe ingqalelo kuyo.

Musa ukongeza into esisiseko kumxube ngaphambi kwenqanaba lepeyintiHecI-HydroxyEtheetheetheetheetheetheetheetheethl seluplose ifakwe ngamanzi. Ukuphakamisa i-pH emva kokufika kunceda ukunyibilikisa.

I-5 .Amaxesha amaninzi, ukongeza okuqala kweMildew inhibitor.

6 Xa usebenzisa iBanga le-Viscofity ephezuluHec, Ukugxininiswa kotywala botywala akufuneki kube ngaphezulu kwe-2,5-3% (ngokobunzima), kungenjalo utywala botywala kunzima ukusebenza.

Izinto ezichaphazela i-viscofity yepeyinti ye-Latex

1.I-fubble ye-fubbs entsalela amaninzi kwipende, okuphezulu.

2.Isixa semali ye-argator kunye namanzi kwifomula yokupeyinta?

I-3 kwi-synthesis ye-Latex, i-catalyst ye-Oxide ye-Oxide yeXesha leSixa.

4. Umthamo wezinye izinto zendalo kwifomula yepeyinti kunye nomyinge we-dosioge enebanga lepeyintiHec.)

5. Inkqubo yokwenza ipeyinti, iodolo yamanyathelo ekufuneka yongeze i-thuckere ifanelekile.

6.Umntu wokuphazamiseka okugqithisileyo kunye nokufuma kakhulu ngexesha lokusasazeka.

7.Imibala yokukhukuliseka kwe-tickener.
