Hydroxyethyl cellulose hauv emulsion xim

Daim ntawv thov txoj kev ntawm hydroxyethyl cellulose hauv looj cov xim khov

1. Hydroxyethyl cellulose nrog porridge nyiam phenology: vim tias cov kuab tshuaj hauv cov organic, qee cov kuab tshuaj uas tuaj yeem siv tau los ua cov porridge. Dej khov dej kuj yog cov tshuaj tsis zoo, yog li nws feem ntau siv hauv porridge nrog cov organic kua. Lub hydroxyethyl cellulose ntawm Conge daim ntawv tuaj yeem txuas ncaj qha rau hauv emulsii pleev xim. Hydroxyethyl cellulose tau muab noo nyob hauv daim ntawv porridge daim ntawv. Thaum ntxiv rau cov xim, nws nrawm nrib thiab tuab. Khaws stirring kom txog thaum hydroxyethyl cellulose yog tag nrho dispersed thiab yaj. Ib txwm porridge yog ua los ntawm kev sib tov rau feem rau feem ntawm organic kuab tshuaj lossis dej khov nrog ib feem ntawm hydroxyethyl cellulose. Tom qab txog 5-30 feeb, lub hydroxyethyl cellulose hydrolyzes thiab pom tseeb sawv. (Nws tau pom zoo tias cov cua noo ntawm cov dej nyob rau lub caij ntuj sov dhau lawm yuav siv rau porridge.)

2. Ntxiv hydroxyethyl cellulose ncaj qha rau kev sib tsoo xim xim: hom no yooj yim thiab lub sijhawm luv. Cov ncauj lus kom ntxaws yog raws li hauv qab no:

(1) Ntxiv cov dej ntshiab kom tsim nyog nyob rau hauv lub vat ntawm siab yuav tsum txiav agitator (feem ntau, zaj duab xis tsim additives thiab cov neeg sawv cev ntub dej ntxiv rau lub sijhawm no)

(2) Pib kom do ntawm qis ceev yam tsis tau nres thiab maj mam ntxiv hydroxyethyl cellulose tusyees

(3) Txuas ntxiv mus kom txog thaum txhua qhov me me tawg thiab soaked

(4) Ntxiv cov inhibitoritor thiab kho tus nqi pH

(5) Do kom txog thaum txhua hydroxyethyl cellulose yog tag nrho cov kev daws teeb meem nyob rau hauv cov mis, thiab zom kom txog thaum nws pleev xim.

3 Hydroxyethyl cellule nrog niam kua tos: cov qauv no yog hloov kho cov xim ntau dua, thiab tom qab ntawd ntxiv cov xim tiav khoom, tab sis kom muaj kev cia siab. Cov kauj ruam thiab cov hau kev zoo ib yam li cov kauj ruam (1) - (4) Txuas ntxiv nplawm kom txog thaum nws dissolves rau hauv cov tshuaj tuab. Nco ntsoov tias: Antimiffirasen Tus neeg sawv cev yuav tsum tau ntxiv kom sai li sai tau hauv cov xim cawv niam haus cawv.

4 Cov teeb meem xav tau mloog thaum equipping hydroxyethyl cellulose niam cawv

Txij li hydroxyethyl cellulose yog kho cov hmoov av granular, nws yog qhov yooj yim los tuav thiab yaj hauv dej nrog cov kev ceev faj hauv qab no.

(1) Ua ntej thiab tom qab ntxiv hydroxyethyl cellulose, yuav tsum ua kom nplawm, kom txog rau thaum txoj kev daws teeb meem tau meej thiab meej.

(2) Nws yog ib qho tsim nyog los sab cib lub cellonyethyl cellulose rau hauv tank tank maj mam. Tsis txhob ntxiv nws hauv cov khoom loj lossis ncaj qha rau hauv lub tankring.

(3) solubility ntawm hydroxyethyl cellulose yog qhov tseeb hais txog kub thiab siv tus nqi ntawm dej, yog li tshwj xeeb mloog yuav tsum tau them rau nws.

(4) Tsis tas ntxiv qee cov tshuaj uas yooj yim rau cov sib tov ua ntej hydroxyethyl cellulose hmoov yog tsau nrog dej. Tsa phua tom qab soaking pab yaj.

(5) kom deb li deb tau, kev sib ntxiv ntxov, ntawm cov neeg ua kom tus inhibitor.

(6) Thaum siv cov viscosity hydroxyethyl cellulose, lub concentration ntawm niam cawv yuav tsum tsis txhob siab dua 2.5-3% (los ntawm cov cawv), tsis muaj leej niam haus cawv yog qhov nyuaj rau kev ua haujlwm.

Yam cuam tshuam rau cov viscosity ntawm cov xim huv:

(1) Vim tias muaj kev nplawm zoo heev thiab muaj cov av noo ntau thaum dispersing.

(2) Tus nqi ntawm lwm tus neeg cov ntoo thickeners hauv cov xim xim thiab cov feem ntawm tus nqi nrog hydroxyethyl cellulose.)

(3) tus nqi ntawm cov khoom ua si saum npoo thiab dej hauv cov xim xim sib xws ib yam nkaus.

(4 nyob rau hauv synthesis ntawm latex, residual catalyst oxide cov ntsiab lus ntawm tus lej.

Microbial yis ntawm tuab.

6 Nyob rau hauv cov txheej txheem ntawm kev pleev xim, qhov kev txiav txim ntawm cov kauj ruam ntxiv cov thickener yog qhov tsim nyog.

Qhov ntau tshaj tawm cov pa npuas hauv cov xim, cov viscosity siab dua
