Xim qib hec

Kas xim qibHEC Hydroxyethyl cellulose yog ib hom dej tsis-ionic-soluble polymer, feem ntau yog tsis muaj peev xwm ua rau kub thiab txias, feem ntau insoluble hauv feem ntau cov organic cov kuab tshuaj. Nws muaj zoo p muaj kev ruaj khov thiab me viscosity hloov nyob rau hauv ntau yam ntawm PH2-12. HEC muaj cov ntsev ntau tsis kam thiab hygroscopic muaj peev xwm, thiab muaj zog hydrophilic dej khaws cia. Nws cov kev daws teeb meem aqueous muaj cov dej num nto thiab cov viscosity siab muaj pseudoplastic. Tuaj yeem ua rau hauv anhydous pob tshab cov yeeb yaj kiab nrog lub zog nruab nrab, tsis cuam tshuam los ntawm lub teeb, tseem muaj hec dej-soluble zaj duab xis. Tom qab kev kho deg, hec disperses thiab tsis sib sau ua ke hauv dej, tab sis yaj maj mam. Cov pH tuaj yeem hloov kho rau 8-10 thiab sai sai dissolves.

Cov khoom tseem ceeb

Hydroxyethyl cellulose(HEC)Yog tias nws tuaj yeem raug ntiab tawm hauv dej txias thiab dej kub, thiab tsis muaj GEL cov yam ntxwv. Nws muaj ntau yam hloov chaw, solubility thiab viscosity. Nws muaj zoo thermal ruaj khov (hauv qab 140 ° c) thiab tsis tsim cov khoom muaj acidic. nag lossis daus. Cov tshuaj hydroxyethyl cellulose (HEC) kev daws teeb meem tuaj yeem tsim cov yeeb yaj kiab hauv pob tshab, uas tsis muaj ionic cov yam ntxwv uas tsis cuam tshuam nrog ion thiab muaj kev sib haum zoo.

Ua kev tiv thaiv kev tiv thaiv kev tiv thaiv, xim qib HEC tuaj yeem siv rau Vinyl acetate emulsion polulsion los txhim kho cov polymerization hauv xovtooj dav. Nyob rau hauv kev tsim cov khoom tiav los ua kom muaj xim xim, muab tub lim thiab lwm yam kev sib ntxiv tusyees ayly dispersed, ruaj khov thiab muab cov nyhuv tuab. Nws kuj tseem siv tau rau STyrene, Acrylic thiab lwm cov xim txawv, siv hauv cov xim looj roj hmab tuaj yeem txhim kho kev ua haujlwm tuab, txhim kho kev ua haujlwm levening.

Daim ntawv thov txoj kev ntawm hydroxyethyl cellulose hec nyob rau hauv dejxim

1. Ntxiv rau qhov ncaj qha thaum sib tsoo xim: hom no yog qhov yooj yim tshaj plaws, thiab lub sijhawm siv yog luv. Cov kauj ruam kom ntxaws yog raws li hauv qab no:

(1) Ntxiv cov dej uas tsim nyog kom tsim nyog rau hauv VAT ntawm cov neeg ua haujlwm siab (feem ntau, ethylene glycol, ntub dej tus neeg sawv cev thiab ua yeeb yaj duab sib sau tus neeg sawv cev yog ntxiv rau lub sijhawm no)

(2) Pib stirring ntawm qhov nrawm nrawm thiab maj mam ntxiv hydroxyethyl cellulose

(3) Txuas ntxiv mus kom txog thaum txhua qhov me me yog tsau

(4) Ntxiv me me mildew inhibitor, Ph Regulator, thiab lwm yam

(5) do kom txog thaum txhua hydroxyethyl cellulose yog tag nrho cov kev daws teeb meem (lub viscosity ntawm kev ntxiv lwm cov hauv cov mis, thiab zom kom txog thaum nws pleev xim.

2. Nruab nrog niam kua muag tos: Cov qauv no yog ua tiav nrog cov qauv kua txiv, tuaj yeem txuas ncaj qha ntxiv rau cov khoom tiav, tab sis yuav tsum muaj kev cia Cov. Cov kauj ruam thiab cov hau kev zoo ib yam li cov kauj ruam (1) - (tsuas yog qee tus neeg mob siab kom muaj lub zog ua kom muaj zog los ua kom cov hydroxyethyl fibers ensy dispersed hauv kev daws tau txaus. Txuas ntxiv nplawm kom txog thaum nws dissolves rau hauv cov tshuaj tuab. Nco ntsoov tias tus neeg inhibitor yuav tsum tau ntxiv rau niam cawv niam hmo kom sai li sai tau.

3. Porridge nyiam phenology: Vim tias organic cov kuab tshuaj rau hydroxyethyl cellulose, cov organic cov kuab tshuaj tuaj yeem nruab nrog porridge. Feem ntau siv cov ethylene glycolent cov neeg sawv cev, thiab ua yeeb yaj kiab tsis zoo nrog cov kua dej tsis zoo nrog cov kua txiv kab ntxwv hauv porridge. Gruel - zoo li hydroxyethyl cellulose tuaj yeem txuas ncaj qha ntxiv rau cov xim. Hydroxyethyl cellulose tau muab noo nyob hauv daim ntawv porridge daim ntawv. Tom qab ntxiv lacquer, yaj tam sim ntawd thiab muaj cov nyhuv tuab. Tom qab ntxiv, txuas ntxiv mus do kom txog thaum hydroxyethyl cellulose kom yaj thiab niaj hnub. 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, qib ximTus pahydrolyzes thiab pom tau pom. Nyob rau lub caij ntuj sov, cov av noo ntawm cov dej yog qhov siab dhau lawm yuav siv rau porridge.

4 .Qhov xav tau kev saib xyuas thaum equipping hydroxyethyl cellulose niam cawv:

Pkev txais nyiaj

1 ua ntej thiab tom qab ntxiv xim qibTus pa, yuav tsum tau ua kom nruj tsis tu ncua kom txog thaum cov kev daws teeb meem tau meej thiab meej.

2. Sab cib lub hydroxyethyl cellulose mus rau hauv lub tank sib xyaw. Tsis txhob ntxiv nws rau hauv lub tank sib xyaw hauv cov khoom loj lossis ncaj qha rau hauv cov xim lossis khau khiab ximTus pa.

3 Dej kub thiab pH nqi ntawm dej muaj piv rau kev sib cais ntawm qib xim qibTus pahydroxyethyl cellulose, yog li tshwj xeeb saib yuav tsum tau them rau nws.

Tsis txhob ntxiv qee qhov yooj yim yeeb tshuaj rau qhov sib xyaw ua ntej qib ximTus pahydroxyethyl cellulose hmoov yog soaked nrog dej. Tsa phua tom qab soaking pab yaj.

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

6 Thaum siv cov viscosity qib siab xim qibTus pa, kev caw ntawm niam haus cawv yuav tsum tsis txhob siab dua 2.5-3% (los ntawm qhov hnyav), tsis li tus niam cawv yog qhov nyuaj ua haujlwm.

Yam cuam tshuam rau cov viscosity ntawm looj xim

1.Qhov ntau cov rauv pa npuas nyob hauv cov xim, cov viscosity ntau dua.

2.Yog tus nqi ntawm cov activator thiab dej hauv cov xim mis sib xws?

3 Hauv synthesis ntawm looj, residual catalyst oxide cov ntsiab lus ntawm tus nqi.

4. Cov nqi ntawm lwm cov tog cov khoom siv hauv cov xim pleev xim thiab cov ntau yam piv nrog qibTus pa.)

5.Txawm cov txheej txheem ntawm kev pleev xim, qhov kev txiav txim ntawm cov kauj ruam ntxiv cov thickener yog qhov tsim nyog.

6.Cove mus rau kev ntxhov siab ntau dhau thiab muaj cov av noo ntau thaum lub sij hawm dispersion.

7.Microbial yaig ntawm tuab.
