Ikhwalithi ephezulu ye-Hydroxyethyl cellulose yomkhakha wokumboza

Incazelo emfushane:

1. Ukuvela kwe-HEC Hydroxyethyl cellulose akunambitheki, akunaphunga futhi akunabuthi kumhlophe kuyimpuphu ewumbumbulu ephuzi kancane.

2. Yi-ether ye-nonionic cellulose. I-HEC inemisebenzi yokukhulisa, ukwakha, ukufaka emulsifying, ukusabalalisa, ukuzinzisa nokugcina amanzi. Ihlakazeka kalula emanzini abandayo futhi ashisayo ukuhlinzeka ngezixazululo eziningi ze-viscosity, ifomu lefilimu futhi inikeze umphumela wokuvikela i-colloid.

3. I-HEC ivimba i-electrolyte ephezulu yokuhlushwa. Amandla ayo okugcina amanzi aphindwe kabili kune-MC. Inomthethonqubo omuhle wokugeleza.

Isingeniso Esifushane:

1. Ukuvela kwe-HEC Hydroxyethyl cellulose akunambitheki, akunaphunga futhi akunabuthi kumhlophe kuyimpuphu ewumbumbulu ephuzi kancane.

2. Yi-ether ye-nonionic cellulose. I-HEC inemisebenzi yokukhulisa, ukwakha, ukufaka emulsifying, ukusabalalisa, ukuzinzisa nokugcina amanzi. Ihlakazeka kalula emanzini abandayo futhi ashisayo ukuhlinzeka ngezixazululo eziningi ze-viscosity, ifomu lefilimu futhi inikeze umphumela wokuvikela i-colloid.

3. I-HEC ivimba i-electrolyte ephezulu yokuhlushwa. Amandla ayo okugcina amanzi aphindwe kabili kune-MC. Inomthethonqubo omuhle wokugeleza.

4. Upende omuhle we-emulsion udinga i-rheology ekhethekile yokupenda ukuqinisekisa ukulingana okuhle nokuqeda imikhondo yebhulashi ebusweni befilimu eyomile yomdwebo. I-rheology ihlobene nosayizi nokusatshalaliswa kwama-granules we-emulsion, kepha usayizi nokusatshalaliswa kunomthelela ohlelweni lokuzinza nobuchwepheshe be-polymerization obamukelwe ku-polymerization.

5. I-polymerization ebangelwe ukusebenzisa i-HEC njengama-colloids avikelayo izokhiqiza ikhwalithi efanayo ye-emulsion, ngaphandle komehluko emaqoqweni ahlukene we-emulsion: okwamanje ubukhulu be-emulsion granule bungalawulwa ngaphakathi komkhawulo omncane futhi ama-granules azosebenza njengezinto ezibalulekile ze-emulsion polymerization.

6. I-emulsion polymerizations evame ukusebenzisa i-HEC njenge-colloid evikelayo

Vinyl acetate nezinye monomers copolymerizing ezifana acrylic tesin, butadiene resin para-butadiene resin ethylene njll

7. I-methyl acrylic resin namanye ama-monomers wokukopisha njenge-acrylate, butadiene njll. I-Styrene-acrylate copolymer, ikhophi ye-styrene-butadlene mer, i-vinyl chloride-acrylate copplymer, i-acrylonitrile- butadiene copolmer.

Hydroxyethyl cellulose for enamathela umkhakha-1

Ukucaciswa:

Igama I-cellulose ye-Hydroxyethyl
CAS NO. 9004-62-0
Thayipha I-HE30MC, i-HE50MC, i-HE100MC ...
Ukubukeka I-powder egeleza ngokukhululeka emhlophe
Ubuningi besisindo 250-550 (kg / cm 3)
Usayizi wezinhlayiyana (odlula u-0.212mm)% 92
Okuqukethwe komswakama 5%
PH inani 5.0-9.0
Izinsalela (Ash) 4%
I-viscosity (isixazululo esingu-2%) 300--10 00000S (mPa.s, NDJ-1)
Iphakheji 25 (kg / isikhwama)

Isicelo:

1. I-HEC yi-thickener esetshenziswa kakhulu kupende weLatex.

2. Ngaphezu kokuqina ngopende weLatex, unomsebenzi wokuqhafaza ukusabalalisa, ukuzinzisa nokugcina amanzi Izakhiwo zawo zingumphumela obalulekile wokuqina, nokuqina kwesicathulo, ukwakha ifilimu nokuqina kokugcina.

3. I-HEC yi-nonionic cellulose ether engasetshenziswa ezinhlotsheni eziningi ze-PH. It has ukuhambisana okuhle nezinye izinto, ezifana sombala, izinsiza, fillers kanye nosawoti, ukusebenza okuhle futhi yokululama. Akulula ukuconsa ukuxegiselwa nokusakazeka. 

Ukusebenza Main:

➢ Ukusabalalisa okulula nokuqedwa emanzini apholile, asikho isigaxa

➢ Ukumelana kwe-spatter okuvelele

➢ Ukwamukelwa okuhle kombala nentuthuko

➢ Ukuzinza okuhle

➢ Kuhle ukuzinza kwe-bio. akukho ukulahleka kwe-viscosity
