HEC bakeng sa Pente

HEC e khutsufetse bakeng sa hydroxyethyl Cellulose. Hydroxyethyl celluloseHECke 'mala o mosoeu kapa o mosehla o mosehla, o sa latsoeheng, o se nang chefo, o nang le fibrous kapa powdery o lokiselitsoeng ke etherification ea alkaline cellulose le ethylene oxide (kapa chloroethanol). Ke ether e se nang ionic e qhibilihang ka har'a cellulose. Joaloka motho ea se nang ionic, ntle le ho teteka, ho emisoa, ho kopanya, ho phaphamala, ho etsa filimi, ho qhalakanngoa, ho boloka metsi le tšireletso.

Lik'hemik'hale Likaroloana:

1, HEC e ka qhibiliha ka metsing a chesang kapa a batang, mocheso o phahameng kapa ho belisa ha o fokotsehe, e le hore o na le mefuta e mengata ea solubility le viscosity properties, le gel e sa chesang;

2, li-non-ionic tsa eona li ka phela hammoho le mefuta e mengata e mengata ea li-polymers tse qhibilihang ka metsing, li-surfactants, matsoai, ke motsoako o motle oa colloidal o nang le motsoako o phahameng oa tharollo ea electrolyte;

3, matla a ho boloka metsi a phahame habeli ho feta methyl cellulose, e nang le phetoho e ntle ea phallo,

4. HEC e na le bokhoni bo bobe ka ho fetisisa ba ho hasana ha bo bapisoa le methyl cellulose le hydroxypropyl methyl cellulose, empa bokhoni bo matla ka ho fetisisa ba tšireletso ea colloid.

Ka hona, hydroxyethyl cellulose e sebelisoa haholo ts'ebetsong ea peterole, ho roala, ho haha, meriana le lijo, masela, ho etsa pampiri le karabelo ea polymerization le masimo a mang.

E sebelisoa ka electroplating, e ka etsa hore bokaholimo ba plating bo phethehe, bo be khanyang haholoanyane. Habohlokoa le ho feta ke ho sebelisoa ha pente ea borate, silicate le carbonate latex, e ntse e na le viscosity e ntle haholo.

4.Se-membranous

Thepa ea sebopeho sa membrane ea HEC e ka sebelisoa liindastering tse ngata. Mesebetsing ea ho etsa pampiri, e koahetsoeng ka HEC glazing agent, e ka thibela ho kenella ha mafura, 'me e ka sebelisoa ho lokisetsa likarolo tse ling tsa tharollo ea pampiri; HEC e eketsa elasticity ea likhoele nakong ea ho loha 'me kahoo e fokotsa tšenyo ea mochine ho tsona. HEC e sebetsa e le filimi ea nakoana e sireletsang nakong ea boholo le ho daea lesela 'me e ka hlatsuoa ho tloha lesela ka metsi ha tšireletso ea eona e sa hlokahale.

1. Ho boloka metsi

HEC e thusa ho boloka mongobo oa tsamaiso o le boemong bo loketseng. Hobane palo e nyenyane ea HEC ka tharollo ea metsi e ka finyella phello e ntle ea ho boloka metsi, e le hore tsamaiso e fokotse tlhokahalo ea metsi ha ho lokisoa. Ntle le ho boloka metsi le ho khomarela, seretse sa samente se tla fokotsa matla a sona le ho khomarela, 'me letsopa le tla fokotsa polasetiki tlas'a khatello e itseng.

Mokhoa oa ho sebelisa hydroxyethyl cellulose HECka pente ea latex

1. Eketsa ka ho toba ha u sila pigment: mokhoa ona ke o bonolo ka ho fetisisa, 'me nako e sebelisoang e khutšoanyane. Mehato e qaqileng ke e latelang:

(1) Eketsa metsi a hloekisitsoeng a loketseng ka har'a VAT ea moferefere o phahameng oa ho itšeha (ka kakaretso, ethylene glycol, moemeli oa ho kolobisa le mochine oa ho etsa lifilimi li eketsoa ka nako ena)

(2) Qala ho sisinyeha ka lebelo le tlaase 'me butle-butle eketsa hydroxyethyl cellulose

(3) Tsoela pele ho sisinya ho fihlela likaroloana tsohle li kolobile

(4) eketsa hlobo inhibitor, PH regulator, joalo-joalo

(5) Hlohlelletsa ho fihlela cellulose eohle ea hydroxyethyl e qhibiliha ka ho feletseng (viscosity ea tharollo e eketseha haholo) pele o eketsa likarolo tse ling ka foromo, 'me u sila ho fihlela e fetoha pente.

2 a hlomelloa le 'mè mokelikeli emetse: mokhoa ona e pele a hlomelloa le e phahameng ea mahloriso ea' mè mokelikeli, 'me joale eketsa latex pente, molemo oa mokhoa ona ke ho feto-fetoha e khōloanyane, e ka ka ho toba li ekeletsoa ho penta lihlahisoa qeta, empa e lokela ho ba polokelo loketseng. Mehato le mekhoa e tšoana le mehato (1) - (4) ho Method 1, ntle le hore moferefere o phahameng oa ho itšeha ha o hlokehe 'me ke feela agitator e nang le matla a lekaneng a ho boloka likhoele tsa hydroxyethyl ka mokhoa o ts'oanang o qhalakantsoeng ka tharollo e lekaneng. Tsoela pele ho susumetsa ho fihlela e qhibiliha ka ho feletseng ka tharollo e teteaneng. Hlokomela hore inhibitor ea hlobo e tlameha ho eketsoa ho joala ba 'm'a kapele kamoo ho ka khonehang.

3. Papali e kang phenology: Kaha metsoako ea tlhaho ke lihlapolli tse mpe bakeng sa hydroxyethyl cellulose, metsoako ena ea tlhaho e ka kenngoa motoho. Li-solvents tse sebelisoang ka ho fetisisa tse kang ethylene glycol, propylene glycol, le li-filmforming agents (tse kang hexadecanol kapa diethylene glycol butyl acetate), metsi a leqhoa le oona ke mokelikeli o fokolang, kahoo metsi a leqhoa a atisa ho sebelisoa le lino tse phelang ka har'a motoho.

Gruel - joalo ka hydroxyethyl cellulose e ka kenyelletsoa ka ho toba penteng. Hydroxyethyl cellulose e tletse ka mokhoa oa motoho. Ka mor'a ho eketsa lacquer, qhala hang-hang 'me u be le phello e teteaneng. Ka mor'a ho eketsa, tsoela pele ho hlohlelletsa ho fihlela hydroxyethyl cellulose e qhibiliha ka ho feletseng 'me e tšoana. Motoho o tloaelehileng o etsoa ka ho kopanya likarolo tse tšeletseng tsa motsoako oa tlhaho kapa metsi a leqhoa le karolo e le 'ngoe ea hydroxyethyl cellulose. Kamora metsotso e ka bang 5-30, hydroxyethyl cellulose ea hydrolyze 'me e bonahala e phahama. Hlabula, mongobo oa metsi o phahame haholo hore o ka sebelisoa bakeng sa motoho.

4.Litaba tse hlokang ho hlokomeloa ha ho hlomelloa joala ba 'mè ba hydroxyethyl cellulose

Kaha hydroxyethyl cellulose ke phofo e entsoeng ka granular, ho bonolo ho sebetsana le ho qhibiliha ka metsing ka mehato e latelang ea ho itšireletsa.
