1. Eketsa ka ho toba ha u sila pigment: Mokhoa ona ke o bonolo ka ho fetisisa 'me o nka nako e fokolang. Mehato e qaqileng ke e latelang:
(1) Eketsa metsi a hloekisitsoeng a loketseng ho vat ea agitator e phahameng haholo (ka kakaretso, ethylene glycol, metsi a kolobisang le moemeli oa ho etsa filimi kaofela li kenyelelitsoe ka nako ena)
(2) Qala ho sisinyeha ka ho tsoelang pele ka lebelo le tlaase 'me butle-butle eketsa hydroxyethyl cellulose
(3) Tsoela pele ho sisinya ho fihlela likaroloana tsohle li kolobisitsoe
(4) Kenya moemeli oa antifungal, PH adjuster, joalo-joalo.
(5) Hlohlelletsa ho fihlela cellulose eohle ea hydroxyethyl e qhibiliha ka ho feletseng (viscosity ea tharollo e eketseha haholo) pele u eketsa likarolo tse ling ka foromo, 'me u sila ho fihlela e fetoha pente.
2. Lokisetsa joala ba 'm'e bakeng sa tšebeliso: Mokhoa ona ke ho lokisa joala ba 'm'e ka tekanyo e phahameng pele, ebe oe kenya penteng ea latex. Molemo oa mokhoa ona ke hore o na le phetoho e kholoanyane 'me e ka kenyelletsoa ka ho toba penteng e phethiloeng, empa e tlameha ho bolokoa hantle. Mehato le mekhoa e tšoana le mehato ea (1) - (4) ho Method 1, phapang ke hore ha ho hlokahale hore ho be le moferefere o phahameng, 'me ke li-agitator tse ling tse nang le matla a lekaneng ho boloka likhoele tsa hydroxyethyl li hasane ka mokhoa o ts'oanang. tharollo e sebelisoa. Ka. Tsoela pele ho susumetsa kamehla ho fihlela o qhibiliha ka ho feletseng ka tharollo ea viscous. Ho lokela ho hlokomeloa hore moemeli oa antifungal o tlameha ho eketsoa ho 'mè oa joala kapele kamoo ho ka khonehang.
3. Bakeng sa phenology ea motoho: Kaha lihlahisoa tsa tlhaho ke li-solvents tse fokolang tsa hydroxyethyl cellulose, metsoako ena ea tlhaho e ka sebelisoa ho lokisa motoho. Litlhapi tse sebelisoang ka ho fetisisa tse kang ethylene glycol, propylene glycol, le li-film-forming agents (joalo ka hexylene glycol kapa diethylene glycol butyl acetate), metsi a leqhoa le ona ke motsoako o fokolang, kahoo metsi a leqhoa a atisa ho sebelisoa hammoho le metsi a tlhaho. Ho lokisa motoho.
Selulose se kang motoho sa hydroxyethyl se ka eketsoa ka ho toba penteng. Selulose ea hydroxyethyl e ruruhile ka har'a motoho. Ha e kenngoa penteng, hang-hang e qhibiliha ebe e teteaneng. Ka mor'a ho eketsa, e tlameha ho tsosoa ka ho tsoelang pele ho fihlela hydroxyethyl cellulose e qhibiliha ka ho feletseng 'me e tšoana. Ka kakaretso, motoho o kopantsoe le likarolo tse tšeletseng tsa motsoako oa motsoako kapa metsi a leqhoa le karolo e le 'ngoe ea hydroxyethyl cellulose. Kamora metsotso e ka bang 5-30, selulose ea hydroxyethyl e tla be e entsoe ka hydrolyzed mme e ruruhe ho hlakile. Lehlabuleng, mongobo oa metsi ka kakaretso o phahame haholo, 'me ha oa lokela ho sebelisoa bakeng sa motoho.
4. Litaba tse hlokang ho eloa hloko ha ho etsoa joala ba hydroxyethyl cellulose
Kaha hydroxyethyl cellulose ke phofo e entsoeng, ho bonolo ho sebetsana le ho qhibiliha ka metsing hafeela litaba tse latelang li hlokomeloa.
1) Pele le ka mor'a ho eketsa hydroxyethyl cellulose, ho hlokahala hore u lule u susumetsa ho fihlela tharollo e hlakile ka ho feletseng ebile e hlakile.
2) E tlameha ho kenngoa ka har'a moqomo oa ho kopanya butle-butle, 'me u se ke ua eketsa cellulose ea hydroxyethyl e entsoeng ka makukuno kapa libolo ka ho toba ka har'a moqomo oa ho kopanya.
3) Mocheso oa metsi le boleng ba pH metsing li na le kamano e kholo le ho qhibiliha ha hydroxyethyl cellulose, kahoo ho lokela ho lefshoa tlhokomelo e khethehileng ho eona.
4) U se ke ua kenya lintho tse ling tsa alkaline motsoako pele phofo ea hydroxyethyl cellulose e kolobisoa ka metsi. Ho phahamisa pH feela ka mor'a ho kolobisa ho tla thusa ho qhibiliha.
5) Ho fihlela moo ho ka khonehang, eketsa moemeli oa antifungal kapele kamoo ho ka khonehang.
6) Ha u sebelisa high-viscosity hydroxyethyl cellulose, mahloriso a joala ba 'mè ha aa lokela ho ba holimo ho 2.5-3% (ka boima ba' mele), ho seng joalo joala ba 'mè bo tla ba thata ho sebetsana le bona.
