Tšebeliso ea hydroxyethyl cellulose penteng ea latex ke e latelang: 1. Kenya ka ho toba ha u sila pigment: mokhoa ona o bonolo, 'me nako e sebelisoang e khutšoanyane. Mehato e qaqileng ke e latelang: (1) eketsa metsi a hloekisitsoeng hantle (ka tloaelo, ethylene glycol, mokelikeli o kolobisang le mokelikeli o etsang filimi lia eketsoa ka nako ena)(2) qala ho hlohlelletsa ka lebelo le tlase khafetsa 'me butle-butle eketsa hydroxyethyl cellulose (3) tsoela pele ho hlohlelletsa ho fihlela likaroloana tsohle li le metsi (4) eketsa mokelikeli oa hlobo; PH regulator, jj. (5) hlohlelletsa ho fihlela hydroxyethyl cellulose eohle e qhibiliha ka botlalo (tharollo ea viscosity e eketseha) pele u eketsa likarolo tse ling tsa foromo, u sila ho fihlela pente.
2. E hlomeletsoe ka joala ba 'm'e bo emetseng ho sebelisoa: mokhoa ona o qala ka ho hlomelloa ka bongata bo phahameng ba joala ba 'm'e, ebe o eketsoa penteng ea latex, mokhoa ona o na le monyetla oa ho tenyetseha haholoanyane, o ka eketsoa ka ho toba lihlahisoa tsa pente, empa o lokela ho bolokoa hantle. Mehato le mekhoa li tšoana le mehato (1)-(4) mokhoeng oa 1, ntle le hore ha ho hlokahale agitator e phahameng ea ho kuta, 'me ke agitator feela e nang le matla a lekaneng a ho boloka likhoele tsa hydroxyethyl li hasane ka ho lekana ka har'a tharollo e hlokahalang. Tsoela pele ho hlohlelletsa ho fihlela e qhibiliha ka ho feletseng ka tharollo e nang le viscous. Hlokomela hore: inhibitor ea hlobo e tlameha ho eketsoa ho joala ba 'm'e kapele kamoo ho ka khonehang. 3. Congee e nang le phenology: kaha li-solvents tsa organic bakeng sa hydroxyethyl cellulose ke solvent e mpe, kahoo li-solvents tsena tsa organic li ka sebelisoa ho lokisa congee. Metswako e sebediswang hangata ya tlhaho jwalo ka ethylene glycol, propylene glycol, le dihlahiswa tse etsang filimi (jwalo ka hexanediol kapa diethylene glycol butyl acetate), metsi a leqhoa le ona ha a na thapo e lekaneng, kahoo hangata a sebediswa le diedi tsa tlhaho ho lokisa motoho. Hydroxyethyl cellulose e kang porridge e ka eketswa ka ho toba penteng. Hydroxyethyl cellulose e tsholotswe ka botlalo ka motoho. Ha lacquer e eketswa, e a qhibiliha hanghang mme e a teteana. Kamora ho e eketsa, e tlameha ho hlohlelletswa ka ho tswela pele ho fihlela hydroxyethyl cellulose e qhibilihile ka botlalo mme e tshwana. Ka kakaretso motoho o na le dikarolo tse tsheletseng tsa thapo ya tlhaho kapa metsi a leqhoa le karolo ya motswako wa hydroxyethyl cellulose, metsotso e ka bang 5-30 hamorao, hydroxyethyl cellulose e tla hydrolyzed mme e ruruhe. Lehlabula ha mongobo o akaretsang wa metsi o le hodimo haholo, o sa lokelang ho kenngwa motoho.
3. Ntlha ea bone. Hlokomela ha u lokisa joala ba 'mè ba hydroxyethyl cellulose kaha hydroxyethyl cellulose ke karoloana e phofshoana e phekotsoeng, ho bonolo ho e sebelisa le ho e qhala ka metsing ka ho ela hloko tse latelang. 1 pele le ka mor'a ho eketsa hydroxyethyl cellulose, motsoako o lokela ho hlohlelletsoa khafetsa ho fihlela tharollo e bonaletsa ka botlalo ebile e hlakile. 2 e tlameha ho sefshoa ka har'a teramo e kopanyang, u se ke ua ba le palo e kholo ea li-cups kapa libolo tsa hydroxyethyl cellulose e ekelitsoe ka ho toba ka har'a teramo e kopanyang. 3 ho qhibiliha ha hydroxyethyl cellulose ho amana le mocheso oa metsi le boleng ba pH ka metsing, e leng se lokelang ho eloa hloko ka ho khetheha. 4 u se ke ua eketsa lintho tse ling tsa motheo motsoakong pele phofo ea hydroxyethyl cellulose e tlala metsi. Ho eketsa pH ka mor'a ho e qoelisa ho thusa ho qhala. 5 kamoo ho ka khonehang, ho eketsa moemeli oa anti-mildew esale pele. 6 ha u sebelisa hydroxyethyl cellulose e nang le viscosity e phahameng, mahloriso a joala ba 'mè a ke ke a ba holimo ho feta 2.5-3% (gravimeter), ho seng joalo joala ba 'mè bo thata ho bo sebelisa. Mabaka a amang viscosity ea pente ea latex:
1 Ha diteng tsa dipululana tsa moya penteng di le ngata, viscosity e ba hodimo. 2 bongata ba activator ya bokahodimo le metsi a sebediswang foromong ya pente bo loketse. 3 tlhahisong ya latex, bongata ba di-catalyst tse setseng le di-oxide tse ding. 4 bongata ba di-thickeners tse ding tsa tlhaho foromong ya pente le karolelano le hydroxyethyl cellulose. 5 tshebetsong ya pente, ho eketsa tatellano ya mehato ya thickener ho loketse. 6 ka lebaka la ho tsikinyeha ho feteletseng e le hore ha mongobo o hasantsweng o fetele. 7 ho bola ha dikokwana-hloko tsa Thickener.
