Mokhoa oa ho sebelisa hydroxyethyl cellulose ka pente ea latex
1. Hydroxyethyl cellulose e sebelisetsoa ho etsa motoho: Kaha hydroxyethyl cellulose ha ho bonolo ho qhibiliha ka har'a metsoako ea lintho tse phelang, metsoako e meng ea tlhaho e ka sebelisoa ho lokisetsa motoho. Metsi a leqhoa le ona ha a na solvent, kahoo metsi a leqhoa a atisa ho sebelisoa hammoho le lino tse phelang ho lokisa motoho. Selulose e kang porridge e kang hydroxyethyl e ka eketsoa ka kotloloho penteng ea latex. Hydroxyethyl cellulose e kolobisitsoe ka ho feletseng ka motoho. Ha e kenngoa penteng, e qhibiliha ka potlako 'me e sebetsa e le motenya. Ka mor'a ho eketsa, tsoela pele ho hlohlelletsa ho fihlela hydroxyethyl cellulose e qhalakanngoa ka ho feletseng 'me e qhibiliha. Ka kakaretso, motoho 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, selulose ea hydroxyethyl e tla be e entsoe ka hydrolyzed mme e ruruhe ho hlakile. (Hopotsa hore mongobo oa metsi ka kakaretso o phahame haholo hlabula, ka hona ha oa lokela ho sebelisoa ho hlomella motoho.)
2. Kenya hydroxyethyl cellulose ka ho toba ha u sila pigment: Mokhoa ona o bonolo ebile o nka nako e khutšoanyane. Mokhoa o qaqileng ke o latelang:
(1) Kenya palo e loketseng ea metsi a hloekisitsoeng ka nkhong e kholo ea motsoako o phahameng oa ho kuta (ka kakaretso, lithuso tsa ho etsa lifilimi le lisebelisoa tsa ho kolobisa lia eketsoa ka nako ena)
(2) Qala ho sisinyeha ka ho tsoelang pele ka lebelo le tlaase 'me butle-butle le ka ho lekana eketsa hydroxyethyl cellulose
(3) Tsoela pele ho sisinya ho fihlela likaroloana tsohle li qhalakanngoa ka ho lekana 'me li kolobisitsoe
(4) Kenya li-additives tse thibelang hlobo ho fetola boleng ba PH
(5) Hlohlelletsa ho fihlela cellulose eohle ea hydroxyethyl e qhibiliha ka ho feletseng (viscosity ea tharollo e eketseha haholo), ebe u eketsa likarolo tse ling ka foromo, 'me u sila ho fihlela pente e thehoa.
3. Lokisetsa hydroxyethyl cellulose ka joala ba 'm'a bakeng sa tšebeliso ea morao-rao: Mokhoa ona ke ho lokisa joala ba 'm'e ka tekanyo e phahameng pele, ebe o e kenya penteng ea latex. Molemo oa mokhoa ona ke hore o fetoha le maemo 'me o ka kenyelletsoa ka ho toba penteng e phethiloeng, empa e tlameha ho bolokoa hantle. . Mehato le mokhoa li tšoana le mehato (1) - (4) ka mokhoa oa 2, phapang ke hore ha ho na agitator e phahameng ea ho kuta e hlokahalang, 'me ke li-agitator tse ling feela tse nang le matla a lekaneng ho boloka fiber ea hydroxyethyl e qhalakantsoeng ka ho lekana ka tharollo ke Can. . Tsoela pele ho hlohlelletsa ho fihlela e qhibiliha ka ho feletseng ka tharollo ea viscous. Ho lokela ho hlokomeloa hore moemeli oa antifungal o tlameha ho eketsoa ho 'mè oa pente joala kapele kamoo ho ka khonehang.
4 Litaba tse hlokang ho hlokomeloa ha ho etsoa joala ba hydroxyethyl cellulose
Kaha hydroxyethyl cellulose ke phofo e entsoeng, ho bonolo ho e tšoara le ho e qhaqha ka metsing hafeela lintho tse latelang li lebisoa tlhokomelo ho tsona.
(1) Pele le ka mor'a ho eketsa hydroxyethyl cellulose, e tlameha ho tsosoa ka ho tsoelang pele ho fihlela tharollo e hlakile ka ho feletseng le e hlakileng.
(2) E tlameha ho sefshoa butle-butle ka har'a tanka e tsoakang, 'me u se ke ua eketsa ka ho toba palo e kholo ea hydroxyethyl cellulose e entseng makukuno kapa libolo ka tanka e kopanyang.
(3) Thempereichara ea metsi le boleng ba pH metsing li na le kamano ea bohlokoa le ho qhalana ha hydroxyethyl cellulose, kahoo ho lokela ho lefshoa tlhokomelo e khethehileng.
(4) Se ke oa kenya lintho tse ling tsa alkaline motsoakong pele phofo ea hydroxyethyl cellulose e kolobisoa ka metsi. Ho phahamisa pH ka mor'a ho ntša metsi ho thusa ho qhibiliha.
(5) Ho fihlela moo ho ka khonehang, eketsa anti-fungal agent pele ho nako.
(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.
Lintlha tse amang viscosity ea pente ea latex:
(1) Ka lebaka la ho sisinyeha ho feteletseng, mongobo o chesa haholo nakong ea ho hasana.
(2) Palo ea litekanyo tse ling tsa tlhaho ha ho etsoa pente le karo-karolelano ea chelete ho hydroxyethyl cellulose.
(3) Hore na palo ea surfactant le bongata ba metsi a sebelisitsoeng foromong ea pente li loketse.
(4) Ha o kopanya latex, palo ea lintho tse nang le oxide e kang catalyst e setseng.
(5) Ho bola ha motenya ke likokoana-hloko.
(6) Ts'ebetsong ea ho etsa pente, hore na tatellano ea mehato ea ho eketsa thickener e loketse.
7 Ha lipululana tsa moea li ntse li le ngata penteng, li-viscosity li phahame
