Mokhoa oa ho sebelisa hydroxyethyl cellulose ka pente ea latex
1. Hydroxyethyl celluloseka motoho o kang phenology: hobane hydroxyethyl cellulose ha e qhibilihe habonolo ka har'a metsoako ea tlhaho, metsoako e meng ea tlhaho e ka sebelisoa ho hlomella motoho. Metsi a leqhoa le ona ke motsoako o mobe, kahoo hangata a sebelisoa ka motoho o nang le metsoako ea tlhaho. Hydroxyethyl cellulose ea mofuta oa congee e ka eketsoa ka ho toba ka pente ea emulsii. Hydroxyethyl cellulose e tšetsoe ka mokhoa oa motoho. Ha e eketsoa penteng, e qhibiliha kapele 'me ea teteana. Tsoela pele ho hlohlelletsa ho fihlela hydroxyethyl cellulose e qhalakantsoe ka botlalo 'me e qhibiliha. Motoho o tloaelehileng o etsoa ka ho kopanya likarolo tse tšeletseng tsa organic solvent kapa metsi a leqhoa le karolo e le 'ngoe ea hydroxyethyl cellulose. Kamora metsotso e ka bang 5-30, hydroxyethyl cellulose e hydrolyze 'me e phahama ka ho hlaka. (Ho boleloa hore mongobo oa metsi lehlabula o phahame haholo hore o ka sebelisoa bakeng sa motoho.)
2. Kenya hydroxyethyl cellulose ka ho toba pigment e silang: mokhoa ona o bonolo mme nako e kgutshwane. Mekhoa e qaqileng ke ena:
(1) Eketsa metsi a hloekileng a loketseng ho VAT e phahameng e lokela ho khaola agitator (ka kakaretso, li-additives tse etsang filimi le lintho tse nosetsang lia eketsoa nakong ena)
(2) Qala ho hlohlelletsa ka lebelo le tlase ntle le ho emisa ebe o eketsa butle-butle hydroxyethyl cellulose ka ho lekana
(3) Tswela pele ho hlohlelletsa ho fihlela dikarolwana tsohle di hasantswe ka ho lekana mme di kolobiswa
(4) Kenya sethibela-mofuta oa hlobo 'me u fetole boleng ba PH
(5) Hlohlelletsa ho fihlela hydroxyethyl cellulose eohle e qhibilihile ka botlalo (ho teteana ha tharollo ho eketseha haholo), ebe o eketsa dikarolo tse ding foromong, mme o sila ho fihlela e fetoha pente.
3 hydroxyethyl cellulose e nang le mokelikeli oa 'm'e o emetseng: mokhoa ona o qala ka ho hlomelloa ka bongata bo phahameng ba mokelikeli oa 'm'e, ebe o eketsa pente ea latex, molemo oa mokhoa ona o tenyetseha haholoanyane, o ka eketsa lihlahisoa tse felileng tsa pente ka kotloloho, empa polokelong e loketseng. Mehato le mekhoa li tšoana le mehato (1) - (4) ho Mokhoa oa 2, ntle le hore ha ho hlokahale agitator e phahameng ea ho seha 'me ke li-aggregator tse ling feela tse nang le matla a lekaneng ho boloka likhoele tsa hydroxyethyl li hasane ka ho lekana ka har'a tharollo tse sebelisoang. Tsoela pele ho hlohlelletsa ho fihlela e qhibiliha ka botlalo hore e be tharollo e teteaneng. Hlokomela hore: setlhare sa antimildew se tlameha ho eketsoa kapele kamoo ho ka khonehang penteng ea 'm'e joala.
4 Litaba tse hlokang tlhokomelo ha ho hlomelloa joala ba hydroxyethyl cellulose
Kaha hydroxyethyl cellulose ke phofo e nang le granular e phekotsoeng, ho bonolo ho e sebetsana le ho e qhibilihisa ka metsing ka mehato e latelang ea tlhokomelo.
(1) Pele le ka mora ho eketsa hydroxyethyl cellulose, e lokela ho tswela pele ho hlohlelletsa, ho fihlela tharollo e bonaletsa ka botlalo ebile e hlakile.
(2) Ho hlokahala ho sefa hydroxyethyl cellulose ka tankeng e hlohlelletsang butle. U se ke ua e eketsa ka bongata kapa ka ho toba ka tankeng e hlohlelletsang.
(3) Ho qhibiliha ha hydroxyethyl cellulose ho hlakile hore ho amana le mocheso oa metsi le boleng ba pH ba metsi, kahoo tlhokomelo e khethehileng e lokela ho lefshoa ho eona.
(4) O se ke wa eketsa dintho tse ding tsa motheo motswakong pele phofo ya hydroxyethyl cellulose e kolobiswa ka metsi. Ho phahamisa pH kamora ho e qoela ho thusa ho qhibilihisa.
(5) Ka hohle kamoo ho ka khonehang, ho eketsoa ha thibelo ea hlobo kapele.
(6) Ha ho sebediswa hydroxyethyl cellulose e nang le viscosity e phahameng, bongata ba jwala ba mme ha boa lokela ho feta 2.5-3% (ka boima), ho seng jwalo jwala ba mme bo thata ho bo sebedisa.
Mabaka a amang viscosity ea pente ea latex:
(1) Ka lebaka la ho hlohlelletsa ho feteletseng le mongobo o feteletseng ha ho hasana.
(2) bongata ba lintho tse ling tse teteaneng tsa tlhaho foromong ea pente le karolo ea bongata bo nang lehydroxyethyl cellulose.)
(3) bongata ba activator ea bokaholimo le metsi ka har'a foromo ea pente bo tsitsitse.
(4 tlhahisong ea latex, palo ea oxide ea catalyst e setseng.
Ho senyeha ha sekotwana sa microbial.
6 ts'ebetsong ea ho etsa pente, tatellano ea mehato ea ho eketsa setenya e loketse.
Ha dipululana tsa moya tse setseng penteng di ntse di eketseha, viscosity e ba hodimo.
