Mokhoa oa ho sebelisa hydroxyethyl cellulose ka pente ea latex
1. Hydroxyethyl cellulose e sebelisetsoa ho etsa motoho: Kaha hydroxyethyl cellulose ha e bonolo ho qhibilihisa ka har'a metsoako ea tlhaho, metsoako e meng ea tlhaho e ka sebelisoa ho lokisa motoho. Metsi a leqhoa le 'ona ha a na motsoako o motle, kahoo metsi a leqhoa hangata a sebelisoa hammoho le metsoako ea tlhaho ho lokisa motoho. Hydroxyethyl cellulose e kang porridge e ka eketsoa ka ho toba penteng ea latex. Hydroxyethyl cellulose e kolobisitsoe ka botlalo ka motoho. Ha e eketsoa penteng, e qhibiliha kapele 'me e sebetsa e le setenya. Kamora ho e eketsa, tsoela pele ho hlohlelletsa ho fihlela hydroxyethyl cellulose e qhalakantsoe ka botlalo le ho qhibiliha. Ka kakaretso, motoho 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 tla hydrolyzed 'me e ruruhe ka ho hlaka. (Hopotsa hore mongobo oa metsi a akaretsang o phahame haholo hlabula, kahoo ha oa lokela ho sebelisoa ho hlomella motoho.)
2. Kenya hydroxyethyl cellulose ka kotloloho ha o sila pigment: Mokhoa ona o bonolo mme o nka nako e kgutshwane. Mokhoa o qaqileng ke o latelang:
(1) Kenya metsi a hloekisitsoeng a lekaneng ka baketeng e kholo ea motswako o nang le sesepa se seholo (ka kakaretso, lintho tse thusang ho etsa filimi le lintho tse kolobisang lia eketsoa nakong ena)
(2) Qala ho hlohlelletsa ka ho tsoelang pele ka lebelo le tlase 'me butle-butle le ka ho lekana eketsa hydroxyethyl cellulose
(3) Tswela pele ho hlohlelletsa ho fihlela dikarolwana tsohle di hasantswe ka ho lekana mme di kolobiswa
(4) Kenya di-additives tse thibelang hlobo ho lokisa 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 pente e bopilwe.
3. Lokisa hydroxyethyl cellulose ka joala ba 'm'e bakeng sa tšebeliso ea morao: Mokhoa ona ke ho lokisa joala ba 'm'e ka mahloriso a phahameng pele, ebe o bo eketsa penteng ea latex. Molemo oa mokhoa ona ke hore o tenyetseha haholoanyane 'me o ka eketsoa ka ho toba penteng e phethiloeng, empa o tlameha ho bolokoa hantle. . Mehato le mokhoa li tšoana le mehato (1)-(4) mokhoeng oa 2, phapang ke hore ha ho hlokahale agitator e matla, 'me ke li-agitator tse ling feela tse nang le matla a lekaneng ho boloka faeba ea hydroxyethyl e hasane ka ho lekana ka har'a tharollo ke Can. Tsoela pele ho hlohlelletsa khafetsa ho fihlela e qhibiliha ka botlalo hore e be tharollo e nang le viscous. Ho lokela ho hlokomeloa hore moemeli oa antifungal o tlameha ho eketsoa ho joala ba 'm'e oa pente kapele kamoo ho ka khonehang.
4 Lintho tse hlokang tlhokomelo ha ho lokisoa joala ba hydroxyethyl cellulose
Kaha hydroxyethyl cellulose ke phofo e sebetsitsoeng, ho bonolo ho e sebetsana le ho e qhibilihisa ka metsing ha feela lintho tse latelang li eloa hloko.
(1) Pele le ka mora ho eketsa hydroxyethyl cellulose, e lokela ho hlohlelletsoa khafetsa ho fihlela tharollo e bonaletsa ka botlalo ebile e hlakile.
(2) E lokela ho sefshoa butle-butle ka tankeng ea ho kopanya, 'me u se ke ua eketsa ka ho toba palo e kholo ea hydroxyethyl cellulose e entseng li-klips kapa libolo ka tankeng ea ho kopanya.
(3) Mocheso oa metsi le boleng ba pH metsing li na le kamano ea bohlokoa le ho qhibiliha ha hydroxyethyl cellulose, kahoo tlhokomelo e khethehileng e lokela ho lefshoa.
(4) O se ke wa eketsa dintho tse ding tsa alkaline motswakong pele phofo ya hydroxyethyl cellulose e kolobiswa ka metsi. Ho phahamisa pH kamora ho kolobisa ho thusa ho qhalana.
(5) Ka hohle kamoo ho ka khonehang, eketsa sebolaya-fungus esale pele.
(6) Ha o sebedisa 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 tla ba thata ho bo sebetsana.
Mabaka a amang viscosity ea pente ea latex:
(1) Ka lebaka la ho hlohlelletsa ho feteletseng, mongobo o futhumala haholo nakong ea ho hasana.
(2) Palo ea lintho tse ling tse tenyang tsa tlhaho tse entsoeng ka pente le karolelano ea bongata ba hydroxyethyl cellulose.
(3) Hore na bongata ba surfactant le bongata ba metsi a sebelisitsoeng foromong ea pente li loketse.
(4) Ha ho kopanngoa latex, bongata ba oxide e kang catalyst e setseng bo khethoa.
(5) Ho senyeha ha sethibela-mafu ke dikokwana-hloko.
(6) Mokgweng wa ho etsa pente, na tatellano ya mehato ya ho eketsa setenya e loketse.
7 Ha dipululana tsa moya di ntse di le ngata penteng, viscosity e ba e phahameng
