Mokhoa oa ho sebelisa hydroxyethyl cellulose ka pente ea latex
1. Hydroxyethyl celluloseka motoho joalo ka phenology: hobane hydroxyethyl cellulose ha e qhibilihe habonolo ka har'a lihlapolli tsa lintho tse phelang, litlhare tse ling tsa tlhaho li ka sebelisoa ho hlomella motoho. Metsi a leqhoa le ona ke mokelikeli o mobe, kahoo hangata a sebelisoa motoho o nang le metsi a tlhaho. Selulose ea hydroxyethyl ea mofuta oa congee e ka eketsoa ka kotloloho ka pente ea emulsii. Hydroxyethyl cellulose e tletse ka mokhoa oa motoho. Ha e kenngoa penteng, e potlakela ho qhibiliha ebe e teteaneng. Tsoela pele ho hlohlelletsa ho fihlela hydroxyethyl cellulose e qhalakane ka ho feletseng 'me e qhibiliha. Motoho o tloaelehileng 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, hydroxyethyl cellulose ea hydrolyze 'me e bonahala e phahama. (Ho hlahisoa hore mongobo oa metsi hlabula o phahame haholo hore o ka sebelisoa bakeng sa motoho.)
2. Eketsa cellulose ea hydroxyethyl ka ho toba ho pigment ea ho sila: mokhoa ona o bonolo 'me nako e khutšoanyane. Mekhoa e felletseng ke e latelang:
(1) Eketsa metsi a hloekileng a nepahetseng ho VAT e phahameng e lokela ho khaola sehlohlelletsi (ka kakaretso, li-additives tsa ho etsa filimi le lisebelisoa tsa ho kolobisa lia eketsoa ka nako ena)
(2) Qala ho sisinya ka lebelo le tlase ntle le ho emisa ebe butle-butle eketsa hydroxyethyl cellulose ka ho lekana
(3) Tsoela pele ho sisinya ho fihlela likaroloana tsohle li qhalakanngoa ka ho lekana 'me li kolobisitsoe
(4) Kenya mildew inhibitor 'me u lokise 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 e fetoha pente.
3 the hydroxyethyl selulose le 'mè mokelikeli emetse: mokhoa ona ke pele a hlomelloa le e phahameng ea mahloriso ea' mè mokelikeli, 'me joale eketsa latex pente, molemo oa mokhoa ona ke ho feta tenyetseha, ka ka ho toba eketsa pente qeta lihlahisoa, empa ho polokelo loketseng. Mehato le mekhoa e tšoana le mehato (1) - (4) ho Method 2, ntle le hore moferefere o phahameng oa ho itšeha ha o hlokehe mme ke li-aggers tse ling feela tse nang le matla a lekaneng a ho boloka likhoele tsa hydroxyethyl tse qhalakantsoeng ka mokhoa o ts'oanang le tharollo li sebelisoa. Tsoela pele ho susumetsa ho fihlela e qhibiliha ka ho feletseng ka tharollo e teteaneng. Ela hloko hore: antimildew agent e tlameha ho eketsoa kapele kamoo ho ka khonehang ka har'a joala ba 'mè oa pente.
4 Litaba tse hlokang ho hlokomeloa ha u hlomella joala ba 'mè ba hydroxyethyl cellulose
Kaha hydroxyethyl cellulose ke phofo e entsoeng ka granular, ho bonolo ho sebetsana le ho qhibiliha ka metsing ka mehato e latelang ea ho itšireletsa.
(1) Pele le ka mor'a ho eketsa cellulose ea hydroxyethyl, e tlameha ho lula e tsosoa, ho fihlela tharollo e hlakile ka ho feletseng 'me e hlakile.
(2) Hoa hlokahala ho sefa selulose ea hydroxyethyl ka tanka e tsosang butle. U se ke ua e kenya ka bongata kapa ka ho toba ka tanka e susumetsang.
(3) Ho qhibiliha ha hydroxyethyl cellulose ho hlakile hore ho amana le mocheso oa metsi le pH boleng ba metsi, kahoo ho lokela ho lebisoa tlhokomelo e khethehileng ho eona.
(4) Se ke oa kenya lintho tse ling tsa motheo motsoakong pele phofo ea hydroxyethyl cellulose e kolobisoa ka metsi. Ho phahamisa pH ka mor'a ho inela ho thusa ho qhibiliha.
(5) Kahohle kamoo ho ka khonehang, ho eketsoa pele ha hlobo inhibitor.
(6) Ha u sebelisa viscosity e phahameng ea hydroxyethyl cellulose, motsoako oa joala ba 'mè ha oa lokela ho ba o phahameng ho feta 2.5-3% (ka boima ba' mele), ho seng joalo joala ba 'mè bo thata ho sebetsa.
Lintlha tse amang viscosity ea pente ea latex:
(1) Ka lebaka la ho sisinyeha ho feteletseng le mongobo o feteletseng ha o qhalana.
(2) palo ea li-thickeners tse ling tsa tlhaho ka foromo ea pente le karolo ea chelete e nang lehydroxyethyl cellulose.)
(3) palo ea li-activator tsa holim'a metsi le metsi ka foromo ea pente e lumellana.
(4 ka har'a motsoako oa latex, karolo e setseng ea catalyst oxide ea palo.
Khoholeho ea likokoana-hloko ea thickener.
6 nakong ea ho etsa pente, tatellano ea mehato ea ho eketsa thickener e loketse.
Ha lipululana tsa moea li ntse li le ngata penteng, li na le viscosity e phahameng
