Mokhoa oa ho sebelisa hydroxyethyl cellulose ka pente ea latex
1. Hydroxyethyl cellulose e sebelisetsoa ho lokisa 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 lokisa motoho.Metsi a leqhoa le ona ke mokelikeli o fokolang, kahoo metsi a leqhoa a atisa ho sebelisoa le lino tse phelang ho lokisa motoho.Selulose se kang motoho sa hydroxyethyl se ka kenyelletsoa ka ho toba penteng ea latex.Selulose ea hydroxyethyl e ruruhile ka har'a motoho.Ha e kenngoa penteng, e qhibiliha ka potlako 'me e phetha karolo ea ho tiisa.Ka mor'a ho eketsa, ho ntse ho hlokahala hore u tsoele pele ho susumetsa ho fihlela cellulose ea hydroxyethyl e qhalakanngoa ka ho feletseng 'me e qhibiliha.Ka kakaretso, motoho o kopantsoe le likarolo tse tšeletseng tsa motsoako oa motsoako 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.(Ho etsoa tlhahiso ea hore mongobo oa metsi ka kakaretso o phahame haholo hlabula, kahoo ha oa lokela ho sebelisoa bakeng sa motoho.)
2. Kenya hydroxyethyl cellulose ka ho toba ha u sila pigment: Mokhoa ona o bonolo ebile o nka nako e fokolang.Mokhoa o qaqileng ke o latelang:
(1) Eketsa metsi a hloekileng a loketseng ka har'a sekoti sa moferefere o phahameng haholo (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 le ho kolobisoa
(4) Kenya li-additives tsa antifungal 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 e fetoha pente.
3. Lokisetsa hydroxyethyl cellulose ka joala ba 'm'a bakeng sa tšebeliso: 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 habonolo mme o ka kenyelletsoa ka ho toba penteng e phethiloeng, empa e hloka ho bolokoa hantle..Mehato le mekhoa e tšoana le mehato (1) - (4) ka mokhoa oa 2, phapang ke hore ha ho hlokahale hore ho be le moferefere o phahameng, 'me ke li-agitator tse ling feela tse nang le matla a lekaneng ho boloka likhoele tsa hydroxyethyl li hasane ka mokhoa o ts'oanang. tharollo li sebelisoa.Ka.Tsoela pele ho susumetsa kamehla ho fihlela o 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 sebetsana le ho qhibiliha ka metsing hafeela litaba tse latelang li hlokomeloa.
(1) Pele le ka mor'a ho eketsa hydroxyethyl cellulose, e tlameha ho bolokoa e tsosoa ho fihlela tharollo e hlakile ka ho feletseng le e hlakileng.
(2) E tlameha ho sefshoa ka har’a moqomo oa ho tsoaka butle-butle.U se ke ua eketsa ka ho toba cellulose ea hydroxyethyl e entsoeng ka makukuno le libolo ka har'a moqomo oa ho kopanya ka bongata kapa ka ho toba.
(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) Se ke oa kenya lintho tse ling tsa alkaline motsoakong pele phofo ea hydroxyethyl cellulose e kolobisoa ka metsi.Ho phahamisa pH feela ka mor'a ho kolobisa ho tla thusa ho qhibiliha.
(5) Ho fihlela moo ho ka khonehang, eketsa moemeli oa antifungal kapele kamoo ho ka khonehang.
(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) Mongobo o chesa haholo nakong ea ho hasana ka lebaka la ho sisinyeha ho feteletseng.
(2) Tekanyo ea litekanyo tse ling tsa tlhaho le tekanyo ea tekanyo ea hydroxyethyl cellulose ka foromo ea pente.)
(3) Hore na palo ea surfactant le palo ea metsi a foromo ea pente li loketse.
