hydroxyethyl cellulose ke eng?
Hydroxyethyl cellulose (HEC), e bosoeu kapa bo mosehla bo bobebe, bo se nang monko, bo se nang chefo kapa bo tiileng, bo lokisitsoeng ke etherification ea alkaline cellulose le ethylene oxide (kapa chlorohydrin), e leng ea mofuta oa Nonionic soluble cellulose ethers.Hobane HEC e na le thepa e ntle ea ho tiisa, ho emisa, ho qhalakanya, emulsifying, ho tlamahane, ho etsa filimi, ho sireletsa mongobo le ho fana ka li-colloid tse sireletsang, e 'nile ea sebelisoa haholo ho hlahloba oli, ho roala, ho haha, meriana le lijo, masela, ho etsa pampiri le li-polymers.Polymerization le likarolo tse ling.
Ho etsahalang ha hydroxyethyl cellulose e kopana le metsipenta?
Joalo ka sehlahisoa se seng sa ionic, hydroxyethyl cellulose e na le lintho tse latelang ho kenyelletsa ho tenya, ho emisa, ho tlama, ho phaphamala, ho etsa filimi, ho qhalakanya, ho boloka metsi le ho fana ka li-colloid tse sireletsang:
HEC e qhibiliha ka metsing a chesang kapa a batang, 'me ha e chese ka mocheso o phahameng kapa ho belisoa, ho etsa hore e be le mefuta e mengata ea ho qhibiliha le litšoaneleho tsa viscosity, hammoho le gelling e sa chesang;
Bokhoni ba ho boloka metsi bo habeli ho feta ba methyl cellulose, 'me bo na le taolo e ntle ea phallo;
Ha ho bapisoa le methyl cellulose e tsejoang le hydroxypropyl methyl cellulose, bokhoni ba ho qhalakanngoa ba HEC ke bona bo bobe ka ho fetisisa, empa matla a tšireletso a colloid ke a matla ka ho fetisisa;
Ha e na ionic 'me e ka phela hammoho le mefuta e mengata e mengata ea li-polymers tse qhibilihang metsing, li-surfactants le matsoai.Ke colloidal thickener e babatsehang bakeng sa tharollo ea electrolyte e phahameng haholo.
Mokhoa oa ho sebelisa hydroxyethyl cellulose?Joang ho e eketsa?
Eketsa ka ho toba nakong ea tlhahiso - mokhoa ona o bonolo ka ho fetisisa 'me o nka nako e fokolang.
Eketsa metsi a hloekileng ka har'a vat e nang le blender e phahameng ea ho kuta.Qala ho sisinya o sa kgaotse ka lebelo le tlase mme butle o sefa hydroxyethyl cellulose ka ho lekana ka hara tharollo.Tsoela pele ho hlohlelletsa ho fihlela likaroloana tsohle li kolobisitsoe.Ebe u eketsa li-preservatives le li-additives tse fapaneng.Tse kang li-pigments, lithuso tsa ho qhala, metsi a ammonia, joalo-joalo Hlohlelletsa ho fihlela cellulose eohle ea hydroxyethyl e qhibiliha ka ho feletseng (viscosity ea tharollo e eketseha haholo) pele o eketsa likarolo tse ling ka foromo ho phethahatsa karabelo.
Ho hlomelloa ka joala ba 'm'e.
Ke ho lokisetsa joala ba 'm'e ka motsoako o phahameng pele, ebe o e eketsa sehlahisoa.Molemo oa mokhoa ona ke hore o na le phetoho e kholoanyane 'me e ka kenyelletsoa ka ho toba sehlahisoa se phethiloeng, empa se tlameha ho bolokoa hantle.Mehato ea mokhoa ona e tšoana le mehato e mengata ea Method 1;phapang ke hore ha ho hlokahale hore ho be le agitator e phahameng, 'me ke li-agitator tse ling feela tse nang le matla a lekaneng a ho boloka cellulose ea hydroxyethyl ka mokhoa o ts'oanang e qhalakantsoeng ka tharollo e ka sebelisoa,' me e tsoele pele ho Hlohlelletsa ho fihlela e qhibiliha ka ho feletseng ka tharollo ea viscous.Leha ho le joalo, ho lokela ho hlokomeloa hore moriana oa antifungal o tlameha ho eketsoa ho joala ba 'mè kapele kamoo ho ka khonehang.
Kaha selulose ea hydroxyethyl e entsoeng ka holim'a metsi ke phofo kapa fibrous solid, Shandong Heda o u hopotsa hore u ele hloko lintlha tse latelang ha u lokisetsa joala ba hydroxyethyl cellulose:
(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 hloekisoa butle-butle ka har'a moqomo oa ho kopanya, 'me u se ke ua kopanya ka ho toba hydroxyethyl cellulose le hydroxyethyl cellulose ka har'a moqomo oa ho kopanya ka bongata kapa ka mokhoa oa li-lumps le libolo.
(3) Mocheso oa metsi le pH ea metsi li na le kamano e totobetseng le ho qhibiliha ha hydroxyethyl cellulose, kahoo tlhokomelo e khethehileng e lokela ho lefshoa ho eona.
(4) Le ka mohla u se ke ua 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 esale pele.
(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 thata ho bo tšoara.
