5. Hlohlelletsa ho fihlela cellulose eohle ea hydroxyethyl e qhibiliha ka ho feletseng (viscosity ea tharollo e eketseha haholo) pele u eketsa likarolo tse ling ka foromo, 'me u sila ho fihlela sehlahisoa se felile.
2. Ho hlomelloa ka joala ba 'm'e bakeng sa ho leta
Mokhoa ona ke oa ho qala ka ho lokisetsa joala ba 'mè bo nang le khatello e phahameng, ebe o e eketsa ho pente ea latex.Molemo oa mokhoa ona ke hore o na le phetoho e kholoanyane 'me e ka kenyelletsoa ka ho toba penteng e phethiloeng, empa e lokela ho bolokoa hantle.Mehato e tšoana le mehato ea 1-4 ka mokhoa oa 1, ntle le hore ho tsosoa ho phahameng ha ho hlokahale ho qhibiliha ka ho feletseng ka tharollo ea viscous.
3.E lokiselitsoe motoho bakeng sa tšebeliso
Kaha li-solvents e le lihlapolli tse futsanehileng tsa hydroxyethyl cellulose, metsoako ena ea tlhaho e ka sebelisoa ho lokisa lihlahisoa tse kang motoho.Litlhapi tse sebelisoang ka ho fetesisa ke maro a tlhaho a entsoeng ka pente joalo ka ethylene glycol, propylene glycol le li-former tsa lifilimi (mohlala, ethylene glycol kapa diethylene glycol butyl acetate).Metsi a leqhoa le ona ke mokelikeli o fokolang, kahoo metsi a leqhoa a atisa ho sebelisoa hammoho le lino tse phelang ho lokisa lihlahisoa tse kang motoho.Sehlahisoa se kang motoho, hydroxyethyl cellulose, se ka kenyelletsoa ka ho toba penteng, 'me selulose ea hydroxyethyl e se e le foamed le ho ruruha ke motoho.Ha e kenngoa penteng, e qhibiliha hang-hang 'me e teteaneng.Ka mor'a ho eketsa, ho ntse ho hlokahala hore u tsoele pele ho susumetsa ho fihlela hydroxyethyl cellulose e qhibiliha ka ho feletseng 'me e tšoana.Ka kakaretso, sehlahisoa se kang motoho se kopantsoe le likarolo tse tšeletseng tsa motsoako oa tlhaho kapa metsi a leqhoa le karolo e le 'ngoe ea hydroxyethyl cellulose.Kamora metsotso e ka bang 6-30, selulose ea hydroxyethyl e tla be e entsoe ka hydrolyzed mme e ruruhe ho hlakile.Lehlabuleng, mocheso oa metsi ka kakaretso o phahame haholo, 'me ha oa lokela ho sebelisa lihlahisoa tse tšoanang le motoho.
