Bekeng e fetileng, re buile ka lisebelisoa tse ling tse entsoeng ka oli le phofo ka thepa ea matrix ea litlolo. Kajeno, re tla tsoela pele ho hlalosa lisebelisoa tse setseng tsa matrix: lisebelisoa tsa marenene le lisebelisoa tsa solvent.
Lisebelisoa tse tala tsa Colloidal - bahlokomeli ba viscosity le botsitso
Lisebelisoa tse tala tsa Glial ke metsoako ea polymer e qhibilihang ka metsing. Bongata ba lintho tsena li ka atoloha ho ba colloid ka metsing ho etsa phofo e tiileng le sebopeho. Li ka boela tsa sebelisoa e le li-emulsifiers ho tsitsisa li-emulsions kapa li-suspensions. Ho phaella moo, ba ka boela ba etsa lifilimi le ho thibela gel. Lisebelisoa tse tala tsa glial tse sebelisoang ho litlolo li arotsoe haholo ka mekhahlelo e meraro: ea tlhaho le ea maiketsetso, le ea semi synthetic.
Metsoako ea tlhaho ea polymer e qhibilihang ka metsing: hangata e tsoang ho limela kapa liphoofolong, tse kang starch, gum ea semela (e kang Arabic gum), gelatin ea liphoofolo, joalo-joalo Boleng ba lisebelisoa tsena tse tala tsa marenene tse tsoang ka tlhaho li ka 'na tsa se ke tsa tsitsa ka lebaka la ho fetoha ha boemo ba leholimo le tikoloho,' me ho na le kotsi ea ho silafatsoa ke libaktheria kapa hlobo.
Metsoako ea polymer e qhibilihang ka metsing, e kenyelletsang joala ea polyvinyl, polyvinylpyrrolidone, polyacrylic acid, joalo-joalo, e na le thepa e tsitsitseng, ho halefa ha letlalo le tlase, le litheko tse tlase, ka hona ho nkela metsoako ea tlhaho e qhibilihang ka metsing e le mohloli o ka sehloohong oa lisebelisoa tsa colloidal. Hangata e sebelisoa e le sekhomaretsi, se teteaneng, se etsang filimi, le emulsifying stabilizer ho litlolo.
Semi synthetic water-soluble polymer compounds: Tse tloaelehileng haholo li kenyelletsa methyl cellulose, ethyl cellulose, carboxymethyl cellulose sodium hydroxyethyl cellulose, guar gum le lihlahisoa tsa eona, joalo-joalo.
Lisebelisoa tse tala tse qhibilihisang - senotlolo sa ho qhibiliha le botsitso
Lisebelisoa tse tala ke likarolo tsa bohlokoa mecheng e mengata ea metsi, peista le ho peista e thehiloeng letlalong. Ha li kopantsoe le lisebelisoa tse ling ka foromo, li boloka thepa e itseng ea 'mele ea sehlahisoa. Lisebelisoa tse tala tse sebelisoang hangata ka litlolo li kenyelletsa metsi, ethanol, isopropanol, n-butanol, ethyl acetate, joalo-joalo Metsi ke a mangata a sebelisoang lihlahisoa tsa letlalo.
