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, joalo ka starch, marinini a semela (joalo ka Arabic gum), gelatin ea liphoofolo, joalo-joalo. 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.
