Kumapende asekelwe emanzini, ama-emulsions, ama-thickeners, ama-dispersants, ama-solvents, ama-level ejenti anganciphisa ukungezwani okungaphezulu kopende, futhi lapho lokhu kunciphisa kunganele, ungakhetha i-ejenti yokumanzisa engaphansi.

Sicela uqaphele ukuthi ukukhetha okuhle kwe-ejenti yokumanzisa ye-substrate kungathuthukisa indawo yokulinganisa kapende ophuma emanzini, ngakho-ke ama-ejenti amaningi okumanzisa ama-substrate angama-leveling.

Izinhlobo zama-ejenti wokumanzisa we-substrate yilezi: ama-anionic surfactants, ama-nonionic surfactants, ama-polysiloxane ashintshwe nge-polyether-modified, ama-acetylene diols, njll. upende osekelwe), ngokuvamile oncibilika emanzini, ibhamuza eliphansi kanye nebhamuza elingazinzi, ukuzwela okuphansi emanzini, futhi ngeke kubangele izinkinga zokubuyisela kabusha nokulahlekelwa ukunamathela.

Ama-ejenti okumanzisa ama-substrate asetshenziswa kakhulu ama-ethylene oxide adducts (isibonelo, uhlobo lwe-polyoxyethylene-nonylphenol), uhlobo lwe-polyorganosilicon kanye nenhlanganisela yohlobo lwe-non-ionic fluorocarbon polymer kanye nezinye izinhlobo, okuyi-agent yokumanzisa yohlobo lwe-fluorocarbon polymer ukunciphisa ukungezwani kwendawo okuwumphumela obaluleke kakhulu.

Umbono oyiphutha, othonywa ukukhangisa, ukuthi umthelela wokunciphisa ukungezwani kwendawo kukodwa unqunywa uma kuyikhono lokusabalalisa le-coating ku-substrate elibaluleke kakhulu, futhi lesi sakhiwo sihlobene nokuhambisana kwesistimu kanye nokufaneleka ukungezwani kwendawo.

Ikhono lokusabalalisa le-ejenti yokumanzisa linganqunywa ngokulinganisa indawo yokusabalalisa yevolumu enikeziwe (0.05 ml) kapende ku-substrate eboshwe ngaphambili ngemva kokwengeza ukugxila okunikeziwe kwe-ejenti yokumanzisa engaphansi kupende.Ama-ejenti wokumanzisa.

Ezimweni eziningi, inani le-static surface tension alikwazi ukuhambisana nekhono lokumanzisa likapende ngesikhathi sokwakha, ngenxa yokuthi upende usendaweni yengcindezi ngesikhathi sokwakha, futhi ukwehla kwengcindezi yendawo eguqukayo ngalesi sikhathi, kuzuzisa kakhulu ukumanzisa.Ama-surfactants e-fluorocarbon anciphisa ngokuyinhloko ukungezwani kwendawo emile, okungesinye sezizathu zokuthi kungani ukusetshenziswa kwama-surfactants e-fluorocarbon kuncane kakhulu kunama-silicone.

Ukukhetha i-solvent efanelekile nakho kungaba nomthelela omuhle wokumanzisa i-substrate.Ngenxa yokuthi i-solvent iyahambisana nesistimu, ukungezwani kwendawo okuguquguqukayo kuphansi.

Ukunakwa okukhethekile: uma i-ejenti yokumanzisa i-substrate ingakhethwanga kahle, izokwakha ungqimba olulodwa lwamangqamuzana ku-substrate, ngaleyo ndlela ukuhambisana nesistimu yokugqoka akusekuhle, okuzothinta ukunamathela.

Ama-ejenti wokumanzisa amaningana ahlukene angaxutshwa ukuxazulula ukumanzisa kwe-substrate okuyinkimbinkimbi.
