Iyini i-Antifoam ekuhlanzeni amanzi angcolile?

I-Antifoam, eyaziwa nangokuthi i-defoamer, iyisengezo samakhemikhali esisetshenziswa ezinqubweni zokuhlanza amanzi angcolile ukulawula ukwakheka kwegwebu.Igwebu liyinkinga evamile ezikhungweni zokuhlanza amanzi angcolile futhi lingavela emithonjeni ehlukahlukene efana ne-organic matter, ama-surfactants, noma ukuyaluza kwamanzi.Nakuba igwebu lingase libonakale lingenangozi, empeleni lingakhinyabeza ukusebenza kahle kwezinqubo zokuhlanza amanzi angcolile ngokuphazamisa ukusebenza kwemishini, ukunciphisa ukusebenza kahle kokwelashwa ngamakhemikhali, futhi okungenzeka kubangele izinkinga ezichichimayo noma ze-carryover.

Ama-Antifoam agents asebenza ngokuphazamisa ama-bubbles we-foam, abangele ukuba adilike noma ahlangane, ngaleyo ndlela anciphise umthamo wegwebu futhi avimbele ukuthi angaphazamisi izinqubo zokwelashwa.Lawa ma-ejenti ngokuvamile ahlanganisa ingxube yama-surfactants, amafutha, ama-silicone, noma ezinye izinto ze-hydrophobic.Uma zengezwa emanzini angcolile, ama-antifoam agents athuthela ebusweni be-foam futhi aphazamise ukungezwani kwendawo, okuholela ekuqhekekeni kwamagwebu e-foam.

Kunezinhlobo ezimbalwa zama-antifoam ejenti asetshenziswa ekwelashweni kwamanzi angcolile, ngalinye linezici zalo eziqondile kanye nezicelo:

Ama-antifoam asekelwe ku-silicone:

Lezi ziphakathi kwama-antifoam ejenti asetshenziswa kakhulu ngenxa yokusebenza kahle kwawo ezimeni eziningi.Ama-antifoam asekelwe ku-silicone azinzile, awancibiliki emanzini, futhi angakhiwa ukuze ahambisane nezinqubo ezihlukahlukene zokuhlanza amanzi angcolile.

Izinzuzo ze-organosilicon defoamers:

I-inertness enhle yamakhemikhali, engasabelani nezinye izinto, ingasetshenziswa ezinhlelweni ezine-acidic, alkaline, nezinosawoti.

Ukungangeni kahle komzimba, kulungele ukusetshenziswa ezimbonini zokudla nezamakhemisi, ukungangcoli kwemvelo

Ukuzinza kokushisa okumaphakathi, ukuguquguquka okuphansi, futhi kungasetshenziswa ebangeni elibanzi lokushisa

I-viscosity ephansi, isakazeka ngokushesha esibonakalayo esinoketshezi lwegesi

Ukushuba kwamanzi kuphansi njengo-1.5-20 mN/m (amanzi angama-76 mN/m)

Ayincibiliki kuma-surfactants wezinhlelo ezigwebulile

Umthamo ophansi, i-viscosity ephansi, nokuvutha okuphansi

Ama-antifoam e-polymeric:

Lawa ma-antifoam asekelwe kuma-polymers aphazamisa ukwakheka kwegwebu ngokukhangisa phezu kwamabhamuza egwebu futhi aguqule ukuzinza kwawo.Ama-polymeric antifoam avame ukusetshenziswa ezimeni lapho ama-ejenti endabuko e-antifoam engase angasebenzi kahle, njengasezimweni zamanzi angcolile ane-alkaline kakhulu noma ane-acidic.

Amanye ama-antifoams:

Kwezinye izimo, ama-antifoam asekelwe ku-silicone angase angafaneleki ngenxa yokukhathazeka kwezobuchwepheshe noma izidingo ezithile zenqubo.Ama-antifoam angewona ama-silicone, afana nama-antifoam asuselwa ku-mineral oil-based or fatty-based antifoams, anikeza ezinye izindlela ezingase zibe nobungane ngokwemvelo noma ezilungele kangcono izinhlelo zokusebenza ezithile.

Ama-antifoams aphethwe:

Amanye ama-antifoam ejenti atholakala efomini eliyimpuphu, okungaba inzuzo ezinhlelweni lapho izithasiselo eziwuketshezi zingasebenzi noma lapho kudingeka khona umsebenzi we-antifoam omude.

Ukukhethwa kwe-ejenti efanele ye-antifoam kuncike ezintweni ezifana nesimo samanzi angcolile, inqubo ethile yokwelapha esetshenziswayo, izidingo zokulawula, nokucatshangelwa kwezindleko.Ngaphezu kokukhetha i-ejenti efanele ye-antifoam, isilinganiso esifanele nezindlela zokufaka isicelo kubalulekile ukuze kuqinisekiswe ukulawulwa kwegwebu okuphumelelayo ngaphandle kokuthikameze kabi ukusebenza kokwelashwa kwamanzi angcolile.

Nakuba ama-antifoam esebenza ngempumelelo ekulawuleni igwebu ezinqubweni zokuhlanza amanzi angcolile, kubalulekile ukuwasebenzisa ngokuhlakanipha ukuze ugweme imiphumela engahlosiwe njengokuphazamiseka kwezinqubo zokwelashwa kwebhayoloji noma ukukhululwa kwezinto eziyingozi endaweni ezungezile.Ukuqapha njalo amazinga egwebu kanye nokulungiswa komthamo we-antifoam njengoba kudingeka kungasiza ekuthuthukiseni ukulawulwa kwegwebu kuyilapho kunciphisa noma yimiphi imithelela engemihle ekusebenzeni kahle kokwelashwa kwamanzi angcolile kanye nokuhambisana nemvelo.
