Iyini i-Antifoam ekuphathweni kwamanzi amdaka?

I-Antifoam, eyaziwa nangokuthi i-defoamer, iyisengezo samakhemikhali esisetshenziswa ezinqubweni zokwelashwa kwamanzi amdaka ukulawula ukwakheka kwegwebu. Igwebu liyinkinga evamile ezitshalweni zokwelashwa kwamanzi amdaka futhi lingavela emithonjeni ehlukahlukene njengezinto eziphilayo, ama-surfactant, noma ukuvunguzwa kwamanzi. Nakuba igwebu lingase libonakale lingenangozi, empeleni lingaphazamisa ukusebenza kahle kwezinqubo zokwelashwa kwamanzi amdaka ngokuphazamisa ukusebenza kwemishini, ukunciphisa ukusebenza kahle kokwelashwa kwamakhemikhali, futhi okungenzeka kubangele izinkinga zokugcwala noma zokuthwala amanzi.

Ama-antifoam agent asebenza ngokuphazamisa amabhamuza e-foam, okubangela ukuba abhidlike noma ahlangane, ngaleyo ndlela anciphise ivolumu ye-foam futhi ayivimbele ukuthi ingaphazamisi izinqubo zokwelapha. Lawa ma-agent ngokuvamile aqukethe ingxube yama-surfactants, amafutha, ama-silicone, noma ezinye izinto ezithinta amanzi. Uma engezwa emanzini angcolile, ama-antifoam agents ayathuthela ebusweni be-foam futhi aphazamise ukucindezeleka kobuso, okuholela ekuqhekekeni kwamabhamuza e-foam.

Kunezinhlobo eziningana zama-antifoam agents asetshenziswa ekwelapheni amanzi amdaka, ngalinye linezakhiwo zalo kanye nezinhlelo zokusebenza:

Ama-antifoam asekelwe ku-silicone:

Lezi ziphakathi kwezinto ezisetshenziswa kakhulu zokulwa ne-foam ngenxa yokusebenza kwazo ezimweni eziningi ezahlukene. Ama-antifoam asekelwe ku-silicone azinzile, awancibiliki emanzini, futhi angakhiwa ukuze ahambisane nezinqubo ezahlukene zokwelashwa kwamanzi amdaka.

Izinzuzo zama-defoamers e-organosilicon:

Ukungangeni kahle kwamakhemikhali, okungahlangani nezinye izinto, kungasetshenziswa ezinhlelweni ze-acidic, alkaline, kanye nosawoti

Ukungangeni kahle komzimba, okufanele ukusetshenziswa embonini yokudla neyokwelapha, akungcolisi imvelo

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

Ukuchachamba okuphansi, okusabalala ngokushesha endaweni yokuxhumana negesi noketshezi

Ukucindezeleka kobuso kuphansi njengo-1.5-20 mN/m (amanzi angama-76 mN/m)

Ayincibiliki kuma-surfactants ezinhlelo ze-foam

Isilinganiso esiphansi, i-viscosity ephansi, kanye nokusha okuphansi

Ama-antifoam e-polymeric:

Lawa ma-antifoam agents asekelwe kuma-polymers aphazamisa ukwakheka kwe-foam ngokunamathela ebusweni bamabhamuza e-foam futhi ashintshe ukuqina kwawo. Ama-antifoam e-polymeric avame ukusetshenziswa ezimweni lapho ama-antifoam agents endabuko angase angasebenzi kahle, njengasezimweni zamanzi angcolile ane-alkaline kakhulu noma ane-acidic.

Amanye ama-antifoam:

Kwezinye izimo, ama-antifoam asekelwe ku-silicone angase angafaneleki ngenxa yokukhathazeka kwezobuchwepheshe noma izidingo ezithile zenqubo. Ama-antifoam angewona ama-silicone, njenge-antifoam asekelwe ku-mineral oil noma ama-antifoam asekelwe ku-fatty acid, anikeza ezinye izindlela ezingase zibe nobungane nemvelo noma zifaneleke kangcono kwezinye izinhlelo zokusebenza.

Ama-antifoam afakwe ufulawa:

Amanye ama-antifoam agents atholakala ngesimo sempuphu, okungaba wusizo lapho izithasiselo zoketshezi zingasebenzi noma lapho kudingeka khona umsebenzi we-antifoam oqhubekayo.

Ukukhethwa kwe-antifoam agent efanele kuncike ezicini ezifana nohlobo lwamanzi angcolile, inqubo ethile yokwelapha esetshenziswayo, izidingo zomthetho, kanye nokucatshangelwa kwezindleko. Ngaphezu kokukhetha i-antifoam agent efanele, isilinganiso esifanele kanye nezindlela zokusebenzisa kubalulekile ukuqinisekisa ukulawulwa kwe-foam okuphumelelayo ngaphandle kokuphazamisa ukusebenza kokwelashwa kwamanzi angcolile.

Nakuba ama-antifoam agents ephumelela ekulawuleni i-foam ezinqubweni zokwelashwa kwamanzi amdaka, kubalulekile ukuwasebenzisa ngokuhlakanipha ukuze ugweme imiphumela engahlosiwe njengokuphazamiseka kwezinqubo zokwelashwa kwezinto eziphilayo noma ukukhishwa kwezinto eziyingozi emvelweni. Ukuqapha njalo amazinga e-foam nokulungiswa komthamo we-antifoam njengoba kudingeka kungasiza ekwenzeni ngcono ukulawulwa kwe-foam ngenkathi kunciphisa noma yimiphi imiphumela emibi ekusebenzeni kahle kokwelashwa kwamanzi amdaka kanye nokuhambisana nemvelo.
