Yintoni i-Antifoam ekunyangweni kwamanzi amdaka?

I-Antifoam, okwaziwa ngokuba yi-defoamer, sisithako seekhemikhali esisetyenziswa kwiinkqubo zonyango lwamanzi amdaka ukulawula ukwakheka kwefoam. Ifoam yingxaki eqhelekileyo kwizityalo zonyango lwamanzi amdaka kwaye inokuvela kwimithombo eyahlukeneyo efana nezinto eziphilayo, izinto ezibangela ukudumba kwamanzi, okanye ukushukunyiswa kwamanzi. Nangona ifoam ingabonakala ingenabungozi, inokuthintela ukusebenza kakuhle kweenkqubo zonyango lwamanzi amdaka ngokuphazamisa ukusebenza kwezixhobo, ukunciphisa ukusebenza kakuhle konyango lweekhemikhali, kwaye inokubangela iingxaki zokugcwala okanye ukuthwala amanzi.

Iiarhente ze-antifoam zisebenza ngokuphazamisa amaqamza e-foam, zibangele ukuba adilike okanye ahlangane, ngaloo ndlela zinciphisa umthamo we-foam kwaye zithintele ukuba ingaphazamisi iinkqubo zonyango. Ezi arhente zihlala ziqulathe umxube wee-surfactants, iioyile, ii-silicones, okanye ezinye izinto ezibangela ukunganyangeki kwamanzi. Xa zongezwa kumanzi amdaka, iiarhente ze-antifoam ziyafudukela kumphezulu we-foam kwaye ziphazamise uxinzelelo lomphezulu, nto leyo ekhokelela ekuqhekekeni kwamaqamza e-foam.

Kukho iintlobo ezahlukeneyo zee-antifoam agents ezisetyenziswa kunyango lwamanzi amdaka, nganye ineempawu zayo ezithile kunye nokusetyenziswa kwayo:

Izinto zokuthintela amagwebu ezisekelwe kwi-silicone:

Ezi zezinye zezona arhente zisetyenziswa kakhulu ekuthinteleni amagwebu ngenxa yokusebenza kwazo kwiimeko ezahlukeneyo. Ii-antifoams ezisekelwe kwi-silicone zizinzile, azinyibiliki emanzini, kwaye zinokwenziwa ukuze zihambelane neenkqubo ezahlukeneyo zokunyanga amanzi amdaka.

Iingenelo ze-organosilicon defoamers:

Ukungangeni kakuhle kweekhemikhali, okungasebenzi nezinye izinto, kungasetyenziswa kwiinkqubo ze-asidi, i-alkaline, kunye netyuwa

Ukungangeni kakuhle komzimba, kufanelekile ukusetyenziswa kwimizi-mveliso yokutya kunye namayeza, akukho ngcoliseko kwindalo esingqongileyo

Uzinzo oluphakathi lobushushu, ukuguquguquka okuphantsi, kwaye lungasetyenziswa kumanqanaba obushushu abanzi

I-viscosity ephantsi, isasazeka ngokukhawuleza kwindawo yokujonga igesi nolwelo

Uxinzelelo lomphezulu luphantsi njenge-1.5-20 mN/m (amanzi angama-76 mN/m)

Ayinyibiliki kwii-surfactants zeenkqubo ze-foam

Idosi ephantsi, i-viscosity ephantsi, kunye nokutsha okuphantsi

Izinto ezilwa namagwebu e-polymeric:

Ezi arhente ze-antifoam zisekelwe kwiipolymers eziphazamisa ukwakheka kwe-foam ngokufunxa phezu kwamaqamza e-foam kwaye zitshintshe ukuzinza kwawo. Ii-antifoam ze-polymeric zihlala zisetyenziswa kwiimeko apho ii-agent ze-antifoam zemveli zisenokungasebenzi, njengakwimeko yamanzi amdaka ane-alkaline eninzi okanye ane-asidi.

Ezinye izinto ezilwa namagwebu:

Kwezinye iimeko, ii-antifoams ezisekelwe kwi-silicone zisenokungafaneleki ngenxa yenkxalabo yetekhnoloji okanye iimfuno ezithile zenkqubo. Ii-antifoams ezingezizo ii-silicone, ezifana nee-antifoams ezisekelwe kwi-mineral oil okanye ii-antifoams ezisekelwe kwi-fatty acid, zibonelela ngezinye iindlela ezinokuba nobuhlobo nokusingqongileyo okanye zifaneleke ngakumbi kwizicelo ezithile.

Izinto zokuthintela amagwebu ezigutyungelwe ngumgubo:

Ezinye izinto ezilwa nefoam ziyafumaneka zikwimo yomgubo, nto leyo enokuba luncedo xa kusetyenziswa izinto apho izongezo zolwelo zingasebenzi okanye apho kufuneka umsebenzi ohlala ixesha elide wokulwa nefoam.

Ukukhethwa kwearhente efanelekileyo yokuthintela ukufunxwa kuxhomekeke kwizinto ezifana nohlobo lwamanzi amdaka, inkqubo ethile yonyango esetyenziswayo, iimfuno zomthetho, kunye nokuqwalaselwa kweendleko. Ukongeza ekukhetheni iarhente efanelekileyo yokuthintela ukufunxwa, idosi efanelekileyo kunye neendlela zokusebenzisa zibalulekile ukuqinisekisa ulawulo olusebenzayo lwefoam ngaphandle kokuchaphazela kakubi ukusebenza konyango lwamanzi amdaka.

Nangona ii-antifoam agents zisebenza kakuhle ekulawuleni i-foam kwiinkqubo zonyango lwamanzi amdaka, kubalulekile ukuzisebenzisa ngobulumko ukuze kuthintelwe iziphumo ebezingalindelekanga ezifana nokuphazamiseka kwiinkqubo zonyango lwebhayoloji okanye ukukhululwa kwezinto eziyingozi kwindalo esingqongileyo. Ukubeka iliso rhoqo kumanqanaba e-foam kunye nokulungiswa komthamo we-antifoam njengoko kufuneka kunokunceda ukuphucula ulawulo lwe-foam ngelixa kunciphisa naziphi na iimpembelelo ezimbi ekusebenzeni kakuhle konyango lwamanzi amdaka kunye nokuthobela imimiselo yokusingqongileyo.
