Yintoni i-Antifoam kunyango lwamanzi amdaka?

I-Antifoam, ekwaziwa ngokuba yi-defoamer, sisongezo sekhemikhali esisetyenziswa kwiinkqubo zokucocwa kwamanzi amdaka ukulawula ukubunjwa kwegwebu.Igwebu ngumba oqhelekileyo kwizityalo zokucocwa kwamanzi amdaka kwaye unokuvela kwimithombo eyahlukeneyo efana ne-organic, i-surfactants, okanye ukuphazamiseka kwamanzi.Ngelixa ugwebu lusenokubonakala lungenabungozi, lunokuthintela ukusebenza kakuhle kweenkqubo zokucocwa kwamanzi amdaka ngokuphazamisana nokusebenza kwezixhobo, ukunciphisa ukusebenza konyango lwekhemikhali, kwaye kunokubangela ukuphuphumala okanye imiba ye-carryover.

Ama-Antifoam agents asebenza ngokuphazamisa iibhubhu ze-foam, ezibangela ukuba zidibanise okanye zidibanise, ngaloo ndlela zinciphisa umthamo we-foam kwaye zithintele ukuphazamisa iinkqubo zonyango.Ezi arhente ngokuqhelekileyo ziquka umxube we-surfactants, i-oyile, i-silicones, okanye ezinye izinto ze-hydrophobic.Xa zongezwa kumanzi amdaka, i-antifoam agents zifudukela kumphezulu we-foam kwaye ziphazamise ukunyanzeliswa komhlaba, okukhokelela ekuqhekekeni kweebhubhu ze-foam.

Kukho iindidi ezininzi zee-antifoam ezisetyenziswa kunyango lwamanzi amdaka, nganye ineempawu zayo ezithile kunye nokusetyenziswa kwayo:

Ii-antifoam ezisekelwe kwi-silicone:

Ezi ziphakathi kwee-antifoam ezisetyenziswa ngokuqhelekileyo ngenxa yokusebenza kwazo kuluhlu olubanzi lweemeko.Ii-antifoam ezisekelwe kwi-silicone zizinzile, azinakunyibilika emanzini, kwaye zinokuqulunqwa ukuze zihambelane neenkqubo ezahlukeneyo zokucocwa kwamanzi amdaka.

Izinto ezilungileyo ze-organosilicon defoamers:

I-inertness elungileyo yeekhemikhali, engasabelani nezinye izinto, ingasetyenziswa kwiinkqubo ezineasidi, ialkaline, kunye netyuwa.

Ukungangeni kakuhle komzimba, kulungele ukusetyenziswa kumashishini okutya kunye namayeza, ukungangcoliseki kokusingqongileyo

Uzinzo oluphakathi lwe-thermal, ukuguquguquka okuphantsi, kwaye lunokusetyenziswa kuluhlu olubanzi lobushushu

I-viscosity ephantsi, isasazeka ngokukhawuleza kwi-interface ye-gas-liquid

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

Ayinyibiliki kwii-surfactants zenkqubo yogwebu

Idosi ephantsi, i-viscosity ephantsi, kunye nokutsha okuphantsi

Iipolymeric antifoams:

Ezi zixhobo ze-antifoam zisekelwe kwiipolymers eziphazamisa ukubunjwa kwe-foam ngokubhengeza phezu kobuso be-foam bubbles kunye nokuguqula ukuzinza kwazo.Ii-polymeric antifoams zihlala zisetyenziswa kwiimeko apho ii-agent ze-antifoam zemveli zinokuthi zingasebenzi, njengakwimeko ye-alkaline kakhulu okanye i-acidic yamanzi amdaka.

Ezinye ii-antifoams:

Kwezinye iimeko, i-antifoams esekelwe kwi-silicone ayinakufaneleka ngenxa yokukhathazeka kwezobuchwepheshe okanye iimfuno ezithile zenkqubo.I-antifoams engekho-silicone, efana ne-oyile ye-mineral-based okanye i-fatty-based-antifoams-based-antifoams, inika ezinye iindlela ezinokuthi zibe zihambelana nokusingqongileyo okanye zilungele kangcono izicelo ezithile.

Ii-antifoams ezinomgubo:

Ezinye ii-antifoam agents zifumaneka kwifom ye-powdered, enokuthi ibe luncedo kwizicelo apho izongezo zolwelo zingasebenzi okanye apho kufuneka umsebenzi we-antifoam ixesha elide.

Ukukhethwa kwe-arhente ye-antifoam efanelekileyo kuxhomekeke kwizinto ezifana nobume bamanzi amdaka, inkqubo ethile yonyango esetyenziswayo, iimfuno zokulawula, kunye nokuqwalaselwa kweendleko.Ukongeza ekukhetheni i-agent ye-antifoam efanelekileyo, idosi efanelekileyo kunye neendlela zokusetyenziswa zibalulekile ukuze kuqinisekiswe ulawulo olusebenzayo lwegwebu ngaphandle kokuchaphazela kakubi ukusebenza kokucoca kwamanzi amdaka.

Nangona i-antifoam agents zisebenza ngokufanelekileyo ekulawuleni i-foam kwiinkqubo zokunyanga kwamanzi amdaka, kubalulekile ukuzisebenzisa ngokufanelekileyo ukuphepha iziphumo ezingalindelekanga ezifana nokuphazamiseka kweenkqubo zonyango lwebhayoloji okanye ukukhutshwa kwezinto ezinobungozi kwindalo.Ukujongwa rhoqo kwamanqanaba e-foam kunye nohlengahlengiso lwedosi ye-antifoam njengoko kufuneka kunokunceda ukwandisa ulawulo lwe-foam ngelixa unciphisa naziphi na iimpembelelo ezingalunganga ekusebenzeni kakuhle kokucocwa kwamanzi amdaka kunye nokuthotyelwa kokusingqongileyo.
