Yini i-antifoam ekwelashweni kwamanzi amdaka?

Izwe elitemi antifoam, eyaziwa nangokuthi i-Defombar, iyisithasiselo samakhemikhali esisetshenziswa ezinqubweni zokwelashwa kwamanzi amdaka ukulawula ukwakheka kwe-foam. I-Foam iyinkinga ejwayelekile ezitshalweni zokwelashwa kwamanzi amdaka futhi ingavela emithonjeni ehlukahlukene efana nezinto eziphilayo, ama-surfactants, noma ukuphazamiseka kwamanzi. Ngenkathi i-FOAM ingahle ibonakale iyingozi, empeleni ingaphazamisa ukusebenza kwezindlela zokwelashwa kwamanzi amdaka ngokuphazamisa ukusebenza kwemishini, kunciphisa ukusebenza kwezingqinamba zokwelashwa kwamakhemikhali, futhi kungadala izingqinamba ezichichimekayo.

Ama-ejenti angu-Antifoam asebenza ngokuphetha ama-Foam Bubbles, abenze bawa noma banciphise, ngaleyo ndlela banciphise ivolumu yegwebu futhi bavimbele ekuphazamiseni izinqubo zokwelashwa. Lawa ma-ejenti ajwayele ukuhlanganiswa kwengxubevange ye-surfcactants, amafutha, izilonda, noma ezinye izinto ze-hydrophobic. Uma kungezwe emanzini angcolile, ama-antifoam agents athuthela phezulu kwegwebu futhi aphazamise ukungezwani, okuholela ekuqhekekeni kwama-bubble we-foam.

Kunezinhlobo eziningi zama-antifoam agents asetshenziswa ekwelashweni kwamanzi amdaka, ngalinye linezakhiwo zalo ezithile kanye nezicelo:

Ama-antifoemu asuselwa ku-silicone:

Lokhu kuphakathi kwabahlinzeki be-antifoam abasetshenziswa kakhulu ngenxa yokusebenza kwabo yonke imibandela. Ama-antifoamu asuselwa ku-silicone aqinile, awohliweyo emanzini, futhi ahlelwe ukuthi ahambisane nezinqubo ezahlukahlukene zokwelashwa kwamanzi.

Izinzuzo ze-Orgasilicon Defoomers:

Ukungena kwamakhemikhali okuhle, ungaphenduli nezinye izinto, ungasetshenziswa ku-acidic, alkali, kanye nezinhlelo ezinosawoti

Ukuhlanzeka okuhle komzimba, okulungele ukusetshenziswa ezimbonini zokudla kanye nemithi yezemithi, ukungcola okungenayo imvelo

Ukuqina okushisayo okushisayo, ukuguquguquka okuphansi, futhi kungasetshenziswa ngaphezu kobubanzi bokushisa obubanzi

I-Viscosity ephansi, isakazeka ngokushesha esibonakalayo segesi

Ukuxineka komhlaba kuphansi njenge-1.5-20 MN / M (Amanzi angama-76 mn / m)

Hhayi ukuncibilika ku-surfing of foaming systems

Umthamo ophansi, ukubonakala okuphansi, nokuvutha okuphansi

Ama-Polymeric Antifoams:

Lawa ma-antifoam agents asuselwa kuma-polymers aphazamisa ukwakheka kwe-foam nge-adderbing ebusweni bama-bubble we-foam futhi aguqule ukuqina kwawo. Ama-polymeric ama-antifoams ajwayele ukusetshenziswa ezimweni lapho ama-ejenti wendabuko angu-antifoam angeke asebenze kahle, njengasezimo ze-alkali noma ezi-acidic wastewater.

Amanye ama-antifoams:

Kwezinye izimo, ama-antifoemu asuselwa ku-silicone angeke alunge ngenxa yezinkinga zobuchwepheshe noma izidingo ezithile zenqubo. Ama-antifoams angewona ama-silicone, anjenge-antifoams asuselwa kumaminerali acijiyo noma anesineka acid acid, anikele ezinye izindlela ezingase zibe nobungani bemvelo noma zilungele izinhlelo ezithile ezithile.

Ama-antifoam ayimpuphu:

Amanye ama-antifoam anchents atholakala kwifomu elinempuphu, elingaba nenzuzo kuzinhlelo zokusebenza lapho izithasiselo eziwuketshezi zingasebenzi noma lapho kudingeka khona umsebenzi we-antifoam.

Ukukhethwa kwe-ejenti ye-antifoam efanele kuncike ezintweni ezifana nohlobo lwamanzi angcolile, inqubo ethile yokwelashwa esetshenziswa, izidingo zokulawula, kanye nokucatshangelwa kwezindleko. Ngaphezu kokukhetha i-antifoam agent efanele, umthamo ofanele nezindlela zohlelo lokusebenza zibalulekile ekuqinisekiseni ukulawulwa kwegwebu okusebenzayo ngaphandle kokuthinta ukusebenza kwamanzi angcolile.

Ngenkathi ama-antifoam agents asebenza ngempumelelo ekulawuleni izinqubo zokwelashwa kwamanzi angcolile, kubalulekile ukuzisebenzisa ngokwahlulela ukugwema imiphumela engahlosiwe njengezinto eziphikisayo ezifana nemvelo. Ukuqapha njalo kwamazinga we-foam kanye nokulungiswa komthamo we-antifoam njengoba kudingeka kungasiza ukwandisa amandla we-foam ngenkathi kunciphisa noma yimiphi imithelela emibi ekusebenzeni kahle kwamanzi angcolile kanye nokuthobela imvelo.
