I-Siliconei-defoameri-emulsion emhlophe ye-viscous.Isetshenziswe emikhakheni yezimboni eyahlukene kusukela ngawo-1960, kodwa intuthuko enkulu nephelele yaqala ngawo-1980.Njenge-organosiliconi-defoamer, izinkambu zayo zokufaka isicelo nazo zibanzi kakhulu, zidonsa ukunakwa okwengeziwe kuzo zonke izigaba zokuphila.Emkhakheni wamakhemikhali, iphepha, ukugqoka, ukudla, izindwangu, imithi kanye neminye imikhakha yezimboni, i-siliconei-defoameriyisengezo esibalulekile enqubweni yokukhiqiza.Ayikwazi ukususa igwebu kuphela endaweni ewuketshezi yenqubo yokukhiqiza, ngaleyo ndlela ithuthukise ukuhlunga, ukuhlukaniswa, ukufakwa kwegesi, kanye nemiphumela ye-liquid drainage yokugeza, isizinda, i-distillation, ukuhwamuka, ukuphelelwa amanzi emzimbeni, ukomisa nezinye izinqubo zobuchwepheshe ziqinisekisa umthamo wezinto ezahlukahlukene zokugcina kanye neziqukathi zokucubungula.

Izinzuzo zeama-silicone defoamers:
1. Uhlu olubanzi lwezinhlelo zokusebenza: ngenxa yesakhiwo samakhemikhali esikhethekile samafutha we-silicone, awahambisani namanzi noma izinto eziqukethe amaqembu amhlophe, noma ama-hydrocarbon noma izinto eziphilayo eziqukethe amaqembu e-hydrocarbon.Ngenxa yokungancibiliki kwamafutha e-silicone ezintweni ezihlukahlukene, inezinhlobonhlobo zezicelo.Ingasetshenziselwa ukukhipha amagwebu ezinhlelweni zamanzi kanye nasezinhlelweni zikawoyela.
2. Ukungezwani okuphansi kwendawo: Umthamo wangaphezulu kawoyela we-silicone ngokuvamile u-20-21 dyne/cm, mancane kunawamanzi (72 dyne/cm) kanye noketshezi oluvamile olunamagwebu, futhi unokusebenza okuhle kokukhipha amagwebu.
3. Ukuzinza okuhle kokushisa: Ukuthatha i-simethicone evame ukusetshenziswa njengesibonelo, ingakwazi ukumelana no-150 ° C isikhathi eside no-300 ° C isikhathi esifushane, futhi isibopho sayo se-Si-O ngeke sibole.Lokhu kuqinisekisa ukuthii-silicone defoameringasetshenziswa ebangeni lokushisa elibanzi.
4. Ukuzinza okuhle kwamakhemikhali: Njengoba isibopho se-Si-O sizinzile, ukuzinza kwamakhemikhali kawoyela we-silicone kuphezulu kakhulu, futhi kunzima ukusabela ngamakhemikhali nezinye izinto.Ngakho-ke, inqobo nje uma ukwakheka kunengqondo,ama-silicone defoamersavunyelwe ukuthi asetshenziswe ezinhlelweni eziqukethe ama-asidi, ama-alkali, nosawoti.
5. I-inert Physiologically: Amafutha e-silicone afakazelwe ukuthi awanabo ubuthi kubantu nasezilwaneni, futhi umthamo wawo obulalayo uyingxenye enkulu kuno-34 g/kg.Ngakho-ke,ama-silicone defoamers(ezinama-emulsifiers angenabuthi afanelekile, njll.) angasetshenziswa ngokuphephile ezimbonini zokudla, zezokwelapha, ezemithi nezimonyo.
6. Amandla aqinile okuqeda amagwebu:I-Silicone defoamerayikwazi nje ukuphula ngokuphumelelayo i-foam eyenziwe, kodwa futhi ingavimbela ngokuphawulekayo i-foam futhi ivimbele ukwakheka kwegwebu.Ukusetshenziswa kwayo kuncane kakhulu, inqobo nje uma wengeza ingxenye eyodwa esigidini (1ppm) yesisindo sendawo ekhipha amagwebu, kungaveza umphumela wokuqeda ugwebu.Ububanzi bayo obuvame ukusetshenziswa ngu-1 kuya ku-100 ppm.Akukhona nje kuphela ukuthi izindleko ziphansi, kodwa futhi azingcolisi into ekhishwe amagwebu.

Ububi beama-silicone defoamers:
a.I-Polysiloxane inzima ukuyihlakaza: I-Polysiloxane inzima ukuncibilika emanzini, okuvimbela ukuhlakazeka kwayo ohlelweni lwamanzi.I-ejenti ehlakazayo kumele yengezwe.Uma i-ejenti ehlakazayo ingeziwe, i-emulsion izozinza futhi umphumela we-defoaming uzoshintsha.Kubi, kuyadingeka ukusebenzisa i-emulsifier encane ukwenza umphumela wokuqeda amagwebu ube muhle futhi i-emulsion iqine.
b.I-Silicone iyancibilika kuwoyela, enciphisa umphumela wayo wokukhipha amagwebu ohlelweni lukawoyela.
c.Ukumelana nokushisa okuphezulu kwesikhathi eside kanye nokungazweli kahle kwe-alkali.
