Siliconedefoamerke emulsion e tšoeu ea viscous.E 'nile ea sebelisoa makaleng a fapaneng a indasteri ho tloha lilemong tsa bo-1960, empa tsoelo-pele e potlakileng le e pharaletseng e qalile ka bo-1980.Joaloka organosilicondefoamer, masimo a ts'ebeliso ea eona le ona a pharalletse haholo, a hohela tlhokomelo e eketsehileng ho tsoa mekhoeng eohle ea bophelo.Makaleng a lik'hemik'hale, pampiri, liaparo, lijo, masela, meriana le tse ling tsa indasteri, siliconedefoamerke tlatsetso e hlokahalang ts'ebetsong ea tlhahiso.E ke ke ea tlosa foam holim'a metsi a mokhoa oa ts'ebetso ts'ebetsong ea tlhahiso, ka hona e ntlafatsa ho hloekisa, karohano, gasification, le liphello tsa metsi a metsi a ho hlatsoa, ​​​​ho ntša, ho ntša metsi, ho tsoa mouoane, ho felloa ke metsi, ho omisa le mekhoa e meng ea theknoloji ho netefatsa hore bokhoni ba mefuta e fapaneng ea polokelo le lijana tsa ho sebetsa.

Melemo eali-silicone defoamers:
1. Mefuta e mengata ea lisebelisoa: ka lebaka la sebopeho se khethehileng sa lik'hemik'hale tsa oli ea silicone, ha e lumellane le metsi kapa lintho tse nang le lihlopha tsa polar, kapa ka li-hydrocarbon kapa lintho tse phelang tse nang le lihlopha tsa hydrocarbon.Ka lebaka la ho insolubility ea oli ea silicone linthong tse fapaneng, e na le mefuta e mengata ea lisebelisoa.E ka sebelisoa bakeng sa ho tlosa lekoba litsamaisong tsa metsi hammoho le litsing tsa oli.
2. Khatello e tlaase ea holim'a metsi: Matla a holim'a oli ea silicone ka kakaretso ke 20-21 dyne / cm, e nyenyane ho feta ea metsi (72 dyne / cm) le metsi a mangata a foaming, 'me a na le ts'ebetso e ntle ea ho senya.
3. Botsitso bo botle ba mocheso: Ho nka simethicone e sebelisoang ka tloaelo e le mohlala, e ka mamella 150 ° C ka nako e telele le 300 ° C ka nako e khutšoanyane, 'me tlamo ea eona ea Si-O e ke ke ea senyeha.Sena se tiisa hore hosilicone defoamere ka sebelisoa ka mefuta e mengata ea mocheso.
4. Botsitso bo botle ba lik'hemik'hale: Kaha selekane sa Si-O se batla se tsitsitse, botsitso ba lik'hemik'hale tsa oli ea silicone bo phahame haholo, 'me ho thata ho sebetsana le lik'hemik'hale ka lintho tse ling.Ka hona, ha feela tlhahiso e ntse e utloahala,li-silicone defoamersli lumelloa ho sebelisoa mekhoeng e nang le li-acids, alkalis, le letsoai.
5. Boiketlo ba 'mele: Oli ea silicone e bontšitsoe hore ha e na chefo ho batho le liphoofolo,' me tekanyo ea eona e bolaeang halofo e kholo ho feta 34 g / kg.Ka hona,li-silicone defoamers(ka li-emulsifiers tse loketseng tse se nang chefo, joalo-joalo) li ka sebelisoa ka mokhoa o sireletsehileng indastering ea lijo, ea bongaka, ea meriana le ea litlolo.
6. Matla a matla a ho tlosa lekoba:Sekoahelo sa siliconee ke ke ea senya foam e entsoeng ka katleho feela, empa hape e ka thibela haholo foam le ho thibela ho thehoa ha foam.Tšebeliso ea eona e nyane haholo, ha feela e eketsa karolo e le 'ngoe ho milione (1ppm) ea boima ba mochini o phoroselang, e ka hlahisa phello e senyang.Sebaka sa eona se sebelisoang hangata ke 1 ho isa ho 100 ppm.Hase feela litšenyehelo tse tlaase, empa hape ha li silafatse ntho e silafetseng.

Mefokolo eali-silicone defoamers:
a.Ho thata ho qhala Polysiloxane: Polysiloxane e thata ho qhibiliha ka metsing, e sitisang ho hasana ha eona tsamaisong ea metsi.Ho tlameha ho eketsoa moemeli oa ho qhalakanya.Haeba moemeli ea qhalakanyang a eketsoa, ​​emulsion e tla tsitsa 'me phello e senyang e tla fetoha.Ho futsanehile, hoa hlokahala ho sebelisa emulsifier e fokolang ho etsa hore phello ea defoaming e be ntle le emulsion e tsitsitseng.
b.Silicone e qhibiliha ka oli, e fokotsang phello ea eona ea ho senya tsamaiso ea oli.
c.Ho hanyetsa mocheso oa nako e telele le ho hanyetsa alkali e futsanehileng.
