Silicone Antifoam ke eng

Li-antifoam tsa silicone hangata li entsoe ka silika ea hydrophobized e hasaneng hantle ka har'a mokelikeli oa silicone.Motsoako o hlahisoang ka nako eo o tsitsisoa ka emulsion e thehiloeng metsing kapa ka oli.Li-antifoam tsena li sebetsa haholo ka lebaka la ho se sebetse ha lik'hemik'hale ka kakaretso, potency esita le maemong a tlaase, le bokhoni ba ho hasana holim'a filimi ea foam.Haeba ho hlokahala, li ka kopanngoa le lintho tse ling tse thata tsa hydrophobic le lino ho ntlafatsa thepa ea tsona ea ho senya.

Hangata ho khethoa li-antifoam tsa silicone.Ba sebetsa ka ho theola tsitsipano e holim'a metsi le ho senya li-bubble tsa foam, e leng se lebisang ho putlama ha bona.Ketso ena e thusa ho felisa ka potlako foam e teng hape e thusa ho thibela ho thehoa ha foam.

Melemo ea silicone defoamer

• 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 li-hydrocarbon kapa lintho tse phelang tse nang le lihlopha tsa hydrocarbon.Kaha oli ea silicone ha e qhibilihe linthong tse ngata, silicone defoamer e na le mefuta e mengata ea lisebelisoa.E ka sebelisoa eseng feela bakeng sa lits'ebetso tsa metsi a defoaming, empa hape le bakeng sa lits'ebetso tsa oli tsa defoaming.

• Khatello e tlaase holim'a metsi

Khatello e kaholimo ea oli ea silicone hangata ke 20-21 dynes / cm mme e nyane ho feta tsitsipano ea metsi (72 dynes / cm) le maro a akaretsang a foam, a ntlafatsang phello ea taolo ea foam.

• Botsitso bo botle ba mocheso

Ho nka oli ea silicone ea dimethyl e sebelisoang ka tloaelo e le mohlala, ho hanyetsa mocheso oa nako e telele ho ka fihla ho 150 ° C, 'me ho hanyetsa mocheso oa nako e khutšoanyane ho ka fihla ho feta 300 ° C, ho netefatsa hore li-silicone defoaming agents li ka sebelisoa ka mocheso o pharaletseng.

• Botsitso bo botle ba lik'hemik'hale

Oli ea silicone e na le botsitso bo phahameng ba lik'hemik'hale 'me ho thata ho itšoara ka lik'hemik'hale ka lintho tse ling.Ka hona, hafeela tokiso e le e utloahalang, li-silicone defoaming agents li lumelloa ho sebelisoa mekhoeng e nang le li-acids, alkalis le letsoai.

• Inertia ea 'mele

Oli ea silicone e ipakile e se chefo ho batho le liphoofolo.Ka hona, li-silicone defoamers (tse nang le li-emulsifiers tse se nang chefo tse loketseng, joalo-joalo) li ka sebelisoa ka mokhoa o sireletsehileng ka har'a makhasi le pampiri, ho sebetsana le lijo, lik'hamphani tsa bongaka, tsa meriana le tsa litlolo.

• Ho tlosa lekoba ho matla

Li-silicone defoamers ha li khone feela ho senya foam e sa batleheng ka katleho, empa hape li thibela haholo foam le ho thibela ho thehoa ha foam.Tekanyetso e nyane haholo, 'me ke karolo e le' ngoe feela ea milione (1 ppm kapa 1 g/m3) ea boima ba mochini o phophomang o ka eketsoang ho hlahisa phello e senyang.Mofuta oa eona o tloaelehileng ke 1 ho isa ho 100 ppm.Hase feela litšenyehelo tse tlaase, empa e ke ke ea silafatsa thepa e ntseng e silafatsoa.

Li-antifoam tsa silicone li nkoa e le tsa bohlokoa bakeng sa botsitso ba tsona, ho lumellana le lintho tse fapa-fapaneng, le katleho ea maemo a tlaase.Leha ho le joalo, ho bohlokoa ho etsa bonnete ba hore li lumellana le litekanyetso tsa taolo 'me li loketse ts'ebeliso e khethehileng ho qoba litlamorao life kapa life tse mpe boleng ba sehlahisoa kapa tikoloho.
