Li-defoaming agents tse sebelisoang ka tloaelo li ka aroloa ka silicon (resin), li-surfactants, alkane le oli ea diminerale ho latela likarolo tse fapaneng.
1, sehlopha sa silicon (resin).
Silicone defoaming agent e boetse e tsejoa e le emulsion type defoaming agent.Mokhoa oa tšebeliso ke ho emulsify silicone ka emulsifying agent (surfactant) le ho e hasanya ka metsing ebe o e kenya metsing a litšila.Silica powder ke mofuta o mong oa silicon defoamer e nang le phello e ntle ea ho senya.
2, sehlopha sa surfactant
Mofuta ona oa defoaming moemeli ke emulsifier ha e le hantle, sebelisa dispersive bohato ba holim'a sehlahiswa mafolofolo e leng, etsa lintho tse bonahalang tse foam boloka tsitsitseng emulsification boemo hasana ka metsing, qoba ho hlahisa foam ka tsela eo.
3. Liparafine
Parafine defoaming agent e entsoe ka boka ba parafine ea parafine kapa derivative ea eona e emulsified le ho qhalakanngoa ke emulsifying agent.Tšebeliso ea eona e tšoana le emulsified defoaming agent ea surfactant.
4. Oli ea diminerale
Oli ea liminerale ke eona defoamer e ka sehloohong.E le ho ntlafatsa phello, ka linako tse ling e kopantsoe le sesepa sa tšepe, oli ea silicone, silicon dioxide le lintho tse ling tse sebelisoang hammoho.Ho phaella moo, e le ho etsa hore oli ea diminerale e be bonolo ho hasana ka holim'a metsi a phophomang, kapa ho etsa sesepa sa tšepe ka mokhoa o tšoanang o qhalakantsoeng ka oli ea diminerale, ka linako tse ling e ka boela ea eketsa mefuta e sa tšoaneng ea li-surfactants.
Melemo le bofokoli ba mefuta e fapaneng ea li-agent tsa defoaming
Oli ea liminerale, amide, joala bo tlase, acid e mafura le ester e mafura, phosphate ester le lipatlisiso tse ling tsa organic defoaming agent le kopo ea pejana, ke ea moloko oa pele oa moemeli oa defoaming, o na le melemo ea ho fihlella habonolo lisebelisoa tse tala, ts'ebetso e phahameng ea tikoloho. , theko e tlaase ea tlhahiso;Bobebe bo lutse ka ts'ebetso e tlase ea defoaming, boits'oaro bo matla le maemo a thata a ts'ebeliso.
Polyether antifoaming agent ke moloko oa bobeli oa antifoaming agent, haholo-holo e kenyeletsang polyether ea ketane e otlolohileng, joala kapa ammonia e le ntho e qalang ea polyether, polyether derivatives e esterified ke terminal sehlopha sa boraro.Polyether defoaming agent ke molemo o moholo ka ho fetisisa oa bokhoni bo matla ba ho thibela foam, ho phaella moo, ho na le lisebelisoa tse ling tsa polyether defoaming tse nang le mocheso o phahameng oa ho hanyetsa, ho hanyetsa acid e matla le alkali le ts'ebetso e 'ngoe e babatsehang;Mefokolo e lekanyelitsoe ke mocheso, sebaka se moqotetsane sa ts'ebeliso, bokhoni bo fokolang ba ho tlosa lefome le sekhahla se tlase sa ho robeha ha bubble.
Silicone defoaming agent (moloko oa boraro oa defoaming agent) e na le ts'ebetso e matla ea ho foaming, bokhoni bo potlakileng ba ho fothola, ho se tsitse, ho se chefo tikolohong, ha ho na inertia ea 'mele, mefuta e mengata ea ts'ebeliso le melemo e meng, ka hona e na le menyetla e mengata ea ts'ebeliso le menyetla e mengata. bokhoni ba 'maraka, empa ts'ebetso ea anti-foaming e fokola.
Polyether modified polysiloxane defoaming agent e na le melemo ea polyether defoaming agent le silicone defoaming agent ka nako e le 'ngoe, e leng tataiso ea nts'etsopele ea moemeli oa ho senya.Ka linako tse ling e ka boela ea sebelisoa hape ho ea ka ho qhibiliha ha eona ho fapaneng, empa hajoale ho na le mefuta e fokolang ea li-agents tse joalo tsa defoaming, tse ntseng li le boemong ba lipatlisiso le nts'etsopele, 'me litšenyehelo tsa tlhahiso li holimo.
