V. Organic Silicon Antifoamer
Polydimethylsiloxane, eo hape e tsejoang e le oli ea silicone, ke karolo ea mantlha ea silicone defoamer.Ha ho bapisoa le metsi le oli e tloaelehileng, tsitsipano ea eona e ka holim'a metsi e nyenyane, e loketseng tsamaiso ea metsi e entsoeng ka metsi le tsamaiso ea oli e entsoeng ka mafura.Oli ea silicone e na le ts'ebetso e phahameng, ho qhibiliha ho tlase, thepa ea lik'hemik'hale e tsitsitseng, mefuta e mengata ea lisebelisoa tse khanyang, ho fokotseha ho fokolang, ho se chefo, le bokhoni bo hlaheletseng ba ho senya.Bothata ke ho se sebetse hantle ha foam inhibition.
1. Antifoamer e tiileng
Solid Antifoamer e na le litšobotsi tsa botsitso bo botle, ts'ebetso e bonolo, lipalangoang tse bonolo le tšebeliso e bonolo.E loketse karolo ea oli le karolo ea metsi, 'me mofuta oa ho hasana o mahareng o boetse o hlahelletse.E sebelisoa haholo tšimong ea foam e tlaase kapa e se nang foam e hlatsoang phofo.
2. Emulsion Antifoamer
Oli ea silicone ka emulsion defoamer e na le tsitsipano e kholo, 'me coefficient ea emulsification e kholo haholo.Hang ha emulsifier e khethiloe ka mokhoa o sa nepahaleng, e tla etsa hore sesebelisoa sa defoaming se behoe 'me se be le metamorphic ka nako e khutšoanyane.Ho tsitsa ha emulsion ho bohlokoa haholo ho boleng ba moemeli oa defoaming.Ka hona, ho lokisoa ha mofuta oa emulsion silicone defoamer ho lebisa tlhokomelo ho khetho ea emulsifier.Ka nako e ts'oanang, emulsion defoamer e na le tekanyo e kholo ka ho fetisisa ea silicone defoamer e nang le litšobotsi tsa theko e tlaase, sebaka se pharaletseng sa kopo, phello e hlakileng ea ho senya, joalo-joalo.Ka tsoelo-pele ea theknoloji ea tlhahiso, emulsion defoamer e tla ntlafala haholo.
3. Tharollo Antifoamer
Ke tharollo e entsoeng ka ho qhibiliha oli ea silicone ka har'a solvent.Molao-motheo oa eona oa ho senya ke hore likarolo tsa oli ea silicone li tsamaisoa ke solvent ebe li qhalakanngoa ka tharollo e phophomang.Ts'ebetsong ena, oli ea silicone e tla kopana butle-butle hore e be marotholi ho phethela ho senya.Oli ea silicone e qhibilihisitsoeng ka har'a sistimi e se nang metsi, joalo ka polychloroethane, toluene, joalo-joalo, e ka sebelisoa e le tharollo ea oli.
4. Antifoamer ea oli
Karolo e ka sehloohong ea oli ea defoamer ke oli ea dimethyl silicone.Oli e hloekileng ea silicone ea dimethyl ha e na phello e senyang 'me e hloka ho emulsified.Khohlano e kaholimo ea silicone e entsoeng ka emulsified e fokotseha ka potlako, 'me palo e nyane e ka fihlella ho phatloha ho matla le ho thibela lekoeba.Ha oli ea silicone e kopantsoe le karolo e itseng ea bathusi ba silica ba phekoloang ka hydrophobically, ho ka etsoa "defoamer ea motsoako oa oli."Silicon dioxide e sebelisoa e le ho tlatsa, hobane palo e kholo ea lihlopha tsa hydroxyl holim'a eona e ka ntlafatsa matla a ho qhalakanngoa ha oli ea silicone tsamaisong ea foaming, e eketsa botsitso ba emulsion, 'me ka ho hlakileng e ntlafatsa thepa ea defoaming ea silicone defoamer.
Hobane oli ea silicone e na le lipophilic, silicone defoamer e na le phello e ntle haholo ea ho senya motsoako oa tharollo e qhibilihang ka oli.Leha ho le joalo, lintlha tsena li lokela ho eloa hloko ha u sebelisa silicone defoamer:
● Silicone defoamer e tlaase ea viscosity e na le phello e ntle ea ho senya, empa ho phehella ha eona ho fokola;Silicone defoamer e phahameng ea viscosity e na le phello e liehang ea ho defoaming empa e phehella hantle.
● Haeba viscosity ea tharollo ea foam e tlaase, ho molemo ho khetha silicone defoamer e nang le viscosity e phahameng.Ho fapana le hoo, ha viscosity ea tharollo e phophomang e phahame, ho molemo ho khetha silicone defoamer e nang le viscosity e tlase.
● Boima ba molek'hule oa silicone defoamer e nang le oli e na le tšusumetso e itseng phello ea eona ea ho senya.
● Defoamer e nang le boima bo tlaase ba molek'hule e bonolo ho qhalakanya le ho qhibiliha, empa ho hloka mamello.Ho fapana le hoo, ts'ebetso ea defoamer e phahameng ea boima ba limolek'hule e fokola, 'me emulsification e thata, empa ho qhibiliha hoa fokola le ho tšoarella hantle.
