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, ho hloka botsitso, ho se chefo, le bokhoni bo hlahelletseng 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 ho 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 moemeli oa defoaming a behoe 'me a 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 le ho 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. Khatello e kaholimo ea silicone ea 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, ea 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 tlosa lefome ho 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 fosahetse; 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 ea oli ea silicone defoamer 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 haelloa ke ho phehella. 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.
