1 Kusanyungudika kana kusanyungudika zvakanaka mumvura iri furo zvinoreva furo rakatyoka, uyedefoamerinofanira kuiswa uye kuisa pfungwa pafirimu yefoam. Kune iyo defoamer, inofanira kunge yakanyanyisa uye yakasimbiswa pakarepo, uye nokuda kweiyo defoamer, inofanira kugara ichichengetwa mumamiriro ezvinhu aya.
Naizvozvo, defoamer iri mune supersaturated state mumvura inopupuma, uye zviri nyore kusvika kune supersaturated state chete kana isinganyungudika kana kusanyungudika zvisina kunaka. Isinganyungudika kana kuti isina kunyungudika, zviri nyore kuunganidza pane gasi-mvura yemvura interface, zviri nyore kuisa pfungwa pane iyo foam firimu, uye inogona kuita basa pane yakaderera. Kune ma defoam anoshandiswa mumasisitimu emvura, mamorekuru ezvishandiso zvinoshanda anofanirwa kunge aine hydrophobic uye asina simba hydrophilic, uye kukosha kweHLB kunofanirwa kunge kuri muhuwandu hwe1.5-3 kushanda zvakanyanya.
2 Kupokana kwepamusoro kwakadzikira pane kwemvura inopupuma. Chete kana iyo intermolecular simba re defoamer iri diki uye tension yepasi yakadzikira pane iyo yemvura inopupuma, iyo defoamer particles inogona kunyudzwa uye kuwedzera pafuro firimu. Izvo zvakakosha kuti ticherechedze kuti kudhonzerana kwepamusoro pemvura inopupuma hakusi iko kukakavara kwepamusoro kwemushonga, asi kunetsana kwepamusoro kwemushonga unopupuma.
3. Imwe dhigirii yehukama nemvura inopupuma. Sezvo maitiro ekubvisa furo ari chaizvo makwikwi pakati pekumhanya kwekuputsika kwefuro uye nekumhanya kwekugadzira furo, defoamer inofanirwa kukwanisa kupararira nekukasira mumvura inopupuma kuitira kuti ikurumidze kuita basa mukuwanda kwemvura inopupuma. Kuita kuti defoamer ipararire nekukurumidza, izvo zvinoshanda zve defoamer zvinofanirwa kuve nehumwe dhigirii rehukama nemvura inopupuma. Kana iyo inoshandiswa inoshandiswa ye defoamer iri pedyo zvakanyanya nemvura inoputika, inonyunguduka; kana dziri kure, dzichanetsa kupararira. Chete kana hukama hwakakodzera, mhedzisiro ichava yakanaka.
4. Hapana makemikari anoita nemvura inopupuma. Defoamer inopindirana nemvura inopupuma. Kune rumwe rutivi, defoamer icharasikirwa nemigumisiro yayo, uye kune rumwe rutivi, zvinhu zvinokuvadza zvinogona kugadzirwa, zvinokanganisa kukura kwe microorganisms.
5. Low volatility uye nguva yakareba yekuita. Kutanga, sarudza nzira iyo defoamer inoda kushandiswa, ingave iri mvura-based system kana mafuta-based system. Semuenzaniso, muindasitiri yekuvirisa, mafuta-based defoamers akadaipolyether-modified silicone kana polyether inofanira kushandiswa. Mvura-based coating industry inofanira kushandisa mvura-based defoamers uye silicone defoamers. Sarudza defoamer, enzanisa kuwanda kwekuwedzera, uye tarisa kumutengo kuti uwane yakanyanya kukodzera uye ine hupfumi defoamer chigadzirwa.

Ichi chinyorwa nderekureva uye kutaurirana chete uye chinogona kusashandiswa kuita zvekutengesa. Kodzero ndeyemunyori wekutanga. Kana pane kukanganisa, tapota taura nesu kuti tibvise.
