1 insoluble kana isina kunyatso nyura mumvura inopenya zvinoreva kuti foam yaputswa, uyedefoamerinofanirwa kuve yakaomeswa uye yakaiswa pamhepo foam firimu. Kune defoamer, inofanira kunge yakaomeswa uye yakamanikidzwa pakarepo, uye yeiyo defoamer, inofanira kugara ichichengetwa mune ino mamiriro.
Naizvozvo, defoamer iri mumamiriro akapusa mumvura inopenya, uye zviri nyore kuti usvike kune yakashongedzwa mamiriro chete kana ichisvika kana isinganyanyoka. Insoluble kana isina kunyatso nyura, zviri nyore kuunganidza pagesi-yemvura interface, zviri nyore kuisa pfungwa pane firimu remukati, uye unogona kutamba chiitiko pane yakaderera constontration. Kune defoamers inoshandiswa mune zvemvura masisitimu, mamorekuru ezvematongerwo enyika anofanirwa kunge ane hydrophobic uye asina kusimba hydrophilic, uye kukosha kweHLB kunofanirwa kunge kuri mune iyo 1.5-3 yekushanda zvakanyanya.
2 Iyo nzvimbo yekunetsana yakaderera pane iyo yemvura inopenya. Chete kana chisimba chinonhuwirira che defoamer chidiki uye chinetso chechiso chakaderera pane icho chemvura inopenya, iyo denderedzwa ranyudzwa uye yakawedzera paFoam firimu. Izvo zvakakosha kucherechedza kuti kushushikana kwepasi kwemvura inopupurira haisi iyo yekunetsana yemhinduro, asi iyo nzvimbo yekunetsana yemhinduro yekupupuma.
3 Sezvo maitiro okusazvibata ari mukwikwidzi pakati pekumhanya kwemugungwa uye kumhanya kwechizvarwa chechizvarwa, iyo defoamer inofanira kukwanisa kupararira nekukurumidza mumvura inopera kuti iite basa rakaputika mumvura inopenya. Kuita kuti defoamer difise nekukurumidza, izvo zvinoshanda zvinongedzo zve defoamer chinofanira kuve neyakaenzana nehuwandu hwehudyu. Kana izvo zvinoshandiswa zvinoshanda zve defoamer zviri padyo nemvura inopenya, ivo vachanyungudika; Kana ivo vari kure zvakanyanya, ivo vachange vakaoma kupararira. Chete kana kusanzwisisika kwakakodzera, mhedzisiro ichave yakanaka.
4 Iyo defoamer inoshanda nemvura inopenya. Kune rimwe divi, defoameri acharasikirwa nemhedzisiro yake, uye kune rumwe rutivi, zvinhu zvinokuvadza zvinogona kugadzirwa, zvichikanganisa kukura kwehutachiona.
5. Kuderera kushoma uye kwenguva yakareba chiitiko. Kutanga, sarudza iyo system iyo iyo defoamer inofanirwa kushandiswa, ingave iri nzira-yakavakirwa mvura kana iyo yemafuta-yakavakirwa system. Semuenzaniso, muindasitiri yemafuta, ine mafuta-yakavakirwa defoamers yakadai sepolyether-yakagadziridzwa silicone kana polyether inofanira kushandiswa. Indasitiri yemvura inovhara yemvura inofanira kushandisa madhimoni emvura uye akasarudzika silicone defoamers. Sarudza iyo defoamer, enzanisa iyo yekuwedzera mari, uye tarisa kumutengo kuti uwane iyo yakakodzera uye yehupfumi defoamer chigadzirwa.
