Muindasitiri, kana dambudziko refuro rikasatora nzira chaiyo, zvichave zvakaoma kugadzirisa, saka unogona kuedzamushonga wekubvisa furoPakubvisa hunhu hweganda, hazvisi nyore chete kuti basa racho riitwe, asiwo mhedzisiro yacho inooneka. Tevere, ngatinyatsoongorora zvakadzamaZvishandiso zveSilicone Defoamingkuti uone kuti zvinhu zvakawanda sei zvawakanganwa.
Munguva yekugadzira nekushandisa machira, matambudziko efuro anowanzoitika. Kana masheya akasabviswa nenguva, kuyerera kwejira racho kuchakanganiswa, zvichikonzera zvikanganiso pamusoro, kusaenzana, uye kutsemuka panguva yekuumbwa kwefirimu, izvo zvinozopedzisira zvaita kuti mari yekugadzira iwedzere. , saka tinofanira kushandisa nzira isingadhuri kugadzirisa dambudziko iri kuti tidzorere kurasikirwa kwacho.
Kune mhando dzakawanda dzema defoamers, anosanganisira mineral oil, silicone, uye polyether, nezvimwewo, izvo zvine zvakanakira zvakawanda zvakaita sekuzvigadzira, kupararira kuri nyore, kushandiswa kwakasimba, kubvisa furo zvakanaka, uye kudzvinyirira furo kwenguva refu. Zvose pamwe chete, hazvizokanganisi hunhu hwekugadzira firimu mushure mekushandisa, uye hazvizokonzere zvikanganiso pamusoro pependi, kunyanya kune masisitimu ependi anobva mumvura.
Huwandu hwemushonga wekubvisa manyoka hushoma kwazvo, chikamu chimwe chete kusvika zvitatu zvezviuru chete ndizvo zvinogona kuita kuti tsvina ibude pachena, saka inoshandiswa zvakanyanya mukugadzira machira akavakirwa mumvura, inki, inki, varnish, mafuta emupendero weganda, kugadzira mapepa, kuputira, guruu relaminating, pendi yelatex, manamira nezvimwe zvinhu.
Parizvino, padambudziko refuro, nzira nhatu dzinotevera dzinowanzo shandiswa pakubvisa furo.
1. Nzira yekuchenesa ganda nekushandisa michina
Kubvisa furo mumichina kunowanzo shandiswa mumamiriro ezvinhu apo kupisa kunodiwa kuti chigadzirwa chiparare uye kupatsanurwa kwefuro, zvakaita sekuchinja kwekumanikidzwa nekukurumidza, kupatsanurwa kwemvura nefuro mucentrifugal, kupfapfaidza masisitimu efuro nemhepo yakamanikidzwa, kupfapfaidza kwe ultrasonic, nezvimwewo.
2. Nzira yekubvisa tsvina mumuviri
Kazhinji, kubvisa furo mumuviri kunonyanya kushandisa nzira yekushandura tembiricha kuita furo uye kudzvinyirira furo. Sezvo tembiricha ichiwedzera, viscosity yemushonga inoderera uye solvent inonyangarika, zvichiita kuti furo riputsike. Kana tembiricha yadzikira, kusimba kwepamusoro kwefuro kunoderera, uye tembiricha yakaderera inokonzera icing, iyo inokanganisa chimiro chefuro uye inoita kuti furo riputsike.
3. Nzira yekubvisa manyoka nemakemikari
Nzira yekubvisa mabhakitiriya inotsamira zvakanyanya pakuwedzerwa kwesilicone defoaming agent, inova nzira iri nyore uye inoshanda yekubvisa mabhakitiriya uye antifoaming pakati penzira nhatu idzi. Inonyanya kutsamira pakuchinja pH value, kuisa munyu, uye kuchinja maitiro emakemikari efuro. Nheyo ndeyekuti mushure mekunge mushonga wekubvisa mabhakitiriya wawedzerwa kumushonga wekubvisa mabhakitiriya, mamorekuru ekubvisa mabhakitiriya achaparadzirwa zvisina kurongeka pamusoro pemvura, opararira nekukurumidza, uye ogadzira firimu rakatetepa rine mativi maviri, iro richapararira, kupinda, uye kupinda muzvikamu, zvishoma nezvishoma dzorera madziro matete efuro rekutanga, dzivisa kuumbwa kwefirimu re elastic, kuparadza kugona kweforo kuzviporesa, uye kuita kuti furo riputike.
Zvichienderana nemamiriro akasiyana uye zvinodiwa zvakasiyana zvekubvisa madota, sarudza nzira yekubvisa madota uye mushonga wekubvisa madota unokukodzera. Tinogona kukupa mushonga wekubvisa madota wakakodzera iwe, tinokugamuchira kutenga.
