Kune marudzi akawanda eDefoamersuye dzinoshandiswa zvakanyanya.Iyo nzira ye "kudzvinyirira furo" uye "kuputsika kwefuro" ye defoamer ndeiyi: kana defoamer yawedzerwa kune sisitimu, mamorekuru ayo anogovaniswa zvisina tsarukano pamusoro pemvura, achidzivirira kuumbwa kweiyo elastic firimu, ndiko kuti, kugumisa. chizvarwa chefuro.Kana iyo sisitimu ichiburitsa huwandu hukuru hwefuro, wedzera defoamer, mamorekuru ayo anobva apararira pamusoro pefuro, anopararira nekukurumidza, ogadzira yakaonda yakapetwa kaviri firimu layer, inowedzera kupararira, kupinda, uye kupinda muzvikamu, nokudaro kutsiva madziro akatetepa. yepakutanga foam film.Nekuda kwekudzikama kwayo kwepasi, inoyerera ichienda kumvura ine kusimba kwepamusoro-soro iyo inoburitsa furo, kuitira kuti mamorekuru e defoamer ane kuderera kwepasi tension arambe achipararira uye kupinda pakati peiyo gasi-mvura yemvura interface, zvichiita kuti firimu riite kutetepa nekukurumidza, uye furo rinokanganiswawo nepamusoro pepamusoro.Iyo firimu yefirimu ine tension yakakwirira inokwevera zvakasimba, kuitira kuti kushungurudzika kwakakomberedza furo kusingaenzaniswi, izvo zvinotungamirira ku "foam breaking".Iyo defoamer molecules iyo isingagadziriswi muhurongwa ichapindazve pamusoro peimwe firimu yefuro, uye zvichingodaro, furo rose richaparadzwa zvachose.
Nzira yekusarudza yakaruramaAntifoam
Kugadzirwa uye kuvakwa kwejasi kunoburitsa mabubbles kune akasiyana madhigirii.Chizvarwa chebhubhu chinotadzisa kufambira mberi kwakanaka kwekugadzira uye kuvaka, uye panguva imwechete kunounza kukanganisa kune yakapedzwa coating film.Sarudzo chaiyo yeakakodzera defoamer inogona kuve nechokwadi kufambira mberi kwakajairwa kwekugadzira uye kuvaka.
Basa re defoamer: paradza firimu remvura pamusoro pevhu, kudzivirira kuumbwa kwebubble uye kukurudzira kuparara kwebubble.Iyo defoamer inoshandiswa kune mabhuru mahombe, uye iyo microfoam inoda kushandiswa pamwe chete nekubvisa uye kubvisa furo.
Defoamer maficha: Iyo defoamer haina kunyungudika mukati, asi inogona kupinda nekupararira mukati meiyo microdroplets.Iyo yakanyanya kushanda dhayamita ye defoamer microdroplets yakaenzana nehupamhi hwemadziro efoam.
Defoamer kuumbwa:Defoamersnokuda kwemvura-based architectural coatings yakakamurwa kuva isiri-silicon uye silicon-ine marudzi.ConventionalDefoamersinoumbwa nezvikamu zvinotevera:
Active substance: Inoita senge inopwanya furo uye inobvisa furo ine kuderera kwepasi.Vamiriri vanosanganisira mafuta emhuka nemiriwo, hydrophobic silica, madoro akakwira, nezvimwe.
Diffusion agent: Wetting emulsifier kuti ive nechokwadi chekuti defoaming micro-droplets inopararira uye kubata bhaisikopo rebubble nekupararira.Kune asiri (octyl) phenol polyoxyethylene ether, sipo munyu uye zvichingodaro.
Mutakuri: Inobatsira chinhu chinoshanda kuti chisanganise nefoaming system, uye zviri nyore kupararira mufoaming system.Kubatanidza izvo zviviri, ine kuderera kwepasi tension, inobatsira kudzvanya furo, uye inogona kuderedza mitengo.
Mamiriro maviri anofanirwa kusangana pakusvibisa: kupinza chinhu: E=γ1+γ12-γ3 > 0, kuve nechokwadi chekuti defoamer inopinda mumadziro efuro;spreading factor S=γ1-v12-γ3 >0, kuona kuti defoamer droplets Diffusion inopararira mufoam media.
