V. Organic Silicon Antifoamer
Polydimethylsiloxane, inozivikanwawo sesilicone mafuta, ndiyo chikamu chikuru chesilicone defoamer.Kana ichienzaniswa nemvura uye nemafuta akajairika, kushushikana kwayo kwepamusoro kudiki, kwakakodzera kune ese mvura-based foaming system uye oiri-based foaming system.Oiri yeSilicone ine yakakwira chiitiko, yakaderera solubility, yakagadzika makemikari zvivakwa, chiedza chekushandisa renji, kuderera kuderera, kusiri muchetura, uye kwakakurumbira defoaming kugona.Izvo zvisingabatsiri ndezvakashata foam inhibition performance.
1. Solid Antifoamer
Solid Antifoamer ine hunhu hwekugadzikana kwakanaka, maitiro ari nyore, kufambisa kuri nyore uye kushandisa nyore.Inokodzera ese eiri chikamu chemafuta uye chikamu chemvura, uye yepakati dispersion mhando zvakare yakakurumbira.Inoshandiswa zvakanyanya mumunda wefoam yakaderera kana isina furo yekugeza poda.
2. Emulsion Antifoamer
Iyo silicone oiri mu emulsion defoamer ine tension yakakura, uye emulsification coefficient yakakura kwazvo.Kana iyo emulsifier yasarudzwa zvisina kunaka, ichaita kuti defoaming agent igadzirwe uye metamorphic munguva pfupi.Kugadzikana kwe emulsion kunonyanya kukosha kumhando ye defoaming agent.Nokudaro, kugadzirira emulsion type silicone defoamer inotarisa pakusarudza emulsifier.Panguva imwecheteyo, iyo emulsion defoamer ine yakakura dosage musilicone defoamer ine hunhu hwemutengo wakaderera, yakakura application scope, yakajeka defoaming mhedzisiro, zvichingodaro.Nekufambira mberi kwehunyanzvi hwekugadzira, emulsion defoamer inokura zvakanyanya.
3. Solution Antifoamer
Iyo mhinduro yakagadzirwa nekunyungudutsa silicone mafuta mu solvent.Yayo defoaming musimboti ndeyekuti silicone oiri zvikamu zvinotakurwa nezvinonyungudutsa uye zvakaparadzirwa mufuro mhinduro.Mukuita uku, mafuta esilicone anozonyura kuita madonhwe kuti apedze kuburitsa furo.Silicone oiri yakanyungudutswa mune isiri-aqueous organic solution system, senge polychloroethane, toluene, nezvimwewo, inogona kushandiswa seoiri mhinduro defoaming.
4. Mafuta Antifoamer
Chinhu chikuru chemafuta defoamer dimethyl silicone oiri.Yakachena dimethyl silicone mafuta haina defoaming mhedzisiro uye inoda emulsified.Iko kushushikana kwepamusoro kwe emulsified silicone inodzikira nekukurumidza, uye shoma inogona kuwana yakasimba kuputswa kwefuro uye inhibition.Kana mafuta esilicone akasanganiswa neimwe chikamu chehydrophobically kurapwa silica vabatsiri, mafuta emusanganiswa defoamer anogona kuumbwa.Silicon dioxide inoshandiswa sekuzadza, nokuti yakawanda yemapoka e-hydroxyl pamusoro payo inogona kuwedzera simba rekuparadzira resilicone mafuta mumhepo inoputika, kuwedzera kugadzikana kwe emulsion, uye zviri pachena kuti inovandudza pfuma yakasvibiswa yesilicone defoamer.
Nekuti mafuta esilicone ane lipophilic, silicone defoamer ine yakanakisa defoaming mhedzisiro paoiri-soluble solution.Nekudaro, aya mapoinzi anofanirwa kutariswa kana uchishandisa silicone defoamer:
● Low viscosity silicone defoamer ine yakanaka defoaming effect, asi kupfuurira kwayo kwakashata;Yakakwira viscosity silicone defoamer ine inononoka defoaming mhedzisiro asi yakanaka kushingirira.
● Kana iyo viscosity yemushonga unoputika yakaderera, zviri nani kusarudza silicone defoamer ine viscosity yakakwirira.Pane zvinopesana, iyo yakakwira viscosity yemushonga unopupuma, zviri nani kusarudza iyo silicone defoamer ine yakaderera viscosity.
● Huremu hwehuremu hweoiri silicone defoamer hune zvimwe zvinokanganisa pakubvisa furo.
● Iyo defoamer ine yakaderera molecular uremu iri nyore kuparadzira uye kunyungudika, asi kushaikwa kwekutsungirira.Pane zvinopesana, iyo yekubvisa furo kweyakakwira molecular uremu defoamer haina kunaka, uye emulsification yakaoma, asi solubility haina kunaka uye kusimba kwayo kwakanaka.
