V. Organic silicon antifoamer
Polydimetsietsiloxane, anozivikanwawo seyefuta silicone, ndiyo chinhu chikuru cheSilicone defoamer. Kuenzaniswa nemvura uye nemafuta akajairika, kushushikana kwayo kwakakwana, uko kwakakodzera kune ese emvura-yakavakirwa mvura-yekupenga system uye yemafuta-based foaming system. Silicone mafuta ane basa rakakwirira, rakaderera solubility, rakagadzikana makemikari zvivakwa, Chiedza chekushandisa manhamba, yakaderera kushamisika, isina-chepfu, uye yakakurumbira yekudzora kugona. Iko kusanzwisisika kune murombo foam inhibition basa.
1. Solid antifoamer
Solid antifoamer ane hunhu hwekugadzikana kwakanaka, maitiro akapusa, ekufambisa nyore uye kushandiswa nyore. Izvo zvakakodzera kune ese echikamu cheoiri uye chikamu chemvura, uye yemhando yekuparadzira yemhando yakakurumbira. Iyo inoshandiswa zvakanyanya mumunda weiyo yakaderera foam kana isiri foam yekugeza poda.
2. Emulsion Antifoamer
Mafuta eSilicone ari mu emulsion defoamer ane kukakavara kukuru, uye exustomication coefficient yakanyanya. Kana emulsifier yakasarudzwa isina kudzivirirwa, inokonzeresa mumiririri kuti adzorerwe uye metamorphic munguva pfupi. Iko kusimba kwemelsion kwakanyanya kutsoropodza kunaka kwehunhu hwekutsamwisa mumiririri. Naizvozvo, kugadzirira kwe emulsion Type Silicone defoamer inotarisa pane sarudzo ye emulsifier. Panguva imwecheteyo, emulsion defoamer ine madhiri makuru muSilicone defoamer nehunhu hwemutengo wakaderera, chiitiko chakajeka, uye zvichingoitika. Nekufambira mberi kwehunyanzvi hwekuumbwa, emulsion defoamer anokura zvakanyanya.
3. SCORICO diaTIFOAMER
Iwo mhinduro yakaitwa nekunyungudika silicone mafuta muSolvent. Nheyo dzayo dzinodzvinyirira ndeiyi silicone mafuta zvikamu zvinotakurwa nemafuta uye akapararira mumhinduro yekupupuma. Muchiitiko ichi, mafuta essillone achakurumidza kuita madonhwe kuti apedze kuderera. Silicone mafuta akanyungudutswa mune isiri-yemukati orgic Solution Solution system, yakadai polychloroethane, toluene, etc., inogona kushandiswa semhinduro yemafuta.
4. Oiri antifoamer
Chikamu chikuru chemafuta defoamer ndeye dimethyl silicone mafuta. Yakachena Dimethyl Silicone Oiri haina maitiro ekutsemuka uye inoda kuvezwa. Nzvimbo yekunetsana yekukasira kwekupembera silicone inodzora nekukurumidza, uye mari shoma inogona kuwana yakasimba foam kutyora uye inhibition. Kana mafuta eSildone akasanganiswa aine imwe chikamu chehydrophobically vaibata Silika vabatsiri, mafuta akaomarara defoamer anogona kuumbwa. Silicon Dioxide inoshandiswa semuridzi wehydroxyl mapoka ari pamusoro penzvimbo yayo inogona kuwedzera simba reSildion, wedzera kugadzikana kweiyo emulsion, uye zviri pachena kuvandudza nzvimbo yekudzvinyirira yeiyo silicone defoamer.
Nekuti silicone mafuta ari lipeilic, silicone defoamer ine yakanaka kwazvo yekudzora mhedzisiro pane yekunyaradza mafuta. Nekudaro, idzi pfungwa dzinofanira kutariswa kana dzichishandisa silicone defoamer:
● Kuderera viscosity silicone defoamer kune tsika yakanaka kwazvo, asi kutsungirira kwayo kwakashata; Yakakwira viscosity silicone defoamer inononoka kutsungirira maitiro asi kutsungirira kwakanaka.
● Kana vhiza yemhinduro yekupembera iri pasi, zviri nani kusarudza iyo silicone defoamer ine yakakwira viscosity. Kusiyana neizvozvo, iyo yepamusoro vhiza yemhinduro yekupikisa ndeyekuti, zvirinani kusarudza iyo silicone defoamer ine kuderera viscosity.
● Kurema kwemanyorerwe kwe oiri silicone defoamer kune imwe pesvedzero pane yayo denderedzwa maitiro.
● Iyo defoamer ine huremu hwakaderera nyore kurerutsa nekunyungudika, asi kushaikwa kwekushingirira. Kusiyana neizvozvo, kuita kwekusazvibata kwehuremu hwakanyanya hwemuti defoamer murombo, uye kusimbiswa kwakaoma, asi iyo solubility murombo uye kusimba kwakanaka.
