Skumavskiljare<\/h1>\n

Skumhantering \u00e4r en viktig aspekt av ytbehandlingens effektivitet, men det kan vara sv\u00e5rt att v\u00e4lja ett effektivt skumd\u00e4mpningsmedel f\u00f6r vissa applikationer.<\/p>\n

Fluorsilikonolja kombinerades med en skumd\u00e4mpare av akrylsampolymer (ACD), pentanon och l\u00f6sningsmedelsolja f\u00f6r f\u00e4rg (kvalificerad produkt nr 200) i proportionerna 2%, 8% och 25% med antingen mekanisk eller artificiell omr\u00f6rning f\u00f6r att skapa en skumd\u00e4mpande f\u00f6rening.<\/p>\n

Avskumningsmedel<\/h2>\n

Avskumningsmedel anv\u00e4nds f\u00f6r att l\u00f6sa upp skumbubblor genom att s\u00e4nka yt- och gr\u00e4nssnittssp\u00e4nningen och kan finnas i flytande form, pulverform eller emulsionsform. De anv\u00e4nds ofta i m\u00e5nga olika till\u00e4mpningar, t.ex. f\u00e4rg och ytbel\u00e4ggningar f\u00f6r att f\u00f6rhindra groph\u00e5l, papperstillverkning f\u00f6r effektiv bearbetning, oljeborrning, reningsverk f\u00f6r avloppsvatten samt f\u00e4rgborttagnings- och reng\u00f6ringsmedel.<\/p>\n

Flytande skumd\u00e4mpare anv\u00e4nder mineraler, vegetabiliska oljor och vaxer som flytande skumd\u00e4mpare f\u00f6r att s\u00e4nka ytsp\u00e4nningen. Polydimetylsiloxan - vanligen kallat dimetikon - \u00e4r en s\u00e4rskilt kraftfull skumd\u00e4mpare som tillverkas av material av silikontyp; dessa skumd\u00e4mpare fungerar ocks\u00e5 som effektiva s\u00e4ttningsh\u00e4mmare och reologikontrollanter.<\/p>\n

Skumd\u00e4mpare i pulverform anv\u00e4nder hydrofoba kiseldioxidpartiklar och andra fina fasta partiklar f\u00f6r att l\u00f6sa upp skumbubblor vid olika temperaturer, vilket ger effektiva skumd\u00e4mpare f\u00f6r olika situationer.<\/p>\n

Emulsionsbaserade skumd\u00e4mpare anv\u00e4nder polyeten, fettalkoholer eller andra ytaktiva \u00e4mnen f\u00f6r att dispergera v\u00e4tskor som de har blandat ihop till dispersionsl\u00f6sningar. Dessa skumd\u00e4mpare \u00e4r idealiska f\u00f6r vattenbaserade system.<\/p>\n

Skumd\u00e4mpande medel<\/h2>\n

Skumbrytare best\u00e5r vanligtvis av hydrofoba \u00e4mnen som \u00e4r dispergerade i en v\u00e4tska f\u00f6r att orsaka bristning av bubbelfilmer och minska ytsp\u00e4nningen, vilket g\u00f6r att bubblorna bryts l\u00e4ttare.<\/p>\n

Silikonskumd\u00e4mpare \u00e4r det sj\u00e4lvklara valet n\u00e4r det g\u00e4ller skumd\u00e4mpare och hj\u00e4lper till att f\u00f6rb\u00e4ttra produktionseffektiviteten och produktkvaliteten genom att minska avfallet, g\u00f6ra processerna effektivare och \u00f6ka blandningseffektiviteten.<\/p>\n

Avskumningsmedel kan ocks\u00e5 skydda sm\u00f6rjmedel fr\u00e5n korrosion och samtidigt f\u00f6rb\u00e4ttra deras stabilitet och h\u00e5llbarhet. Det finns olika typer av skumd\u00e4mpare, inklusive silikon-, icke-silikon- och polyeterskumd\u00e4mpare som var och en erbjuder sin egen specifika till\u00e4mpning; en s\u00e5dan sammansatt skumd\u00e4mpare inneh\u00e5ller silikonskumd\u00e4mpare med icke-flyktig icke-silikon icke-flyktig olja f\u00f6r slitageskyddande hydrauloljor med h\u00f6ga skumningskrav - idealisk f\u00f6r slitageskyddande hydrauloljor med luftutsl\u00e4ppsegenskaper; utm\u00e4rkt skumningsprestanda samtidigt som den erbjuder liten f\u00f6rbrukning l\u00e5g volatilitet och f\u00f6rb\u00e4ttrad lagringsstabilitet f\u00f6r anv\u00e4ndning i slitageskyddande hydrauloljor med h\u00f6ga skumningskrav j\u00e4mf\u00f6rt med deras motsvarigheter.<\/p>\n

Uppl\u00f6sande medel<\/h2>\n

Masterbatch med skummedel \u00e4r en integrerad komponent i l\u00e4ttviktsplaster som f\u00f6rb\u00e4ttrar prestanda och anv\u00e4ndbarhet och hj\u00e4lper tillverkare att minska produktdensiteten utan att \u00e4ventyra viktiga egenskaper som strukturell integritet eller h\u00e5llbarhet. Som ett resultat kan f\u00f6retagen s\u00e4nka fraktkostnaderna avsev\u00e4rt samtidigt som de f\u00f6rb\u00e4ttrar bearbetningshastigheterna och minimerar materialanv\u00e4ndningen.<\/p>\n

Skumd\u00e4mpare och skumd\u00e4mpare verkar genom att h\u00e4mma skumbildningen och l\u00f6sa upp befintliga bubblor, vilket effektivt undertrycker skumbildningen. De m\u00e5ste administreras i r\u00e4tt koncentration; f\u00f6r mycket kan destabilisera en sprutl\u00f6sning medan f\u00f6r lite inte alls d\u00e4mpar skumbildningen.<\/p>\n

Skumd\u00e4mpare best\u00e5r vanligtvis av nonjontensider, silikontensider eller v\u00e4xtoljekoncentrat. N\u00e4r de appliceras p\u00e5 ytor bryter de upp vattendroppar i luften s\u00e5 att de sprids j\u00e4mnt och snabbt. Andra vanliga skumbildare \u00e4r \u00e4ggvita, vassleproteiner och spansproteiner, tensider som minskar ytsp\u00e4nningen mellan bubblorna och fuktighetsbevarande medel som hj\u00e4lper till att h\u00e5lla kvar fukten.<\/p>","protected":false},"excerpt":{"rendered":"
