Description

7713158-9 2 vilket medför en förhållandevis låg effektförbrukning. Behand- lingstemperaturen är ej kritisk och behöver ej överstiga rums- temperatur. Behandlingstiden är vid lämpligt vald strömtäthet kort. Alkalisulfamatet är, såvitt bekant, ogiftigt och Ofarligt. 7713158-9 2 which results in a relatively low power consumption. Treat- the temperature is not critical and need not exceed the room temperature temperature. The treatment time is at the appropriately selected current density short. The alkali sulphamate is, as far as is known, non-toxic and harmless.

Badet har lång livslängd. En sådan kombination av fördelar uppvisas ej av något känt rengöringssätt resp. -bad.The bath has a long life. Such a combination of benefits is not shown by any known cleaning method resp. -bad.

Företrädesvis arbetar man med en koncentration av omkring 100 g alkalisulfamat per liter badvätska och med en arbetsspänning av 10-15 V. Som anodmaterial användes lämpligen grafit. Alkalisulfamatet sönderdelas elektrolytiskt varvid alkalihydrbxid bildas vid katoden, åtföljd av en kraftig vätgas- utveckling. Detta har till följd att olja, fett och smuts av- lägsnas från varan. När strömmen brytes återbildas alkalisulfamat och olje- och fettföroreningarna frigöres och flyter upp till ytan av badet där de avskiljes med någon lämplig mekanisk metod, t.ex. filtrering. Elektrolyten förbrukas således inte, utan renas kontinuerligt mekaniskt. Metoden lämpar sig för de flesta metaller.Preferably you work with a concentration of about 100 g of alkali sulphamate per liter of bath liquid and with a operating voltage of 10-15 V. As anode material was suitably used graphite. The alkali sulphamate is electrolytically decomposed thereby alkali hydroxide is formed at the cathode, accompanied by a strong hydrogen development. As a result, oil, grease and dirt are removed. removed from the product. When the current is interrupted, alkali sulfamate is regenerated and the oil and fat contaminants are released and float up to the surface of the bath where they are separated by any suitable mechanical method, for example filtration. The electrolyte is thus not consumed, but continuously mechanically cleaned. The method is suitable for most people metals.
