Description
Technical field
The present invention relates to chemical field, particularly relate to a kind of air conditioner aluminium foil surface passivation liquid.
Background technology
Aluminum is that nature stores one of the abundantest metallic element, owing to aluminum and alloy thereof have little, good the leading of proportion
Heat and electric conductivity, reflective is strong, be prone to processing and forming and the physical and chemical performance of excellence, the advantage such as cheap, and aluminium foil is
One metallic aluminium directly rolls sheet thermoprint material, and its hot stamping effects is similar to the effect of pure silver foil thermoprint, therefore also known as
White alloy paper tinsel.Owing to the quality of aluminum is soft, ductility is good, there is argenteous gloss, if by the thin slice after calendering, using sodium silicate
Mount Deng material on offset paper, make aluminium foil, also can print.But aluminium foil itself is oxidizable and colour-darkening, rubs, touch
Touching etc. and all can fade, be not therefore suitable for the thermoprint of the Front cover of book and periodical etc. preserved for a long time, in recent years, the use of air-conditioning is increasingly
Many, make air-conditioning heat exchanger heat transmission fin material, commonly referred to as air conditioner aluminium foil with aluminium foil, it needs enough surface corrosion resistance
Can, accordingly, it would be desirable to through Passivation Treatment.
Along with people's enhancing to environmental protection consciousness, chromic application is the most severely limited.In February, 2003
13, European Union issued " waste electronic andelectrical equipment instruction " and " has used some to be harmful to about limiting in electronic electric equipment
Substances Directive ".The former came into force from August 13rd, 2004, be to the effect that exported to 10 big classes of European Union totally 99 kinds electric
Product recycling and processing cost will be born by manufacturer oneself；The latter was then come into force from 1 day July in 2006, mainly forbade to Europe
The electronic and electrical equipment of 6 kinds of harmful substances such as leaded, hydrargyrum, cadmium, Cr VI, poly-dibromodiphenyl ether and poly-bromo biphenyl is sold by alliance, this
Instruction will relate to 8 big class totally 64 kinds of products.Research and develop nontoxic or low toxicity material to exist to substitute chromating technique gesture
Must go.
