Description
Technical field
The present invention relates to solar paint field, more particularly to a kind of solar energy highly effective absorbing coating.
Background technology
Technical and economic performance influence of the solar energy highly effective absorber coatings on Solar use is very big, to improve solar energy equipment
Rate, reduce cost, various countries solar energy scientific worker attaches great importance to studying, developing solar energy highly effective absorber coatings, ground
A variety of coatings are made, some has been used for producing, and achieves good result.Electroplated coating is the one of solar energy highly effective absorbing material
Kind of mature technology, is divided into black chrome coating or black nickel coating, and the efficient absorption of black chrome coating is respectively 0. than α and transmitting ratio ε
93-0.97 and 0.07-0.15, α/ε is 6~13, has excellent spectral selection.The heat of black chrome coating is steady
Qualitative and high temperature resistant property is also fine, can long-term stable operation at 300 DEG C suitable for hot conditions.In addition, black chrome coating is also
With preferable weatherability and corrosion resistance.But the electroplating black chromium technique used now, current density it is big (15~200A/
Dm2), solution conductivity is poor, can produce substantial amounts of Joule heat, it is necessary to which normal life could be maintained with vented exhaust by cooling down during plating
Production.In addition, black chromium is plated in non-copper piece, it is necessary to which first copper pre-plating, then bright nickel plating, last black chromium plating, production cost are higher.It is black
Nickel coating is mostly nickel-alloy coating, and it is formed changes with electroplate liquid composition and sedimentary condition.The electroplate liquid of black nickel is divided into two
Class, i.e. zinc sulfate electroplate liquid and the electroplate liquid of salt containing molybdic acid.The black nickel coating obtained by first kind plating solution, nickeliferous 40%~
60%, it is about 20%~30% containing zinc.The efficient absorption of black nickel coating than α up to 0.93~0.96, heat emission ratio
ε be 0.08~0.15, α/ε close to 6~12, its efficient absorption performance is preferable.Black nickel coating is very thin, in order to improve
The adhesion and corrosion resistance of coating and matrix, frequently with inter coat (such as Ni, Cu, Cd) or double-deck nickel coating.Due to black
Heat endurance, the corrosion resistance of nickel coating are poor, are usually applicable only to low-temperature solar energy heat utilization.With the development of science and technology, also go out
The technologies such as existing electrochemical surface conversion coatings, vacuum plating coating and pigment coating, coating type sun efficient absorption coating is one
The optical surface of kind diffusion, is made up of pigment and binding agent two parts.
