Description
Technical field
The present invention relates to a kind of coating process, particularly a kind of biabsorption formula air-source heat pump hot water fin coating process.
Background technology
Air-source heat pump hot water all needs hot water preparing throughout the year, due to its accessibility, uses very general in life.
Traditional air-source heat pump hot water, mainly through stringed alumium fin on copper pipe, by blower fan by air circulation flow through aluminum fin-stock, in copper pipe, low temperature liquid refrigeration agent is by aluminum fin-stock, from air, absorb heat.But this kind of air-source heat pump hot water can only heat in absorption cycle air, to the radiant heat absorbent weak effect in sunlight, causes structure heating effect poor; Therefore the biabsorption formula air-source heat pump hot water fin coating process that a kind of heat absorption of development is good, heating effect is strong is badly in need of.
Summary of the invention
The technical problem to be solved in the present invention is to provide the biabsorption formula air-source heat pump hot water fin coating process that a kind of heat absorption is good, heating effect is strong.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of biabsorption formula air-source heat pump hot water fin coating process, and its innovative point is: this coating process is specific as follows:
(1) clean is carried out to fin surface;
(2) electroless copper is adopted to cover one deck high infrared reflection film at fin surface;
(3) adopt single nickel salt, zinc sulfate, potassium sulfocyanate, boric acid and sodium sulfate at the temperature of 21 DEG C ~ 35 DEG C, configure the heat absorbing coating containing black nickel element;
(4) by the surface of the heat absorbing coating surge containing black nickel element to aluminum fin-stock;
Further, in described step (2), the thickness of high infrared reflection film is 0.013 ~ 0.017mg/cm
3.
Further, double-deck surge mode is adopted to carry out coating in described step (4).
Further, described coat-thickness is 0.052 ~ 0.067mg/cm
3.
Further, in described step (4), the coating specific absorption α of black nickel element is 0.93 ~ 0.96, and heat emission is 0.08 ~ 0.15 than ε.
The invention has the advantages that:
(1) biabsorption formula air-source heat pump hot water covers high infrared reflection film and the heat absorbing coating containing black nickel element successively at its fin surface, can not only heat in absorption cycle air, and when there being sunlight, heat energy in abundant absorption sunlight, improve the heat absorption capacity of air-source heat pump hot water, heating capacity, efficiency are all greatly improved.
(2) have the solar time in envrionment temperature lower than 5 DEG C, fin can absorb heat, because fin temperature is higher than dew-point temperature, thus effectively avoids fin frosting and causes heating performance to decline and the heat waster caused that defrosts.
(3) fin surface is coated with one deck high infrared reflection film, and is 0.013 ~ 0.017mg/cm by gauge control
3, this high infrared reflection film has highly reflective, and with the heat absorbing coating compound use containing black nickel element, make the specific absorption of radiation higher.
(4) heat absorbing coating containing black nickel element adopts the mode of double-deck surge to cover, and is 0.052 ~ 0.067mg/cm by gauge control
3, effectively raise bonding force and the solidity to corrosion of coating and matrix.
(5) the coating specific absorption α of black nickel element is 0.93 ~ 0.96, heat emission than ε be 0.08 ~ 0.15, α/ε close to 6 ~ 12, simultaneously black coating does not reflect the light of any color, and therefore can absorb the heat energy in the light of any color, its absorptive character are better.
