People's living standards continue to improve, the usage amount of air-conditioning are increasing year by year.The air conditioner of China's production in 2005
Up to 53,000,000,200,000 tons of aluminium foil is consumed.The use of air-conditioning is more universal, but air-conditioning is during long-term use, it may appear that
Power consumption increases, many problems such as dust pollution, peculiar smell, bacteria breed.With national energy-saving method and the phase of Law on Environmental Protection
After appearance, air-conditioning constantly develops to miniaturization, lightweight and high performance direction, the function and performance of idle call aluminum fin-stock is carried
Higher requirement is gone out.Heat exchanger of air condition cooling fin is made of the aluminium foil of 1mm or so thickness, in order to obtain good performance,
The aluminium foil cooling fin of the small pitch of fins of generally use, complicated piece shape.
During air conditioner refrigeration, Water vapor condensation in air is simultaneously attached to fin surface, forms " water bridge " between fin, makes
Increase into ventilation resistance, noise increases, the work efficiency drop of heat exchanger, and energy consumption increases；If aluminium foil is directly used in radiator
Fin in the air conditioner of cooling-heating room dual-purpose, is in the environment of alternation of wetting and drying, forms oxygen concentration cell, be easily corroded in use, raw
Into Al2O3.3H2The white powder object of O, is commonly called as " white powder ", in wet condition, makes mould growth in heat exchanger, is sent into the wind
It is indoor and pollute environment.The problems such as in order to solve " water bridge ", " white powder " well, it is necessary to surface coated treatment is carried out to aluminium foil,
Make it have good corrosion resistance and high-hydrophilic energy.
Meanwhile wear-resisting oil can be used when processing air-conditioner fin, later stage fin can be generated during secondary baking a large amount of
Flue gas pollutes environment, causes shopwork bad environments, health is damaged very big, while wastes many wear-resisting
Oil.
Self-lubricating anticorrosive composite coating structure has the function of anti-corrosion, wear-resisting, super hydrophilic and self-lubricating, not only economic but also ring
It protects, can be widely used for the necks such as spacecraft, aircraft, satellite, rocket, atomic power device, instrument and meter, vehicle, ship, lathe punching press
Domain.

The beneficial effects of the utility model are：With excellent anti-corrosion capability, surface friction factor can be effectively reduced, is carried
High surface lubrication and wearability；In the case where lubricating grease cannot play a role, it can substitute lubricating grease, in high temperature, strong spoke
It penetrates, in deep-etching, high vacuum and other special medias, frictional interface is made to be lubricated well, while give effective anti-corrosion
Erosion protection, reduces abrasion.Hydrophile function is cleverly introduced in lubricant layer, surface layer has super hydrophilicity, water droplet contact angle
It goes to zero, surface blot is taken away by the gravity of uniform water film, there is splendid self-cleaning ability, while can also allow self-lubricating
It is better.
