Abstract

The invention discloses a supercritical CO2 fluid spraying system realizing automatic coating proportioning. The system comprises an automatic coating proportioning supply system, a supercritical CO2gas supply system, a mixing system and a spraying system, and is characterized in that after being automatically weighed, proportioned and pressurized by the automatic coating proportioning supply system, a coating raw material is mixed with high-pressure CO2 provided by the supercritical CO2 gas supply system in a mixing kettle, then is adjusted by a throttle valve 3, and finally sprayed on the surface of an object to be sprayed after passing through an adjustable spray pipe and a spray gun. According to the system, part or all of a thinner in a traditional spraying process is replaced with supercritical CO2, so that pollution to the environment and the harm to a human body in the spraying process are reduced or even eliminated, and the advantages of reducing the cost and improving the spraying effect and efficiency can be achieved; and meanwhile, industrial requirements of automatic proportioning of the supercritical CO2 fluid spraying system is met through adopting the automatic coating proportioning supply system, and therefore the system has a wide application prospect.

Description

technical field [0001] The invention relates to a paint spraying system, in particular to a paint automatic batching supercritical CO 2 Fluid spray system. Background technique [0002] The traditional paint spraying process uses a large amount of volatile organic compounds as thinners, and releases a large amount of volatile organic compounds VOCs during the spraying process, which will not only pollute the environment, but also endanger human health. The country has also issued relevant laws and regulations to restrict the use of volatile organic compounds. Non-toxic organic compounds, so it is necessary to find a new coating spraying process. [0003] Compared with traditional paint spraying process, supercritical CO 2 Spraying replaces part or all of the volatile thinners such as benzene and toluene in the spraying process with supercritical CO 2 , not only can greatly reduce or even completely eliminate VOCs generated during the spraying process, effectively protect ...
