Pipeline outer wall painting device
[ technical field ] A method for producing a semiconductor device
The invention relates to a pipeline painting device, in particular to a pipeline outer wall quick painting device.
[ background of the invention ]
The pipeline is known to be an important carrier for conveying liquid such as water supply, gas supply chemical raw materials and the like, the pipeline is mainly made of metal, and the other part of the pipeline is made of plastic, wherein once protective paint on the inner wall and the outer wall of the metal pipeline is stripped and falls off in long-term use, the pipeline made of steel can be contacted with oxygen in the air and is exposed to the open air and exposed to the sun and rain, so that the corrosion reaction is easy to occur; the potential safety hazard and accidents are easily caused by leakage damage after the pipeline is corroded, the loss caused by various corrosion accounts for 3% -4% of the total GDP every year all over the world, and how to delay or prevent the corrosion of the pipeline and resist the corrosion becomes one of important subjects in industrial production and pipeline oil transportation industries.
The surface of the metal pipeline is added with an anticorrosive coating (such as paint) so as to isolate the steel pipeline from being contacted with oxygen in the air, thereby achieving the protection effect.
The maintenance of the metal pipeline is mainly realized by cleaning paint on the surface, removing rust until the metal surface is exposed, and then performing anticorrosive paint brushing operation on the pipeline, namely brushing one antirust paint primer and then brushing two finishes; the common process is carried out by using a paint brush and also using high-pressure paint spraying equipment, but on one hand, the operation mode cannot be observed for the bottom of the pipeline (when the pipeline is erected lower), so that the paint brushing on the bottom of the pipeline is extremely uneven; for erecting higher pipelines, the alternative operation of the upper part and the lower part is time-consuming and labor-consuming.
