Abstract
The invention provides a process for spraying a finish paint for a metal tank body, which comprises the following steps: (1) outer surface processing, i.e. preparing phosphorizing solution according to a weight ratio of water to a film covering agent to a degreasing cleaning agent of (13 to 14):(0.5 to 0.6):(0.5 to 0.6) and uniformly wipe the outer surface of the metal tank body with the phosphating solution; (2) preheating, i.e. placing the metal tank body which is wiped with the phosphating solution on an oven tunnel production line to carry out preheating, wherein the temperature of an oven tunnel is 75 to 85 DEG C, the oven tunnel has a length of 6 to 7m and the metal tank body has a conveying speed of 4 to 5m per minute; (3) paint spraying, i.e. feeding the metal tank body into an electrostatic spraying system to carry out paint spraying on the outer surface of the metal tank body, wherein in the process of spraying a paint, the metal tank body uniformly rotates and the rotating speed is 18 to 22 rounds per minute; and (4) drying, i.e. placing the metal tank body sprayed with the paint in a clean place to carry out natural air-drying. According to the invention, an electrostatic spray gun is adopted to carry out paint spraying; paint mist is reduced; the utilization rate of the paint is high; the process is more environment-friendly; paint cost is effectively reduced; a paint film has higher uniformity; and spraying efficiency is improved.
Description
Technical field
The present invention relates to a kind of paint spraying technique, especially metal can finish paint spraying coating process
.
Background technology
At present, the metal can finish paint spraying general using compressed air that the agitator tank of concrete mixer truck or concrete mixer of take is representative makes commonly to suct paint atomizing in the formula spray gun and become thinner fan-shaped vaporific, spray to tank surface and form coating cloud, the problem that this kind of application mode mainly exists is: even under paint spray booth's circulated air opening, coating cloud is still quite large, the feature of environmental protection is poor, large on the healthy impact of workmen; The retry of paint kettle is dumb, and spray efficiency is low; The corner spraying is not in place; The paint utilization rate is low; Paint film is inhomogeneous.
Summary of the invention
The objective of the invention is for overcoming the above-mentioned shortcoming of metal current tank body finish paint spraying coating process.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of metal can finish paint spraying coating process is provided, comprises the following steps:
(1) outer surface is processed: by weight, water: filming agent: degreased cleaning agent=13～14:0.5～0.6:0.5～0.6, preparation obtains Phosphating Solution, to the even wiping phosphating solution of the outer surface of metal can;
(2) preheating: the metal can after wiping phosphating solution is positioned on the drying tunnel streamline and carries out preheating, and the temperature of drying tunnel is 75～85 ℃, and the length of drying tunnel is 6～7 meters, and the transporting velocity of metal can is 4～5 m/mins;
(3) spray paint: metal can is sent into to electrostatic coating system the metal can outer surface is sprayed paint, metal can Rotating with Uniform while spraying paint, rotary speed is 18～22 rev/mins;
(4) drying: the metal can after spraying paint is placed on to clean place natural air drying.
The described degreased cleaning agent of step (1) is NPE.
The described filming agent of step (1) is phosphoric acid or phosphate.
The present invention adopts electrostatic gun to carry out paint spraying, because charged paint particle almost all is attached to tank surface, effectively reduces coating cloud, and the paint utilization rate is high, and environmental protection more, effectively reduce the paint vehicle cost; Electrostatic adsorption makes the paint film uniformity better; The rifle body is light and, without paint kettle weight, flexible operation is light, reduces labor strength; Because of the high adhesive rate of coating cloud, spraying, with the enamelled coating speed of thickness, has improved spray efficiency.
