Abstract
The invention relates to a method for spraying paint on a turned edge of a steel barrel. The method is characterized by comprising the following steps of: (1) outer surface treatment: preparing phosphorization solution from water, coating agent and degreasing cleaning agent in a weight ratio of 10-12: 0.3-0.4: 0.3-0.4, and uniformly wiping the phosphorization solution on the outer surface of the steel barrel on a barrel brushing machine; (2) pre-heating: placing the steel barrel wiped with the phosphorization solution on a production line of a drying passage for preheating, wherein the temperature of the drying passage is 60 to 70 DEG C, the length of the drying passage is 3 to 10 meters, and the conveying speed of the steel barrel is 2.8 to 3.7 meters per minute; (3) spraying: conveying the steel barrel to a paint spraying system and spraying the paint on the steel barrel; and (4) paint spraying on the turned edge: spraying the paint on the turned edge of the paint sprayed steel barrel by using a spray gun, wherein the steel barrel rotates uniformly when spraying the paint, and the rotating speed is 24 to 26 revolutions per minute. The degreasing cleaning agent is nonylphenol polyoxyethylene ether. The coating agent is phosphoric acid and/or phosphate. The method is convenient to operate and effective; and the paint on the turned edge of the steel barrel is attractive and hasgood adhesive force.
Description
Technical field
The present invention relates to a kind of spraying technology of paint, the spraying method of especially a kind of steel drum crimping place paint belongs to steel drum and makes the field.
Background technology
Along with global economical integration, the steel drum manufacturing industry is used in increasing industry as a traditional industry, and packing also increases with the goods export volume year by year, and use amount increases year by year, and the steel drum industry also progressively develops to the automatic assembly line operation.Therefore steel drum manufacturing enterprise complies with growth requirement, and is just breaking traditional production process and product structure, constantly studies the developing direction of steel drum technology, and adds great development dynamics and new technology application of new.Traditional steel drum appearance lacquer spraying technique is to clamp wheel through three to clamp crimping, drives the steel drum rotation, and the spray gun opsition dependent is arranged sprayed surface paint.During with this explained hereafter, clamp wheel clamp the crimping paint spray of crimping place less than, need method touch-up paint by hand, the inhomogeneous meeting of touch-up paint cause more or less influence attractive in appearance, also incompatible in automatic assembly line production.So the spraying method that must seek a kind of steel drum crimping paint is attractive in appearance and adhesive force good to reach crimping paint, thereby property production in enormous quantities on the commercial production streamline.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, the spraying method of a kind of easy to operate, effective steel drum crimping place paint is provided.
According to technical scheme provided by the invention, the spraying method of said steel drum crimping place paint comprises following processing step:
(1) outer surface is handled: by weight water: filming agent: degreased cleaning agent=10 ~ 12:0.3 ~ 0.4:0.3 ~ 0.4, preparation obtains phosphatization liquid, on barrel brushing machine to the even wiping phosphatization of the outer surface of steel drum liquid;
(2) preheating: the steel drum behind the wiping phosphatization liquid is positioned over carries out preheating on the drying tunnel streamline, the temperature of drying tunnel is 60 ~ 70 ℃, and the length of drying tunnel is 8 ~ 10 meters, and the transporting velocity of steel drum is 2.8 ~ 3.7 meters/minute;
(3) spray paint: steel drum is sent into paint spraying system steel drum is sprayed paint;
(4) spray paint in the crimping place: with spray gun the steel drum crimping after spraying paint is sprayed paint, steel drum Rotating with Uniform when spraying paint, rotary speed are 24 ~ 26 rev/mins.
Said degreased cleaning agent is a NPE.
Said filming agent is phosphoric acid and/or phosphate.
It is easy to operate, effective that the present invention carries out paint spraying to steel drum crimping place, and the paint of steel drum crimping is attractive in appearance and adhesive force good, and can on the commercial production streamline, produce in enormous quantities.
