Abstract
The present invention provides processing technology before prime paint coating of an automobile wheel assembly. The processing technology comprises the steps that the automobile wheel assembly is suspended by a corresponding shot blasting hanger and enters a shot-blasting machine to be blasted; compressed air is used to thoroughly clean floating dust, steel shots, etc. of the surface of the automatic wheel assembly work piece; the work piece is suspended by a prime paint hanger; the automatic wheel assembly work piece is degreased in an alkaline bath, primarily washed in water and secondarily washed in water; and the automatic wheel assembly work piece is phosphatized, thirdly washed in water and then washed in water to remove ions. Iron rust, oily soil, etc. on the surface of the automobile wheel assembly work piece which is processed in the modes of shot blasting, water washing, etc. are thoroughly removed, and the automobile wheel assembly work piece accords with processing requirements before prime paint coating of the automobile wheel assembly. Although alkaline degreasing processing is used in the processing technology, used alkali is weak alkali and easily neutralized by acid bases; therefore, the processing technology achieves pollution-free discharge.
Description
(1) technical field
The present invention relates to a kind of automotive wheel oil paint coating pre-treating technology, belong to the paint coating process field.
(2) background technology
Require to have the rust cleaning operation in the treatment process before the automotive wheel assembly primer painting.Now domestic each wheel manufacturer all adopts acid cleaning process to reach the purpose of rust cleaning, and pickling will use strong acid, and this method need be drained a large amount of sour industrial wastewaters that contains, wastewater treatment is difficulty quite, easily cause environmental pollution, and need build special-purpose pickling tube, occupied ground is bigger.
(3) summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of preceding treatment process of automotive wheel assembly primer painting of efficient pollution-free is provided.
The solution that the present invention adopts may further comprise the steps:
A, wheel set hung to enter with corresponding ball blast hanger carry out ball blast in the shot-blasting machine;
B, clean up with the floating ash on the wheel set surface of compressed air after, shot etc. with ball blast;
C, workpiece is hung with swimming lacquer hanger;
D, enter alkaline bath and carry out ungrease treatment;
E, once wash;
F, carry out secondary water washing;
G, workpiece is carried out phosphatization handle;
H, carry out three times the washing;
I, carry out the washing of clean deionization.
The wheel set workpiece that the present invention handles through ball blast, washing etc., its surperficial iron rust, greasy dirt etc. are eliminated totally, meet the processing requirements before the wheel set primer painting.Though the alkali cleaning ungrease treatment is arranged, what use is weak base, easily handles by acid-base neutralization, reaches non-pollution discharge.
(4) description of drawings
Accompanying drawing is the flow chart of the treatment process before the automotive wheel assembly primer painting of the present invention.
Wherein: 1, ball blast, 2, prerinse, 3, reach the standard grade, 4, degreasing, 5, once washing, 6, secondary water washing, 7, phosphatization, 8, three washings, 9, clean deionization washing
(5) specific embodiment
Embodiment: as shown in drawings, the processing technological flow before the automotive wheel assembly primer painting is: ball blast 1, prerinse 2, reach the standard grade 3, degreasing 4, once wash 5, secondary water washing 6, phosphatization 7, three washings 8 and clean deionization washings 9.
Comprise following nine steps:
A, wheel set hung to enter with corresponding ball blast hanger carry out ball blast in the shot-blasting machine;
B, the floating ash of surface of the work, shot etc. are cleaned up with compressed air;
C, workpiece is hung with swimming lacquer hanger;
D, enter alkaline bath and carry out ungrease treatment;
E, once wash;
F, carry out secondary water washing;
G, workpiece is carried out phosphatization handle;
H, carry out three times the washing;
I, carry out the washing of clean deionization.
The present invention no longer adopts general strong acid pickling technology in automotive wheel assembly primer painting pre-treating technology, and has adopted ball blast, washing process, utilizes shot-blasting machine that wheel set is carried out whole ball blast, reaches the requirement of degreasing and rust removal.Solved because of production site lessly, can't set up descaling bath to carry out the problem of processing of rust removing, realized the efficient pollution-free processing.
Claims (1)
1. the treatment process before the automotive wheel assembly primer painting, it is characterized in that: this technology may further comprise the steps:
A, wheel set hung to enter with corresponding ball blast hanger carry out ball blast in the shot-blasting machine;
B, clean up with the floating ash of the wheel set surface of the work of compressed air after, shot etc. with ball blast;
C, workpiece is hung with swimming lacquer hanger;
D, enter alkaline bath and use weak base to carry out ungrease treatment;
E, once wash;
F, carry out secondary water washing;
G, workpiece is carried out phosphatization handle;
H, carry out three times the washing;
I, carry out the washing of clean deionization.
