Abstract
The invention discloses a cathode electrophoretic paint scaffold and a manufacturing method thereof. A cathode electrophoretic paint scaffold manufacturing method, comprising dust removal through water washing, rust and ferric oxide removal through acid washing, oil removal through water washing, acid removal through passivation, hydrochloric acid removal through phosphating, removal of phosphating substances through water washing, upper cathode electrophoresis, foam removal through water washing and oven drying, is performed on the outer surface of the scaffold, and comprises the steps of (1) dust removal through water washing, (2) rust and ferric oxide removal through acid washing, (3) oil removal through water washing, (4) acid removal through passivation, (5) hydrochloric acid removal through phosphating, (6) removal of phosphating substances through water washing, (7) upper cathode electrophoresis, (8) foam removal through water washing, and (9) oven drying. The scaffold, painted by electrophoretic paint is long in protection period and high in adhesive capacity, cannot generate the paint falling phenomenon in collision, resists the corrosion, is more beautiful, and is higher in repeated use rate; and the maintenance cost of the electrophoretic paint scaffold is far lower than that of a general paint scaffold.
Description
Technical field
The present invention relates to building appliance, particularly to a kind of cathode electrodip painting scaffold and manufacture method thereof.
Background technology
Electrophoresis is a kind of new technology mode of scaffold surface treatment, and electrophoresis is one of method of the most effective most environmental protection of coating metal workpiece, is mainly used in the process of automobile metal appearance both at home and abroad. Electrophoresis is to be immersed in the coated article with electric conductivity to fill in the electrophoretic coating groove that water-reducible concentration is relatively low as negative electrode (or anode), groove separately arranges corresponding anode (or negative electrode), connect after unidirectional current a period of time between the two poles of the earth, deposit on coated article surface uniformly fine and closely woven, not by a kind of special coating process of water dissolution film.
Electrophoresis process is divided into anodic electrophoresis and ability cathode electrophoresis. If coating particle is electronegative, workpiece is anode, and coating particle deposits film forming at workpiece under electric field force effect and is called anodic electrophoresis; Otherwise, if coating particle positively charged, workpiece is negative electrode, and coating particle deposits film forming on workpiece and is called ability cathode electrophoresis.
The feature of anodic electrophoresis is: cost of material cheap (generally than ability cathode electrophoresis cheap 50%); Equipment is relatively simple, small investment (generally than ability cathode electrophoresis cheap 30%); Technology requires relatively low; Corrosion resistance coating can relatively ability cathode electrophoresis poor (being about the 1/4 of the ability cathode electrophoresis life-span).
In view of this, a kind of cathode electrodip painting scaffold and manufacture method thereof are arisen at the historic moment.
Summary of the invention
The invention provides a kind of cathode electrodip painting scaffold and manufacture method thereof, overcome the difficulty of prior art, the scaffold protection period length of electrophoretic paint application, adhesive ability are strong, and collision does not have coat of paint obscission; The little harmful substance that human body is not had of anticorrosion in electrophoretic paint chemical industry coating, and electrophoretic paint can realize full automation, mechanization and not only alleviate labor intensity, and add productivity ratio; Cathode electrodip painting scaffold anticorrosion, more attractive. Cathode electrodip painting scaffold repeat usage is higher, and cost of upkeep is well below common paint scaffold.
The invention provides a kind of cathode electrodip painting scaffold, the outer surface of scaffold carry out including washing ash disposal, acid pickling and rust removing except ferrum oxide, washing oil removing, passivation go acid, phosphatization desalt acid, washing dephosphorization compound matter, on the ability cathode electrophoresis dried of ability cathode electrophoresis, washing foam removal and baking box.
Present invention also offers the manufacture method of a kind of cathode electrodip painting scaffold, comprise the following steps:
(1) washing ash disposal;
(2) acid pickling and rust removing removes ferrum oxide;
(3) washing oil removing;
(4) acid is gone in passivation;
(5) phosphatization desalts acid;
(6) washing dephosphorization compound matter;
(7) upper ability cathode electrophoresis;
(8) washing foam removal; And
(9) baking box is dried.
The cathode electrodip painting scaffold of the present invention adopts ability cathode electrophoresis, and the reason that cathodic electrocoat corrosion resistance is high is: workpiece is negative electrode, does not occur anodic solution, surface of the work and phosphating coat not to destroy; Electrophoretic coating (is generally resinamines) to metal protective effect, and paint valency height used is of fine quality.
Negative electrode cathode electrodip painting scaffold also has the advantage that
1, owing to being that scaffold upright rod, cross bar etc. are immersed directly in coatings tank, so the inside and outside wall of vertical rod, cross bar is all painted uniform application does not have any dead angle.
2, electrophoretic paint is that coating flows along with both positive and negative polarity magnetic field by connecting unidirectional current, so the highly uniform consistency of thickness of the coating on scaffold surface and do not have the phenomenon of sagging;
3, the scaffold protection period length of electrophoretic paint application, adhesive ability are strong, and collision does not have coat of paint obscission;
4, the little harmful substance that human body is not had of anticorrosion in electrophoretic paint chemical industry coating, and electrophoretic paint can realize full automation, mechanization and not only alleviate labor intensity, and add productivity ratio;
5, the utilization rate of coating is high, up to more than 95% even 100%. Owing to the solids content of tank liquor is low, viscosity is little, the coating that coated article is taken out of is few, especially the application of hyperfiltration technique, implements coating process closed circulation, and the coating response rate is high;
6, cathode electrodip painting scaffold anticorrosion, more attractive. Cathode electrodip painting scaffold repeat usage is higher, and cost of upkeep is well below common paint scaffold.
The present invention is further illustrated below in conjunction with drawings and Examples.
