Abstract
The invention discloses an electrophoretic coating technology of neodymium iron boron products. The electrophoretic coating technology of the neodymium iron boron products comprises the following steps that firstly, the neodymium iron boron products are soaked in a pre-dip solution; and then, the neodymium iron boron products obtained after pre-dipping are subject to electrophoretic coating. According to the electrophoretic coating technology of the neodymium iron boron products, before the products enter an electrophoresis tank, the products are soaked in the prepared pre-dip solution firstly, then, electrophoretic operation is carried out, a paint film bonding force of an electrophoretic coating is high, flatness is good, the number of exposed points is small, the thickness of the coating is uniform, and the electrophoretic first-pass yield is greatly improved.
Description
Technical field
The present invention relates to neodymium iron boron process for protecting field, particularly to the electrophoresis depositing process of a kind of neodymium iron boron product.
Background technology
Neodymium iron boron product needs to do electrophoresis coating. But the product appearance first-time qualification rate of the electrophoresis depositing process of existing neodymium iron boron product only has 50%, subject matter is the adhesion of paint film, planarization, and dew point is many, and thickness of coating is uneven.
In neodymium iron boron product electrophoretic techniques, product electrophoresis first-time qualification rate is low, not only increases the labor intensity of workman, have impact on the enthusiasm of workman, and needs to repeat to do over again.
It is disclosed in the information of this background section and is merely intended to increase the understanding of the general background to the present invention, and be not construed as admitting or imply in any form that this information structure is for prior art that persons skilled in the art are known.
Summary of the invention
It is an object of the invention to provide the electrophoresis depositing process of the neodymium iron boron product of a kind of simple and reasonable steps, the electrophoresis depositing process of this neodymium iron boron product adopts before product enters electrophoresis tank, first soak in the pre-immersion configured, then electrophoresis is carried out again, the film adhesion making electrophoresis coating is strong, and planarization is good, and dew point is few, and thickness of coating is equal, electrophoresis first-time qualification rate is also greatly improved.
For achieving the above object, according to the electrophoresis depositing process that the invention provides a kind of neodymium iron boron product, comprise the following steps: first, pre-immersion is soaked neodymium iron boron product; Then, the neodymium iron boron product of pre-soaking is carried out electrophoresis plating.
Preferably, in technique scheme, the composition of pre-immersion includes: resin, color and glacial acetic acid.
Preferably, in technique scheme, the surface electrical of neodymium iron boron product is zinc-plated.
Preferably, in technique scheme, the time that neodymium iron boron product soaks in pre-immersion is 1.5 minutes.
Compared with prior art, there is advantages that the electrophoresis depositing process of this neodymium iron boron product adopts before product enters electrophoresis tank, first soak in the pre-immersion configured, then electrophoresis is carried out again, the film adhesion making electrophoresis coating is strong, and planarization is good, and dew point is few, and thickness of coating is equal, electrophoresis first-time qualification rate is also greatly improved.

Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, it is to be understood that protection scope of the present invention is not by the restriction of detailed description of the invention.
Explicitly indicate that unless otherwise other, otherwise in entire disclosure and claims, term " includes " or its conversion will be understood to comprise the element or ingredient stated at such as " comprising " or " including " etc., and does not get rid of other element or other ingredient.
As it is shown on figure 3, the concrete steps of the electrophoresis depositing process of this neodymium iron boron product include:
First, pre-immersion is soaked neodymium iron boron product;
The electrophoresis tank 1 (as depicted in figs. 1 and 2) of neodymium iron boron product is overall to the left extends 1.5 meters, sets up soaking compartment 2, and the special pre-immersion of soaking compartment 2 inner configuration neodymium iron boron product, pre-immersion main component includes: resin, color and glacial acetic acid. The surface electrical of neodymium iron boron product is zinc-plated, and in pre-soak period, reaction equation is Zn+CH3OOH��Zn(CH3OO)2+H2, pre-immersion effect is exactly that the product surface through soaking is carried out chemical polishing, paints liquid and product surface can fully merge during electrophoresis, and film adhesion improves, and surface can not form bubble, and dew point is removed, and coating uniformity improves, and reaches perfect electrophoresis layer purpose. Soak time sets 1.5 minutes, and production line chain speed is 1m/min, and soaking compartment 1.5 meters is long, and product just runs 1.5 minutes in soaking compartment, also solves, while running, the problem that product needed is rocked. The groove width part lengthened is designed as 0.4 meter according to hanger shape, is effectively reduced the expense joining groove and later maintenance.
Then, the neodymium iron boron product of pre-soaking is carried out electrophoresis plating.
1. the electrophoresis depositing process using the neodymium iron boron product of the present invention achieves following achievement. and thickness of coating inequality problem is solved, and first-time qualification rate reaches 98%, has reached the standard that client needs. 2.. immersion treatment personnel 4 are saved in per tour, save 8 operator altogether for two classes, monthly save 20,000 yuan of salary expens. 3.. when satisfied production, soaking compartment width selects 0.4 meter, and the volume so soaked only needs 500 liters, effectively reduces soak and joins the expense of groove cost and later maintenance, monthly saves 3-5 thousand yuan.
To sum up, the electrophoresis depositing process of this neodymium iron boron product adopts before product enters electrophoresis tank, first soaks in the pre-immersion configured, then electrophoresis is carried out again so that the film adhesion of electrophoresis coating is strong, and planarization is good, dew point is few, and thickness of coating is equal, and electrophoresis first-time qualification rate is also greatly improved.
The aforementioned description to the specific illustrative embodiment of the present invention illustrates that and the purpose of illustration. These describe and are not wishing to limit the invention to disclosed precise forms, and it will be apparent that according to above-mentioned instruction, it is possible to carry out much changing and change. Purpose exemplary embodiment selected and describe is in that to explain the certain principles of the present invention and practical application thereof, so that those skilled in the art is capable of and utilizes the various different exemplary of the present invention and various different selection and change. The scope of the present invention is intended to be limited by claims and equivalents thereof.
