Abstract
The invention discloses a method for coating lead plaster on a felt plate grid. According to the method, a coating method simultaneously performing high-pressure spray coating and negative pressure adsorption is used. The method comprises the following concrete process steps of A, diluting the lead paster into slurry; B, flatly paving the felt plate grid; C, performing spray coating operation; D, performing low-temperature drying. After the implementation of the method, the slurry and the felt plate grid can be sufficiently combined; an active substance layer formed after the slurry curing is compact. The method has the other characteristics that partial slurry is directly sucked into pores of the felt plate grid by negative pressure; for the result, on one hand, the bonding intensity of the lead plaster and the felt plate grid can be enhanced, and on the other hand, the adhesion quantity of the slurry can be increased. A pole plate prepared by using the method provided by the invention can carry more active substances; in addition, the combination intensity is high; the matching requirements of a lead-acid storage battery are completely met.
Description
Technical field
The present invention relates to one kind is coated with lead plaster method on grid, in particular it relates to one kind is in non-felt scutum
Lead plaster method is coated with grid, the method belongs to a technology of lead-acid accumulator manufacturing technology field.
Background technology
Lead-acid accumulator is a kind of traditional secondary power supply equipment, and it is near that it bases oneself upon market with excellent performance and cost performance
150 years.Even so, lead-acid accumulator is not very perfect product, there is congenital defect in it, that is, built-in lead
Part and sulphuric acid have environmental pollution during manufacture and use, and under existing environmental protection policy, lead-acid accumulator is listed in emphasis
Supervision product.The industry, in order to accomplish sustained improvement lead-acid accumulator, strives reducing polluter from structure design, most important
One of technical measures are to abandon lead scutum grid, use non-lead scutum grid instead and integrally substitute.In recent years, successively developed in the industry use
The non-lead material such as felt, cloth or cystosepiment as make grid base material, because of the physical property of these succedaneum materials and lead material
Completely different, so the existing outer process applying lead plaster is completely unsuitable for the production of non-lead scutum grid.Newly develop these
Non-lead scutum grid will expect industrialized production it is necessary to seek a kind of brand-new lead plaster coating process.Now, in the industry in this respect
Achievement in research is more, and major processes have two-sided painting, extruding to apply, negative pressure applies, vibration applies and ultrasound wave applies, and these lead plasters are coated with
Although method implements do not have technical difficulty, it is capable of industrial applications.But, these lead plaster coating processes are in actual production
More or less Shortcomings in journey, are mainly reflected in that lead plaster coating quality is not good enough, and the activity making pole plate will be sought survival with supporting
In gap.For example, when felt scutum grid making double spread lead plaster, because prior art is only high pressure painting, the pulpous state lead of ejection
Cream can only stick to felt material surface it is impossible to enter in the hole that felt material enriches, so the pole plate made is because amount containing lead plaster is not enough
Poor activity.Extruding applies, vibration applies and ultrasound wave painting is all to strengthen lead plaster coating quality by applying external force, but these methods
Felt scutum grid intensity used be there are certain requirements.It is known that the intensity of felt matter can not show a candle to lead material intensity, therefore these coatings
There is a problem of during method practical application that work efficiency is not high and quality control is difficult.Although negative pressure applies contributes to lead plaster entrance felt scutum grid
Hole in, contribute to increase shape pole plate amount containing lead plaster.But, negative pressure applies the density of material size to felt scutum grid to be had relatively
High request, along with negative pressure absolute value is relatively low, makees lead plaster coating by negative pressure merely, the poor product quality opposite sex obtaining is larger, no
Meet the supporting requirement of batch production.
Content of the invention
Present invention is generally directed to the deficiencies in the prior art, a kind of coating lead plaster method, the method on felt scutum grid is proposed
Supporting process conditions are required low, be easy to implement, coating quality is good, production efficiency is high it is most important that this technique is to felt matter
Grid intensity and density requirements are not high.
The present invention is achieved through the following technical solutions technical goal.
Felt scutum grid are coated with lead plaster method, it thes improvement is that：Coating lead plaster adopts high pressure painting to inhale with negative pressure
The method of attached common implementing, concrete technology step is as follows：
A, lead plaster are diluted to pulp-like
Take the lead plaster of routinely proportioning system, add pure water 40g～100g by every kg lead plaster and be in harmonious proportion, then through 5～
10min stirs into pulp-like；
B, tiling felt scutum grid
Felt scutum grid are tiled on work top, work top is provided with the negative port of -0.04～-0.1MPa, negative port
Uniform through hole on UNICOM's work top, acts on positioning workpiece using negative-pressure adsorption, and follow-up spraying is still enterprising in this work top
OK；
C, spraying operation
Inject the slurry mixed well toward in spray gun, spray pressure is 0.45～1.2MPa, gun slot end anomaly is layered on work top
The vertical dimension of upper felt scutum grid is 50～150mm, and through 1.0～3.0mm, spraying method is spray gun to gun slot or workbench comes and goes
At the uniform velocity move, coming and going at the uniform velocity mobile is to move left and right it is also possible to move forward and backward, translational speed 0.5～0.8m/s, when implementing spraying
Felt scutum grid retinue on work top for the absorption, after simultaneously spraying finishes, felt scutum grid is made overall 180 ° of upsets, still here
Make another side spraying with same technological parameter, felt scutum grid form pole plate blank after double spread lead plaster on work top；
D, oven drying at low temperature
Pole plate blank is flat in 40～60 DEG C of stove, after oven drying at low temperature 24～36h, in the cured scutum grid in felt of slurry
Form pole plate finished product.
As further improvement project, the density of material of described felt scutum grid is 0.07～0.19g/cm3.
The present invention compared with prior art, has the positive effect that：
1st, using negative-pressure adsorption felt scutum grid on work top, it is convenient to load and unload, and positioning is reliable；
2nd, when high pressure coating lead plaster implemented by spray gun, the work top putting felt scutum grid connects negative pressure, and negative pressure contributes to lead plaster and enters
Enter in the hole of felt material, thus increasing the lead plaster amount of pole plate finished product；
3rd, from as flexible member, absorption is in flat on work top to felt scutum grid, and coating lead plaster is smooth in this situation
The good, efficiency high of property；
4th, work top has support shield effect to the felt scutum grid of absorption, thus less demanding to the density of material of felt scutum grid,
Therefore felt material is drawn materials easily.
Specific embodiment
