Embodiment Construction

[0020] As shown in Figure 1, the manufacturing process of the melt-blown non-woven fiber reinforced plate includes the following steps:

[0021] Grid casting 1: the plate is cast from lead-calcium-tin-aluminum alloy into a grid;

[0022] Paste 2: Mix lead powder with dilute sulfuric acid and additives to make lead paste;

[0023] Smear 3: Fill and fill the positive lead paste;

[0024] Curing 4: Put it in a curing room with a relative humidity of 98% to 100% and a temperature of 50 to 55°C for 24 hours, then gradually reduce the relative humidity to 60 to 95%, and adjust the temperature to 60 to 75°C to maintain More than 24 hours to fully oxidize the active material, make it harden, dry, and adhere well to the grid;

[0025] Formation 5: Then pair the cured positive and negative plates into dilute sulfuric acid and turn on electricity to convert the lead paste on the positive plate into lead dioxide, and the lead paste on the negative plate into spongy lead;

[0026] Post-...

Abstract

The invention discloses a manufacturing technique for strengthening a polar plate with melt-blown non woven fabric. After the dust of a manufactured finished polar plate is removed, a melt-blown non woven fabric device is adopted to spray a PP plastic or a polyester material which are comprise with hot adhesive under a melt state to form the non woven fabric, the non woven fabric is uniformly attached to the surface of the finished polar plate to form a non woven fabric layer and spray plastic strips on the surface of the non woven fabric layer. The manufacturing technique of the invention sprays the non woven fabric layer on the surface of the finished polar plate; as the fabric in the melt state comprises the hot adhesive component, thus the non woven fabric layer has excellent adhesive attraction; and as the directions of the sprayed non woven fabric are unorderly, a formed covering layer is porous; both the hole rate and aperture can be changed by adjusting a melt-blown device; the adhesive intensity can be changed by adjusting the content of the hot adhesive and adjusting the pressure of the melt-blown device, thus not only being capable of improving the intensity of the polar plate to prevent active substances from falling off, but also being capable of leading sulphuric acid solution to be dispersed into the inside of the polar plate successfully; an inner resistance is extremely low; the property of the polar plate can be improve; the technique is simplified and the manufacture cost is reduced.

Description

【Technical field】 [0001] The invention relates to a lead-acid storage battery, in particular to a manufacturing process of a pole plate used in the lead-acid storage battery. 【Background technique】 [0002] Traditional lead-acid batteries are mainly composed of battery tanks, battery covers, plates, dilute sulfuric acid electrolytes, separators and accessories. The manufacturing process of lead-acid batteries includes lead powder manufacturing, grid casting, plate manufacturing, plate formation and battery assembly. Among them, lead powder manufacturing is to process 1# electrolytic lead into lead powder that meets the requirements of battery production technology. The main components of lead powder are lead oxide and metallic lead. The quality of lead powder has a very close relationship with the quality of the manufactured product. In my country, the Shimadzu method is often used to produce lead powder, while in Europe and America, the Barton method is often used to prod...
