Production system of lead acid battery PE separators

Abstract

The invention belongs to the field of lead acid battery technology, and concretely relates to a production system of lead acid battery PE separators. The production system is used for solving the six following problems: a secondary oiling system is used in order guarantee reasonable viscosity of a mixed material; a traditional coating method of a hydrophilic surfactant is changed; a system for prepressing, secondary pressing, and third pressing is used during pressing of a stiffener; a method for opposite pressing with adjustable spacing is employed, pressing distances can be adjusted according to custom demands, adjustment of rollers is not needed, and continuous production can be carried out for improving productivity; three drying systems are provided for a chemical reagent circulating apparatus. The production system has outstanding industrial practicality, and compared with traditional production systems, product quality and production efficiency are greatly improved. The production system is environmental friendly and can protect health of workers. The production system has especially outstanding progress.

Description

Technical field [0001] The invention relates to the technical field of separators in lead-acid batteries, in particular to a production system for PE isolation plates of lead-acid batteries with an improved system method. Background technique [0002] Lead-acid battery PE (high molecular polyethylene) separator (hereinafter referred to as PE separator) is a component that is immersed in the electrolytic solution (usually a sulfuric acid solution) of the lead-acid battery to isolate the positive and negative electrodes. The partition has gone through the history from wooden partitions to rubber partitions, PVC, glass fiber partitions and now PE partitions. The structure of the PE separator used in modern times is usually a bag-shaped body structure, in which an electrode is arranged, and a stepped reinforcing rib is arranged on the side close to the electrode.

AI Technical Summary

Problems solved by technology

[0006] Problem 1: Low-speed and normal-temperature mixing is used in the mixing process used in the prior art

[0007] Problem 2: In the traditional system, there is a paint system at the back end of the system

[0008] Question 3: Reinforcing ribs should be set on the inner surface of the partition

[0009] Problem 4: The temperature difference between the two sides of the roller during the forming process is large

[0010] Question 5: The formed partition needs to go through the oil pumping process

However, after being evaporated to dryness at high temperature, the PE separator will undergo obvious shrinkage and deformation, which will reduce the elongation of the PE separator, and the result is that it is easy to be short-circuited by the substrate burr
