Production process for PE isolation plate of lead-acid storage battery

Abstract

The invention belongs to the technical field of a lead-acid storage battery, and specifically to a production process for a PE isolation plate of the lead-acid storage battery. The invention aims to solve problems existing in six aspects; a second oil injection process is adopted to ensure that a mixed material has reasonable viscosity; the conventional coating process for a hydrophilic surfactant is changed; a pressing process which includes the steps of pre-pressing, pressing for the second time and pressing for the third time is adopted for pressing reinforcing ribs; an opposite pressing method with adjustable spacings is adopted, so that the pressing distance can be adjusted according to requirements of customers without adjusting rollers, so that continuous production can be realized and the productivity can be increased; and a process of recycling a chemical reagent and a process of drying in three modes are performed. By adoption of the production process, the production process obtains prominent industrial practicability; compared with the conventional production process, the product quality and the production efficiency are greatly improved by the production process provided by the invention; and in addition, the production process is environment-friendly and can protect health of workers, so that the production process has an outstanding improvement effect.

Description

technical field [0001] The invention relates to the technical field of a separator in a lead-acid battery, in particular to a production process of a PE separator for a lead-acid battery with an improved process method. Background technique [0002] Lead-acid battery PE (polymer polyethylene) separator (hereinafter referred to as PE separator) is a component soaked in the electrolytic solution (generally sulfuric acid solution) of lead-acid battery to isolate the positive and negative electrodes. The clapboard has gone through the process from wooden clapboard to rubber clapboard, PVC, glass fiber clapboard to the current PE clapboard. The structure of the PE separator used in modern times is usually a bag-like structure, in which electrodes are arranged, and stepped ribs are arranged on the side close to the electrodes. In "Lead-Acid Battery Separator", publication time: 2010-11, publisher: Chemical Industry, author: Shi Guang, Chen Hongyu. The book fully introduces the h...

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] Question 2: There is a paint process at the back end of the process in the traditional process

[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
