1. Introduction

The battery separator is a non-toxic, odorless, and white product made of ultra-fine glass fiber with a diameter of 0.4~3um through a wet method. It is the core material of a valve-regulated sealed lead-acid battery (VRLA battery for short).

The excellent performance of the battery separator is shown in: good acid corrosion resistance, uniform thickness, high porosity, fast absorption of electrolyte, good tensile strength in both vertical and horizontal directions, and better compression performance to ensure a certain extreme pressure. Insulation performance and so on. The high specific surface area battery diaphragm is mainly used to fix the electrolyte in the battery to provide the hydrogen-oxygen recombination channel produced by the two poles during charging and discharging, preventing the active material from the two poles from falling off, slowing down the formation of lead dendrites, and reducing the loss of electrolyte during the charging and discharging process. , So that VRLA battery achieves the purpose of maintenance-free or less maintenance, and prolongs the service life of the battery.

2. Purpose

UPS power supplies, power systems, railway systems, communication equipment, emergency lights, fire protection and security systems, engines, electric cars and motorcycles, sealed power supplies, solar and wind energy.
