Quality requirements for separators

Separator is an important part in battery production, its advantages and disadvantages directly affect the battery's discharge capacity and charge-discharge cycle life, so we must pay attention to the selection and research of battery separators. The quality requirements of the separator should generally have the following requirements

The effect of the separator on the battery

The influence of glass fiber (AGM) separator properties on the performance of sealed lead-acid batteries, including basis weight and thickness uniformity, resilience and compressibility, porosity and acid absorption, pore size, resistance, impurities, etc. The following points are shown: (1) The basis weight and uniformity of the separator are the main factors affecting the uniformity of the battery capacity; (2) The resilience and compressibility of the separator are the guarantee for the tight assembly of the battery, and also the internal separator of the battery. (3) The porosity and acid absorption of the separator are the guarantee of battery capacity, service life and high current discharge performance; (4) The pore size of the separator reflects the Whether the plate can prevent the penetration of lead dendrites; (5) The resistance of the separator directly affects the low temperature start-up performance and high current discharge performance of the battery; (6) The impurities in the separator are the direct cause of the self-polar discharge of the battery.

Structural features of AGM separator maintenance-free battery

AGM separator maintenance-free battery structure features: In order to improve the service life of lead-acid batteries, along with its performance, the positive grids of maintenance-free batteries are generally made of lead-calcium alloys or low-antimony alloys, while the negative grids are made of lead-calcium alloys.

What are the liquid filter materials

Commonly used liquid filter materials are classified as follows: 1. Polypropylene fiber (polypropylene) Polypropylene has good wear resistance and high elastic recovery rate. It is an excellent thermoplastic fiber. Polypropylene felt is often used in low-temperature pulse filter bags in smelting plants and pulse filter bags in chemical and pharmaceutical factories. Polypropylene accuracy range: 0.1--500 microns, maximum temperature 94 degrees. 2. Polyester fiber (polyester) Special polyester fiber has good performance at room temperature and is the main filter material in bag filters. It can withstand the operating temperature of 130 ° C under dry conditions; continuous work above 130 ° C will harden; fade; become brittle, and the temperature will also weaken its strength. Accuracy range: 1--300 microns.

What are the applications of filter materials

There are many types of filter materials, one of which is activated carbon filter material, which has a wide range of applications and can be used in air purification, urban sewage treatment, advanced treatment of drinking water, impurity removal of printing ink, extraction of amino acids and electrolytic nickel, and decolorization of sugar. Because of its strong adsorption capacity, it is also used to remove odors in homes, cars, refrigerators, etc.
