Abstract

The invention relates to the technical field of basic electric elements, in particular to glass wool used for an AGM separating plate. The glass wool used for the AGM separating plate is prepared fromthe following raw materials in parts by weight: 80-120 parts of compound glass wool fiber yarns, 10-20 parts of a binder and 2-7 parts of a corrosion inhibitor. The glass wool used for the AGM separating plate is high in purity and good in mechanical strength and chemical stability and has good acid and base resistance and high use intensity, and the AGM separating plate prepared by adopting theglass wool used for the AGM separating plate has relatively good usability in a lead-acid storage battery.

Description

Technical field [0001] The invention relates to the technical field of basic electrical components, in particular to a glass wool for AGM partitions. Background technique [0002] In traditional flooded lead-acid batteries, separators are used as inert separators to prevent short circuits between positive and negative electrodes. They need to have good ionic conductivity, the manufacturing method should match the production process, and the physical and chemical properties have long-term stability. Ultra-fine glass fiber separator (AGM) is a new type of separator material developed in recent years. It is made of ultra-fine glass fiber through emulsification, paper washing and drying. AGM separator has the advantages of good acid resistance, high porosity, small pore size, high liquid absorption rate, low resistance, etc., and has been widely used in liquid valve-regulated lead-acid batteries. The chemical composition of glass wool is a key factor affecting the performance of the...
