Abstract

An immersion liquid before drying oxygen-free drying machine of lead-acid storage battery negative plate and immersion method relate to the technical field of lead-acid storage battery, wherein the immersion liquid is composed of the mixed solutions of the boric acid solution and the xylitol solution. The lead-acid storage battery negative plate is put into the mixed solutions to immerse for 5-20 min and the immersion temperature of the negative plate is 10-70 degrees centigrade. The negative plate produced by the invention reduces 90% of the water consumption without being rinsed and saves the water consumption and reduces plenty of sewage discharges; the negative plate will not be heated in the storage process and generates few bubbles while adding the electrolyte sulphuric acid and can be immersed under room temperature with convenient operation.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to an impregnating solution and an impregnating method before drying by an anaerobic dryer for negative plates of lead-acid batteries. Background technique [0002] The traditional negative plate of the lead storage battery needs to be rinsed with a large amount of water before drying until the pH value of the water reaches above 5. This process produces a large amount of waste water, and the use of an anaerobic dryer to dry the negative plate does not require rinsing with water. The negative electrode plate dried by an anaerobic dryer has the advantages of extremely low lead oxide content and uniform appearance color. However, there are also disadvantages such as poor storage performance of the dried plate, easy oxidation and heat generation of the plate, and many bubbles in the sulfuric acid solution. Contents of the invention [0003] The technical problem to be so...
