Embodiment 1

[0029] This embodiment provides an acid-absorbing pillow suitable for lead-acid batteries and a preparation method thereof.

[0030] See figure 1 The main material of the acid-absorbing pillow 3 of the present embodiment is alkaline neutralizing powder, and the composition formula of this alkaline neutralizing powder is: neutralizing agent (sodium carbonate and / or potassium carbonate 50-90 parts by weight), swelling Loosening agent (10-30 parts by weight of powdery non-woven fabric and / or powdery absorbent cotton), auxiliary agent (1-5 parts by weight of diatomaceous earth), dispersant (1-3 parts by weight of sodium stearate), acid Alkali indicator (0.02-0.5 parts by weight of methyl red). The particles of the above components can be very coarse, and ordinary powders can be used. The above components are mixed evenly by a stirring device such as a stirring tank and packed. All the above-mentioned components can be of industrial grade purity.

[0031]Specifically, in this e...

Abstract

The invention discloses an acid liquid neutralizing bag, namely an acid absorbing pillow, suitable for a lead-acid storage battery, and a preparation method of the pillow. The major material of the acid absorbing pillow is an alkaline neutralizing powder; the alkaline neutralizing powder is prepared from the following components in parts by weight: 50-90 parts of neutralizer, 10-30 parts of swelling agent, 1-5 parts of auxiliaries, 1-3 parts of dispersant and 0.02-0.5 part of acid-base indicator. Various components can be ground into thick particles or common powder. The components are evenly mixed by use of a stirring kettle and the like and packaged. The acid absorbing pillow is manufactured by packaging the alkaline neutralizing powder with a bag manufactured by use of a material having an acid liquid adsorption function, such as adsorption cotton and hydrophilic non-woven cloth. The acid absorbing pillow is stable and reliable, low in cost, simple to prepare and visual in effect, and has excellent practicability and operability.

Description

technical field [0001] The invention relates to the field of accessory equipment of lead-acid batteries, in particular to a method for preparing an acid absorption pillow suitable for acid solution neutralization tanks of lead-acid batteries. Background technique [0002] Lead-acid batteries are the most widely used industrial batteries, accounting for more than 90% of the entire industrial battery consumption. Lead-acid batteries are widely used in nuclear power, UPS, communications, automobiles, railways and other industrial fields, and are popular because of their relatively low cost and ease of use. [0003] However, lead-acid batteries also have certain disadvantages, such as improper use, including battery rupture, explosion, and excessive water addition, there may be acid spillage. Since the lead-acid battery uses medium-concentration sulfuric acid with a specific gravity of 1.28-1.30, its extremely strong corrosiveness has certain requirements for the operator and t...
