Abstract
The present invention relates to a pole plate porosity measurement method. The method comprises the steps of weighing a pole plate with active materials attached thereon as M1, measuring the volume of the pole plate as V1, weighing the pole plate as M2 after the pole plate is soaked for a period of time, calculating the volume of the active materials after absorbing water (wherein rho represents the water density), removing the wet active materials on the pole plate from the plate grid of the pole plate, measuring the volume of the plate grid as V3, and calculating. Based on the above method, the porosity of the pole plate can be accurately measured.
Description
Technical field
The present invention relates to a kind of pole plate porosity measuring method.
Background technology
The powder porous electrode that polar plate of lead acid storage battery active substance is made up of Hydrocerussitum (Ceruse), the porosity of porous electrode directly affects the performances such as the capacity of lead-acid accumulator, life-span.At present in lead-acid accumulator manufacture process, production is control paste density and water content finally to carry out the porosity of plate active material.It is very important that the porosity of the pole plate of final molding measures.
Summary of the invention
In order to solve above-mentioned technical problem, the invention provides a kind of pole plate porosity measuring method, comprise the following steps, to weigh to obtain weight M1 with the pole plate of active substance, measure described pole plate volume V1, weight M2 weighed after described pole plate is soaked a period of time, calculated activity material sucks the volume of water(p is the density of water), removes wet plate active material from the grid of pole plate, measures grid volume V3, calculates
Further, measuring described pole plate volume V1 is to put into aqueous solution storage vessel by pole plate, aqueous solution storage vessel communicates with graduated cylinder, graduated cylinder is identical with aqueous solution storage vessel liquid level, in graduated cylinder be connected a level sensing line on electronic balance display, when soaking during water put into by pole plate, in graduated cylinder, liquid level can rise, display body product V1 in electronic display 2.
Further, measuring grid volume V3 is to be removed by wet plate active material, processes the grid obtaining being dried, and puts into aqueous solution storage vessel, and graduated cylinder liquid level rises, and electronic display obtains volume number V3.
Further, when calculated activity material sucks the volume V2 of water, also include the step of temperature by thermometer measure water.
Further, described pole plate soaks a period of time is 2-3 hour.
By the method for the present invention, can accurate measuring pad porosity.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.
The present invention relates to a kind of method measuring polar plate of lead acid storage battery porosity, comprise the following steps, first by with the pole plate of active substance scales/electronic balance weighing record, electronic display can directly display weight M1 dry weight.Aqueous solution storage vessel connects one has the graduated cylinder of exact scale to communicate, graduated cylinder is identical with aqueous solution storage vessel liquid level, in graduated cylinder be connected a level sensing line on electronic balance display, when soaking during water put into by pole plate, in graduated cylinder, liquid level can rise, can directly display volume milliliter number V1 in electronic display 2, this V1 is exactly the volume ml of pole plate.Pole plate will be weighed up and continue to put into immersion 2～4 hours in aqueous solution storage vessel, make the water suction of plate active material maximum saturation, after when pole plate immersion 2～4 is little, pole plate is carried unnecessary water has been drained, it is placed directly in hook upper 5 to weigh reading M2 weight in wet base, being connected displays temperature reading with electronic display with chronothermometer, water density at different temperatures is different, obtains density p water.So plate active material sucks the volume of waterBeing removed by wet plate active material, process the grid obtaining being dried, put into aqueous solution storage vessel, graduated cylinder liquid level rises, and electronic display obtains volume number V3, calculates
In present invention experiment, involved mass unit is a gram g, volume unit milliliter ml, density unit g/ml.The present invention uses Plethysmometry to measure pole plate porosity, easy can quickly measure pole plate porosity.
