Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0031] A method for testing the acid absorption saturation of battery separators, comprising the steps of:
[0032] a. will be as figure 1 , figure 2 The battery separator 11 shown and the corresponding pole plates are put together in the lower barrel body 15 of a test case 1, then the test case is placed on a movable support 3, and the outlet of the bottom of the lower barrel body is sealed and connected. One section of the liquid outlet hose 17 at the liquid hole 14 is higher than the liquid inlet hole 161 arranged on the upper part of the test case.
[0033] The test case in this embodiment includes the lower barrel and the upper cover 16 that is closed at the opening of the lower barrel, and the pole plates and battery separators put into the lower barrel should be closely attached to each other. . In addition, the liquid inlet hole ca...

The invention discloses a method for testing acid absorption saturation of a battery separator, which comprises the following steps of: placing the battery separator into a test housing and then placing the test housing on a movable support, and enabling one section of a liquid outlet hose sealably connected to a liquid outlet hole at the bottom of the test housing to be higher than a liquid inlethole arranged at the upper part of the test housing; injecting a weighed acid liquid into the test housing through the liquid inlet hole to enable the acid liquid to infiltrate the battery separator;inserting the open end of the liquid outlet hose into a bottle opening of an acid liquid collection bottle, reducing the height of the acid liquid collection bottle to be lower than the liquid outlethole in the bottom of a lower barrel body gradually, so that the acid liquid in the test housing flow into the acid liquid collection bottle through the liquid outlet hose; and weighing the weight ofthe acid liquid in the acid liquid collection bottle to obtain the weight difference of the acid liquid before and after testing, so that the acid absorption saturation of the battery separator can be calculated. According to the method for testing acid absorption saturation of the battery separator, the structure is simple, the working intensity of testing workers can be remarkably reduced, andthe testing precision can be improved.
Description
technical field [0001] The invention relates to the technical field of lead-acid battery manufacturing, in particular to a test method for detecting the acid saturation of separators of lead-acid batteries. Background technique [0002] In the manufacturing process of lead-acid batteries, it is necessary to detect the acid absorption saturation of the battery separator. The so-called acid absorption saturation is the ratio between the actual acid absorption of the battery separator and the saturated acid absorption. Specifically, add the weighed acid solution into the battery casing with the positive and negative plates and the battery separator, after a certain period of time, part of the acid solution is absorbed by the battery separator, and then pour out the excess acid solution Put it into a collection container, weigh it accurately, and calculate the weight difference between the acid solution before and after, to obtain the acid absorption amount of the battery separa...
