And further, reaming the sand hole in the vertical direction.
Further, the diameter of the plastic particles is selected to be 1.2-2mm.
Further, the plastic particles and the storage battery are to be repaired to have the same color.
Further, after the repaired storage battery is subjected to inflation pressurization detection and qualified detection, the storage battery is polished by using a goat hair brush, and then is wiped by using a diluent after being polished.
Further, the diluent adopts a polyvinyl chloride retarder solvent.
Further, the metal rod is made of corrosion-resistant stainless steel.
The beneficial effect of the invention is that,
the hole enlargement is carried out to sand hole department, conveniently restores, and the reaming after recycling chloroform to plastic pellet and melting is in inserting plastic pellet and repairs, because plastic pellet and reaming department all have taken place the melting for both can be better adhere and restore, utilize the volatility of chloroform, can be quick obtain the battery case after repairing.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention.
A method for repairing sand holes on the shell of a storage battery comprises the following steps,
s1, inflating and pressurizing a storage battery to be repaired by 50-80kpa, and marking a sand hole air leakage position by using a marking pen;
specifically, a marker pen with a color different from that of the leaking position is generally used to mark the leaking position for easy identification.
S2, placing the sand hole face upwards, using a drilling machine to expand the hole of the sand hole, and selecting plastic particles which have the diameter of 0.01-0.02mm and are same as the battery shell in material and color after expanding the hole;
specifically, after a liquid leakage position is confirmed, a liquid pumping device is needed to be used for pumping acid liquid in the storage battery, the sand hole position of the storage battery is placed upwards after the acid liquid is pumped out, a bench drill or a pistol drill is used for reaming in the vertical direction by using a drill bit of 1.5mm, the sand hole position is ensured to be enlarged, plastic particles which are 1.7mm in length and the same as the position to be repaired and have the same color are selected after the reaming is finished, and the length of the particles is generally 3-5mm.
S3, placing the selected plastic particles into 100ml of trichloromethane for soaking for 5-10min, and dipping the trichloromethane on the inner wall of the hole expansion part by using a metal rod for 1-3min;
