The appearance of the waste lead-acid storage battery is damaged to a certain degree, and a repair technology for repairing the appearance of the waste lead-acid storage battery is needed.
Disclosure of Invention
The invention aims to: the method for restoring the appearance of the waste lead-acid storage battery is provided, and the problem that the appearance of the waste lead-acid storage battery is damaged to a certain degree and a restoration technology is needed to restore the appearance of the waste lead-acid storage battery is solved.
The technical scheme adopted by the invention is as follows:
a method for recovering the appearance of a waste lead-acid battery comprises the following steps:
s1: cleaning dust on the outer surface of the waste lead-acid battery, and naturally drying the waste lead-acid battery in a ventilated place for later use;
s2: preparing cyclohexanone 80 and turpentine 20, and mixing with medicinal liquid of 1-2-dichloroethane to mix uniformly;
s3: placing the waste lead-acid battery dried in the step S1 into the liquid medicine mixed in the step S2 and staying for 2-5 seconds in winter; stay for 1-3 seconds in summer
S4: and taking out the battery, and putting the battery on an airing rack for airing.
The lead-acid storage battery shell is mainly made of ABS (acrylonitrile butadiene styrene), the automobile is made of PP (polypropylene), a plastic sealing cover which can be unscrewed is arranged at the top of the lead-acid storage battery shell, a vent hole is arranged on the plastic sealing cover, the ABS and PP plastics are terpolymer of three monomers of acrylonitrile (A), butadiene (B) and styrene (S), the relative contents of the three monomers can be changed at will to prepare various resins, the characteristics that the ABS plastics are dissolved in cyclohexanone are utilized, according to the actual proportion, the cyclohexanone 80 and the turpentine 20 are prepared and mixed with the liquid medicine of 1-2-dichloroethane to be prepared uniformly, so that the ABS and PP plastics are dissolved in the prepared liquid medicine, dust on the surface is cleaned and then put into the liquid medicine to dissolve the lead-acid storage battery shell, the dust is remained for 2-5 seconds in winter, and remained for 1-3 seconds in summer to ensure that the lead-acid storage battery shell, and the surface of the waste lead-acid battery can be damaged after being dried, and the surface of the waste lead-acid battery can be recovered.
Further, in step S1, the used lead-acid battery has printed characters on its surface, and the original printed characters are washed away after the surface dust of the used lead-acid battery is cleaned.
The printing contains other ink, resin, or the like, and is washed away to prevent the reaction with the chemical solution in step S2.
Further, in the step S1, the air drying time is 6 hours in summer and 12 hours in winter.
The air drying time is about 6 hours in summer and about 12 hours in winter according to experiments because the temperature and the air volume are different between summer and winter.
Further, when the battery is dried in the step S4, the area of the battery contacting the drying rack is minimized.
In step S4, since a certain amount of liquid medicine adheres to the outer surface of the waste lead-acid battery when the battery is taken out of the liquid medicine, and the contact surface of the waste lead-acid battery may change due to reaction with the drying rack in contact with the waste lead-acid battery, we should try to ensure that the area of the lead-acid battery in contact with the drying rack is the minimum.
Further, in the step S3, when the waste lead-acid battery is placed in the liquid medicine, the plastic sealing cover and the vent hole at the top end of the waste lead-acid battery are not immersed in the liquid medicine, and the other parts are immersed in the liquid medicine.
The lead-acid accumulator of general lead-acid battery has a plastic sealing cover on its top, which can be unscrewed and has a ventilation hole. These are used for filling pure water, checking an electrolyte and discharging gas. Therefore, when the waste lead-acid battery is put into the liquid medicine, the plastic sealing cover and the vent hole at the top end of the waste lead-acid battery are ensured not to be immersed into the liquid medicine, and other parts are immersed into the liquid medicine. So that the liquid medicine does not enter the electrolyte inside.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. the invention provides a method for recovering the appearance of a waste lead-acid battery, which solves the problem that the waste lead-acid battery can be damaged to a certain extent on the outer surface thereof and can be recovered;
2. the invention provides a method for recovering the appearance of a waste lead-acid battery, which can only repair the damage of the appearance of the lead-acid battery without damaging the internal electrolyte of the lead-acid battery.
