Problems solved by technology

[0003]However, cast iron and lead-based alloys are easy to bond, so cork powder is often sprayed on the inner wall of the mold cavity to prevent the lead-based alloy from adhering to the inner wall of the mold cavity However, the setting of cork powder makes the cooling rate of the lead-based alloy slow, resulting in low production efficiency; at the same time, the setting of cork powder makes the surface of the grid plate made rough and the density distribution uneven, resulting in low quality of the grid plate made; The powder is easy to fall off and burnt, resulting in unstable dimensions of the prepared grid

Abstract

The invention relates to the field of storage batteries, in particular to a grid plate preparation method. The method is implemented by a technical scheme that the grid plate method comprises the following steps in turn: (1) preparing a molten lead-based alloy; (2) pouring the molten lead-based alloy obtained by the step (1) into a mould cavity of a nickel-based alloy grid plate mould; (3) cooling the mould by using gasified water; and (4) removing the mould. The method is mainly used for preparing grid plates of storage batteries.

Description

technical field [0001] The invention relates to the field of accumulators, in particular to a grid plate preparation method. Background technique [0002] For example, Chinese Patent No. 00109617.6 discloses a lead-acid storage battery grid, and the grid mold used in its preparation process is often a cast iron grid mold. [0003] However, cast iron and lead-based alloys are easy to bond. Therefore, cork powder is often sprayed on the inner wall of the mold cavity to prevent the lead-based alloy from adhering to the inner wall of the mold cavity. However, the setting of the cork powder makes the cooling rate of the lead-based alloy slow. Resulting in low production efficiency; at the same time, the setting of cork powder makes the surface of the prepared grid plate rough and the density distribution is uneven, resulting in low quality of the prepared grid plate; meanwhile, the cork powder is easy to fall off and burn, resulting in the size of the prepared grid plate being di...
