Preprocessing method of discarded PC boards for secondary utilization

Abstract

The invention relates to a preprocessing method of discarded PC boards for secondary utilization. A device comprises a workbench, a fixing mechanism, a water tank and a scrubbing mechanism, wherein the upper end surface of the workbench is provided with the fixing mechanism and the water tank; and the scrubbing mechanism is arranged in the water tank. Through a width adjusting group and a clamping group in the fixing mechanism, the distance between fixing plates can be adjusted according to the sizes of the discarded PC boards, so that the clamping requirements of the discarded PC boards of different sizes are met, the surfaces of the discarded PC boards can be effectively cleaned conveniently, and the cleaning effect on the discarded PC boards is improved; furthermore, multiple discarded PC boards can be cleaned at the same time, so that the cleaning efficiency of the discarded PC boards is improved; and a sponge wiper in the scrubbing mechanism is used for wiping and cleaning the surfaces of the discarded PC boards when the discarded PC boards move up and down, so that the cleaning effect on the surfaces of the discarded PC boards is improved.

Description

technical field [0001] The invention relates to the technical field of secondary utilization pretreatment processing of waste PC boards, in particular to a secondary utilization pretreatment processing method of waste PC boards. Background technique [0002] PC sheet is also called polycarbonate sheet, Kapron sheet, is an engineering plastic with excellent comprehensive performance, has outstanding physical, mechanical, electrical and thermal properties, it is called "the king of transparent plastics", PC sheet is divided into It is a hollow board series (also known as Kabulon, unbreakable glass) and a solid board series (also known as endurance board, transparent steel board), both of which have the advantages of light transmission, UV protection, flame retardancy, and weather resistance, and are widely used in public, Lighting and rain shelters for civil buildings, passage roofs, sound insulation walls for elevated roads, shopping mall roofs, and plant greenhouses are curr...

AI Technical Summary

Problems solved by technology

[0003] 1. In the process of cleaning waste PC boards, the four corners of the waste PC boards cannot be clamped and fixed accurately according to the size of the waste PC boards, so that when cleaning waste PC boards of different sizes, the effective cleaning effect cannot be achieved , and only one waste PC board is cleaned, which reduces the cleaning efficiency of waste PC boards;

[0004] 2. When cleaning the waste PC board, the surface of the waste PC board is mostly cleaned by spraying. The spray cleaning can only be used to clean the waste PC board, resulting in impurities remaining on the waste PC board.
