Preparation method for recycling and reusing waste hardware

Abstract

The invention discloses a preparation method for recycling and reusing waste hardware. The method comprises the following steps that 1, the recovered hardware is cleaned with clear water, and put intoan ultrasonic cleaning device, a proper amount of a cleaning agent is properly added, and the hardware is subject to ultrasonic cleaning; 2, the cleaned hardware is put into an acid washing agent forsoaking; 3, the surface of the acid-washed hardware is removed by using a nylon brush; and 4, the hardware is screened. According to the method, the hardware is subjected to a series of treatment, sothat oil stains, rust and other impurities on the surface of the hardware can be effectively removed. The cleaning agent has a r good oil removal effect and is small in corrosion to the surface of the hardware, and the environment pollution is small. According to the method, the acid washing agent used in the method is good in stability and long in corrosion inhibition effect lasting time, the surface of the cleaned hardware is smooth and clean, residues on the surface of the hardware can be effectively removed, rusting and the like are achieved, and the acid washing effect is good, the hardware is screened and selectively treated after being cleaned, and the utilization rate of the hardware is greatly improved.

Description

Technical field [0001] The invention relates to the field of environmental protection, in particular to a preparation method for recycling and reusing waste hardware. Background technique [0002] Hardware refers to tools obtained through processing and casting of metals such as gold, silver, copper, iron, tin, etc., which are used to fix things, process things, decorate, etc., and can be processed into knives, swords and other artworks or metals. Device. In modern society, hardware is more extensive. For example, hardware products such as hardware tools, hardware parts, household hardware, construction hardware, and security products are mostly not final consumer goods. [0003] Hardware is widely used in daily life, and the hardware can be recycled and reused, which is of great significance to sustainable development. Nowadays, hardware parts have a limited service life. After a period of time, they will fail and are often discarded. If people leave it on the ground, it will ca...

Problems solved by technology

Nowadays, the service life of hardware is limited, and it will break down after a period of time, and it is often discarded by people. If people leave it on the land, it will cause soil metal pollution and damage the environment, so it is necessary to recycle metal parts , After recycling, post-processing is required to reuse

The existing hardware recycling methods have the disadvantages of cumbersome operation, time-consuming and laborious, and poor recycling and processing effects, and the recycling and processing effects are poor
