Problems solved by technology

However, after mechanical separation, the glass will be damaged and scrapped, and the solidified glue is likely to remain on the aluminum substrate, and it is necessary to manually use a blade to remove the glue, which is difficult, time-consuming and inefficient, and is likely to cause the substrate bumps and scratches

Abstract

The invention provides a glue removing agent. The glue removing agent comprises the following components in parts by weight: 280-500 parts of an alcohol solvent, 1.5-2 parts of an auxiliary agent, 220-280 parts of a humectant and the balance water. The invention also provides an application method of the glue removing agent. According to the glue removing agent and the application method thereof,glue removal can be effectively carried out on base materials, the glue removal efficiency is high, and damages on base materials are not easily caused.

Description

technical field [0001] The invention relates to a glue remover and an application method of the glue remover. Background technique [0002] In recent years, in the production or assembly process of 3C products (such as mobile phones, tablet computers or notebook computers, etc.), it is often necessary to combine workpieces with adhesives. For example, glass and metal substrates are bonded by adhesives. However, if the product needs to be reprocessed in case of defective products during the production or assembly process, it is usually necessary to remove the adhesive to separate the bonded workpieces. At present, the mechanical separation method is mostly used to remove the adhesive between the glass and the aluminum substrate, that is, the mechanical pressing force is used to forcibly separate the glass and the aluminum substrate. However, after mechanical separation, the glass will be damaged and scrapped, and the solidified glue is likely to remain on the aluminum subst...
