Abstract

OCR 09WP 26 / 11 / 2568 A method for separating the surface material of solar panels using a fine grinding process, employing an air-based system for product separation. With its specific gravity, this method allows for the recycling of the resulting product, representing an innovative approach to separating the surface materials of solar panels. Sunlight is used in the process of fine grinding and separating the resulting powder product using the specific gravity of the substance. The air system uses compressed air to disperse metal molecules and induce electrical conductivity, resulting in highly accurate metal powder separation. Products from the recycling process of expired / deteriorated / no longer cost-effective solar panels for electricity generation. This is considered a new process that has not been used before in Thailand, according to the circular economy model. For the protection of the environment, to reduce global warming, and to utilize existing resources. High value: By utilizing the specific gravity of substances, valuable metal products can be obtained, such as copper powder and zinc powder. Plastic and glass powders, which are important metals, are scarce and have high economic value and are crucial to... Basic industries

Claims

OCR 09WP 12 / 01 / 2569 1. Method for separating the surface material of solar panels using a fine grinding process with an air system and separating the finished product. The specific gravity for product recycling (Circular Economy) involves the following steps: Step 1: Disassembling the solar panel, starting with the junction box. And the aluminum frame is removed from the solar panel. Step 2 involves separating the coated glass panels through a crushing process to detach the glass panels from the base. The back sheet is the product of this process; it is glass powder. Step 3: Metal separation process on the back sheet, followed by coarse grinding to reduce size. The process of grinding into powder. Step 4: Metal Powder Separation. The collected metal powder is passed through a metal trap for further sorting. Based on specific gravity, the metal powder is processed to obtain silicon and copper powder. All remaining metal powder is then transported further. An electrostatic separator is used to separate metal powders with different electrical conductivity properties, resulting in... Copper powder, silicon powder, and plastic alloy powder.

2. Method for separating the surface material of solar panels using a fine grinding process with an air system and product separation. Specific gravity and electrostatic separators yield metal powder for recycling, as per the following points. Rights 1 are held in which the metal powder separation process utilizes a pneumatic system and an electrical induction system. (Electrostatic Induction) in the management of metal powder sorting.
