Conductive silver glue recycling_ Silver glue recycling_ Precious metal recycling manufacturers

Conductive silver glue is a kind of colloidal material with conductive properties, which is usually composed of conductive particles (such as Silver nanoparticle) and organic matrix. It has excellent conductivity and good adhesion, and is widely used in the fields of electronics, electrical appliances, and optoelectronics. Such as quartz crystal, infrared pyroelectric detector, piezoelectric ceramic, Potentiometer, flash lamp, shielding, circuit repair, etc., can also be used for conductive bonding in the radio instrument industry; It can also replace solder paste to achieve conductive bonding.

The preparation process of conductive silver adhesive is relatively simple and generally includes the following steps: 1. Material preparation: Firstly, conductive particles and organic matrix need to be prepared. Conductive particles are usually Silver nanoparticle, which have high conductivity and large specific surface area. Organic matrices can choose suitable polymers, such as acrylic acid, polyvinyl alcohol, etc. 2. Disperse conductive particles: Disperse conductive particles in an appropriate solvent to form a suspension. During the dispersion process, some dispersants are usually needed to prevent particle aggregation. 3. Preparation of matrix: Mix the organic matrix with an appropriate amount of solvent to form a uniform matrix liquid. This matrix liquid will provide the basic structure of conductive silver glue. 4. Mixing conductive particles and matrix: Gradually add the suspension of conductive particles to the matrix liquid, and perform stirring or ultrasonic treatment to evenly disperse the conductive particles in the matrix. This process requires controlling the concentration of particles to ensure that the final prepared conductive silver adhesive has appropriate conductivity. 5. Solvent removal: The mixed conductive silver gel solution is subjected to solvent removal treatment, usually by heating, vacuum adsorption, or other appropriate methods to evaporate or evaporate the solvent. 6. Performance adjustment: Further adjustments can be made to the conductive silver adhesive according to specific needs. For example, some crosslinking agents can be added to improve the mechanical strength and stability of conductive silver adhesive.
