Silver paste It is a type of pigment that is applied in various places. So, what are the methods for using and storing silver paste?

　　The commonly used silver paste contains volatile substances such as mineral oil and various additives to enhance the stability and dispersion of the silver paste. Therefore, when storing the silver paste, it must be sealed. For example, conductive silver paste and aluminum silver paste must be sealed. If each product is opened and not fully used, it must be sealed immediately. Otherwise, after prolonged contact with the air, it may undergo drying and oxidation, resulting in uneven dispersion of the silver paste, small particles, and blackening.

　　Under normal circumstances, well-sealed silver paste can be used for more than a year. The most important step in using silver paste is dispersion. Usually, we disperse the silver paste in some solvents. If some wetting agents can be added and it is soaked for a while, then slowly stirred to make it into a uniform liquid, and then added to the pre-prepared coating, it can achieve the best usage effect. When dispersing the silver paste, high shear force stirring must not be used, as it will cause the thin aluminum plate to deform and affect the appearance effect. Therefore, a slow stirring method must be used. If the acid value of the coating is too high, it will reduce the stability of the coating's preservation and cause the coating to turn black and thicken. Why recycle conductive silver paste? Are there any benefits? Palladium-carbon catalyst recycling. Now let's briefly understand these silver tips, hoping to be helpful to everyone. The role of solvents in conductive silver paste is to dissolve resins, allowing conductive particles to be fully dispersed in the polymer; adjusting the viscosity and viscosity stability of the conductive paste; determining the drying speed; improving the surface condition of the substrate, so that the paste has good adhesion performance with the substrate. The solubility and polarity of solvents in conductive silver paste are important parameters for selecting solvents. This is because solvents have a significant impact on printing adaptability and substrate bonding and curing.

　　In addition, the boiling point of the solvent, the magnitude of its saturated vapor pressure, and the toxicity of the palladium-carbon catalyst recovery to the human body are all factors that should be considered. The boiling point and saturated vapor pressure of the solvent are closely related to the stability of the printing materials and the durability of the operation. It has a decisive influence on the temperature and rate of heating and curing. Generally, high-boiling-point solvents are used, such as BCA (acetic anhydride), diethylene glycol butyl ether acetate, diethylene glycol ether acetate, isophorone, etc. The additives in the conductive silver paste mainly include dispersants, leveling agents, oxygen protectants, and metal particle stabilizers for the conductive silver paste.
