The manufacturing method
of aluminum silver paste
1. Introduction
aluminum silver paste is an important raw material for the production of chemical products, widely used in coatings, inks, plastics and other fields, because of its excellent metallic luster and hiding power, can give products good appearance effect. This article will introduce the manufacturing method of aluminum silver paste in detail, including raw material preparation, production process, product quality control and so on.
2. Raw material preparation
1. Aluminum powder: Select aluminum powder with high purity and suitable particle size as raw material to ensure its good activity and dispersibility.
2. Solvent: Choose solvents with good compatibility with aluminum powder and moderate volatility, such as alcohols, esters, etc.
3. Additives: According to actual needs, additives such as dispersants, wetting agents and stabilizers can be selected to improve the stability and dispersion of aluminum silver paste.
3. production process
1. ingredients: according to a certain proportion of aluminum powder, solvents and additives into the high-speed dispersion equipment.
2. Dispersion: In a high-speed dispersion device, the mixture is fully stirred and dispersed to uniformly disperse the aluminum powder in the solvent to form a stable slurry.
3. Grinding: The slurry is sent to grinding equipment such as sand mill or bead mill to further refine and improve the fineness and gloss of aluminum silver paste.
4. Filtration: Remove impurities and coarse particles in the slurry through filtration equipment to ensure product quality.
5. Packaging: Put the filtered aluminum silver paste into a sealed container for packaging.
4. product quality control
1. detection of physical properties: the fineness of aluminum silver paste, viscosity, metallic luster and other physical properties are tested to ensure that it meets the relevant standards.
2. Chemical analysis: chemical analysis of the composition of aluminum silver paste to ensure that the content of each component is within the specified range.
3. Stability test: The long-term storage stability test of aluminum silver paste is carried out to observe whether there is delamination, precipitation and other phenomena to ensure product quality.
Precautions for
5.
1. In the production process, the operating conditions of each process should be strictly controlled to ensure stable product quality.
2. For different types of aluminum silver paste, the production process and formula should be adjusted according to actual needs to meet the application requirements of different fields.
3. During storage and use, attention should be paid to maintaining sealing, drying, and avoiding light conditions to prevent the performance of aluminum silver paste from being affected.
6. Conclusion The manufacturing method of
aluminum silver paste involves the control of multiple links and process parameters. In order to ensure product quality, it is necessary to consider the raw material preparation, production process, product quality control and so on. Through the manufacturing method introduced in this paper, aluminum silver paste with high metallic luster, good dispersion and stability can be produced to meet the application requirements of different fields.
