A potentiometer is an adjustable electronic component widely used in electronic equipment. Base metal glass glaze resistor slurry is an important material in potentiometer manufacturing, and its performance directly affects the quality and stability of the potentiometer.

This article will introduce in detail the manufacturing method of base metal glass glaze resistor slurry for potentiometers, including raw material selection, batching, mixing, grinding, modulation, filtration, inspection and packaging.

Raw material selection

1. Base metal powder: Choose base metal powder with high purity, uniform particle size and stable resistivity, such as nickel, chromium, copper, etc. These metals have good electrical conductivity and stability and can meet the requirements of potentiometers.
2. Glass glaze: Glass glaze is an inorganic non-metallic material with high temperature stability, chemical stability and good insulation properties. To select a glass glaze suitable for potentiometers, it is required that its composition has good compatibility with the base metal powder and can form a dense resistive film during the sintering process.
3. Organic carrier: Organic carrier is an important component of resistor slurry, which plays the role of dispersing metal powder and glass glaze and adjusting the viscosity of the slurry. Choose organic carriers with moderate volatility and good environmental performance, such as terpineol, butyl carbitol, etc.

Ingredients

Base metal powder, glass glaze and organic carrier are mixed according to a certain proportion. The proportion of ingredients is adjusted according to the performance requirements and manufacturing process of the potentiometer.

Generally speaking, the higher the content of base metal powder, the lower the resistivity; the higher the content of glass glaze, the higher the resistivity.

mix

Put the prepared raw materials into the mixing equipment and mix them so that the base metal powder, glass glaze and organic carrier are fully and evenly mixed together. The mixing time and speed should be moderate to avoid agglomeration of metal powder and excessively large glass glaze particles.

Grind

The mixed slurry needs to be ground to reduce the particle size and improve the fineness and uniformity of the slurry. Grinding equipment can use ball mills, sand mills, etc. During the grinding process, the grinding time and the type and quantity of grinding media should be controlled to avoid excessive grinding that will lead to a decrease in slurry performance.

modulation

The ground slurry needs to be modulated to adjust the viscosity and fluidity of the slurry. Appropriate amounts of diluents, thickeners and other auxiliary materials can be added during the preparation process. The prepared slurry should have good brushability and adhesion to form a uniform resistance film on the potentiometer substrate.

filter

The prepared slurry needs to be filtered to remove impurities and particles. Filtration equipment can use wire mesh filters, filter cloth filters, etc. The filtered slurry should be clean and free of impurities to ensure the quality and stability of the potentiometer.

test

Conduct quality inspection on the filtered slurry, including appearance, viscosity, fineness, solid content, resistivity and other indicators. Only the slurry that has passed the inspection can be packaged and used. Unqualified slurry needs to readjust the proportion of ingredients or undergo other processing until it meets the quality requirements.

Package

The slurry that has passed the inspection should be packaged in containers with good sealing, corrosion resistance, non-toxic and odorless packaging materials. During the packaging process, long-term contact between the slurry and the air should be avoided to avoid volatilization of the organic carriers in the slurry causing performance changes. The packaged slurry should be marked with product name, batch number, production date and other information to facilitate traceability and management.

Summary and Outlook

This article introduces in detail the manufacturing method of base metal glass glaze resistor slurry for potentiometers, including the steps of raw material selection, batching, mixing, grinding, modulation, filtration, inspection and packaging. These steps are of great significance to ensure the quality and stability of the potentiometer.

In the future, with the advancement of science and technology and the development of the market, the performance requirements for base metal glass glaze resistor slurries used for potentiometers will become higher and higher, and the manufacturing methods will also be continuously optimized and improved.

By adopting new raw materials, optimizing process flow, improving automation and other measures, more efficient, environmentally friendly and more stable manufacturing of base metal glass glaze resistor slurries for potentiometers can be achieved.

What are the main factors of the temperature resistance of the patch

The temperature resistance of the patch inductor mainly depends on the following factors:

1. The quality of raw materials: High -quality raw materials have better stability and reliability, and can effectively extend the life of the inductance. For example, a magnetic core material with high magnetic guidance, low magnetic damage, and coil wires with high temperature resistance and low impedance.
2. Structural design: By optimizing the structural design of the inductance, the heat loss of the inductance can effectively reduce the heat loss of the inductance in high temperature, thereby improving the temperature resistance. For example, measures such as optimizing coil winding and increasing the cross -area of the coil can improve the thermal performance and reliability of the inductance.
3. Heating design: In order to prevent inductance from overheating in high temperature environments, the heat dissipation design of inductance needs to be strengthened. For example, increased heat dissipation pieces and selection of materials with good thermal conductivity can improve the heat dissipation performance and temperature resistance of inductance.
4. Production process: In the process of inductance, the production process must be strictly controlled to ensure the quality of the inductance, and the temperature resistance of temperature resistance is reduced due to the problem of production technology. For example, strictly control the winding process of the coil and the assembly process of magnetic cores.

In summary, the temperature resistance of improving the inductance of the patch needs to be started from choosing high -quality raw materials, optimizing structural design, strengthening heat dissipation design, and strict control of production technology.

At the same time, in practical applications, we should also pay attention to compliance with the use specifications and precautions to ensure that the temperature resistance of the patch is fully guaranteed.
