Filament manufacturing process

Abstract

The invention discloses a filament manufacturing process, which is characterized in that a coating material is sprayed on the surface of a filament by adopting a thermal spraying process, and then thefilament is placed in a vacuum environment for drying, wherein the coating material is a polyester epoxy powder coating or a pure polyester epoxy powder coating. The filament manufactured according to the filament manufacturing process provided by the invention can bear high-strength current, so that the service life of the filament is enabled to achieve an expected effect, and the service life is longer.

Description

Technical field [0001] The invention relates to ceramic materials, in particular to a manufacturing process of a filament. Background technique [0002] "Lighting appliances" are produced with the continuous development of human civilization. The most common function of light bulbs is lighting. The light bulb appeared as early as 1854. However, with the promotion of the concept of environmental protection, the emergence of energy-saving lamps gradually occupy the bulb market and become the mainstream. However, light bulbs are still needed in some special fields, such as spectrum analyzers and artistic lighting. However, the filament of the light bulb is prone to burnout due to the need to withstand the flow of high-intensity current, which causes it to fail to reach the expected lifespan. Therefore, the ability of the filament in the bulb to withstand the current intensity affects the life of the bulb. Summary of the invention [0003] The purpose of the present invention is ...

AI Technical Summary

Problems solved by technology

However, because the filament of the bulb needs to withstand the flow of high-intensity current, it is prone to problems such as blown out, which makes it unable to achieve the expected service life.
