Enameled flat wire refers to the heterosexual metal wire with approximately rounded rectangular cross section, the thickness is from 0.025mm to 2mm, and the width is generally less than 5mm. Its width to thickness ratio varies from 2:1 to 50:1. Because the flat filament is shaped like a ribbon, it is sometimes called an ultra-narrow flat ribbon. Compared with the common round wire, the flat wire has unique advantages in heat dissipation, welding contact area, fatigue resistance, hardness control, etc.
What are the process characteristics of polyvinyl acetal enameled flat wire?
What are the properties of polyvinyl acetal enameled flat wire?
What are the relevant parameters of polyvinyl acetal enameled flat wire?
Acetal paint is divided into two types: large wire paint and small wire paint. The large wire paint has a higher viscosity than various enameled wire paints and is suitable for painting on vertical cars using the mold method, while the fine wire paint has a lower viscosity and is suitable for It is produced by the felt method on a horizontal enameling machine. The production practice of applying large wire paint over the years has created a lot of experience using the mold method, which has many characteristics:
1. When using the mold method to coat the wire, when the hole diameter of the mold is properly matched, the thickness of the paint layer of the polyvinyl acetal enameled flat wire can be kept stable for a long time, and there is no need to adjust the thickness as often as the felt method.
2. The surface of the enameled wire can be kept uniform and smooth, and there are few defects such as light, bubbles and particles. Under the condition that furnace temperature, speed and copper wire quality are basically stable, it has a higher genuine product rate than other types of polyvinyl acetal enameled flat wire.
3. When the mold method is used to coat the line, the original paint can be used, and the solid content of the coating line can be increased, which can not only save the solvent, but also reduce the paint adjustment process.
Polyvinyl acetal enameled flat wire is the earliest high-strength enameled wire, which has high mechanical strength and can meet the requirements of general high-speed automatic winding devices on the strength of enameled wire; in addition, its paint film is softer and has good adhesion to copper wire. , so it can also meet the requirements of micro-motor end shaping. But the biggest feature of polyvinyl acetal enameled flat wire is its excellent oil resistance and thermal shock resistance.
Thermal grade 180 The polyvinyl acetal enameled flat wire has good thermal shock resistance, high softening breakdown temperature, excellent mechanical strength, good solvent resistance and refrigerant resistance, and its weakness is that it is easy to hydrolyze under closed conditions. The wire is widely used in the windings of motors, electrical appliances, instruments, electric tools and power dry-type presses with high heat resistance requirements.
Now Baiwei Electric has six product categories: enameled copper &aluminum flat wire, enameled copper (aluminum) round wire, composite wire, transposed wire(CTC), paper covered flat wire and non woven fabric filmwrapped flat copper & aluminum wire.
