Controlling the purity of cut-resistant tungsten wire is a key step to ensure the performance and quality of tungsten wire. The following are some of the main methods to control the purity of cut-resistant tungsten wire:
- Raw material selection
High-purity tungsten powder: Select tungsten powder with a purity higher than 99.95% as raw material. High-purity tungsten powder can reduce the impact of impurities on the performance of tungsten wire and improve the purity and cutting resistance of tungsten wire.
Impurity detection: Strict impurity detection is carried out before the raw materials are put into storage to ensure that the tungsten powder does not contain harmful impurities, such as metal elements such as iron, copper, nickel, and non-metallic elements such as carbon and oxygen.
- Production process control
Closed environment: During the entire production process, the closedness and cleanliness of the production environment are maintained to reduce the contamination of tungsten wire by external impurities.
Precise control of process parameters: In key process links such as pressing, sintering and wire drawing, precise control of process parameters such as temperature, pressure, time, etc., to ensure that the tungsten wire is not contaminated or oxidized during the forming process.
Use high-quality molds: Use high-quality, pollution-free molds for pressing and drawing to avoid impurities in the mold from contaminating the tungsten wire.
III. Quality inspection and screening
Purity inspection: Use high-precision detection methods such as spectral analysis and chemical analysis to regularly detect the purity of tungsten wire to ensure that the purity of tungsten wire meets the standard requirements.
Surface quality inspection: Use microscopes, magnifying glasses and other tools to carefully inspect the surface of tungsten wire to observe whether there are impurities, cracks, shrinkage holes and other defects.
Screening and grading: Screen and grade tungsten wire according to the test results, and remove tungsten wire with substandard purity or defects from the production process.
- Storage and packaging
Vacuum or inert gas packaging: Use vacuum packaging or inert gas (such as argon) packaging to prevent tungsten wire from being oxidized or contaminated during storage and transportation.
Dry storage environment: Store tungsten wire in a dry, dust-free, non-corrosive environment to avoid the influence of humidity and corrosive gases on tungsten wire.
- Continuous improvement and technological innovation
Develop new technologies: Continuously develop new production technologies and processes to improve the purity and performance of tungsten wire.
Introduce advanced equipment: Introduce high-precision and high-efficiency production equipment and testing equipment to improve the automation and detection accuracy of the production process.
Employee training and skill improvement: Strengthen employee training on production technology and quality control, and improve employees’ skill level and quality awareness.
