When using tungsten wire for glass heating, the following specifications must be followed to ensure safety and efficiency: 1. Material selection: 1.1 Use high-purity tungsten wire (purity ≥99.95%) to ensure oxidation resistance and mechanical strength at high temperatures. 1.2 According to the heating temperature and glass type, select tungsten wire of appropriate diameter to avoid overheating or breakage. 2. Working environment: 2.1 Tungsten wire is easy to react with oxygen at high temperatures and needs to be used in a…
