Product Information
- The melting point of zinc is 419.5°C. At room temperature, it is brittle; at 100-150℃, it becomes soft; when it exceeds 200℃, it becomes brittle.
- The chemical properties of zinc are active. In the air at room temperature, a thin and dense basic zinc carbonate film is formed on the surface to prevent further oxidation. When the temperature reaches 225°C, zinc oxidation is intense. When it burns, it emits a blue-green flame.
- It is suitable for the materials of instrument parts and instrument shells and coins. At the same time, zinc itself and other metals will not cause sparks, so it is suitable for underground explosion-proof equipment. It is widely used in rubber, paint, enamel, medicine, printing, fiber and other industries. Zinc has suitable chemical properties.
