●Zinc is a bluish white metal. A density of 7.14 g/cm³, a melting point of 419.5 °C. Brittle at room temperature; 100 ~ 150 °C, are softened; exceed 200 °C, they become brittle.
●The chemical properties of zinc are active. In the air at room temperature, a thin and dense alkaline zinc carbonate film forms on the surface to prevent further oxidation. When the temperature reaches 225°C, zinc oxidation is intense. When it burns, it emits a teal flame.
●It applies to the materials of instrument parts as well as instrument trays and coins. At the same time, zinc itself and other metals do not cause sparks, making it suitable for underground explosion-proof devices. It is widely used in rubber, varnish, enamel, medical, printing, fiber and other industries.
