2. Feature description
2.1 Specific gravity 1.0-1.6g/ml belongs to heavy zinc oxide.
2.2 Adding zinc oxide to different types of glass can make the glass produce some special properties. For example, replacing 5% of silicon dioxide with zinc oxide in photosensitive glass and photosensitive ceramics can significantly reduce its thermal expansion coefficient and increase light sensitivity and light density by nearly 20 times. Adding zinc oxide to optical glass can make the glass have high refractive index, absorb ultraviolet rays and transmit light. Zinc oxide imparts a range of electrical and semiconducting properties to electrical glass, allowing it to be used in printed circuits, capacitors, resistors and conductive articles.
2.3 Zinc oxide was used earlier in the transparent coarse glaze of handicrafts or tableware and the translucent glaze of coarse ceramics.
2.4 Zinc oxide for ceramic glass bulbs not only meets the needs of the industry in terms of chemical indicators, but also undergoes special treatment in terms of physical properties, increasing the specific gravity, reducing the coefficient of thermal expansion, and avoiding glaze shrinkage and cracking caused by zinc oxide.
3. Packaging
Packed in plastic woven bags lined with polyethylene plastic bags, with a net weight of 25kg or 50kg per bag. It should be stored in a dry warehouse, and should be protected from rain and kept dry during transportation.
