Physical and Chemical Properties | Properties zinc is a blue-white metal (closely packed hexagonal system). melting point 419.58 ℃ boiling point 907 ℃ relative density 7.14 solubility soluble in inorganic acid, alkali, acetic acid, insoluble in water. Zinc is a blue-white metal (tightly packed hexagonal system). Melting point 419.58 °c, boiling point 907 °c. The relative density was 7.14. The particle structure of the zinc powder pigment is granular and flaky, and the flaky zinc powder has great hiding power. There is a relatively high corrosion resistance in the atmosphere, but no corrosion resistance in acid salts and basic salts. Soluble in inorganic acid, alkali, acetic acid, insoluble in water. |
Use | For the production of anti-rust paint and powder, bleached grease, reduced indigo dyes, etc. is mainly used for anti-corrosion coatings. In addition, it is also used in dye, metallurgy, chemical and pharmaceutical industries. |

Zinc is a blue-white metal (tightly packed hexagonal system). The powder was a light gray fine powder. Melting point 419. 58 °c. Boiling point 907 °c. The relative density was 7.14. The vapor pressure was 0. 13kPa( 487 ℃). Soluble in inorganic acid, alkali, acetic acid, insoluble in water.
using metallic zinc as raw material, after distillation and purification, impurities were removed to obtain refined solution, and metal zinc powder was prepared by spray drying.
superfine zinc powder is mainly used as the key raw material of zinc-rich coatings and other high-performance coatings such as anti-corrosion and environmental protection, and is widely used in large steel components, ships, containers, aviation, automobile and other industries, ordinary zinc powder is widely used in metallurgy, chemical industry, pharmaceuticals, dyes, batteries, etc.
Industry. As a pigment, the hiding power is extremely strong. Has a good anti-rust and resistance to atmospheric erosion. Commonly used in the manufacture of anti-rust paint, strong reducing agent, battery, etc.
wet flammable articles. Risk code: GB Class 4.3 Port 43014, UN N0.1436; IMDG Code page 4373, Class 4.3. Spontaneous ignition point 460. The explosion limit is above 500g/m3. Dust and air can form an explosive mixture, which is easy to be ignited by open flame and cause explosion. Wet dust is easy to burn Fever in the air. Contact with water, acids or alkali metal hydroxides can emit flammable hydrogen gas. Reaction with oxidizing agents, sulfur can cause ignition or explosion. Mouse abdominal LD50: 15mg/kg. Dust can irritate eyes, skin and respiratory system, inhalation
Can cause Cough, low-grade fever. Skin contact with zinc powder, moisture absorption Fever, can cause burns. Packed with an iron drum lined with a polyethylene plastic bag, the mouth of the bag is tightly tied with a rope, and the lid should be firm and sealed. The net weight of each barrel is 25kg, 40kg and 50kg. If the demander has special requirements, the supply and demand sides shall agree. "Moisture-proof" signs shall be marked on the packaging barrel. The surface of the packaging barrel shall be coated with a color mark that is not easy to fall off, and the color marks are as follows: F2n30 Black, F2n45 yellow, F2n90 Green, F2n125 blue. Should be stored in a cool, ventilated, dry, fire warehouse. Pay attention to moisture. It shall not be stored and mixed with inorganic acids and flammable materials. In the process of transport to moisture, fire, loading and unloading to light, to avoid impact and fall, so as to avoid damage to the package. Smoking, eating and drinking are prohibited at work. Contact, inhalation of zinc powder can be washed with soap water and water or saline. The patient visited hospital. She can drink enough warm water to induce vomiting when taking in. In case of fire, dry sand and dry powder can be used for fire suppression, and water and foam are prohibited for fire suppression.
