Iron Oxide black, also known as C.I. Pigment Black 11, Black or black red powder, which is the adduct of ferrous oxide and ferric oxide, in the form of tiny particles with a particle size of 0.1 μ M, the relative density is 5.18g/cm3, and the melting point is 1594 ℃. Insoluble in water and alcohol, soluble in concentrated acid and hot strong acid. It is magnetic and has high coloring power and covering power. It has good weather resistance, light resistance, atmospheric resistance, durability, water permeability and oil permeability. It is very stable in general organic solvents, with good alkali resistance and heat resistance up to 100 ℃. When heated at high temperature, it is easy to be oxidized and turn into red iron oxide. It is formed when burning at 200 ~ 300 ℃ γ- Type Fe2O3. It can cooperate with other subtle colors to form light Rao radiation, which is translucent.

Since the beginning of this year, China's auto industry has continued to grow rapidly. Especially, the growth of passenger cars has been particularly rapid. It has become the main driving force for the growth of China's auto industry, and it has promoted the optimization of the domestic auto structure. In the first quarter of this year, the proportion of cars in domestic cars reached 45%, an increase of 5 percentage points year-on-year. According to the statistics of the China Association of Automobile Manufacturers, in the first three months of this year, domestic production of cars totaled 1.29 million units and sales of 1.277 million units, an increase of 25.63% and 28.98% year-on-year. The output of cars was 579,900, and the sales volume was 567,000, an increase of 41.86% and 44.47%, respectively; the number of passenger cars was 326,500, and the sales volume was 332,700, an increase of 10.72% respectively. 9.48%. Due to tight railway transportation this year, road transport has grown substantially, stimulating demand for trucks. In the first quarter, the production and sales of trucks increased by 19% and 28.46%, respectively, and the production and sales volumes were 396,200 and 378,000, respectively. In the first quarter, domestic cars accounted for 45% of total production, passenger cars 25%, and trucks 30%. With the continuous and rapid growth of the production of automobiles, especially cars in China, the domestic automobile structure has been continuously optimized. However, there is still a big gap compared with the proportion of cars in foreign countries that account for 70% of the production of cars. Source: Xinhuanet
