This knowledge of Rotary tiller products should be understood
Rotary tiller products are made of yellow powder or granules. Relative density 9.53; melting point 885 ℃; boiling point 1 470 ℃. When heated to above 300 ℃, it becomes lead tetroxide, and it becomes a Rotary tiller products when the temperature continues to rise. Insoluble in water and ethanol, soluble in nitric acid, lye, ammonium chloride; can harden with glycerin. Under heating, a Rotary tiller product is easily reduced to metallic lead by hydrogen, carbon, carbon monoxide, etc.
Rotary tiller products are mainly used for electron tubes, picture tubes, optical glass and X-ray-proof lead glass and radiation-proof rubber products. Grid lead electrodes for filling lead storage batteries.
Rotary tiller products are drugs that can cause hypochromic anemia, severe abdominal pain, lead poisoning mania, lead poisoning paralysis polyneuritis, etc. Olmg/m3 is the maximum allowable concentration in the air.
