1, prepared A4 paper, marker, Gou Xianbi.
2. First, determine the approximate position of the figure to be drawn on A4 paper. Draw the frame of handwritten newspaper on A4 paper with Gou Xianbi.
3. Draw some water heaters, foam, letters and bow lace decorations around the frame. Then, write the headline "Prevention of carbon monoxide poisoning" at the top of the handwritten newspaper.
4. Frame the handwritten newspaper with beautiful colors. Then, paint all the decorations around the frame with beautiful colors.
Finally, draw a grid with horizontal lines in the box, so that the handwritten newspaper can be drawn.
Use of carbon monoxide
1. Making gas fuel: carbon monoxide can be used as gas fuel, such as water and gas, and the mixture of carbon monoxide and hydrogen can be converted into methane through air respirator for power generation.
2. Smelting metallic copper: Carbon monoxide can also be used to smelt metallic copper, and high-purity metallic copper can be obtained by reacting with copper oxide.
3. Industrial production: Carbon monoxide is used in industrial production to make chemicals, such as formaldehyde and acrylic acid. At the same time, it is also used in industrial processes, such as steelmaking and synthesis gas production.
4. Medical use: Carbon monoxide can be used to measure the concentration of hemoglobin in medical treatment, which is helpful for doctors to diagnose and treat anemia and other related diseases. At the same time, carbon monoxide can also be used for medical treatment. For example, in hyperbaric oxygen therapy, carbon monoxide can increase the oxygen content in the blood and improve the therapeutic effect.
