Description
"Controlling the Speed of Iron Rusting" Changes in Matter PPT Courseware 2
scientific symposium
We have studied the reasons why iron rusts and conducted comparative experiments. Let us share the research results!
Experimental results:
Iron rust is related to air and water, and iron rust is the result of the combined action of water and air.
Cause Analysis:
The rust of iron requires the combined action of water and air. The speed of iron rusting varies in different environments. Iron rusts quickly in salt water, and the color of iron will change when it rusts.
After reading the above experimental record sheet, what conclusion can we draw?
Share your experimental results. Can we find the reason why iron rusts?
Anti-rust measures for iron products
Measures to prevent iron from rusting - destroy the conditions for iron to rust
Common methods to prevent iron products from rusting: (anti-rust)
1. Keep the surface of iron products dry and clean (isolate moisture)
2. Apply a layer of oil on the surface of the iron product; (to isolate moisture and air)
3. Paint the surface of iron products;
4. Plate a layer of wear-resistant and corrosion-resistant metal on the surface of iron products;
5. Made of stainless steel; (change the internal structure)
