black wire screen

The large roll of galvanized wire is violently extinguished in oxygen and sparks radiate, while the sodium block and magnesium bar are extinguished in oxygen and no sparks radiate. This phenomenon is determined by the composition of large rolls of galvanized wire. The large rolls of galvanized wire used in the experiment are pig iron or steel wire, both of which are alloys of iron and carbon (complex substances containing the elements iron and carbon). When the carbon in galvanized wire is extinguished, carbon dioxide will be produced, and the solid will be changed into a gas, and the volume will shrink rapidly.

2. When the weather is too dry and humid, remember to blow dry the cage or move it to a place with heating to prevent dry crack damage.

One is to do a good job of galvanized wire packaging, avoid bumping, to ensure the integrity of the zinc layer;
