In the chemical experiment, how does the wire mesh use? What are the effects?
when below the sieve The reaction can be stopped to achieve the purpose of controlling the reaction.
manufacturing device, the solid reactant on the sieve plate, the liquid from bottom to top injection, when the liquid level is higher than the sieve can begin to reflect,
So that the catalytic reaction of iron as a catalyst is more pronounced for the blocking effect. In the solid-liquid reaction in a kind of controllable gas
Increase the contact area. So that the reaction of iron to participate more intense (fast)
