After the mixture is milled into a certain size of powder, the molding method is used to suppress the formation. The graphite anode plate has certain shape, size and physical mechanical properties.
A single form of small graphite anode plate generally used mechanical press (eccentric press or punching machine), and the manufacture of large pieces of blank, the use of hydraulic press. The pressure of the unit is 100~ 250MPa, and the pressing temperature is generally controlled above 15T to prevent the cracking of raw products. The product volume density is the control item because it: affects the performance of the final products.
The use of artificial resin to make graphite anode plate, the general use of hot pressing method, that is, the use of electric mold, temperature around 200T (depending on the nature of binder). First, put the powder into the heating mold, then pressure, to maintain 3-5 minutes, unloading and remove the product. Using this method to suppress the efficiency is low, but the product does not need sintering, reduces the process, the comprehensive economic benefit is better.
In order to improve the efficiency of the compaction, and make the polymerization resin heat evenly, sometimes suppressed and then in the thermostat box treatment once, the effect is better.
Single Molding suppression
With the rapid development of household appliances and automobile industry, the requirement of small-scale nonferrous graphite anode plate is increasing, and it is imperative to reduce the cost and single molding in order to improve production efficiency.
A single molding is widely used mechanical presses, eccentric presses per minute can be suppressed products 8 ~ 15 pieces. And the use of the transformation of ordinary punch, each minute can be suppressed products around 40, high production efficiency.
