The general mixing temperature is 80~90C, this temperature range is very easy to evaporate the water in the material. But there must be a certain amount of evaporation time.
If the raw material of the ton bag is brand new, adding masterbatch, sometimes adding color masterbatch, is more dry, there is no need to carry out mixing and heating. Just mix for a while.
Under normal circumstances, the pellets and masterbatch are not moisture-proof and moisture-proof. Only the masterbatch is likely to be cold or very easy to absorb moisture from the original factory. Under such conditions, it is recommended to mix the masterbatch first, not necessarily hot. The particles rub against each other and become hot and dry. Then add the pellets and masterbatch and mix them evenly.
If a small amount of recycled particles is added, the masterbatch and recycled particles can be mixed and heated first to remove water, and then the particles and color masterbatch can be mixed and evenly balanced.
The mixing material relies on the friction in the middle of the material to evaporate the moisture, and there is no need to carry out additional heating and consume energy. The consulting companies use high-speed mixers similar to those shown in Figure 2-3. In fact, this type of mixer is uncomfortable for mixing plastic woven materials.
It is especially suitable for heating and mixing raw materials and slurries, etc. to use this type of mixer. One is feeding 5-feeding port: 6 motor shaft: 7-motor: 8 feeding port height-to-width ratio. Efforts. Second, Shanghai has to look out for materials in a fully open manner, and fear that the saliva will not evaporate. Third, it consumes too much energy. Fourth, the price of machinery and equipment is very expensive.
