The manufacturer of Twin Screw Extruders for Powder Coatings tells you to add water or an appropriate liquid to the raw material powder and keep stirring. Extrude the stirred material from the perforated head or metal mesh with high extrusion pressure. Usually, after putting the material into a cylindrical container, the material is extruded with a screw.

The manufacturer of Twin Screw Extruders for Powder Coatings tells you that after using the frequency conversion technology, the pressure can be controlled, so that the appropriate linear speed can be selected. Single-screw extruder principle The single-screw is generally divided into three sections in terms of effective length, and the effective length of the three sections is determined according to the diameter of the screw, the pitch and the depth of the screw, and generally divided into one-third of each. The last thread of the feed port is called the conveying section: the manufacturer of Twin Screw Extruders for Powder Coatings tells you that the material here is not required to be plasticized, but it must be preheated and squeezed under pressure. In the past, the old extrusion theory believed that the material here is loose. , Later, it was proved that the material here is actually a solid plug, that is to say, the material here is a solid like a plug after being squeezed, so as long as the conveying task is completed, it is its function. The second section is called the compression section. At this time, the volume of the screw channel gradually decreases from large to small, and the temperature reaches the degree of plasticization of the material. The compression here is generated by the conveying section three, and it is compressed to one here. This is called the compression ratio of the screw (3 : 1), some machines also have changes, and the plasticized materials enter the third section. The manufacturer of Twin Screw Extruders for Powder Coatings tells you that the third section is the metering section, where the material maintains the plasticizing temperature, and it just delivers the melt material accurately and quantitatively like a metering pump to supply the machine head. At this time, the temperature cannot be lower than the plasticizing temperature. The temperature is generally slightly higher.
