Abstract

The invention relates to a low-temperature solidified powder production line system and a production process thereof. The production line system comprises a mixer, an extruder, a roller type tablet press, a cyclone separator and a stirring tank which are sequentially arranged according to a production process route. The production process comprises the following steps: S1, low-temperature mixing;S2, low-temperature extrusion; S3, tabletting at low temperature; S4, separation; S5, stirring; and S6, low-temperature grinding. Transformation is carried out on the basis of existing powder coatingproduction line equipment, so that the material temperature in each process node is controllable and adjustable, and the powder coating production line equipment can be suitable for the production characteristic of low-temperature solidified powder. In the technological process, different temperature parameters are set for mixing, extrusion and tabletting respectively, so that the materials alwayskeep good properties on the technological route, and finally, the materials meet the grinding requirements through the quenching process of heating and cooling in sequence in the stirring tank.

Description

technical field [0001] The invention relates to the technical field of powder coating production, in particular to a low-temperature curing powder production line system and a production process thereof. Background technique [0002] Powder coating is widely used in modern industrial production due to its advantages of economy, environmental protection, high efficiency and excellent performance, but some of its weaknesses are also obvious. If the curing conditions are relatively harsh, the curing temperature is generally between 180 and 200 °C. If the curing temperature can be reduced, energy consumption can be reduced, which is the need for environmental protection, energy saving and emission reduction. [0003] The high curing temperature not only leads to high energy consumption, but also restricts the coating of some substrates that cannot withstand high temperatures, such as plastics and wood, which greatly affects the expansion of the application field of powder coa...
