Description

Technical Field

[0001] The utility model relates to the technical field of storage and maintenance of thermosetting powder coatings, in particular to an anti-oxidation device for thermosetting powder coatings. Background Art

[0002] Thermosetting powder coating is a new type of powder material with resin powder as the main raw material. It can harden on the surface of an object after heating, providing effective physical protection for the surface of the object. It is a new type of material widely used in furniture production, decoration and industrial sheet material production industries.

[0003] Thermosetting powder coatings may change color during storage. The main reason is that the oxygen in the air undergoes an oxidation reaction with the active powder material in the material, resulting in color change. However, most existing storage methods for this material lack anti-oxidation design. The powder is very easy to oxidize during storage, resulting in a short storage time and a decrease in quality after storage.

[0004] In order to solve the above problems, we have made improvements and proposed an anti-oxidation device for thermosetting powder coatings. Utility Model Content

An inflation pipe is fixedly installed on the left end of the top surface of the inner wall of the gas transmission bin, and the inflation pipe is fixedly connected to the gas outlet of the nitrogen cylinder through a gas transmission hose.

[0010] As a preferred technical solution of the present invention, the oxygen concentration sensor and the nitrogen concentration sensor are both fixedly connected to the center of the top back of the inner wall of the storage bin by screws, and are both electrically connected to the control panel through lines. An air outlet is provided at the top right side of the inner wall of the storage bin, and the proximity switch is located below and close to the air outlet, with the probe of the proximity switch facing downward, and the proximity switch is electrically connected to the control panel through lines.
