Temperature changing pigment packaging and drying device

Abstract

The invention provides a temperature changing pigment packaging and drying device which comprises a box body. The box body is divided into a cavity A and a cavity B through a metal partition plate. A sealing door is arranged at the opening of the cavity A. An air inlet and an exhaust port are formed in one side of the cavity A, wherein the exhaust port, a relay I and a vacuum pump are connected through an exhaust pipe, the air inlet, a relay II and an argon gas bottle are connected through an air inlet pipe, the metal partition plate is connected with a handle, and the metal partition plate is controlled by the handle to be closed; a heating device, an illuminating lamp and a temperature measuring device are arranged inside the cavity B, a gas-pressure meter is arranged outside the cavity B, the heating device and the temperature measuring device are connected with a console, a guiding rail is arranged at the bottom of the box body, and a load carrier can move along the guiding rail. According to the temperature changing pigment packaging and drying device, the color changing process of a temperature changing pigment can be effectively controlled, the saturability, the contract ratio and the brightness of colors are precisely controlled, waste products are prevented from being produced by the color display problem, production efficiency is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of packaging and printing equipment, in particular to a packaging and drying device for temperature-changing pigments. Background technique [0002] At present, temperature-changing pigments are a very important printing pigment system. It is an unstable system (it is difficult to change if it is stable), so its light resistance, heat resistance, and aging resistance are far inferior to ordinary pigments. The light resistance of temperature-changing pigments The color development process is easily affected by factors such as temperature and oxygen, which directly affects the correct display of the saturation, contrast and brightness of the printed pattern color. [0003] The discoloration temperature of temperature-changing pigments is not a temperature point, but a temperature range, that is, the temperature range from the beginning of discoloration to the end of discoloration. The width of this temperature range is...
