Viscosity precise control device

Abstract

Viscosity precision control device, involving precise solvent control technology, including raw material tank, solvent delivery pump, several flowmeters and ink basins, the flowmeters in front of each ink basin are connected to a high-level storage tank by the same connecting pipe, and the solvent delivery pump The output pipe is connected to the top of the high-level storage tank. Through this device, the ink viscosity of the ink basin can be controlled within ±0.2 seconds (Zai En 4#), and the color difference ΔE≤0.5.

Description

technical field [0001] The invention relates to a solvent precise control technology, which is mainly used in the manufacturing field that requires precise solvent addition process, such as the printing industry. Background technique [0002] In the printing process, the control of ink viscosity is very important. Appropriate and stable viscosity is directly related to quality issues such as color uniformity, color difference, gloss, pigment adhesion, and static electricity, which affect printed products. yield and work efficiency. Appropriate ink viscosity value can be obtained through repeated experiments, but the continuous and stable control of ink viscosity value is indeed a prominent problem faced by the printing industry at present, and has become the primary obstacle to high-quality printing. In order to solve this problem, at present, the ink viscosity is controlled by using a diaphragm pump to transport the solvent, and the ink viscosity is adjusted by controlling...

Problems solved by technology

However, the disadvantage of the viscosity controller is that the uneven stirring of the solvent will affect the effect of the sensor. In addition, the components involved in the controller need to be cleaned in time, and are easy to be damaged, so it cannot ensure the stable response of the ink viscosity for a long time.

This is a huge misunderstanding
