Problems solved by technology

[0007] 1. Natural standing, centrifugal mechanical gas-liquid separation and other methods, the production process takes a long time, and it is difficult to achieve continuous production;
[0008] 2. For methods such as decompression, centrifugal mechanical gas-liquid separation, and bubble trapping, some mechanical equipment needs to be purchased, which increases the investment in equipment and also increases the probability of generating new bubbles;
[0009] None of the above techniques can effectively remove the microbubbles in the fluid

Embodiment Construction

[0023] As shown in Figure 1, fluid preparation is an important part of the entire coating process, so the fluid preparation system is also very important. It includes various unit operations before coating, such as dissolving, stirring, conveying, filtering, degassing, mixing, temperature control, etc. These operations have a great impact on the quality of the final coated product. Firstly, the fluid is dissolved and stirred in the coating pot 1, and then sent to the filter device 3 by the power unit 2 for filtration, and then sent to the ultrasonic degasser 4 for degassing. After coming out of the ultrasonic degassing device 4, the fluid passes through the temperature control device 5 to adjust the temperature of the fluid, and then goes to the mixing device for mixing, and then passes through the online bubble detection instrument 8 for bubble detection, and finally can be sent to the applicator for coating .

Abstract

The invention discloses a degassing method of coating flow, which comprises the following steps: adopting ultrasonic wave with frequency at 25-39Hz as vibrating source, utilizing cavity action of ultrasonic wave shock to increase diameter of micro-bubble in the flow as well as lifting speed continuously until liquid surface, exhausting from vent, eliminating micro-bubble in the flow. The ultrasonic degassing device consists of flow degassing tank and at least one ultrasonic vibrator, wherein the degassing cavity is set in the flow degassing tank, the ultrasonic vibrator is set on the bottom of degassing tank, which lies under the degassing cavity.

Description

technical field [0001] The invention relates to a degassing method and device for coating fluid. Background technique [0002] Fluid thin film coating technology is widely used in the production of many products, including various grades of processed paper, functional paper, newsprint, packaging materials, photosensitive drums of copiers, audio and video tapes, floppy disks and optical drives of computers, microelectronics industry Coating is one of the most critical technologies for printed circuit boards, textiles, various functional films, battery pole pieces, and silver salt and non-silver salt photosensitive materials, etc. [0003] Fluid preparation is an important part of the overall coating process. It includes various unit operations before coating, such as dissolving, stirring, conveying, filtering, degassing, mixing, temperature control, etc. These operations have a great impact on the quality of the final coated product. [0004] All coating fluids dissolve som...
