Description

Technical Field

[0001] This utility model relates to the field of ink additive formulation technology, specifically to an ink additive formulation device with waste gas treatment function. Background Technology

[0002] Ink additives are auxiliary materials added during the production and use of inks to improve their performance. They do not directly participate in the color development or coating process of inks, but enhance the overall performance of inks by adjusting their rheological properties, adhesion, drying speed, gloss, and antistatic properties. They can optimize printing quality, improve production efficiency, and reduce problems in the production process, thereby meeting the needs of different printing processes and products.

[0003] During the formulation of ink additives, some waste gases are generated due to solvent evaporation and byproducts of chemical reactions. These waste gases not only endanger the health of operators, potentially causing acute symptoms such as dizziness, nausea, and difficulty breathing, but long-term exposure may also increase the risk of chronic diseases such as cancer. Furthermore, if the waste gases are not properly treated, they can pollute the surrounding environment, affect air quality, and even cause safety hazards such as fires or explosions. Further development and improvement are needed. Utility Model Content

Then, it passes through the top of the partition plate and enters the purification box on the other side of the partition plate, which is filled with activated carbon filter plates. The waste gas undergoes secondary purification treatment through the activated carbon filter plates. Finally, the gas obtained after double purification is discharged through the exhaust pipe, while the prepared ink additives are discharged through the discharge pipe and discharge valve.
