Introduction to the use of textile color paste defoamer
In the textile industry, the use of color paste plays an important role in the printing and dyeing process. However, color paste often produces a large amount of foam, which brings a lot of trouble to production.
The working principle of textile color paste defoamer is mainly to destroy the stability of foam through the action of surfactants. They can reduce the surface tension of liquid and form a thin and uniform wetting layer in the foam film, thereby making the bubbles Breaks and dissipates quickly.
The following will introduce the use of textile color paste defoaming agents to help you apply them correctly and efficiently in the printing and dyeing process:
1. Control the amount of addition: The amount of addition should be controlled according to specific process requirements and foam conditions. In general, the initial addition amount can be set based on experience and adjusted through experiments to achieve appropriate results. It is recommended to conduct a small sample test first to determine the appropriate addition amount before proceeding with mass production.
2. Stir and mix evenly: Before use, it needs to be fully stirred evenly. You can use a stirrer or mixing equipment to fully mix the defoaming agent with the color paste to ensure that it is evenly distributed throughout the color paste. The mixing time and speed should be based on Specific product and process requirements are adjusted.
3. Timely addition: The addition time should be as close as possible to the stage where foam is generated during the printing and dyeing process. Under normal circumstances, you can choose to add defoaming agent in links such as coating, printing or dyeing that involve more foam generation. If one addition is not enough to control the foam, you can add it in batches and pay attention to adjusting the amount and time interval.
4. Pay attention to adjusting the pH value: The effect of the defoaming agent may be affected by the pH value of the color paste. It is recommended to adjust the pH value of the color paste to a suitable range while using it. By adjusting the pH value, the effect of the defoaming agent can be further improved and the generation of foam can be reduced.
