Printing glue defoaming solution

Customer question

In recent years, water-based printing has become more popular in the world, and water-based printing products have become more and more popular among fashion masters. At the same time, printing manufacturers also mean that the production of water-based printing products requires higher technology. Printed products have high requirements for their air permeability and color fastness. The printing process is more complicated. The printing glue is prone to foaming due to the substitution of air during the production process. The existence of foam affects the quality of the product on the one hand, and also affects the normal production process. In view of the foaming problem of printing glue, printing manufacturers can add printing glue defoamer for treatment. The following is the printing glue defoaming solution provided by Nanhui for customers.

1. Customer information: Zhengzhou Ruitai Printing is a manufacturer of textile printing products, and encountered the problem of foaming of printing glue in the production process. Find Nanhui through the Internet, hoping to find a suitable defoaming solution for printing glue.

2. Sample information: printing glue

Customer request

1. Adding printing glue in the production process can quickly eliminate foam;

2. The defoaming effect is good and can not affect the quality of printed products.

Solution

1. Causes of foaming of printing glue

(1) The glue production is not compatible with some raw materials.

(2) Air enters the slurry during the mixing process in the glue production process. This kind of glue has poor leveling and swelling appearance.

(3) Too much water is added to the glue production, and the scraper, water and the slurry molecules generate electric charges during printing. There are always small irregular bubbles when the apparent screen is started. This phenomenon is normal glue printing This phenomenon can also occur when diluted with water.

2. The hazards of foaming in printing glue

If there is foam in the dyeing slurry, if the defoaming treatment is not carried out in time, stains, white spots, uneven color, etc. will be easily formed on the textile products, which will cause the uneven color of the textile products and the blurry pattern, which will seriously affect the product Quality hinders production progress.

3. Recommend printing glue defoamer

The printing glue defoamer developed by Nanhui is made of ether, fatty alcohol and a variety of active additives through a special process. Easy to disperse in water-based system, strong self-emulsification, good defoaming, long foam suppression time, especially for water-soluble polymers and medium and low viscosity systems. It has the advantages of good defoaming, good foam suppression, good leveling, low dosage, no floating oil, no fish eye holes, and does not affect the appearance of the product and the coating performance.

4. Application fields of printing glue defoamer

Nanhui printing glue defoamer is widely used in textile pretreatment agent series products, general OK oil penetrant (paste dye type), antique oil, printing, acrylic sizing agent, textile chemical fiber oil, refining agent, fabric Dyeing and finishing, medium and normal temperature polyester dyeing, textile sizing and spinning, weaving auxiliaries, desizing, bleaching, washing, water treatment systems, defoamers for the whole process of textile dyeing, defoaming and defoaming in industrial chemical systems with high temperature and strong alkali deal with.

5. Anti-foaming experimental plan for foaming of printing glue

Nanhui metalworking fluid defoamer is added in the production, which can control the foam from the production source, optimize the formula of the metalworking fluid, reduce the surface tension of the system, and reduce the foaming power. The defoaming agent can also be added during the use of metalworking fluids, generally about three thousandths of the foaming system. The addition amount is small, which can quickly defoam the foam and inhibit foam regeneration for a long time.

The source manufacturer of Nanhui defoamer can solve various industrial foam problems in a targeted manner. If you encounter bubble problems in related industries, you can call Nanhui technical specialist Yoyo +86 134 28601010
