In the textile printing and dyeing process, various textile auxiliaries are added during production and production to ensure the quality and performance of textile products. Therefore, the treatment of textile wastewater can easily cause a large amount of foam, and the foam is relatively stable and difficult to eliminate. Aiming at the foam problem in textile water treatment, Nanhui defoamer manufacturer specially developed and designed a wastewater treatment defoamer for a textile printing and dyeing factory. The defoaming effect is very good. The following editor briefly introduces the foam problem encountered by the company and the solution.

Customer problem
In mid-May 2021, Mr. Yang, the person in charge of a textile company in Bangkok, Thailand, found the manager of Nanhui Yoyo on the Internet. He said that he encountered the foam problem of textile wastewater treatment. He also tried defoamer, but there was still foam, which could not be solved. I have a headache now. I learned by phone that Mr. Yang’s textile factory used a large number of chemical auxiliaries in the manufacturing process, including a large number of surfactants, and encountered foaming problems during the entire process of textile pretreatment, dyeing, and printing, which affected The progress of the textile process, and the foam also led to affect the quality of printed products. The most important thing is in the process of textile wastewater treatment, textile auxiliaries also cause a lot of foam problems.

Customer requirements
Therefore, Mr. Yang hopes that Nanhui defoamer manufacturers can provide a defoamer with fast defoaming speed and longer foam suppression time, which can specifically solve the foam in the textile production and the foam in the sewage treatment process. Mr. Yang has the following requirements for defoamers:
1. The dosage of additives should be relatively small, with better cost performance.
2. The defoaming speed of the defoaming agent should be relatively fast, and the defoaming performance is strong;
3. The anti-foaming agent has a long foam suppression time, which can inhibit foam generation for a long time;
4. Good stability, will not chemically react with other chemical additives, and will not affect the function of other additives.
Solution
Nanhui defoamer technology According to the customer Mr. Xu’s quality requirements for defoamers, he recommended a silicone defoamer for Mr. Xu, and sent three samples to Mr. Xu, Nanhui’s silicone defoamer The agent is composed of polyether and dimethyl silicone oil, with good comprehensive defoaming performance. Because of its lower surface tension than the system, it has good affinity with the foam, can diffuse on the foam film and enter the foam, and quickly eliminate and kill Foam.

After trial, the customer Mr. Xu affirmed the defoaming performance of one of the silicone defoamers. When added to textile production, it can produce a good foam control effect. Secondly, the defoaming and dispersing quickly in sewage treatment, after adding, you can see that the foam is quickly eliminated and the defoaming time is fast, and the addition of this defoaming agent is relatively simple to use, which can meet the needs of defoaming.
Mr. Xu gave feedback that Nanhui’s silicone defoamer has high defoaming ingredients, high concentration, and a relatively small additive dosage. In early June, Mr. ordered 3000 kg of silicone defoamer at Nanhui. After use, the foam problem in textile production and the problem of water treatment foam have been solved.
Nanhui is a manufacturer with years of application experience. It has far more defoaming technology than other antifoaming agents in the market. From the above cases, we prove the strength of our Nanhui defoamer. We have a group of excellent defoaming engineers, and an independent laboratory that facilitates defoaming experiments with foams that are difficult for customers to solve.
