The nature and use
of polyether defoamer in the field of raw materials for chemical production
1. Introduction

In the production process of chemical products, the generation of foam is a common problem. These bubbles not only affect the efficiency of production, but may also have a negative impact on the quality of the product. In order to solve this problem, defoaming agents are widely used. Among them, polyether defoamer has been widely used in the field of chemical production raw materials because of its excellent performance.

2. the properties of polyether defoamer

polyether defoamer is a non-ionic surfactant with good defoaming and anti-foaming properties. Its molecular structure contains a large number of ether bonds and hydroxyl groups, these groups make polyether defoamer hydrophilic and lipophilic, can effectively reduce the surface tension of the liquid, destroy the stability of the foam, so as to achieve the effect of defoaming.

In addition, the polyether defoamer also has the following properties:

1. Good thermal stability: it can be used at high temperatures and is not easy to decompose.
2, low toxicity: the impact on the human body and the environment is small.
3. Good compatibility: It can be mixed with a variety of chemicals without affecting the performance of the product.

III. Use of polyether defoaming agent

polyether defoaming agent has a wide range of uses in the field of chemical production raw materials, mainly used in the following aspects:

1. Petrochemical industry: in the process of petroleum processing, such as the production of lubricating oil and fuel oil, the production of foam will affect the quality and processing efficiency of products. The use of polyether defoamer can effectively eliminate foam and improve product quality and processing efficiency.
2. Polymer production: In the polymer production process, such as the production of polyethylene and polypropylene, the production of foam will affect the performance and appearance of the product. The use of polyether defoamer can eliminate foam and improve product quality.
3. Paint and ink production: In the paint and ink production process, the production of foam will affect the leveling and appearance of the product. The use of polyether defoamer can eliminate foam and improve product quality and brushing effect.
4. daily chemical products: in the production process of shampoo, shower gel and other daily chemical products, the production of foam will affect the use experience and sensory effect of the product. The use of polyether defoamer can control the generation of foam and improve the experience of the product.

4. Conclusion

In general, polyether defoamer has been widely used in the field of chemical production raw materials because of its excellent performance. It can effectively eliminate foam, improve product quality and processing efficiency, and play an important role in ensuring the smooth progress of the chemical production process.
