The influence of defoaming agent on my country’s papermaking engineering Foam in pulp is a headache. It hinders the implementation of process conditions and the normal operation of equipment, and may become a serious problem in pulping, papermaking and waste liquid treatment. So what is the help of defoaming agents in the papermaking industry? Let’s…
What is an emulsion defoamer? The main components of emulsion defoamers are fatty alcohols and their derivatives. The structure of the main material fatty alcohol is an amphiphilic structure similar to that of surfactant molecules. One end of it is a lipophilic long-chain carbon-hydrogen bond, and the other end is a hydrophilic hydroxyl group. Since…
Requirements for use of water-based defoamers In the current industrial production field, water-based defoamers are the most outstanding products in industrial production. They can effectively play a defoaming role during the application process. However, with the continuous development of industry, more and more types of water-based defoamer products are used. However, different water-based defoamer products…
How to choose thickener in defoamer In actual applications, in most water-based defoamers in the industry, a small amount of thickener will be added to stabilize the emulsion. So what kind of thickener should be selected in the defoamer? 1. You should choose a thickener with good stability. Some thickeners have good thickening effect at…
Detailed overview of crude oil defoamers Although defoamers are very common raw materials in the modern decoration industry, especially in the selection of wall decoration coatings, different types of defoamers are usually selected, such as water-based defoamers. In fact, defoamers are used not only in the decoration industry, but also in crude oil energy products.…
Explain the application of defoamers in the paper industry In the papermaking industry, defoamers are mainly used in the following three aspects: 1. Use of defoamers in the pulp manufacturing process. In China, general paper mills no longer use defoamers. However, in the production of sulfite bleached wood and reed pulp, high temperature and strong…
How can plastic defoamers be added and used? Driven by the huge demand for raw materials and products in various industries in China, major upstream manufacturers are also carrying out production in full swing. And in order to ensure their strong competitive position in the industry, product quality can basically be guaranteed. It can be…
Hydrophobicity and fermentation process of polyether defoamer Polyether modified silicone defoamer is easily emulsified in water, also known as “self-emulsifying defoamer“. When the temperature is above its cloud point, it loses its solubility and mechanical stability in water, and is resistant to acids, alkalis and inorganic salts. It can be used for defoaming under harsh…
