Advantages of surfactants in defoamers 1. First of all, it has temperature resistance and hydrolysis resistance. The hydrophilic group in the silicone surfactant cannot be directly connected to the silicon atom of the siloxane chain. The hydrophilic group directly connected to the silicon is easily hydrolyzed to form a silanol group, which can further condense…
What should I pay attention to when using silicone defoamer Generally speaking, foam does not cause any major harm in real life, and it can also play a certain aesthetic role. However, if foam appears in industrial production, it is different, and it can easily cause certain harm. In this case, a certain amount of…
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…
The higher the antifoaming performance of the defoamer, the better the foam breaking As a defoamer, there are two methods of using it: adding it when foaming occurs and adding it in advance to prevent foaming. The amount of addition ranges from a few ppm to 1%, and can be increased or decreased according to…
Composition and selection of defoamers Defoamers, also known as antifoaming agents, will produce a lot of harmful foams in the process of industrial production, and defoamers need to be added. They are widely used to remove harmful foams generated in the production process of latex, textile sizing, food fermentation, biomedicine, coatings, petrochemicals, papermaking, industrial cleaning…
The difference and mechanism between defoamer and deaerator In daily life, foam is very common. Although some common foams will not cause much harm, they will affect industrial production. In such cases, defoamers or deaerators need to be added for treatment. So, why can’t some defoamers be replaced by deaerators? What is the difference between…
Industry analysis of water-based defoamers At present, as far as the current water-based defoamers are concerned, the performance of polyether and silicone defoamers is the best, and the modification and development of new varieties of these two types of defoamers are also relatively active. Water-based defoamers are widely used for defoaming in the production processes…
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…
