A paint defoamer is an additive used to prevent bubbles from forming in paint or coatings during stirring, applying or spraying. It works by reducing the surface tension of the liquid, preventing bubbles from forming, and helping the foam to break and release quickly. This can make the paint surface smoother, prevent bubbles and pits in the coating, and improve the painting effect and quality...
Washing powder mainly includes detergent, decontaminant and foaming agent. Among them, the main task of the foaming agent is to produce rich foam, which can stir and dissolve the stains and suspend them in the water, thereby enhancing the washing effect. However, it should be clear that not the more foam there is, the better the washing effect will be. First of all, too much foam brings trouble to...
Polyether defoamers and silicone defoamers are the most effective in the fermentation industry. Polyether defoamers are widely used because of their good antifoaming ability and their suitability for thin fermentation broth. This type of defoamer mainly includes GP-type and GPE -type. GP- type defoamer is mainly formed by the polymerization of glycerol and propylene oxi...
With the continuous development of oil extraction technology, oilfield drilling has become an important part of the oil industry. However, during the drilling process, foam problems often cause troubles to drilling work, such as reducing drilling efficiency, increasing operational risks, and destroying wellbore stability. Therefore, how to effectively control foam has become an urgent problem to b...
The emulsions in many water-based defoamers are not very stable. To stabilize the emulsion, a small amount of thickener is added. When the defoamer solution is too dilute, using a defoamer thickener can save costs, so many manufacturers have used it. How should we choose a suitable thickener for the defoamer? It is recommended to choose according to the following characteristics. 1. A...
Polyurethane defoamer is a chemical substance widely used in industrial production. It plays an important role in the production process, helps to control the generation of foam, and improves the quality and performance of products. This article will explore polyurethane defoamers' characteristics, application areas and future development trends. Characteristics Polyurethane de...
Printed circuit boards (PCBs) require cleaning when they are manufactured for the following reasons: 1. Remove impurities: During the production process, impurities such as oil, flux residues, and dust particles may contaminate the circuit board, thereby affecting its performance and even causing circuit failures. 2. Remove solder slag: When assembling circuit boards, soldering operations are requ...
Among many industrial chemicals, defoamer is a common and important auxiliary agent. However, the answer to whether defoamers are dangerous products is not a simple "yes" or "no", but needs to be judged based on the specific ingredients and properties. First of all, most common defoamers are not dangerous products. They usually contain some relatively mild and chemically stable ingredients,...
