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...
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...
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...
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...
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...
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...
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...
In the leather production process, the main function of the defoamer is to control and reduce the generation of foam. During the processing, the generation of foam will cause some problems, such as affecting production efficiency, quality and working environment. Therefore, adding a suitable defoamer is a necessary condition to solve these problems. The use of defoamers in leather production can i...
As oil is a non-renewable resource, workers are very careful when extracting crude oil and do not dare to cause any waste. The team that carries out crude oil exploration and extraction operations in the oil field is called the drilling engineering team. After the team members turn on the drilling equipment, under the action of pressure, the crude oil hundreds of meters deep underground will be ex...
Defoaming agent for paper making is a chemical additive used to control foam during paper production. It can effectively reduce the generation and stability of foam, thereby improving production efficiency and product quality. This article will introduce in detail how to correctly use defoaming agents for papermaking, and explain their functions and precautions. 1. Choose a suitable defoaming agen...
