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...
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...
When using defoamers in wastewater treatment, the following methods can make the effect better: 1. Determine the appropriate amount of addition Small-scale test to determine the initial dosage: First, conduct a small-scale test, which can generally be carried out in a laboratory or a small treatment facility. Add defoamers to the wastewater in different proportions to observe the def...
Fountains are an art form that combines water and light and are commonly found in parks, squares, hotels and commercial areas. Fountains come in a variety of shapes, colors and music, providing visual and auditory enjoyment. Today's designs strike a balance between beauty and functionality; they are often illuminated at night, adding to the attraction of the attraction. However, fountains may prod...
In many industrial production and processing processes, the appearance of foam is often a headache. Whether in the chemical, food, pharmaceutical, or coating, sewage treatment and other industries, foam may bring a series of problems, such as reducing production efficiency, affecting product quality and even increasing production costs. The correct use of defoamers is particularly important. So, h...
Flue gas desulfurization refers to the process of removing harmful gases such as sulfur dioxide (SO₂) from flue gas by physical or chemical methods. Sulfur dioxide is one of the main pollutants produced when burning fossil fuels containing sulfur. It is highly corrosive and environmentally harmful, so it is very important to effectively control it. Main methods of flue gas desulfurization 1...
