Chemical Structure and Properties


Polyacrylamide is composed of repeating units of acrylamide, which can form linear or cross-linked structures depending on the conditions during polymerization. The chemical formula of polyacrylamide is (C3H5NO)n, where 'n' represents the number of recurring units. One of its most notable features is its ability to absorb large amounts of water, leading to the formation of a gel-like substance. This characteristic makes polyacrylamide highly effective in various applications, especially in hydrophilic environments.

Moreover, PQQ plays a significant role in promoting neuronal health. Studies suggest that PQQ supports neuroprotection, potentially reducing the risk of neurodegenerative diseases. It has been found to enhance the survival of neurons exposed to oxidative stress, lending credence to its possible therapeutic effects in neurodegenerative conditions such as Parkinson’s and Alzheimer’s diseases. The relationship between PQQ, mitochondrial function, and neuronal health underscores the importance of these organelles in the maintenance of cognitive functions and overall brain health.


Cooling towers are essential components in various industrial processes, power plants, and HVAC systems, where they play a critical role in dissipating heat and improving operational efficiency. However, like any system that manages large volumes of water, cooling towers are susceptible to problems such as scale buildup, corrosion, and biological growth. To mitigate these issues, effective chemical treatment is necessary. This article explores the significance of chemical treatment in cooling towers, the types of chemicals used, and best practices for maintenance.

Boiler feed water is the water that is supplied to the boiler for the generation of steam. The quality of this water is crucial, as impurities can lead to several operational issues, including corrosion, scale formation, and deposits on heat transfer surfaces. These problems can result in reduced efficiency, increased maintenance costs, and even catastrophic failures in extreme cases.

  • Common materials used in oil seals include nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material of the oil seal, the compatibility of the material with the working medium, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft at high speed must be considered. When the oil seal is working, the temperature of its lip is higher than the working medium temperature by 20~50°C. Attention should be paid when selecting the oil seal material. The working range of the oil seal is related to the material used for the oil seal: the material is nitrile rubber (-40~120°C), Aggreko rubber (ACM) -30~180°C, fluorine rubber (FPM) -25~300°C.

  • The CMR5H spark plug is designed to provide a high level of ignition efficiency, ensuring that your engine starts smoothly and runs at its best. This spark plug is suitable for a wide range of vehicles, including cars, motorcycles, ATVs, and more. Its durable construction and high-quality materials ensure that it can withstand the rigors of regular driving.
  • One of the main functions of the valve cover gasket assembly is to prevent oil leaks and keep the engine running smoothly. Oil leaks can be a significant issue as they can cause damage to the engine components and lead to decreased performance. The valve cover gasket assembly acts as a barrier between the oil in the engine and the outside environment, ensuring that the oil stays where it belongs.
  • Oil seals for cars

  • Most ERIKS oil seals, such as the types M, MST, R and RST, are made of NBR as standard.

  • Leather oil seals are commonly used for parts that are exposed to dirt and poor lubrication. The major advantage of this material is that it can function in cases where synthetic rubber cannot function. They are used for shafts that have rough surfaces that are more than what rubber seals can handle. This is because they are pre-lubricated and have the capacity to absorb liquids.

  • Disadvantages of fluoro silicone rubber:
  • In conclusion, silicone gasket sheets are a highly versatile material that offers excellent heat resistance, chemical resistance, electrical insulation, and flexibility. These properties make them an ideal choice for a wide range of sealing applications in various industries. Whether you need to seal gaps in machinery, prevent leaks in plumbing systems, or insulate electrical components, silicone gasket sheets are sure to provide a reliable and long-lasting solution.
  • Silicone gasket sheets are equally at home in the construction sector, where they serve as weatherstripping around windows and doors, preventing drafts and reducing energy loss
  • Wheel bearings also require oil seals to prevent the leakage of grease, which is necessary for reducing friction and ensuring the smooth rotation of the wheels
