Dimethicone for low temperature applications!
Now the country enters the low temperature mode, in the cold winter days, we often feel the cold wind, cold and unbearable low temperature. However, in this icy world, there is a kind of magical substance, which can play an extraordinary role in extremely low temperature, it is dimethicone oil.
Dimethicone is a lubricant and heat transfer medium with a wide range of low-temperature applications. Its low-temperature performance and thermal stability make it an indispensable presence in the cryogenic field. First, let’s take a look at the application of dimethicone oil in low temperature lubrication. In cold environments, mechanical equipment, instrumentation and electronic components often fail due to insufficient lubrication, and the emergence of dimethicone oil provides the perfect solution for them. It can provide excellent lubrication performance at very low temperatures to ensure the normal operation of equipment, so that the cold can not attack.
In addition to lubrication, dimethicone can also be used as a low-temperature sealant of choice. Thanks to its low viscosity and high chemical stability, it prevents gas and liquid leakage at low temperatures. Whether in extremely cold weather or in industrial equipment in low-temperature environments, dimethicone fluids provide a reliable seal and protect equipment from the elements.
In addition, dimethicone is an excellent low-temperature coolant. It has excellent thermal conductivity, and can effectively dissipate heat to maintain a stable working temperature of the equipment. Whether in electronic equipment, or in industrial production cooling system, dimethicone oil can play an excellent cooling effect, to ensure the normal operation of equipment.
In addition to the above applications, dimethicone oil can also be used as vacuum pump oil, solvent and heat transfer medium in petrochemical process, and preservative and antioxidant for frozen food. Its versatility and wide range of application areas make dimethicone oil an indispensable miracle in the cryogenic field.
Dimethicone, scientifically known as polydimethylsiloxane, is a silicone synthetic material with the appearance of a colorless, transparent, oily liquid that is commonly used as an active ingredient in a variety of creams, emulsions, solvent-based polishes, and aerosols in the form of automotive, furniture metal, and specialty polishing products. It is also used in some cosmetic ingredients, elastomers, plastic lubricants, electrical insulating fluids, defoamers and antifoam agents, mechanical fluids, release agents, surfactants, solvent-based surface treatments, and leather fat liquefiers.
Dimethicone defoamer in industrial foam applications
Dimethicone oil plays an important role in many fields due to its colorless transparency, wide viscosity range, coefficient of expansion and excellent shear resistance. Not only does it have applications in the electromechanical industry and healthcare, but it also plays a key role in products such as sewing thread smoothing agents, defoamers, mold release agents, lubricants and additives.
Dimethicone Antifoam Characteristics
Dimethicone defoamers are finely synthesized products made from fatty alcohols, amides, polyethers and hydrocarbons. Its advantage lies in its ability to quickly penetrate into the liquid and spread rapidly, effectively eliminating stubborn foam and fine foam. Even under strong alkaline or high-temperature environments, the defoaming effect can be maintained stably. Compared with silicone defoamer, dimethicone defoamer will not leave silicon spots on the surface of equipment or products after use, thus avoiding the impact on the appearance.
Dimethicone defoamer combines chemical stability, physiological inertness and excellent high and low temperature performance. Its good water solubility, can be quickly dispersed in the water environment; pH value between 6.5 and 7.8, to ensure the stability of defoaming in extreme conditions; low additive amount, the recommended dosage of 0.001-0.003%, easy to add directly; viscosity and density is appropriate, dimethicone oil viscosity of a wide range (0.65-1,000,000mm ² / s), according to the specific needs of the product can be adjusted. The viscosity and density are suitable.
