1. Applications in the electromechanical industry

Methyl silicone oil is widely used in electric motors, electrical appliances, electronic instruments as an insulation medium for temperature resistance, arc corona resistance, corrosion resistance, moisture-proof, dust-proof, and now also used as an impregnating agent for transformers, capacitors, scanning transformers for TV sets, etc. In various precision machinery, instruments, and meters, it is used as liquid anti-vibration and damping materials. The shock absorption of 201 methyl silicone oil by the temperature is small, mostly used with strong mechanical vibration and ambient temperature changes in the occasion, used in aircraft, automotive instruments. For example, the Dow transformer silicone oil distributed by Qingdao Hongruize Chemical has been used in the instrumentation of large power plants and has made a certain contribution to the west-east transmission of electricity.

 

2. Smoothing agent for sewing thread

Methyl silicone oil is used in large quantities as an oiling agent for raw fiber and raw cotton, an oiling agent for spinning, and a soothing agent for sewing thread. The oil agent for raw silk and raw cotton is low viscosity methyl silicone oil, generally 10 viscosity, for example, Hongruize distributes a large number of Dow 10 viscosity silicone oil used in the production process of spinning spandex. The smoothing agent for the sewing thread is medium to high viscosity methyl silicone oil, generally using 500 viscosity silicone oil. Using the thermal stability of methyl silicone oil and low viscosity-temperature coefficient, with an antistatic agent, emulsifier, and other oils made of spinning oil, used in the nylon, polycool spinning process, to prevent the spinning process of very fine monofilament bundle from the nozzle when the spinneret spray and fast winding when the breakage and loosening caused by electric. When melting the spinning, the nozzle should also be treated with dimethyl silicone oil for mold release to prevent carbide or molten material from adhering and causing spinning breakage.

 

3. As a defoamer

Because of the small surface tension of dimethyl silicone oil, and insoluble in water, good chemical stability, non-toxic, as defoamer has been widely used in petroleum, chemical, medical, pharmaceutical, food processing, textile, printing and dyeing, paper, and other industries. The secondary processing of silicone oil can also produce defoamer emulsions for aqueous systems, such as the Dow defoamer AFE-1410/0050 distributed by Qingdao Hongruize has a large number of applications in the industry.

 

4. As a mold release agent

It is non-stick with rubber, plastic, metal, etc., and can also be used as a mold release agent for molding and processing of various rubber and plastic products, and in precision casting. It is not only easy to release the mold with it, but also makes the surface of the products clean, smooth and clear texture.

 

5. As insulation, dustproof, anti-mildew coating

After dipping and coating a layer of 201 methyl silicone oil on the surface of glass and ceramic ware and heat treatment at 250-300℃, it can form a semi-permanent film with waterproof, mildew-proof and insulating properties. Insulated devices treated with dimethyl silicone oil to improve the insulating properties of the devices. Optical instruments treated with dimethyl silicone oil can prevent lenses and prisms from becoming moldy. The vials treated with dimethyl silicone oil, which prolongs the shelf life of the drug and does not cause the preparation to be lost due to sticky walls. It can be used to lubricate the surface of the film, reduce friction and prolong the life of the film.

 

6. As lubricant

Dimethyl silicone oil can be used as a lubricant for rubber, plastic bearings and gears. It can also be used as a lubricant for rolling friction of steel to steel at high temperature, or when steel rubs against other metals.

 

7. As an additive

Dimethyl silicone oil can be used as an additive for many materials, for example, it can be used as a brightening agent for paints, adding a small amount of silicone oil to paints can make the paint not float pack, not wrinkle, and improve the brightness of the paint membrane. Adding a small amount of silicone oil to the ink can improve the printing quality; adding a small amount of silicone oil to the polishing oil (such as car varnish) can increase the brightness, protect the paint film, and have excellent waterproof effect.

 

8. Other aspects

With its high flash point, odorless, colorless, transparent and non-toxic to human body, it is used as a heat carrier in oil baths or thermostats in steel, glass, ceramics and other industries and scientific research. With its good anti-shear property, it can be used as hydraulic oil, especially aviation hydraulic oil. Treating rayon spinning head with it can eliminate static electricity and improve drawing quality. Adding silicone oil to cosmetics can improve the moisturizing and protective effect on the skin, etc.

 

As industrial monosodium glutamate in the use of the process is often very critical, the choice of good quality supply of stable silicone oil products to save effort to save half the effort!
