Silicon oil, as a multifunctional lubricant, is widely used in demarcation, anti -sticking and smooth treatment. In industries such as rubber, plastic, metal casting, glass, paper, and fiber production, the use of silicon oil has a long history, and with the development of technology, its application scope and dosage continued to expand.

Classification and characteristics of silicon oil

High -viscosity silicon oil: Provide excellent modeling and anti -viscosity performance, while maintaining smooth surface treatment.

Low viscosity silicon oil: It has excellent coating and surface affinity, suitable for fine coating applications.

Typical application of silicon oil

Die meta -based silicon oil: A commonly used silicon oil, its viscosity range is usually between 0.1 and 30Pa · s, which can balance the release and coating performance.

Methayzhenyl silicon oil: In some particular applications, such as fiber production, it is favored by its heat stability and low -stick temperature coefficient.

Formula and use of silicon oil

Silicon oil can not only be used alone, but also can meet different industrial needs by formulating solutions, lotion, qi mist or fat ointment.

Silicon oil is used as a deserter/anti -adhesive

Silicon oil is widely used and important in anti -adhesives. Its unique physical and chemical properties make it a leader in the field of anti -adhesion. As the main role of anti -adhesives and its application in various fields: Silicon oil's anti -adhesive principle silicon oil, especially die metal silicon oil, can effectively prevent the adhesion of material with its excellent lubricating performance and low surface tension. The free rotation of its methyl group enables the silicon oil molecules to be arranged in an orderly and densely on the surface, forming a layer of low -energy surface, thereby reducing the interactive force between material and achieving anti -sticking effect.

Silicon oil can not only be used alone, but also can meet different industrial needs by formulating solutions, lotion, qi mist or fat ointment.

The application field of silicon oil in anti -adhesives

1. The food industry

 Silicon oil is used as anti -adhesives for packaging materials and cooking utensils, such as French fries to prevent food from sticking to the pot. It can also ensure the hygiene of food processing, because silicone oil is non -toxic and has good chemical stability.

2. Paper Industry

Organic silica oil has become excellent paper anti -adhesives with its unique performance. Its armor is very extremely extremely polar, low surface tension, and low -energy surfaces can be formed after coating, which effectively prevent adhesive molecules from penetrating into the paper base.

Silicon oil anti -adhesives need to be crosslied after coating to form a mild network structure, thereby maintaining a long -lasting anti -adhesive effect.

3. Rubber and plastic industry

Silicon oil is often used as a Democratic agent of rubber and plastic products for molding. Due to the non -stickiness of these materials, the prolapse process becomes easy and the surface of the product is clean and smooth.

In precision casting, silicone oil can also play an excellent anti -sticking effect.

4. Chemical and textile industry

In the field of chemical industry, when silicon oil is used as a foaming agent, it can eliminate the foam and prevent foam from regenerating. Its anti -sticking characteristics help prevent the accumulation of foam in equipment and pipelines. In the textile industry, silicone oil can be used for fibrous treatment agents, improves the smoothness and wear resistance of fibers, and reducing the adhesion between fibers. Fibrous fibrous filament and original cotton oil: Low viscosity dioma silicon oil is widely used as oil agents due to the characteristics of temperature resistance and unchanging color. Textile oils: combined with anticurping agents, emulsifiers, etc., oil preparation of di metharilic silicon oil and methamphetamine silicone oil, used in the spinning process of nylon, polyester, spandex and other synthetic fibers to effectively prevent interruptions. Silk and loose phenomenon.

5. Electronics and optical industry

In the manufacturing and maintenance of electronic equipment, silicon oil is used as an insulation and lubricant to prevent short circuit and adhesion between electronic components. In the cleaning and maintenance of optical lenses, silicon oil can provide a smooth film to prevent the adhesion of dust and stains.

6. Biotechnology field

In the field of biotechnology, silicone oil is used to separate biomolecules such as DNA and protein, and as lubricating and anticurious agents in cell culture and biological reactors.

7. Application of metal casting

Dallery processing: During the melting spinning process, the dioma silicon oil is used for the launching processing of the nozzle to prevent carbides or molten attachment, thereby avoiding broken silk.

The advantage of silicon oil anti -adhesive

Non -toxic and harmless: Silicon oil is mostly non -toxic or low toxic, which meets food safety and environmental protection requirements. Good chemical stability: It can maintain its performance stable under various environmental conditions. Easy to process: Silicon oil is easy to formulate and use, which can meet the anti -sticking needs in different fields.

Silicon oil is used as refrigerant

Silicon oil can be used as a refrigerant or as part of the refrigeration system under certain conditions and application scenarios, but its main use is not directly used as traditional refrigerants, such as Freon or ammonia. The application of silicon oil in the field of refrigeration is mainly reflected in the following aspects:

1. As a heat transfer medium in the equipment such as frozen dryers, silicon oil is often used as heat transfer medium. In these devices, the compressor does not directly refrigerate the product. Instead, it cools the silicone oil by the heat exchange device, and then the silicone oil circulates to the product to cool the product. During the temperature of the drying stage, silicone oil also plays a role in conveying thermal energy. This application method uses good thermal stability and liquidity of silicone oil, making the cooling and heating process more efficient and uniform.

2. As a refrigerant ingredient or additive, although silicon oil is not directly used as a refrigerant in the traditional sense, some silicon hydrocarmical compounds, such as chain silicone hypalide, nails siliconxyl three (triangular silicon oxygen) silicane, because it Excellent physical and chemical properties (such as chemical stability, non -toxicity, high boiling point, suitable for low temperature environment, etc.) are studied and applied in the field of refrigerant. These Siliconane hypalide can be mixed with other ingredients to form a mixture with a specific refrigeration performance for applications such as frozen oil to improve equipment efficiency and life.

3. The application in the refrigeration system is used in a complex refrigeration system. Silicon oil may also be used as lubricants or sealing agents to reduce friction and wear between mechanical components and improve the sealing performance of the system. Although these functions are not directly involved in the refrigeration process, it is essential for maintaining the stable operation of the refrigeration system and extending the service life.

4. Special applications in some special application scenarios. If the temperature -transformer testing device under neutron diffraction, silicone oil is used as a circulating medium for the temperature control system. Through the circulation and temperature control of silicone oil, the temperature of the test material is loaded and temperature control. This application method uses good thermal conductivity and controllability of silicone oil to facilitate scientific research and testing.

5. Advantages and limitations: As a part of silicon oil as a refrigerant or refrigeration system, it has the following advantages:

Chemical stability is good, it is not easy to decompose or has high heat stability, and can maintain stability in the wider temperature range;

Good liquidity, easy to circulate and heat up:. It is friendly to environmental, non -toxic or low toxic. However, silicon oil also has some limitations, such as relatively high costs, and refrigeration efficiency in certain application scenarios may not be as good as traditional refrigerants. Therefore, when choosing to use silicone oil as part of the refrigerant or refrigeration system, you need to make comprehensive consideration according to the specific application scenarios and needs

6. Other applications
