To convert between Ammonia Value (AV) and Nitrogen Content, the core lies in establishing a quantitative relationship between "the neutralization capacity of free ammonia (NH₃)" and "the mass of nitrogen element in free ammonia". Before conversion, it is necessary to first clarify the definitions, units, and applicable premises of the two, and then derive the conversion formula based on the chemical equivalent relationship.

As a type of non-curable silicone oil, conventional linear dimethyl silicone oil (i.e., ordinary polydimethylsiloxane, PDMS) has inherently different core properties from curable systems. Although it cannot form a cured film with a three-dimensional network structure through chemical reactions, its unique physicochemical properties still make it irreplaceable in specific scenarios. The following analysis is carried out from three dimensions: technical principles, performance boundaries, and typical applications.

mino-modified silicone oil is fully suitable for functional finishing of down jackets. The amino groups in its molecular structure can form strong bonding with active groups (such as hydroxyl and carboxyl groups) on the surface of down fibers (protein fibers) and fabric fibers (e.g., nylon, polyester, and other synthetic fibers), forming a uniform flexible film on the fiber surface. This simultaneously achieves the three core functions of softness, antistatic property, and bulkiness. Below is a detailed analysis and parameter recommendation:

The application of amino silicone oil on aramid fibers (such as Kevlar) is mainly to improve their surface properties (such as lubricity, softness, antistatic property, etc.) without damaging the core characteristics of aramid, such as high strength and high temperature resistance. The following are the formula design principles, typical process steps and precautions for aramid fiber treatment with amino silicone oil, for reference:

When using amino silicone oil to produce brighteners, the suitable viscosity range is typically between 500 - 5000 mPa·s. The specific analysis is as follows:

Amino silicone oil has a certain antistatic ability (dependent on humidity), but it is usually used as an auxiliary function and has limited effect when used alone. Incorporation of quaternary ammonium salts is an effective means to improve antistatic performance. Chemical modification (molecular incorporation) is better than physical compounding, which can achieve a long-lasting and efficient antistatic effect while retaining the softness of silicone oil. Application suggestions: Select the modification method according to specific needs (such as chemical modification is preferred for durability needs), and balance antistatic properties, stability and other functions (such as softness and yellowing resistance) through formula optimization.

Dimethyl silicone oil is a non-polar inert liquid that is difficult to dissolve in water. When cleaning, you need to use its properties of being soluble in organic solvents or emulsified by surfactants. The following are cleaning methods for different scenarios, which need to be selected according to the floor material and available materials:

Silicone oil, also known as silicone or polydimethylsiloxane, refers to polydimethylsiloxane and its derivatives. It belongs to high molecular weight polymers and is a type of non greasy synthetic oil and wax. In cosmetics, it is widely used as a high-quality oily raw material. It has excellent physical and chemical properties.

With the rapid development of electronic products, silicone potting glue is increasingly used in electronic products. Silicone potting glue is a liquid glue poured on electronic components. It can provide excellent heat dissipation and flame retardant properties for electronic components. It can also effectively improve the shock and moisture resistance of electronic components and ensure the stability of electronic components. The performance of silicone potting glue is very important for electronic products. So what are the important indicators for measuring the performance of silicone potting glue? Please see the following explanation.
