Performance and Application
1. Phosphate esters are of great significance as emulsifying stabilizers in the spinning process of fiber fabrics, especially under high alkalinity conditions, and are also an important component of synthetic fiber finishes.
2. Phosphate esters have the function of preventing electrostatic accumulation and promoting rapid electrostatic discharge in the papermaking, plastic, and leather industries, making them widely used as antistatic agents for highly hydrophobic and hydrophilic systems. In addition, phosphate esters have a wide range of acid, alkali, and salt resistance abilities, and can be used in chrome tanning or chrome retanning in leather processing. This makes the distribution of chromium salts more uniform within the leather and allows the chromium salts to combine with the leather, resulting in a "permanent" fatliquoring effect.
3. In energy and building materials, phosphate esters as additives for automotive and automotive fuels can improve the combustion value of oil products and reduce energy consumption. Used as a stabilizer in polymer materials, it can be used to prepare phosphate glass. A coupling agent suitable for processing fillers such as calcium carbonate.
4. Among processing aids, phosphate ester is a multifunctional plastic processing aid. Due to its excellent plasticity, stability, heat resistance, anti-static properties, pollution resistance, and transparency, it has been widely used in plastic products for buildings, furniture, mines, conveyor belts, and transportation components.
5. In addition, phosphate ester salt has excellent lubricity, corrosion resistance, abrasion resistance, anti-static property, low friction, emulsification, welding resistance, etc. It can be used as cutting oil, wire drawing oil, etc. It can also be prepared into oil soluble and water soluble lotion, and also has corrosion inhibition performance.
