تفاصيل المنتج

Ethylene glycol, also known as ethylene glycol, 1, 2-ethylene glycol, referred to as EG, is the simplest diol. Ethylene glycol is colorless, odorless, sweet liquid, low toxicity to animals, ethylene glycol can be miscible with water and acetone, but the solubility is small in ethers. Used as solvent, antifreeze and raw material for synthetic polyester. The high polymer polyethylene glycol (PEG) of ethylene glycol is a phase transfer catalyst and is also used in cell fusion. Its nitrate is an explosive.

طلب

1. Lubricant: Ethylene glycol can be added to lubricating oil as a lubricant to provide better lubrication effect. It has good lubrication performance and low viscosity, which can reduce friction and wear and extend the service life of mechanical equipment.

2. Coolant and antifreeze: EG is often used as an ingredient in engine coolant and antifreeze. It has a high boiling point, low freezing point and good thermal conductivity, and can effectively absorb and release heat in the cooling system of vehicles and industrial equipment, preventing the coolant from freezing and causing damage to the cooling system.

3. Reaction medium: chemical ethylene glycol is widely used in chemical synthesis. It can be used as a solvent or reaction medium for the preparation of catalysts, the synthesis of polymers and the reaction of organic compounds.

4. Dehumidifier: Because ethylene glycol is hygroscopic, it can be used as a dehumidifier to reduce humidity in the air, maintain humidity stability and prevent corrosion or mold growth in humid environments.

5. مستحضرات التجميل ومنتجات العناية الشخصية: Ethylene glycol is used as a solvent, thickener and moisturizer in cosmetics and personal care products. It can increase the viscosity of products, improve the moisturizing properties of the skin, and enhance the quality and application experience of cosmetics.
