Wei Connaught Chemical, Shandong glycol suppliers, ethylene glycol market, ethylene glycol is provided by Wei Connaught Chemical. We are Qingdao Wei Connaught Chemical Co. (www.qdweinuo.com) at: Qingdao, Shandong specialized in: phenol, aniline, ethylene, n-butanol, isobutanol, n-propanol, isopropanol, methanol, ethylene glycol DME is an excellent product performance higher organic solvent as a printing ink, industrial cleaning agents, paints. GB polyester grade glycol is mainly used for manufacturing polyester polyester, polyester resin, hygroscopic agent ethylene glycol, plasticizers, surfactants, synthetic fibers and cosmetics. Ethylene glycol antifreeze can be used, in addition to the supply of ethylene glycol used as automotive antifreeze, but also for industrial cooling capacity of transport, general call for secondary refrigerant. Like ethylene glycol and water can also be used as condensing agent. Other effects of ethylene glycol specific detailed advice can promise Qingdao Wei Chemical. Ethylene glycol is a colorless, slightly viscous liquid, the boiling point is 197.4 ℃, freezing point is -11.5 ℃, can be mixed with water in any proportion. After mixing of the cooling water due to changes in the production of ethylene glycol vapor pressure significantly lower the freezing point. Degree of reduction within a certain range with the content of the ethylene glycol increases. When the content of ethylene glycol is 60%, the freezing point can be reduced to -48.3 ℃, this limit is exceeded, but to the freezing point of the rise. Glycol antifreeze easy to generate, in use, the acidic substance, a pair of metal corrosion. Glycol toxic, but because of its high boiling point, does not produce vapor being inhaled and cause poisoning. Glycol absorbent, storage containers should be sealed glycol market, after to prevent water overflow. Since the boiling point of water is lower than ethylene glycol, the use of the water is evaporated, when a lack of coolant, just add water purifier on the line.
