Wei Connaught Chemical, Shandong Glycol Suppliers | glycol Company | glycol 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 why displayed low freezing point of alcohol? There are a lot of people think that low freezing point of ethylene glycol company, the freezing point of antifreeze is ethylene glycol and water production in accordance with a mixture of different proportions and the freezing point, it is not true, due to changes in the mix after cooling vapor pressure of water, the freezing point will be significantly reduced. After I repeated the test: When ethylene glycol antifreeze and water during each 50% ethylene glycol, antifreeze temperature is -35 ℃: 40% of ethylene glycol and 60% of ethylene glycol antifreeze mixed into soft water market , freezing temperature of -25 ℃. This temperature is sufficient to meet any regional domestic automobile antifreeze antifreeze requirements, as contained refrigerant unit without any problems. There are a lot of people think that low freezing point of ethylene glycol, ethylene glycol antifreeze and water from freezing in accordance with a mixture of different proportions and freezing, it is not true, after mixing due to changes in the vapor pressure of the cooling water, the freezing point will significantly reduced. Degree of reduction within a certain range with increasing ethylene glycol content decreased, but if more than a certain percentage, but will rise in the freezing point. 40% of ethylene glycol and 60% of the water softener mixed into antifreeze, antifreeze temperature is -25 ℃; When ethylene glycol antifreeze and water accounting for 50%, the freezing temperature of -35 ℃
