Why glycol shows low freezing point? There are a lot of people think that a low freezing point of ethylene glycol, the freezing point of antifreeze is mixed in different proportions according to a post and in the freezing point, it is not the chemical ethylene glycol, a mixture of cooling water due to changes in the vapor pressure of ethylene glycol and water glycol market, will significantly reduce the freezing point. After I repeated the test: When ethylene glycol antifreeze and water 50-50 when glycol antifreeze temperature of -35 ℃: 40% of ethylene glycol and 60% of soft water mixed into antifreeze, antifreeze temperature -25 ℃. This temperature is sufficient to meet any regional domestic automobile antifreeze antifreeze requirements, as set coolants do not have any problems. Health hazards: no domestic goods relative to acute and chronic poisoning reported. Acute poisoning was due to more false positives abroad. Inhalation of toxic manifestations of recurrent syncope, and may have nystagmus, lymphocytosis. Acute oral toxicity in three stages: the first stage is mainly the central nervous system symptoms, like light alcohol poisoning, severe convulsions, coma rapidly produce ethylene production, and finally death; the second stage, cardiopulmonary symptoms, severe cases may have pulmonary edema, bronchial pneumonia, heart failure; the third stage mainly for the different degrees of renal failure. This product is a human oral lethal dose is estimated at 1.4ml / kg (1.56g / kg). First aid measures Skin contact: Remove contaminated clothing, rinse with plenty of water. Eye contact: Did eyelid, mobile water or saline. Medical treatment. Ethylene glycol, ethylene glycol chemicals, Wei Connaught Chemical, Shandong glycol suppliers by Wei Connaught Chemical.
