( Laundry detergent production machine) 1, the freezing point and low solidifying point, when the car in the cold region in winter outdoor parking ground temperatures dropped to - sometimes at night Below 40 'C. To keep the water tank and cooling system pipe from frost crack, laundry detergent shall not freeze or solidification under this temperature, lest produce volume expansion, at the same time ensure ready to start the car, put into use. ( Laundry detergent production machine) 2, higher specific heat, thermal conductivity laundry detergent mainly used to cool the engine parts, lest produce heat, so its specific heat. The specific heat of water is 4. 18 kj/kg c. , and the specific heat of ethylene glycol is 2. 72J／kg·℃。 Under the same circulation, water away from the engine more heat than glycol away, so is ideal coolant water. 3, the metal does not produce corrosion and rust engine cooling water system has cast iron, cast aluminum, copper, brass, steel, solder, etc. Laundry detergent to respond to these metal does not produce corrosion and rust.
