Types of car antifreeze
There are many types of automobile antifreeze, such as calcium chloride (CaCl2) in inorganic substances, methanol (CH3OH) in organic substances, ethanol (C2H5OH, common name alcohol), ethylene glycol (C2H4(OH)2, common name sweet alcohol), Glycerol (C3H5(OH)3, commonly known as glycerin), lubricating oil and the common sugar and honey in our daily life can all be used as the mother liquor of antifreeze. After adding appropriate amount of pure soft water (without or a small amount of calcium, magnesium) Ionized water, such as distilled water, unpolluted rainwater, snow water, etc., can become an antifreeze in a general sense after the total hardness component concentration of the water quality is between 0-30ppm.
