Choose the antifreeze equipment considerations

by:Arkool     2020-08-09

Production of antifreeze need choose normal manufacturer of equipment, using the normal formula, to produce products that meet the quality requirements. Should call the full name of antifreeze antifreeze coolant, meaning anti-freezing function of cooling fluid. Antifreeze can prevent the freezing cold winter parking coolant and burst radiator and freezing the engine cylinder block or cover.

 Many people think that use fangdongye only in the winter, but we have to correct the misunderstanding, in fact, antifreeze is not only in the winter, it to use all year round. 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 40' The following C. To keep the water tank and cooling system pipe from frost crack, antifreeze should not freeze or solidification under this temperature, lest produce volume expansion, at the same time ensure ready to start the car, put into use. 2, higher specific heat and thermal conductivity of antifreeze are mainly used for cooling the engine parts, lest produce heat, so its specific heat. The specific heat of water is 4. 18· C, and the specific heat of ethylene glycol is 2. 72 j / 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. 

 Antifreeze to respond to these metal does not produce corrosion and rust. 4, in use to keep a certain PH PH value can not only ensure the antifreeze to minimize the extent of corrosion of metal, and can prevent corruption in antifreeze metamorphism. In addition, antifreeze should have excellent defoaming performance, air release properties and recycling aluminum pump cavitation does not occur, as well as low price, no special smell, etc. Fangdongye directly affect the performance and service life of automobile, the best in the four seasons are used. If you want to buy automobile antifreeze, choose regular brand products, it is best to the credibility of good auto parts store and repair shops to buy, to ensure that the purchase to the normal manufacturer production of qualified products.
