1) when the temperature of 70-70 ℃, DEF Urea hydrolysis in the aqueous solution attack.
2) under temperature 30 ℃, urea crystallization from solution from the start.
3) every hydrolyzed crystallization, its purity will improve, often using industrial grade urea hydrolysis crystallization, to reach for the urea specification requirements, its share of the output of 1.5:1.

Urea to use electronic automotive professional level of ultrapure water. Automotive urea SCR catalyst carrier is used for metal ion poisoning lose catalytic effect thereby, automotive urea solution to use the professional level of ultrapure water. Vehicle will freeze under 11 ℃, urea solution used in 20 ℃ when frozen. The     skills now is declining after attending modifier freezing point, prevent solution set and heating equipment.
