Car urea is an essential product for heavy-duty diesel vehicles to meet the National IV emission standards. Vehicle urea refers to an aqueous urea solution with a urea concentration of 32.5% and ultrapure water as the solvent. The raw materials are urea crystals and ultrapure water. For diesel vehicles such as heavy trucks and passenger cars to meet the National IV emission standards, a suitable SCR system must be selected for exhaust gas treatment, and this system must use urea solution to treat nitrogen oxides in the exhaust gas.
Special combination instruments, such as Kjeldahl trace nitrogen analyzer, K-D evaporation concentrator, rotary evaporation concentrator, etc., should be cleaned and protected.
