There is no shortage of urea in life and we all know that the use of urea is a necessary product for heavy diesel fuel. Urea is the best choice for reducing emissions in China. The special raw material for vehicle urea is also known as urea which is the raw material for the high difficulty vehicle urea solution.
Urea is a urea water solution with a concentration of 32.5% and a solvent of ultra-pure water with urea crystals and ultra-pure water. Although the purity requirement of the vehicle is higher than that of the general industry the domestic technology can meet the practical application requirements. The production process of urea is not enough to construct high barriers to entry.
Purification of urea is urea mainly from domestic automotive industry in the temperature 70-75 ℃ the hydrolysis of urea occurs in aqueous solution. When the temperature below 30 ℃ urea crystallization from aqueous solution. The purity of each hydrolytic crystallization can be greatly improved and it can be used to meet the standard requirements of urea in automobile. Because the SCR catalyst carrier is extremely easy to cause metal ion intoxication and lose the catalytic effect the urea solution must be used in the electronic industry.The vehicle that chooses SCR technology must add urea solution as the catalytic reducing agent to make the vehicle meet the standard emission.
At present the production of urea in domestic vehicles is dominated by small and medium-sized private enterprises which can meet the new nitrogen oxide emission standards and the automobile urea is constantly optimized to meet the needs of the development of the industry. The car urea always insists on the product quality to win the market and brings more guarantee for consumers.
Yongjia county jia and machinery co. LTD. Specializes in the production of urea refueling machine air gun mini refueling machine stainless steel refueling gun vehicle refueling machine and other refueling station equipment. Product quality reliable durable reasonable price.
