The Weifang Tainuo chemical industry Limited company is located in “the world kite” - - Weifang, south near the rubber Jinan railroad, north depends on 309 federal highways, the blue silver highway, the geographical position is superior, the traffic conditions are convenient. in 2006 sets up with joint forces by the original Shandong four stars in the bowl of the big dipper specialized team, is domestic devotes to the development green environmental protection safety product for the mission specialty company.
After more than 100 years of development of Fertilizer, the direction of Fertilizer technology innovation has been established. Next, let us take a look at the technological approach to Fertilizer innovation.
Fertilizer is often used in our daily production and life, so what are the problems faced by the utilization of Fertilizer in China's planting and breeding industry? Let's see together.
China has a vast territory, and although the natural conditions, planting methods, and scale of livestock and poultry breeding vary greatly among regions, the utilization of Fertilizers for planting and breeding waste is mainly divided into direct utilization and indirect utilization according to the method of returning to the field.
As an indispensable means of production for modern agricultural production, Fertilizer is currently in an unprecedented stage of innovation and development in my country's Fertilizer industry. New formulations, new technologies, and new products are constantly emerging revolution in the Fertilizer industry. However, many factors affect the innovation of Fertilizer in our country, and the interference of these factors should be avoided, and advantages should be avoided.

Most diesel vehicle manufacturers often use AUS32 as a reducing agent. The concentration of Urea Ad-blue directly affects the reduction rate of nitrogen oxides and the crystallization point of urea solution. If the concentration is too high or too low, it will not only improve the conversion efficiency of nitrogen oxides, but will cause secondary pollution of the remaining ammonia gas. The concentration of 32.5% was chosen because Urea Ad-blue has the lowest crystallization point at this concentration (freezing point -11 ° C).
Urea Ad-blue needs to avoid impurities entering the solution and urea tank during the filling process. In general, Urea Ad-blue has a special tube when it is filled. Just open the urea tank and insert the filling tube. However, some people usually pay little attention to bring impurities into the tank and block the urea tank urea pump. In order to prevent impurities, pure water must be used to clean the SCR, and tap water is not available.
Urea Ad-blue is alkaline and is highly corrosive to copper, cast iron, solder and cast aluminum. Improper filling can contaminate tanks and vehicles.
In addition, since Urea Ad-blue itself has no major harm to the eyes and skin, it also causes slight irritation to the human body. If in contact with the skin, rinse the exposed skin with plenty of soap or water. If it comes into contact with the eyes, open the upper and lower eyelids and rinse with water.
Urea Ad-blue needs to be protected from light and heat during transportation. The optimum transport and storage temperature should be between -5 °C and 25 °C. In addition, Urea Ad-blue crystallizes when the temperature is low, and the volume expansion becomes as large as 7%. If it is too full, it remains below 90% of the storage volume ratio. High temperatures can cause the decomposition of Urea Ad-blue, which is generally associated with storage temperature and storage time.
