Gufengyuan Fertilizer Co., Ltd. Urea Formaldehyde Sustained Release Compound Fertilizer Project Successfully Drives Once

A few days ago, the urea-formaldehyde slow-release compound fertilizer project jointly developed by Shandong Gufengyuan Chemical Fertilizer Co., Ltd. and the Linyi City Environmental Protection Compound Fertilizer Research Institute was successful at one successful drive, meeting the production standards, increasing production capacity by 20%, and reducing energy consumption by 30%.

It is reported that the successful development of the project achieved for the first time the use of a urea-melting tank for urea and formaldehyde reactions on a conventional drum steam granulating compound fertilizer production plant, using the product urea-formaldehyde solution for agglomerating and granulating of the binding materials, which has been improved. Equipment capacity, reduce material liquid phase, reduce drying load, and reduce energy consumption. Practice has proved that the project has reasonable technology and stable production. It can be easily retrofitted on the existing compound fertilizer production equipment, and has the characteristics of investment, short construction period, low production cost, good economic benefits and broad market prospects.

Urea-formaldehyde slow-release compound fertilizer is one of the earlier slow- and controlled-release fertilizers used in agricultural development. It belongs to the synthetic organic slightly soluble slow-release fertilizer, and its effective nutrient urea formaldehyde is hardly soluble in water, but it can be slowly absorbed and utilized by plants. . It is a series of long-chain condensates such as methylene biurea, trimethine triurea and polymethylurea, which are formed by adding and condensing urea and formaldehyde under certain conditions. It can be slowly decomposed by soil microorganisms to release nitrogen in the soil. The length of the fertilizer effect depends on the length of the urea-formaldehyde component chain of the fertilizer. The longer the molecular chain is, the longer the nitrogen-concentration cycle of the condensate is, and the release period is longer. Up to 120 days to meet a single fertilization without the need for top dressing. The fertilizer can increase production by 20-30% compared with the same amount of normal fertilizer, and can still reduce production without reducing the use of 30%. The fertilizer effect is 1.6-2 times that of ordinary compound fertilizer. The use of this fertilizer can increase the utilization rate of chemical fertilizers, improve the soil environment, and promote agriculture to increase revenue and reduce expenditures. It is an effective way to develop high-efficiency agriculture. The research and development of this fertilizer is in line with the development direction of our fertilizer industry, which can optimize the upgrading of China's existing compound fertilizer industry and ease the pressure on energy and the environment.
