Meifeng, Sichuan introduced internationally leading Norwegian Drew technology and equipment, and cooperated with China Academy of Agricultural Sciences to build high-end compound fertilizer, which has the advantages of complete nutrients, high content, long fertilizer effect, quick dissolution, easy absorption and high utilization rate. After application, it can effectively improve the imbalance of soil nutrients, improve the ability of crops to resist cold, drought and disease, and achieve significant yield increase.
Process characteristics: The urea-based granulation technology of spray polymerization is adopted. Sulfuric acid and synthetic ammonia react with potassium chloride and monoammonium phosphate to generate salt crystals, and then urea is sprayed evenly, which effectively avoids the increase of biuret caused by secondary heating of urea and affects the product quality.
Main products: meifeng Billy Buddha, meifeng American Xerox, meifeng Bosch, meifeng Wang Defu, Mevles and other products.
Specification: NPK concentration ratio (main formula) is: 15- 15, 16- 16, 17- 17-6558. 20-8- 12, 15- 12- 18, etc. And there are many kinds of models and specifications, such as special fertilizer for fruits and vegetables and BB fertilizer, to meet various customer needs.
Product quality: H20 ≤1.0%; %; Particle size: 2.2 ~ 4 mm ≥ 90%; Particle strength: 30N. Product introduction:
Sichuan meifeng Chemical Co., Ltd. has obtained the international quality system certification, and the melamine plant with an annual output of 6,000 tons is built with Tsinghua University patented technology. Advanced technology, high degree of automation, stable product quality and fine particle size (particle size range 10-20μm). In the application process, it has the advantages of short reaction time, good dispersibility, high production efficiency and excellent quality of reaction products. Molecular formula: C3N6H6, molecular weight: 126.5438+02.
Uses: It is mainly used to prepare melamine-formaldehyde resin, which has excellent water resistance, heat resistance, arc resistance and luster, and can be used as decorative board, aminoplast, adhesive, high-grade paint, coating, general paper reinforcing agent, textile auxiliary, high-efficiency cement water reducer, leather tanning agent, etc. In 2006, meifeng, Sichuan Province took the lead in introducing the international level multi-layer extrusion heavy-duty film bag production line in the domestic plastic packaging industry, which filled the blank of packaging products in the domestic fertilizer industry. After the introduction of the production line, in order to produce satisfactory products to meet the domestic market demand, Sichuan meifeng independently developed the core formula, and all the indicators reached the international leading level. Sichuan meifeng heavy-duty membrane core formula research and development was awarded by the Ministry of Finance. Nominated by China Baolian, the National Development and Reform Commission designated meifeng, Sichuan as the national standard-setting unit for heavy-duty membrane industry.
Advantages of heavy-duty film packaging bags:
Heavy-duty film bag is a new type of packaging with advanced technology, which is formed by three extruders through one mold, multi-color printing, bag making and one-time molding. The three-layer * * * extruded heavy-duty film bag produced and put on the market by Shehong Branch in Mei Feng, Sichuan, has ultraviolet resistance on the surface, adapts to the climatic environment in different regions, and has good temperature and cold resistance; The middle layer ensures sealing and barrier; The inner layer adapts to the physical and chemical properties of the package to ensure its good quality.
Advantages of heavy-duty film packaging bags:
First, the surface is flat, the appearance is beautiful, the pattern content is rich, the image is vivid, the color is clear, and it is anti-counterfeiting; Secondly, it has good sealing, moisture-proof, waterproof and antifouling properties, can be stacked in the open air, is convenient for transportation and storage, can ensure that the fertilizer does not melt, agglomerate, lose weight and have no fertilizer efficiency, and can ensure that the storage shelf life of the fertilizer is twice that of the woven bag; Third, anti-ultraviolet, which can ensure the stability of fertilizer quality and color; The bag will not age and deform. The company specializes in producing plastic woven bags for more than 20 years. The main products are coated woven bags, colored composite bags, cement bags, ton bags and colored striped cloth. The annual production capacity is 6.5438+500,000 tons.
