Coating film plus potassium urea and preparation method thereof

Abstract: The coated potassium plus urea and its preparation method involve an improvement of the existing chemical fertilizer and its manufacturing process. The composition of the coated potassium-added urea according to the present invention contains urea 55-70%, potassium chloride 25%-35%, organic matter 5-10%; the outer surface of the product is coated with the above ratio of 100 % of the pest control organic oil 0.2-0.4%, resin film 0.4-1.3% envelope. The preparation method mainly comprises mixing the above components into a granulator, granulating at 3-5 minutes and 38-54 ° C, and drying at 55-88 ° C; the ratio is 100%. 0.2-0.4% of the pest-preventing organic oil and 0.4-1.3% of the resin film are mixed into a coating agent, and coated at 2-4 minutes and 50-60 °C. The product of the invention can greatly reduce the production cost and labor intensity and improve the yield and quality of agricultural products while greatly improving the fertilizer efficiency.

Application of Geotextile
Filtration
It can be the filtration layer of the dykes, river canal, seacoast, concrete slope, retaining walls. At the same time of preventing the clay granule from passing, it allows the water and the gas pass through freely.
Separation
The isolation of the railway dregs and the roadbed, roadbed and the soft base, surface of the airdrome and parking lot and the groundsill, different dam materials. It isolates the soil and the gravel of two kinds different
granule pathway from the groundsill or other buildings. 
Reinforcement
The highway, railway, soil-stone dam, breakwater, airport, backfill soil of retaining wall, slope protection, etc in which distributes the earth stress, prevents the side-displacement of the earth body and improves the earthbody stability. 
Protection 
It prevents the bank from being washed out, protects the bank and the
bottom, prevents the water and soil from being washed away.
