From the SEM observation of the cross section of the coating material, the thickness of the resin film was about ·· from the resin coating amount of the step. The dissolution behavior of IS plutonium at 25 deaths was evaluated for the bark-coated granular fertilizer prepared by the above procedure. Result • The coated urea dissolved 80½ fat components in about 85 days. It was confirmed that it had sufficient efficacy. And the evaluation of fertilizer dissolution is based on the method proposed by the Japanese Ministry of Agriculture, Forestry and Fisheries Research Institute of Environmental Technology (for example, "(Please read the precautions on the back before filling out this page), ... ia--this paper size Applicable to China National Standards (CNS) Λ4 specifications (210X 297 mm) 386 36 464640 Economic cooperation between the Central Bureau of Standards and Labor of the People's Republic of China printed A7 B7 V. Description of the invention (8) Detailed fertilizer analysis method " 1988) Real Sfc. When the bottle W 2 was used, 2 kg of granular urea (average particle size 3.4 · β) was exactly the same as in Example 1 to make it into a rotating state * and maintained at 6 5 to 7 0 X1. On the other hand, the coating resin uses the same ingredients and composition ratios as those in Example 1. First add the amine catalyst 0.U to 5.3g of the multi-enzyme ingredient and mix thoroughly. • Add to the granulated bark material in the rotating and warming bark state. Polyamines containing amines can be visually observed to cover the surface of the fertilizer uniformly in about 30 seconds. After that, 4.7g of polyisoacid® was added while maintaining the rotation and heating of the fertilizer. After adding the polyisocyanate component • When taking out a part of the sample 3 minutes later • The resin is almost in a state where drilling properties are lost. The above steps were repeated 16 times every 4 minutes * The fertilizer was covered with 8% by weight. The fat dissolution behavior of 25 C fertilizer was evaluated in the same manner as the butter-coated granular bark fertilizer prepared from the above steps and buttercup example 1. As a result, the coated urea dissolved 80¾ of fat content in 妁 85 days, and confirmed that it had sufficient effectiveness. In addition, according to the actual examples, it was confirmed that the method of separately adding a polyisocyanate component and a polyzyme component is also feasible. In Example 3, 2 kg of granular urea (average particle size 3.4f * in >) was made into a rotatable state in exactly the same manner as in Example 1. It was kept at 6 5 ~ 7 0 t1. The coating resin was cured and cured. Example 1 has exactly the same composition and ratio. 15 g of the coating resin that has been fully hardened and uncoated is added to the granular fertilizer that is in a heated and rotating state * and is coated with a urethane resin. The resin is 0.75% by weight. The size of the coated fertilizer has a quiet shape.

Description of the invention (9) The resin film thickness is about 4.3 ^ ·. It can be confirmed by visual observation that the resin that has been injected is approximately uniformly coated on the surface of the granular fertilizer in about 30 seconds. About 3 minutes after the resin was put in. • A part of the sample was taken out. • The resin was in a state of almost losing its adhesiveness. The above steps were repeated 16 times every 3 minutes, and the fertilizer was coated with 12% by weight. Finally, (c u t c i a y) 1 0 s is added, and a 10-minute gun is held at 70 to 75C. A carbamate-coated granular fertilizer is obtained. For the resin-coated granular MG prepared by the above procedure, the dissolution behavior of 25T1 fertilizer was evaluated in the same manner as in Example 1. As a result, 80% of the fertilizer which was dissolved by S urea in about 85 days * was confirmed to have the slowing effect of a foot dog. bh Example 1 Except that the amount of resin added at one time was 40 g%, and the rest was exactly the same as that of Cell Example 1. An attempt was made to manufacture a resin-coated fertilizer. The amount of the resin was 12.4 wm for the granular fertilizer. Visual inspection method • It can be confirmed that the injected resin covers the surface of the granular fertilizer in approximately 30 seconds. After about 2 minutes, the resin will thicken and have "shadow resistance". • Particles will stick to each other to form agglomerates of a large number of particles. After that, they will not disintegrate. 'hh 舲 Example 2 Except for the resin component without the addition of an amine catalyst * Except for the same method as in the case of the real cell example, the trial-manufactured resin-coated target was manufactured without the addition of an amine catalyst * The gel time of the resin was 20 minutes * When the sample was taken out 3 minutes after the first fat application, the resin did not harden and remained liquid. Also, the sample was taken out in the same manner after 0 minutes *. The resin thickened cobalt was called bark fluid hip. In this state, the same filling performance of the fertilizer is added with resin and particles are adhered to each other.
