及びその製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention provides a method for retarding reactivity or solubility with water or an aqueous liquor/alkali solution. 'Regarding a composition and a method for producing the same,
In particular, the coating material for reliable controlled release at low cost is based on wax with a melting temperature of 40℃ or higher, and has an appropriate balance of affinity with the core material and water at a ratio of 1:1. The present invention relates to a wax-coated composition in which a core material which reacts or dissolves in the melt thereof is dispersed therein, and a process for producing the same.

題がある。However, although many of these have high reactivity or solubility and are fast-acting 1), they often cannot be visited during use, causing operational and process control problems when manufacturing products. Alternatively, there is a problem that the reaction cannot be sustained for a long time because gas generation and exothermic rate are fast.

ている。For example, if you sow carbide and water in a pineapple,
) There is a known method for promoting the growth of pineapple with Ab1None, but since the reaction f1 of carbide is high, it is effective immediately after sowing +F4, and in addition, the promoting effect is effective. It is said that if you sow 4J in the evening or at night, it will not produce any results. Therefore, there is a demand for a carbide that has a pot life from when it is sown to the time when acetylene is generated, and also has a sustained release property that generates acetylene for a long period of time.

覆ることで調節できる。Cover a substance with a width of fatty acid of 1 second or more. Water is prevented from contacting the core material by this coating material. The contact time is controlled by the hydrophobicity ratio of the coating material, the rα ratio of the coating, and the physical properties and particle size of the additive composition which will be described later to determine the hydrophilicity fNl':3. That is, the more hydrophobic the material is coated, the longer the delay time until the core material reacts or dissolves upon contact with water. For example, if paraffin and alcohol have the same number of carbon atoms, paraffin will last longer by y. It can be adjusted by mixing and covering these appropriately.

By adding appropriate amounts of these, the molten dispersion system can be stabilized, spraying becomes easier, coating is uniform, and the wettability of the coating material to water is improved.
