Description

[Detailed description of the invention] [Purpose of the invention]

[Industrial Application Field] The present invention relates to compositions for spraying such as oxygen scavengers, deodorizers, preservatives, fungicides, agricultural chemicals, or fertilizers. [Conventional technology] Conventional powdered pesticides for spraying include talc, calcium carbonate,
It is usually adsorbed onto a porous carrier such as gypsum and then dispersed using a powder duster (or, on a large scale, from a helicopter). Although this method is labor-saving and effective, it does not eliminate concerns that the sprayer may be poisoned or the spray may be blown away by the wind and cause environmental pollution. On the other hand, hand-spreading is a relatively safe method.
It is labor intensive and has the disadvantage that it is difficult to spray uniformly. [Problems to be Solved by the Invention] Therefore, the problems to be solved by the present invention are mainly suitable for small-scale manual spraying of oxygen absorbers, deodorizers, preservatives, fungicides, agricultural chemicals, fertilizers, etc. It is an object of the present invention to provide a composition for spraying that can make the spraying density relatively uniform without the risk of being inhaled by a sprayer.

[Structure of the invention]

Means for Solving the Two Problems] (1) Concept The present inventor has solved the above problems related to the manual spreading of deodorizers, preservatives, agricultural straw, fertilizers, etc. Moreover, as a result of studying the composition of a spraying agent that can be easily and evenly distributed by hand, the present invention has been arrived at. (2) Overview That is, the present invention is a composition comprising a granular carrier supporting a material to be dispersed and having a macroscopic size that is not blown away by ordinary wind, the granular carrier comprising at least two particles. The gist of the present invention is a composition for dispersion characterized by comprising small specific gravity particles and large specific gravity particles of seeds. Hereinafter, various elements constituting the invention will be explained in terms of sections. (31 Types of granular carriers In the present invention, granular carriers refer to macroscopic granular substances with a specific surface area that are suitable for supporting the following substances to be sprayed, etc.) 7 Typical examples of granular carriers For example, sintered alumina, silica gel, pearlite, Akadama clay, calcined zeolite 1 or calcined zeolite, granular expanded slag,
In addition to artificial granules such as copper, coarsely crushed coke, pulp powder, activated carbon, and charcoal particles, vermiculite, ready-to-grain clay,
Examples include porous particles derived from natural products such as diatomaceous earth or hentonite, crushed pumice, coarse grains of maifanite, crushed lava, coarsely crushed bulk or peat moss, rice husk charcoal, and sawdust. (4) Size and bulk specific gravity of granular carrier For the purpose of the invention, at least two or more of the above granular carriers are used as a mixture. The first carrier is of a type having a relatively low specific gravity. The second carrier, on the contrary, has a high specific gravity. - For boat fishing, it is preferable that the small specific gravity particles have a larger particle size than the large specific gravity particles. The size of these particles should be macroscopic enough that they will not be blown away by normal winds that may be present during dispersion; selected from things. Furthermore, it is difficult to absolutely define the specific gravity of the granules, or the first granules preferably have a bulk density of less than 1, preferably less than 0.8. However, ultra-light particles with a bulk density of less than 02 may be blown away even by a slight breeze, so they are not suitable for use with large amounts of components. The various granular carriers mentioned above are classified as follows based on the bulk density of 1.0 and 0.2. Bulk density 1.0 or more (heavy granular carrier); sintered alumina, calcined zeolite, synthetic zeolite, copper entangled. Bulk density less than 1.0 (light granular carrier) Nijirica gel, perlite, Akadama soil, calcined zeolite or synthetic zeolite,
Granular expanded slag, coarsely crushed coke, activated carbon, vermiculite, granules (Hifurei, diatomaceous earth or hesitone 1~, crushed pumice, coarse grains of maifanite, coarsely crushed lava, charcoal grains. Bulk density less than 0.2 (ultra light granules) Carrier) Pulp powder, coarsely crushed bulk or peat moss, rice husk charcoal, sawdust. (5) Combination The above-mentioned heavy granular carrier and light carrier (and optionally ultra-light carrier) may be mixed as appropriate while supporting the material to be sprayed as described below. It is blended in the proportion of The blending ratio at this time may be appropriately determined depending on the bulk density and particle size of the carrier;
: It is blended in the range of 50. By adding a small amount (within 20%) of an ultra-light carrier, the density at the time of dispersion can be more evened out. By coloring the carrier to change its color as desired (of course, if the color of the carrier itself is different, leave it as is),
The uniformity of the distribution density can be confirmed with the naked eye. (6) Spreading material The material to be spread carried on the granular carrier of the present invention includes:
Examples include, but are not limited to, oxygen scavengers, agricultural chemicals (bactericides, insecticides, plant growth regulators, etc.), fertilizers, etc. Note that the present invention can also be used when it is desired to uniformly disperse small seeds such as rapeseed, top, tobacco, grass, and orchid. The above-mentioned materials to be spread are determined according to the nature and characteristics of the materials to be
It is mixed with the above carrier in the form of a solution, suspension, fine powder, or as it is, and dried if necessary. When the object to be dispersed is a relatively large object such as a seed, a small amount of glue may be added, if necessary, for the purpose of ensuring reliable adhesion to the carrier. [Function] In the spraying agent according to the present invention, heavy granular carriers and light granular carriers are mixed, so when this is sprayed, the heavy carriers fall within a narrow range, and the lighter carriers fall into a smaller area. Fall within a wide range. In particular, when the spray opening is point-shaped, heavy carriers mainly fall in a conical shape with a steeply sloped slope relative to the horizontal plane (spreading surface), whereas light carriers fall mainly on a slope or gently sloped. Since the particles fall in a conical shape, the dispersion surface of the former (bottom of the cone) is larger in diameter than the dispersion surface of the latter. Therefore, if the particle sizes and densities of the two types of carriers are properly determined, an average density distribution can be obtained over the spray area. The more varied the densities of the carriers that make up the composition, the more average the distribution density will be. The above-mentioned spraying effect is best achieved when the agent is shaken out from a narrow spray opening, as in the case of furikake, but the same effect can be expected even when the agent is squeezed by hand. . [Examples] Hereinafter, embodiments of the invention will be explained using Examples, and the examples are merely for explanation and do not mean any restriction or limitation on the idea of the invention. Production example: Calcined hard zeolite (average particle size Q, 5~L5''/
Wow. Average bulk density: 1.4>100 parts by weight (the same applies hereinafter) and calcined diatomaceous earth (average particle size: 1.0"/, average bulk density: 0.
8) and 100 parts were intimately mixed in a small concrete mixer. At this time, gradually sprinkle 4 t) Part Q of an aqueous solution containing 1100 ppm of ascorbic acid and 214 ppm of fine particulate iron, completely mix the acid, and dry with hot air while stirring to form a granular deodorizing composition for spraying of about 201 g. I got the department. Usage Example 1 The composition of the production example was placed in a paper carton with a small hole of 2 ml in inner diameter, and a 4-month-old kitten (native species, male 2, weighing approximately 2.2 kg) regularly used it as a toilet. In a planter filled with horticultural soil (commercially available mixed culture soil as ``Hana no Soil''), the entire top is cut back five times with a shovel every morning, and the above composition is added to the surface of the soil that has been cut back. The operation of evenly distributing the powder to a thin layer on the soil surface was repeated. Note that feces were removed by scooping in advance. Seven days after the start of the experiment (October 1st) when fresh soil was added, an ammonia odor was felt during the first cutting, but it disappeared after cutting and spraying the above composition.
Approximately 5 cm from the soil surface even after January has passed since the start of the experiment.
Almost no ammonia odor could be detected even at such depths. Incidentally, the average maximum temperature during the experiment period was about 22°C, which was sufficient for soil microorganisms to reduce urea and uric acid in urine to ammonia if the above composition were not present. In addition, the soil after the experiment contained a sufficient amount of nitrates, and flower petals,
Suitable as culture soil for vegetables. Use Example 2 Starting from the beginning of August, the composition of the above-mentioned production example was poured into a plastic bag every day for 7 days, each time a Log amount of garbage was poured into the plastic bag, followed by spraying. As a control, a control group was set up in which the above composition was not added at all. The food waste bags in the test area in which the above composition was added had almost no off-odor even after 7 days, but in the control area, the off-odor began to develop after 2 days, and after 3 days, the off-odor became noticeable, so the experiment was discontinued. did.

【Effect of the invention】

The spraying composition of the present invention provides a means for uniformly spraying the composition onto a target surface without the risk of inhaling the carrier agent during simple spraying by hand, etc. It is highly effective for spreading and applying fertilizers, etc.
