(Industrial Application Field) The present invention relates to a water-soluble granular snow melting agent containing carbon black. (Prior Art and Problems) Agricultural work in snowy areas can be started after waiting for the snow to melt in spring, but in regions located in the north, this is extremely slow. Therefore, snow melting agents are used to make up for the delay in starting agricultural work as quickly as possible. The effectiveness of this snow-melting agent has already been proven at agricultural experimental stations and extension offices. Conventionally, as the snow melting agent, fly ash, lignite powder, black stone powder, carbon black, calcium carbonate fertilizer containing carbon black, etc. have been used. After being sprayed, the snow-melting agent is on the snow and absorbs sunlight, increasing the snow temperature on the snow surface and producing a snow-melting effect. The effect is further improved by increasing the temperature of the snow inside. However, the above-mentioned conventional snow melting agents are powder-like and light, and carbon black in particular is a fine powder with an apparent specific gravity of about 0.03 and is extremely light, making it difficult to handle before spraying.
Further, there were problems such as easy scattering even after spraying. Furthermore, the carbon black has a high content of oily carbon and is immiscible with water, so it does not sink during snowfall. Therefore, attempts have been made to granulate carbon black using the general method of mixing it with powder and granulating it and drying it, but as mentioned above, carbon black is an extremely fine powder and light, so it has different bulk specific gravity. Carbon black does not easily enter the powder or granules to be mixed, and as disclosed in Japanese Patent Publication No. 47-30035, as much as 2% carbon black is required to produce a snow melting effect. This 2% is the upper limit allowed by the official standards of the Fertilizer Control Law. Since carbon black is originally a foreign substance in the field and is expensive, it is necessary to use as little amount as possible. Therefore, it has been desired to develop a manufacturing method that enables the production of a granular snow melting agent that has a carbon black content much lower than the conventional one, is convenient to handle, and is easy to sink into snow. (Means and effects for solving the problems) The present invention was developed in view of the above circumstances, and is a granular snow melting agent containing carbon black that eliminates the drawbacks of conventional snow melting agents, is easy to handle, and has a further improved snow melting effect. The object is to provide a manufacturing method which allows mixing and granulation of carbon black to make carbon black. In order to achieve the above object, the present invention mixes calcareous fertilizer and carbon black while crushing them with impact force, then adds and mixes Steffen wastewater concentrate as a granulating agent, and then granulates the fertilizer. And then let it dry,
The amount of carbon black mixed in is 1% or less of the total amount of the calcareous fertilizer, Stephan wastewater concentrate, and carbon black. It consists of: According to the method of the present invention, when carbon black is mixed, the calcareous fertilizer is further pulverized by impact force, thereby reducing the weight difference with the carbon black to aid in mixing, and the carbon black is impulsively brought into close contact with the calcareous fertilizer. Since the mixed state is maintained by using carbon black, even a small amount of carbon black can be mixed sufficiently and uniformly. Here, the mixing accompanied by the above-mentioned impact force is performed using a ball mill.
This can be done using equipment such as a rod mill or hammer mill. Furthermore, general known methods are sufficient for granulation and drying. (Example) Examples of the present invention will be shown below. As the calcareous fertilizer to be mixed with carbon black, calcium carbonate fertilizer, which becomes fertilizer after snow melting, is used. Calcium carbonate fertilizer here refers to calcareous fertilizer based on the Fertilizer Control Law, but it also includes other fertilizers containing lime and industrial by-products containing lime, as well as compound fertilizers based on the Fertilizer Control Law and organic fertilizers based on the same law. There is an effect. Furthermore, the carbon black used is one that is currently commonly produced and commercially available. Furthermore, in the following examples, a Steffen wastewater concentrate (hereinafter referred to as CSF) from a sugar beet sugar factory using the Steffen method is used as a granulating agent, and in both cases, those with a water content of about 20 to 80% can be used. However, 20 to 50% is preferable. The components and viscosity of CSF as an additive are shown in Table 1 below. The above-mentioned CSF is obtained by separating the lime cake from the calcium carbonate-containing waste liquid, which is made up of lime cake (a mixture of calcium carbonate and organic substances, which are mainly the fibers used to make sugar) and waste liquid, and concentrating the remaining waste liquid. That's what you get.

Add 0.05Kg and mix using a ball mill. Calcium carbonate with carbon black mixed with 50% moisture
Add 0.7Kg of CSF and mix with a paddle mixer for 5~
Knead for 7 minutes. The kneaded CSF carbon black-containing calcium carbonate is fed into a rolling granulator. Calcium carbonate containing CSF carbon black, which was formed by rolling granulation using a rolling granulator for about 6 minutes, is dried for about 5 minutes using a rolling dryer.
Granular calcium carbonate fertilizer containing carbon black was obtained. This product was tested as a prototype. Test results Products obtained by conventional methods for prototypes obtained in Examples (indicated as "conventional products")
Figure 1 shows the test results regarding the change in the depth of remaining snow after the snow melting agent was applied. However, the conventional product was obtained by the following method and was also used in the tests. Observations were conducted in the Kitami region of Hokkaido from March 19, 1980 to April 9, 1981.
It took place during the day. In the above conventional product, calcium carbonate fertilizer containing carbon black was obtained by adding 0.05 kg of carbon black to 9.95 kg of calcium carbonate fertilizer and mixing in a ball mill. As the mixer, a common paddle mixer or the like may be used. From this snow melting effect, it can be seen that carbon black is mixed in the calcareous fertilizer more uniformly in the prototype product than in the conventional product. (Effects of the Invention) According to the present invention, carbon black is forcibly penetrated into the calcareous fertilizer by mixing with impact force, so even a very small amount of carbon black can be uniformly mixed compared to conventional methods, and it can be easily mixed with impact force. This has the effect of adhering to the calcareous fertilizer and maintaining its mixed state, and the resulting granular snow melting agent containing carbon black has the same strength as conventional granulated products and can be easily packed in bags. It is easy to handle during filling and spreading work, and after spreading, carbon black is dissolved and permeated into water via an additive containing hygroscopic organic matter, enters and descends into the snow, absorbs sunlight even into the snow, and absorbs its energy. This further enhanced the snow melting effect.
