Problems solved by technology

[0009] The object of the present invention is to provide a kind of composition that is used for the processing of selenium fertilizer (main raw material is the selenium ore powder that selenium-containing ore is processed), solves the processing and manufacturing of this kind of selenium fertilizer in the prior art due to the lack of good viscosity. The selenium ore powder is difficult to process or the pulverization is serious after processing due to the binding agent

Embodiment 1

[0041]

[0042] At room temperature, mix polyacrylamide, sodium chloride, and water at a ratio of 2:30:300 (by mass) and then fully stir; mix β-cyclodextrin and water at a ratio of 20:300 (by mass) ) and then fully stir evenly. The above two solutions are mixed and diluted with water to 1000 mass, and the binder and the selenium fertilizer raw material powder are mixed evenly in a ratio of 1:5. Smooth, no material compaction or machine blockage. The pulverization rate of the prepared granular selenium fertilizer is lower than 2% in the process of storage and transportation; in the process of field application, the selenium fertilizer can be completely disintegrated in 20 minutes after the selenium fertilizer meets water or watered, which is beneficial to the release of fertilizer effect.

Embodiment 2

[0044]

[0045] Under normal temperature conditions, mix polyacrylamide, sodium chloride, and water in a ratio of 3:40:300 (by mass) and then fully stir evenly; mix β-cyclodextrin and water at a ratio of 25:300 (by mass) ) and then fully stir evenly. The above two solutions are mixed and diluted with water to 1000 mass, and the binder and the selenium fertilizer raw material powder are mixed evenly in a ratio of 1:5. Smooth, no material compaction or machine blockage. The pulverization rate of the prepared granular selenium fertilizer is lower than 1.5% in the process of storage and transportation; in the process of field application, the selenium fertilizer can be disintegrated completely in about 30 minutes after being watered or watered, which is beneficial to the release of fertilizer effect.

Embodiment 3

[0047]

[0048] At room temperature, mix polyacrylamide, sodium chloride, and water at a ratio of 4:50:300 (by mass) and then fully stir; mix β-cyclodextrin and water at a ratio of 30:300 (by mass) ) and then fully stir evenly. The above two solutions are mixed and diluted with water to 1000 mass, and the binder and the selenium fertilizer raw material powder are mixed evenly in a ratio of 1:5. Smooth, no material compaction or machine blockage. The pulverization rate of the prepared granular selenium fertilizer is lower than 1% in the process of storage and transportation; in the process of field application, the selenium fertilizer can be disintegrated completely in about 45 minutes after being watered or watered, which is beneficial to the release of fertilizer effect.

Abstract

The invention discloses a composite used for selenium fertilizer processing and a preparation method and application thereof. The composite comprises the following components by weight percent: 0.1%-0.5% of polyacrylamide, 0.5%-5% of beta-cyclodextrin, 1%-10% of sodium chloride and the balance of water. After the composite used for selenium fertilizer processing is mixed evenly with selenium fertilizer material powder in a ratio of 1:5 and the mixture is granulated, selenium fertilizer particles are formed. The composite can be used as the binder of the selenium fertilizer particles; and the selenium fertilizer particles processed by using the composite have good particle stability and stable particle size.

Description

technical field [0001] The invention relates to a binder, in particular to a binder containing selenium mineral powder and the application of the binder, and belongs to the technical field of organic polymer compound application and fertilizer production. technical background [0002] Selenium is a rare dispersed element, that is, it does not form an independent mineral in nature but is dispersed in other elements in the state of impurities. The crustal abundance of selenium is very low, only 0.08×10-4%. At the same time, the ore of selenium as a simple substance is extremely rare. At present, the only area in the world where selenium is independently ore-formed is located in Enshi, Hubei, my country. [0003] Selenium is an essential trace element for humans and animals. It has biological properties such as scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, enhancing immunity, and antagonizing heavy metals. The daily selenium intake recommended by the Chines...
