Embodiment 1

[0041]

[0042] At room temperature, mix polyacrylamide, sodium chloride, and water according to the ratio of 2:30:300 (by mass) and stir well; combine β-cyclodextrin and water according to 20:300 (by mass) ) After mixing, stir well. Mix the above two solutions and dilute with water to 1000 mass, mix the binder and selenium fertilizer raw material powder uniformly in a ratio of 1:5, the particle size is uniform and stable during the granulation process, the obtained particles are dense and firm, and the granulation process Smooth, no material compaction or machine blockage. The pulverization rate of the prepared granular selenium fertilizer is lower than 2% during storage and transportation; in the field application process, the granules of the selenium fertilizer can be completely disintegrated after being exposed to water or watering, which is beneficial to the release of fertilizer efficiency.

Embodiment 2

[0044]

[0045] Under normal temperature conditions, mix polyacrylamide, sodium chloride, and water according to the ratio of 3:40:300 (by mass) and then fully stir it evenly; combine β-cyclodextrin and water according to 25:300 (by mass) ) After mixing, stir well. Mix the above two solutions and dilute with water to 1000 mass, mix the binder and selenium fertilizer raw material powder uniformly in a ratio of 1:5, the particle size is uniform and stable during the granulation process, the obtained particles are dense and firm, and the granulation process Smooth, no material compaction or machine blockage. The pulverization rate of the prepared granular selenium fertilizer is lower than 1.5% during storage and transportation; in the field application process, the granules of the selenium fertilizer can be completely disintegrated after being exposed to water or watering, which is beneficial to the release of fertilizer efficiency.

Embodiment 3

[0047]

[0048] At room temperature, mix polyacrylamide, sodium chloride, and water according to the ratio of 4:50:300 (by mass) and then fully stir it; combine β-cyclodextrin and water according to 30:300 (by mass) ) After mixing, stir well. Mix the above two solutions and dilute with water to 1000 mass, mix the binder and selenium fertilizer raw material powder uniformly in a ratio of 1:5, the particle size is uniform and stable during the granulation process, the obtained particles are dense and firm, and the granulation process Smooth, no material compaction or machine blockage. The pulverization rate of the prepared granular selenium fertilizer is lower than 1% during storage and transportation; in the field application process, the granules of the selenium fertilizer can be completely disintegrated after being exposed to water or watering, which is beneficial to the release of fertilizer efficiency.

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 and dispersed element, that is, it does not form independent minerals in nature but is dispersed in minerals of other elements as impurities. The crustal abundance of selenium is very low, only 0.08×10-4%. At the same time, selenium exists as a simple substance and the ore is extremely rare. At present, the only independent selenium mineralization area in the world is located in Enshi, Hubei, my country. [0003] Selenium is an essential trace element for humans and animals. It has the biological properties of scavenging free radicals, anti-oxidation, anti-aging, anti-cancer, strengthening immunity, and antagonizing heavy metals. The Chinese Nutrition Society recommends a daily inta...
