The role of medium-temperature asphalt in agriculture Zhao Na, a manufacturer of medium-temperature coal asphalt
1. Definition and types of medium-temperature asphalt.
Medium-temperature bitumen is an intermediate product in coal tar processing, which is mainly composed of polycyclic aromatic hydrocarbons and organic compounds. According to different processing methods and component ratios, medium-temperature asphalt can be further divided into medium-temperature coal asphalt and synthetic medium-temperature asphalt. Among them, medium-temperature coal asphalt is obtained by high-temperature distillation and decarburization of coal tar, while synthetic medium-temperature asphalt is prepared by chemical synthesis.
Second, the application principle of asphalt in agriculture.
In agriculture, the application of bitumen is mainly based on its physical and chemical properties. Asphalt has good adhesion and cohesiveness, which can effectively improve the structure and stability of the soil. In addition, asphalt can also be used as a moisturizer for soil and a carrier for chemical fertilizer, improving the utilization rate of chemical fertilizer and the growth efficiency of plants.
3. The effect of medium-temperature asphalt on soil moisture retention and chemical fertilizer stability.
Medium-temperature asphalt can effectively improve the moisture retention capacity of soil, and its polycyclic aromatic hydrocarbon components have good water molecule adsorption capacity, which can reduce the evaporation of soil moisture, so as to maintain soil moisture. In addition, medium-temperature asphalt can also be used as a carrier of chemical fertilizer, mixing chemical fertilizer with soil, so that chemical fertilizer is slowly released in the soil and improving fertilizer efficiency.
Fourth, enhance soil structure and persistence.
Medium-temperature asphalt can undergo physical and chemical reactions with minerals in the soil to form a stable organic-inorganic complex and improve the structure and persistence of the soil. In addition, medium-temperature bitumen can also reduce soil erosion and runoff by inhibiting the growth of fungi and bacteria in the soil.
5. Prevent soil erosion and erosion.
Medium temperature asphalt has good adhesion and cohesiveness, which can effectively prevent soil erosion and loss. The application of medium-temperature asphalt on the surface of agricultural land can form a protective film to inhibit water loss and wind erosion, and protect nutrients and water in the soil.
6. Improve plant growth and promote the reproductive process.
Medium-temperature asphalt contains a variety of organic compounds and trace elements, which can be used as nutrients for plants** and improve the growth and reproduction process of plants. In addition, medium-temperature asphalt can also promote the growth and reproduction of plants by adjusting soil pH and improving soil air permeability.
7. Increasing agricultural output value and improving economic efficiency.
Through the application of warm asphalt, the structure and properties of the soil can be improved, and the yield and quality of crops can be improved, thereby increasing the agricultural output value and improving the economic efficiency. In addition, medium-temperature asphalt can also be used as a disposal medium for agricultural wastes to realize the resource utilization of agricultural wastes.
8. Operation methods and precautions.
In agricultural applications, the operation of medium-temperature asphalt should follow safety codes and relevant regulations. Before use, you should understand the properties and mechanism of medium temperature asphalt, and master the correct use methods and precautions. At the same time, attention should be paid to the protection of the environment and the disposal of waste after use.
