Coal tar asphalt is one of the main products of coal tar processing.
I. Introduction. Coal tar asphalt is one of the main products of coal tar processing, which is widely used in road construction, waterproof materials, anti-corrosion coatings and other fields. In order to ensure the quality and effectiveness of coal tar asphalt, it is essential to develop and enforce appropriate standards.
The purpose of this article is to elaborate the relevant content of the implementation standard of coal coke asphalt and provide reference for production, use and management.
2. Overview of the implementation standards for coal coke asphalt.
The implementation standards for coal coke asphalt mainly include the following aspects:
1.Quality standards: stipulate the physical and chemical performance indicators of coal coke asphalt, such as penetration, softening point, ductility, ash content, etc., to ensure that the product quality meets the requirements of use.
2.Environmental protection standards: Limit the emission of pollutants in the production process of coal coke asphalt to protect the environment and human health.
3.Safety standards: stipulate the safety requirements during the production, storage, transportation and use of coal and coke asphalt to prevent accidents.
3. Quality standards for coal coke asphalt.
1.Penetration: Penetration is an important indicator to measure the viscosity of coal coke asphalt, and the penetration requirements of coal coke asphalt for different purposes are different, and it needs to be tested and evaluated in accordance with relevant standards.
2.Softening point: The softening point is the temperature at which the coke asphalt begins to soften under certain conditions, reflecting the thermal stability of the asphalt, and the requirements for the softening point of the coal coke asphalt are also different for different purposes.
3.Ductility: Ductility is the deformation capacity of coal coke asphalt during the stretching process, reflecting the flexibility and crack resistance of the asphalt. The ductility requirements of coal coke bitumen depend on the specific use.
4.Ash: Ash is the content of inorganic impurities in coal coke asphalt, and too high ash content will affect the performance of asphalt. Therefore, the ash content of coal coke asphalt should be controlled within a certain range, generally not exceeding 01%。
Fourth, coal coke asphalt environmental protection standards.
1.Exhaust gas emissions: The exhaust gas generated in the production process of coal coke asphalt should meet the emission standards stipulated by the national and local environmental protection departments to reduce air pollution.
2.Wastewater discharge: The wastewater generated in the production process should be treated to meet the discharge standards stipulated by the national and local environmental protection departments to avoid pollution of water sources.
3.Solid waste treatment: The solid waste generated in the production process should be properly disposed of in accordance with the requirements of the national and local environmental protection departments to prevent pollution to the environment.
5. Safety standards for coal and coke asphalt.
1.Production safety: In the production process of coal and coke asphalt, safety production regulations should be strictly adhered to to ensure equipment safety and operation specifications, and prevent fires, accidents such as fire and safety.
2.Storage safety: Coal and coke asphalt should be stored in a special warehouse that meets safety requirements to avoid unfavorable factors such as direct sunlight and high temperature to ensure product quality and safety.
3.Transportation safety: Coal coke asphalt should take measures such as leakage prevention and fire prevention during transportation to ensure transportation safety.
4.Safety of use: When using coal tar asphalt, the relevant safety operation procedures should be observed, and protective equipment should be worn to ensure the safety of operators.
VI. Conclusions. The implementation standard of coal coke asphalt is an important guarantee to ensure the quality, environmental protection and safety of coal coke asphalt. This article introduces in detail the relevant content of the implementation standards of coal coke asphalt, including quality standards, environmental protection standards and safety standards.
It is hoped that this paper can provide a reference for the production, use and management of coal coke asphalt and promote the healthy development of coal coke asphalt industry. Reading cured my mental exhaustion
