The following aspects need to be considered when choosing the right coal asphalt variety according to different uses:
1.Softening point: The softening point of coal pitch is one of the important factors that determine its use. The appropriate softening point needs to be selected according to the engineering requirements and local climatic conditions. Generally speaking, high-temperature coal bitumen is suitable for areas with low temperature in winter, medium temperature coal bitumen is suitable for spring and autumn seasons, and low-temperature coal bitumen is suitable for areas with higher temperature in summer.
2.Color: Different varieties of coal pitch also have different colors. Generally speaking, high-temperature coal asphalt is darker, medium-temperature coal asphalt is medium, and low-temperature coal asphalt is lighter. When choosing coal pitch, you can choose the right color according to the engineering requirements and local Xi. For example, in building waterproofing projects, low-temperature coal pitch with a light color can be selectedIn road paving, you can choose a darker color of high-temperature coal pitch.
3.Impurity content: Coal pitch contains a variety of chemicals, if the impurity content is too high, it will affect its use effect. Therefore, when choosing coal pitch, it is necessary to pay attention to the level of its impurity content, and try to choose varieties with low impurity content.
4.Waterproof performance: Some special coal pitch varieties have good waterproof performance, such as waterproof coal pitch. If you need to use coal pitch with waterproof properties, you can choose this variety.
5.Environmental protection requirements: Coal asphalt contains a variety of harmful gases and organic compounds, so it is necessary to pay attention to environmental protection issues. When choosing coal asphalt, you can choose varieties that have undergone environmentally friendly treatment, or take corresponding environmental protection measures in the process of use.
In summary, there are several factors to consider when choosing the right coal asphalt variety, including softening point, color, impurity content, waterproof performance, and environmental protection requirements. It is necessary to select the appropriate varieties according to the specific engineering requirements and the use environment.
