The role of coal pitch in waterproofing materials
I. Introduction. With the increasing attention to the waterproof performance of buildings, waterproof materials are more and more widely used in construction projects. As an important waterproof material, coal pitch has an irreplaceable role in building waterproofing engineering due to its unique chemical properties and physical properties. This article will detail the role of coal pitch in waterproofing materials.
Second, the characteristics of coal pitch.
Coal pitch is a by-product of coal tar processing, which is mainly composed of polycyclic aromatic hydrocarbons and fused aromatic hydrocarbons, and has high chemical and thermal stability. In addition, coal pitch also has good plasticity and adhesion, making it play an important role in waterproofing materials.
3. The role of coal pitch in waterproof materials.
1.Improve waterproofing performance: Polycyclic aromatic hydrocarbons and fused aromatic hydrocarbons in coal pitch can form a network structure with polymer compounds in asphalt, increasing the viscosity and strength of asphalt, thereby improving waterproof performance.
2.Enhanced durability: Coal pitch has high chemical stability and can resist the erosion of the natural environment and chemicals, thus ensuring the durability of the waterproofing material.
3.Improve plasticity: The fused cyclic aromatic hydrocarbons in coal pitch have good plasticity, which can improve the plasticity and adhesion of asphalt, make it easier for asphalt to bond with other materials, and improve the construction quality of waterproof materials.
4.Cost reduction: Coal pitch as a by-product of coal tar is relatively low, so using coal pitch as a waterproofing material can reduce construction costs.
Fourth, application examples.
A large commercial center in a city uses coal asphalt as the main waterproof material for roof waterproofing transformation. During the construction process, the construction personnel mixed coal pitch with other materials to create a high-quality waterproof layer. After several years of use, the roof of the commercial center remains dry and no leakage has been found, proving the important role of coal pitch in waterproofing materials.
V. Conclusions. This article details the role of coal pitch in waterproofing materials. Coal pitch has high chemical and thermal stability, good plasticity and adhesion, which can improve waterproofing performance, enhance durability, improve plasticity and reduce costs. In practical application, coal pitch has become an important waterproof material, widely used in buildings, roads, bridges and other fields. With the continuous progress of science and technology and the continuous development of application technology, the application of coal pitch in waterproof materials will be more extensive.
