At present, various general cement pipes on the market can no longer be satisfied with the environmental protection requirements of current construction units. With the improvement of construction safety guidelines and the increase of the attention of relevant departments to construction sites, manufacturers now The requirements have also been significantly improved. Under the premise of convenience for our urban drainage water, we also have certain requirements regarding the environmental protection of the use of cement pipes. In recent years, the importance of environmental protection has been continuously increased, and the policies of various industries and industries have gradually responded to the path of green environmental protection. So how to make cement pipe manufacturers go green?
1. How to make cement pipe manufacturers go green?
The development of environmental protection industry is a common topic of humankind. For the industry of cement pipes, the development of environmentally friendly production processes must be considered from two aspects: one is the raw materials of cement pipes, and the other is the performance of cement pipes.
1. Application of raw materials in cement pipes
Considering the use of raw material cement for large-scale cement pipes, green concrete cement pipes should be selected as much as possible. The so-called selection of green concrete cement pipes is to use less or no cement. The production of cement requires large energy consumers such as electricity and coal. During the production process, dust particles are polluted. According to statistical calculations, the production of 1 ton of cement will burn coal. It emits about 1 ton of CO2, together with dust and other harmful gases. Add more industrial waste-based admixtures to save resources, power, and protect the environment. The waste can be reused and produced in a sustainable manner.
2. Application performance of cement pipe
Considering the performance of large-scale cement pipes, in recent years, due to the improvement of people's daily quality, the addition of proteins in sewage formed by daily garbage, the widespread use of household chemical synthetic detergents such as laundry, the complexity of industrial wastewater, and soil media in some areas The corrosion itself, the corrosion resistance of general cement pipelines, is already a serious problem.
The development and production of corrosion-resistant large-scale cement pipelines has been put on the factory production agenda. A lot of research work done by relevant departments has successfully developed large corrosion-resistant cement drainage pipes. It uses slag, fly ash, admixtures as cementing materials to replace the cement in general concrete, and its hydration products are mainly zeolite hydrated aluminosilicates, making the corrosion-resistant concrete cement pipe at a pH of 2-13 The environment has better corrosion resistance than ordinary concrete cement pipes. The erosion effect of daily sewage, industrial wastewater and soil medium on concrete cement pipes is well solved, and the service life of cement pipes is greatly improved.
