As an admixture of concrete, water reducing agent plays an important role in improving the performance of concrete. Water reducing agent is an admixture that can significantly reduce mixing water consumption while keeping the working degree of cement paste, mortar and concrete unchanged. Impermeability or reduced cement dosage. This example provides a method of using waste PET plastic to produce water reducing agent, can recycle waste PET plastic, reduce pollution, reduce the production cost of water reducing agent.
Pet-based polyester material is not degradable, and it has the advantage of being recyclable, eliminating the need to reuse terephthalic acid and ethylene glycol for polymerization. However, the processing and recycling technology of PET materials still need to be further developed and perfected. Polyester is the main material for spunbonded non-woven fabrics, which can be used at 260°C for a long time. The spunbonded and hot-rolled non-woven fabrics made from waste PET can reduce the production cost of enterprises. By making full use of the characteristics of recycled polyester materials, The strength properties of polyester spunbonded and hot-rolled non-woven fabrics are further improved through process control.
