Domestic polycarboxylate polyether monomer market status

In the 21st century, the construction industry has developed rapidly, and research on concrete preparation and construction technology has reached a new height at home and abroad. The performance of concrete mixes has changed from early dry hardness to today's easyness and high fluidity. The strength of concrete also ranges from medium to low strength to today's high strength and ultra high strength. The comprehensive performance of concrete changes from ordinary performance to multi-functionality, such as ultra-high strength concrete, aerated concrete, heat-resistant concrete and non-dispersible underwater. Various applications such as concrete are becoming more and more widely used.

The large-span, large-volume, high-rise and mechanized construction of concrete structures determine the development of concrete with high workability, high mechanical properties and high durability. However, the improvement of concrete performance and technological progress are inseparable from the renewal of raw material varieties and the advancement of raw material technology. With the steady development of China's concrete water reducing agent manufacturing industry, especially the introduction of relevant national policies, China's concrete water reducing agent system.The manufacturing industry has ushered in a good development opportunity.

Polycarboxylate superplasticizer can produce ideal water reduction and reinforcement effect when the dosage is low, less influence on concrete setting time, good slump retention, and adaptability to cement/mixture It is relatively good, has little influence on the shrinkage of concrete, does not use formaldehyde in the production process, does not discharge waste liquid, and has low salicylate and low chloride ion content, and becomes a naphthalene, melamine, aliphatic and amino group. A new generation of water reducing agent after sulfonate-based water reducing agent. In recent years, in order to improve the urban environment, reduce urban noise and dust pollution, and strengthen urban construction management, all provinces and cities require that all concrete be made of commercial concrete, and on-site mixing is prohibited. This requirement indicates that commercial concrete must be produced centrally at the mixing station. In order to ensure the smooth construction of commercial concrete after long-distance transportation, water-reducing agents must be added during concrete production or mixing. The characteristics of polycarboxylate superplasticizer are also very obvious and have strong advantages. Polycarboxylate superplasticizer can form a series of products, which distinguishes polycarboxylate superplasticizer and traditional The key to high performance water reducers.
