Shanghai high speed railway chemical building materials Co., Ltd. is a company mainly engaged in the R & D, production and sales of concrete additives; As a high-tech enterprise providing relevant technical consultation and after-sales service, it has a 10000 square meter production base in Shanghai Jinshan Chemical Industry Zone and a product R & D center in Fudan University. In 2006, the company cooperated with Fudan University to successfully develop polycarboxylate superplasticizer series products. At present, polycarboxylate high-performance superplasticizers include solid powder products and liquid products with solid content of 20% and 40%, with a production capacity of 30000 tons / year, which can meet the needs of various construction projects, with good product stability, and various quality indexes reaching the leading level of similar products in the world. With advanced equipment, scientific management, excellent R & D team and excellent reputation, the business of Shanghai high speed railway chemical building materials company will quickly spread all over the country and become a dazzling new star in the chemical building materials market. The company has passed the ISO9000 quality system certification and ISO14000 environmental system certification, established a perfect quality management system and environmental management system, and ensured the high-quality stability of product quality and cleaner production. We will also follow the purpose of win-win with customers and provide customers with high-quality after-sales service. 2、 The development of polycarboxylate superplasticizer is divided into three stages: the first generation of superplasticizer represented by wood calcium, the second generation of superplasticizer represented by naphthalene series and the third generation of high-performance superplasticizer represented by polycarboxylate. Compared with the second generation superplasticizers such as naphthalene series, the performance and quality of the third generation polycarboxylic acid superplasticizers have been qualitatively improved, which can basically meet the performance requirements of high-performance concrete for superplasticizers. These products basically have the technical performance advantages and economic conditions to replace naphthalene superplasticizers. The advantages of polycarboxylate superplasticizer are as follows: 1. Early strength and high strength: the early strength is increased by more than 70% and the 28 day strength is increased by more than 40%, which is especially suitable for high content fly ash concrete; 2. Low slump loss: according to the standard of pumping agent, the slump loss in 1 hour is less than 30mm; 3. High durability: This product can effectively reduce the water binder ratio of concrete, improve durability, and reduce shrinkage and creep deformation; 4. High water reduction rate: when the slump is about 80mm, the water reduction rate is more than 25%; When the slump is about 200mm, the water reduction rate is more than 33%; 5. Small dosage and low cost: usually the dosage is 0.5 ~ 1.2% of cementitious material; 6. Green environmental protection product: This product does not produce pollution to the natural environment in the production process, and conforms to the international standard of ISO 14000 environmental protection management. 3、 open
