Comparative analysis of polycarboxylate superplasticizer market at home and abroad

Views: 1     Author: Site Editor     Publish Time: 2020-10-21      Origin: Site


       The fundamental gap between China and foreign countries is that the parent performance of polycarboxylate superplasticizer developed in China is single, and there are not many varieties, which can not meet the requirements of different performance concrete in different fields, which restricts the wide application and development of polycarboxylate superplasticizer in China. Polycarboxylate superplasticizer masterbatch in foreign countries mainly has high water reducing type, high slump retention type and high early strength type with a concentration of more than 40%. In addition to meeting the requirements for different properties such as early strength, retarding setting and pumping, it also has higher advantages in plasticization, air entrainment, bubble structure, retarding effect, slump retention and viscosity. Since 2006, the number of enterprises producing polycarboxylate admixture has grown from about 10 to more than 150 at present, and the market scale is expanding continuously. However, most domestic enterprises are relatively backward in technology, lack of effective adjustment means for domestic complex raw materials, and the performance of mother liquor is poor. In addition to the extensive participation of naphthalene series manufacturers in the past, there are also some entrants who are optimistic about the market prospect of polycarboxylic acid products from the chemical or iron and steel industry. There are about 20 comprehensive enterprises with relatively comprehensive technical means. There is a certain gap between the domestic product quality and the imported product.

       In terms of the usage of polycarboxylate superplasticizer, China has become the country with the largest amount of polycarboxylate superplasticizer. However, there is still a certain gap between China and Japan and Europe in terms of application popularity. The proportion of polycarboxylate superplasticizer is the highest in Japan, which accounts for about 90% of the total amount of water reducer. The amount of polycarboxylate superplasticizer in Europe accounts for about 50% of the total amount of superplasticizer, which is not widely used in ready mixed concrete, but has been widely used in prefabricated components. Since 2006, driven by high-speed railway, China's polycarboxylate superplasticizer has achieved explosive growth. At present, polycarboxylate superplasticizer only accounts for about 37% of the water reducer market share, compared with the foreign market share, there is still a lot of room for development. According to the development experience of concrete superplasticizer industry in foreign countries, carboxylic acid water reducer will increase rapidly at a speed higher than the average level of water reducer industry with its superior product performance, and the proportion of carboxylic acid water reducer in the total amount of water reducer will continue to increase.

        At present, the development of polycarboxylate superplasticizer has entered a critical stage. Before that, polycarboxylate superplasticizer was mainly used in the national key and major engineering construction fields. The representative projects include high-speed railway engineering, sea crossing bridge, nuclear power engineering, rail transit (subway) engineering, landmark local construction engineering and other important projects with durability requirements. Polycarboxylate superplasticizer is used in these projects, and the dosage tends to be saturated. Therefore, in order to further expand the amount of polycarboxylate superplasticizer, it is necessary to speed up the application of polycarboxylate superplasticizer in ready mixed concrete. If the application of polycarboxylate superplasticizer in common ready mixed concrete engineering can be solved, another opportunity for rapid development will be obtained; on the contrary, if the problems of sensitivity and compatibility with raw materials of polycarboxylate superplasticizer in common ready mixed concrete can not be solved, its application may enter a relatively stable development period.

           Compared with developed countries, the development degree of ready mixed concrete in China is still very low; with the policy of "forbidding and supporting ready mixing" continuously promoted and tightened, and the direction of "Twelfth Five Year Plan" is determined, ready mixed concrete will get sustained and rapid development in the next five years, which will bring great development opportunities to water reducer.

        Rigorous and scientific research methods can ensure the accuracy and quality of research reports. The main research methods used in the 2013-2017 China polycarboxylate superplasticizer market and investment analysis report are as follows: 1) general survey: We conducted face-to-face or telephone interviews with nearly 100 practitioners in the polycarboxylate superplasticizer industry to obtain the best first-hand data. 2) Tracking research: in order to ensure the real-time grasp of the development trend of polycarboxylate superplasticizer industry, we have established a tracking research mechanism in the polycarboxylate superplasticizer industry, and obtain the development trend of polycarboxylate superplasticizer industry through visits every month. 3) Government agency data: we have inquired the industrial and commercial archives of key enterprises in the polycarboxylate superplasticizer industry, the archives of the Statistics Bureau, and the import and export data of the customs, etc., to obtain more authoritative information. 4) SOWT analysis: using SWOT analysis, Porter's five forces analysis and other methods, we analyzed the competitive advantages and disadvantages, potential threats and development opportunities of polycarboxylate superplasticizer industry and enterprises. 5) Scientific prediction: we use regression analysis, time series analysis, factor analysis, combination analysis and other methods to predict the development trend of polycarboxylate superplasticizer.
