In 1893,Polyacrylamide was first created by Moureu through reaction of acryloyl chloride and ammonia under low temperature.
In 1950,American Cyanamid Company published the first patent of synthetic polyacrylamide.
In 1954,Polyacrylamide was put into industrial production in America. The first generation was sulfuric acid catalytic hydration technology. It was complex with high cost and low purity. The first type was nonionic polyacrylamide, then anionic polyacrylamide was developed.
In 1962,Shanghai Tianyuan Chemical Plant built the first polyacrylamide production unit to produce hydrosol products. It was not widely promoted and used due to the restrictions of viscosity, fluidity and solubility of the products.
In the early 1970s,Dow in America and Mitsui in Japan developed the second generation technology-binary or ternary raney copper catalyzing, almost no waste water, gas or residue; easy to achieve industrialization; containing small amount of additive reactants.
In 1980,Cationic monomer DAC was successfully developed in Japan. Cationic polyacrylamide was then put into production.
In 1990,Amphoteric polyacrylamide entered into market and was widely used.
In the early 21st century,Polyacrylamide market in China became more active. There were dozens of manufacturers but products were lack of variety and quality was not stable due to the restrictions of formulation, technology, development field and production costs.
In 2010,Shouxin officially began its way as a global polyacrylamide brand with stable quality, and its mission is to always develops and provide customers with the most stable & cost-effective polyacrylamide.
Shouxin History:
In 2007, Shouxin was established focusing on water treatment chemical materials.
In 2008, Transited to specialize in polyacrylamide. Set up professional R&D, quality control, sales and after-sales teams.
In 2009, Cooperated with China’s largest paper-making company Nine Dragons Paper.
In 2011, Optimized the whole system of raw material control, formula development, production process supervision and double inspection of incoming and outgoing goods with strictly selected partners.
In 2018, Bought the whole floor of Grade A office in Poly Group as the company new office and purchased more advanced testing instruments to improve the whole testing system.
In 2019, Number of listed company and top 500 company customers exceeded 100.
In 2021, The annual handling capacity exceeded 40,000 tons and won the Best Stable Quality Award by NFPIA.
