High Performance Naphthalene Superplasticizer For Concrete CAS No. 9008-63-3 Naphthalene superplasticizer Chemical name: �² Sodium naphthyl sulfonate formaldehyde condensate. Molecular formula: (c10h6ch2naso3) n, n is mainly 9-12. Joyreach Fdn Powder Naphthalene Water Reducing Admixture Superplasticizer for Concrete Package 25kg/50kg Naphthalene superplasticizer has good adaptability to various cements and improves the operability of concrete.FDN has the advantage of high water reducing ratio, non-delayed coagulation, non-air entraining and strong adaptability. It can improve the workability of concrete to a large extent so as to reduce the water consumption for blending. Meanwhile, it can improve the strength of concrete. It is widely used in concrete engineering: highway, railway, bridge, tunnel, power station, dam, high-rise building and other projects.It has good dispersion, water reduction and early-strength effect.Adding naphthalene series superplasticizer into ordinary concrete can improve the physical and chemical properties of concrete, improve the concrete strength, construction speed, project quality, technology and working conditions. 1. early strength admixture - improve construction progress; 2. retarding admixture - prevent cracking of large infrastructure such as airports and bridges; 3. pumping type admixture - transported by pump, such as high-rise buildings; 4. antifreeze admixture - used for winter construction. FDN-A High concentration product with sodium sulfate content no more than 5 percent. FDN-AI Middle concentration product with sodium sulfate content no more than 10 percent. FDN-AII Low concentration product with sodium sulfate content no more than 18 percent. FDN-23 sodium sulfate content no more than 23 percent,cheapest type to save cost. Usage method: --Powder 0.5%-1.0%, recommended dosage 0.75%; --Liquid is 1.0%-2.0%, and the recommended mixing amount is 1.5%. The mixing amount can be appropriately increased according to the grade of concrete. --Each batch of goods must be tested to meet the engineering requirements before use. 1. As the requirement of engineer,the dosage can be adjusted after testing. 2. It can be put into blender with mixing water,making mixing before concrete pouring,the plasticizing effect could be better.

PWM speed regulation Xiongcai Technology is one of the few manufacturers providing clients with solutions and finished products. We engineer, analyze, test and supply finished products. You will see most of manufacturers provide OEM service only, they don�¢??t care about the handling, performance, even appearance, but we care all these. We take them seriously just as we value our own eyes. Five years ago, Unicent Automotive Tech, a company focused in automotive thermal management, contacted us and inquired about motor controller for automotive water pump. The client was really picky and particular, their engineer team set a standard on protection measure beyond the industry. They said they had met several suppliers, some items of the standards were unacceptable, because if all items met this extremely high standard, the cost would exceed budget. Our R&D team evaluated the list and decided to challenge the advancement works. The R&D team designed a combination of software and hardware meticulously called XCC107. In the next several months, they repeated the designing, testing, modifying, trying to have all parameters meet customer�¢??s requirements. Four months later, they achieved it. After one year test and verification in vehicle testing, Xiongcai XCC107 motor controller for water pump was approved. The product has been introducing to Unicent for 4 years till now. Xiongcai XCC107 motor controller for water pump provides protection measures including under voltage, over voltage, over current, low temperature, over temperature, plugging, reverse connection, short circuit, this means the motor controller may stop working due to some reason but never be damaged. We are one of the few engineering companies providing a full service from design to supply. Xiongcai is serving top clients in auto industries, such as NISSAN, XPeng, Jingyi Group, Risun, FAW Group, FAWDE, Feilong Auto (FLACC), Keshen, Unicent and more. Contact us for detail.
