Sodium hexametaphosphate is a salt of composition Na6[(PO3)6].Sodium hexametaphosphate of commerce is typically a mixture of metaphosphates (empirical formula: NaPO3), of which the hexamer is one, and is usually the compound referred to by this name. Such a mixture is more correctly termed sodium polymetaphosphate. They are white solids that dissolve in Water Treatment.
SHMP is used as a sequestrant and has applications within a wide variety of industries, including as a food additive in which it is used under the E number E452i. Pvc Resin Shmp Food Grade is sometimes added to Shmp 68 to raise the pH to 8.0–8.6, which produces a number of SHMP products used for water softening and detergents.
A significant use for Shmp Food Additive is as a deflocculant in the production of clay-based Melamine Powder ceramic particles.It is also used as a dispersing agent to break down clay and other soil types for soil texture assessment.

Shanghai Gosstone Marine Fittings Co., Ltd. successfully passed the MAN Diesel & Turbo four-stroke medium-speed series diesel engine (purchasing supply) supply valve (purchasing supply) and seat Production supplier certification, becoming the first company in the world to obtain this qualification. He Caitian, general manager of Gossip, said that this certification once again proves that domestic suppliers have the ability to achieve world-class standards in key equipment.
    Key equipment breakthrough
    Exhaust valves have long been one of the most important components of high performance diesel engines. Its quality will directly affect the overall performance and service life of the diesel engine. Whether the exhaust valve is durable or not depends on the hardness, high temperature resistance and corrosion resistance of the alloy layer on the sealing surface. In order to improve the quality of the exhaust valve, the foreign mainframe (purchasing supply) manufacturers have entered the research field since the 1960s, and have tried a variety of different surfacing processes, and finally developed a sealing surface hardness of HRC55 ( Rockwell hardness) exhaust valve finished. In contrast, the domestic start is relatively late, the technical accumulation is relatively weak, the hardness of the relevant finished products is always above and below the HRC45, and it is easy to crack when it is raised upwards. Chinese mainframe manufacturers have been forced to import exhaust valves and valve seats, which has restricted the technological progress and localization of China's "ship heart".
    In 2003, Gossip aimed at the above market opportunities and tried to change the properties of the sealing surface material through process innovation to greatly enhance its physical and chemical properties. The company selected a variety of surfacing processes, extensively tried various brands and models of welding (product library purchase supply) materials, after hundreds of tests and technical research, after three years, finally independently developed "valve valve face vacuum melting Welding high temperature rolling hardening technology". The technology greatly reduces the defects such as pores, slag inclusions and looseness which may occur when the welding material is fused with the base material, and refines and improves the metallographic structure of the alloy layer, greatly improves its toughness and improves the hardness of the weld overlay layer. Go to HRC55 or above. In addition, Gaston has independently developed and innovated the normal temperature rolling strengthening technology of the valve neck R, so that the surface roughness of the valve R reaches the mirror surface, further improving the fatigue strength of the valve and reducing carbon deposition. In 2009, the two technologies were awarded the invention and utility model patent certificates of the State Intellectual Property Office of the People's Republic of China. Due to the above technological advances, in 2010, Gasstone became the first company in China to pass the Mann company's two-stroke low-speed diesel engine exhaust valve qualified production supplier certification. Domestic host manufacturers have finally got rid of the dependence on foreign imported exhaust valves and valve seats.
    The potential of technological innovation
    Benefiting from technological innovation, Gossstone has developed rapidly in recent years. He Caitian said that due to being among the world's top suppliers of high-end diesel engines, the company is currently facing a situation of “supply in short supplyâ€. It has invested 100 million yuan in a new factory in Shanghai Pudong Lingang Heavy Equipment Park. The project has been completed and accepted. In the current situation of the new shipbuilding market being devastated by the “waistâ€, the experience of the company has fully demonstrated the huge potential of innovative enterprises and the international market share that domestic suppliers can transfer through technological and technological changes.
    Through independent technological innovation, Gossip produces products of the same quality or even better as those of developed industrial countries, breaking the situation that high-end products in this field are completely dependent on imports, and greatly reducing the cost of using domestic major OEMs and ship users. When the ship market is in a downturn, this will undoubtedly bring significant benefits to major users.
    The high-end supporting localization will not only greatly improve the profitability of the enterprise, but also promote the localization and technological progress of the “ship heartâ€, all of which depend on technology accumulation. If the domestic mature and developed supplier chain is formed, the host research and development can get rid of the dependence on foreign support. The maturity of the supporting market is highly correlated with the company's concentration and durability. In fact, Gothic's excitement lies in its keen capture of the direction of market demand and its ability to innovate in craftsmanship. He Caitian has made a number of different opinions on Mann's technical documents and successfully persuaded the latter to recognize his new craft. In order to further improve the safety and reliability of the four-stroke diesel engine valve and extend the service life of the valve, Mann Company has entrusted Gosstone to develop and test the new-generation four-stroke DuraSpindle valve. Mann has completed the physical and chemical testing of the prototype products. The results were better than expected and the durability test began. The above two major specialties are inseparable from the improvement of the process of dripping water and stone through the years. In a word, to become a global leader in the development and manufacture of gas valves, state-owned enterprises must accumulate a rich "artisan spirit."
