The main content (measured in Na6P6O18) must meet the specified standards, and the content of impurities such as chlorides and heavy metals is strictly limited. During labeling, the full name of the product, specification model, manufacturer, production date, and implementation standards will be clearly marked on the packaging surface, and warning signs such as "moisture-proof" and "keep away from acid and alkali" will be clearly marked to facilitate user identification and supervision.
Preparation Method
Sodium Hexametaphosphate Industrial Grade SHMP is often prepared with sodium dihydrogen phosphate as the raw material. First, sodium dihydrogen phosphate is polymerized at high temperature (about 600-700℃), and the temperature, time and pressure and other conditions must be precisely controlled during the reaction. After the reaction is completed, the finished product is finally obtained through cooling, crushing and other processes. The whole process is like a craftsman carefully carving an object. Every link needs to be strictly controlled to ensure that the product quality meets the standard.
Chemical Reactions & Modifications
Sodium Hexametaphosphate Industrial Grade SHMP will undergo hydrolysis in aqueous solution. With different degrees of hydrolysis, phosphates with different polymerization degrees can be generated. When reacting with metal ions, it forms a stable complex through complexation, which is often used to remove calcium, magnesium and other ions in water to soften the water. By changing the reaction conditions or adding other reagents, it can be modified to adjust its complexing ability, hydrolysis rate and other properties to meet the special needs of different industries.

How is Sodium Hexametaphosphate Industrial Grade SHMP made?
This material is mostly made of sodium dihydrogen phosphate, which is melted and polymerized at high temperature. It is placed in a refractory ceramic kettle and heated with charcoal fire. The initial temperature rises to more than 300 degrees to gradually remove the moisture. When the material is molten, it is heated to about 650 degrees and calcined for two hours to make the molecular chains polymerize with each other. At this time, the material in the kettle flows like molten wax. It needs to be stirred from time to time with a long-handled iron spoon to prevent local scorching. When the color turns white, pour it into cold water and cool it suddenly. It condenses into a glass-like solid. After breaking it, grind it into powder to get Sodium Hexametaphosphate Industrial Grade SHMP. The method is similar to refining glass. If the fire is not enough, the chain is short, and if it is too much, the chain is broken. Only the one that gets the middle is the top grade.
What is the shape of Sodium Hexametaphosphate Industrial Grade SHMP?
It mostly appears as white powder or glass-like fragments, which are brittle and easy to grind. It looks slightly translucent and slightly shiny under light. It is smooth and smooth when twisted, and it is easy to absorb moisture. If placed in a wet place for ten days, it will clump and become sticky. It is soluble in water, and its aqueous solution is weakly alkaline, and it can combine with metal ions such as calcium and magnesium. It is stable at room temperature, but it is easy to decompose when it encounters strong acid, releasing the smell of phosphoric acid. It is safe with metal utensils, but aluminum and zinc are slightly corroded by it, so ceramics and plastics are suitable for storage. Its aqueous solution can lubricate the metal surface, so it is often used as a corrosion inhibitor in industry.
Where can Sodium Hexametaphosphate Industrial Grade SHMP be applied?
In industry, it is a good agent for water treatment. It can chelate calcium and magnesium ions in water to prevent scaling of pipes, and is especially suitable for boiler water treatment; it is used as a dispersant in papermaking to make pulp fibers evenly distributed and paper products smooth and tough. In the textile industry, it can be used as a bleaching and dyeing auxiliary to make the dye adhere evenly and the color bright; it is used as a flotation agent in mineral processing to help separate minerals from impurities. In the food industry, adding it to meat products can retain moisture and make the taste fresh and tender; adding a little to canned food can prevent fruits and vegetables from browning. It is used like weaving a net, which can pull things and adjust their order, so it is relied on by many industries.
How should Sodium Hexametaphosphate Industrial Grade SHMP be stored?
It should be packaged in a double-layer moisture-proof paper bag, wrapped with thick plastic film, and placed in a ceramic jar. The mouth of the jar should be sealed with a wooden cover, and the gaps should be coated with tung oil to prevent moisture. The storage place should be high, dry and ventilated, with wooden boards two feet above the ground, and quicklime bags should be placed next to absorb moisture. In the rainy season, it is necessary to take it out of the jar for inspection every three days, and replace the lime if it is slightly damp. When transporting, use a covered wooden box with hay inside to isolate it from shock. Cover it with oilcloth in rainy days to prevent it from getting wet. If it absorbs moisture and clumps, it can be placed on a ceramic plate and dried over a low fire. It can still be used after grinding, but the effectiveness is reduced by 10%, so the key to storage is to prevent moisture and humidity.
What is the difference between Sodium Hexametaphosphate Industrial Grade SHMP and Sodium Tripolyphosphate?
Although both are polyphosphates, they have different molecular chain lengths and different properties and uses. Sodium Hexametaphosphate Industrial Grade SHMP has a longer chain and a stronger ability to chelate metal ions; Sodium Tripolyphosphate has a shorter chain and a slightly stronger alkalinity. In terms of use, the former is more inclined to water treatment and papermaking, while the latter is mostly used in detergents and food. The manufacturing methods are also different. The former is made by high-temperature melt polymerization, while the latter is made by medium-temperature calcination. For example, two long and short ropes are both made of hemp, but the long one can be used to tie things, and the short one can be used to tie boats, each suitable for its own use.
