Potassium tripolyphosphate (K5P3O10) is a white, odorless, and water-soluble salt. It is commonly used as a sequestrant, emulsifier, and stabilizer in the food industry. It is also used in the detergent industry as a builder and water softener. Potassium tripolyphosphate can help prevent discoloration and improve the texture of processed meat products. It is generally recognized as safe (GRAS) by the US Food and Drug Administration (FDA) and can be used in various food applications, including canned meats, seafood, and poultry products.
Potassium tripolyphosphate (K5P3O10) is a white crystalline powder that is commonly used as a food additive and detergent builder. It is a type of tripolyphosphate, which is a polyphosphate compound that contains three phosphate groups.
In food, potassium tripolyphosphate is used as a sequestrant, which means it binds to metal ions and prevents them from reacting with other ingredients in the food. This helps to maintain the texture and flavor of the food. It is also used as a preservative, as it can inhibit the growth of bacteria and fungi.
In detergents, potassium tripolyphosphate is used as a builder, which means it helps to soften hard water and improve the effectiveness of the detergent. It can also help to prevent the redeposition of soil onto fabrics during the washing process.
However, the use of potassium tripolyphosphate has been controversial due to its potential environmental impact. When released into waterways, it can contribute to eutrophication, which is the excessive growth of algae and other aquatic plants that can deplete oxygen levels and harm aquatic life. As a result, some countries have restricted or banned the use of tripolyphosphates in detergents and other products.

The htd-2 thermal expansion stroke transmitter is equipped with various td-2 linear differential transformer sensors. The built-in excitation source and differential measurement circuit convert the amount of thermal expansion on both sides of the casing into 4~20ma current output. The difference between the two indicates the deformation of the casing. This deformation will cause a huge stress between the casing and the foundation, resulting in misalignment. If the casing sliding pin system is stuck, serious consequences will result.
