The future path for trisodium phosphate manufacturers

Trisodium phosphate is a phosphate with the chemical formula Na3PO4. Trisodium phosphate, commonly used in industry, is Na3PO4·12H2O containing twelve crystalline waters. Because the industries involved are: cleaning, printing and dyeing, descaling and purification. All walks of life combined with their own industry conditions, the use of trisodium phosphate will have different requirements. It can be roughly divided into: 1. the requirements for the main content; 2. the raw material requirements for the production of trisodium phosphate; 3. the requirements for the impurities contained; 4. the requirements for the appearance.

The production industry of trisodium phosphate can be roughly summarized as follows: the neutralization reaction of soda ash and phosphoric acid is used to generate a disodium hydrogen phosphate solution, and then the caustic soda is added to neutralize the disodium hydrogen phosphate, H3PO4+Na2CO3→Na2HPO4+H2O+CO2↑, Na2HPO4+NaOH→Na3PO4+H2O. It is then concentrated, dehydrated and crystallized to give trisodium phosphate. It is widely used mainly because of the phosphate it contains. Trisodium phosphate is hydrolyzed to obtain phosphate, and phosphate has a very good complexing and dispersing effect. For example, the principle of descaling of the boiler is to replace the calcium carbonate, calcium sulfate becomes loose calcium phosphate and falls off.

More common indicators: contains twelve crystalline water, the main content of more than 96%. Some customers will be more stringent: for example, in the printing and dyeing industry, the main content is required to be more than 98%, and then the content of impurities is required to be extremely low. In this case, the manufacturer has to control from the source of the product: usually to achieve such an effect, the raw materials used must be thermal phosphoric acid, soda ash and caustic soda can not be by-product products... There are even specific requirements for the process.

Some industries, such as boiler descaling, ordinary cleaning do not have too many requirements for trisodium phosphate. 98% or 96% choose directly depending on the company's considerations.

Today is the era of personalization. The same is true for chemical companies. Upstream enterprises should continue to explore and explore customer needs. Now the Liucheng brand is divided into 96% wet trisodium phosphate, 98% trisodium phosphate, and Chuandong trisodium phosphate. It is precisely to cater to customers, that is, to meet the needs of customers who require them, but also to save costs for ordinary users. As a versatile trisodium phosphate, his future path must be cascading, personalized...
