| Basic performance: |
| Sodium pyromonate is an inorganic salt compound of antimony with low toxicity. It is made from antimony products such as antimony oxide through alkali and production. Appearance is white powder, there are two kinds of granular crystal and equiaxed crystal. The melting point is 1200 ° C and the boiling point is 1400 ° C. Soluble in tartaric acid, sodium sulfide solution, concentrated, slightly soluble in methanol, ammonium salt, insoluble in acetic acid, dilute alkali and dilute inorganic acids, insoluble in cold water. Good chemical stability. |
| Application: |
| Pyropyrate is mainly used as a clarifier and defoamer for photovoltaic solar glass, black and white, and color display picture tube glass. Clarifying defoamer for high-grade glass such as glass fiber, gem glass, high-grade glass tableware, and flame retardants that are more widely used in engineering thermoplastics and rubber, such as flame-retardant electronic equipment housings, flame-retardant compartments, and flame-resistant wires. It is also used as a flame retardant for textiles, plastics, and building materials. It is widely used internationally as a clarifier to replace antimony oxide. |
| Rhenium is widely used internationally as a flame retardant to replace antimony oxide. It has been confirmed by scientific experiments and production that it has more excellent technical performance. Used in all polymers, has better flame retardancy, used in saturated polyester and engineering thermoplastics has lower light resistance and lower color strength, it has the characteristics of low reactivity, which is An advantage in sensitive polymers (such as PET), and commonly used antimony oxide flame retardants are prone to cause depolymerization during operation. |
