제품 설명
Sodium Persulfate Na₂S₂O₈ 99% - Oxidizer for PCB, Polymerization Initiator & Soil Remediation
Sodium persulfate, with the chemical formula Na₂S₂O₈, is a highly soluble and widely used strong oxidizing agent in the persulfate series. This product is a high-purity (99%) white crystalline powder or granules. Its aqueous solution can be activated through various means such as heat, light, or transition metal ions to generate sulfate radicals (SO₄⁻*, E⁰=+2.6V) with an extremely high redox potential. This property makes it a core chemical raw material in fields like advanced electronics manufacturing, polymer synthesis, environmental remediation, and metal treatment.
Core Applications
Etchant and Cleaner for High-Precision Electronic Circuits
In the manufacturing of high-end printed circuit boards (PCBs), especially High-Density Interconnect (HDI) boards and IC substrates, sodium persulfate is a key component of precision copper micro-etchants and black oxide treatment solutions. It provides exceptionally uniform and stable etching rates, creating a controlled micro-roughness on copper surfaces to ensure extremely high bonding reliability during multilayer board lamination. It is also used for desmearing drilled holes and removing residual dry film, making it a critical chemical for enhancing the signal integrity and reliability of circuit boards.
Initiator for High-Performance Polymer Synthesis
As an efficient water-soluble free radical initiator, sodium persulfate plays a dominant role in emulsion polymerization, dispersion polymerization, and aqueous solution polymerization. It is particularly suitable for synthesizing high-weatherability acrylic resin emulsions, superabsorbent polymers (SAP), polytetrafluoroethylene (PTFE) dispersions, and anionic polyacrylamide (APAM) flocculants. Its sodium salt nature avoids potential issues with insoluble by-products that potassium salts might cause, making it especially suitable for polymerization systems requiring high purity and high conversion rates.
Ultimate Oxidant for Soil and Groundwater Remediation
In environmental engineering, sodium persulfate is one of the preferred reagents for In Situ Chemical Oxidation (ISCO) technology. By injecting it into contaminated subsurface zones combined with activation methods, the generated sulfate radicals can non-selectively oxidize and decompose recalcitrant organic pollutants such as BTEX (benzene, toluene, ethylbenzene, xylene), chlorinated ethenes (PCE/TCE), and polycyclic aromatic hydrocarbons (PAHs). This approach offers short remediation cycles and high efficiency, establishing it as a mainstream technical solution for petroleum-contaminated sites and groundwater remediation.
Metal Surface Treatment and Chemical Synthesis
Sodium persulfate is used for low-temperature chemical polishing of stainless steel and copper alloys, yielding bright and uniform surfaces. In the textile industry, it serves as a rapid wool bleaching agent and desizing agent. Furthermore, it is an important intermediate in producing other peroxides like sodium perborate and sodium percarbonate, and acts as a selective oxidizer in certain organic syntheses.
