Product Description

Product Description

 

Potassium permonosulfate complex salt, with the molecular formula of 2KHSO5·KHSO4·K2SO4, is abbreviated as PMS in English. It is a stable, convenient, and widely used excellent acidic oxidant. Its application areas include oral cleaning, swimming pool and hot spring water disinfection, circuit board etching agent, pulp bleaching, wool fabric shrinkage treatment, precious metal refining, etc. It can also be used as an oxidant for sulfur-containing substances such as hydrogen sulfide in wastewater treatment, a low-temperature oxygen bleach in detergents, and an oxygen supply agent in aquaculture.

 

Uses

 

Application field of potassium permonosulfate complex salt

Potassium permonosulfate complex salt with the molecular formula 2KHSO5· KHSO4· K₂SO4, abbreviated as PMS, PMPS or KMPS. It is a stable, convenient, excellent acid oxidant with a wide range of uses, its application fields involve oral cleaning, swimming pool and hot spring water disinfection, circuit board etching, pulp bleaching, wool fabric shrinkage treatment, precious metal refining, etc.; Potassium permonosulfate complex salt is an important additive in organic synthesis, which can epoxidize the double bonds in organic molecules, and is a free radical initiator for many polymerization reactions. In addition, potassium permonosulfate composite salt can be used as an oxidizing agent for sulfur-containing substances such as sulfur hydride in wastewater treatment, a low-temperature oxygen-based bleach in detergents, and an oxygen supply agent in aquaculture.

Water treatment

Potassium permonosulfate complex salt (hereinafter referred to as PMS), is a powerful non-chlorine oxidant that can degrade and remove various pollutants. Excellent environmental features, ease of use and transport, safe handling and good stability make PMS an attractive choice for water treatment applications. Compounds that can be oxidized/neutralized by PMS are: ammonia and amine compounds; Nitrite; Aldehydes; organic amines; organic sulfides; Pesticide; quinolines; cyanide and thiocyanate; Hydrogen sulfide and organic sulfides, etc.

Paper

PMS can be used as a processing aid for repulping or secondary fiber batching, thereby increasing production efficiency. PMS can oxidize polyamine epichlorohydrin (PAE) in pulp manufacturing without damaging the pulp fiber, and has the following advantages in the field of papermaking:
Free from chlorinated (AOX) compounds
Efficient repulping
High fiber yield
Increase productivity
No stainless steel corrosion
Easier and safer operation
Green seal verification
Reduce dependence on virgin fibers

Electronics

PMS is a free-flowing, powdered chemical etcher for copper cleaning and surface treatment in printed wiring board manufacturing. KHSO₅ acts as the active ingredient to provide more efficient copper oxidation. Compared to non-competitive products such as hydrogen peroxide/sulfuric acid and sodium persulfate (SPS), this chemistry provides better etched copper surface morphology with well-defined grain structures that are evenly distributed. PMS chemistry produces optimized grain structures that provide better adhesion for metal plating, dry film, final finishes, and IC packages.  The advantages of PMS application in the field of electronic products are:
Free-flowing powder
Uniform, predictable etching rate
High etching rate
Long bath life
Excellent bonding morphology
High copper load
No stabilizer required
Good rinsing properties

Denture cleaner

PMS is a very effective non-chlorine oxidizing agent that has long been the main detergent ingredient in denture cleaning agent compositions. As a stable powder product, PMS is easy to formulate into granular and tablet compositions. In addition, it has strong oxidation properties to effectively control bacteria. It has excellent water solubility, easy rinsing, no peculiar smell. Faster action than other oxidants, which means shorter soaking times. Furthermore, PMS has excellent compatibility with denture materials, and GRAS oxidation by-product certification is recognized as safe.

Odor control

PMS is very effective in controlling harmful, pungent odors. PMS does not contain chlorine and does not require any chemical activation. It is therefore safer to use and store, with chemical stability in solution for up to 30 days (depending on storage conditions). PMS's high redox potential and fast reaction kinetics enable rapid reaction with volatile organic compounds (VOCs), including:
Hydrogen sulfide / organic sulfide / disulfide / mercaptan / organic amines / quinolines / aldehydes / ketones /synthetic fragrances

Swimming pool and spa water purification

The water in the swimming pool and spa needs to be clear and odor-free. PMS can be used as an oxidizing agent to keep water transparent by oxidizing organic pollutants such as sweat, urine, skin debris, etc. After oxidation, the pollutant particles are more likely to combine into larger particles, which are removed by pool filtration. The pungent smell in swimming pools is generally caused by chloramines. Chloramines are formed when chlorine is combined with ammonia or organic matter in water. Chloramines come in many forms, some of which migrate to the air to produce a strong taste of chlorine, while others remain in the water and can cause skin and eye irritation. Regular use of PMS products helps remove organic contaminants and chlorine before they react to form chloramines. Simply disperse the PMS product into the water body of the pool and let the water circulate for 15 minutes to achieve the effect of purifying the water body.
