WEDM is carried out in the working fluid medium. The insulation performance of the working fluid plays a role of deionization in the process of pulse discharge, accelerating the cooling of electrodes and workpieces in the process of machining, and making the corrosion products suspended and discharged from the discharge gap. The quality of working fluid will have a great influence on cutting speed, surface roughness and machining accuracy. As a low-speed wire cutting process with high-precision parts, it naturally has higher requirements on the quality of working fluid, which requires deionized water to have lower conductivity (generally, the conductivity is less than 20μs/cm).

Sunresin has developed a new vanadium extraction resin based on its own experience and technology in resin R&D and application process optimization. After industrial verification, compared with conventional anion exchange resin, the resin has higher adsorption capacity and strength, better selectivity for pentavalent vanadium, and more outstanding anti pollution ability, well-received by industry production enterprises.

Phenolic compounds are important chemical raw materials and chemical intermediates, which are widely used in the production and processing of dyes, pesticides, adhesives, developers, etc. In the process of the use and synthesis of phenolic compounds, phenolic wastewater will inevitably be produced.

In the face of the industry problem of the treatment of chlorinated hydrocarbon waste gas, Sunresin creatively introduces resin adsorption technology to the treatment of chlorinated hydrocarbon waste gas. Using the high selective adsorption between the special resin skeleton molecule and the chlorinated hydrocarbon molecule, combined with the complex pore structure design inside the resin, it realizes the efficient adsorption and interception of chlorinated hydrocarbon molecule in the waste gas, and carries out resource recovery. Industry verification shows that the recovery rate of adsorption and removal of chlorinated hydrocarbon molecules by Sunresin's special resin and supporting treatment device of waste gas treatment is over 99%, and the export is stable and up to standard. The products and technologies of waste gas treatment resin have been widely recognized by relevant enterprises.

SEPLITE®LSC710 is a macroporous weak acidic cationic resin with iminodiacetate chelating active group can provided high selectivity chelating resin for copper separation and recycling from Adipic acid spent CML, copper recycling ratio almost can reach to 99%.

Chromatography technology is an important technology in the field of modern separation.

The excellent strength performance of Sunresin Seplite® LSF907 resin in industrialized long-cycle operation treatment has been affirmed and praised by industry users; the advent of Seplite® LSF907 resin has given the sugar alcohol industry a choice and less issue; Sunresin will also makes every effort to strive to let this star product benefit the majority of user companies as soon as possible.

Strong acid ion exchange resin is a cation exchange resin whose main exchange group is a sulfonic acid group (-SO3H), which can be used repeatedly. The use of ordinary mineral acids is the same. Softening strong acidic ion exchange resins must use special catalyst type resins because it also affects the reaction rate of hydrogen ion release rate, pore size, and crosslinking degree.
