Photoresist and polyimide (PI) recycling equipment

This technology has been widely used in a well-known photoelectric TFT-LCD color filters (Color Filer), TFT, CELL PI process. The research team focused on the photoresist composition and its chemical properties analysis by using the company's patent. The composition and chemical properties of recycling liquid photoresist is same to the original photoresists.

Ammonium sulfate crystal drying equipment

Ammonia nitrogen wastewater, which is common in semiconductor factories, is removed by thin film and other methods, and then sulfuric acid is used for adsorption. The ammonium sulfate recovery liquid is formed, and it is formed into ammonium sulfate crystals through the chemical crystal drying technology, so as to reduce the waste recovery and reuse in the plant.

Precious metal recycling equipment

If the process wastewater contains valuable metals, such as gold, palladium, copper, nickel, etc., the system design will design electrolysis or resin adsorption methods based on water quality concentration and characteristics to recover valuable metals in water. The principle of electrolysis is that waste water passes through an electrolyzer to reduce and recover positively charged metal ions at the cathode; the principle of adsorption is to use a chelating resin to remove specific metal ions in water, then regenerate after saturation, and recover highly concentrated valuable metal ions in the regeneration liquid.

Equipment for converting cryolite from waste hydrofluoric acid

The three major domestic technology industries, semiconductors, liquid crystal display panels, and solar cells, generate a large amount of waste hydrofluoric acid. ReTech develops a system module equipment that can efficiently treat high-concentration hydrogen fluoride waste liquid on the site, and specifically produces high-quality cryolite crystals, to recover the fluorine element and fundamentally solve the problem possible environmental risks and environmental protection problems caused by cleaning and disposal, avoiding the factory to mix the hydrogen fluoride waste liquid into the wastewater treatment plant, effectively increasing the amount of water available for water recycling in the entire plant and reducing the treatment cost of subsequent water recycling .
