Introduction of the performance and application of liquid ammonium-free deashing agent TJ-A3607E

As the market pays more and more attention to environmental protection, the requirements for ammonia nitrogen emission are also very strict. It is generally required to use ammonium-free deashing. However, the ammonium-free deashing agent currently on the market contains boron, and boron has reduced activity against sewage treatment microorganisms. risk. TJ-A3607E of Tingjiang is a liquid ammonium-free deashing agent, does not contain ammonia nitrogen, does not contain boron, and has good cushioning properties, uniform and safe deashing. It is a new type of environmentally friendly deashing agent.

 

The main component of the liquid ammonium-free deashing agent TJ-A3607E is an organic acid and a buffer salt complex. The appearance is a colorless transparent liquid, anionic, pH (1:9) 5.5 ~ 7.5.

 

The product is free of ammonium salts and boron salts. It is a clean, safe and efficient deashing agent. It has a balanced de-ashing and permeation speed and mild action. It can completely remove the adsorbed and combined lime in the skin. It has excellent buffering performance, and the pH of the bath is stable at 7.5-8.5 throughout the deliming process, avoiding the problem of deashing quality due to sudden drop in bath pH at the initial stage of deashing. The surface of the naked skin after deashing is clean, smooth and flat, and can effectively reduce the growth pattern and improve the leather yield.

 

TJ-A3607E can completely replace the traditional ammonium sulfate and ammonium chloride for the deashing of various original thicknesses and split gray scales, greatly reducing ammonia nitrogen content and reducing environmental pollution during the deliming process.
