PRODUCTIONCAPACITY
Factory Show
Relying on years of technical accumulation in the environmental protection field, we focus on the R&D and supply of alum products, mainly engaging in various specifications of alum. With stable quality and diverse categories, we empower the development of many industries around the world. This white crystal with a thousand-year application history has shown new value under our professional control—it is not only an efficient coagulant in sewage purification to protect ecological cleanliness, but also a high-quality aluminum tanning agent in the tanning industry to endow leather with flexible texture. It is also a core auxiliary in dye, papermaking, glass, medicine, printing and dyeing and other fields, connecting every key link of the industrial chain. At the same time, it plays an important role in pigments, electroplating, starch and other industries. Food-grade products can also be used as safe buffering agents and leavening agents to meet multi-scenario needs.
