How Made:
Potassium sulfate is refined from naturally occurring mineral salt deposits or by chemical synthesis. Naturally occurring potassium deposits, referred to indiscriminately as "potash", are usually the source of one or more ingredients of synthetic production.
The deposits are found as a conglomeration of potassium chloride (muriate of potash, KCl, or MOP), potassium sulfate (sulfate of potash, or SOP), and potassium nitrate (nitrate of potash, KNO3, or NOP). Deposits are predominantly mined, while some are obtained through solar evaporation of natural brines from saline lake beds.
Potassium chloride is the most abundant mineral found in deposits. Individual potassium salts and any impurities are separated through physical dissolution processes.
Functionality:
Potassium sulfate is commonly used as a specialty fertilizer on crops that are sensitive to soil chloride levels, such as potatoes, lettuce, tobacco, avocados, peaches, and legumes.
It is also used in cases where chloride build up may be problematic. Mined and synthesized potassium sulfate are identical, and thus are functionally interchangeable.
Worldwide, almost all technical grade potassium sulfate production (>99%) is used in agriculture. The remaining SOP is used in a wide range of industrial uses and for manufacturing potassium alum, potassium carbonate, and glass.
We established in 2004, is located in jinzhou city, hebei province. We joinville is one of the largest chemical industry base of hebei, Our annual sales, can achieve 200 million yuan.
We are a professional chemicals manufacturer, our products are divided into three categories, agricultural fertilizer, leather chemicals, washing chemicals. We produce ammonium sulfate 200000 tons a year in the field of agricultural fertilizer, 50000 tons a year in the field of leather chemicals we produce formic acid, glacial acetic acid, 50000 tons, 30000 tons of sodium formate. We produced every year in the field of XiDiPin sodium tripolyphosphate, 30000 tons, 20000 tons of SLES, LABSA10000 tons.
Now our main markets in Asia and Europe, to the future we will set up sales network in more than 200 countries around the world.
Honesty is our principle in business, the product quality is fundamental to our survival, we want all our customers, have a chance to visit our factory, we will establish a solid and reliable cooperation relationship!
