At present, Wenjian is located at the bank side of Qiandao Lake, is next to national highway 320, Jinqian railway, and Hangxinjing expressway; we enjoy good location.Basing the advantages of local limestone resource, Wenjian now can produce 60,000 T/A of calcium hydroxide and 10,000 T/A of calcium oxide. According to your demands, our calcium hydroxide series include: High pure calcium hydroxide for epichlorohydrin, Ca-based grease lubricant, bleaching agent and calcium stearate; Food/medicine additive calcium hydroxide for water treatment, the synthesis of high molecular HA, Konjak, Vitamin C phosphate ester and calcium replenishment agent; Environment friendly calcium hydroxide for of sewage treatment, stack-gas desulfurization and refuse burning; Special calcium hydroxide for building coating, construction and decoration. High pure calcium hydroxide is the patented product, with high purity, good whiteness (≥94 degree) and excellent fineness. The features of Food/medicine grade calcium hydroxide are high purity, good whiteness (≥94 degree), small size(D50%≤5um) and stable ingredients, its impurities(As, Pb And Co) is not more than 1ppm. The characteristics of building coating calcium hydroxide include even whiteness, good fineness, low impurities and low calcium oxide.

We have developed liquid calcium chloride for the treatment of industrial waste water from desulfurization of calcium carbonate in power plant and for sugar industry. The biggest advantages of the products: It has no secondary pollution, and can protect the human health in operation, It is time/labor effective and very convenient to use.
