Prevention and control: scientific irrigation, according to the different demand for water in different growth stages of rice, reasonable irrigation, implementation of flower water transplanting, inch water sputum, till the end of the sputum (3 to 5 days before ear differentiation), draining the sun for 7 to 10 days, such as The occurrence of low temperature weather below 17 Â°C, can fill more than 15 cm of water layer, deep water protection tires, which is an effective measure to prevent obstacles of low temperature and cold damage; reasonable close planting, is conducive to ventilation and light; scientific fertilization, moderate nitrogen application, increased phosphorus, Potassium fertilizer makes the stalk strong and prevents lodging.
Copper removing agent, lead copper removing agent, lead fire smelting copper removing agent, lead refining copper removing agent, lead copper removing agent for export, crude lead fire smelting copper removing agent, No. 2 lead refining copper removing agent
Bismuth is the impurity which is the most difficult to remove during fire refining of crude lead. lead fire process refined debismuthizing agent is prepared and produced by Luanchuan Hengkai Metallurgical Materials Sales Co., Ltd after research and development for many years. The lead fire smelting novel copper removing agent is prepared and produced by our company. After the copper removing agent produced by our company is used, the copper content in the lead after copper removal is within 0.0002. More importantly, after the copper removing agent produced by our company is used, no pollution is produced (no smoke), the emission of sulfur dioxide is reduced, there is no low-altitude pollution, the operation is simple for workers, the operating environment is improved, and free technical guidance is given for the first-time use.
"Hengkai Metallurgical" brand patent products (patent number: 201808178848) is environmental protection copper removing agent 1#. Environmental protection formula copper removing agent 2# belongs to upgrade products of the copper removing agent 1#. After the copper removing agent produced by our company is used, the copper content in the lead is less than 0.00015 after copper removal. The product is characterized by small usage, no pungent smell, no low-altitude pollution, easier operation and low slag rate. Product advantages: the content of existing copper removing agent in the market is 6%-10%, which is lower than ours. Currently, the company is the only one in China that has passed EIA acceptance. The company adopts the most advanced independently-developed automatic production line to produce copper removing agent. The annual output is 15,000 tons, and the moisture content is less than 0.01%.
