Shandong Laizhou Welfare Sodium Co., Ltd. was founded in 1984 and is located in Laizhou, a coastal city in the Golden Triangle bordering Qingdao to the south, Yantai to the east, and Weifang to the west.It is a professional manufacturer of liquid and solid sodium silicate.The company is located in Chengguo Town, Laizhou City, Shandong Province. It is 20km away from Laizhou Port in the north, 0.2km away from Weiwu Expressway in the east, and 206 National Highway in the west. It has convenient transportation and superior geographical location.Currently covering an area of 150,000 square meters, with a total investment of 250 million yuan, and an annual output of 450,000 tons of solid sodium silicate, with a total of four sodium silicate production lines, it is currently the largest sodium silicate production enterprise in Asia.
First-line kiln: The kiln area is 72 square meters and the daily production capacity is 200 tons.Second-line kiln: The kiln area is 88 square meters and the daily production capacity is 250 tons.Third-line kiln: The kiln area is 106 square meters and the daily production capacity is 300 tons.Fourth-line kiln: The kiln area is 176 square meters and the daily production capacity is 500 tons.
A zero-water sodium metasilicate production line with an annual output of 18,000 tons. This device has been improved and perfected on the basis of digesting and absorbing domestic and foreign technologies. The products produced are round, white, and have good rolling properties.
The company built a new quartz sand production workshop in 2017, using domestic leading magnetic separation equipment to process the quartz sand again to remove impurities and reduce the content of heavy metals in the quartz sand. The daily production capacity reaches 2,000 tons.
The company has the most advanced testing equipment in the country, which can detect more than 20 metal elements in sodium silicate. The assay level can reach PPB level, which is in line with international standards and provides a stable basis for the company's products to connect with the indicators of foreign customers. Base.
In order to actively respond to General Secretary Xi’s call of “lucid waters and lush mountains are invaluable assets”, our company invested more than 30 million yuan in additional environmental protection equipment to ensure that flue gas emissions meet the ultra-low emission standards required by the Ministry of Environmental Protection.This set of equipment was jointly designed and developed by experts from the Institute of Environmental Engineering of the Chinese Academy of Sciences, Beijing University of Technology and the Chinese Chemical Catalysis Committee.
The external emission indicators of our company are dust particles within 10 mg/m³, sulfides within 50 mg/m³, and nitrogen oxides within 100 mg/m³. We have already reached the ultra-low emission standards required by the Ministry of Environmental Protection ahead of schedule.At the same time, after being processed by our equipment, there will be no secondary pollution. At the same time, our company has rainwater and wastewater collection tanks. During the rainy season, the rainwater in the factory area is collected through underground pipes and then uniformly enters the rainwater collection tank. After sedimentation treatment It is transported back to the production workshop for recycling and is not discharged to the outside world. The wastewater generated during the production process comes from the raw material cleaning process. This part of the wastewater is concentrated and filtered and then all enters the collection tank. It is transported back to the production workshop through pipelines for recycling and is not discharged to the outside world.
