In late August, the Shiyan city government issued a circular: The city's 69 yellow ginger processing companies have all shut down! The reason is that these companies failed to meet the discharge standards.
What differs from the past is that this time, Shiyan adopted enterprises that have closed down pollution, such as land resumption, power cuts, business license revocation, and equipment removal.
It is reported that the 69 companies have a production capacity of 5590 tons of saponin, and shut down these enterprises for a loss of 45 million yuan a year. However, the production of one ton of saponin means 500 tons of waste water and 8 tons of waste slag. The acidity of the waste water exceeds the standard by 4 times, the biochemical oxygen demand exceeds the standard by 750 times, and the ammonia nitrogen exceeds the standard by 20 times.
“The public’s happiness index is more important than the economic growth rate.†Luo Yuanhong, deputy mayor of Shiyan City, said that rather than slowing down the rate of increase, Shiyan also never contaminated GDP, and should not destroy the living environment of future generations.
Shutting down the ginger processing company is a painful choice. The relocation of the headquarters of Dongfeng Company made the economy of Shiyan, which was “built for the car and thriving by the carâ€, greatly affected. The medical and chemical industry represented by the processing of yellow ginger was the emerging growth pole of the Shiyan economy. The saponin production in the city accounted for the world market. 20%.
Shutting down turmeric processing companies is only part of the shutdown of "polluting GDP." Since 2002, Shiyan has closed 186 polluting enterprises, involving an output value of 1.9 billion yuan.
Train Parts Casting is one branch of carbon steel precision casting, which is widely used in train markets. Precision Casting Of Train Parts adopts lost wax casting, also called investment casting. In wax pattern process,we mix stearic acid and paraffin wax.
In wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small. In dipping slurry process,most of the suppliers adopt water glass technics in domestic area,but we adopt compound technics or silica sol technics. As you know, carbon steel castings will be much smoother with compound technics (compound of water glass and silica sol technics),this method is so popular with our customers, and the quality is higher than water glass technics, the cost is lower than silica sol technics.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
Our train parts as precision casting products have quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The parts can be made completely based on your specifications such as drawing, design, sample etc.
