In 2014, the import and export of China's paint industry continued its trend of export growth better than that of imports, but the unit price of imported coatings was still much higher than the unit price of export coatings. The unit price of imported paint is US$5.7/Kg, and the unit price of export paint is US$3.6/Kg.
In May 2014, China's paint industry exported a total of 17 569.2 tons, an increase of 5.4% year-on-year, and the export amount was US$ 59.31 million, an increase of 5.4% year-on-year; the import volume was 14,954.8 tons, a year-on-year decrease of 9.3%, and the import amount was US$ 87.35 million. Declined by 4.5%. From January to May 2014, the cumulative export volume of the paint industry was 75,287.5 tons, an increase of 6.9% year-on-year, and the export amount was 277,330,000 US dollars, an increase of 10.6% over the same period of last year. The average export price of the products was 3,595.95 U.S. dollars per ton; the cumulative import quantity was 70,128.8 tons. The growth rate was 0.4% year-on-year, and the import amount was 399.4 million US dollars, an increase of 1.1% over the same period of last year. The average import price of the products was 5,695.24 US dollars per ton.
As can be seen from the table, the top three rankings for export of paint products from January to May 2014 were Guangdong Province, Shanghai Municipality and Jiangsu Province. The total export volume of the three places accounted for 69.86% of the total export volume of the country. The 67.13% of the total imports of the country all show obvious advantages. Shandong Province, Zhejiang Province and Liaoning Province performed well and ranked second.
WAFER TYPE DOUBLE DISE CHECK VALVE
Wafer check valve is also known as reverse flow valve, check valve, back pressure valve and one-way valve. This type of valve is automatically opened and closed by the force generated by the flow of the medium itself in the pipeline. The valve used to prevent the backflow of the medium belongs to an automatic valve.
Its main function is to only allow the medium to flow in one direction and prevent the flow in the opposite direction.
, Prevent the reverse rotation of the pump and the drive motor, and the discharge of the container medium. Check Valves may also be used on lines supplying auxiliary systems where pressure may rise above system pressure. Check valves are used in piping systems,
The check valve is a valve that automatically opens and closes the valve flap depending on the flow of the medium itself, allowing the medium to flow in one direction, and plays an important role in protecting the pipeline machinery and equipment from water hammer damage. Usually, this kind of valve works automatically. Under the action of fluid pressure flowing in one direction, the valve flap opens; when the fluid flows in the opposite direction, the fluid pressure and the self-coincident valve flap of the valve flap act on the valve seat, thereby cutting off the flow. The working characteristics of the check valve are that the load changes greatly, the opening and closing frequency is small, and once it is put into the closed or open state, the applicable period is very long, and it does not require the movement of moving parts. But once there is a "switching" requirement, it must be flexible,
Wafer check valve, the valve body is cast iron or cast steel, and the valve disc can be made of metal, depending on the performance requirements. The disc can be of all-metal construction, in the form of a rubber pad or rubber ring inlaid on the disc holder, or with a synthetic overlay.
Choose different materials, can be applied to water, steam, oil, nitric acid, acetic acid, oxidizing medium, urea and other media.
