A few days ago, Wenzhou Inspection and Quarantine Bureau learned that from January to November this year, Wenzhou exported a total of 676 million pairs of footwear products to US$3.52 billion, up by 23.88% and 41.67% year-on-year respectively. Among them, the export of safety shoes reached 206 million US dollars, for the first time exceeded 200 million US dollars, an increase of 85.74%.
It is understood that safety shoe manufacturers mainly in Ruian area, the number of companies exporting over 10 million US dollars has increased from 3 in the same period last year to 5. The number of exporting countries increased from 113 to 120. Canada, Australia and other countries have the highest requirements for safety shoes, and their exports have increased significantly in the first 11 months, an increase of more than 70%. Some large and mid-to-high end product customers such as puma have increased their purchases in Wenzhou, especially Ruian. The export volume of high-grade safety shoes with a unit price of over US$20 has reached 731,400 pairs and US$17,183,500, an increase of 139 points over 2009. % and 133%, the highest price for safety shoes reached $ 65.47 / double.
According to the relevant inspection and quarantine authorities, safety shoes are a barometer of the international economy and are mainly used in the field of production. The economic recovery in the mining and construction industries has greatly increased the consumer demand for safety shoes. Among them, Wenzhou's export of safety shoes to the EU has increased by more than 100%. %. At the same time, due to the impact of the financial crisis, European safety footwear companies have not been able to recover their previous production capacity. A considerable portion of orders this year have come from the transfer of European orders.
1. Product introduction
Coal-based columnar net gas Activated Carbon is cylindrical, tasteless non-toxic; as high quality anthracite the raw material, by process of crushing, mixing, extrusion, molding, drying, carbonization, activation and made. It has reasonable pore structure, good adsorption properties, high mechanical strength, able to withstand the high temperature, high pressure and not easily broken, easy to regenerate, and low cost characteristics. It is widely used in sewage treatment, gas treatment, solvent recovery, desulfurization and denitrification, nitrogen making machine, air separation equipment, paint shop and other fields.
2. Application
a.Coal columnar net gas activated carbon used for purification, such as chemical raw materials, pharmaceutical chemical synthesis gas, industrial gas, nitrogen, chlorine, hydrogen chloride, ethylene hydrocarbons, ozone, ethane, butane, cracking gas, carbon dioxide and hydrogen used in beverage; atomic facilities exhaust inert gas and remove the pollutants; also separate and purify mixed gas. It also can be used for gas masks and protective equipment disinfection and filtration.
b.Coal columnar net gas activated carbon is mainly suitable for industrial waste treatment, such as waste gas power plant, chemical plant gas, coking plant, smelting plant, oil plant. Coal columnar net gas activated carbon rely on the good adsorption capacity, developed gap, high iodine value can make a cleaning purpose.
3. Adsorption purification principle and process
The physical properties of coal-based activated carbon introduction: it is cylindrical black particles; the physical, chemical properties analysis of carbon is a porous carbon, the highly developed pore structure makes it has large surface area, so it is easy to full contact with toxic and harmful gases in the air (and harmful impurities), so this highly developed capillary and pore structure formed a powerful adsorption force field, which gives the unique adsorption properties of activated carbon.
Adsorption: the organic waste gas passes through the filter removed the solid particulate material, from the upper to the lower into the adsorption tank. The organic matter is captured, absorbed and concentrated by the activated carbon, and the purified air is discharged from the lower part of the tank through the main fan into the atmosphere.
Stop: when activated carbon adsorption reached saturation,it stops to inhalation waste gas; and then blowing up into the steam through the activated carbon bed, which expelled the organic matter from the activated carbon, and the subsequent restoration of desorption, activated carbon activity is recycled.
Hot air drying and cooling: the activated carbon layer after desorption remains 80%-90% steam condensate which can in reducing carbon layer activity; therefore using the hot air to dry, close the steam valve, and then through the air cooling at 25 DEG C, activated carbon can be recovered into the circulation.
