"Children's furniture (renovation effect map) general technical conditions GB28007-2011" (hereinafter referred to as "new national standard") has been implemented for one and a half months, but when reporters visited the Beijing market in mid-September, they found that including love, I love my family, cute and so on. Many of the famous children's furniture brands have turned their attention to the new national standard, and the exhibition hall is still full of non-compliant old products. According to industry insiders, the regulatory gap in the new national standard for children's furniture is an important factor that causes manufacturers to slack off and openly violate regulations. Many favorite big brands sell non-compliant products. On August 1, the new national standard for children's furniture was officially implemented. This special (renovation effect map) for the implementation of children's furniture mandatory standards, after the implementation of a month and a half, the reporter surveyed the Beijing home market found that more love, I love my family, cute and many other children's furniture industry famous The brand still regards the new national standard as nothing, and the exhibition hall is filled with old products that are not in compliance. On September 15th, the reporter saw in the many favorite exhibition halls of the Lan Jingli family Dazhongsi store, an obvious old bedside table (renovation effect picture), the drawer is installed with a roller sliding device, the reporter took a little effort, the drawer It will fall off, and the new national standard stipulates that the drawer push-pull parts should have anti-pulling devices. Aijia Home West Fourth Ring store's favorite exhibition halls are selling a large number of samples, and a product is equipped with a bright glass component, which violates the requirements of the new national standard of less than 1.6 meters. Known as the "global children's furniture quality assured brand of choice", I love my family, and the emphasis on the new national standard is no better than love. In the blue Jingli family Dazhongsi shop, I love my home showroom. A large wardrobe (renovation effect picture) only has a vent hole inside, and according to the new national standard, the confined space should be set to two unhindered. Ventilation opening. In the home of the home of Jinyuan, I love my family, some of the products being sold are not even anti-dumping devices, and they are sung against the new national standard. The famous children's furniture brand in Beijing is so cute that it also does not comply with the new national standard. The new national standard stipulates that the product can be exposed to a dangerous outer angle of less than 1.6 meters, and the rounding radius should be no less than 10 mm. However, in the lovely multi-show hall of Aijia Home West Fourth Ring Store, some bookcases (decoration renderings) The corners of the wardrobe are very distinct. Some of the movable parts of the store do not have any warning signs, nor do they meet the requirements of the new national standard. "On the products with folding or adjusting devices, warnings such as 'warning, careful pinching' should be marked." In addition to the basic protection measures are not well done, most of these brands are not able to produce test certificates in the first place in terms of the limit standards for harmful substances. I have just experienced the "contamination door" of formaldehyde, but I have shown the test report to reporters, but only the test results of four kinds of migratory elements are shown above, and the test standards of eight kinds of migratory elements are specified in the new national standard.

1. Product introduction
Coal-based Column Denitrification Column Activated Carbon is cylindrical black particles. It has many characters, such as high porosity, high sulfur capacity, high desulfurization efficiency, large surface area, light weight, strong adsorption capacity, wear resistance, good water resistance, low air resistance, easy regeneration, not easy to break under high pressure etc. It is a commonly used in adsorbent.
2. Adsorption purification principle and process
Coal-based denitrification Activated Carbon is divided into large pores (pore size greater than 50nrrt), the middle hole (pore size between 2 ~ 50nm) and micro-pore (pore size less than 2nm) three categories.
The denitrification activated carbon is by active carbon`s adsorption and catalytic activity of activated carbon. The strong catalytic effect of the active carbon for sulfur dioxide in gas, and a small amount of Oxygen in the oxidation reaction, the reaction of elemental S adsorbed the surface of activated carbon. When activated carbon desulfurization agent the adsorption reaches saturation, the desulfurization efficiency decreased obviously, it must carry on the regeneration. The regeneration of active carbon adsorption depends on the material, sulphur began to melt under atmospheric pressure is 190 degrees, 440 degrees Celsius will sublimate into gas, therefore, the general use of superheated steam temperature of about 450-500 degrees Celsius for the regeneration of activated carbon desulfurization agent. When the desulfurization agent reach high temperature, the elemental sulfur separate out activated carbon, the precipitation of sulfur into sulfur recovery pool, water cooled to form solid sulfur.
