Some time ago, the investigation of mahogany furniture in the Jinan market found that there was indeed a concept of confusion, shoddy and so on. In order to let the audience friends who have already purchased the mahogany furniture or intend to purchase such furniture have a heart, the experts from the Redwood Testing Center of the Shandong Provincial Fiber Inspection Bureau have made some simple household identification. As a result, the first three consecutive identifications of the three, even no one of the mahogany was said to be genuine. Is this really a coincidence or is it really difficult to find the real thing? Yesterday morning, the reporter and the experts of the Redwood Testing Center started the second batch of public welfare appraisal activities. Can we find the real mahogany furniture this time? "We haven't bought it from Jinan. We bought it directly from Guangdong." Mr. Zheng lives in Luneng Kangqiao Community, Jinan City. He told reporters that because he was afraid of buying fake goods, the mahogany of this house was specially pulled from Guangdong. of. However, no experts have begun to observe. Mr. Zheng’s words made the reporter’s heart cool: “I said it was Brazilian rosewood at the beginning. He said so.†Although not professional, through this interview, The reporter already knows that there is no such thing as Brazilian rosewood in the national redwood standard. If it is Brazilian rosewood, it is a common name. The Chinese name of this wood should be called Guyi Sumu. Sure enough, through careful observation, experts at the Redwood Testing Center quickly verified the furniture materials of Mr. Zheng’s home. It is the so-called Brazilian rosewood, but it has nothing to do with redwood. It also belongs to a red and precious hardwood, but it does not belong to the current redwood. It seems that Mr. Zheng is a white ran in Guangdong. Is the luck of the next one better? "When I bought it, I said it was mahogany, rosewood, that is, a kind of mahogany." In the Shilihe Keyuan Community, Mr. Liu and his wife said that their own set of mahogany sofas is beautiful: "My son-in-law gives Buy, he said that there is a collection of value." But after expert observation, a few minutes later, another bad news came out. Mr. Zhang's furniture, from a macroscopic point of view, does not belong to the national standard mahogany, the initial judgment should belong to the iron wood beans, commonly known as red sandalwood. It seems that both Mr. Zheng and Mr. Liu are both flickered by the name that sounds like a mahogany, and Mr. Shan in the Yitong Garden is actually a bad thing. "The bed that he told me at the time was rosewood." What is even more terrible is that the mahogany furniture of Mr. Shan’s house is far more than this one. Because of his love, all the furniture of Mr. Shan’s house from the living room to the bedroom is the selected mahogany. But wait for the experts to carefully read the lap. The tragedy finally happened. "Preliminary judgment is not the national standard mahogany, if he wrote you the mahogany, you can find him." The result of the continuous identification of three furniture, but no one is the real mahogany. In order to allow everyone to be less fooled in the future, and to find out whether the furniture they bought is redwood, the experts of the Redwood Testing Center decided to launch a centralized public welfare identification activity at Jinan Fuya Home at 9:30 am. At that time, you only need to take a small piece of mahogany furniture, such as a drawer, to the site to be authenticated by an expert.
1. Product introduction
Coal Columnar Activated Carbon with high quality anthracite as raw material, its appearance is generally black cylindrical Activated Carbon. Generally by powder materials and binder by kneading, extrusion molding by carbonization and activation processes, has developed pore structure, large surface area, strong adsorption capacity, high mechanical strength, easy to regeneration and low cost. The coal column activated carbon has excellent and broad development prospects in the future market.
2. Application
Column activated carbon is widely used in industry and agriculture, such as petrochemical industry CAUSTIC-FREE (refined mercaptan), ethylene desalted water (refined filler), catalyst (palladium, platinum, rhodium, etc.), water purification and sewage treatment; water treatment and protection in electric power industry; governance, waste gas and harmful gas purification in environmental protection industry; chemical catalyst and carrier, gas purification, solvent recovery and oil decolorization, refining in chemical industry.
3. Adsorption purification principle and process
a. Activated carbon widely used in city drinking water advanced purification and sewage treatment, removing more than chloride, deodorization; high pure water purification materials, advanced artificial mineral production raw materials; large-scale boiler removed the COD and other harmful impurities, which can improve the boiler efficiency and prolong the service life of the boiler; it also can effectively remove the COD of water, pigment, odor and other toxic. Large Granular Activated Carbon can fill the filter and purify the air.
b. Activated carbon widely used in industrial waste-water treatment, effectively deodorization, effectively remove harmful substances to improve water quality. Most powdered activated carbon used for sewage treatment sometimes used for granular activated carbon. Generally activated carbon used in water treatment, the surface area is not too large, but the transition pore has more and larger average pore size.
