[China Aluminum Network] Anodization (anodic oxidation) is the use of metal or alloy parts as anodes, and electrolytic methods are used to form oxide films on the surface. The metal oxide film changes the surface state and performance, improves its corrosion resistance, enhances its wear resistance and hardness, and thus protects the metal surface.
How to distinguish between anodized 1, anodized antistatic, electric meter red and black poles lightly pressed aluminum surface, the pointer reading is very small or even 0, counterfeit goods pointer readings, that the surface conductivity, and the reading jumps indefinitely, that the surface film is not uniform;
2. After anodizing the surface, the density is very thick, no fumes will be kept without fumes, and fingerprints will not be left after repeated touching;
3, other anti-products in appearance and the import panel is very similar, but carefully distinguish between those materials can be found on the surface lack of metallic luster, feels rough, white material;
The anodized aluminum alloy sheet has a high requirement for the aluminum substrate, and the purity of the aluminum material used as the anodized aluminum is rather high. Of course, the higher the purity of aluminum, the higher the price, which is one of the reasons for the high price of anodized aluminum. Therefore, there are many counterfeit anodized aluminum in the market, and consumers should pay attention to their authenticity. How to identify its authenticity? For the average consumer, there is a simple and easy way to look at whether the surface of the material has a metal texture. The real anodized aluminum oxide film looks and feels like it is formed with the metal itself, without artificial coverage. Feeling up.
1. Product introduction
The coal-based net gas Granular Activated Carbon with high quality Anthracite as raw material, by block crushing production technology refined processing; the appearance is black particles. It has large pore specific surface area and specific volume, reasonable pore structure, good adsorption properties, high mechanical strength, good wear resistance, structural stability, small gas resistance, easy regeneration, low regeneration loss, low cost, not easy to break under high pressure and high temperature and other characteristics.
2. Application
a. The coal-based net gas granular Activated Carbon is mainly used for the purification of poisonous gas, waste gas treatment, purification of industrial and domestic water.
b. The coal-based net gas granular activated carbon is also used to chemical raw materials, pharmaceutical chemical synthesis gas, industrial gas, carbon dioxide and hydrogen for beverage, nitrogen, chlorine, hydrogen chloride, ethylene hydrocarbons, ozone, ethane, butane, cracking gas, inert gas, coal gas, coke oven gas, natural gas, purification of sulfide in flue gas. Purification and exhaust in atomic facilities.
c. The coal-based net gas granular activated carbon is applied to cigarette filter, decoration, indoor air purification (remove formaldehyde, benzene and other harmful gas), new furniture, cabinets / drawers / refrigerator, can also be placed inside the shoes to deodorization.
d. The coal-based net gas granular activated carbon used for biochemical, paint industry, underground sites, leather factories, animal breeding sites for air purification and deodorization.
3. Process
Coal-based granular activated carbon with high quality anthracite as raw material, it produced by high temperature steam, and by carbonization, activation, crushing and sieving process.
4. Transportation and Packing
Woven bag, lined with plastic film bags, each 25kg can also be packaged according to customer demand. The product should be placed in a cool and dry place during storage; When transportation, it prevents to mixed with hard materials, to prevent carbon particles broken that affecting the quality of packaging, to prevent breakage. To avoid leakage or mixed with debris; to avoid water, oil and fire.
