Method used

According to the activated carbon carving product obtained by the process method of the present invention, since the silicon acrylic emulsion has been selected as the molding binder in particular, it can bond the powdered activated carbon into shape, and can make harmful gases, especially in building materials The toluene gas is adsorbed by the activated carbon through the solidified film layer. According to the analysis and test of the analysis laboratory of Zhejiang University of Technology, its adsorption performance is better than that of the commercialized acti...

The invention relates to a method of molding activated carbon sculpture. It includes: mixing and churning up uniformly the activated carbon powder and the water-soluble adhesive by the certain ratio, then dumping it into the forming mold and solidifying, the said water-soluble adhesive is silicone-acrylic emulsion, and the ratio of silicone-acrylic emulsion and the activated carbon powder is 20-150:100. The product solidified in the forming mold can be seen as finished product directly or can be carved into artwork through the conventional carven means. The products get through the method of molding activated carbon sculpture have high adsorption, and its production is convenient. It needs not heating, negatively pressuring, catalysis, pressuring, vacuumizing, maintaining temperature and decompressing repeatedly, so saves energy sources. The products is considered as arts, while also play a part of adsorbing infectant gases. It is very positive and practical to protecting health of people.

Example Embodiment

[0008] Example 1
[0009] This embodiment describes an activated carbon sculpture molding process method, which is to mix powdered activated carbon and a water-soluble adhesive according to a determined ratio, stir uniformly, and then enter the molding mold to form and solidify. The water-soluble adhesive is a silicone-acrylic emulsion. When bonding and curing, a specified amount of defoamer (such as tributyl phosphate) can be added according to the curing requirements of silicone-acrylic emulsion. The ratio of silicone-acrylic emulsion to activated carbon can be 20 parts of silicone-acrylic emulsion in 100 parts of powdered activated carbon. In the ratio of silicone-acrylic emulsion to activated carbon, the ratio of silicone-acrylic emulsion to activated carbon can also be 150 parts of silicone-acrylic emulsion added to 100 parts of powdered activated carbon. The solidified shape in the forming mold can be directly used as a complete sculpture product, or it can be molded and solidified into a block and then sculpted into a handicraft by conventional sculpture means.
[0010] The activated carbon carving products obtained by the process of the present invention, due to the special selection of silicone-acrylic emulsion as the molding binder, can not only bond the powdered activated carbon, but also make harmful gases, especially toluene gas in building materials It is adsorbed by activated carbon through the cured film layer. After analysis and testing by the analysis laboratory of Zhejiang University of Technology, its adsorption performance is better than that of commercially available activated golden black carbon. As shown in Figure 1, ordinary activated carbon and silicone acrylic emulsion are used by weight. The ratio of 100:100 is stirred and molded, and the test result is that the adsorption capacity of the commercial activated carbon is 42 mg/g, and the activated carbon adsorption capacity of the sample obtained in the present invention is 45.6 mg/g. As the activated carbon of the sample obtained in the present invention adopts high-adsorption activated carbon, its adsorption capacity for harmful gases will also be greatly improved.
