Abstract

The invention discloses a powder-shaped active carbon moulding and regenerating method, which comprises the following steps: 1. allocating raw material with 60-80% carboxyl butylbenzene latex, 9-11% methyl phenyl latex, 7-9% polyvinyl alcohol and 4-20% carboxymethyl cellulose; blending completely; making the latex; 2. placing composition with 45-55% powder-shaped active carbon, 15-25% water, 4-6% alcohol and 20-30% latex in the step 1 in the blender to stir half an hour; 3. placing the composition in the mould; providing 100t/m2 pressure on the hydraulic press for 10 min; obtaining block-shaped material; 4. stewing the blocked material under normal temperature for 48h; transmitting the material to thermostatic chamber at 30-100 deg.c for 8-12h; 5. placing the material in the thermostatic chamber at 180-220 deg.c for 8-12h; obtaining the product.

Description

Technical field [0001] The invention relates to the reprocessing of powdered activated carbon, in particular to a method capable of treating powdered activated carbon into block activated carbon available for engraving and the obtained block activated carbon product. Background technique [0002] Activated carbon is a very good adsorbent. It uses charcoal, various fruit shells and high-quality coal as raw materials, and uses physical and chemical methods to crush, sieve, activate catalysts, rinse, dry and screen raw materials. Manufactured through a series of processes. But for a long time, the finished products of activated carbon exist in the form of powder (or granular), which is not easy to store, and has the consequences of short timeliness and easy pollution due to the large surface area and easy adsorption of foreign substances. And it can only be used as a cleaning and drying material for adsorption, and it cannot be further processed in appearance to produce a tech...
