Preparation technology of active carbon for active carbon sheet materials

Abstract

The invention discloses a preparation technology of active carbon for active carbon sheet materials, relating to the technical field of interior decoration, comprising the following steps in order: preparing raw materials, drying, charing, cooling, activating, grinding, crushing and sieving to obtain a finished product of active carbon. The invention has the following beneficial effects: easily available raw material for preparing active carbon, and high iodine sorption value of cocoanut active charcoal, and the prepared cocoanut active charcoal can be applied for house, automobile and various newly-decorated places, can adsorb poisonous and harmful gases of formaldehyde, benzene, halogen hydride to achieve the effects of purifying air, deodorizing, resisting mildew, and absorbing moisture.

Description

Technical field [0001] The invention relates to a preparation process of activated carbon used for activated carbon plates, and belongs to the technical field of indoor decoration. Background technique [0002] With the rapid economic development, people have higher and higher requirements for the environment, especially for the living environment. At present, the walls, floors, etc. used for indoor decoration tend to be wood panels, not only because wood panels are warm in winter and cool in summer, but also because wood panels give people the feeling of being close to nature. However, due to a series of chemical procedures, the wooden board contains a certain amount of volatile organic compounds. Moreover, the wooden board has a certain degree of moisture absorption. Long-term use will cause the wooden board to deform due to moisture absorption and affect the appearance. Therefore, people usually put activated carbon boxes indoors. Because the shape of the activated carbon box...

Problems solved by technology

However, the wooden board contains a certain amount of volatile organic compounds due to a series of chemical procedures. Moreover, the wooden board has a certain degree of hygroscopicity. Long-term use will cause the wooden board to deform due to moisture absorption, which will affect the appearance.

Therefore, people generally place activated carbon boxes indoors. Because the shape of activated carbon boxes is limited, the absorption surface area is small, and the process of making activated carbon is relatively complicated, and it is difficult to obtain materials, which restricts the development of activated carbon.
