Abstract
The present invention discloses a superfine active compound adsorptive indoor air purifying agent. Activated attapulgite clay or sepiolite clay after superfine processing is uniformly mixed with zeolite according to a proper proportion for polymeric granulation and drying; the attapulgite clay or the sepiolite clay and the zeolite are mixed with granular active carbon according to a certain proportion for obtaining the superfine active compound adsorptive indoor air purifying agent of the present invention. The substances have large specific surface areas and abundant and complicated molecular hole passages. Because the molecular hole passages of the substances are respectively matched with the sizes of pollutant molecules such as benzene, toluene, xylene, methanal, ammonia gas, radioactive radon, etc., harmful gas molecules as adsorbates in the process of movement are absorbed in the molecular hole passages of the purifying agent because of the function of van der waals force. Particularly, when the purifying agent is installed on one end of a blower for forcing indoor gas to pass from the purifying agent, harmful gas in indoor air is rapidly filtered and absorbed in the molecular hole passages of an adsorbing agent matched with the sizes of the molecules. Consequently, the present invention achieves the goal of purifying air.
Description
Technical field
The present invention relates to a kind of indoor air purification agent; especially a kind of air pollution that causes at modern building and indoor decorating and carry out the air purifying preparation of compound adsorption cleaning; be applicable to the air cleaning in the vehicles such as car, ship simultaneously; belong to environmental protection technical field, be specifically related to superfine compound active adsorbing absorbent-type indoor air purification agent.
Background technology
Modern city and towns resident about 80% time is spent in the indoor and vehicles, and various New Building Materials, building additive and decoration have been built generally contaminated into room air.Newly dispatch from the factory or newly modify, paint after the vehicles such as car, ship in the organic pollution of higher concentration is also arranged.
Existing air cleaner mainly plays the effect of filtering particle float and sterilization, and is not ideal enough to the clean-up effect of organic pollution and ammonia, radioactive radon etc.
Summary of the invention
