Problems solved by technology

However, the operating temperature of the catalyst used to catalyze the oxidation of formaldehyde is usually much higher than room temperature, and it is difficult to meet the requirements of normal temperature and pressure and low energy consumption for indoor air purification. 2 O and CO 2 Only by using high-quality materials can we hope to realize the practical application of catalytic oxidation technology in the purification of formaldehyde in indoor air.

Abstract

The invention relates to an air purifying agent which comprises the following raw materials by mass: kieselguhr powder, zeolite powder, medical stone powder, tourmaline powder, activated carbon power, sepiolite powder and titanium dioxide powder. The air purifying agent is prepared by the steps of (1) mixing the kieselguhr powder, the zeolite powder, the medical stone powder, the tourmaline powder, the activated carbon power, the sepiolite powder and the titanium dioxide powder; (2) granulating a mixture obtained in the step (1); and (3) drying the granulated mixture obtained in the step (2). The air purifying agent disclosed by the invention is large in specific surface area and uniform, has a good effect for adsorbing and decomposing harmful substances in air and is an ideal selected material suitable for environment purification in closed spaces such as a room and an automobile and for various air purifiers.

Description

Technical field [0001] The invention relates to a purifying agent, in particular to a purifying agent used for air adsorption and having a filtering function. Background technique [0002] With the improvement of people's material and cultural living standards, indoor decoration has become fashionable, followed by more and more serious indoor air pollution. And for most people, regardless of work, study or life, people spend most of their time in enclosed spaces such as indoors or cars. Although the harm of air pollution to human health has long been recognized, it was not until the middle of the 20th century that people's attention has gradually shifted to the harm of indoor air pollution to human health. There are many types of indoor air pollution, more extensive sources of pollution, and complex influencing factors. The harm to human health is often more serious than outdoors. Indoor air quality research has become a new and important part in the field of environmental scie...
