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 which is used for air adsorption and has a filtering function. Background technique [0002] With the improvement of people's material and cultural living standards, interior decoration has become fashionable, and what follows is that the pollution of indoor air is becoming more and more serious. And for most people, regardless of work, study or life, people spend most of their time indoors or in closed spaces such as cars. Although the harm of air pollution to human health has long been recognized by people, people's attention has gradually shifted to the harm of indoor air pollution to human health until the middle of the 20th century. There are many types of indoor air pollution, more extensive pollution sources, and complex influencing factors. The harm to human health is often more serious than outdoor air pollution. Indoor air quality research has become a new and im...
