Embodiment 1

[0030] Containing 99% by mass ratio of alumina, 0.6% by mass ratio of 2,4-pentanedione, and 0.4% by mass ratio of formaldehyde, the visible color-changing indicator deodorant is placed in 50ppm of methylamine (simulated odor ingredients) and a relative humidity of 90% in a closed space, after 5 hours, it was observed that the color of the deodorant began to change. Continue to place it, the color will continue to deepen, until the color does not continue to darken visually, you can replace it with a new deodorant, and continue to absorb and remove. When the new deodorant is put in, the original color remains and no longer changes, indicating that the polluted gas in the space has been basically removed. After testing, the relative humidity in the closed space has dropped to 20%, and the concentration of methylamine has dropped to below 1ppm.

Embodiment 2

[0032] Containing 99.2% by mass of silica gel, 0.4% by mass of 2,4-pentanedione, and 0.4% by mass of acetaldehyde, a visible color-changing indicator deodorant, placed in 50ppm of ammonia (simulated odor component ), in a closed space with a relative humidity of 90%, after 8 hours, it was observed that the color of the deodorant began to change. Continue to place it, the color will continue to deepen, until the color does not continue to darken visually, you can replace it with a new deodorant, and continue to absorb and remove. When the new deodorant is put in, the original color is maintained and no longer changes, indicating that the polluted gas in the space has been basically removed. After testing, the relative humidity in the closed space has dropped below 20%, and the concentration of methylamine has dropped below 1ppm. .

Embodiment 3

[0034] Containing 99.3% by mass of attapulgite, 0.3% by mass of 2,4-pentanedione, and 0.4% by mass of benzaldehyde, a visual discoloration indicating deodorant, placed in 50ppm of methylamine (simulated Odor components) and a closed space with a relative humidity of 90%, after 6 hours, it was observed that the color of the deodorant began to change. Continue to place it, the color will continue to deepen, until the color does not continue to darken visually, you can replace it with a new deodorant, and continue to absorb and remove. When the new deodorant is put in, the original color is maintained and no longer changes, indicating that the polluted gas in the space has been basically removed. After testing, the relative humidity in the closed space has dropped below 20%, and the concentration of methylamine has dropped below 1ppm. .

Abstract

The invention discloses a novel visual color change indication deodorant. The deodorant mainly comprises 2,4-pentanedione, aldehyde and a drying agent in a mass ratio of (0.01-5):(0.01-5):(90-100). The deodorant reacts with a main odor component, namely water-ammonia dimer in high-humidity air to form a colored product while water is absorbed, so that the color change indication of odor is generated; and when the color of the deodorant is deepened, a user can be informed of timely replacing a fresh deodorant, and a deodorization effect is improved.

Description

technical field [0001] The invention belongs to the fields of material science and environmental protection, and in particular relates to a novel visual discoloration indicating deodorant. Background technique [0002] The malodorous gases produced by kitchens and bathrooms, urban sewage treatment plants, landfills and some factories in daily life have seriously disturbed people's normal life and endangered people's health. The harm of stench is mainly manifested in the impact on the human body, which brings unpleasant feelings to people. Common symptoms include headache, nausea, loss of appetite, physiological disorders, emotional loss, insomnia, and respiratory diseases. The high concentration of stench can even cause acute illness and death among the polluted population. As a kind of environmental pollution, stench has become one of the seven major public hazards in the world. In the family, the odor control of the refrigerator, which is a closed space, is an important...
