The main removal methods are as follows:

Ventilation method: put the metal display tower in the ventilation corridor, and let the wind in the corridor dilute the smell of the metal display tower. Advantages: effective, no cost disadvantage: requiring a long time.

Physical adsorption: this method is more complex and will not be described for the time being.

Traditional method: Use fruit or tea leaves to cover the scent. Advantages: it seems that it is less smelly. Disadvantages: this method is just to cover the smell of decoration with another kind of smell.

The harmful gas still exists on the metal display tower all the time, and it has not been reduced much. It can be said that it is a drop in the bucket. So this method is recommended. However, the use of activated carbon colleagues to increase the humidity and temperature of the metal display tower itself can play a certain effect.

Negative ion method: according to research and application, it has been proved that crystal gypsum lamp has a natural anion diffusion function, which can effectively absorb formaldehyde and other harmful gases, remove the negative energy of other rocks and purify environmental energy.

In addition, we can also grow some plants, which can absorb harmful substances.

Cymbidium and Phyllostachys heterophylla can remove harmful substances in the air, Chlorophytum odoratum and aloe are good at absorbing formaldehyde. Milan and Chimonanthus praecox can effectively remove sulfur dioxide, carbon monoxide, and other harmful substances in the air. Rhizoma Arisaematis, ivy, and Tieshu can effectively absorb benzene. It should be noted that the harmful substances absorbed by plants are relatively limited, and they have certain self-damage to plants. It can only be used to fine-tune.

Knowing what the bad-smelling ingredients are, we can take targeted measures to make these odors disappear more quickly.

The components of the bad smell in the paint are tetramethyl benzene, Tianna water, polyester paint, and other chemicals. Most of the paint is composed of three basic substances, namely: organic polymer compounds such as natural resin, rosin, lacquer, tung oil, linseed oil, soybean oil, fish oil, synthetic resin, and other mixed ingredients, which are prepared by the high-temperature reaction, additives, and solvents: such as tetramethyl benzene, Tianna water, polyester paint contains formaldehyde, and metal-free DTI in curing agent, which can cause dizziness and vomiting in light.

There are three environmental indicators: VOC, free formaldehyde, and heavy metals.

VOC (volatile organic compounds)

VOC is the abbreviation of volatile organic compounds (VOC). VOC refers to the organic substances in the paint that do not form a film but eventually volatilize into the atmosphere. Volatile organic compounds (VOCs) will react with oxygen in the air to form ozone. Low altitude ozone is harmful to the atmospheric environment and human health.

Formaldehyde: formaldehyde is a colorless gas with a strong pungent smell. It has the characteristics of volatile and high toxicity. The formaldehyde aqueous solution with 35% - 40% is called formalin. Formaldehyde has a high toxicity. The relative density of gas is 1.067 (air = 1), and the density of liquid is 0.815 g / cm 3 (- 20 ℃). Melting point - 92 ℃, boiling point - 19. 5 ℃. Soluble in water and ethanol. The highest concentration of the aqueous solution can reach 55%, usually 40%. It is called formaldehyde water, commonly known as formalin. It is a colorless liquid with a pungent smell.
