The unpleasant taste of the paint is: tetramethylbenzene, water, polyester paint and other chemicals. Most of the paint consists 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, after high temperature reaction, additives and solvents. : For example, tetramethylbenzene, Tianna water, polyester paint contains formaldehyde, and there is metal free DTI in the curing agent, which can cause dizziness and vomiting.
Knowing what the unpleasant ingredients are, then we can take certain measures to make these odors disappear more quickly.
There are three environmental indicators: VOC, free formaldehyde, heavy metals.
VOC (Volatile Organic Compound)
VOC is the abbreviation of volatile organic compounds. Volatile organic compounds are organic substances that do not form a paint film in paint and eventually volatilize into the atmosphere. Volatile organic compounds react with oxygen in the air to form ozone, which is harmful to the atmosphere and human health.
Formaldehyde: Formaldehyde is a colorless, highly irritating gas. It has the characteristics of being volatile and highly toxic, and 35% to 40% of the aqueous formaldehyde solution is called formalin. Formaldehyde is highly toxic. The gas has a relative density of 1.067 (air = 1) and a liquid density of 0.815 g/cm3 (-20 ° C). Melting point -92 ° C, boiling point -19.5 ° C. Soluble in water and ethanol. The concentration of the aqueous solution is up to 55%, usually 40%. It is called formalin, commonly known as formalin, and is a colorless liquid with a pungent odor.
There are several main ways to remove:
Ventilation method: Place the display rack in the ventilation aisle, let the wind of the aisle dilute the smell of the display rack. Advantages: good effect, no cost disadvantages: long time.
Physical adsorption: This method is more complicated and is not stated at the moment.
Traditional method: fruit, tea covered with odor. Advantages: It seems that the smell is small. Disadvantages: Just use a smell to cover the smell of the decoration. The harmful gas has always existed on the display rack and has not been reduced. It can be described as a drop in the bucket. So this method is recommended. However, colleagues who use activated carbon can increase the humidity and temperature of the display rack itself to have a certain effect.
Negative ion method: According to research and use, crystal gypsum lamp has a natural negative ion spreading function, which can effectively absorb harmful gases such as formaldehyde, remove negative energy of other stone, and purify environmental energy.
In addition, we can also raise some plants that can absorb harmful substances.
One leaf orchid and monstera can remove harmful substances in the air. Tiger spider orchid and spider plant, aloe vera are good hands to absorb formaldehyde, Milan, and plum can effectively remove harmful substances such as sulfur dioxide and carbon monoxide in the air. Araceae, Ivy, and iron trees can effectively absorb benzene. It is worth noting that plants absorb more harmful substances and have some damage to plants. Can only play a fine-tuning role.
