Safety and health are one of the most important measurements in home decoration. Whether it is a top-level luxury decoration with an unlimited budget or a decoration with a tight budget to spend money on, safety, health, and environmental protection will always be given top priority. But when it comes to the odor of harmful gases that affect indoor air quality after renovation, I believe most homeowners are not very familiar or know it well. Now let's listen to Jason's gypsum board editor to reveal one by one.
First, let's talk about what harmful gases are there. The well-known ones are probably formaldehyde, but there are also various volatile gases such as benzene, ammonia, and TVOC that are harmful to human health. The odors and hazards of various harmful gases vary, and there are also some long-standing misunderstandings.
Firstly, let's talk about formaldehyde. The biggest misunderstanding people have about formaldehyde is its odor. In fact, strictly speaking, formaldehyde is colorless and odorless, but if its concentration exceeds 3-4 times the standard, the human body will feel irritating. But in reality, this is not the smell felt by the sense of smell, but the direct burning and stimulation of formaldehyde on the nasal and oral mucosal tissues of the human body. For example, spicy taste is not just a taste, but a burning and painful sensation produced by the mouth. When the indoor formaldehyde concentration reaches a certain level, people will experience symptoms such as sore throat, inability to open their eyes, coughing and sneezing. Formaldehyde gas entering the bloodstream through the lungs can cause great harm to health.
Benzene based harmful gases include benzene, toluene, xylene, etc. Benzene has a strong aromatic odor and is a toxic organic substance that is volatile, flammable, insoluble in water, and soluble in organic solvents such as ethanol. The taste of benzene is similar to the aroma of bitter almonds, making it a "fragrance killer". Benzene is mainly an organic solvent used for paint, including many solvents for perfume and essence.
TVOC is a general term for organic compounds, including benzene, alkanes, aromatics, olefins, halogenated hydrocarbons, esters, aldehydes, ketones, and other organic compounds. In the field of interior decoration, aldehydes and benzene are generally separately mentioned because they pose the greatest harm, while others are collectively referred to as TVOC. There are both colorless and odorless substances in TVOC, so it is impossible to determine the concentration of TVOC without individual testing. However, the methods that can effectively treat formaldehyde and benzene are also effective for TVOC.
The smell of ammonia, commonly known as "Amonia odor," is actually similar to the smell of public toilets, with strong irritancy and a foul odor. The function of ammonia is mainly used as an antifreeze in cement and as an insulation layer on the exterior of buildings, so it is easy to find ammonia exceeding the standard during indoor air quality testing in buildings in the north.
Jason Gypsum Board, as a research and development gypsum board production enterprise, has collaborated with a team of new materials research experts from Zhejiang University of Technology to jointly develop the world's first nano active manganese formaldehyde purification gypsum board - Sen · Long acting formaldehyde purification red board, which has been officially put into the market. After a long period of human and material investment, repeated experimental verification, and testing by national professional institutions, Sen · Long acting Formaldehyde Purification Red Board can achieve long-term purification of harmful gases such as formaldehyde, benzene, ammonia, and TVOC through nano active manganese catalytic technology, and can maintain a long-term formaldehyde removal rate of 75-80%. It has also obtained international environmental protection system certifications such as EU CE and France A+.
