When decorating a new house, everyone knows that formaldehyde needs to be removed, but is the smell after decoration always formaldehyde? In fact, formaldehyde and TVOC are both important sources of indoor air pollution.
Formaldehyde is a colorless gas with a pungent odor, mainly derived from building materials such as adhesives and paints. It has a serious impact on human health. Spaces with excessive formaldehyde levels can cause dry eyes, tearing, dry throat, coughing, and even threaten life and cause cancer.
TVOC is an abbreviation for "Total Volatile Organic Compounds." Its sources are extremely widespread; paints, varnishes, adhesives, furniture, carpets, and wallpaper in the home can all be sources of TVOC. It is toxic, irritating, and carcinogenic to the human body, affecting the central nervous system and digestive system, and in severe cases, may damage the liver and hematopoietic system.
01. Regarding formaldehyde and TVOC
Six-dimensional antibacterial graphene ecological board
For formaldehyde and TVOC issues, prevention is more important than post-treatment. The best approach is to control the quality of materials during the initial selection process. Recognizing this need, Qiannianzhou has upgraded its "Zinc-Efficient Antibacterial Graphene Ecological Board" product, launching the "Six-Dimensional Antibacterial Graphene Ecological Board." This new board adds "formaldehyde removal and TVOC elimination" to its existing "dual antibacterial and one-prevention" features. By adopting scientific and effective measures, indoor formaldehyde and TVOC concentrations can be reduced, creating a healthy and comfortable living environment.
02. Regarding the cleaning and removal
Yi Jing: Formaldehyde purification efficiency ≥80%
A specialized formaldehyde-removing material containing a large amount of amino groups is added during the paper impregnation process. This material exhibits strong reactivity, reacting with formaldehyde at the C-6 position, making it difficult for adsorbed formaldehyde molecules to be released again. Through amino adsorption, a zinc-based catalyst reacts with H₂O and CO₂ in the air, generating electron-hole pairs and active oxygen, decomposing the adsorbed formaldehyde into H₂O and CO₂, thus completely solving the secondary pollution problem caused by saturation of the adsorption material. The formaldehyde purification efficiency is ≥80% in 24 hours, far exceeding the industry standard JC/T 2761-2023's requirement of ≥55% purification efficiency.
Second division: TVOC removal rate ≥ 60%
A specialized TVOC removal material containing a large amount of amino groups is added during the paper impregnation process. This material exhibits strong reactivity, reacting with TVOCs at the C-8 position, making it difficult for adsorbed VOC molecules to be released again. At room temperature, a zinc-based catalyst reacts with oxygen and water in the air under light and room temperature conditions, generating electron-hole pairs and reactive oxygen species, oxidizing the bound VOCs into corresponding organic acids. This not only effectively increases the adsorption capacity for harmful substances but also completely solves the problem of secondary pollution caused by saturation of the adsorption material. According to the QB/T 2761-2006 method, the TVOC removal rate after 24 hours is ≥60%.
In the field of graphene technology, Qiannianzhou continues to explore and is committed to driving industry innovation through technological power. The comprehensive upgrade and launch of the six-dimensional antibacterial graphene ecological board is another important achievement of Qiannianzhou in related fields, providing stronger protection for the health of the home environment.
