One: How long does it take for wallpaper to dissipate its odor?
Generally, the organic solvents in the wallpaper will evaporate within one to two months, primarily depending on the inherent material of the PVC wallpaper.
1、We can analyze this from the perspective of the inks and solvents used in the production of wallpaper. Generally, PVC wallpaper production involves applying ink solutions to the fabric, which inevitably releases VOCs and paper-related odors. Additionally, PVC itself also emits small organic molecules, resulting in a noticeable odor.
2. Considering the material of the wallpaper itself, PVC wallpaper is made of plastic and contains polyvinyl chloride, plasticizers, and chlorine elements. Therefore, it will inevitably emit the inherent odor of these elements. However, most PVC wallpapers undergo three high-temperature processes (above 90°C) during production, including coating, printing, and pressing, typically at temperatures between 120°C and 210°C. This effectively volatilizes most chemical elements during the production process. After installation, only a short waiting period is required.
3. It is normal for PVC wallpaper to have a slight odor, but if the odor persists for a long time and is very strong, it requires attention. Good PVC wallpaper will typically emit a slight odor, but this odor usually dissipates over time. If the purchased wallpaper emits a strong, pungent odor for an extended period, it is recommended to verify with the seller to ensure that the wallpaper meets the required quality standards for health reasons.
Two. Does wallpaper with a smell pose a health hazard?
1、The odor from wallpaper may be caused by issues with the varnish.
Applying a primer to the wall surface before wallpapering is a common practice. Typically, a primer is applied after applying putty powder to the wall, creating a protective layer. If the wallpaper in your home has an odor, it could be due to the poor quality of the primer, which may release harmful substances.
2、The odor from wallpaper may indicate a problem with the wallpaper itself.
Wallpaper that does not meet quality standards, when processed, contains many harmful chemicals that can cause unpleasant odors. Furthermore, some wallpapers emit odors slowly, which can lead to lingering odors even after prolonged use.
3、If the wallpaper has a smell, it may be due to a problem with the additives.
The auxiliary materials for wallpaper primarily include adhesives and wallpaper itself. Almost all adhesives contain harmful substances like formaldehyde. Inferior-quality adhesives contain a higher concentration of these substances, resulting in a stronger odor.
