Overview

Many people carefully choose eco-friendly furniture when decorating and purchasing household building materials, but indoor pollution is still very common. What are the reasons. The main reason is that there are defects in the furniture inspection standards. Except for extremely expensive wooden furniture, other artificial furniture inevitably uses adhesives, paints, and other materials in its production and processing. These materials not only release formaldehyde, but may also contain harmful substances such as benzene, toluene, and xylene, which are a serious health hazard

Product Details

Climate chamber method formaldehyde VOC detection environmental chamberThe development principle:
One of the sources of formaldehyde is the glass glue used in indoor decoration, which is frequently used in home decoration. This is a very important decorative accessory. Glass doors and windows, bathroom cabinets, and various dining table decorations are mostly made of glass glue. We use white cement and glass glue to make our construction simpler, but the large amount of formaldehyde gas in the glass glue cannot be ignored. If we use glass glue at home, we can choose high-quality glass, which can fundamentally reduce the release of formaldehyde. Of course, the fundamental method is for each manufacturer to strictly test the formaldehyde emission during the manufacturing of glass adhesive, eliminate products with unqualified formaldehyde emission, and when it comes to formaldehyde detection, we have to mention the formaldehyde emission testing chamber.

Many people carefully choose eco-friendly furniture when decorating and purchasing household building materials, but indoor pollution is still common. What are the reasons. The main reason is that there are defects in the furniture inspection standards. Except for extremely expensive wooden furniture, other artificial furniture inevitably uses materials such as adhesives and paints during its production and processing. These materials not only release formaldehyde, but may also contain harmful substances such as benzene, toluene, xylene, etc. These harmful substances are a serious health hazard. So how can we effectively prevent these harmful substances from harming us, and what should we choose when choosing furniture.
