According to the use of construction, decoration and furniture materials in our country, the country’s random inspection of indoor building materials found that materials with toxic gas pollution accounted for 68%. The interior decoration materials contained more than 300 volatile compounds, of which formaldehyde, benzene and DMF were the main pollutants . The main decoration materials such as artificial board, floor, adhesive, paint, lacquer, synthetic leather, wallpaper, furniture, etc. are all important sources of harmful substances.
According to the types of pollutants and the degree of volatilization, man-made plates belong to the severely hazardous decoration materials. Because the cabinets on the market are more or less mixed with some adhesives, and these adhesives contain a lot of formaldehyde. Even if environmentally friendly plates are used, if there are many cabinets in the home, it is easy to exceed the space carrying capacity, which will cause formaldehyde to exceed the standard.
Artificial board will release formaldehyde for a long time
Artificial board is the most well-known source of formaldehyde emission, mainly including plywood, fine wood board, medium density fiberboard and particle board. No formaldehyde does not form a glue, such boards require the use of adhesives, and the adhesives are aldehyde-containing resins with formaldehyde as the main component, and urea-formaldehyde resins as the main component. Urea-formaldehyde resin is widely used because of its low price and good bonding performance. This situation will not change fundamentally for a long period of time.
When the urea-formaldehyde resin is cured, most of the linear structure resin becomes an infusible and insoluble network structure or body structure, but there are some resins that have not undergone curing reaction inside the board, especially the core layer, and it is easy to decompose formaldehyde and release it. The cured resin will also be hydrolyzed. Under high humidity, high temperature and acidic environment, more formaldehyde will be released by hydrolysis! This is also the reason why wood-based panels will release formaldehyde for a long time.
Because the price of the wallpaper is close to the people and the decoration effect is good, many people now like to choose it as the decoration, but they ignore the potential pollution hazards of the wallpaper. Adhesives are used to bond the wallpaper during the application process, and a large amount of formaldehyde is present in the adhesive.
In addition, the wallpaper itself is actually quite polluting. Due to the need to add some pigments and colorants in its manufacturing process, these also contain many harmful substances. Especially for some non-qualified non-woven fabrics, this kind of material is a synthetic material, and there are many harmful substances inside, so you must pay attention to carefully select when buying.
Paint is also a serious hazardous substance in the decoration materials. Some decoration companies or construction teams will use some poor quality latex paint or gypsum powder for the wall during construction, which often contains a lot of urea-formaldehyde glue.
According to statistics, for a room with a construction area of 100 square meters, only 100 kg of glue will be used for the putty on the wall (not including the glue for the furniture board). If calculated according to national standards, the 100 kg of glue contains 100 g of formaldehyde. This 100 grams of formaldehyde is evenly distributed in a 250 cubic meter room, and it takes 5,000 days to release!
Glue for floor and tile laying
Nowadays, households usually choose to lay the floor or ceramic tiles on the floor of the house. Generally, the owners will carefully check whether the environmental index reaches the standard when selecting the floor and ceramic tiles, but there is no strict control on the construction process.
Floor adhesives are used in the process of paving the floor. This adhesive is mainly used to fix the floor, and it can also prevent the moisture on the floor from eroding the floor and prevent the floor from being deformed due to moisture. Poor-quality floor glue will contain a lot of harmful substances, which will harm the human body.
In the process of laying tiles, tile adhesives will be used. This kind of adhesive is used to make the tiles closely adhere to the floor and wall surface. This kind of adhesive will also produce harmful substances.
In fact, in addition to the pollution of furniture decoration, soft decorations in our rooms are also an important source of pollution. Such as curtains, quilts, carpets and other items, we rarely associate them with pollution of home improvement in our lives, but according to the degree of pollutant volatilization, such textiles are moderately polluted. Because we are in close contact with these things every day, the harmful substances on these items are more likely to harm us.
These textiles will use some dyes and auxiliary chemicals in the production process, which contains a lot of formaldehyde and toxic and harmful chemicals. And if we don’t pay attention to buying some low-quality soft jewelry, not only will we smell a pungent odor, it may even cause us allergies, coughs and other physical discomforts, so we should also pay attention when buying.
Other auxiliary materials
Auxiliary materials such as glass glue, caulk, interface agent, etc., although not used in the decoration, but they contain a lot of formaldehyde. When buying, we should pay attention to select products with big brands and high environmental protection coefficient. If the decoration company provides auxiliary materials, it is necessary to know in advance whether the brand and quality of these auxiliary materials are reliable, and carefully do the acceptance work of the materials.
The toxic and hazardous chemicals in the decoration are everywhere and pervasive. Even if we have environmental awareness and keep a high degree of vigilance, a little carelessness in the decoration process will still allow formaldehyde to take advantage. Eventually, it will inevitably lead to pollution of home decoration, so If you want to completely eliminate pollution from home improvement, you can only control it from the source.
To this end, Huai’an Kaiyue Technology Development Co., Ltd.’s main product is environmentally friendly water-based leather, which is suitable for home improvement soft bags, wall leather and sofa leather. Our water-based leather has zero emission of harmful chemical substances, and the limit of chemical substances is much higher than the EU standards and national standards. It is the most stringent standard at present. Relying on Hyatt standards and China’s first household hazardous chemical testing center, the industry’s first hazardous chemical management and control system has been established to ensure non-toxic products. Achieve 100% detection of raw and auxiliary materials, set up key process control points in the production process, and 100% detection of hazardous chemicals in the whole process of after-sales products in the storage of finished products.
