Indoor Formaldehyde source and Pollution Control

Indoor Formaldehyde Source
Formaldehyde mainly comes from building materials, furniture, various Adhesive Coatings, synthetic fabrics and indoor
Source.
Wood-based Panel. Because of its strong adhesion and enhanced board hardness, insect resistance, anti-corrosion function and price
It is cheap, so it is the first choice for interior decoration of plywood, blockboards, MDF, and particleboard raw materials.
Material-urea-formaldehyde resin with formaldehyde as the main ingredient. Urea-formaldehyde resin can also be used as heat preservation and insulation materials in buildings. Board
The residual formaldehyde and formaldehyde not involved in the reaction will be gradually released to the surrounding environment, the maximum release period can reach more than 10 years, is the Formation
The body of formaldehyde in the indoor air.
Carpet and other synthetic fabrics. Adhesive and wall cloth, wallpaper, foam and other indoor decorative materials in the carpet
The raw material emits formaldehyde.
The formaldehyde released from synthetic fabrics cannot be ignored in the indoor environment. To improve the properties of synthetic fibers
Yes. It is generally used to organize resin with formaldehyde resin. Therefore, after finishing the fabric, a small amount
Resin Finishing Agent not involved in the reaction. These resin fiber fabrics are released during use and storage.
Travel away from formaldehyde.
Incomplete combustion of fuel and tobacco leaves and the release of books.
In addition, cigarette smoke contains Formaldehyde
The use of cosmetics, detergents, pesticides, and preservatives can release formaldehyde.

Wood-based Panel Furniture, some manufacturers in order to pursue profit, the use of unqualified sheet, IN THE BONDING
Practical Manual for indoor pollution detection and control methods and standards
Poor glue is used when surface materials are used. In addition, the manufacturing process is not standard. As a result, the customer buys them home and buys them back.
Small exhaust stations.
Some formaldehyde materials, such as cigarettes and some organic materials, are emitted after combustion.

2. hazards of formaldehyde to human health
Formaldehyde is irritating to human eyes, noses and respiratory tract.

The effects of low concentrations of formaldehyde on human body are mainly manifested in skin allergies, cough, and many
Phlegm, insomnia, nausea, and headache. People who have just been living in the room where they use particle boards as floor are disgusted with smells, headaches, and heads.
Dizzy and cough response.

3. formaldehyde pollution control
Low Formaldehyde Content and formaldehyde-free decoration materials are used for interior decoration,
Circle member
Article 1 major pollutants in the indoor environment
High-quality health and environmental protection building materials.
The sawing port of wood-based panel should be coated with paint to make it fully cured, which can form a stable protective layer,
To prevent the formaldehyde in the sheet from being emitted.
The sawing port of wood-based panel should be coated with paint to make it fully cured, which can form a stable protective layer,
To prevent the formaldehyde in the sheet from being emitted.
Should not be checked in immediately after the decoration, should open windows, ventilation to let indoor air pollution, usually said several Decoration
The indoor formaldehyde concentration can be reduced to meet the indoor standard.
Release of formaldehyde in interior decoration materials, indoor temperature, humidity, ventilation, and years of use,
Loading degree, that is, the surface area of the materials in which formaldehyde can be dispersed in the indoor space. high temperature, high humidity, and negative pressure will accelerate
The distribution of formaldehyde is enhanced, and the ventilation frequency is favorable for the distribution and discharge of formaldehyde.
Indoor greening: indoor planting of plants such as chlorpyrifos and Aloe Vera will reduce the concentration of harmful gases in the room.
