Five factors affecting the formaldehyde emission of furniture

        Decoration method

The sealing effect of formaldehyde on the furniture surface is obvious. In the specific implementation process, we should pay attention to the selection of low formaldehyde release adhesives, various decorative materials and coatings, and reasonable processes to ensure that no new formaldehyde is released after decoration.

Load factor

The so-called load factor refers to the ratio of the surface area of ​​indoor furniture exposed to air to the indoor volume. The greater the loading rate, the higher the formaldehyde concentration. Therefore, when the functions are basically satisfied, the number of pieces of furniture in the indoor space should be reduced as much as possible, thereby reducing the emission of formaldehyde in the furniture.

Diffusion paths <br> <br> It is worth emphasizing the importance of furniture Edge. When designing furniture, thin plates can be used as much as possible while satisfying the strength and structure.

Environment <br> <br> environment has a great influence on the furniture formaldehyde emissions. Temperature, humidity and ventilation all affect the emission of formaldehyde. Under normal climatic conditions, when the temperature increases by 8 ° C, the concentration of formaldehyde in the air will double; the humidity will increase by 12%, and the amount of formaldehyde released will increase by about 15%. Therefore, under the premise of conditions, air conditioners and fresh air system devices can be used to adjust the indoor temperature and humidity and the amount of fresh air, so that the formaldehyde emission can be properly controlled.

Assembly time and conditions <br> <br> formaldehyde emissions furniture assembly time after the production was proportional to the concentration of, prior to use for some time should landscapes, and placed in a hot and humid environment landscapes, the acceleration formaldehyde emissions, in order to reduce future Pollution in use.

Graphite Powder soft, dark gray; greasy feeling, can contaminate the paper. Hardness of 1 to 2, along the vertical direction with the increase in the hardness of the hardness can be increased to 3 to 5. Specific gravity of 1.9 to 2.3. In the isolated oxygen conditions, the melting point of more than 3000 ℃, is one of the most resistant minerals. At room temperature, the chemical properties of Graphite powder is relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents; materials with high temperature conductive properties, do refractory materials, conductive materials, wear-resistant lubricating materials.


Graphite powder is widely used, according to its different use, we can be divided into the following categories of graphite powder


1. Scale graphite powder

Flake Graphite powder is the most widely used, but also processed into other graphite powder of the original material, scaly graphite powder specifications from 32 to -12000 mesh range, scaly graphite powder toughness is good, with good thermal conductivity and corrosion resistance, can be used as refractory Materials, wear-resistant lubricating materials, conductive materials, casting, Fansha, die and high temperature metallurgical materials

2. Colloidal Graphite powder

Colloidal graphite is formed by the average dispersion of graphite particles below 2u meters in an organic solvent. Colloidal graphite is a viscous suspension of black filaments. Colloidal graphite powder with high quality Natural Flake Graphite performance, in high temperature conditions with special oxidation resistance, self-lubricating and plasticity, at the same time with good conductivity, thermal conductivity and adhesion, mainly used in sealing, metallurgical stripping and other industries

3. Ultrafine graphite powder

Ultrafine graphite powder specifications are generally between 8000 mesh -10000 mesh, mainly used in powder metallurgy release agent, the production of graphite crucible, the battery anode and make conductive materials additives

4, Nano-Graphite Powder

Nano-graphite powder main specifications for the D30 50 100 400 nm, nano-graphite powder process is more complex, low production rate, so relatively high prices, mainly used in anti-corrosion coatings, lubricants additives, grease additives, precision graphite seal And other industries, in addition, nano-graphite powder in scientific research institutions also has a high application value

5, High Purity Graphite powder
