It is also very important for furniture to detect formaldehyde. Furniture formaldehyde exceeds the standard and is now considered to be the indoor first killer. The release period of poisonous gases in the air is longer and the occupants are less likely to notice when they exceed the standard. When they are four or five times the standard, the occupants can smell the smell. Finding a formal testing agency for formaldehyde testing has become an indispensable procedure for staying in a new home. Following Xiaobian to everyone to look at furniture detection formaldehyde method and test items?
Furniture detection formaldehyde method
Furniture detection formaldehyde method 1,
Formaldehyde detection box: convenient and rapid operation; sensitive detection lower limit; can be on-site operation and other features.
Furniture detection formaldehyde method 2,
The electrochemical analysis method is based on the change of the current (voltammetry), electricity (coulometry), and potential (potentiometry) generated in a chemical reaction and determines the concentration of the analyte in the reaction system for quantitative analysis. It is used for the detection of formaldehyde. There are two kinds of polarography and potentiometry.
Furniture detection formaldehyde method 3,
Spectrophotometry is a qualitative and quantitative analysis method based on the selective absorption of electromagnetic radiation by substances with different molecular structures. It is the most common method for formaldehyde detection in homes, textiles and foods.
Furniture detection formaldehyde method 4,
Chromatography has a strong separation efficiency, is not easily interfered by the color of the sample matrix and reagents, and is sensitive and accurate for the detection of complex samples, and can be directly used for the analysis and detection of formaldehyde in living rooms, textiles, and foods.
Furniture detection formaldehyde method 5,
Sensors for formaldehyde detection methods - Sensors for detection of formaldehyde include electrochemical sensors, optical sensors, and photobiochemical sensors
Furniture detection formaldehyde method 6,
Plant removal method: Chlorophytum, Hibiscus orchid, ivy and so on.
What are the items of furniture testing
1. The product timber should be the same as the tree species or wood name required in the order.
2. The product wood should be dried and the moisture content should be 8%~16%.
3. The material of the front view of the product shall be free of white skin, and the sapwood area content of parts and components in other parts shall not exceed 1/10 of the surface area of ​​the part (the side with width less than 8mm is not counted).
4. The product is facing the surface material, the color difference, wood grain to be basically the same.
5. The internal material of the product can be allowed to be repaired without affecting the phase strength of the product, such as minor cracks, dead segments below 25px, etc. The repair is good and not obvious.
Hardware accessories testing:
(1) whether the shape, material and color are consistent with the requirements of the invoice;
(2) Appearance: No rust, no electroplating, no sharp edges, no dents, no deformation, bumps.
The above is what Xiaobian brings to you is the furniture detection formaldehyde method and what items of furniture testing, the house is best to be vacant for a period of time after the decoration is good, if you do not feel relieved, you can then detect if the furniture formaldehyde is exceeded. You can follow the above method to continue testing, hope you can help everyone, if you want to know other relevant information, please continue to pay attention to this site, more exciting so stay tuned!
