Nowadays, people's living standards have improved. Many people will buy the best quality flooring during the decoration process, in case they are not good for their health in the future. Everyone about the formaldehyde detection method on the floor should also know about it. It can be used in daily life. If you want to try it after purchasing the floor, then come and learn with Xiaobian. Related content!
First, what are the formaldehyde detection methods for the floor?
One of the methods for detecting formaldehyde on the floor: spectrophotometry, which is a qualitative and quantitative gap method based on molecular structure and based on the absorption of electromagnetic radiation by molecules of different structures. It is the most important three kinds of formaldehyde at present. Conventional testing methods for pollution problems. Modern spectrophotometry mainly includes acetylacetone method, phenol reagent method, AHMT method, magenta-sulfuric acid, chromotropic acid method, phloroglucin method, catalytic photometry, etc. Each method has its own focus, each has its own advantages and disadvantages. Sex.
The second method for detecting formaldehyde in the floor: Electrochemical method, electrochemical method is a method for quantitative analysis of the concentration of the analyte from the change of current, electric quantity and potential generated in the chemical reaction. The current electrochemical methods for detecting formaldehyde mainly include polarographic method and potential method.
The third method of formaldehyde detection on the floor: chromatography, chromatography is a method for detecting food, home and textiles. It is flexible and adaptable. It can be directly used for the analysis and detection of formaldehyde in living room, textiles and food. The formaldehyde in the sample can also be derivatized and then measured. However, the chromatographic operation process is cumbersome, and is generally used when large-scale detection of formaldehyde content.
The fourth method of floor formaldehyde detection: sensors, the sensors here mainly include electrochemical sensors, optical sensors and photobiochemical sensors. Among them, the electrochemical sensor has a simple structure, low cost and short use time. Optical sensors are expensive, bulky, and more restrictive to use. But in general, the price of the sensor is much higher than other methods of detecting the content of formaldehyde, and it is difficult to have their market in the market.
Second, the floor purchase notes
1. Pay attention to the added color floor: With the development of the society, there are a lot of colored floors on the market today. Since the additive floor will be cracked and blasted after being paved, it should refuse to add color to the floor when purchasing.
2, pay attention to the floor notch and thickness: the notch and thickness is the key to the purchase of the floor, the standard thickness of the floor is usually 18mm, the market has many less than this standard thickness, after the use will appear arching, corrugated And so on; if the floor notch is short, it will produce a sound, which will make a buzzing sound when used.
3, pay attention to paint: paint will determine the color, grade, environmental protection and service life of the floor. In many cases, in order to achieve an aesthetic effect, the color is added to the paint.
4, know the name of the floor: no matter what kind of board you buy, you have to let the manufacturer write the name of the floor on the contract and sales list, once you find the name is wrong, then you can double the claim to the manufacturer.
5. Negative package products: There are many floors on the market that have been processed by some small manufacturers. After packaging, they will be used as their own brands. Such manufacturers aim to make money, and they cannot guarantee the quality, such as problems. , push it to the manufacturer, so when buying, be sure to see if there is a factory address on the box, sign the contract, when the deposit is paid, ask his manufacturer's phone to verify the manufacturer.
6, pay attention to after-sales tricks: the installation of after-sales personnel is also the most important link, some of the floors sent by the merchants are partially loaded with shredded wood, which will throw away the shredded wood when you are not paying attention, let you go again buy.
The above content is the detailed steps related to the formaldehyde detection method of the floor. I don't know if you have mastered it. The formaldehyde detection method of the floor has a little understanding of the second and second. It is better to buy the floor later. If you want to know more about the decoration information, please continue to pay attention. Renovation home network!

Butterfly Valve is a kind of valve that uses disc type opening and closing parts to rotate about 90 ° to open, close or regulate medium flow. Butterfly valve is not only simple in structure, small in size, light in weight, low in material consumption, small in installation size, small in driving torque, simple and rapid in operation, but also has good flow regulation function and closing sealing characteristics at the same time. It is one of the fastest developing valve varieties in the past ten years. Butterfly valves are widely used. The variety and quantity of its use is still expanding, and it is developing to high temperature, high pressure, large diameter, high sealing, long life, excellent regulating characteristics, and multi-function of one valve. Its reliability and other performance indexes have reached a high level. Stainless steel butterfly valve material has 304316l, etc., with clip connection, lug connection and flange connection.
