Wood furniture and composite wood flooring may release formaldehyde, and consumers should pay special attention to smells for a long time. ·Company must have: Air Purification Qualification Certificate ·Persons must have: professional certificate for indoor air testing · Equipment must have: Qualifications approved by the Technical Supervision Bureau Miss Chen: Recently, the inspection data released by the Guangdong Provincial Quality Supervision Bureau showed that a quarter of the wooden furniture formaldehyde emission exceeded the standard. I have renovated the house for several years, but the wardrobe always has an odor. This year, especially since the summer, I am Worried that formaldehyde exceeds the standard affects health, do I really want to throw away the wardrobe? Is there any other way to detect excessive conditions and manage? Indoor decoration pollution has always been a "stubborn disease" for the public, and an important source of pollution is formaldehyde. Sandwich panels, MDF, blockboard, plywood, laminate flooring, paint and furniture used in interior decoration may contain high concentrations of formaldehyde, and summer is the “peak season†for formaldehyde volatilization. For the case of excessive formaldehyde, the public can pass the self-inspection or ask the professional company to detect, and the professional company can help in the governance. There are formaldehyde detection reagents available on the market. During the test, it is most suitable to maintain the indoor temperature at 20 degrees of ingestion. After 2 to 3 hours of blocking, the formaldehyde concentration is determined by comparison with formaldehyde chromatography. The concentration is greater than 0.8mg/m3, which is lower than the national first-class residential standard, which is excessive formaldehyde. Choice: Key to qualification Environmental protection companies have emerged in an endless stream, and one practitioner revealed that there are many drowning in it. It is understood that to select a regular one among many companies, the company qualification certification is the key. Generally speaking, there is a three-party certification. The company needs to obtain the "Air Purification Qualification Certificate" issued by the China Environmental Testing Association. The employees must have the "Certificate of Indoor Air Testing". The company's equipment needs to have the qualifications approved by the Technical Supervision Bureau. When selecting a company, consumers can also query the cases that the company has operated. Generally, the merchants who have done processing work in the large-scale office area have a high degree of trust. In addition to the companies on the market, the Guangzhou Environmental Protection Monitoring Center Station and the Guangzhou Environmental Protection Monitoring Center Station are two authoritative state agencies for air monitoring. Detection: 150 yuan per "point" The reporter consulted many companies in the city who are engaged in home environmental protection. Most of these companies have opened a business to deal with excessive formaldehyde. It is understood that after determining the service, the company will test the governance area and formulate a treatment plan based on the test results. The charging standard is about 100-150 yuan for one inspection point, and the number of detection points is determined by the number of closed spaces in the governance area, that is, one hall of 10 square meters is equivalent to one hall of 100 square meters. According to the company's inspectors, in general, a house of 100 square meters and two rooms and one hall requires three points and costs 450 yuan. Governance: re-examination but free re-do After the test, the formaldehyde concentration is between 1 and 1.5 times or less, and it can be used without professional treatment. Indoor air quality such as ventilation, aloe vera and other indoor plants and active agents such as activated carbon are used to improve indoor air quality. For professional management, the charge is related to both the size of the space and the concentration of formaldehyde in the room. In particular, it is important to note that the cost of cleaning up a home or used office area is more expensive than unused. The reporter learned that the levy on governance costs fluctuated between 9 yuan per square meter and 40 yuan per square meter. In the interview, a company gave its own quotation, with a concentration of 25 yuan within 3 times and a charge of 35 yuan at 4 to 5 times. For residential buildings, a concentration of 2 to 3 times exceeding the standard is a common phenomenon. A citizen who once managed to over-standard formaldehyde in indoor decoration pointed out that for all kinds of quotations, consumers need to open their eyes. When actually signing a contract, the price still has some flexibility. It is understood that the current governance mostly uses photocatalyst technology. The general level of household pollution only needs to be processed once, and after 3 to 7 days, the re-inspection is carried out, the re-inspection is passed, and the treatment contract is completed. In addition to the re-examination of the governance company, the current professional governance institutions in Guangzhou allow consumers to ask other institutions to re-examine, that is, they can find the national agency Guangdong Environmental Protection Testing Center or other companies to do the second inspection. Companies that fail to pass the re-examination will pay the re-examination fee to the customer and process it again until it is qualified.
