In recent years, the home and building materials industry such as flooring frequently exposed problems such as excessive formaldehyde content, which has led many consumers to choose to remove formaldehyde from the formaldehyde company after the home decoration is completed. Formaldehyde is carcinogenic and has long been living in an environment with excessive formaldehyde. The probability of leukemia is increased by many times. More and more people in Hefei choose to remove formaldehyde from formaldehyde. Due to the late start of China's indoor air treatment industry, the lack of standards has led to chaos in the industry.
At present, there is still a lack of corresponding regulatory system for this industry, which has led to a mixed market, and many companies have not necessarily been reliable in removing formaldehyde. At present, only the "Code for Indoor Environmental Pollution Control of Civil Building Engineering" and "Indoor Air Quality Standards" are available. These two standards can be referred to. It is worth noting that the current indoor environmental testing market is very confusing, and the test results of many unqualified testing organizations often do not match the actual situation.
At present, the main technology of formaldehyde removal in the international community is photocatalyst, photocatalyst, formaldehyde scavenging and other products. In today's network and market, various brands can be found, but the prices and quality of these products vary widely. In addition to photocatalysts, there are many other formaldehyde-removing products on the market. Due to lack of industry standards and supervision, these products often decompose other substances harmful to the human body while reacting with formaldehyde.
Since the beginning of this year, new standards for the home industry have been introduced, and many old standards have been revised and implemented. The industry knows that the introduction of new standards means that the home industry will change, and at the same time, it will eliminate a number of home enterprises that cannot be transformed and upgraded. In fact, this will help to purify the home market and promote the healthy development of the industry.
Standard 1, the formaldehyde emission limit of the plate is more strict
The "Formaldehyde Release Limits for Interior Decoration Materials, Wood-based Panels and Their Products", which was implemented on January 1, 2002, stipulates the test method for the formaldehyde release limit value of different product types, and divides the product into E1 according to the release amount of formaldehyde. E2 two levels. As consumers pay more and more attention to the health and environmental protection of homes, the formaldehyde emission of household products on the market is less than 0.5mg/L, which has prompted the revision and upgrading of this standard. Recently, it was learned that the revised standard has now entered the approval stage. At the same time, Duan Xinfang, secretary general of the National Standardization Technical Committee for Wood-based Panels, said that the formaldehyde emission limit value requirement in the new standard will definitely increase.
Standard 2, the air purifier function will be subdivided
It is reported that the current standard of air purifiers was implemented on September 1, 2009. The new version of the standard is being revised and is expected to be released next year. The new standard not only improves the technical indicators and refinement test methods for different pollutants, but also judges the purification performance of the products more rigorously and scientifically, especially for the purification of PM2.5 and formaldehyde removal functions. Detailed experimental method. Industry insiders pointed out that the over-promotion of the air purifier function on the market will be curbed.
Standard 3, furniture non-destructive testing method is popular
It is understood that in the current standard, the test furniture is usually measured by the "dryer" method, and the furniture is cut into small pieces for testing, but in the "Restriction of Hazardous Substances in Wood Furniture for Interior Decoration Materials", the revision of the draft for comments The climate chamber method is used to evaluate the furniture by placing the furniture in a climate chamber and detecting the air quality of the climate chamber under simulated conditions.
Standard 4, the most stringent national standard for faucets will be implemented
From December 1 this year, the new national standard "ceramic sealing faucets" will be officially implemented. The new national standard has also been supplemented in many aspects such as water-saving performance and quality of use of faucets. Among them, the new standard limits the amount of metal contaminants released from the nozzle, and limits the requirements for 17 kinds of metal precipitates such as lead, antimony, arsenic and antimony.
Standard five, soft bed sofa can be tested without damage
The author has learned from the insiders that the limited regulations on harmful substances such as formaldehyde and TVOC for sofas and mattress products, "Limits of harmful substances in soft furniture sofas" and "Limits of harmful substances in mattresses for soft furniture" have been drafted and are currently waiting. Announced after the review. These two standards stipulate the limits of hazardous substances and stipulate the test methods. After the implementation of the standards, sofas and mattresses are expected to achieve non-destructive testing.
In October 2014, the Beijing Municipal Bureau of Quality and Technical Supervision posted a draft for the “Emission Standards for Air Pollutants in the Wood Furniture Manufacturing Industry†to make specific requirements for the discharge of wooden furniture. At present, the opinion draft is in the publicity stage, and the furniture company can reflect the opinion, and the deadline is until October 29.
At present, the "Air Pollutant Emission Standard for Wood Furniture Manufacturing Industry" at the stage of collecting opinions is a Beijing local standard drafted by the Beijing Municipal Environmental Protection Research Institute. It is mainly aimed at the environmental pollution problem of wooden furniture manufacturing industry, namely this year. The “world's most stringent†environmental emission standards related to furniture manufacturing were exposed in the month. In addition to the limits of air pollution emission concentration, testing and control requirements in the production process of the wood furniture manufacturing industry, the standard also produces the nature of the paint in the household production process, the production environment, the production process and equipment in the production process. The process has also been detailed.
Compared with the previous DB11/501-2007 "Integrated Emission Standards for Air Pollutants" implemented by the furniture industry, the new standard significantly reduces the maximum allowable emission limits for benzene, benzene, non-methane total hydrocarbons, and particulate matter. Wood processing workshops, painting and polishing workshops, and plant boundaries also specify emission concentration limit values ​​for pollutants such as unorganized particulate matter and VOCs. The draft also has detailed regulations on the height of the exhaust pipe and the discharge of pollutants. The opinion draft also requires: “The container containing the VOCs material must be a sealed container; the use and operation of the organic solvent should be carried out in a closable operating environment or equipment; the paint mixing workshop, drying workshop or drying room should be installed. Closed exhaust system and piping to ensure that VOCs with unstructured fugitive emissions are introduced into the pollution control equipment."
