In recent years, with the continuous development of the home improvement market, problems in various home furnishings have followed. In particular, the harm of indoor environmental pollution to the human body has attracted more and more attention. One of the important sources of indoor environmental pollution, VOC, has gradually surfaced.

VOC (Volatile Organic Compound) is an abbreviation for English Volatile Organic Compounds. VOC is a kind of pollutant in indoor air. Because there are many kinds of VOCs found in indoor air, there are many different concentrations from dozens to one or two hundred kinds. Generally, TVOC (Total Volatile Organic Compounds) has a total volatility. The organic concentration) indicates the total amount. Common VOC types are generally toluene, xylene, p-dichlorobenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde, halogenated olefins (trichloroethylene, dichloroethylene) and the like.

Studies have shown that even if the content of individual VOC in indoor air is lower than its limit, the presence and interaction of various VOCs increases the damage intensity. VOC shows toxicity and irritation. It can cause imbalance of immune level and affect central nervous system function. It can cause dizziness, headache, lethargy, weakness, chest tightness and other symptoms in a short time. It may also affect the digestive system, loss of appetite, nausea, etc. Long-term high concentration environment may also damage the liver and hematopoietic system, causing pulmonary edema and even death.

 With the strengthening of environmental awareness in modern society, all major countries in the world have regulated the VOC substances in regulations.

EU Directive 1999/13/EC restricts certain activities and equipment used in the installation of organic solvents VOC volatile organic compounds

The EU Directive 2004/42/EC restricts the emission of VOC volatile organic compounds from organic solvents used in paints, indoors and interior trim, and the total volatile organic content in indoor air must be less than 300 μg/m3.

The limitation of VOC volatile organic compounds in the US 65 proposal is that the total volatile VOC organic content in indoor air is less than 0.5 mg/m3.

Japan requires total volatile VOC organic content in indoor air to be less than 400μg/m3

China requires that the total volatile VOC organic content in indoor air is less than 0.60mg/m3 (8 hours)

According to the current national laws and regulations on the VOC content requirements, Jinan Naite Technology Co., Ltd. can provide professional VOC detectors to help you control the VOC in the product does not harm the health of consumers.

The sum of VOC volatile organic compounds is an indicator covering almost all the content of harmful volatiles, and it has naturally become an important environmental protection indicator for building materials. In some inspection reports of building materials such as paints and coatings, VOCs are ranked. The first must-test indicator, and the level of VOC directly determines the environmental protection level of furniture and building materials. Ultra-low VOC and even zero VOC are increasingly becoming the environmental indicators jointly pursued by customers and businesses, and research on new products that reduce VOC content must Will become the focus of research and development of various enterprises.
