What is the composition of the standard gas of the VOC monitor in the paint industry?

The national standard stipulates that the VOC content in each liter of paint and paint shall not exceed 200 grams.

Volatile organic compound, the abbreviation of the first letter of the three words, abbreviated as vocs. Total volatile organic compounds are also sometimes referred to as TVOC.

According to the definition of the World Health Organization, if the boiling point of the compound is 50 -250 at air pressure, it is a volatile organic compound. They will exist as a gas at room temperature. According to its chemical structure, it can be further divided into eight categories:

Alkanes, aromatics, alkenes, halogenated hydrocarbons, esters, aldehydes, ketones and others. The main components of VOCs are: hydrocarbons, halogenated hydrocarbons, oxycarbons and nitrogen hydrocarbons, which include:

Benzene series, organochlorides, Freon series, organic ketones, amines, alcohols, ethers, esters, acids and petroleum hydrocarbon compounds, etc.

Outdoors, VOCs mainly come from fuel combustion and transportation: while indoors they mainly come from combustion products such as coal and natural gas, smoke from smoking, heating and cooking, etc., emissions from building and decoration materials, furniture, household appliances, detergents and the human body itself.

The composition of the standard gas of its industry monitoring instruments. If you go to the industry, the composition of the monitoring instrument is based on the function and characteristics of the instrument mark. See if he goes over the bar.

"VOCs" is the abbreviation of volatile organic compounds, which exist in the air in the form of evaporation at room temperature, which has a certain impact on the environment, because benzene and benzene series are the main components of VOCs, so they are harmful to the human body. VOC content is an important indicator in the safety testing process of coating products.

VOC content must be 200 g liters.

The environmental labeling certification standard also requires that the VOC content of wall paint after water removal should be 80 grams of liters; The standards in developed countries are more stringent, such as the EU standard for wall paints to have a VOC content of 75 grams of liters.

VOCs in living rooms are mainly used in latex paint, wallpaper, floors, thermal insulation materials, adhesives and other decoration materials. In view of the high volatility of VOCs, while choosing high-quality wall paints with low VOC content, the newly renovated houses should be left vacant for a period of time to maintain ventilation to reduce the residual amount of VOCs in the air.

VOC is the English abbreviation of volatile organic compounds, commonly known as the chemicals that are harmful to the human body in latex paint (heavy gold.

genus) refers to VOCs. When VOC reaches a certain concentration in the air in the room, people will start to feel headaches and nausea.

weakness of heart and limbs; If you continue to stay for a long time, it will damage the liver, kidneys, brain and nervous system, and may even cause convulsions.

Convulsions, coma, and memory loss, with serious consequences.

VOCs are so harmful, but where does it come from? Experts pointed out that building materials such as walls, ceilings, and floors, as well as decorative materials such as latex paint, wallpaper, thermal insulation, and adhesives are the main VOCs.

It should be pointed out that the VOC of latex paint, which is most commonly used in decoration, mainly comes from the VOC of raw materials, package.

Including formaldehyde, ammonia, ethylene glycol, etc., so it is very important to control the VOC content of raw materials! VOC contains on interior wall latex paint.

The amount of harmful substances in the national "interior decoration materials" stipulates that it should not exceed 200 grams of liters; "Environmental Label Certification.

"Quasi" also requires 100 grams of liters; The standards of developed countries are more stringent, and the VOC of matte latex paint in the EU standard contains.

The amount should be 75 grams of liters.

The comparison of interior wall paint is the VOC (harmful substance) content, and the lower the VOC, the more environmentally friendly.

VOCs are volatile organic compounds

compounds). VOC in the ordinary sense is the command of organic matter; However, the definition in the sense of environmental protection refers to a lively class of volatile organic compounds, that is, the type of volatile organic compounds that will cause harm.

In the decoration, the general nail aldehyde, benzene, ammonia and other harmful organic matter gas particles, paint will basically release the above substances, so the reason why the decorated house can not be moved in immediately is this, it is necessary to effectively purify the indoor air.

VOCs are volatile organic compounds.

Some VOCs are hazardous chemicals and should be protected.

Environmental protection paint refers to the whole coefficient standard of the coating, including formaldehyde content, VOC content, etc., which are within the range of national standards, or even lower.

VOC refers to a volatile organic compound that, if the amount is too high, it is harmful to the human body.

The real environmentally friendly paint is after brushing and ventilation, and will not produce too high harmful substances to affect the human body.

The truly eco-friendly type is water-based paint. But comparatively speaking, oil-based paint is less environmentally friendly than water-based paint. Functionally speaking, oil-based paint is a little easier to brush. Water-based paint is now vigorously promoted by the state.

v ) Well, jubilant paint is mainly ** furniture paint wood paint, of course, there are also interior and exterior wall latex paint. Water-based paints and oil-based paints are available.

Our main concern is the VOC content, so the following methods can be employed: open the latex paint and smell it, the smaller the taste, the better, and a good latex paint, the VOC is lower, so the smell is small. Good environmentally friendly paint brands such as Nippon, Dulux, Red Apple Paint, and Carberry can be selected as a reference.

Now several big brands of paint on the market are almost environmentally friendly paints.

If you want to paint environmentally friendly, you should try to choose a big brand, which will be more popular.

VOC refers to the amount of volatile organic compounds (thinners) in paints!!

The current standard is that the VOC content in the construction state is 420 and is exempt from GST!!
