The concept of removing formaldehyde and its harm are introduced

Formaldehyde (chemical formula HCHO, molecular weight: 30.03, is a colorless, has a strong pungent smell of the gas. Soluble in water, alcohol ether. At room temperature it is a gas, usually in the form of an aqueous solution. 40% of its aqueous solution is called formalin, which has a boiling point of 19℃. Therefore, it is highly volatile at room temperature, and the evaporation speed is accelerated with the rise of temperature.

Sources of formaldehyde

The formaldehyde inside comes from all kinds of man-made plank more (big core board, 9 centimetre board, medium density board), coating and paint also contain certain formaldehyde, but content is lower. Because this is aimed at formaldehyde, deal with all sorts of man-made plank commonly or furniture. The method that solves formaldehyde to release too much is: reduce the usage amount of big core board and other man-made board; Try to buy environmentally friendly artificial plate; After the board into the use of formaldehyde scavenger no. 1 brush plate, and then the plate processing.

Symptoms of formaldehyde poisoning

As a highly toxic substance, formaldehyde ranks second in the list of priority control of toxic chemicals in China. It has been identified by the world health organization as a carcinogenic and malformed substance, a recognized allergen and one of the potential strong mutants.

Research shows that formaldehyde has strong carcinogenic and carcinogenic effects. A large number of literatures have documented that the effects of formaldehyde poisoning on human health are mainly manifested in olfactory abnormality, irritation, allergy, abnormal lung function, abnormal liver function and abnormal immune function.

When the concentration reaches 0.06-0.07mg/m3 per cubic meter of air, children will suffer from mild asthma. When the indoor air reaches 0.1mg/m3, there will be odor and discomfort. Reach 0.5mg/m3, can stimulate the eyes, cause tears; Up to 0.6 mg/m3, can cause throat discomfort or pain. Higher concentrations can cause nausea and vomiting, cough chest tightness, asthma and even pulmonary edema; At 30 mg/m3, it kills immediately.

Long-term exposure to low doses of formaldehyde hazards are: cause chronic respiratory disease, caused by nasopharyngeal carcinoma, colon cancer, brain tumor, menstrual disorders, the nucleus gene mutations, even on single DNA stated and DNA and protein LianJi inhibit DNA damage repair, pregnancy complications, neonatal chromosome abnormality, leukemia, their memory and mental decline.

In all contacts, children and pregnant women are particularly sensitive to formaldehyde, which is a major contaminant in decoration and furniture. Its release period is as long as 3-15 years, when heat and tide meet, it will volatilize from the deep layer of the material, seriously pollute the environment, has become a difficult problem to solve the world, the elderly, children and pregnant women the greatest harm.

Harm of formaldehyde

The place that formaldehyde harms seriously: the bedroom that decorates newly, office, conference room, guesthouse, KTV bag room and furniture bazaar, building materials bazaar.

The following points should be paid attention to to prevent the harm of formaldehyde:

1. Pay attention to the detection and purification of indoor air. According to the degree of formaldehyde pollution in indoor air, ask relevant experts to provide effective treatment program, especially in the home with the elderly, children and allergic constitution of the family, more to pay attention to.

2, the wardrobe that makes with man-made board, if formaldehyde is not cleared clean, must notice when use, do not put underwear, nightgown and children's clothing inside as far as possible.

3, take a few effective purify measure inside indoor and furniture, can reduce the harmful gas that furniture releases.

The manifestation of formaldehyde poisoning

Acute formaldehyde poisoning is a systemic disease caused by exposure to high concentration of formaldehyde vapor, mainly damage to the eye and respiratory system.
