언제 그것 오기 to 포름알데히드, everyone is familiar with it. We often deal with it in our daily lives. 포름알데히드, as a common indoor environmental pollutant, not only has a pungent odor, but also has toxicity, which can cause 알레르기 dermatitis, fatigue, insomnia, headache, and also harm the respiratory tract and lungs, cardiovascular system, liver, etc., and seriously cause life da

그리고 여름 할 수 있다 be said to be the golden period for 포름알데히드 제거, why?

To clarify this issue, let's first understand the physicochemical properties of formaldehyde. Formaldehyde, chemical formula HCHO, formula 30.03, also known as formic aldehyde. Colorless gas with a special pungent odor and irritating effects on the eyes, nose, etc. The relative density of the gas is 1.067 (air=1), and the liquid density is 0.815g/cm ³ (20 degree ). Melting point 92 degree , boiling point -19.5 degree . Easily soluble in water and ethanol.  농도 의 수성 용액 캔 도달 위로 to 55%, 보통 40%, called 포름알데히드 물, commonly known as formalin (포르말린), is a colorless liquid with a stimulating odor.

그's right, it's the boiling point! When it comes to boiling point, everyone is familiar with it. Baidu: Boiling is a violent vaporization phenomenon that occur simultaneously inside and on the surface of a liquid at a certain temperature. The temperature at which a liquid boils is called the boiling point.

휘발 참조 to a 물리적 변화 in which a 액체 변화 into a 가스 및 스프레드 주변 아래 그것 끓는 포인트. That is to say, the volatilization point of formaldehyde is 19 degree , which is the key to finding the problem. 포름알데히드 in 장식 재료 탈출 바깥쪽 through 휘발. 19 degree , 19 degree , it's terrible! Say important things three times.

그것 회전 출력 그 언제 포름알데히드 is 위 19 도 , its release begins to increase, and when it exceeds 30 degree , it begins to grow exponentially. 포름알데히드 stops volatilizing when it is below 10 degree , which is why many people are puzzled. 언제 그들 떠나기 the windows open 24 hours a day in winter, the smell is still strong when they check in. This is because the 실내 온도 is too low, and formaldehyde does not volatilize at all. As soon as they check in, close the windows, and the temperature rises, formaldehyde begins to volatilize, volatilizing fiercely, just like yesterday when the decoration was just completed.

Why is there a completely different contrast? Let's first analyze the mechanism of indoor air pollution and perhaps solve this mystery. Summer is the most rampant season for formaldehyde volatilization. If the room temperature rises by 1 degree , the concentration of formaldehyde in the indoor air will increase by 0.15 to 0.37 times. When the temperature rises to 34 degree and the relative humidity is 50%, the formaldehyde release concentration in the air is 5.53 times higher than usual in rooms that have undergone indoor decoration or purchased new furniture within a year.
