Knowledge 1. How harmful is formaldehyde?
1. What is formaldehyde?
Formaldehyde is a colorless gas with a strong smell and is easily soluble in water, alcohol and ether. Formaldehyde is gaseous at room temperature and usually exists in the form of aqueous solution. 35 ~ 40% aqueous formaldehyde solution is called formalin. It has been identified as carcinogen and carcinogen by the World Health Organization and the World Association for Cancer Research.
2. What are the high risk factors of formaldehyde?
As a high-risk gas, formaldehyde will do harm to our health. The biggest factor is that formaldehyde has three characteristics: easy evaporation (it will evaporate with indoor temperature and humidity), long duration (its duration is 3- 15 years) and wide channels (indoor decoration, various furniture, smoke generated by smoking, etc.). ).
Knowledge 2. How to measure formaldehyde in new houses
One: Choose a third-party measurement company.
Usually you can't directly measure formaldehyde yourself. This invisible and intangible thing can only be measured by some physical and chemical methods. Here are some methods, but if you don't care about these methods or don't understand them at all, you can find a third-party measurement company, and they will issue relevant measurement data.
Two: formaldehyde self-test box
This is a simple self-measurement method. Usually, you can use the self-test box to measure before asking a third-party measurement company to do it. If it is found that formaldehyde may exceed the corresponding score, you can find a third-party company to do a detailed measurement. The self-test box is similar to ph test paper. You can get a formaldehyde score by comparing colors. If the liquid in the test is blue, it is a trace of overspending, so please ask a professional company to measure it as soon as possible. However, the indoor formaldehyde content standard is not higher than 0.08 mg/m3, the error of the self-test box is large, and the measured data is inaccurate, so it can only be used as a reference.
Three: self-experience measurement method
According to my own feelings, for example, when the whole family moves into a new house, everyone will catch a cold, have low immunity, and have a headache and dizziness. Reduce energy and fatigue. When you are near a piece of furniture, if you feel tears in your eyes, feel an influential smell. At this time, it is necessary to make more detailed measurements quickly and insist on smooth indoor ventilation.
Knowledge 3. Small measures for new house in addition to formaldehyde
1, open the window for ventilation to keep the indoor air unblocked.
Always open the window for ventilation, and keep the indoor air unobstructed. If it is a newly renovated new house, often open the window for ventilation, which is conducive to the evaporation of harmful gases such as indoor formaldehyde. Don't smoke at home. If cooking, use a range hood. It is best not to spread carpets in large areas at home to avoid causing allergies. The production cycle of formaldehyde in board will be longer, which is said to take three to fifteen years. If you don't open the window regularly for ventilation, the residual formaldehyde in the room will not be discharged for a long time.
2, green plant adsorption
You can raise more plants such as flowers and plants at home, such as chlorophytum, green radish and ivy. Although plants may adsorb some harmful gases, the range of adsorption is very small. No matter how useful these plants are, whether they are green or environmentally friendly, they are beautiful at home.
3. Physical adsorption
Activated carbon adsorption of solid activated carbon has the characteristics of many pores, and has a strong adsorption and differentiation effect on formaldehyde and other harmful substances. The smaller the activated carbon particles, the better the adsorption effect.
The above small series takes you to understand the impact of formaldehyde on health in interior decoration. Everyone must study hard and keep healthy when living in a new house.
