Paint plays a major role in home decoration. Every home decoration, more or less, will use paint. However, few people will notice the danger of paint. The hazards of paints that are now known are roughly the same: formaldehyde, benzene, TVOC, etc.
First, what are the hazards of paint?
1. Toxicity of organic solvents
If a person inhales a vapor of an organic solvent for a long time, it will cause chronic poisoning. However, if exposed to a high concentration of organic solvent vapor for a short period of time, there is a risk of acute poisoning. In industrial hygiene, the harm of organic solvents to the human body is closely related to the volatility of solvents. At normal temperatures, low volatility solvents are less likely to pose a hazard in air. Other factors related to human harm include solvent fat solubility, reactivity, impurities, ways and means of absorption by the human body, metabolic rate of the human body, accumulation, individual feelings and sensitivities, and length of exposure.
2, the harm of paint to pregnant women
(1) It may cause skin irritation in pregnant women, causing allergic reactions, directly or indirectly affecting fetal health and normal development.
(2) It contains benzene, which can cause hemolysis in pregnant women or fetuses.
(3) The lead contained in it can enter the pregnant woman through the skin mucosa or respiratory tract, causing chronic poisoning, which damages the mother and child is the nervous system.
There are many chemical elements in the paint, which contain a lot of harmful substances. If the pregnant woman is most exposed to these harmful substances during the embryo development during the first three months of pregnancy, the harmful substances will cause the embryo to develop malformation. The most common is cleft lip and palate, if pregnant. Long-term life in these latent substances can affect the development of the fetal brain.
There are many organic solvents such as formaldehyde and benzene in the paint. These are very unfavorable to the fetus and should cause fetal malformations.
3, the biggest hazard comes from formaldehyde
The main components of the paint are oil, resin, pigment, thinner and auxiliary materials. The addition of formaldehyde to paint is one of the biggest hazards. Although formaldehyde is not the main component of paint, he acts as a counter-paint to protect the quality of the paint and to show the light after painting. Formaldehyde has a strong stimulating effect on the skin and mucous membranes. It is a combination of protoplast poison and protein, which can form formaldehyde in the body and has strong damage to the retina.
Second, how to prevent the harm of paint
Since you know the hazards of paint, you must prevent the hazards of paint. In fact, there is very little formaldehyde in the paint, and the most harmful to the human body in the paint is the benzene and benzene series and the toluene dihydrogen acid ester in the polyester paint. The measures to reduce the paint hazard are as follows:
1. After the renovation, it is ventilated enough for two months before checking in.
After the house is renovated, don't rush to stay, paint inside, the harmful gases are still not exhausted indoors. If you want to reduce the harm caused by the paint, then as long as the ventilation is enough after the decoration, it will be more than two months. Check in. If you are eager to stay, you need to use the professional to carry out inspection and control.
2, indoors placed green plants to purify the air
Some green plants can be placed indoors. Under photosynthesis, plants absorb the gas in the air and discharge the gas suitable for human breathing. But this method is slower. The plants that can be placed are ivy, spider plant, prickly pear, aloe vera, and the like.
