The problem of home environmental protection has been paid more and more attention, especially the problem of home decoration air pollution. This experience provides professional experience sharing on the problem of home decoration air pollution, hoping to help friends in need!
What is formaldehyde?
Formaldehyde is a colorless gas with strong pungent smell. It is easily soluble in water and aqueous solution. Soluble in water and ethanol, alcohol and ether. Formaldehyde is gaseous at room temperature. It is usually called formalin with 35 ~ 40% formaldehyde aqueous solution. Formaldehyde molecule has aldehyde group to produce polycondensation reaction to obtain phenolic resin (bakelite). Formaldehyde is an important organic raw material, which is mainly used in plastic industry (such as phenolic resin, urea formaldehyde plastic electric jade), synthetic fiber (such as synthetic vinylon polyvinyl formal), leather industry, medicine, dyes, etc.
What harm does formaldehyde do to human body?
1 stimulation
The main harm of formaldehyde is to stimulate the skin and mucous membrane. Formaldehyde is a protoplasm toxic substance, which can combine with protein. When inhaled in high concentration, it will cause serious irritation and edema of respiratory tract, eye irritation and headache.
2 sensitization
Direct skin contact with formaldehyde can cause allergic dermatitis, stain and necrosis. Inhalation of high concentration formaldehyde can induce bronchial asthma.
3 mutagenicity
High concentration formaldehyde is also a genotoxic substance. Nasopharyngeal tumors can be caused by high concentration inhalation in laboratory animals.
4 outstanding performance
Headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, poor appetite, palpitation, insomnia, weight loss, memory loss and autonomic nerve disorder; Long term inhalation by pregnant women may lead to fetal malformation and even death. Long term inhalation by men can lead to sperm malformation and death.
What harmful gases will be produced by new house decoration?
The main harmful gases produced by new house decoration are formaldehyde, benzene, ammonia, radon, TVOC, etc.
1. Open windows to keep the house ventilated.
Take away and dilute harmful gases in the room by allowing the natural circulation and replacement of indoor air. This method is the most original and effective method.
2 plant removal method.
Such plants are Chlorophytum, tiger skin orchid, ivy, aloe, Agave, Gerbera.
3 activated carbon adsorption method.
Using activated carbon and bamboo charcoal with adsorption function to remove these harmful gases is also the most widely used method at present. However, it is certain that the action space of activated carbon is small. If the space is large, the amount of activated carbon to be used is also relatively large.
4 formaldehyde scavenger removal method.
This method is the most direct and effective, but the requirements for products are also very professional. At present, such products include chemical products, nano photocatalysts, plant stock solution formaldehyde removal products, etc. This kind of product will be somewhat 'secondary pollution', so it should be used with caution.
5 soil method.
300g black tea, make hot tea, put two basins of water into the room, and open the window for ventilation. In addition, you can put some grapefruit peel, orange peel, pineapple and so on indoors. These things have a certain effect.
What are the types of formaldehyde removal products with good reputation in the market?
1. Activated carbon products
2. Chemicals formaldehyde removal products
3. Plant stock liquid scavenger
There are two ways to determine the pollution level of your house
One is through sensory judgment.
1. When the formaldehyde content in indoor air is 0.1mg/m3, there is discomfort;
2. When the content of formaldehyde in indoor air is 0.2mg/m3, it can cause pharyngitis, conjunctivitis and asthma;
3. When the formaldehyde content in indoor air is 0.5mg/m3, it can stimulate eyes and cause tears;
4. When the content of formaldehyde in indoor air is 0.6mg/m3, it causes sore throat;
Second, it is detected by formaldehyde detection box.
Formaldehyde detection box can be purchased online, and the price is generally 6-9 yuan.
