How to remove formaldehyde after the new house decoration?

Everyone will encounter a problem when decorating the new house, that is, the harm and removal of formaldehyde. It is found that the formaldehyde emission from the decoration materials is very harmful to the human body, and the newly decorated room has a high content of formaldehyde, which is the main cause of many diseases. Many people feel uncomfortable after living in a new house for some time. Sometimes they feel dyspnea, asthma and chest tightness. In fact, you are not sick, but the symptoms of excessive absorption of formaldehyde. Since the new house decoration formaldehyde emission is so fierce, then how to remove formaldehyde after the renovation of the new house?

　One. Characteristics of formaldehyde:

　　Formaldehyde is not scavenged by water, formaldehyde, chemical formula HCHO or CH O, molecular weight 30.03, also known as Ants. Colorless gas has special irritating odors, which irritate people's eyes and nose.

　Two, the harm of formaldehyde:

　　1, the main hazard of formaldehyde is the stimulation of skin and mucous membrane. When formaldehyde reaches a certain concentration indoors, people feel uncomfortable. Formaldehyde concentration greater than 0.08m can cause eye irritation, eye itch, throat discomfort or pain, hoarseness, sneezing, chest tightness, asthma, dermatitis, etc. Formaldehyde content in newly decorated rooms is high, which is the main cause of many diseases.　

2, the high concentration of formaldehyde will cause acute poisoning, manifested as sore throat burning pain, dyspnea, pulmonary edema, anaphylactoid purpura, allergic dermatitis, liver transaminase increase, jaundice, etc.

　Three, the prevention of formaldehyde:

　　1, the main volatile components of formaldehyde are decoration materials, home and so on, choose natural decoration materials, choose and prevent from the source of materials.

　　2, the decoration should be moderate. The adhesives, paints and so on in the decoration materials are all chemically synthesized, and formaldehyde, benzene and so on are all very high. To reduce formaldehyde pollution, decoration must be moderate. You have economic strength, but your ability to fight pollution is not stronger than others. Do not blindly pursue luxury atmosphere, because the more complex the decoration, the more decoration materials used, means the greater the possibility of pollution, the higher the degree of pollution. Simple and simple.　　

      3. try to choose regular furniture decoration materials, including furniture selection. The more famous manufacturers pay more attention to their reputation, the better the quality of paints and paints used in the production process.

  Four. Remove the method of formaldehyde:

　1.ventilation method, through the circulation of indoor air, can reduce the content of harmful substances in indoor air, thereby reducing the harm of such substances to the human body.

　2. Physical adsorption, the porous structure of activated bamboo charcoal bags provide a large number of surface areas, making it very easy to achieve the purpose of absorbing and collecting formaldehyde. At present, bamboo charcoal bags are relatively good, and bamboo charcoal is made by firing more than five years of bamboo. It has fine porous, hard texture, good aeration, good water permeability, good water retention and large surface area, and has strong adsorption property. It can effectively absorb formaldehyde, sulfur dioxide, chlorohydrocarbon, organophosphorus and carbamate insecticides in the new house, and can also adsorb benzyl ether, nitrochlorobenzene, naphthalene, ethylene, xylene, phenol, DDT, aldrin, alkylbenzene sulfonic acid and many esters and aromatics.

　3, negative ion method, negative ions can effectively remove indoor formaldehyde and other harmful gases, and purify indoor air. The Chinese Academy of Sciences has proved by experiments that the effective rate of removing small amounts of formaldehyde by small particles is more than 73.33%, and its long-term usage is up to 99%.
