>>>Clear seven errors in decoration pollution
Indoor environmental protection issues are a big problem, especially now that the entire human living environment is very polluting. Outdoor pollution constitutes a part of indoor pollution. In addition to the use of many decoration materials, green and environmentally friendly products inevitably carry harmful substances, not to mention The unqualified building materials were sold by unscrupulous dealers! How to minimize pollution and get a safe home? Even my experience is as follows:
1. Reduce pollution from the decoration design:
Change the idea of ​​pursuing luxury and complexity; promote grace, reduce partitions, and increase ventilation. These problems designers more than know how to oh! However, it should be emphasized that the state’s latest announcement stated that cement also contains "formaldehyde" contaminants that the World Health Organization has identified as having a strong carcinogenic cause. That is to say, unfinished rough houses are also likely to contain lethal contamination. .
2, careful to buy decoration materials:
Choosing an economical and practical green decoration material plays a decisive role in the "green decoration"! However, many of the decoration materials themselves are chemically synthesized products. It is necessary to add certain chemical components to achieve the effect. These materials are harmful to the human body. According to statistics, the utilization rate of green environmental protection materials accounts for only 22% in China. The China Environmental Product Accreditation Committee is the only entity in China that has the right to issue green environmental protection signs. When purchasing materials, be sure to recognize the “China Environment†logo on the product packaging, that is, the Ten Ring logo.
3, environmental protection building materials + green decoration:
Many owners believe that as long as they purchase environmentally-friendly building materials, they can achieve environmental protection decoration, but they do not know that environmental protection building materials do not equal environmental protection decoration. Even if it is an environmentally friendly building material, if it is used too much, the concentration of harmful substances will also exceed the standard. To combine the carrying capacity of harmful gases in the room, if the same set of living room uses three environmentally friendly large core boards without exceeding the standard, if four identical large core boards are used, it will exceed the standard. Therefore, the use of some composite building materials such as large core boards and composite boards should be minimized during the renovation.
4, timely and effective removal of harmful gases after decoration:
The natural release period of benzene series is generally within 5 years, and the natural release period of formaldehyde is generally within 15 years. These organic substances are particularly harmful to pregnant women, children and the elderly. According to an incomplete survey conducted by Beijing Children's Hospital, 90% of children with leukemia have been renovated at home. Simple ventilation will not solve the fundamental problem. Therefore, the removal of harmful gases such as formaldehyde, benzene series, and ammonia is necessary after renovation.
5, choose the appropriate governance material:
The current governance materials on the market are as follows:
1) Formaldehyde capture agent. Although there are various names on the market, they are all used to control formaldehyde, and chemically decompose formaldehyde into another relatively less harmful chemical substance. It has a direct effect and is suitable for brushing paint before it is used on plates. Use on! The harm is that there is secondary pollution, and it only works on formaldehyde, and there is nothing to do with benzene and ammonia. But now on the market to the addition of formaldehyde and benzene, this product should also be carefully screened! Don't be fooled!
2) Activated carbon adsorption method. Activated carbon is a porous carbonaceous material that is internationally recognized as a highly efficient adsorbent material and is suitable for use in enclosed spaces for the removal of contamination or odors such as drawers, cupboards, and refrigerators. However, it itself also has the disadvantages of saturable, non-decomposing, and hard to reuse, but at present, the "Cityless Charcoal" brand "Carbon Charcoal" produced by the Jinmin Group can effectively avoid its shortcomings and is worth considering. In the purchase of activated carbon, special attention should be paid to the fact that many bamboo charcoal with low adsorption capacity is used to impersonate activated carbon.
3) Ozone method. When the ozone concentration reaches 0.1PPM or more, it will play a role in sterilization odor. However, when the concentration reaches 0.15 PPM, ozone itself will emit a strong odor, and its use environment cannot exceed 30 degrees Celsius, otherwise it may cause cancer. Harsh conditions of use limit its widespread use in the civilian environment.
4) Negative ion method. Negative ions are negatively charged air. These negative ions have a direct beneficial effect on human health, but their actual life is very short, and the dirty air will further reduce its concentration. The presence of negative oxygen ions in the air is only a flash in the pan, and fleeting will not play a big role. Although negative oxygen ions can improve lung function, giving a relatively fresh feeling, there is no way to deal with indoor pollution.
5) Photocatalyst method. Photocatalyst is a generic name for a class of semiconducting materials with catalytic functions represented by titanium dioxide, which has the ability to change the activation energy of chemical reactions, thereby accelerating the speed and progress of related reactions. The use of natural light energy catalytic reaction, the air of harmful substances and microorganisms are broken down into carbon dioxide, water and other non-hazardous substances, so as to achieve the effect of purifying the air. The disadvantage is that it is difficult to achieve ideal results in the absence of light or weak light. It is helpless for places that are often hard to see the sun (such as: toilets, kitchens, cabinets, drawers, etc.) and at night.
6) Ti-Tech (Healthy Titanium) technology - from the world's top 500 US Millennium Chemicals (Millennium Chemicals), is considered to be one of the best indoor environmental science and technology in the world so far, in the world leading level, famous by France Dr. Alan, a biochemistry expert, and his technical staff have successfully developed thousands of hours of rigorous testing. It is the latest and most effective indoor pollution control product following the “photocatalystâ€, and has the power to control indoor air pollution even under conditions of no light and darkness; whether it is decoration pollution of formaldehyde, benzene, ammonia, TVOC, etc. , kitchen fume pollution, toilet odor pollution or secondhand smoke pollution, can be fully integrated governance; avoid all kinds of defects in similar products have a full state of governance effect, set indoor air pollution control, kill all kinds of harmful Virus bacteria, increase the concentration of air anion and other functions in one; construction is simple and convenient, just a spray, all problems ok pull! It does not require complicated techniques and a specific construction environment. It does not have any toxic or side effects and it is effective for 5 years. At present, the only domestic application of this technology is the "world without thieves" brand series of indoor environmental protection products.
7) Humidifier type air purification appliances. At present, the air humidifier on the market is mainly an ultrasonic humidifier and a pure humidifier. The ultrasonic humidifier uses high-frequency oscillation to atomize the water into ultra-fine particles of 1-5 micrometers. Through the pneumatic device, the water mist is diffused into the air, thereby achieving the purpose of uniformly humidifying the air. The main function of the traditional air humidifier is to regulate the indoor air humidity and keep it in a reasonable and healthy state. It solves the problem of indoor air drying to a certain extent and plays an active role in building a healthy home environment. effect. However, on the aspect of air quality improvement, especially the purification of formaldehyde, ammonia, benzene and other harmful gases brought about by interior decoration, it is very inadequate.
There is nothing absolutely absolute in this world. For the treatment of air pollution in living space, various air purification products have their advantages and disadvantages. Therefore, in the process of controlling air pollution, on the one hand, we must pay attention to daily indoor ventilation and exercise; on the other hand, love small family loves everyone and treats the environment better.
