Some questions about decorative environmental protection
Is there a standard for home decoration?
A: There are standards. The Ministry of Construction has promulgated the “Code for Indoor Environmental Pollution Control of Civil Construction Projects†(GB50325-2001), and the State Administration of Quality Supervision, Inspection and Quarantine has promulgated the National Standard for “Quality Limits for Indoor Decoration Materialsâ€.
What is home improvement pollution?
A: The materials used for interior decoration are harmful and polluting substances that pollute the indoor environment. This kind of indoor pollution from the decoration itself is called home decoration pollution. If home contaminants are too high and they are not resolved for a long time, they will cause discomfort and affect health.
What are the main pollutants in home improvement?
A: There are the following types of main pollutants in interior decoration:
formaldehyde
Benzene series; Benzene, toluene, xylene
Total volatile organic compounds (TVOC)
Free toluene diisocyanate
Soluble lead, septum, mercury, arsenic and other heavy metal elements.
Is home decoration pollution the root cause of illness?
A: Family pollution may cause people to be sick. However, there are many reasons for people to develop diseases. If the contaminants in home furnishings are too high in the newly renovated homes and cannot meet the national environmental protection standards and remain unresolved for a long period of time, the health of the home will be significantly affected. However, experts pointed out that there is still no scientific evidence that a certain disease is caused by indoor air pollution. Therefore, the prevention of air pollution exceeding standards is more important and more effective than accountability after the fact.
People mentioned that environmental protection materials and environmental protection decoration are going on?
A: The concept of environmentally friendly materials can be divided into two categories:
First, materials that are less harmful to the human body.
The second is the use of decorative materials that save resources, reduce energy consumption, and have a high rate of resource reuse.
The industry said that a class of materials is a small environmentally friendly material. The second type of material is a large environmentally friendly material. The concept of confusion will be unfavorable to your consumption, we should use a class of materials to reduce pollution hazards. Of course, mentioning the use of the second type of material is also a good thing for the benefit of the country and the people. We must use
reasonable
Use environmentally friendly decorative materials.
The true environmental protection decoration is a system: The original building structure itself has a great influence on environmental protection: indoor can maintain good convection and ventilation, and has a great relationship to reduce indoor pollution. Even if it is a room that is not renovated, the indoor air will not be very good if it cannot be windy for a long time.
Environmental design is an effective measure. We advocate a simple, modern style of decoration to reduce the amount of hazardous decorative materials used, fundamentally prevent it, and at the same time maintain as good ventilation performance as possible.
The selection of a brand-name environmental protection type of decorative materials, strict control of environmental protection indicators, and ensuring that all decorative materials meet the national environmental protection standards (or higher environmental standards) is the fundamental way to solve the problem. People often think that the use of all test materials to meet the standards is equivalent to pass, no pollution, in fact, otherwise, just up to the standard of decorative materials, if used in a certain unit space is too much, it will cause pollution exceeding the standard. Therefore, only the use of high standards of environmental protection and decorative materials, and reduce the amount of use in order to avoid accumulating excess indoor pollutants.
Many environmental protection remediation measures are also effective ways to reduce indoor pollution. For example: drying after renovation, morning and evening ventilation, air humidification, plus negative oxygen ions, green plants and so on. When decorating, pay attention to the pollution of the floor, kitchen cabinets, furniture, curtains, and other interior decorations, and consider comprehensively to prevent accumulation of pollution.
(II) Summary of Indoor Air Pollution
a, study the significance of indoor air pollution
With the progress of society, human beings have entered the information age, and it has been a long time for people to stay in the indoor environment. Whether or not the indoor air is polluted is a topic of considerable concern, especially in recent years, as people’s living standards have improved. The standard of decoration for residential and office space is getting higher and higher. There are also more and more new types of materials used in decoration and construction. When living or working in these buildings over time, many people will experience some discomforts to varying degrees, such as eye, nose or throat irritation, headache, fatigue or chest tightness, etc. Therefore, to clarify indoor air pollution and improve indoor air Quality, thus ensuring people's health, is of great significance.
b. Sources of indoor air pollution
Existing tests show that there are three main types of indoor air pollution:
Biological pollution sources:
Indoor household waste, office equipment, electrical appliances
Indoor Plant Flowers, Home Pets
Interior decoration, low quality of life
Radioactive Sources:
Soil and rock pollution in the soil under the foundation
Radioactive contamination in natural stone
Home water, gas pollution,
Chemical pollution sources:
Pollution of the building itself, pollution caused by decorative materials
Pollution caused by indoor furniture, household chemical supplies, office stationery, fabric contamination
Heating, cooking and smoking pollution, human metabolism
Emissions from the energy sector, production sectors, fuel combustion, and transportation vehicles.
Which flowers can purify the indoor air
Green plants have a good purifying effect on the air in the living room. After many years of testing, American scientist William Liver discovered that all green plants can effectively absorb the chemicals in the air and transform them into their own nutrients: In some areas 24 hours after lighting, aloe vera eliminated 1 cubic meter. 90% of the formaldehyde in the air, ivy has eliminated 90% of carbon monoxide and 86% of formaldehyde. The ability of green plants to absorb harmful substances is astonishing. In fact, most of the ability of green plants to inhale chemical substances comes from the different microbes in their potted soil, not from the leaves. In the living room, every 10 square meters of planting a pot of plants, basically can achieve the effect of decontamination. These flowers and plants used to purify indoor air: Aloe Vera, Chlorophytum, and Sansevieria can remove formaldehyde. In the 15 square meters room, two pots of tiger-tailed orchids or spider plants are planted to keep the air fresh and free from formaldehyde. Sansevieria can also release large amounts of oxygen during the day. Chlorophytum can also emit bacteriocins to kill pathogens. If there are enough spider plants in the room, 80% of the harmful substances will be killed within 24 hours: Chlorophytum can also effectively absorb carbon dioxide. Asters, astragalus, tobacco and cockscomb, these plants can absorb large amounts of uranium and other radionuclides. Ivy, Chinese rose, rose, aloe and evergreen can effectively remove indoor trichloroethylene, hydrogen sulfide, benzene and phenol. Hydrogen fluoride and ether etc. Eucalyptus, asparagus, oysters, and cactus can kill germs. Asparagus can also remove heavy metal particles. Ivy, fig, Penglai banana and aloe vera can not only deal with bacteria and other harmful substances brought back from the outdoors, but also can absorb even dust that cannot be sucked by vacuum cleaners. Monstera, Sansevieria and Chrysanthemum can absorb more than 80% of indoor harmful gases. Citrus, rosemary and spider plant. It can greatly reduce the indoor air bacteria and microorganisms. Rose can absorb more harmful gases such as hydrogen sulfide, benzene, phenol, hydrogen chloride, and ether. Wisteria, on the oxidation
