How to decorate children's room before "green" [Figure]

Decoration, we must know that the processing, construction, use of decorative materials, and even temperature and humidity will affect the release of harmful substances. Therefore, green decoration must be checked from four aspects: green building materials, green construction, testing and governance. Choosing green building materials Use natural materials such as wooden materials in the decoration of children's rooms as much as possible, but try to avoid using natural stone because of the radioactive hazards in natural stone. In addition, it is better to select materials with less harmful substances and less emissions, that is, to use decoration materials that conform to the ten national standards for “restrictions on hazardous materials for interior decoration materials”. Materials that exceed this standard are definitely not used. In particular, some paints, wood-based panels, materials, and rubber products must be tested. After the construction and processing of green construction decoration materials have undergone a complete change in form, the release of harmful substances in the decoration materials will inevitably also change. The real impact on the release of harmful substances is the processing of materials and Compounding process. For example, if you make a door and use one big core board and one plywood that meets the national standards, and after processing and brushing the paint three times to form the door, the amount of harmful substances released must be very different from that before processing. It is this compound situation that affects the air quality index. Therefore, it is necessary to select a decoration material with a small number of processing steps. Children's room environment has indicators According to the relevant national regulations, the indoor environment in children's rooms has indicators: carbon dioxide is less than 0.1%; carbon monoxide is less than 5 milligrams per cubic meter; bacteria is less than 10 dishes; temperature is controlled at 18 degrees Celsius or more in winter. Summer is controlled below 28 degrees Celsius; humidity should be guaranteed between 30% and 70%; noise should be less than 50 decibels... In addition, some indoor environmental indicators are: The amount of formaldehyde released from the artificial board used in the decoration project should be limited. Less than 1.5mg/L; the concentration of helium in each cubic meter of air in a building is 200 beck; the maximum allowable concentration of harmful substances in the air of residential areas is the standard for air ammonia, and the controlled concentration of ammonia per cubic meter of air is not more than 0.2 mg... After the children's room is renovated, it's best to ask the testing department to come and test at home. Prevention and treatment of indoor air pollution Before the decoration of children's rooms, parents should ask the relevant indoor air testing department to do “pre-evaluation”, that is, let environmental protection experts explain whether the materials and processes used in the design scheme can affect the microclimate of the children’s room. . It is understood that indoor microclimate conditions include the following aspects: temperature, humidity, relative humidity, wind speed, air pressure and so on. In addition, after the children's room decoration, pay attention to ventilation. According to tests conducted by indoor environment experts, the frequency of indoor air replacement directly affects the content of indoor air harmful substances. The more frequent indoor ventilation or the use of air filters, displacers, etc., the less harmful or harmful substances in the air will be.
