After the new house is renovated, in order to distribute the decoration pollution gas, people usually leave the house vacant for a period of time. The owners who are renovating their homes are very urgent to move into their new homes, and people in the industry point out that finding a reasonable time to move into new homes is the homework that the owners have to do after the renovation. >>> Link: Family wise decoration saves money and protects the environment “If you don’t have any newly renovated homes that have not been dealt with yet, it’s not a long time to dry them!†said a company executive who specializes in indoor environmental governance. Normally, to the newly renovated house to do testing, especially in the summer to do the test (fast discharge of harmful gases in summer), the test result is almost every household's house formaldehyde content is exceeded (China's national standard "air formaldehyde in the room Sanitary Standards stipulates that the maximum allowable concentration of formaldehyde in indoor air is 0.08 mg/m3, which is harmful to the human body if it exceeds the occupancy rate. The formaldehyde content of most new houses exceeds the national standard by 2-3 times. The main harmful substances in newly renovated rooms are formaldehyde, benzene and other volatile organics. Formaldehyde mainly comes from man-made boards and glue, and benzene comes mainly from paint. Therefore, the plates and paints including the finished furniture are the environmental protection priorities in the decoration process. "A lot of homeowners think that the furniture they buy is the highest level of environmental protection, the floor is national inspection-free products, paint is the highest environmental index, then the whole house will not be polluted!" An environmental management company's staff reminded the owners, even if all use The materials are all environmentally friendly and cannot be immediately admitted because of the superimposed effects of harmful substances, traces of harmful substances in furniture, traces of harmful substances in latex paint, and traces of harmful substances on boards and floors. It became a lot of harmful substances. >>> Link: What flowers should the children's bedroom not put? The airing skills have their own defects How to remove decoration pollution? Some use green bamboo charcoal to inhale poisonous gas, and others ask professional environmental management companies to take over the whole. These routines have become almost a necessary procedure for every family to move to their new homes, and they feel that they can rest assured that they have been retired. However, professionals are not so optimistic. In their opinion, these methods have limitations. The approach of plants adsorbing harmful substances is arguably the most environmentally friendly, but plants have the deficiencies of plants. “As everyone says mosquito repellent has no effect, it is actually exaggerating the effectiveness of insect repellent mosquitoes! The role of formaldehyde in aloe vera, green radish, etc. is also the same.†Mr. Wu of Wushan Bird and Flower Market sells flowers and plants flowers, he said for each plant. The adsorption function is the same as the air-conditioning cooling, and it is related to the size of the space. Naturally, it is beyond its ability to function. Therefore, do not expect a few plants to absorb the toxic gas in all the space in your house. To kill the virus, you need to know the effective area of ​​adsorption for each plant. It is impossible for everyone to free up all the space for plant anti-virus. Therefore, the method of using plants to absorb harmful substances is only suitable for small-sized rooms. The limitation of bamboo charcoal is similar to that of plants, and adsorption to a certain degree will saturate and require regular sun exposure. Even professional indoor environmental governance has limitations. According to reports, regarding the treatment of indoor environment, the country does not have relevant industry standards. There are only mandatory standards for “limitation of harmful substances in interior decoration materialsâ€, and there are various indoor environmental governance companies in the market. For consumers, who is looking for governance? It is really a troublesome thing. The reporter successively consulted a number of professional environmental management companies on the principle of controlling harmful gases. They gave the reporters a similar answer: First, they were sampled and tested, and then they were treated with a certain kind of syrup (usually photocatalyst, etc.). After the treatment, doors and windows need to be closed. The purpose is to allow harmful substances to react with remedies. As for how long it took to reside after governance, companies responded in different ways. Some expressed that as long as 3 days, some indicated that it would take 20 days. According to the staff of the Hangzhou Municipal Supervision and Inspection Center of the Ministry of Land and Resources, reporters told us that different pollutions require different methods of management, chemical fiber curtains have chemical fiber treatment methods, and formaldehyde has formaldehyde treatment methods. Therefore, the key to consumers is to make clear. Where is the source of pollution in the home, and then do targeted management. It is best to combine professional environmental governance and plant placement. And can not superstition governance products, we must invite qualified companies to conduct indoor environmental governance, because the effect of governance is also related to governance technology. >>> Links: 3 points to prevent the decoration of newly-married housing Environmental management knowledge What are the main sources of pollution after A home renovation? 1.

When will the new house after C decoration be able to stay After the renovation of new homes, many owners will require the decoration company to provide the acceptance results of the renovation project or indoor environmental testing results. Many owners look at those indicators and may not necessarily know which data meet the national standards. The reporter found a copy of "Code for Control of Indoor Environmental Pollution in Civil Buildings" (GB/50325 - 2001), which stipulates that indoor air quality is unqualified upon inspection and acceptance of civil construction and decoration projects and must not be delivered for use.
