Nowadays many parents are busy with the decoration of new homes and baby rooms, and environmental pollution and the safety of children's rooms are the first problems to be noticed and resolved. Where is the crux of the decoration of children's rooms and what safety issues should be paid attention to when selecting materials? To this end, the reporter interviewed relevant experts.
The use of materials to set aside the amount of pollution Currently, parents have to pay attention to the selection of materials in the decoration of children's rooms, but in fact, not all children's rooms with the use of environmentally friendly materials will be able to meet the environmental protection requirements. Why is this? Song Guangsheng, director of the China Indoor Environment Monitoring Center, said that this is a question of choosing a fitting design. As children's rooms are generally small, if too much material is used, it will cause an increase in the release of harmful materials. Therefore, when determining the home decoration design, it is necessary to pay attention to the space carrying capacity, the amount of indoor fresh air, and the amount of reserved pollution ahead.
Reasonable calculation of housing space carrying capacity. Currently, various decorative materials on the market will release some harmful gases. Even if it meets the national standards for hazardous materials for interior decoration materials, a certain amount of indoor space will also cause harmful substances in indoor air to exceed the standard. Therefore, what material is laid on the ground, whether the wall is painted or wallpapered, the size of the furniture, and the choice of materials, etc., must take into consideration the carrying capacity of the material in the space of the house. In the decoration of children's rooms, simple decorative materials should be used.
According to the National Indoor Air Quality Standard, indoor fresh air should be guaranteed at no less than 30 cubic meters per person per hour. In the children's room, indoor fresh air and ventilation air conditioners should also be installed.
Pre-pollution allowance for indoor purchase of children's furniture and other decorative items. Because indoor air pollution is the accumulation of various pollutants in the indoor air, if indoor hazardous materials are already up and down the national standards at the end of the renovation project, if the purchase of furniture and other decorative items, these items will also release harmful gases, Can cause excessive indoor pollutants.
Children's room decoration Carefully selected glass children's room decoration and decoration materials, glass, the biggest security risk, because although the current national safety glass requires 3C certification in order to be sold in the market, but the market's glass sales mixed, some fake and shoddy glass Thickness meets toughness requirements, but the glass process does not meet the requirements. According to reports, without the adoption of standard tempered glass is likely to burst, and children's natural dynamic, multiple collisions will increase the possibility of glass burst, so children should use little or no glass in the room.
In addition, furniture can produce toxic and harmful gases such as formaldehyde, ammonia, benzene and lead; carpets, bed blankets, and stuffed toys can cause dust mites; lead paint on wooden toys; excessive volatilization of plastic toys. Sexual material. Therefore, from the current general children's room decoration, we should also pay attention to the following three types of decorative materials:
One is to use as little as possible stone tile materials. Such materials should pay attention to their radioactive pollution, especially some natural stone such as granite, radioactive material content is relatively high, should be strictly controlled, it is best not to use.
The second is to choose waterborne wood coatings. In particular, furniture paint in children's rooms is the main source of benzene contamination in indoor air. The selection of water-based materials can fundamentally solve the problem of benzene contamination.
The third is to strictly control the man-made board materials. Such as children's room inside a variety of composite flooring, large core boards, plywood and density boards. This is the main source of indoor formaldehyde pollution. On the one hand, it is necessary to control the amount of formaldehyde used. In addition, it is necessary to eliminate the formaldehyde during the renovation.
The green construction is particularly important. After the construction and processing processes, the decoration and decoration materials have undergone complete changes in form, and the release of harmful substances in the decoration and decoration materials will inevitably also change. What really affects the release of harmful substances is the processing of materials. And compounding process. The indoor environment monitoring center has detected in recent years that due to the unreasonable construction process, the indoor environment pollution of children's rooms is also quite outstanding. The current major problems of the technology are mainly two aspects:
In terms of floor covering, some families and kindergartens worry that the laminate flooring is too thin and the children play cooler on the floor. They use large core boards to line the underlays under the laminate flooring. The use of this process to cause indoor environmental pollution is very common, mainly due to the fact that large core boards and other wood-based panels under the floor all contain formaldehyde and cannot be closed and ventilated. Moreover, the use area is relatively large, resulting in difficult to remove. Indoor formaldehyde pollution. For the problem of wall surface finishing, in accordance with the requirements of national standards, when carrying out wall surface finishing works, basic layer processing is required. Some construction workers use the process of brushing varnish to carry out the primary layer treatment, and add a large amount of thinner when brushing. It caused serious indoor benzene pollution, and it will volatilize indoors for a long time, so it is not easy to remove.
Children's room pollution five major measures 1. Children's room decoration to ensure science, environmental protection, pollution-free. In particular, care should be taken not to hit the platform, not to lay carpets, not to ceilings, and to use less colored paints and coatings.
2. Children's room furniture selection should pay attention to: in accordance with national standards for selection; at the same time pay attention to the volume of furniture should not exceed 50% of the room; plywood furniture attention to strict edge sealing and all use double panels; children's clothing to be carried in the new furniture inside Closed packaging.
3. Pay attention to the ventilation of the children's room. In order to ensure safe ventilation, windows with upper-swirl ventilation should be installed, and rooms with poor ventilation should be equipped with fresh air ventilation devices. Every day should be ventilated once and for all, should be more than half an hour each time.
4. Take care to prevent formaldehyde contamination of children's products and clothing. Such as room curtains, newly bought clothing, fabric furniture, cloth toys and so on.
5. Do a good job of indoor environmental pollution prevention and treatment, the newly renovated children's room should be ventilated and purified, according to different seasons, generally should be ventilated 15 to 30 days, should be in accordance with national standards for testing, qualified after check-in. To clean up and purify the indoor environment, we must listen to the opinions of experts and select qualified purification and treatment products to prevent secondary pollution.

Only the "screwdriver table grooving machine" for common screws, Self-tapping Screws and wood screws can ensure a certain production efficiency. Therefore, the groove "(the part matching with the screwdriver) is made into a cross shape, and the grooving process hinders the development and adoption of high-speed cold spade machines. They are called cross recessed screws.
