Decoration can not be separated from a variety of building materials, and these materials often contain harmful substances, such as synthetic flooring, plywood, paint, paint and other harmful gases containing formaldehyde and benzene, as well as heavy metals such as lead, mercury, cadmium, chromium; Artificial floor tiles made of natural marble, crystal balls and natural stones, which are decorative materials, contain radiation and helium (the floor tiles with high hardness and bright colors are added with the highest level of radiation).
In addition, microbial contamination (such as insects, bacteria), electromagnetic radiation pollution and inhalable particulate matter pollution are also many. These pollutants can make children become associated with a variety of diseases such as aplastic anemia, leukemia and other blood diseases, asthma, heavy metal poisoning and mental decline, and become a new "killer" for children's health. According to the data, among the children aged 1 to 5 years old, the proportion of children who suffer from environmental pollution accounts for 30% of the total number of sick children. The number of people with upper respiratory tract infections is up to one million each year due to decoration pollution.
preventive solution:
Children's room decoration must be based on the child's health, science, strict control of formaldehyde, ammonia, benzene, lead and other harmful substances, carbon dioxide concentration of less than 0.1%, relative humidity maintained between 30% ~ 70%. Specifically, pay attention to the following major links:
- Scientific selection. Regardless of the main material or auxiliary materials, materials that are environmentally friendly and meet the relevant national quality standards should be selected. In particular, attention should be paid to the formaldehyde content in the laminate flooring, the radioactivity of the stone and the xylene content of the coating.
- Promote minimalist decoration and minimize the amount of decoration materials used. The reason is very simple, environmentally friendly materials are not completely free of contaminants, but the harmful gases they release in a certain space are in a safe range. If these materials are used in large amounts in the room, the concentration of pollutants may exceed the standard. Therefore, according to the reasonable design of the room area, choose a non-polluting construction process, try to block the source of harmful substances.
- The decoration of the children's room should be stricter, at least seven: no wallpaper, no marble and granite (the source of pollution), no floor, no carpet, no ceiling, no plastic floor, no oil Paint (replaces water-based paints with relatively low levels of heavy metals) to reduce the production of volatile organic compounds in the room.
- After the house is renovated, especially in the children's room, ventilation must be carried out to purify the indoor air. According to different seasons, it should be ventilated for at least 15 to 30 days, and then checked according to national standards before entering.
- Reasonably configured furniture. If you choose furniture, you must see if there is any national standard environmental testing report. If economic conditions permit, natural and elegant solid wood furniture can be used as the first choice. Secondly, natural resin decorative furniture is also good. Wood-based panel furniture should pay attention to strict edge sealing and all use double. The panel is to ensure the safety of the child; the density of the furniture is designed according to the space capacity of the room, and the volume of the furniture should not exceed 50% of the room.
- Diligently ventilating and ventilating, diluting the indoor pollutants with the dilution of fresh air, so that the harmful gases in the decoration materials are discharged as soon as possible. Generally, after 10 o'clock in the morning, it can be ventilated for 20 to 30 minutes in three times in the morning, in the middle and in the evening.
- Conditional households can install indoor air purification equipment, such as negative ion purification equipment, electric air purifiers, etc., to enhance indoor air purification, minimize decoration pollution, and ensure the healthy growth of the next generation.
Ground Anchor / Earth Auger is a device designed to support structures, most commonly used in geotechnical and construction applications. Also known as earth auger, percussion driven Earth Anchor or mechanical anchor, it may be impact driven into the ground or run in spirally, depending on its design and intended force-resistance characteristics.
Earth augers are used in both temporary or permanent applications, including supporting retaining walls,guyed masts, and circus tents.garden or vineyard fence & .
Ground anchor mainly made of carbon steel/ thread steel ,with high dip galvanized surface treatment or powder coated treatment .
There are many colors of ground anchor ,such as black ,white ,red colors .
diameter of ground anchor pole :13-16 mm,length 30-60' or according to clients' request .
In addition to earth anchor,we also supply earth auger,Helical Ground Screw Anchor,Helical Ground Anchor,ground anchor pile,anchor bolt.
