How to choose green building materials?

2021-04-02 12:06:24 • by deer hadware

In the production process of building materials, energy and material input, waste and pollutant emissions are all reduced to a minimum. The by-products in the manufacturing process can be reused. The products do not pollute the environment and can be recycled. The products produced are harmless to the human body and the surrounding environment.

1. Use renewable resources

Minimize or use natural resources as much as possible, and use large amounts of waste residues, garbage, and waste liquids as renewable resources.

2. Low energy consumption processes are mostly used in production technology

Try to adopt low-energy-consumption manufacturing processes and adopt clean production technologies to minimize the discharge of exhaust gas, waste residue and wastewater, and effectively purify and treat.

3. Used in the design process

The design of the product is based on the ultimate goal of improving the living environment and improving the quality of life, that is, the product not only does not harm human health, but should be beneficial to human health and make the product multifunctional. Such as antibacterial, heat insulation, flame retardant, fireproof, degaussing, anti-radiation, antistatic and adapting to human body functions.

4. Used in the production process

Do not use formaldehyde, solvents or aromatic hydrocarbons; products do not contain mercury and its compounds: lead, tin, chromium and their compounds and additives are not allowed. The following materials can be used for reference.

4.1. Selection of net decoration materials

Gypsum, talcum powder, wood, some natural stones, etc. are basically non-toxic and harmless. Because it is natural, it contains no or very few toxic and harmful substances.

4.2. Wall decoration material selection

Wall decorations such as grass wallpaper, hemp wallpaper, gauze wall cloth and other products have multiple functions such as moisturizing, insect repelling, and health care. The anti-mold wallpaper is chemically treated, which eliminates the phenomenon of mold, foaming, and growth of mold when the air is humid or the temperature difference between indoor and outdoor is large, and the surface is soft and has good air permeability.

4.3. Formaldehyde emission standards

It is slightly toxic and poses no danger to health. In the production process, processing, synthesis and other technical means are used to control the accumulation and slow release of toxic and harmful substances. Such as environmentally friendly latex paint, environmentally friendly paint and other chemically synthesized materials, which cannot be determined and evaluated by current science and technology and testing methods. Consumers should carefully select materials that are affected by toxic substances.

4.4. Tube plastic selection

In the pipe, the plastic-metal composite pipe is a high-tech product that replaces the metal pipe. The inner and outer layers are made of high-density polyethylene, and the middle is aluminum. It has the excellent properties of plastic and metal, and is not rusty and pollution-free.

4.5. Selection of paint

Biological latex paint, in addition to simple construction, has a variety of colors, which can bring colorful colors to the home. After painting, it will emit a burst of fragrance, and it can be repainted or treated with a cleaning agent, which can inhibit the mold in the wall.

4.6. Selection of health functional materials

Interior wall coatings and wall panels mixed with infrared ceramic powder have a health care effect on the human body. In recent years, many health care materials have been discovered and successfully developed. The mechanisms are mostly photochemical, piezoelectric, pyroelectric, ultrasonic, infrared biological effects and trace elements, rare earth biological effects, and negative ion effects. After the green building materials are discarded, the products can be recycled or recycled and reused without any waste that pollutes the environment.

Choosing a good building material can prolong its service life and reduce economic expenditure. Introduce 6 ways to choose right away

1. Choose a well-known brand

Choose a furniture store with a higher reputation or a better after-sales service. Try to choose solid wood furniture. If you buy furniture made of composite panels or plywood, choose products of well-known brands. It depends on whether there is a test result from the quality supervision department, especially the test result of formaldehyde. Smell for any pungent smell.

2. Materials should be environmentally friendly For consumers, environmental protection is the primary in

dicator when choosing furniture. Many furniture manufacturers claim that their furniture is absolutely environmentally friendly and absolutely green, but they will not include the corresponding indicators in the contract. If you want to buy environmentally friendly furniture, you must pay attention to it. my country currently has no special standards for environmentally friendly furniture. When purchasing furniture, consumers can choose natural and elegant solid wood furniture as their first choice when economic conditions permit. When buying furniture made of artificial boards, pay attention to whether it smells pungent. If the smell is too big, it means that the harmful chemical substances such as formaldehyde have exceeded the standard. Furniture made of natural materials such as rattan and bamboo is also a good choice.

3. Pay attention to furniture details

You can feel whether the edge sealing of the furniture is tight, and whether the moisture content of the material is too high. Because the tight edge sealing will seal the free formaldehyde in the board, it will not pollute the indoor air, and furniture with too high moisture content not only has quality problems, but also increases the release rate of formaldehyde. In addition, If the furniture you buy has caused pollution to the indoor air, in addition to paying attention to indoor ventilation, you can also buy some "formaldehyde adsorbents" to eliminate the formaldehyde released into the air by the furniture.

4. Smell the smell when choosing furniture

See if there is a strong pungent smell inside. If you are buying branded furniture, you can ask the salesperson to explain the smell reasonably and check the quality inspection certificate. If it does pass the national inspection, some smells are necessarily incidental to paint, adhesives, etc., go home It can be eliminated after opening the cabinet door for a period of time.

5. Try not to buy furniture in the morning

because the manufacturer ventilates the furniture at night, so that the pungent smell of the furniture in the morning is very small. If you go again at night, the smell of inferior furniture will be easily exposed.

6. Don't be deceived by the merchant

At the time of purchase, it is necessary to sign a contract that meets the content of the national hazardous substance limit standard. This is not only the manufacturer's commitment to consumers, but also provides a basis for consumers to protect their own interests. In order to pursue profit, some small manufacturers use the method of surreptitiously deceiving consumers. "Adjust the package" at the time of delivery. Therefore, when consumers buy furniture, the furniture contract-must be clearly written, for example, the first board-must indicate whether it is a high-quality board or an imported board, and also indicate whether it is "100% used" and whether it uses a major brand. The panel is still a veneer.
