Environmentally friendly wood flooring, as its name implies, is a floor with less pollution, but the national assessment criteria for environmentally friendly wood flooring are:
The national standard stipulates that the formaldehyde emission of the floor is less than or equal to 1.5mg/L, which is in line with the new national standard and meets the indoor environmental health requirements.
Then the question is coming, how should the environmental protection wooden floor be judged?
A simple way to judge environmentally friendly wood flooring:
Saw the wooden floor into a new section, carefully smell and see. If there is a pungent smell or a glare, it must be a substandard product with excessive formaldehyde. Otherwise, it can be basically determined to be an environmentally friendly product.
In addition, consumers can soak the top of a small sample in boiling water for 1-3 minutes to see if there is a pungent odor. Because of the low formaldehyde emission, environmentally friendly wood flooring generally does not smell pungent odor. If the irritating odor is strong and even makes the eyes feel uncomfortable, it proves that there is more free formaldehyde in the substrate of the floor.
In addition to the fact that the floor itself contains formaldehyde, it will cause pollution to the indoor environment. If you choose the floor, you cannot ignore the installation problem. If the installation is not standardized, it will also have an impact on the environment. In addition, if the adhesive in the floor does not meet the standard, it will also cause indoor formaldehyde pollution. Therefore, in the choice of wood flooring with good environmental performance, consumers should also pay attention to the environmental cleanliness of the relevant processes.
Other methods for judging environmentally friendly wood flooring:
1, judge the environmental protection wood floor to see the packaging
Look at the packaging and see the certificate. Generally, regular manufacturers, whether purely imported or domestically produced, will use Chinese or Chinese and English text marks in packaging. Regular manufacturers use environmentally friendly raw materials in order to maintain their reputation, and the behavior of small factories is difficult to guarantee.
2, judge the environmental protection wood floor asked experts
Ask the industry insiders or consult a relatives and friends who know how to do it before buying, let them recommend it, and focus on the technical instructions and usage feelings. Or go to the building materials market to run the business, shop around, Mo is cheap to buy inferior products, then regret it is too late.
3, judge the environmental protection wood floor pro experience
See more and know more. If you want to buy a comfortable floor, you must know the common sense of the floor. In addition to well-known indicators such as formaldehyde emission and wear resistance, there are many key indicators such as water swelling rate, static bending strength and dimensional stability, which also affect the performance of the floor.
Deep Groove Ball Bearings
Deep groove ball bearings The out looks of them are nearly the same,the only different is the size,you may need other models please check the following table for reference.are the most widely used bearing type and are particularly versatile.
They have low friction and are optimized for low noise and low vibration which enables high rotational speeds.
They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
Deep groove ball bearings are divided into the following series: 6000series, 6100series, 6200series, 6300series, 6400 series, 6700 series, 6800 series,6900 series,16000 series etc.
