Nowadays, it is not easy to buy a suitable house. Therefore, after the bedroom is finished dressing, people want to check in as soon as possible. However, how to remove indoor formaldehyde has become the top priority for everyone, because the excessive formaldehyde content environment is not suitable for people to live in. It is likely that the health of our products has been affected unconsciously. Therefore, the products that absorb formaldehyde have always been very popular. The most non-bamboo charcoal is the most common one. So is bamboo charcoal absorbing formaldehyde useful ? Let's take a look with Xiao Bian below. We hope to provide some help for your purchase and help you have a fresh home.
Is bamboo charcoal good for formaldehyde?
1. It was learned from some advertisements that such products have extremely strong adhesion, and they also claim to be supported by experiments. However, these experimental conditions are highly questionable. For example, they place them in nearly saturated formaldehyde vapors. At this time, the amount of formaldehyde adsorbed per gram of bamboo charcoal is as high as 68 milligrams, but the key is whether bamboo charcoal can lock the formaldehyde, and the result is disappointing. Put it in a space without formaldehyde pollution, and the above formaldehyde will be quickly released. It dropped to 34 mg in 3 hours and only 1.6 mg in one day.
2. In fact, for the adhesion of this type of product, it is mainly due to the fact that there are many microporous structures with micrometers in the size of this amorphous carbon, just like water seeps into the sand. Formaldehyde, water, and other components can all be used. The infiltration into the bamboo charcoal channel can only be blamed, but it only contains formaldehyde in the tunnel, but there is no special mechanism to limit their freedom. Just as water can be evaporated from the sand, formaldehyde can also be volatilized from charcoal.
3. According to relevant experiments, the adhesion of such products is not stable, and their harmful gases can be emitted from charcoal at any time. In addition, it can be seen from the continuing experiments of the testers that the adsorption of bamboo charcoal under high temperature is weakened. For every 100 grams of bamboo charcoal, 410 milligrams of formaldehyde can be adsorbed. It can be seen that at high temperatures, the adsorptive power is significantly reduced, and the release rate is greatly increased. Therefore, the use of bamboo charcoal is avoided where the temperature is too high.
What are the differences between bamboo charcoal and activated charcoal?
1, different processing technology
The former only through the carbonization stage, the density is relatively large, high hardness, suitable for friction wear textile products, and the latter in addition to the carbonization process, but also through the activation stage, the proportion of light, soft and fragile, not suitable for high wear resistance In the product.
2, different shapes
The former has many kinds of styles, such as flaky, cylindrical, granular, etc., and its application range is relatively wide. The latter is only powdery. Because there is no large-scale activated carbon, its application is greatly limited. The difference in production costs is also great. The price of activated carbon is much higher than that of bamboo charcoal, which is about 3-5 times that of bamboo charcoal.
3, there are differences in adsorption targets
The former pores are based on macropores, so the types of articles that can be adsorbed are relatively wide, and the latter, due to the small pore size, can cause many substances to be unable to adsorb, but for substances with small molecular diameters, the adsorptivity of activated carbon is lower than Bamboo charcoal is several times stronger.
Summary: The article is about the usefulness of bamboo charcoal to explain the knowledge, I believe that many partners have a better understanding of the use of bamboo charcoal absorption of formaldehyde , of course, if you have better suggestions and ideas, please feel free to consult Xiao Bian.
