How to identify the quality of activated carbon filters.
1.Look at the weight. The more pores and the more complex the structure, the stronger the adsorption capacity and the better the quality of the filter element.
But we can't distinguish it with the naked eye when we buy it, and we can identify it by our feel. The more pores, the lighter the weight of the activated carbon (compared to the same size filter), so the premium activated carbon filter is relatively lighter.
2.Look at the index. In the introduction of the filter element, we talked about three indexes, we can look at these three indicators on the filter element, the higher the index, the stronger the adsorption capacity. The quality of the activated carbon filter is better.
3.By the method of combustion. We can break a little bit of the strainer, and then take out some activated charcoal, put it on the fire to burn, and then take it away, if it immediately turns black gray, it is really activated carbon, if it turns white gray and is very red, it is made of charcoal.
2.When buying activated carbon filters, try to buy them at the place designated by the water purifier brand. For example, if you buy Midea's activated carbon filter, you can go to Midea's specialty store or physical store to buy it, so that the quality can be assured.

The iodine value you mentioned is a measure of a certain characteristic of activated carbon, and does not necessarily represent the quality of activated carbon, just as milk with high protein content is not necessarily good milk. The most important thing is to look at the effect of the product, and good effect is the last word. Always believe that you get what you pay for.
-
It is recommended to buy activated carbon with 600-800 iodine value, which is low in price and extremely cost-effective.
The iodine value is more than 850, ** doubled, there is no economic value, and it is okay to engage in retail.
600-800 activated carbon, you can also increase the iodine value by physical crushing method, and the iodine value is not fixed.
-
The iodine value is an indicator of the degree of unsaturation in an organic compound. Refers to the number of grams of iodine that can be absorbed (added) in 100g of substance. It is mainly used for the determination of oils, fatty acids, waxes and polyesters.
The greater the degree of unsaturation, the higher the iodine value. The iodine value of dry oils is greater than that of non-dry oils.
It is mainly used for the determination of oils, fatty acids, waxes and polyesters. The greater the degree of unsaturation, the higher the iodine value. The iodine value of dry oils is greater than that of non-dry oils.
It should be noted that if there are two or more olene groups in the molecular structure of the oil, the iodine value is only true if these alkene groups are in the unconjugated state.
-
Activated carbon has a very large relative surface area due to its loose and porous nature, and has strong adsorption.
In the tap water purification process, the adsorption purification with activated carbon is generally used after filtration. At this time, the obtained water is relatively clear, containing a small amount of insoluble impurities, more soluble impurities (calcium and magnesium compounds), odor, color.
It can adsorb a small amount of insoluble impurities remaining in the water.
Adsorbs most soluble impurities.
Absorbs odors in water.
Adsorption of color in the water, making the water transparent and clear.
The water adsorbed by activated carbon can be used as domestic water after chlorine disinfection.
-
The main thing is adsorption, which cannot remove heavy metal ions and pesticide residues in the water.
-
The specific surface is large and the adsorption capacity is strong.
-
Look at the composition, look at the pore size component, and look at the particle size.
1. First of all, we must know what activated carbon is, activated carbon is also known as activated carbon black. It is amorphous carbon in the form of black powder or granules. In addition to carbon, the main components of activated carbon include oxygen, hydrogen and other elements.
This is the reason why activated carbon is a hydrophobic adsorbent. Next, let's introduce which activated carbon will be better.
2. Activated carbon is nothing more than black granular matter on the surface, teaching to distinguish the quality of good or bad: because activated carbon is non-toxic, you can make activated carbon into small particles, so that its broken section is exposed, and then dry the moisture on the tongue, close the section to the tip of the tongue, you can feel that there is a force of adsorption, and the activated carbon will even pull the tongue pain. Activated carbon without adsorption is either of poor quality or moisture absorption.
3. In addition, you can also do a bubble experiment. When a small handful of activated carbon is thrown into the water, the water will gradually penetrate into the pores of the activated carbon, forcing the air in the pores to expel it, thus creating a series of extremely fine bubbles, pulling a fine line of bubbles in the water, and at the same time making a hissing bubble sound. The more intense this phenomenon occurs and the longer it lasts, the better the adsorption of activated carbon.
One look at the composition, the second look at the pore size component, the third look at the particle size, the fourth look at the dust, the fifth look at the enterprise, the sixth look at the packaging, and the seventh look at the size of the carbon bag.

Activated carbon adsorbs and removes formaldehyde.
Bamboo charcoal and activated charcoal are recognized as drug addicts.
How much activated carbon is put in: Generally speaking, 600g of activated carbon is suitable for 10 square meters of space, every 20 days or so, the activated carbon is exploded for three or four hours, and then reused, it can generally be used for 5-8 months, and the house is best ventilated when using activated carbon, so that formaldehyde will be removed faster.
If the plant is medium to low formaldehyde, you can choose to put a few pots of potted plants at home.
Note: In general, in a room of about 10 square meters, two pots of food with a height of one meter are enough.
Photocatalyst decomposes formaldehyde.
An important part of accelerating the decomposition of formaldehyde and toluene is to effectively use the clear mangreen nano photocatalyst to decompose formaldehyde in the air under the action of light (ultraviolet rays, light lamps, etc.). Healthy and convenient. Just spray lightly for a week, and the formaldehyde content is no longer a luxury.
Every family has a healthy dream to help you achieve your healthy life.

Activated charcoal is one of the main ingredients of the disinfectant mask, which is left in the sun for a few hours after a period of time to restore the purifying effect. That's one of the reasons.
1. The public's method of removing formaldehyde is ventilation, raising some plants or some effects, you can raise some spider plants, aloe vera, cactus, tiger tail orchid and other flowers to absorb indoor pollution gases, and use some plant extracts for wooden furniture or flooring at home to effectively decompose formaldehyde.
2. If you are not at ease, use some formaldehyde removal materials, such as Ye Guang mud, activated carbon has a simple effect of adsorbing formaldehyde, will not adsorb saturation, no secondary pollution, will be better than activated carbon, and the range of application is also wider.
-
The volatilization period of formaldehyde is 3-15 years, the time is very long, and the formaldehyde can not be removed quickly, and the activated carbon is effective in a short time, and it will not be able to adsorb well after a long time.
-
Activated carbon is amorphous carbon in the form of black powders or granules. In terms of structure, activated carbon is irregularly arranged due to the microcrystalline carbon, and there are fine pores between the cross-connections, which adsorbs harmful gases such as formaldehyde and benzene. Proper heating of the adsorbed solution can increase the adsorption rate of pigment, strengthen the adsorption effect, and accelerate the removal effect of pigment due to the high temperature is conducive to intermolecular Brownian motion.
Activated carbon can remove formaldehyde, the effect is very good, like Qingyi activated carbon made of coconut shell is very good, can effectively remove formaldehyde and other harmful gases.
-
When choosing activated carbon, it is best to use fruit shell charcoal or coconut shell charcoal, especially coconut coconut carbon, coconut carbon is a new type of activated carbon, is a new process carbon, coconut shell as raw material, after high temperature activation, carbonization treatment, while loading photocatalyst, carbon fiber made of a new type of activated carbon, can adsorb formaldehyde, benzene, ammonia and other toxic and harmful nano-scale small molecule polar substances in the air, with fast adsorption speed, for polar molecules, can be recycled.

Activated carbon is a type of carbon with strong adsorption capacity, and the most well-known use is gas masks. Activated carbon is also very effective in removing indoor formaldehyde, so let's take a look at how effective activated carbon is!
1.High-efficiency and environmentally friendly activated carbon package can adsorb formaldehyde and other indoor harmful gases in the air, quickly eliminate decoration odors, evenly adjust the humidity of the space, and have a good effect on formaldehyde in many indoor and outdoor areas.
2.Activated carbon has a strong "physical adsorption" and "chemical adsorption" effect, which can adsorb some organic compounds to achieve the removal effect, using this principle, we can quickly and effectively remove formaldehyde, so that the indoor air can be directly and quickly improved.
3.The adsorption of activated carbon is affected by the temperature, humidity and air pressure of the environment, when it is saturated or will be saturated, the ambient temperature rises or the air pressure becomes low, and the adsorbed pollutants will be released outward, and the pollutants that are temporarily adsorbed will return to the indoor air.
I believe that everyone has understood the role of activated carbon after reading the above content! You can buy it if you need it!

Water purifier is a commonly used water purification equipment in modern life, which has played a leading role in escorting the safety of domestic water. How to choose the filter element filled inside?
1. The former Hui local section is equipped with a granular pre-reputation carbon filter element.
As the pre-filter element of the water purifier used in the carbon, in principle, to choose the excellent quality of the carbon, such as low ash, low sulfur coal carbon, all kinds of shell carbon, among which coconut shell activated carbon is the best, if in order to prevent the initial use, the occurrence of black water, as far as possible to choose washing, pickling charcoal, which will make the production cost of the water purifier rise. The specific target of charcoal should be set according to the practical situation.
2. Rear granular carbon filter element.
The main function of the post-granular carbon filter element is to effectively improve the taste of the water, so it is best to choose high-quality coconut shell charcoal with high iodine value, strict pickling or water washing, and the particle size is best in 20-40 mesh, which is the standard.

Pre-filter: Generally installed behind the water meter of the inlet pipeline, it is the first coarse filtration equipment for the whole house water, which can filter sediment, rust and large particulate matter in the tap water, and can also stabilize the water pressure and protect the water purification equipment connected to the back.
**Water purifier: Mainly through the KDF filter element and activated carbon adsorption, the water quality is effectively purified, and the water may contain sediment, rust, bacteria, suspended solids, algae, macromolecular organic matter and other harmful substances, and the minerals that are beneficial to the human body in the tap water are retained, and the treated water meets the standard of drinking water.
**Water softener: through natural resin to replace the calcium and magnesium ions in the water, reduce the hardness of the water, soften the water quality, reduce the wear and tear of the minerals in the water on the clothes and **, can care for the skin, protect the clothing, and can also avoid the formation of macular spots by the minerals in the water in the sanitary ware and tableware, so as to avoid the scale generated by the water pipe and the water heater shower, and facilitate the use of domestic water.
Terminal direct drinking machine: using high-precision five-stage filtration process, the tap water is filtered at the water terminal, and the water comes out to meet the raw drinking standard, and the faucet can be drunk directly, which avoids secondary pollution, and the water quality activity is large, and the oxygen content is high, which can promote human metabolism and enhance the vitality of human cells.
Common sense to know when buying a household water purifier.
First, the filter element, the filter element is like the heart of the water purifier. For example, many consumers follow the online purchase strategy, after buying a water purifier, they find that the purified water quality has indeed improved significantly, and impurities and scale have been greatly reduced, which seems to be very reassuring. But after a period of time, many consumers will point out that the filter element is often ignored in the process of using water purifiers.
The reason is not only because of the busy work, the effective use time of the multi-stage filter element is different, and it needs to be replaced regularly, but also brings great trouble to the home water purification. According to a technical engineer, the length of use of the filter element is mainly related to the water consumption of the family and the cleanliness of the water quality.
In addition, the technician also introduced: every time to the occasion of important national holidays, the water purifier industry has also begun to be active, some speculators in order to improve their product advantages to attract consumers, claiming that their filter elements can be used permanently without replacement, consumers should not be greedy and gullible this kind of propaganda, after all, drinking water safety is related to health matters.
Second, look at the water purifier product qualification certification. The domestic drinking water system has passed the test of the Ministry of Health of the People's Republic of China and received the "China Wading Product Certification", which can be directly inquired on the official website of the Ministry of Health of China. For imported products, you can check whether the product has an import and export inspection report.
The general unit has a technician to install, you buy it in **, then the unit should give you free installation, our unit is like this I don't know about other units.
There are a few more well-known water purifiers, such as Aihuipu Bainuoken 3m Danone Waters Smith Norite and other imported water purifiers, there are also many domestic ones, and they should be installed according to their own needs, the most important thing is to choose their own suitability, if you don't understand, you can call for consultation"Three-point water purification supermarket"to provide free consultation services.
The details are as follows: At present, water purifiers have been developed in China for more than ten years, and the industry has formed a mature industrial chain system. Especially in recent years, the popularity of smart home has also stimulated the development of water purifiers and other related industries, especially in 2015 and 2016, the water purifier industry has developed rapidly. >>>More
