Decoration material to formaldehyde has a coup

Nowadays, more and more people are demanding personalization in the renovation of new houses, and they are also striving for the environmental protection of the decoration materials. Because a variety of decoration materials will emit a series of carcinogenic substances such as ammonia, formaldehyde, benzene and benzene series. Formaldehyde is undoubtedly the most troublesome of all indoor air pollutants. According to the World Health Organization’s publication No. 153, formaldehyde has strong carcinogenic properties and can irritate the eyes and respiratory mucosa, causing headache and fatigue, nausea and vomiting, and palpitations and insomnia. And there is enough evidence that inhalation of formaldehyde is also related to diseases such as leukemia and lung cancer. And because formaldehyde remains in the low-level air in the house, and children's own resistance is weak, formaldehyde is more harmful to children. Since these volatile gases have a volatile time of 3 to 15 years, prevention should be strengthened in a long-term and effective methods should be adopted to remove formaldehyde and reduce its harm to the human body. Here are some methods for removing formaldehyde.

Plant absorption method

Some plants have the ability to absorb formaldehyde, such as cacti, spider plants, aloe vera, tiger pea, and cycad. Under normal circumstances, about 10 square meters of room, 1.5 meters high plants put two pots more appropriate. The method of placing plants is suitable for lightly contaminated rooms. In rooms with high levels of formaldehyde, these plants can only play an auxiliary role and do not completely remove formaldehyde.

Activated carbon adsorption

Activated carbon has many characteristics of pores, and it has strong adsorption and decomposition of harmful substances such as formaldehyde. But for heavily polluted rooms, it cannot be completely absorbed. In general, about 15 to 20 square meters of room, it is recommended to use about 1000 grams of activated carbon. Each drawer cabinet, placed 1 to 2 packets (50 grams / bag). However, since the adsorption of activated carbon is apt to saturate, one month after Kaifeng is used, it is necessary to expose the activated carbon to exposure under the hot sun to release hazardous gases before it can be reused. However, the actual effect is not ideal, and the adsorption rate is less than 5%.

Purifier treatment

A good air purifier can quickly and effectively eliminate formaldehyde from the air. It should be noted that air purifiers must be kept on frequently to ensure the quality of air in the home. After the expiration date, the air purifier filter system must be replaced.

Ventilation method

Indoor air is often circulated, which can reduce the formaldehyde content in the air and reduce its harm to the human body. Because of the long period of release of harmful substances in the room, the home has to open windows for a long time to keep the air flowing. Some old people use earthy methods to remove formaldehyde, put tea residue, grapefruit skin, onion slices, pineapple blocks, etc. in a room that has just been renovated, or use white vinegar to fumigate the entire room. In fact, this will not reduce the formaldehyde in the air, but it will only serve to cover up the pungent odor. Some people also like to use air fresheners, and the chemicals in air fresheners may react with formaldehyde, causing secondary pollution.

Algal Calcium Decomposition

In addition to the above methods, the use of calcium algae to remove indoor formaldehyde is a very good choice. Algae calcium air purification product is a new type of scientific and technological product developed by Hubei Greenson New Building Materials Technology Co., Ltd. over several years. It is different from the traditional bamboo charcoal bag, activated carbon can only adsorb formaldehyde and other air pollutants, algae calcium as a new type of technology environmental protection The material, which uses photocatalytic technology to decompose and purify formaldehyde and other harmful gases and all kinds of odors, reached an index of purification rate of more than 95%. Not only can quickly remove formaldehyde and other harmful gases in the building, but also solve other odor release problems, and its 90% continuous rate indicator ensures that this purifying ability will not decay for at least 20 years. Continuous release of negative oxygen ions improves and enhances indoor air quality. The negative oxygen ions are not affected by the natural environment, equipment and instruments, and have functions of sterilization, disinfection and cleanliness of the air, and will not cause secondary pollution to the air due to saturation of adsorption.
