>>>Links: What plants are the most "drugs" in newly renovated rooms?
Misunderstanding of a vinegar fumigation
Some consumers try to fumigate vinegar to remove the odor after home decoration. Experts pointed out that vinegar is an acidic substance that has the effect of weakly neutralizing ammonia in the air, but does not react with other harmful components such as formaldehyde.
Misunderstanding two place pineapple
Some people think that putting a few pineapples in each room can eliminate the smell of paint and put more room in larger rooms. The pineapple will volatilize the aroma and play a role in masking the odor, but it does not decompose and remove harmful substances. In addition, the pineapple contains a lot of water, and after the volatilization, it plays a role of humidification, which can play the role of dissolving formaldehyde and other harmful substances, but once Dry formaldehyde will volatilize again.
Misunderstanding three over-dependence on plants
Some ornamental plants can indeed absorb certain toxic gases. For example, plants that can absorb formaldehyde include cactus, spider plant, aloe vera, ivy, cycad, chrysanthemum, etc.; and three types of flowers such as ivy, cycad, and chrysanthemum all have the ability to absorb benzene. , can reduce benzene pollution. But the key is that their role is quite limited. Facing the dense distribution of harmful gases at the end of renovation, their weak absorption will not only eliminate pollution to the Savior, but even their own health. A consumer once said: “The flowers in my old house have just been placed in a new house and the leaves will be yellow in a few days.†Experts said that this may be caused by indoor pollution.
Misunderstanding four tea roots
Some people even put dried tea roots in tea cups in the closet and room, hoping to help clear the gas. As everyone knows, tea roots are as effective as dry leaves and toilet paper in this regard, with almost no absorption and decomposition.
Misunderstanding five superstitious environmental protection building materials
The use of environmentally friendly building materials helps to reduce indoor harmful gases, but:
First of all: China's national standard for green building materials is not ideal. When formulating standards for environmental protection building materials, due to scruples on the current low-level production status of most domestic building materials companies, some of the current standards can only be said to be reluctant to go because there will be a large number of enterprises with slightly higher standards. Guan Zhang, the relevant industry regulators several times want to improve some of the standards to move closer to international standards, all because of this.
Second: Even if all environmentally friendly building materials are used, the final air quality may exceed the standard. Because most of the environmentally friendly building materials only contain harmful substances and emit harmful gases below a certain standard, they do not contain harmful substances at all, and they do not emit harmful gases at all. In addition, due to factors such as decoration design, residential structure, and ventilation, due to the superposition of harmful gases, As a result, there is still no guarantee that indoor air quality will be up to standard after indoor decoration.
Myth 6 relies entirely on short-term ventilation
Ventilation treatment as a basic environmental protection measure will improve the indoor pollution, but because most of the harmful substances will be slowly released for 3-15 years, it will not be a matter of months of ventilation to solve the problem in its intensive dissemination period 1- Within 3 years, you have to take a greater risk of causing diseases and cancers; and in northern China, doors and windows need to be closed in winter and summer, and in addition, most rooms and office buildings are not ideal for ventilation, and ventilation will be greatly reduced. In addition, formaldehyde is used as an example. Free, adsorbed, combined with the three states exist. Only the ventilation treatment in the free state can be eliminated and it must be more than four times the normal wind speed.
Misunderstanding 7 considers strongly irritating scent to consider environmental protection
Like human health conditions, the indoor air environment has three forms: healthy, sub-healthy, and sick. Many harmful gases are colorless and odorless. Like treating diseases, the indoor air environment also needs prevention, health care, and treatment. Like home health doctors, professional indoor environmental companies provide you with a healthier indoor environment by providing environmental protection services.

Electrical Switchgear Protection
Definition of Switchgear
A switchgear or electrical switchgear is a generic term which includes all the switching devices associated with mainly power system protection. It also includes all devices associated with control, metering and regulating of electrical power system. Assembly of such devices in a logical manner forms switchgear. In other words apparatus used for switching, controlling and protecting the electrical circuits and equipment is known as switchgear. This is very basic definition of switchgear.
