The decoration of a new home should be full of joy and expectation, but in recent years, incidents such as "getting sick when you move into a new house" have been frequently exposed, making moving to a new home also a person who loves and fears. Why is this happening?A large number of facts tell us that the problems caused by decoration pollution are very serious.
According to the statistics of household air test results in the past 3 years, the indoor air formaldehyde excess rate of residential buildings more than 6 months after renovation is still more than 57%, and even after one year of decoration, the formaldehyde excess rate is still nearly 40%.
The problem caused by decoration pollution is so serious, yet most consumers are in the "drug den" without knowing it. Experts have found that there are more than 500 volatile organic compounds in indoor air, including more than 20 carcinogens and more than 200 pathogenic viruses. The main hazards are: formaldehyde, benzene, ammonia, esters, trichloroethylene, etc.
A large number of shocking facts have confirmed that indoor air pollution has become the "killer" that endangers human health, and has also become a common concern of all countries in the world. Studies have shown that indoor air pollution is 2-5 times more severe than outdoor air, and in special cases can reach 100 times.
As one of the main materials in home decoration, its environmental protection also affects the health of the whole family, so families who have requirements for home decoration health must be more cautious when choosing plates. The state also has standards for the amount of formaldehyde released in wood-based panels and their products, which is pointed out in a new environmental protection standard issued on October 1, 2021, that the formaldehyde emission standards of boards are divided into E1 grade, E0 grade, and ENF grade, which are tested under 23 conditions. We know that the amount of formaldehyde released is affected by temperature, and as the temperature increases, the amount of formaldehyde released will also increase.
In order to enable consumers to use more environmentally friendly and healthy boards, Sanshan Wood took the lead in formulating the standard of "Formaldehyde Emission Limit in Heating Wood-based Panels and Their Products". The standard stipulates the formaldehyde emission standard of indoor wood-based panels and their products in a high temperature environment of 30, and the formaldehyde emission of indoor wood-based panels and their products in the heating environment is divided into three grades according to the limit value: HE1 grade (0.).124 mg M), HE0 grade (0050 mg M) and henf grade (0025mg/m³）。The development of this standard aims to ensure the environmental performance of the board and provide consumers with a healthier and safer living environment.
When the indoor temperature exceeds 23, the formaldehyde molecule gains more energy and becomes more active, resulting in an increase in its release. This makes the formaldehyde concentration in the indoor air significantly higher, and may even seriously exceed the standard. Therefore, the environmental protection standard of a single board does not represent the environmental protection status of the entire space environment. When the floor, wardrobe and other furniture in the entire indoor space are in a high temperature or heating environment, the amount of formaldehyde released will increase significantly, causing great harm to people's health.
It is worth mentioning that the standard temperature difference between ENF and HEHEN levels for formaldehyde detection is 7, and this temperature difference will lead to a 2-3 times difference in formaldehyde emissions. Therefore, consumers should pay more attention to whether they meet the HENNF level standards when choosing man-made panels and their products.
Choosing man-made panels and their products that meet HEFF standards will help reduce the level of formaldehyde pollution in indoor air and provide a healthier and more comfortable living environment for family members. The HEN-level board represented by Sanshan meets the HENN-level standard, and it is undoubtedly a wiser choice for families who pursue high environmental protection standards to choose the HENN-grade re-kang board.
Compared with the national standard ENF level standard tested under 23, the formaldehyde emission detection was carried out under the condition of 30, and the emission was controlled at 0025 milligrams per cubic meter to ensure that it meets the strict requirements of the HENN environmental protection level. This high environmental protection standard makes Rekang board unique in the board industry, and truly becomes a leader in the field of environmental protection.
Rekang board is a board that purifies harmful substances such as formaldehyde and TVOC of wood-based panels and veneered wood-based panels by using high-temperature heat treatment and purification technology, which is called a new type of health board for heat treatment purification, referred to as Rekang board.
The uniqueness of the HENNF-level thermal plate lies in its special heat treatment and purification process. The process is able to put artificial.
Formaldehyde, TVOC and other harmful substances in panels and veneered wood-based panels are "clean". Studies have shown that the volatilization rate of formaldehyde and VOCs will be greatly accelerated at high temperatures. It is this feature that the HENNF grade thermal board takes advantage of this feature to heat treat and purify the board at a high temperature of more than 100 degrees to ensure the removal of harmful substances such as free formaldehyde, uncured formaldehyde, TVOC, bacteria and viruses. After three heat treatment processes: "dry heat, damp heat, wind heat", that is, "baking, steaming, baking", the rekang board has reached the real harmless standard.
In the actual decoration and use, whether it is in the environment where the geothermal heat is as high as 50, or in the summer environment when the room temperature is about 30, the use of HENF-level thermal board can greatly reduce the emission of formaldehyde and TVOC, which is more than 60% less than that of ordinary boards. Users can use it with confidence and no longer worry about the problem of exceeding the standard of harmful substances. Therefore, the HENNF-grade thermal board is more suitable for families with high environmental protection requirements for decoration.
