Be careful to cause formaldehyde to release a quantity to exceed the standard

In the winter, many consumers in the home to install geothermal heating. But whether it can withstand the test of temperature to warm the floor? On the 14th, Guizhou Province quality and Technical Supervision Bureau in its official website issued by 2016 wood flooring products quality risk early warning display, aggrandizement wood floor, solid wood flooring, multi-layer solid wood flooring heating ubiquitous formaldehyde to release a quantity to exceed the standard, even if is the nominal geothermal floor.
According to reports, in order to evaluate enhanced wood floors, wood composite floors, geothermal floor products quality and safety, Guizhou Province Bureau of quality and technical supervision organization on the floor to carry out quality and safety risk monitoring samples from Guizhou Province building materials products market is collected. The risk monitoring based on the GB18580-2001 "interior decoration decoration materials and products in the formaldehyde release limit". The formaldehyde emission of the floor above 20 C (standard condition) and 50 C (under Simulated Geothermal Conditions) was detected.
The risk monitoring of a total of 20 batches of samples were collected, including 15 batches of laminate flooring, 3 batches of solid wood flooring, 2 batches of geothermal floor. The standard test temperature at 20 degrees Celsius, 3 batches of laminate flooring formaldehyde emissions exceeded, the problem product detection rate was 15%. The test temperature from 20 to 50 after the test of 20 batches of samples, 20 batches of samples are not in line with the national standard of formaldehyde release limit, the problem product detection rate of 100%.
Formaldehyde release amount exceeded the main reason is in production to strengthen wood flooring, solid wood flooring, multi-layer solid wood flooring process, joined the amount of adhesive and preservatives, with adhesive and preservatives containing different levels of formaldehyde, into the product, floor in the middle of the hot pressing process points of cleavage of ether bond will release formaldehyde, and with the increase of environmental temperature, formaldehyde to release a quantity to will increase, leading to the increase of concentration of formaldehyde in indoor air. Formaldehyde is a colorless, strong irritant gas at room temperature, volatile, has been the World Health Organization to determine as carcinogenic and teratogenic substances, is a potential strong mutagenicity of.
So when wooden floor into the warm, be careful of formaldehyde to release a quantity to exceed the standard, formaldehyde to release a quantity to exceed the standard, for the Green League environmentally friendly indoor air formaldehyde governance experts, picked up your side of the phone. A key to solving your side of formaldehyde pollution problems.
