According JGJ142-2004 "floor radiant heating technology point of order", referring to GB / T17657-2013 "panels and veneer plywood physical and chemical properties of test methods" in clause 4.60, to simulate the actual use of geothermal floor, the test temperature is from 23 ℃ up to 50 ℃. In this testing procedures, pvc playground border Philippines sampling from 21 producers in 24 batches of complex geothermal floor samples (parquet 12 batches, 12 batches of laminate flooring), there are 19 batches of formaldehyde measured value exceeds the reference value, excessive rate of nearly 80 percent. Shanghai quality supervision analysis, excessive formaldehyde mainly from the following aspects: First, corrosion-resistant fence post lighting formaldehyde adhesive laminate flooring not participate; Second, the production process of formaldehyde release; Third, environmental temperature and humidity affect the course of that, the cured layer aging degradation emit formaldehyde.

During 315, Zhejiang Consumer Protection Committee The results also showed that: 87% of the flooring in a simulated environment geothermal formaldehyde In fact, early in the Shanghai Quality Supervision released before "risk warning," during the 2015 315, commissioned Consumer Protection Committee of Zhejiang Province,Cheap Vinyl Fencing Panels for Swimming Pools Zhejiang Institute of furniture and hardware, also carried out to warm the floor formaldehyde emission comparison test, and draws The same grim results. The test results show that Zhejiang Consumer Protection Committee: 15 normal qualified composite geothermal dedicated floor, at 40 ℃ environment, there are 13 batches of formaldehyde emission exceeded the national standard, accounting for 87%, an increase of between 4 to 30 times .

Comprehensive Test Results of Zhejiang and Shanghai as quality supervision agency, can say with certainty that the current commercially available compound to heat the floor if it is used to heat,decks on second floor with covered patio below the prevalence of the risk of formaldehyde, and the value exceeded shocking. In addition to calling the relevant departments as soon as possible formaldehyde define standard geothermal environment dedicated floor, and the strict enforcement of protection of health, the geothermal users the most effective way is possible to buy pure solid wood to heat the floor, pushing home health progress with the power consumption decisions.
