Every summer is always a busy month for the sports flooring industry.
The manufacture vigorously increases its output.
The construction team rushed to work overnight to shorten the construction period.
The testing agency investigates the materials to ensure safety.
A primary school project in Chifeng City, Inner Mongolia
Sampling conditions:
Cut samples and submit them for inspection on the second day after construction
(Generally speaking, the cast-in-place floor material needs to be allowed to stand for a week after the construction is
completed to fully complete the reaction in order
to obtain high-quality physical and chemical properties)
Before the formal acceptance, the inspection report issued by China National Inspection and Quarantine Group and the National Building
Materials Testing Center.
Inspection document publicity:
The inspection is carried out by the National Research Center of Testing Techniques for Building Materials.
Confirmed to pass the new national standard test.
Low release of hazardous materials
Excellent measured data
On-site cutting sample
The new national standard test is short and difficult, and puts forward strict requirements on JRace solvent-free products: cutting samples immediately after the completion of the construction.
The on-site cut samples are measured after follow-up testing:
The TVOC release rate: m^2·] is far less than the new national standard requirement ≤m^2·]
Odor level: Level 3 requirements.
The content of inorganic filler is 65% according to the new national standard.
Conclusion:
TVOC is the release of volatile hazardous substances, and generally shows a stable value one week after the completion of the running track construction.
In this inspection, it was inspected immediately after construction.
It can be considered that the TVOC detected at this time is the maximum value of the runway data.
The test value of 1.6 means that JRace products can pass the TVOC test smoothly.
The smell level breaks through the market common level of the traditional new national standard product level 3, reaching level 2.5.
In the inorganic filler test, the detected value is 46.8%. It is much lower than the upper limit of 65% of the new national standard.
The experiment proves that JRace products have a high glue content
(high glue content can be cited as the long service life of the product, and the raw materials are produced with relatively high-quality good materials)
Summary:
JRace’s solvent-free series products can successfully pass the strict inspections of the new national standard without fear of on-site inspections.
