Formaldehyde testing
Polyvinyl Chloride Flooring environmental protection of the most important standard is formaldehyde emissions. A wake up the release of standard qualification, the flooring industry environmental protection has experienced a total of E1, EO, FCF three technical revolutions.
At an earlier stage, the wood-based panel of the formaldehyde emission standards for the E2 level (formaldehyde emission ≤ 30mg/100g),the release of its A wake-up limit is very loose, even if it is reduced to 0.5mg/L, even if the composite of this standard product, the formaldehyde content may also exceed the E1 level, a serious danger to human health.
So there is a first environmental revolution, in this environmental revolution, the flooring industry to implement E1-level environmental standards, that is, formaldehyde emissions ≤ 1.5mg / L, although the human body basically does not yet pose a threat, but the floor is still left with many free formaldehyde.
In 2009, the flooring industry has begun a second environmental revolution, the introduction of E0-level environmental standards, is the floor formaldehyde emissions reduced to 0.5mg / L.
However, PVC Flooring is composed of natural materials such as PVC and calcium carbonate powder, there is no formaldehyde, and most of the Polyvinyl Chloride Flooring is processed from virgin materials, the entire production process did not participate in any harmful substances.
More accurately should be a strong odor of PVC Flooring is not environmentally friendly. Polyvinyl chloride material itself does not contain formaldehyde, polyvinyl chloride flooring in the production process will not use any formaldehyde-containing products, qualified polyvinyl chloride flooring should be 100% free of formaldehyde release, there may be aromatics and additives to the odor, will not cause harm to people’s bodies, and will not make feel uncomfortable.
Fire Test
According to the laboratory standard non-combustible materials are designated as fire resistant class A, such as stone and tile. Laboratory on Polyvinyl Chloride Flooring fire rating requirements to meet the standards of B1 level, B1 level flame retardant standards; B1 level test
method is: with an inner diameter of 10mm cotton balls, dipped in alcohol, placed on the surface of the Polyvinyl Chloride Flooring natural combustion, the cotton ball burned out, measure the diameter of burned floor traces, such as less than 50mm, is the B1 level of flame retardant standards.
Abrasion test
Laboratory abrasion resistance test of PVC flooring is a flat-bottomed garden grinding disc, under pressure 1Kg grinding test floor, in the rotating sanding how many revolutions, the floor surface wear layer is worn to reveal the number of revolutions of the grass-roots level.
The number of revolutions of this node is a measure of the wear resistance of Polyvinyl Chloride Flooring an indicator.
