The quality of floor leather is related to the manufacturer and brand. Regular manufacturers have advanced production technology and guaranteed quality. The product is qualified and has no obvious harm to human body. Some floor leathers are backward in processing technology, mostly bonded by adhesives, or lead content exceeds the standard, which is harmful to health.
Methods for judging the quality of floor leather;
1. odor: does the product have a chemical odor that irritates people? The strong smell is likely to be that the limit of harmful substances exceeds the standard or that the printed layer on the surface of floor leather releases toxic gases.
2. Look: whether the floor leather is full in thickness, whether the bottom foam layer, printing layer and wear-resistant layer are layered, whether there is a bottom layer, whether the bottom layer is as thick as cicada wings, and whether the back of the floor leather is black.
3. Trial: For thin floor leather, you can tear it by hand. If it can be easily torn off, the tearing strength of floor leather will not meet the requirements. If the floor leather is gently rolled up and pressed, if it cannot be restored to its original state, leaving an indentation, the softness of the product will be very poor. If several layers can be torn by hand, it means that the interlayer combination of the product is not good, and delamination will soon occur in future use.
Moreover, according to the spot check of AQSIQ, the main quality problem of floor leather is that the lead content exceeds the standard, and lead dust is easy to form indoors during use and wearing.
Therefore, if you can smell the obvious pungent smell of floor leather, it is harmful. You'd better choose better floor leather to use, and often open the window for ventilation during use to keep the indoor air unobstructed. You can also put some activated carbon and flowers indoors.
