Environmental performance of pvc sheet

Environmental protection performance of pvc sheet:

Mold growth test: Use mold strains to release on the sample to investigate the degree of mold reproduction during exercise. Experimental results: LG flooring can inhibit the growth of mold for a long time, and the prevention of mold can reach a zero level.

PVC elastic floor is an environmentally friendly floor that is harmless to people and the environment. The surface UV treatment layer adds natural silver to make the PVC floor have a two-layer antibacterial layout (the original technology of LG Chem). Other floors are produced due to the use of glue. Avoid a certain amount of formaldehyde (currently 100% of domestic PVC flooring products are rich in formaldehyde and have a flushing smell), and LG elastic flooring has a formaldehyde content of 0.

Formaldehyde release test: the impact of released amount (mg/L) on human body

0.5-1.5 Human nervous system impact

1.5-2.0 Itchy eyes, insomnia, etc.

2.0-30 Effects of trachea and lungs

30-100 Emphysema, pneumonia, other inflammations

More than 100 direct death

The test results are 1.5 for laminate flooring, 2.7 for composite flooring, 2.6 for domestic PVC flooring, and 0 for LG flooring.

Antibacterial function test: choose the film compaction method to test, place the publicized bacteria (E. coli, pneumoniae, subtilis B) on the experimental floor, 24 hours later, separate the calculation test to guess the number of bacteria reduction, and the quota indicates its sterilization ability .

Experimental results LG floor E. coli sterilization 98%, pneumonia bacteria 100%, subtilis B 97%, other floors can only be 25%/30%/23%.
