Today the market is a variety of decoration materials, flooring materials are also based on their own needs to choose, the current more popular PVC flooring, but most people still have relatively little understanding of it, many people are concerned about the issue of whether the stone plastic flooring contains formaldehyde, harmful, etc. I came to give you a science of whether the stone plastic flooring is harmful.
The main materials of polyvinyl chloride flooring are: polyvinyl chloride resin powder, stone powder, stabilizer, plasticizer, carbon black floor.
Environmental protection non-toxic three elements: heavy metals, plasticizer, formaldehyde.
1. Heavy metal:New resin powder does not contain heavy metal. If the floor is processed with recycled materials (plastic waste, medical waste, construction waste), heavy metals will certainly be seriously over the limit.
2. Plasticizer: ordinary cheap plasticizer for the phthalate structure (DOP), the plasticizer produces phthalates and other 10 kinds of harmful substances, carcinogenic benzene structure (DOTP) plasticizer price is much higher, is the most environmentally friendly, non-toxic and harmless plasticizer in the field of plastics, eliminating the collar benzene dicarboxylate.
3. Formaldehyde: Formaldehyde is widely present in adhesives and is unavoidable. As long as there is glue, there is formaldehyde. So if the PVC flooring of the backing is formaldehyde, compared to the locking flooring does not contain formaldehyde.
Whether a PVC floor is toxic or not therefore depends on the raw material used.
The name PVC stone flooring is easy to cause misunderstanding, the market also known as "SPC stone flooring", mentioned PVC more people will think of plastic, harmful to the human body. But PVC stone flooring and plastic is not the same thing at all, PVC can also be called PVC, PVC is environmentally friendly non-toxic renewable resources, it has long been used in a large number of people's daily life, such as tableware, medical infusion tube bags, etc., its environmental protection is not to worry about.
The main component of PVC stone flooring is natural stone powder, making it a green and environmentally friendly new flooring material. SPC flooring is 100% free of formaldehyde, benzene and other toxic substances, no radiation, belongs to the environmental protection decorative materials, will not cause any harm to the human body.
SPC stone plastic flooring due to its unique advantages and broad development prospects, many enterprises have also begun to involve in the SPC stone plastic flooring industry, through the introduction of equipment, technology and other aspects of innovation, SPC stone plastic flooring substrate has been a long development, and has begun to involve in the SPC stone plastic flooring industry.
At present, the substrate used by domestic manufacturers can be broadly divided into two kinds of new materials and recycled materials.
The quality of stone plastic flooring produced using recycled materials is far inferior to that of stone plastic flooring using virgin materials. Quality substrate stepped on strong elasticity, soak water is not easy to deform, hot and cold is not easy to shrink, the use of a long time will not appear edge warping, and health and environmental protection, non-toxic harmless;.
However, substrates made from recycled materials are barely resilient and will swell significantly when immersed in water, causing warped edges. If the temperature drops too quickly in winter, there will be significant shrinkage, thus affecting the aesthetics of the floor, and the quality of recycled materials hides a huge amount of toxic damage. So we advise consumers to buy virgin products and never lose out on a small price!
