SPC lock flooring is a kind of sheet floor, its main raw material is also polyvinyl chloride, SPC lock flooring is made of polyvinyl chloride (divided into pure new material, mixed material, recycled material), calcium powder (different grades are also available) The grade of stone powder) and solvent (some use chemical grade and some use vegetable solvent food grade) are subjected to high temperature pressing and hot compressing color film, pvc wear-resistant layer, and after cooling treatment, they are subjected to uv process (determining the anti-fouling performance of the floor and the sun's ultraviolet radiation). No discoloration performance), the final floor cutting and grooving process (partially determines the floor lock strength and bearing tension), and finally boxed and packaged.

Next, let's talk about three misunderstandings of SPC lock flooring

1. The flame retardant of SPC lock flooring is not unburnable

If you have to use a lighter to burn the SPC lock flooring, see if you can burn it. If it burns, it is not fireproof. In fact, the state requires the fire rating of SPC lock flooring to reach the standard of Bf1-t0. According to the national standard, non-combustible materials are rated as fire class A, such as stone and brick. The technical content of the Bf1-t0 flame retardant standard is a cotton ball with a diameter of 10mm, dipped in alcohol, and placed on the PVC floor to burn naturally. After the cotton ball is burned out, measure the diameter of the burnt SPC lock flooring trace. If it is less than 50mm, it is the Bf1-t0 flame retardant standard, rather than burning it. Class B fire protection usually means that it will not continue to burn away from the fire source.

2. The wear resistance of SPC lock flooring does not mean that it will not be scratched with a sharp tool

When asking about the service life and wear resistance of the SPC lock flooring, take out sharp tools such as a knife or a key, scratch the surface of the SPC lock flooring, and if there are scratches, it is considered not wear-resistant. In fact, the country's test of the wear resistance of the SPC lock flooring is not simply to scratch the surface with a sharp tool, but to use a flat-bottomed circular grinding disc to grind the test floor under the condition of 1Kg pressure. After rotating and grinding how many turns, the floor surface The number of revolutions at which the wear layer is worn to expose the base layer. The number of revolutions of this node is an indicator to measure the wear resistance of the SPC lock flooring. For example, the national minimum standard for the number of revolutions of laminate floors is 1500 revolutions. Generally, 0.3mm wear-resistant SPC floor can reach 8000-1000 revolutions, so the wear resistance of PVC floor is specially measured by the national testing agency.

3. Smell with the nose is not unfriendly to the environment

The SPC lock flooring itself is formaldehyde-free, and the SPC lock flooring is not allowed to use formaldehyde in the production process. AJFLOOR's SPC lock flooring should be 100% formaldehyde-free, and there may be fragrances and auxiliaries. Smell, will not cause harm to people's body, and will not make people feel uncomfortable.

If you smell the floor, a large part of the reason is the use of EVA mute pads. A large part of the EVA mute pads on the market will have a more or less smell. If you want to eliminate this problem, you can choose IXPE silent pad or SPC floor without silent pad.
