LVT/SPC/WPC Floor Knowledge Little Science

The main component is polyvinyl chloride material. PVC flooring originated in Europe and the United States, and is very popular in Europe, America and Asia-Pacific. China currently has more 2.0MM commercial flooring, and SPC and WPC flooring are also slowly spreading.

Several common expression methods of plastic floor

1 PVC: poly vinyl chloride

2 LVT: luxury vinyl tile

3 LVP: luxury vinyl plank

4 Vinyl floor

5 Vinyl plank

6 WPC: wood plastic composite

7 SPC: stone plastic composite

European and American countries call this kind of floor RVP (rigid vinyl plank), rigid plastic floor.

Second, the classification of plastic flooring

At present, PVC sheet flooring can be made into two types, one is the same texture and the floor is the same from bottom to surface. If the surface is burned or scratched, it can be repaired with a waxing machine. . The other is that the top layer is a pure PVC transparent layer, and then the printing layer and the foaming layer are added below. It can be seen that the same quality penetrating material is much superior to the composite type.

From the morphological point of view, it is divided into coiled floor and sheet floor; the products highlighted in this article: LVT, WPC floor belongs to semi-rigid sheet plastic floor, and SPC (RVP) floor belongs to hard sheet floor. At present, there are three main types of LVT flooring: vinyl locking, dry back, loose lay. From another perspective, PVC flooring can be divided into: (Dry Back) click (Loose lay) according to the assembly method. At the same time, WPC wood-plastic flooring and SPC stone-plastic flooring are also in the stage of active promotion and rapid development in domestic and foreign markets.

3. The composition of the plastic floor

PVC floor composition: PVC resin powder, stone powder, stabilizer, internal and external lubricants, ACR, CPE, carbon black, etc. The main components are polyvinyl chloride and stone powder.

Plastic floor is composed of backing layer, core layer, glass fibre, decorative paper and wear layer in order from bottom to surface.

4. PVC certification

At present, the certification of PVC products are Floor score, DIBT, CE, ISO14001:2004 and ISO9001:2008, TÜV Rheinland.

V. The most critical product indicators of PVC

• Stability: Product shrinkage and expansion rate 80 ℃ 6 hours. 0.25%, 0.15% (standard)

• Warpage during heating: 80℃ 6 hours EN<2mm; Enterprise standard: 1.2mm(dryback); 1.0mm(click); 0.5mm(loose lay)

• Locking tension: normal temperature (23℃) 5.0mm>13-15kgs/5cm, 4.2mm>12kgs/5cm, if the short side uses V buckle, 4.2mm>15-18kgs/5cm.

• Peeling strength: the strength of the color film and the intermediate material, which is also a small skill to judge the new material, anti-scratch and wear-resistant.

• Brightness: 10+/-2.

6. Calculation of floor purchase area:

1. If the area to be paved is 50 square meters, because a part of the floor to the corner needs to be sawed off, and the loss rate of the general floor is 5%, the actual area is 50*(1+5%)=52.5 square meters.

2. Advantages and disadvantages of LVT flooring

advantage:

1. Green and environmental protection

The main raw material for the production of PVC flooring is polyvinyl chloride. Polyvinyl chloride is an environmentally friendly and non-toxic renewable resource. It has been widely used in people's daily life, such as tableware and medical infusion tube bags. Its environmental protection is not necessary. worried.

2. Super wear-resistant

There is a special PVC wear-resistant layer on the surface of PVC floor. According to the difference in wear-resistant thickness, it can be used for 5-10 years under normal conditions. The thickness and quality of the wear-resistant layer directly determine the use time of PVC flooring. The standard test results show that the ground of 0.55mm thick wear-resistant layer can be used under normal conditions. Used for more than 5 years, the ground with a 0.7mm thick wear layer is sufficient for more than 10 years, so it is super strong and wear-resistant. Because of its super abrasion resistance, PVC flooring is becoming more and more popular in hospitals, schools, office buildings, shopping malls, supermarkets, transportation, and other places with large traffic. (For the wear resistance of the wear layer, at present, it is mainly through the loss measurement, that is, the quality reduction as an indicator)

3. High elasticity and super impact resistance

The texture of PVC floor is soft, so the elasticity is very good. It has good elastic recovery under the impact of heavy objects. At the same time, PVC floor has strong impact resistance, and it has strong elastic recovery against heavy impact damage, and will not cause damage. Excellent PVC flooring can minimize the damage of the ground to the human body and can disperse the impact on the feet. The latest research data shows that after the excellent PVC flooring is paved in a space with a large flow of people, its personnel fall And the rate of injuries is reduced by nearly 70% compared to other floors.

4. Fire retardant

The fire protection index of qualified PVC floor can reach B1 level, which means that the fire performance is very good, second only to stone. Fire is extinguished.

5. Easy maintenance

The maintenance of the PVC floor is very convenient. If the ground is dirty, wipe it with a mop. If you want to maintain the lasting and shiny effect of the floor, you only need to wax regularly for maintenance, and the number of maintenance is much lower than that of the laminate floor.

6. Waterproof and moisture proof

Since PVC flooring is mainly composed of vinyl resin and has no affinity with water, it is naturally not afraid of water, as long as it is not immersed for a long time, it will not be damaged; and it will not be moldy due to high humidity.

2 disadvantages:

Non-natural materials and high requirements for the base floor (the base layer must be flat, solid and dry when the LVT floor is laid, the surface of the plastic floor is smooth, the corners of the yin and yang are square, no edges, no oil stains, dust and impurities).

3 WPC floor WPC

WPC combines the waterproofness and stability of LVT and is also easy to install like laminate flooring.

With the addition of cork and EVA pads, the foot feel and sound insulation will be better than the LVT lock floor.

WPC uses environmentally friendly materials, which are more environmentally friendly than laminate flooring.

In short: WPC has the advantages of both LVT and Laminate.
