PVC floor overview


PVC flooring is made of polyvinyl chloride and its copolymer resin as the main raw materials, adding fillers, stabilizers, lubricants, plasticizers, colorants and other auxiliary materials, and producing into sheets through the processes of compounding, extrusion, banburying, and calendering. On the continuous substrate, the following different processes are selected according to different products: coating, laminating, gluing, hot pressing, tempering, cutting, etc.


Products are hard and semi-hard products.

Common terms for PVC flooring: PVC LVT / WPC / SPC, etc.


Several expressions of PVC floor


Vinyl Floor/Plank vinyl floor;

LVT (luxury vinyl tile): luxury vinyl floor tiles; LVP (luxury vinyl plank): luxury vinyl floor;

WPC (wood plastic composite): wood-plastic composite material. Bamboo and wood powder are added to the formula. However, after adding bamboo and wood powder, it is difficult to process and recycle. At present, there are few or no WPC floor substrate formulations. Add wood flour. (The resin can be materials with a melting point lower than 230°C, such as PE, PP and PVC)



SPC (stone plastic composite): Stone plastic composite material, called RVP (rigidvinyl plank) in Europe and America, rigid plastic floor. (The resin can be PE, PP, PVC, ABS, etc.)


PVC floor characteristics


Due to its superior performance and environmental protection, PVC flooring has generally replaced ceramic tiles and wood flooring in European and American countries, and has become the most commonly used and popular variety in flooring. It is the first choice for floor decoration materials and has a very broad development prospect.


Green and environmental protection: Polyvinyl chloride is a 100% new environmentally friendly and non-toxic resource. The raw materials are non-natural materials, which do not damage forest resources and formaldehyde;

Super wear-resistant: There is a transparent wear-resistant layer on the surface of the PVC floor, and its wear-resistant speed can reach T level. The 0.55mm thick wear-resistant layer can be used for more than 5 years under normal conditions, and the 0.7mm thick wear-resistant layer The ground is sufficient for more than 10 years, so it is super wear-resistant. Tongtou floors are generally guaranteed for 20 years. The wear resistance of PVC depends on the thickness of the wear layer, which can generally be used for 5-10 years.

Antibacterial performance: The surface of the PVC floor has undergone special antibacterial treatment, and the surface of the PVC floor has also been specially added with antibacterial agents, which have strong killing ability for most bacteria and the ability to inhibit bacterial reproduction;

Fireproof and flame retardant: The fireproof index of qualified PVC floor can reach B1 level, which means that the fireproof performance is very good, second only to stone. PVC floor itself will not burn and can prevent burning;

Waterproof, moisture-proof and mothproof: As the main component of PVC floor is vinyl resin, it has no affinity with water, so it is naturally not afraid of water. As long as it is not soaked for a long time, it will not be damaged, and it will not be mildewed due to high humidity. termite;

Sound absorption and anti-noise: PVC floor has a sound absorption effect that cannot be compared with ordinary ground materials. Its sound absorption can reach 20 decibels. Therefore, you will never choose PVC floor in quiet environments such as hospital wards, school libraries, lecture halls, theaters, etc. You need to worry about the impact of high-heeled shoes and the ground knocking on your thinking. PVC flooring can provide you with a more comfortable and more humane living environment.

Variety of patterns and colors : There are many patterns and colors of PVC flooring, such as carpet pattern, stone pattern, wood floor pattern, etc. The patterns are realistic and beautiful, with colorful attachments and decorative strips, which can combine to create a beautiful decorative effect.

Acid and alkali corrosion resistance: PVC floor has strong resistance to acid and alkali corrosion, can withstand the test of harsh environments, and is very suitable for use in hospitals, laboratories, research institutes and other places.

Convenient maintenance: The maintenance of PVC floor is very convenient. If the floor is dirty, wipe it with a mop. If you want to maintain the long-lasting bright effect of the floor, you only need to wax it for maintenance regularly, and the maintenance frequency is much lower than other floors.

Related certification system

Currently, the certification of PVC products includes Floorscore, DIBT, CE, ISO14001:2004 and ISO9001:2008, TÃœV Rheinland, etc.

PVC classification and process


classification


There are two types of PVC flooring: one is homogeneous permeable flooring (semi-hard), and the other is multilayer composite flooring (hard and semi-hard).

From the morphological point of view, PVC multi-layer composite flooring is divided into coil flooring and sheet flooring; LVT and WPC flooring are semi-rigid sheet plastic flooring, and SPC (RVP) flooring is hard sheet flooring. According to the assembly method, it can be divided into: ordinary (Dry Back, installation requires glue, low price), click (click) and glue-free (Loose lay, relatively soft). At present, SPC stone plastic flooring and WPC wood plastic flooring are also in active promotion and rapid development in domestic and foreign markets.

PVC composite floor


â‘´ LVT floor (semi-hard):

[Constitution] : ① UV treatment layer: bright, stain-resistant and protective; ② PVC transparent wear-resistant layer: super abrasion resistance and impact resistance; ③ color film layer; ④ (glass fiber mesh): strengthening and dimensional stability; ⑤ The middle layer: dimensional stability; ⑥ the bottom layer: elastic cushioning, sound absorption and improving foot feel (generally PVC, cork or EVA foam).


[Technology] : 1. Base material, intermediate material (mixing, banburying and calendering); 2. Hot pressing (pressing), static curing; 3. UV roller coating, tempering, static curing; 4. Punching Cut and leave to keep in good health; 5. Edge trimming or slotting; 6. Packaging;


⑵ WPC floor (hard): LVT layer (semi-hard) + WPC (hard) layer gluing

[Composition] : ① UV treatment layer: bright, stain-resistant, and protective; ② transparent PVC wear-resistant layer: super abrasion resistance and impact resistance; ③ color film layer; ④ (glass fiber mesh: reinforcement and dimensional stability); ⑤ Intermediate layer: LVT layer (thin, generally about 1.5 mm); ⑥ WPC layer (thick, generally 4-6 mm, low foaming). ⑦ Bottom material layer: elastic buffer, sound absorption and improve foot feel (generally PVC, cork or EVA foam).


[Process] : 1. Base material, intermediate material (mixing, banburying, extrusion and calendering); 2. Gluing (LVT layer and WPC layer); 3. UV roller coating, tempering; 4. Punching; 5 . Sharpening or slotting; 6. Packaging;

        

⑶ SPC floor (hard):

[Composition] : â‘  UV treatment layer: bright, stain-resistant, and protective; â‘¡ transparent PVC wear-resistant layer: super abrasion resistance and impact resistance; â‘¢ color film layer; â‘£ stone plastic layer.


[Process] : 1. Mixing; 2. Extrusion; 3. Calendering thickness; 4. Filming: color film→sticking wear-resistant layer; 5. Cutting; 6. UV treatment (coating and tempering), 7 . Slitting → grooving, trimming, chamfering → inspection → packaging.

Differences between SPC and WPC


â‘´ SPC production process is simpler, lower cost, hard product.

⑵ SPC is more stable in size, more resistant to heat and cold, and can be used for floor heating. SPC floor is suitable for indoor spaces from extremely cold (-20°C) to extremely hot (60°C). There is a risk of deformation when the WPC floor is indoor temperature below 0°C;
