Three new types of floor: LVT floor /SPC floor /WPC floor difference.
One, LVT floor
1. LVT floor structure: the internal structure of LVT flooring generally includes UV paint layer, wear-resisting layer, color film layer, LVT base material layer, general base material for three LVT composite together. In order to improve the dimensional stability of the floor, the customer will ask the factory to add fiberglass mesh in the middle and bottom material layer to reduce the deformation of the floor caused by temperature changes.
2. Main ingredients of LVT floor: PVC resin, stone powder, plasticizer, stabilizer, lubricant, modifier, carbon black, etc., which are mainly PVC resin and stone powder.
3. LVT floor production process: the biggest feature of the production process is the production of LVT sheets of each layer, which are generally processed into 0.8~1.5mm thick sheet by means of "compact + calendered", and then made into the required thickness of floor products by means of forming billets and hot pressing.
Two, WPC floor
1. Structure of WPC floor: as shown in the figure, WPC floor includes paint layer, wear-resistant layer, color film layer LVT layer and WPC substrate layer.
2. Composition of WPC floor: the main composition of WPC floor is similar to that of LVT floor.
3. WPC floor production process: as can be seen from the product structure diagram, WPC floor is a composite floor including LVT and WPC substrate. Its technological process is, first made into a single-layer structure of LVT floor, and then extruded WPC substrate with adhesive pressure paste composite molding, the adhesive used for polyurethane type cold pressure adhesive.
Three, SPC floor
1. SPC floor structure: currently, there are three types of SPC floors on the market: single SPC flooring with online laminate, SPC composite AB structure with LVT and SPC and SPC composite SPC floor with ABA structure. The following figure shows the single SPC floor structure.
2. Main ingredients of SPC floor: it is also a PVC floor product, and its main raw materials are basically the same. Different from LVT floor, the base material of SPC floor is added with lubricant in the production process, so as to complete extrusion more smoothly.
3. SPC floor production process: similar to WPC floor substrate, SPC substrate is extruded and rolled into sheet plate by extrusion machine, and then affixed with composite film and wear-resistant layer on the surface. If the SPC composite floor is AB or ABA structure, the SPC substrate shall be extruded first, and the LVT layer shall be pressed and pasted by means of group blank compound.
Above is the difference of LVT floor, WPC floor, SPC floor, these 3 kinds of new floor, also be the derivative of PVC floor actually. Because material of these 3 kinds of new floor is special, apply more extensive than wooden floor, in euramerican market extensive popularity, domestic market still waits for popularity.
