What is SPC flooring?
SPC stands for stone plastic composite (or stone polymer composite).
SPC flooring is an upgrade and improvement of regular luxury vinyl tiles (LVT), the main content of SPC are natural limestone powder, polyvinyl chloride and stabilizer which combined by a certain ratio to provide us a very stable composite material.
SPC flooring is considered the new generation of floor covering, its features: extremely stability, good performance, completely water-proof, high density solid core, indentation resistance;
It can be easily installed on different types of floor base, either concrete, ceramic or existing flooring;
It’s formaldehyde free, completely safe flooring covering materials for both residential and commercial area.
SPC core is typically comprised of around 60% calcium carbonate, 20% polyvinyl chloride and 20% other plasticizer chemical materials.
The structure of the SPC floor, from top to bottom are UV layer, Wear resistant layer, PVC decor film, SPC core, and EVA/ IXPE underlay.
Full production processes of SPC flooring
1. Crushing + Milling
During the SPC production process， it will generate some fragment waste materials. The Crusher and Miller can be used to crush and grind these SPC waste materials into powder, which can be recycled into the raw materials for the production of SPC. The recycled SPC material is also a necessary ingredient in the raw material ratio.
2. Mixing
Put the raw materials into a high-speed mixer for hot mixing according to a certain ratio, so that the various materials are mixed uniformly, and the moisture in the materials is removed, and then enter the cold mixer to cool the materials to prevent agglomeration and discoloration. The materials are mixed uniformly by cooling.
3. Extrusion
The mixed materials are put into the extruder, extruded by twin cone screw, and formed into sheet shape through the die. Then through four-roller/five-roller calendering unit, the wear-resistant layer and color film are laminated on the sheet by heat, to form the SPC board.
4. UV coating
A layer of UV paint is coated on the surface of the SPC board by the UV coating machine, which has the functions of preventing dust, scratching, increasing abrasion resistance, and making the glossy more uniform.
5. Cutting
Use automatic multiple ripsaw to cut the big SPC board into the small planks of the required size.
6. Slotting
Through the longitudinal and transverse double-end tenoner slotting machine, four sides edges of the SPC plank after cutting are processed into certain lock shape. The important thing is that need to choose the suitable click system and the perfect Polycrystalline diamond (PCD) click profiling cutters.
7. V-groove Painting
In global market some customers prefer to the edges of SPC flooring to be V-groove and painted with paint, similar to the edges of laminate flooring. They think this kind of flooring looks nicer. Of course, this is an optional working process.
8. IXPE/ EVA underlay laminating
Use hot melt adhesive to stick IXPE /EVA underlay on the back of the SPC flooring, which can make the flooring have better sound insulation effect and better walk feeling. Such products are more high-end.
9. Packing
Choose packing machine with different degrees of automation according to your needs, and there are fully automatic and semi-automatic machines can be optional.
