China Conical Twin Screw Extruder Capacity 1200-1500kgsh PVC Spc Vinyl Plank Flooring Production Extrusion Line

SPC vinyl floor making machine also named stone plastic composite floor making machine which is used plastic extrusion technology to plasticize PVC with caco3 and other additives into SPC flooring sheet.
1.Product introduction
Rigid multilayer composite PVC plastic floor,Hereinafter referred to as SPC floor. Is based on the new technology to develop new environmental protection floor, Has zero - formaldehyde, mouldproof, moistureproof, fire prevention, insect-resistant, the characteristics of simple installation. Popular in Europe and the developed countries and the asia-pacific market. With its excellent stability and durability, The SPC in stone floor already solved the problem of the deformation of real wood floor be affected with damp be affected with damp mildew, and also Solve the problem of formaldehyde of MDF floor.
2.Technical specifications
SPC floor equipment / PVC stone flooring production line is to PVC and calcium powder as the main raw material production SPC stone floor of the equipment. The raw material is extruded through plasticized extruded sheet, six rolls of hot film and decorative layer. It is 100% free formaldehyde-free floor. At the same time, stone flooring surface embossed wood grain and a variety of patterns, the direct heat of the underlying cushion silencer layer, and then after UV wear-resistant processing, cutting and other processes from the slotted. It is the biggest difference with the traditional floor is environmentally friendly, wear-resistant, fire. Conforms to EN 14372, EN 649-2011, IEC 62321, GB 4085-83;
1.Excellent resistance to bacteria, stain resistance, maintenance-free
2.Flexible, non-slip performance, product water resistance, so easy to clean
3.Wear, antibacterial, not moth, mildew, the surface of the UV treatment has a strong resistance to pollution
4.Good dimensional stability, will not be affected by temperature, moisture deformation, routine maintenance only need to drag and drop
5.Safe, environmentally without formaldehyde
6.Noise reduction, foot comfort, safe non-toxic
7.Color, pattern rich, fully meet the needs of individual design
8.Fire performance B1 level
9.Small joints and seamless welding: special color of the block by the strict construction and installation, the seams are very small.So that the overall effect of the ground and visual effects to maximize the play. Scope: shopping malls, hotels, schools, office purification workshop, factories, hospitals and other places.
3.The main advantages of SPC floor comparison with WPC floor
1.SPC flooring physical indicators more stable and reliable, chemical indicators in line with international standards
2.SPC calcium plastic floor density: 1.9 ~ 2.2 T / cube;
3.SPC calcium plastic floor shrinkage: ≤ 0.8 ‰ (tempering treatment); WPC floor shrinkage: ≤ 2.5 ‰(Shrinkage test standard: 80 ºC, 6 hours of the standard)
4.The thickness of the floor substrate can be controlled within 0.05mm, less than WPC thickness deviation of 0.2mm
5.The corner strength of the latches after the floor is much higher than that of the SPC substrate
6.Long-term use of very small changes in size, hot and cold temperature and sunshine changes are not sensitive
7.online glue-free direct extrusion of multi-layer composite molding, than the WPC floor can reduce the hot press and paste process, greatly reducing the labor and production time
8.SPC floor composed of the base film, color film, substrate and wear-resistant layer between the glue-free bonding strength is much higher than the WPC floor hot press bonding process
9.SPC plate from the extrusion line has been through a tempering treatment, can effectively reduce the post-cutting process of stress and deformation phenomenon.

5.Production Description

SPC flooring production process

Mixing raw material→Extrusion→ UV coating and tempering→ Cutting, grooving→Angle paint (optional) →IXPE/EVA laminating(optional) →Packaging
Step.1---Mixing raw material

According to the formula ratio, pour the raw materials into the high speed mixer to mix(hot mixing temperature: 125 ºC, the function is that mix all raw material uniform, remove moisture in the material; then the raw material goes into the cold mixer (cooling the material, prevent caking and color changing, cold mixing temperature: 55 ºC.),

Step.2---Extrusion

Heat and extrude the raw materials by the twin screw main extruder, form the base board by the T-Die, lamination by the 4 roll (or 6 roll)calender system, base board thickness pressing→PVC film lamination →PVC wear layer lamination →cooling →cutting

Step.3---UV coating and tempering

Surface UV coating → tempering (tempering hot water temperature: 80 ~ 120ºC; cold water temperature: 10ºC.)

Step.4---Cutting, grooving

Cutting, grooving
Step.5---Angle paint (optional)
Step.6---IXPE/EVA laminating(optional)
Step .7---Packaging
