What is SPC floor?

Jan. 02, 2020

SPC floor is mainly composed of calcium powder and polyvinyl chloride stabilizer in a certain proportion to form a composite flooring material. It is a new material invented in response to national emission reductions. Hard SPC indoor flooring is very popular in foreign home improvement markets. It is a perfect presentation for home decoration. SPC flooring uses calcium powder as the main raw material and is plasticized and extruded Sheet, four-roller calendering hot color film decoration layer and wear-resistant layer, does not contain heavy metals formaldehyde with harmful substances, is 100% formaldehyde-free environmental protection floor, is a true 0 formaldehyde floor.

The thickness is only 4-5.5 mm. The ultra-thin design is a bold innovation in the professional industry. The surface is printed with a material and the substrate is integrated with a 100% high-purity wear-resistant transparent layer. In view of the characteristics of the raw materials, the thermal conductivity is fast and the heat storage duration is long, so it is the first choice for floor heating. Non-toxic and odorless, not afraid of water, fire, or moisture; Anti-slip SPC flooringis superior to laminate flooring in terms of scratch resistance, resource use, and anti-slip performance. There will be no holes on the surface of the SPC floor and no water seepage; there will be no seams after splicing. After staining, you can clean it easily with a rag and wipe it without leaving marks that are difficult to remove, and without special maintenance product keeper.

SPC floor is considered as a new generation of flooring material, which is characterized by: extremely stable, high performance, completely waterproof, high-density sales core, and indentation resistance; it can be easily installed on different types of ground bases, concrete, ceramic or Existing flooring; this is formaldehyde-free, completely safe floor covering material for residential and public environments.

Brief analysis of common problems in SPC floor production-poor product molding

1. The size of the product is unstable, the mold is not full, and the wall thickness is uneven.

Reasons: The formula is unreasonable for internal and external lubrication, the feeding speed is unstable, the screw barrel is seriously worn, and the coordination clearance is incorrect

Solution: Improve the ratio of internal and external lubricants, correct feeding failure, replace the barrel and screw, and adjust the clearance between the barrel and the screw.

2. The product appearance is uneven, the color difference is obvious, and irregular fish scales appear on the surface; the product performance is poor; the toughness is poor, the product is brittle, and the impact resistance is unqualified;

Reasons: The formula structure is unreasonable, the inorganic filling is too high, the plasticization is poor, and the amount of impact materials is insufficient;

Solution: Correct the formula structure, appropriately reduce the content of inorganic fillers, modify the plasticization of the material to about 65%, and add impact materials as appropriate.

3. The output of the finished product wood effect SPC flooring is bent, deformed, and locally subsided;

Reason: the head and the die are not on the same plane, the extrusion speed is too fast, the temperature of cold water is too high, the water pressure is too small, the water flow is insufficient, the water and gas path is not smooth, and the vacuum negative pressure is insufficient;

Solution: Correct the die head and the setting die at the same level, reduce the extrusion speed & cooling water temperature, increase the water pressure and flow, and adjust the vacuum negative pressure to check the water and air channels.
