Production Process of SPC Floor

The main raw materials for SPC flooring production are calcium carbonate, polyvinyl chloride (PVC), and various additives. Calcium carbonate, accounting for about 60 - 70% of the total raw materials, provides hardness and stability. PVC serves as the binder, giving the flooring flexibility and strength. Additives such as stabilizers, lubricants, and colorants are also crucial. Stabilizers prevent the degradation of PVC during high - temperature processing, lubricants help with the smooth flow of materials, and colorants are used to create a wide range of colors and patterns. These raw materials are carefully measured and mixed in precise proportions according to the product formula.

The mixed raw materials are fed into an extruder. Inside the extruder, under high temperature and pressure, the materials are melted and homogenized. The extruder then forces the molten mixture through a die with a specific cross - section, which determines the basic shape of the loose lay vinyl flooring. The extrusion process needs to be precisely controlled in terms of temperature, pressure, and extrusion speed to ensure the uniform thickness and density of the flooring.

After extrusion, the hot SPC flooring planks enter a cooling system. This can be a water - cooled or air - cooled system, or a combination of both. The rapid cooling process helps the planks solidify quickly and maintain their shape. During this stage, the planks are also shaped further. For example, edges may be trimmed to ensure a perfect fit during installation, and surface textures may be embossed onto the planks using rollers with specific patterns.

To enhance the aesthetic appeal and functionality of SPC flooring, a decorative layer and a wear - resistant layer are often laminated onto the base layer. The decorative layer, usually a printed film with various designs such as wood grain, stone pattern, or tile look, is adhered to the base layer using adhesives or heat - pressing techniques. On top of the decorative layer, a transparent wear - resistant layer, typically made of a special polyurethane material, is applied. This layer protects the decorative layer from scratches, stains, and fading, increasing the lifespan of the flooring.

Once the lamination is complete, the SPC flooring planks undergo edge treatment. This may include beveling the edges to create a more natural look when installed, or adding a micro - bevel for a seamless appearance. After edge treatment, the planks are cut to the required lengths and widths according to market demand and product specifications.

Finally, each SPC flooring plank goes through a strict quality inspection. Inspectors check for defects such as uneven thickness, surface scratches, color variations, and improper edge treatment. Planks that meet the quality standards are then packaged, usually in cartons, with protective materials to prevent damage during transportation and storage.

III. Precautions

A. Installation Precautions

1. Subfloor Preparation: Before installing SPC flooring, the subfloor must be clean, dry, flat, and free of debris. Any unevenness in the subfloor can cause the SPC planks to buckle or creak. For concrete subfloors, proper moisture testing should be carried out to ensure that the moisture content is within the acceptable range.
2. Acclimation: SPC flooring should be acclimated to the installation environment for at least 48 hours before installation. This allows the planks to adjust to the temperature and humidity of the room, reducing the risk of expansion or contraction after installation.
3. Installation Tools: Use appropriate installation tools such as a tapping block and pull bar for click - lock flooring to ensure a proper fit. For glue - down flooring, use the correct type of adhesive and spread it evenly to avoid uneven bonding.

B. Maintenance Precautions

1. Regular Cleaning: Sweep or vacuum the SPC flooring regularly to remove dirt and debris. Use a damp mop with a mild cleaning solution for deeper cleaning, but avoid using excessive water, as standing water can seep into the joints over time.
2. Avoid Harsh Chemicals: Do not use abrasive cleaners, solvents, or strong chemicals on SPC flooring, as they can damage the wear - resistant layer and the decorative layer.
3. Furniture Protection: Place felt pads or coasters under the legs of furniture to prevent scratches and indentations. When moving heavy furniture, lift it rather than dragging it across the floor.
