Product Mix

1.Substrate Layer

Material composition: The substrate layer is usually made by mixing wood powder and thermoplastic (such as polyvinyl chloride PVC) to form a sturdy base layer.

Functional features: This layer is responsible for providing support and load-bearing capacity, while also having good rigidity and toughness, and is not easily deformed or cracked.

2.Decorative Layers

Diverse textures: The decorative layer replicates various textures through printing technology, such as wood grain, stone grain, carpet grain, etc.

Visual effect: This layer directly determines the appearance of the wall panel, and through high-tech printing technology, extremely realistic decorative effects can be achieved to meet the needs of different consumers.

3.Wear resistant layer

Material thickness: Transparent polymer PVC material is usually used, with a thickness between 0.3mm and 0.7mm.

Functional features: This layer has super strong wear resistance, which can effectively reduce wear and tear in daily use and extend the service life of the wall panel. At the same time, it also has a certain anti-pollution ability.

4.Bottom layer materials

Structure type: The underlying material may include additional sound insulation layers or layers to enhance stability, depending on the design requirements of the product.

Function: The presence of the underlying material makes the wall panel more stable during installation and use, while also providing good insulation against sound and vibration from the underlying layer.

Production Process

1.Raw Material Preparation

Material selection: The main raw materials include recycled plastic pellets and wood fibers, which are screened and pre treated to ensure quality.

Ingredient mixing: Mix plastic particles and wood fibers in a certain proportion, and add necessary stabilizers, lubricants, antioxidants, and other additives.

2.Mixed Granulation

Mixed granulation: The mixture is uniformly mixed using a high-speed heating and cooling mixer, and then granulated using a cone double wood plastic granulation unit to form raw material particles for extrusion.

Equipment requirements: Equipment suitable for this process includes a stainless steel three-stage air delivery system and a granulation equipment with a daily output of 2-4 tons.

3.Extrusion Molding

Extrusion process: Put the produced wood plastic particles into an extruder and extrude them into the desired grid shape through high temperature and pressure. Temperature control: Accurate temperature control is required during the extrusion process to ensure material fluidity and molding quality.

4.Cooling and shaping

Cooling treatment: The extruded grille wall panel needs to undergo cooling and shaping treatment to ensure its dimensional stability and shape accuracy. Equipment support: The product can be quickly cooled using a cooling water tank or a cooling air knife.

5.Post processing

Surface treatment: Surface treatment of the grid wall panel is carried out as needed, such as spraying a waterproof coating or texture processing, to enhance the beauty and durability of the product. Cutting and packaging: Cut the finished product to ensure that the size meets the requirements, conduct quality inspection, and finally package and store it.
