Testing Methods For Wood Plastic Decking

Wood plastic decking is a new type of deck decoration material. It is made of natural wood as the main raw material and other materials (such as plastic). Compared with traditional wooden decks, wood-plastic decks have higher wear resistance, waterproofness and antibacterial properties, and also have good environmental performance and recyclability. The following introduces the detection methods of wood plastic decking.

Density test: Place the deck on a horizontal surface and use a caliper or measuring instrument to measure the thickness and density of the deck. The higher the density, the better the quality.

Water absorption test: Place the floor on a horizontal platform, drip water droplets on the deck surface, and observe the diffusion of water droplets. The lower the water absorption rate, the better the quality.

Low temperature drop weight impact test: Place the deck in a low temperature environment for a period of time, and then drop it from above the drop weight to observe whether there are cracks or deformations on the deck. The smaller the low temperature impact, the better the quality.

Water absorption size change rate test: Place the deck on a horizontal surface, drip water on the deck surface, and then wait for a period of time to observe the change in water absorption size of the deck. The smaller the water absorption size change rate, the better the quality.

Formaldehyde release test: Place the deck in a sealed space, then introduce formaldehyde gas, and observe whether the deck has a pungent smell. The lower the formaldehyde release, the better the quality.

Surface pollutant corrosion resistance test: Place the deck in a severely polluted environment and observe whether the deck is easily corroded by pollutants. The better the surface's resistance to pollutant corrosion, the better the quality.

Specification and size inspection: Check whether the size of the deck meets the standards and whether the error is within the specified range.

The above is the testing method for wood plastic decking. During the testing process, you need to pay attention to selecting appropriate testing equipment and methods, and comply with relevant experimental operating specifications.
