What are the main indicators of treated plywood

2023-05-15

The main indicators of treated plywood can vary depending on the specific treatment process used and the intended use of the plywood. However, some common indicators of treated plywood include:

Preservative retention level: This indicates the amount of preservative that has been added to the plywood during the treatment process. The preservative retention level is usually expressed in pounds of preservative per cubic foot of wood.

Decay resistance: This measures the ability of the treated plywood to resist decay caused by fungi and other microorganisms. Decay resistance is typically measured using a laboratory test method, such as the American Wood Protection Association (AWPA) E10 standard.

Termite resistance: This measures the ability of the treated plywood to resist damage caused by termites and other wood-boring insects. Termite resistance is typically measured using a laboratory test method, such as the AWPA E1 standard.

Corrosion resistance: This measures the ability of the treated plywood to resist corrosion caused by exposure to moisture and other environmental factors. Corrosion resistance is typically measured using a laboratory test method, such as the AWPA E12 standard.

Environmental impact: This refers to the potential impact of the treatment chemicals on the environment. The environmental impact of treated plywood can vary depending on the specific treatment process used and the local regulations governing the use and disposal of treated wood products.

These indicators are important considerations when selecting treated plywood for a specific application, as they can help ensure that the plywood will perform as expected and meet the required standards for durability, safety, and environmental impact.

The range for the main indicators of treated plywood can vary depending on the specific treatment process used and the intended use of the plywood. Here are some examples of typical ranges for each indicator:

Preservative retention level: This can range from 0.25 to 0.60 pounds of preservative per cubic foot of wood for above-ground applications, and from 0.40 to 2.50 pounds per cubic foot of wood for ground-contact applications.

Decay resistance: This is typically measured on a scale of 0 to 10, with a rating of 10 indicating the highest level of resistance to decay.

Termite resistance: This is typically measured on a scale of 0 to 10, with a rating of 10 indicating the highest level of resistance to termites.

Corrosion resistance: This is typically measured on a scale of 0 to 5, with a rating of 5 indicating the highest level of resistance to corrosion.

Environmental impact: The environmental impact of treated plywood can vary depending on the specific treatment process used and the local regulations governing the use and disposal of treated wood products. However, many treated plywood products are now formulated to be more environmentally friendly, with reduced levels of hazardous chemicals and improved recyclability.

It's important to note that the specific ranges for each indicator can vary depending on the country and region, as well as the local regulations and standards governing the use of treated wood products.
