Why is plastic wood more moisture-proof, mildew proof and anticorrosive than anticorrosive wood?

Anticorrosive wood is made of ordinary wood soaked in chemical preservative solution or penetrated by high pressure, so as to make it anticorrosive, moisture-proof, fungicidal, insect-proof, mildewy and waterproof.

Domestic common anticorrosive timber has Russian camphor pine, Nordic red pine or domestic common pine, fir.

In addition, there is a kind of carbonized preservative wood, which is to carbonize the effective nutrients of wood at high temperature, and to achieve the purpose of preservative by blocking the nutritional chain of decaying bacteria.

Plastic wood, also known as wood plastic, refers to the use of polypropylene, polyethylene, polyvinyl chloride and other plastics, instead of the usual adhesive, and more than 35%-70% of the natural plant fiber powder mixed extrusion and composite materials.

So, why is plastic wood more resistant to corrosion, mildew and moisture than anticorrosive wood?

Firstly, the density of plastic wood material is 1.2-1.3g/cm, while the density of conventional anticorrosive wood is only 0.4-0.5g/cm.

The loose fiber structure of anticorrosive wood makes it very easy to absorb the water in the natural environment. The water content of a long time makes it breed mildew in a very short time and produce bloating, cracking, mildew and blackening phenomenon.

But plastic wood material structure is compact, the density is the conventional preservative wood about three times, almost completely does not absorb the moisture in the natural environment, lost the moisture nourishment, also did not have the mold living environment.

Second, the wood plastic material is extruded from thermoplastic and natural wood fiber by high temperature fusion. The material contains no moisture or nutrients. The natural bacteria are also destroyed in the process of high temperature processing, which is completely unsuitable for the breeding of bacteria.

Plastic wood material between the molecular structure is dense, hard surface, also not suitable for insect ant eating.

And anticorrosive wood is on the contrary, the loose structure of anticorrosive wood and easy to absorb water make it become the breeding base of bacteria with high nutrition, the soft fiber also makes it more vulnerable to insects, ants and mice bite, the name of anticorrosive wood is not anticorrosive it is not strange.
