What Are The Main Characteristics Of Wood-plastic Composites? What Are The Advantages And Disadvantages Of Wood-plastic Materials

The main characteristics of wood-plastic composites are as follows:

A. It has good social economy and sustainable development, and is especially suitable for the national policy of "forest protection" in China.

B. Durable, long life, similar to wood appearance, higher hardness than plastic;

C. It has excellent physical properties, better dimensional stability than wood, no cracks, warping, no wood knots, twills, adding colorants, covering film or composite surface can be made into various products with brilliant colors;

D. It has the processability of thermoplastic plastics and is easy to form. It can be processed with general plastic processing equipment or a little modification. The new investment of processing equipment is less, which is convenient for popularization and application.

E. It has secondary processability similar to wood and can be cut, bonded and fixed with nails or bolts.

F. It is conducive to decoration and decoration. It can be painted and beautified. The product specifications and shapes can be adjusted according to user's requirements. It has great flexibility.

G, not afraid of moths, aging resistance, corrosion resistance, low water absorption, no moisture deformation; h, can be reused and recycled, can be biodegradable, protect the environment;

I. It is beneficial to environmental protection and can be made of waste wood chips, crop fibers and waste plastics.

J. Rich resources, low cost and low use cost. At present, the disadvantages and shortcomings of wood-plastic composites are that the toughness is lower than that of parent plastics, and the processing equipment and downstream devices need to be adjusted and reformed accordingly. We believe that with the joint efforts of scientists and technicians from all over the world, the shortcomings will be improved in the near future.
