Description

Plastic-wood section bar with central cylindrical hole

Technical Field

The utility model discloses what take plastic-wood section bar in center cylinder hole related to is a combined material section bar, belongs to combined material and novel chemical building materials technical field.

Background

The section bar is an object with a certain geometrical shape, which is made of iron, steel, plastics or other materials with certain strength and toughness through the processes of rolling, extruding, casting and the like, and has a certain appearance size and a certain fixed cross section shape. The section bar can be used independently and can be further processed into other manufactured products, and the section bar is widely applied to the fields of building structures, manufacturing and installation and the like.

Traditionally, the material used for the profile is generally metal, plastic, wood or glass fiber reinforced plastic. The section bars made of the materials have certain limitations in the production or use process. For example, metal section bars are heavy, easy to rust, expensive, high in energy consumption in the production process and the like; the plastic section bar is easy to age, easy to deform, and environment-friendly; the wooden section is easy to crack, easy to damage by worms and easy to color, and trees need to be felled when the wooden section is produced, so that the wooden section is not beneficial to water and soil conservation, environmental protection and the like; the glass fiber reinforced plastic section is high in pollution in the production process, and cannot be regenerated after being discarded.

The plastic-wood composite material is prepared by taking low-value biomass fibers such as wood powder, crop straw powder, rice bran powder and the like as main raw materials, mixing the main raw materials with plastics, and carrying out processes such as extrusion, mould pressing and the like, and has the advantages of raw material recycling, product plasticity, environmental protection in use, cost economy, recycling and biochemical treatment and the like. With the increasing acceptance of the advantages of wood-plastic products, the range of applications is rapidly expanding, and the types of products involved are wall panels, skirt panels, floors, galleries, great wall panels, handrails, guardrails, racks, shelves, and the like.

Therefore, the plastic-wood section with the central cylindrical hole fully exerts the advantages of the plastic-wood material, has a specific shape, better meets the market requirements, and is very necessary.
