The hottest wood plastic composite production of a

Wood plastic composite production of a variety of profiles

for the reinforcement of plastics, in addition to traditional glass, aromatic nylon fiber and carbon fiber, natural fiber is being used more and more. In many cases, wood fiber and sawdust filled plastic can be a good substitute for natural wood or MDF. Jiaozuo new energy company will supply 40000 144v120ah power battery packs (with a total price of 1.4 to 1.6 billion yuan) to xindayang company, which can also open up a broader market. Wood fibers are used together with thermoplastics to produce a wide variety of profile products. The proportion of wood can be as high as 90%

any marked line is drawn on the prepared sample by printing or hand (the addition of the mark line will not have any impact on the sample). The desired profile can be produced by extrusion in one production step without any post-processing, which means that the cost advantage can also be realized in production. This paper summarizes this interesting material combination, which has been improved completely in recent years

Xinai additive, now the main component. When processing thermoplastic polymers, wood and other natural fibers have many advantages compared with inorganic fillers and reinforcing fibers. They are lighter and less likely to adhere. Of course, the material is renewable. For example, sawdust can be used as a filler to reduce material costs, but it can also be used to improve strength or dimensional stability independent of temperature. The disadvantage is that the weight has increased

the combination of wood and thermoplastic is not a new thing, but relying on new technology, wood has developed from a simple additive to assume the role of principal component, with new properties and possibilities. Wood extrusion has been used in the United States for decades, but compared with plastic extrusion and whole wood processing, it has not won a large market scale. In the early 1980s, the interior parts of the automobile industry began to be used commercially, and have continued to develop since then. The first International Symposium on wood plastic composites was held in Madison, USA, in 1991. From 1990 to 2000, the U.S. market grew by about 135%, especially in the past five years

European extruded wood fiber filled thermoplastics can be traced back to 1977. At that time, however, the wood content was only 30%. In the course of time, this proportion has increased significantly

"liquid wood" is sometimes incorrectly used to form wood. Liquid wood is used to describe materials that use lignin as a basic component. Lignin is mixed with natural fibers and heated to produce fiber composites that can withstand further processing

new competition faced by wood extrusion the superior government of the two materials will give full support to reduce the use of hydrofluorocarbons, which is very effectively combined. There is a synergy between the positive properties of wood and various economical processing methods used in plastic technology. However, it must be considered that the properties of wood fiber material profiles cannot be compared with those of polypropylene (PP), polyethylene (PE) or polyvinyl chloride (PVC) materials. In other words, in terms of the prominent position of PVC for window frame profiles, wood fiber materials will not change anything. Wood extrusion is more positioned in the markets involved by traditional materials such as wood or medium density fiberboard
