Application knowledge of coffee shell used in plastic wood composite materials

Application knowledge of coffee shell used in plastic wood composite materials

The coffee industry plays a major role in the global economy, and its impact on the environment is also vital. Every year, more than 2 billion tons of coffee by-products are produced worldwide; traditional wisdom believes that these by-products: coffee grounds and coffee peels will not exist there are too many practical values and applications, and the leftover material of coffee can be processed and reused. Here we will focus on the application knowledge of coffee shells in plastic wood composites.

Because of its own characteristics, coffee shells have application prospects in coffee shell wood-based panels and coffee shell plastic wood composite materials.

Coffee shell artificial board
As a kind of agricultural product processing residue, coffee shell has attracted some researchers' attention. Scientists and technicians have conducted related research on the technology and performance of particleboard produced by coffee shells. The results show that the content of cellulose and hemicellulose in coffee shells is relatively high, and the fiber morphology is also good, which meets the material requirements for the production of wood particles; The research uses isocyanate and urea-formaldehyde resin adhesives, coffee shell and wood shavings at a mass ratio of 1:1 mixed and pressed single-layer structure particleboard performance is better, meet the requirements of relevant standards. According to the existing research, coffee shell not only has considerable content of cellulose and hemicellulose, but also has special substances such as caffeine. Sandalwood flavor and jasmine flavor are added to the adhesive to prepare aromatic fiberboard. The results show that aromatic fiberboard is widely praised for its special aromatic properties. The coffee shell has a natural coffee aroma. It can be considered to prepare composite materials with special sensory functions such as natural aromatic man-made panels, which can not only make the best use of the material, but also improve the product level and increase the added value of the product. The coffee shell contains some minerals and organic nutrients, so it is necessary to pay attention to the influence of these substances when exploring the production process.

Coffee shell plastic wood composite
Plastic wood composite material is a composite material prepared by processing methods such as hot pressing or melt extrusion together with thermoplastic plastics and various additives after pulverized wooden materials such as wood and crop straws. Because of the advantages of both wood and plastic, it is very popular in the market. A key point in the production of plastic wood composites is the compatibility between wood materials and plastics. Because the two have different polarities, it is usually necessary to add a compatibilizer. There is a certain composition difference between coffee shell and general wood materials. Secondly, the proteins and sugars contained in coffee shells will encounter high temperature environments during the production process, and such substances will undergo decomposition and other changes. Dealing with these two points plays a decisive role in preparing qualified coffee shell plastic wood composite materials.
