| Abstract [eng] |
Nowadays, synthetic materials such as plastic are an integral part of society's life, due to their extremely wide range of uses. The growing demand for products made from synthetic materials is a major environmental concern due to the long-life cycle of these materials. Biocomposites of hemp seed husks are an excellent alternative to solving this problem. These materials of natural origin can be returned to the environment at the end of their life cycle and thus become raw material for further biological processes. The ever-increasing production of plant-based products increases the amount of cellulosic waste that can be used, in this case hemp seed husks, to create a value-added product that reduces the negative impact on the environment. This work is divided into four main sections: literature review, a chapter on research section, engineering section and worker safety and health. This work discusses the most important aspect – the formation of a biocomposite and the investigations in its properties. The following components are used to produce the biocomposite: hemp seed husks, cellulose diacetate and triacetin. By changing the ratio of these components and the size of the hemp seed husk particles, biocomposites with different component composition were formed and their properties were investigated. Using the AutoCAD programming software, a recommended technological scheme for the production of hemp seed husk biocomposite pellets has been designed. A detailed description of the principal scheme for the production of hemp seed husk biocomposite pellets is provided. Yearly, weekly, daily, single–shift and hourly of components required for the production of hemp seed husk biocomposite pellets have been calculaten. Professional risk factors that may appear in the work environment are also discussed. |
