Technological features of welding of plastics based on polyhydroxybutyrate
Main Article Content
Abstract
In particular polymers and biopolymers are increasingly used in various sectors of the economy and more recently biopolymers have been replacing traditional polymers in many applications. The problem of recycling polymeric materials can also be solved by designing products that will facilitate their further processing. In fact, biodegradation is the consistent breaking of chemical bonds of a polymer molecular chain under the action of microorganisms. Destroying a polymer, bacteria, fungi or algae uses the remnants of its molecules as a source of vital organic compounds as well as energy. Usually biodegradation occurs in an aqueous or humid environment during the process of composting. Bioplastics` wastes, like fallen leaves or other organic wastes, are stacked on soil and gradually converted into environmentally friendly material. The ability of a polymer to biodegrade mainly depends on the chemical composition of its molecule. One of the urgent tasks of research and implementation of biopolymers is the connection, in particular welding. Traditionally, plastic welding is widely used in the chemical, food, and other industries, for film packaging and packaging.
