TECHNICAL FIELD
This utility model relates to the technical field of twin-screw extruders, particularly to a bamboo fiber degradation nano material twin-screw extruder.
Background technology
With the increasing importance of environmental protection and sustainable development concepts, bamboo fiber, as a renewable green resource, is widely used in the manufacturing of various industrial products. In order to improve the performance and adaptability of bamboo fiber, many technologies have begun to focus on the degradation and modification of bamboo fiber, especially in the preparation of bamboo fiber degradable nanomaterials. Twin screw extruders have become one of the key equipment in this field due to their efficient mixing and extrusion capabilities. By optimizing screw design and heating control, efficient modification and stable processing of bamboo fiber materials can be achieved, improving their physical properties and processability.
At present, traditional single screw extruders and twin-screw extruders are widely used in the processing of bamboo fibers. Single screw extruders usually rely on a single spiral structure for material transportation and heating, but due to the special properties of bamboo fiber materials, their modification process is complex and prone to material decomposition. The twin-screw extruder can effectively promote material mixing and plasticization through the synergistic effect of twin-screw, thereby improving processing efficiency. Heating devices typically include components such as external heaters and cylinders, but there are certain challenges in handling temperature control and cleaning difficulties. The feeding system often uses spiral feeders to transport materials, but it is difficult to flexibly respond to the processing needs of different materials.
However, existing technologies often face the following problems in the processing of bamboo fiber and its modification: bamboo fiber materials are prone to decomposition during the processing, especially in the heating and mixing stages, due to inaccurate temperature control, which affects the quality and stability of the product. At the same time, traditional equipment design has not fully considered the convenience of equipment cleaning and disassembly, especially for the handling of high-temperature melts and the addition of bamboo fiber materials, which are inconvenient. These issues have led to a decrease in production efficiency and are not conducive to efficient extrusion and processing of bamboo fibers.
Utility Model Content
In order to compensate for the above shortcomings, the present utility model provides a bamboo fiber degradation nano material twin-screw extruder, which aims to improve the problem of difficult control of the temperature of the bamboo fiber material during heating, resulting in decomposition and inconvenient cleaning.
