Description

Technical Field

[0001] The invention relates to the technical field of production of short-filament carbon fiber composite insulation cylinders, in particular to a continuous production system of short-filament carbon fiber composite insulation cylinders. Background Art

[0002] Short-filament carbon fiber composite insulation cylinder is a composite product composed of short-filament carbon fiber and other materials, mainly used for thermal insulation. They have excellent thermal insulation performance, light weight, high strength and good corrosion resistance. As a reinforcing material, short-filament carbon fiber can improve the strength and stiffness of the composite material, while other components of the composite material (such as resin or foam material) provide good thermal insulation performance. This kind of insulation cylinder is usually used for the insulation of industrial equipment, pipelines, and storage tanks, especially in high or low temperature environments, to ensure the effective transmission of heat energy and energy conservation. In addition, because of its excellent physical properties, short-filament carbon fiber composite insulation cylinder is also widely used in aerospace, automobile, construction and other fields.

[0003] The Chinese patent application number 201810959133.X discloses a method for preparing a low-density, multi-angle woven carbon fiber rigid insulation tube, which specifically includes the following steps: cutting the carbon fiber short, combing it into hair with a carding machine and making it into a mesh; needling it into a mesh unit; wrapping the mesh unit around the support mold and needling it to form needle-punched fibers at angles from -90 degrees to more than 90 degrees; using a high-penetration mist spraying method to spray the above-prepared embryo in one direction; the infiltrated material is successively hot-pressed, carbonized and purified to obtain the primary product of the carbon fiber insulation tube, which is then mechanically processed into the product required for the high-temperature furnace. Compared with the existing product soft felt winding and vapor deposition shaping method, it has good thermal insulation; the service life is doubled; the use of high-penetration spraying can ensure the uniform density and stable performance of the product; the product has a wide application environment.

[0004] However, the production of existing short-filament carbon fiber composite insulation tubes cannot be continuous, and the fiber filaments cannot be fully adsorbed, resulting in poor performance; at the same time, some waste liquid will be generated during the production process of the short-filament carbon fiber composite insulation tube. These waste liquids contain substances such as uncured resin. If not handled properly, they may cause environmental pollution and health risks. Summary of the invention
