Cyclic cooling device for water for carbon fiber surface sizing agent content measuring

Abstract

The invention relates to a cyclic cooling device for water for carbon fiber surface sizing agent content measuring, and belongs to the field of carbon fiber production. A cyclic water tank enters a condensation device connected in a series connection form through a manual valve A and a circulation water pump. A condensation device water outlet returns to the cyclic water tank through a pipeline Awater return port. A pressure sensor is arranged in a pipeline A and connected with a programmable controller, and the programmable controller controls the rotation speed of the circulation water pump. A temperature sensor is arranged in the cyclic water tank and connected with the programmable controller, the programmable controller controls a cooling tower fan and an electromagnetic valve on a cooling tower water outlet pipeline, and a cyclic water tank water outlet B is connected with a cooling tower through a manual valve B, a cooling water pump and a pipeline B. An input type liquidometeris arranged in the cyclic water tank and connected with the programmable controller, the programmable controller controls the on-off states of an electromagnetic valve on a pipeline C, and the wateroutlet end of the pipeline C is connected with the cyclic water tank.

Description

technical field [0001] The invention belongs to the field of carbon fiber manufacture, and specifically relates to an adjustment tool for a bearing bush used in a centerless grinder. Background technique [0002] It is well known that the mechanical properties of carbon fiber composites depend not only on the properties of the fiber and resin itself, but also largely on the interfacial bonding properties of the composite. By introducing a sizing agent between the carbon fiber and the matrix resin, the sizing agent is like a bridge, which not only changes the physical structure and chemical properties of the fiber surface, but also promotes the chemical combination between the fiber and the resin. On the basis of making up for the defects of the original components, It also takes full advantage of the advantages of fibers and resins, which directly affects the macroscopic mechanical properties of composite materials. Therefore, the sizing process is an indispensable link in ...
