A special test sizing device for carbon fiber industrial production line

Abstract

The invention provides a carbon fiber industrialization production line special test sizing device comprising a production line sizing groove. The sizing device is in a welding part structure and comprises a rubber groove frame fixed to the production line sizing groove; the rubber groove frame is fixed to a post through bolts tightly and is fixedly provided with a rubber soaking groove, the post is fixed to the ground through bolts and a clamping sleeve, two ends of the rubber soaking groove are provided with a first rubber soaking roller and a second rubber soaking roller respectively, left and right ends of the rubber soaking groove are provided with a left groove-type roller and a right groove-type roller with wire guide grooves respectively, a control valve for replacing of sizing agent conveniently is arranged at the bottom of the rubber soaking groove, and the length of the rubber soaking groove is consistent with that of the production line sizing groove. By the aid of the carbon fiber industrialization production line special test sizing device, small batches of novel sizing agent can be applied to large-scale carbon fiber production lines for sizing, and the device is low in manufacture and usage cost and safe, simple and rapid to operate.

Description

Technical field [0001] The present invention relates to the technical field of carbon fiber sizing process operation, in particular to a special test sizing device for a carbon fiber production line. Background technique [0002] Carbon fiber is an inorganic polymer fiber with a carbon content of more than 90%, and is usually used as a reinforcing material in advanced composite materials. At the same time, carbon fiber is a brittle material, which is easy to wear and break in deep processing engineering, which affects its full performance. The carbon fiber sizing agent is attached to the surface of the carbon fiber, and the thickness is only tens of nanometers, or even more than a dozen nanometers, but it can protect the carbon fiber from the external environment. At the same time, it has special properties such as bundling, lubricity, wettability and adhesion, so as to ensure To give full play to the performance of carbon fiber. [0003] In the carbon fiber production line, the ...

Problems solved by technology

If it is necessary to try a new type of sizing agent on the production line, it will bring two problems: first, the entire carbon fiber production line needs to be stopped first, the sizing tank must be thoroughly cleaned and then replaced with a new type of sizing agent, and then restarted for trial use; Second, it is necessary to provide large quantities of new sizing agents to meet the needs of the entire large-scale production line

In fact, there are relatively large defects in using this device to test small batches of new sizing agents, which are mainly manifested in: (1) There are large objective differences between small-scale test lines and large-scale production lines, such as oxidation process, carbonization process, surface treatment methods, The key influencing factors such as production line speed, sizing agent content and drying temperature cannot be exactly the same, and there is a big difference with the large-scale production line; The development progress of the new sizing agent is hindered, and it is not conducive to the control of the total cost of research and development
