Thermal insulation and temperature control device for special test dipping tank for carbon fiber production line

Abstract

The invention provides a heat preservation and temperature control device for a test impregnation tank special for a carbon fiber production line. The device comprises a heat preservation mechanism and a temperature control mechanism. The heat preservation mechanism comprises a left heat preservation cover and a right heat preservation cover. The left heat preservation cover and the right heat preservation cover are turnable heat preservation covers and arranged on the edges of the two sides of the impregnation tank respectively, and the left heat preservation cover and the right heat preservation cover are each provided with a through opening for carbon fibers to penetrate through. The temperature control mechanism comprises a stainless steel heat preservation shell, a temperature measuring probe and a thermostatic water bath circulating device. The device is simple and practical in structure and can be matched with different sizing devices, and the structures of the original sizing devices do not need to be changed. Through the improvement of the heat preservation and temperature control device, energy consumption in the testing and production processes can be reduced, meanwhile, the sizing effect is improved, and the quality of the surfaces of the carbon fibers is improved.

Description

Technical field [0001] The invention relates to a heat preservation and temperature control device for a special test dip tank for a carbon fiber production line. Background technique [0002] The sizing process is an important part of the carbon fiber production process, which includes yarn guiding, dipping and controlling. Through the above process, the effective control of the uniformity of the sizing agent on the surface of the carbon fiber can be achieved. The following requirements are put forward for the equipment required for the process: easy operation, low loss, controllability and safety. [0003] The sizing agent is a water-soluble emulsion with water as the main solvent, and its main component is generally composed of resin, emulsifier, auxiliary and deionized water. The main principle is to “connect” the resin, additives and water under certain conditions through the emulsifier of the amphiphilic molecule to form an aqueous emulsion with a milky white appearance.
