High-performance fiber drying detection testing machine

Abstract

The invention provides a high-performance fiber drying detection testing machine which comprises a stand, a drying mechanism, a winding mechanism and a translation mechanism; the drying mechanism comprises a drying box body, a heating box, a silk supporting roller, a return air pipe, a fan and a pressure-equalizing box; a box door which is provided with a testing port is installed on the front surface of the drying box body; a return air inlet and the pressure-equalizing box are respectively arranged at the top and the bottom of the drying box body; a pressure-equalizing distribution outlet net plate and a static-pressure distribution inlet net plate are arranged above the pressure-equalizing box; the winding mechanism is installed at one side of the silk outlet of the drying box body; and the translation mechanism is used for the horizontal movement of the drying box body. The invention has reasonable structure and convenient operation, can be matched with a synchrotron radiation device, can accurately detect the structural evolution condition of a high-performance fiber silk bundle in the drying process in time, supplies a strong technical support for the drying process design of high-performance fiber production, and overcomes the defects that the debugging period of a trial and error method is long and the fiber quality can not be ensured.

Description

technical field [0001] The invention relates to a high-performance fiber drying testing machine. Background technique [0002] High-performance fibers represented by carbon fiber, aramid fiber and high-strength high-modulus polyethylene fiber play a pivotal role in modern warfare, aerospace, sea defense, weaponry and other fields due to their excellent performance; at the same time, they are used in automobiles, ships , rope nets, medical equipment, sports equipment and other fields also have broad application prospects. [0003] The preparation process of high-performance fibers is long, complex, and has many adjustable parameters, and each step of the process has a great impact on the final performance of the fibers. In the preparation process of high-performance fibers, drying treatment is required. Drying treatment is not only a process of evaporating water and solvents, but also a process of gradually weakening the plasticizing effect in the fiber, which promotes the i...

Problems solved by technology

[0004] However, at present, the process design of high-performance fiber production still adopts the traditional "try-and-try method", that is, the process parameters are determined after repeated debugging before the production line is started. The structure is tracked and detected in real time, so that the quality of the fiber cannot be guaranteed
