Abstract

The invention discloses an industrial sizing device for carbon fibers. The industrial sizing device comprises a sizing system, a slurry supply system, a slurry control system and a movable and fixed base frame system, The device can be conveniently grafted to an industrial production line, and sizing production and test of various novel sizing agents and carbon fibers with various sizing rates are realized. By using the industrial sizing device for sizing carbon fibers, the spreading and expanding efficiency of carbon fiber tows is high, the impregnating speed of the sizing agent is high, sizing is uniform, the net-shaped dividing performance of monofilaments is good, and no electric energy is consumed and no waste sizing agent is discharged in a whole sizing production process.

Description

technical field [0001] The invention relates to carbon fiber production equipment, in particular to a carbon fiber industrial sizing device. [0002] technical background [0003] Carbon fiber cannot be used alone, its high performance and multi-function can only be reflected by combining with other materials. Carbon fibers without sizing agent protection cannot be unwound in subsequent composite material processing applications after being wound into ingots, and thus lose their use value. The influence of the use of sizing agent on the physical and chemical properties of carbon fiber composite materials is as follows: (1) the scattered carbon fibers are assembled into a bundle, which is beneficial to weaving, transportation and unwinding; (2) a layer of protective film is formed on the surface of carbon fibers , increase the toughness and friction resistance of brittle carbon fibers, reduce carbon fiber breakage or cracking; (3) introduce active groups on the surface of car...
