Problems solved by technology

If the carbon fiber sizing amount is uneven, the width of the carbon fiber tow and the appearance shape are irregular, the manufacturability is relatively poor when the carbon fiber is made into a prepreg or woven into a fabric, and the shape of the prepreg and braid is difficult to be accurate control, which in turn affects the properties of the final material
[0003] At present, the commonly used carbon fiber washing and drying and sizing drying equipment in China is relatively backward. Most of them are horizontal furnaces and vertical furnaces. Disadvantages of large land and high cost
The most important thing is that the width of the carbon filament cannot be widened well, resulting in different widths of the wire width, which is not conducive to the later weaving and application

Embodiment 1

[0033] The temperature of the washing and drying hot roller is raised in advance, and the temperature setting value is 147°C. After rising to the target temperature, the washed 12K T700 carbon fiber is inserted into the washing and drying hot roller unit at a line speed of 8m / min.

[0034] Prepare a slurry with a concentration of 4.5%, mix it evenly, put it into the sizing tank through a circulating pump, and turn on the temperature control system. When the temperature of the slurry in the tank is 25±2°C, connect the carbon fiber from the washing and drying hot roller unit, and then The sizing process is completed through each transmission smooth roller. When the carbon fiber passes through the second extrusion roller, the hand valve is used to close the extrusion rubber roller group, and the stroke scales on both sides of the first extrusion roller are kept consistent for extrusion. Both are 20.35mm.

[0035] The temperature of the hot roller group of the drying and setting s...

Embodiment 2

[0037] Adopt the same water washing drying and sizing drying temperature as in Example 1, but the difference from Example 1 is that the stroke of the squeezing roller is 20.20mm.

Embodiment 3

[0039] The temperature of the water-washing and drying hot roller is raised in advance, and after the temperature is raised to 160°C, the water-washed carbon fiber is inserted into the water-washing and drying hot roller unit at a line speed of 8m / min.

[0040] Prepare a slurry with a concentration of 4.5%, mix it evenly, put it into the sizing tank through a circulating pump, and turn on the temperature control system. When the temperature in the tank is controlled at 25±2°C, the carbon fiber of the washing and drying hot roller unit passes through each transmission light in turn. The roller completes the sizing process. When the carbon fiber passes through the second extrusion roller, use the hand valve to close the extrusion rubber roller group, and keep the stroke scales on both sides of the first extrusion roller consistent for extrusion. The strokes on both sides are 20.25mm .

[0041] Heat up the hot roller of the drying and setting system in advance, and insert the car...

Abstract

The invention discloses a system for water-washing drying, sizing and drying setting of carbon fiber. The system comprises a water-washing drying hot roller unit, a sizing system, an extruding rubber roller set and a sizing drying hot roller setting unit, the water-washing drying hot roller unit is used for drying moisture of the carbon fiber in a water-washing section and comprises a first hot roller unit and a first heating system, the sizing system is connected to the water-washing drying hot roller unit, the extruding rubber roller set is connected to the sizing system and used for extruding spare sizing agent in tows of the carbon fiber and comprises a first extruding roller and a second extruding roller in parallel arrangement, and the sizing drying hot roller setting unit is connected to the extruding rubber roller set and used for drying moisture in the sizing process and expanding silk width of the carbon fiber and comprises a second hot roller unit and a second heating system. The system saves space and can remarkably reduce broken filament amount of the carbon fiber and increase the silk width.

Description

technical field [0001] The invention belongs to the technical field of carbon fiber production, and relates to a system for washing and drying, sizing and drying and shaping of carbon fibers. Background technique [0002] Carbon fiber is a new type of material, which has the advantages of low density, high strength, high temperature resistance, corrosion resistance, etc. It has been widely used in aerospace, ships, automobiles and other fields. And other fields of application are becoming more and more extensive, belonging to military and civilian dual-use high-tech new materials. The preparation process of carbon fiber carbonization process includes pre-oxidation, carbonization, surface treatment, washing, washing and drying, sizing and drying. Sizing and drying are the last process in the carbon fiber preparation process. The purpose of sizing is to increase the carbon fiber's clustering, wear resistance and water absorption resistance. Through sizing treatment, the mecha...
