Problems solved by technology

[0002] At present, there are more and more carbon fiber technologies, but each has its own shortcomings. For example, the existing carbon fiber manufacturing processes have unreasonable process arrangements, unreasonable selection of process parameters, and unreasonable collocation of process parameters. Higher requirements, thereby increasing production costs

Embodiment 1

[0017] The carbon fiber manufacturing process includes the following steps:

[0018] Stock solution→spinning→collecting→rewinding→collecting→drying furnace→pre-oxidation furnace 1→pre-oxidation furnace 2→pre-oxidation furnace 3→low temperature carbonization furnace→high temperature carbonization furnace→surface treatment 1→surface treatment 2→surface treatment 3→Washing→Drying furnace→Sizing→Drying furnace→Reeling;

[0019] 1), pre-oxidation process

[0020] During the pre-oxidation process, the temperature is between 220°C. When the temperature is about 238°C, the oxygen content in the silk rises rapidly, and a chemical reaction can occur; the temperature remains uniform and stable, and the small molecules and other impurities produced in the reaction are taken away by circulating air And the heat of reaction to ensure continuous pre-oxidation; the reaction time of pre-oxidation process takes 80 minutes; among them, the temperature change in pre-oxidation furnace 1→pre-oxidation fu...

[0028] 1), pre-oxidation process

[0029] During the pre-oxidation process, the temperature is between 280℃. When it is about 238℃, the oxygen content in the silk rises rapidly, and chemical reaction can occur; the temperature remains uniform and stable, and the small molecules and other impurities produced in the reaction are taken away by circulating air And the heat of reaction to ensure continuous pre-oxidation; the pre-oxidation process takes 100 minutes; the temperature change in the pre-oxidation furnace 1→pre-oxidation furnace 2→pre-oxidation furnace 3 is contro...

Embodiment 3

[0035] The carbon fiber manufacturing process includes the following steps:

[0036] Stock solution→spinning→collecting→rewinding→collecting→drying furnace→pre-oxidation furnace 1→pre-oxidation furnace 2→pre-oxidation furnace 3→low temperature carbonization furnace→high temperature carbonization furnace→surface treatment 1→surface treatment 2→surface treatment 3→Washing→Drying furnace→Sizing→Drying furnace→Reeling;

[0037] 1), pre-oxidation process

[0038] During the pre-oxidation process, the temperature is between 260°C. When the temperature is about 238°C, the oxygen content in the silk rises rapidly, and a chemical reaction can occur; the temperature remains uniform and stable, and the small molecules and other impurities generated in the reaction are taken away by circulating air And reaction heat to ensure continuous pre-oxidation; the pre-oxidation process takes 90 minutes; the temperature change in the pre-oxidation furnace 1→pre-oxidation furnace 2→pre-oxidation furnace 3...
