Description

technical field [0001] The invention relates to the technical field of spinning instruments, in particular to an electrostatic spinning instrument with VOCs treatment in the spinning process and adjustable temperature and humidity. Background technique [0002] With the rise of nanotechnology, people have paid great attention to the electrospinning method that can prepare continuous micro-nano fibers. The electrospinning method is prepared by stretching polymer solutions or melts through the electric field force generated by a high-voltage electrostatic generator. An important method of ultrafine fiber is a method of spinning nanofibers with simple operation, wide application range and relatively high production efficiency.

Problems solved by technology

[0003] People have made a systematic study on the spinning process, and found that the mass fraction of polymer solution, spinning voltage, receiving distance, nozzle aperture and ambient temperature and humidity are important factors affecting the diameter and morphological structure of the spinning fiber; among them, the ambient temperature and humidity It is also the key to the quality of fibers, and compared with other factors, the parameters of temperature and humidity are more difficult to control accurately. Among them, the treatment of volatile organic solvents in the spinning process, the treatment of VOCs in the polymer spinning process and the adjustment of temperature and humidity are all important factors. It has always been the difficulty that solution electrospinning needs to overcome

[0004] The electrospinning device in the prior art is not equipped with a mechanism that can adjust the spinning temperature and humidity and VOCs treatment in the spinning process to adjust and control the temperature and humidity in the processing process and the toxic, harmful, and organic reagent waste gas pollutants disposal device. This will inevitably lead to poor quality of spun fibers and environmental pollution, which cannot further promote the development of electrospinning; in view of these defects, it is necessary to design an electrospinning instrument with VOCs treatment in the spinning process and adjustable temperature and humidity of
