摘要： The present invention relates to an electrospinning apparatus, and the purpose of the present invention is to provide an electrospinning apparatus capable of producing nanofiber having various ingredients and thicknesses by controlling the temperature of at least one solution discharged from nozzles mounted on the tubular bodies of a nozzle block and thus controlling the viscosity of the solution which is electrospun; producing nanofiber having uniform quality without applying a density difference and a voltage difference by disposing the front end portions of the nozzles in a flare shape; and mass-producing nanofiber at a low cost as well as reducing the amount of the solution used by removing an overflow prevention system and using a metering pump alone or by using the metering pump and the overflow prevention system alternatively or in a hybrid manner.

step 2, delivering the spinning solution in step 1 to the feed port of a degassing vessel from the dissolution vessel after filtration;
step 3, in the degassing vessel, under the conditions of vacuumizing and maintaining the inner pressure of the degassing vessel to be 500-3,000 Pa, performing continuous treatment by a combined degassing process integrating separation, film-scraping, lifting and shear; and
step 4, sampling at a sampling port for the detection of degassing degree, finishing the degassing operation if the detection result is eligible, otherwise repeating step (3) until the detection result is eligible.
The degassing method provided by the present invention has high degassing efficiency and good degassing effect, and is applicable to spinning solutions of a wide range of viscocity.
