There is the casting knife of the ionic membrane steel band casting machine opened and closed
Technical field
The present invention relates to a kind of manufacturing devices of ionic membrane, and in particular to a kind of ionic membrane steel band stream for having the function of to open and close
Prolong the casting knife of machine.
Background technology
Water electrolysis hydrogen producing, fuel cell, chloric alkali electrolysis etc. industry in largely use rise ion exchange every
Film is perfluorinated ion-exchange membrane, and the batch continuous producing method of the product mainly uses the tape casting.The tape casting is to be dissolved in raw material
Organic solvent is tuned into viscous solution, be cast it is flat and on uniform smooth rotary body, film, this side are formed by baking
The film that method processes has the advantages of uniformity is good, and surface is smooth, functional.But existing at present be cast is used to set
It is standby, after entering the cavity of casting knife due to the slurry of production perfluorinated ion-exchange membrane, it is impossible to which standing and defoaming causes slurry trickling
The bubble generated in the process, flows directly on steel band, the surface of film is made to be mingled with bubble or production defect, it is difficult to process qualification
Film, and after curtain coating, leftover slurry interruption in casting knife cavity is irregularly dropped on steel band, causes to clear up
Steel band is difficult, spends manpower and time.Therefore, it is necessary to design a kind of slurry can in the cavity of casting knife standing and defoaming, even
Continuousization, the casting knife for meeting properties of product requirement, the perfluorinated ion-exchange membrane steel band casting machine that stream is expected being cut off.
