Problems solved by technology
But there are still the following deficiencies: 1. There are phenomena such as uneven extrusion density and non-compactness in the processing process of the FRP diaphragm frame formed by one-time extrusion. Bonding and curing, there are phenomena such as brittleness and easy fracture at the joint part; 2. The FRP diaphragm frame formed by one-time extrusion has corrosion phenomenon, and the glass fiber cloth on the surface explodes and pulverizes, and some diaphragm frames break and collapse. Defects such as short service life (about one year on average) lead to the liquid level difference between the anode and cathode in the electrolytic cell unable to meet the technical requirements, which has a great impact on product quality

Embodiment 1
[0010] Epoxy methacrylate vinyl ester resin is used to fill it uniformly and continuously into the mold cavity, after resin pouring, curing to integral molding and demoulding. The manufactured diaphragm frame has good corrosion resistance and two-way strength, so that the overall molded FRP diaphragm frame has a long service life and good production and operation effects.
Embodiment 2
[0012] MFE-3 vinyl ester resin is used to uniformly and continuously fill it into the mold cavity, and after resin pouring, curing to integral molding and demoulding. The manufactured diaphragm frame has good corrosion resistance and two-way strength, so that the overall molded FRP diaphragm frame has a long service life and good production and operation effects.

The present invention relates to an improvement of a diaphragm holder for diaphragm electrolysis. It is characterized in that the diaphragm frame is made of epoxy methacrylic vinyl ester resin or MFE-3 vinyl ester resin by integral molding. The diaphragm frame used for diaphragm electrolysis of the present invention is formed by a continuous production process and has good corrosion resistance and bidirectional strength, so that the integrally molded FRP diaphragm frame has a long service life, good production and operation effect, and no Due to the collapse and fracture of the diaphragm frame, the liquid level difference between the cathode and anode in the electrolytic cell cannot meet the stable control of process technical conditions and the impact on product quality.
Description
technical field [0001] The invention relates to an improvement of a diaphragm frame for diaphragm electrolysis. Background technique [0002] At present, in the process of nickel electrolysis, the diaphragm frame used is assembled by extruding a single piece of FRP diaphragm frame and corresponding spacers. The application of FRP diaphragm frame effectively solves the problem of iron pollution in electrolytic nickel production. But there are still the following deficiencies: 1. There are phenomena such as uneven extrusion density and non-compactness in the processing process of the FRP diaphragm frame formed by one-time extrusion. Bonding and curing, there are phenomena such as brittleness and easy fracture at the joint part; 2. The FRP diaphragm frame formed by one-time extrusion has corrosion phenomenon, and the glass fiber cloth on the surface explodes and pulverizes, and some diaphragm frames break and collapse. Defects such as short service life (about one year on ave...
