FRP electrolytic cells are widely used in electro-refining & electro-winning industry, such as Pb, Zn, Cu, Mn, and so on. Based on its good anti-corrosion and permeability resistance ability, good integrality, strong shocks resistance ability, light weight, good inner surface hardness, good smoothness, and easy to clean, it’s applied widely.

Material:

Unionsum pays critical attention on cell construction material selection to increase cell service life and decrease maintenance cost.

• Vinyl resin from Shang Wei Fine Chemical Co., Ltd.
• Surface mat and fiberglass from Changzhou Tianma Group Co., Ltd.
• Wood/ Un-conductive magnetic steel reinforce rib inside

Production process:

Due to electrolytic cell with high anti-corrosion requirement, Unionsum will select suitable cell manufacture process according to different cell operation condition (electrolyte and temperature).

• Optimum material composition and mould manufacture process to avoid resin gummosis phenomenon;
• Double-side of plate manufacture synchronously, then coating with yellow gel for oxygen insulation, to increase anti-corrosion and weather resistance performance and service life.
• Reinforced rib with FRP coating manufacture through female mould process, with good integration performance, no layer separation and cavitations between FRP and reinforcing rib, increased cell anti-deformation ability.

Structure:

Unionsum can supply the following cell types based on client requirement (loading capacity, cell inner volume, cell outer edge support span and full deformation):

• Wood as reinforcing rib and cell bottom large rib
• Mixed structure: Un-conductive magnetic steel as cell reinforcing rib and hoop inner rib, wood or both as longitudinal reinforcing rib, wood as bottom reinforcing rib if support span ≤2000mm,steel as bottom reinforcing rib if support span ≥2000mm,
• Un-conductive magnetic steel as reinforcing rib and cell bottom large rib

Advantages:

• Vinyl resin coating on the cell body surface(gel ≥70%).
• Surface mat and chopped strand mat of fiber glass constitute FRP cell body.
• Good integrality, no stitching points, horizontal and longitudinal reinforce rib with FRP coated.
• Good strength, strong impact resistance, large loading capacity.
• FRP density is 1.8kg/cm, lighter than polymer concrete cell.
• Smooth and dense inner surface, easy cleaning, no pollution to anode slime.
• Good insulation of FRP material, no transition of spurious current, no electricity leakage, high electricity efficiency.
• Modular construction, easy transportation and saving carriage, easy installation on site.
• Above 15 year service life, easy maintenance.
