Commonly used FRP anti-corrosion include: , FRP lining: water tanks, pools, pipes, storage tanks, etc.
, Resin clay brick lining
Glass flake lining
, Epoxy self-leveling floor
, epoxy powder spraying, base material surface coating with FRP, etc.
FRP anti-corrosion lining FRP storage tanks, storage tanks, cement pool linings and metal shell FRP linings (or cladding) are made of corrosion-resistant resin and The glass fiber surface felt is used as the anti-corrosion layer, and unsaturated polyester resin and medium-alkali glass fiber cloth are used as the reinforcing layer, which has high corrosion resistance. Good strength and long service life. It is widely used in storage tanks, pickling tanks, ion exchangers and other equipment in electric power, metallurgy, petroleum, chemical industry, printing and dyeing, machinery, environmental protection and other industries. 1. Epoxy, furan, polyester, and phenolic linings Epoxy, furan, polyester, and phenolic linings are all hand-lay-up molded linings. Different raw materials are selected depending on the medium temperature and pressure. Features: strong adhesion, low cost, simple process, good anti-corrosion performance, uniform color, good integrity, aging resistance, wear resistance, impact resistance and pressure bearing. When using epoxy, furan, polyester, or phenolic linings, whether the surface is a metal surface or a cement surface, the primer must be sprayed with epoxy resin first, so that the base bond can be stronger. Physical properties: Compressive strength 3/. Impact strength /, this lining is widely used in anti-corrosion and leak repair projects in chemical pharmaceuticals, power plants, communications, metallurgy, shipbuilding and other industries. 2. Overview of the Concrete Lining R Construction Plan This construction plan makes clear requirements for the material selection, construction, and inspection of the project based on the user's technical conditions. Material selection: Use epoxy resin (produced by Sinopec Corporation). Corrosion resistance: Resistant to hydrochloric acid (3), sodium hydroxide (3), subchlorine (available chlorine), temperature resistance
°C or below. Inspection standards: On-site construction and inspection shall comply with the "Code for Construction Anticorrosion Engineering and Acceptance". Construction technology: erect scaffolding, lay the treads and fix them. Inspect interior surfaces: Remove concrete residue from interior surfaces. Inner wall treatment: Use electric tools to polish the smooth inner wall, remove protrusions, and clean the loose soil on the surface to ensure that the inner surface is clean. As a base coat: apply a layer of resin evenly on the clean concrete surface, and then apply the next step after solidification. Repair layer: Fill the pits on the inner surface with resin putty to prevent voids and bubbles from appearing during R lamination. As the anti-corrosion layer: use a layer of alkali-free chopped strand mat + a layer of glass surface mat, which requires all the fibers to be soaked, and the R bubbles to be discharged, and compacted to make the surface smooth and smooth. Top coating: After the anti-corrosion layer is cured, use a polishing machine to remove burrs, and evenly apply a layer of fabric resin. Add 3% air hardener to the resin. Inspection standards and acceptance: Provide raw material certificates and inspection reports. The inner wall treatment shall be inspected according to the medium concrete base treatment. Inner surface inspection: The inner surface should be smooth and smooth, with no impurities, no exposed fibers, and no visually visible cracks and delaminations. 3. Metal surface pretreatment: Use electric grinding wheels, wire brushes, emery cloth and other tools to grind and remove rust on the tank and cone back cover. If the tank is severely rusted or has oil stains, use sandblasting to remove rust. Pickling or sandblasting (quartz sand) primer putty: Apply epoxy resin primer. Reinforcement layer laying: After the primer is dry, use hand lay-up method. The glass cloth must be trimmed. The glass cloth should be soaked and compacted. The seams should be staggered not less than 1 layer of epoxy resin glass cloth + 1 layer of structural resin chopped strand mat. Alternate layers with layer structure resin cloth. The lining layer is laid out: one layer is lined with resin glass cloth + one layer is lined with resin chopped strand mat + one layer is lined with resin surface felt. After the glue is dry, apply a layer of paint (/lining resin). The lining resin and surface coating are food-grade resin. The lining of iron cans generally has a service life of 3 years and must be used continuously, otherwise it is easy to bulge.
FRP anti-corrosion refers to making FRP on the surface of carbon steel, concrete or other base materials to prevent the base materials from being damaged or deteriorated by the media or environment.
