Embodiment Construction

[0016] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0017] refer to Figure 1-2 The first step in the method of lining the surface of the profile with FRP is to derust and chamfer the profile. Sand blasting and rust removal must reach Sa2 level or power rust removal must reach St2 level, so that the metal surface should have anchor lines with a depth of 0.06mm. The edges of the profiles need to be rounded with a radius greater than or equal to 5mm. These two processes can make the resin more evenly and tightly coated on the surface of the profile.

[0018] The second step is to make an interface layer on the profile surface with SW984-M resin mixed with 1%-1.5% methyl ethyl ketone peroxide. Apply SW984-M resin evenly on the surface of the cleaned profile. After completion, let the SW984-M resin cure at room temperature until the surface is not sticky, then turn t...

Abstract

The invention provides a method for lining the surface of a profile with FRP, which belongs to the technical field of surface treatment and comprises the following steps: cleaning the surface of the profile; using SW984‑M resin to make an interface layer on the surface of the profile; using DM411 resin to make an intermediate layer on the interface layer ; Use glass fiber cloth or chopped strand mat to make an anti-corrosion layer on the middle layer. The surface layer of FRP obtained by this method has particularly excellent corrosion resistance, and has a long service life even in a highly corrosive environment.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a method for lining the surface of a profile with glass steel. Background technique [0002] FRP, also known as FRP reinforced plastic, is a composite material made of epoxy resin as a matrix and glass fiber as a reinforcement through a composite process. [0003] In chemical enterprises, especially in environments with strong corrosiveness such as acid and alkali, FRP-lined profiles, such as I-shaped steel beams, are widely used. FRP can optimize the mechanical properties of profiles and enhance the wear resistance and corrosion resistance of profiles. At present, most of the methods of lining the surface of the profile with FRP are to apply a layer of resin on the surface of the profile and then paste a layer of glass fiber cloth. The surface layer of FRP obtained by this construction method has general corrosion resistance and a short service life in a strong corros...
