Example Embodiment

[0020] In order to make the object of the present disclosure, the technical scheme of the present disclosure is clear and complete, and the present disclosure is clearly described in order to maintain the following description of the present disclosure, the present disclosure omits the known function. And detailed description of known parts to avoid unnecessarily confusing the concept of the present invention.

[0021] Bridge support process for improving corrosion resistance, as follows:

[0022] S1, the methyl vinyl ether, tetrafluoroethylene and perfluoride, is placed in a mesh, and adding sulfate, sulfate, sulfite, diisopropyl carbonate, etc. Inorganic or organic peroxide is initiator, sodium phosphate is pH adjusted, and ammonium perfluoroctate is a surfactant.

[0023] S2, the mesh first mixes methyl vinyl ether, tetrafluoroethylene and perfluoride ether, and various additives, and countless loose particles are extruded into the gap of the fitting particles and penetrate to ...

Abstract

The invention relates to the technical field of bridge supports, and discloses a bridge support treatment process for improving corrosion resistance, which comprises the following steps: S1, putting methyl vinyl ether, tetrafluoroethylene and perfluoroalkene ether into an internal mixer, and mixing uniformly; adding inorganic or organic peroxides such as persulfate, persulfate-bisulfite, diisopropyl peroxydicarbonate and the like as initiators, sodium dihydrogen phosphate as a pH value regulator and ammonium perfluorooctanoate as a surfactant, and carrying out internal mixing; according to the bridge support treatment process capable of improving the corrosion resistance, the surface of a bridge support is wrapped with a layer of rubber, and the rubber has good high and low temperature performance, does not deform in the quick temperature change process, has excellent resistance and has low permeability to gas and liquid and good combustion resistance; therefore, the bridge support is wrapped in this way, and a good protection effect can be provided for the bridge support.

Description

technical field [0001] The invention relates to the technical field of bridge supports, in particular to a bridge support treatment process for improving corrosion resistance. Background technique [0002] The bridge bearing is an important structural component connecting the upper structure and the lower structure of the bridge. It is located between the bridge and the pad stone. It can reliably transfer the load and deformation of the bridge upper structure to the bridge lower structure. It is an important force transmission device of the bridge. . There are two kinds of fixed bearings and movable bearings. The commonly used bearing forms in bridge engineering include: asphalt felt or flat bearing, plate rubber bearing, spherical bearing, steel bearing and special bearing, etc. [0003] At present, the bridge bearing generally adopts the plate rubber bearing, and the plate rubber bearing is a kind of bridge bearing product made of multi-layer natural rubber and thin stee...
