Embodiment approach

[0042] A method for implementing a corrosion-resistant composite membrane for a long-term corrugated plate tunnel rockburst prevention device, comprising the following steps:

[0043] 1) Select SD360 nanofiber tunnel special primer, SD320 nanometer tunnel special potential adjustment paint, curing agent and organic solvent;

[0044] 2) Substrate surface pretreatment before film formation:

[0045] A. The corrugated steel surface substrate is subjected to surface blasting treatment;

[0046] B. Jet abrasive derusting reaches Sa3 level, and special parts are polished and derusted by power tools to St3 level;

[0047] C. The surface is required to be clean and dry during construction, and all visible grease, oil, dust, lubricants and other pollutants must be removed;

[0048] D. The construction surface must be cleaned repeatedly before each paint application, keep ventilation, and keep the inner wall dry;

[0049] 3) The surface cleanliness meets the above surface requirement...

Embodiment

[0058] The study of the corrosion environment and corrosion characteristics in the tunnel provides a design basis for the design of the anti-corrosion composite membrane for the new long-term corrugated plate tunnel anti-rock burst device. The scheme design, material selection, formula, performance, process and treatment method of the anti-corrosion composite membrane of the new long-term corrugated plate tunnel anti-rock burst device, using the super acid-resistant, alkali-resistant and salt-resistant functions of nano-anti-corrosion materials, in the new long-term corrugated plate The surface of the anti-corrosion composite film of the anti-corrosion device of the plate tunnel rockburst device forms a nanofiber high-performance heavy-duty anti-corrosion "metal-plastic" composite film protective layer, which makes it have a long corrosion resistance of acid, alkali, salt, water vapor and harmful substances, and adapts to The special tunnel corrosion environment in the tunnel c...

Abstract

The invention discloses a long-acting corrugated plate tunnel anti-rockburst device corrosion-resistant composite film and an implementation method. According to the long-acting corrugated plate tunnel anti-rockburst device corrosion-resistant composite film and the implementation method, SD360 nano-fiber tunnel special primer is applied to the bottom layer for 6-7 layers, the total thickness of a dry film of the SD360 nano-fiber tunnel special primer is 400 microns, SD320 nanometer tunnel special potential adjusting paint is applied to the surface for one layer, the total thickness of a dry film of the SD320 nanometer tunnel special potential adjusting paint is 80 microns, and the total thickness of the long-acting corrugated plate tunnel anti-rockburst device corrosion-resistant composite film is 480 microns; and the corrosion-resistant composite film has ultra-strong acid resistance, alkali resistance, salt resistance and resistance to corrosion of water vapor and harmful substances and is suitable for a special tunnel corrosion severe environment in a tunnel so as to achieve a 100-year long-acting protection effect, the anti-aging property of the material is improved, the unprecedented high-performance anti-corrosion capability and functional stability are achieved, the effects of being non-toxic, harmless, odorless and environment-friendly are achieved, and the health of constructors is protected.

Description

technical field [0001] The invention belongs to the technical field of chemical nanocomposite membranes, and in particular relates to a corrosion-resistant composite membrane for a long-term corrugated plate tunnel anti-rockburst device and an implementation method. Background technique [0002] Tunnel engineering has the advantages of overcoming height difference, reducing driving distance, and improving driving safety. At the same time, it can save ground land and play a role in protecting the environment. Tunnel engineering is playing an increasingly important role in my country's transportation infrastructure construction. [0003] With the increasing buried depth of tunnel engineering, many hard rock tunnels pass through areas of high ground stress, and the problem of rockburst cannot be ignored. Rockburst is a dynamic instability phenomenon that occurs in high-in-situ stress areas of hard rock. The elastic strain energy accumulated in the rock mass itself is released s...
