Corrosion depth test method for PVC highly-dense viscous steel wire grid

Abstract

The invention relates to a corrosion depth test method for a PVC highly-dense viscous steel wire grid. The method includes the steps that firstly, a sample to be tested is installed at the top of a test cavity liner and fixed through fixing bolts, a sulfuric acid solution is put into an evaporator and a liquid storage tank, a valve is switched on, an electric heater is started to heat the evaporator, liquid in the evaporator boils and then generates corrosive gas, the generated corrosive gas enters a test cavity through finned heat exchange tubes arranged in a steam heater, redundant corrosive gas in the test cavity enters a recovery device through an air outlet, and liquid condensed on the test cavity liner enters the recovery device through a liquid discharge port, wherein the controlled temperature of the electric heater is 100-150 DEG C, the controlled temperature of the steam heater is 80-160 DEG C, and a calcium hydroxide solution with the mass concentration of 10% is used for treating waste liquid and tail gas. The method provides a fast, simple and convenient test means for studying the corrosion mechanisms of various steel wire grids and evaluating corrosion-resistant steel wire grid materials.

Description

technical field [0001] The invention relates to a performance test of a steel wire grid material, in particular to a method for testing the corrosion depth of a PVC high-density viscous steel wire grid. Background technique [0002] Eco-grid technology is a multi-hinged grid that weaves anti-corrosion, wear-resistant, high-strength low-carbon heavy galvanized, aluminum-coated or galvalume-coated steel wires with mixed rare earths, or homogeneous steel wires coated with polymers. , hexagonal mesh or ribbed mesh, and then cut and assemble the mesh into structural units such as solid cages and green mats, and fill the interior with stones and other fillers, as the basic components of the building, after strict design calculations , forming a safe and stable cross-sectional structure, which is used for protection projects such as bank slopes, embankments, and roadbeds.

Problems solved by technology

[0003] Polyvinyl chloride (PVC) has the characteristics of high strength and good formability. It is often used as the polymer material coated on the surface of the steel wire in the ecological grid technology to improve the corrosion resistance of the ecological grid. It is subject to corrosion, sunlight and abrasive wear for a long time, and it has corrosion resistance. Once corrosion occurs, it is easy to cause perforation of the steel wire grid in a short time, damage to the ecological grid, and cause safety hazards
