Strictly control the pH value of large roll galvanized wire bath, research shows that the size of the bath pH value directly affects the quality of steel wire coating, improper control of pH value will cause loose coating. When the pH value is greater than 3, the steel wire coating has burr caused by fine dendrites, and the surface is not smooth. The current density is strictly controlled. From the microscopic morphology, the higher the current density, the larger the zinc layer grain deposition, the less dense the corresponding zinc layer.

In addition, galvanized silk manufacturers can be required to passivation treatment after zinc immersion, after passivation treatment of zinc has a better anti-discoloration effect, can effectively extend the time of discoloration, the combination of the two, discoloration should be able to solve.

Paint on the galvanized layer, the binding force between each other and the baking temperature of the paint has a great relationship, after galvanized coating alkyd paint, adhesion is no problem. Galvanized amino paint, paint adhesion is not good. Do two bottom two surface, adhesion is ok, if the two bottom two surface to two bottom three surface, that is, more paint, more baking once, again test adhesion is very poor, poor to the paint from the galvanized layer of pieces torn off.

With other coatings, the opposite is true. Rust builds up immediately and spreads quickly underneath the coating, causing it to peel. The depletion of zinc in the atmosphere is very slow, about 1/17 to 1/18 of the corrosion rate of steel, and is predictable. Its life span far exceeds that of any other coating. The life of the coating depends on the thickness of the coating in a particular environment. And the coating thickness is determined by the thickness of the steel, that is, the thicker the steel is easy to get thicker coating, so the thick steel part of the same steel structure must also get thicker coating, in order to ensure a longer life.

There is no adhesion test of powder spraying or fluorocarbon spraying on packaged galvanized wire, but there are two points for reference: first, in sealed or air-free environment, non-metallic volatiles can corrode zinc coating; Second, zinc at higher than 230 degrees (c) will cause the matrix metal brittle. And powder spraying and fluorocarbon spraying are to be baked at a higher temperature and in a sealed environment, causing rapid corrosion of zinc, resulting in loose corrosion film resulting in coating adhesion decline, and even lead to (matrix) steel wire brittle situation may exist.

Third, positive and negative twisting barbed rope appearance is beautiful

1. First, you will need to locate the power steering pump and the steering gear on your 98 Chevy truck. The power steering pump is usually located near the front of the engine, while the steering gear is typically located on the driver's side of the vehicle.

Having your power steering hose continuously blow off can be frustrating and concerning. Power steering is an essential component of your vehicle as it helps make steering easier and more precise. When the hose keeps blowing off, it can make driving unsafe and could potentially cause further damage to your vehicle.

5. With the clamps or fittings removed, carefully pull the old power steering hose out of its connections and out of the vehicle. Be sure to dispose of the old hose properly, as it may contain power steering fluid.
