1. What are the disadvantages of choosing manual rust removal versus laser rust removal?
The common method of manual derusting is to gently wipe or pull the reinforcement back and forth on the sand pile with a steel wire brush, sand pan, sack cloth, etc. The effect of this cleaning is OK for the time being. Wait a long time. Passivation will occur. It will return to its original appearance. It can't meet everyone's needs at all. It's very simple for everyone to do it over and over again. Real numbers are troublesome and unnecessary.
2. What are the disadvantages with chemical derusting?
Steel derusting agent is a kind of steel derusting material mixed with a and B components. It is made of a variety of components. It is not safe to use than other steel derusting agents, and serious rust can be removed in a short time. It can temporarily restore the original color of the metal, without damage to the base metal in a short time, and can clean the rust on the surface of the reinforcement. It can also work in fine cracks. The effect can be achieved at room temperature. However, the treated metal surface will have an impact on electroplating and painting, and also affect the binding force of reinforcement. Scope of application: rust scale, iron filings and rust slag of equipment made of cast iron, carbon steel, alloy and other materials. Dissolve metal oxides. Method of use: the reasonable concentration and cleaning time should be selected according to the corrosion degree, thickness and other factors. Component a can be diluted by 2-6 times. Component A is a concentrated formula. For floating rust, dilution of more than 20 times will have a good effect. Soaking, dipping, brushing, spray, forced circulation, ultrasonic cleaning can be used. This product can effectively penetrate into the rust layer and dissolve stubborn oxides, sediments, slag scales, etc. Apply it to the rusted metal surface for a few minutes to temporarily expose the true color of the metal. Then wash the derusting reinforcement with clean water, and then brush (or soak, dip, spray) component B liquid on the metal surface.
3. Laser cleaning machine
The so-called laser cleaning machine refers to the automatic removal of rust through cold drawing and straightening process for wire rods and reinforcement with fine diameter; The coarse steel bars are derusted with a disc wire brush derusting machine. There are two types of laser derusting: fixed and mobile. Generally, it is self-made by the reinforcement processing unit, and the power drives the disc wire brush to rotate at a high speed to remove the rust on the reinforcement. Fixed laser derusting is generally installed with a disc steel wire brush. In order to improve efficiency, the two methods can also be used together.
