    Custom Stainless Steel Signs With Designed Patterns For Signs


    Ferric chloride corrosion stainless steel sign

    • Ferric chloride corrosion stainless steel signage formula: ferric chloride, active agent, water. The Baume degree of ferric chloride in the formula should be kept at about 42, and the active agent is added 0.8-1.2 ml per liter of ferric chloride solution. The stainless steel underside of the formulation is smooth and smooth, with no black passivation film and pitting.
    • The factors affecting the corrosion of stainless steel by ferric chloride solution are as follows:

    a. The effect of concentration. Chemical Corrosion We also call the micro-battery corrosion, the more positive the redox potential, the faster the corrosion rate. As the concentration increases, the redox potential becomes positive and the corrosion rate increases. Industrial grade ferric chloride is not high in purity, and its redox potential is relatively negative. Only when the Baume degree reaches 42 or higher, the redox potential can meet the requirements of corrosion of stainless steel.
    b. Effect of pH on the corrosion rate in solution. The PH value is low, which is strong against the corrosion of stainless steel; the pH value is too high, and the ferric chloride is hydrolyzed into iron hydroxide precipitate, which loses the corrosion effect. The pH of the corrosive liquid used in production should be adjusted to a certain extent.
    c. Effect of the temperature of the corrosive solution. The higher the temperature of the corrosive liquid, the faster the corrosion rate. However, considering the resistance of the corrosion-resistant ink, the temperature should be controlled between 30--40 °C.

    • Stainless steel signs are strong and strong

    Stainless steel sign

    • The stainless steel sign is an advertising sign made of stainless steel as a material, through etching, polishing, polishing and other processes.
    • The installation of stainless steel signs is generally divided into plastic and nailing. The glue is directly bonded to the wall or other installation position with silicone or other glue. The nail is fixed to the wall with screws. Other installation methods are handled according to the site environment.

    Stainless steel sign making process

    • Metal corrosion signs are generally divided into three types: concave type signs, convex type signs and convex and concave words combined with signs. The basic requirements of corrosion signs: beautiful patterns, clear lines, appropriate depth, flat bottom, full color, even brushing, uniform surface color. Characteristics of corrosion signs: weather resistance and strong solvent resistance;
    • Even if the paint falls off, it still has the function of a nameplate. Stainless steel is a special material that has good resistance to atmospheric and fresh water media corrosion, and can be satisfactorily decorated by drawing, etching and polishing. However, stainless steel corrosion is much more difficult than copper and aluminum plates. The fastest corrosion method is electrochemical corrosion, also known as electrolytic corrosion. Since electrochemical corrosion causes the ink to fall off during sign corrosion, the sign is not suitable for electrochemical corrosion, especially fine patterns. We only choose chemical corrosion. Chemical corrosion can be roughly divided into two types: strong acid corrosion and ferric chloride corrosion. Due to the complex formula of strong acid corrosion, difficult maintenance, and a large amount of smoke, polluted air is harmful to the human body, and manufacturers without purification equipment cannot use it. Ferric chloride corrosion is simple to formulate and easy to maintain and regenerate.
