Quanpin Machinery teaches you the preparation work before installation of glass-lined equipment

1. Use and damage

  Glass-lined equipment is widely used in the chemical industry. The glass-lined glaze layer attached to the surface of the iron tire is smooth and clean, extremely wear-resistant, and its corrosion resistance to a variety of inorganic and organic substances is unmatched by stainless steel and engineering plastics; glass-lined equipment has the mechanical strength of general metal equipment, It also has the characteristics that ordinary metal equipment does not have: preventing material deterioration and discoloration, avoiding metal ion pollution, and low price, convenient and practical. Therefore, glass-lined equipment is the first choice for fine chemical industries such as pharmaceuticals, dyes, and food processing.

  Since the glass-lined lining is a brittle material after all, and the harsh working conditions do not allow any tiny cracks in it, special care is required during the transportation, installation and use of the equipment, and care must be taken to maintain it. Ensure the safe use of equipment.

  Even so, the damage to the glass-lined equipment still exists due to the following reasons:

  1. Improper transportation and installation methods;

  2. Hard objects such as metal and stones are entrained in the material to hit the wall of the vessel;

  3. The temperature difference between hot and cold shock is too large, exceeding the specified requirements;

  4. Strong acid and strong alkali materials corrode under high temperature and high concentration conditions;

  5. Overload use under abrasive conditions.

  In addition, there are also factors such as improper foreign body removal methods and poor enamel layer quality. Through investigation and investigation of companies that use glass-lined vacuum dryer equipment, it is found that damage is found, and it has to be disassembled and transported to its manufacturer to rebuild the enamel layer. This method not only has serious waste, but also affects production. Especially in today's equipment prices are greatly increased. Therefore, with the increasing application of glass-lined equipment, it has become necessary to find a simple and quick repair technology for glass-lined lining, and ceramic metal glass-lined repair agent (glass-lined reactor repair agent) has emerged at the historic moment.

  II. Titanium alloy repair technology

  The repair agent is easy to use, mainly according to the following five steps:

  1. Surface treatment to remove the deposits on the corroded parts, use an angular or straight grinder to polish the parts to be repaired, the principle is "the rougher the better", and finally use acetone or alcohol to clean and degrease (no hands or objects are allowed touch).

  2. Ingredients Pour the base material and curing agent on the working plate according to their proportions, and mix them thoroughly to become a dark rubber material.

  3. Paint

  ①Spread the prepared r-shaped material evenly on the surface of the repaired part with a rubber spatula, scrape to remove bubbles, ensure that the surface is in close contact with the repair agent, and cure at 20-30 ℃ for 2 hours.

  ②Use a tool to brush the matched s-shaped material on the surface of the r-shaped material. Generally, it is required to apply two coats with an interval of more than 2 hours. Pay attention to the current distribution.

  4. Curing at 20 ℃-30 ℃, 3 to 5 hours can be machined, and it takes more than 24 hours to fully cure. If the coating thickness is high, the curing time can be shortened.

  5. Processing can be used to distinguish the knocking sound to check the curing effect. Used tools should be cleaned with detergent immediately.

  The use of titanium alloy repair agent on enamel equipment has a very good effect. Its simple and practical performance not only saves a lot of manpower and material resources for your company, but also brings considerable economic benefits.

  3. Titanium alloy glass-lined metal repair agent (glass-lined equipment repair agent):

  Titanium alloy glass-lined repairing agent (glass-lined equipment repairing agent) is a polymer alloy repairing agent, mainly used for repairing local damage to the surface lining of glass-lined equipment and its parts. The characteristics of the repair agent for glass-lined vacuum dryers are not only its high abrasion and corrosion resistance, but also the rapid repair ability of the repair agent for glass-lined equipment. Glass-lined equipment repair agent can almost quickly repair damaged equipment at room temperature on site without stopping the production line. The glass-lined equipment repair agent is magnetic but non-inductive, and the maximum use temperature of the titanium alloy glass-lined repair agent can reach 196 ℃.
