Causes of damage to glass-lined vacuum dryers and repair methods

Glass-lined vacuum dryer is a very important equipment in the chemical production industry. When it is in use, some damage will inevitably occur. At this time, the staff should repair it in time, so let's talk about the glass-lined vacuum dryer. Causes of damage and repair methods
  1. Reasons for damage

  1. The base material is unqualified.
  2, processing stress is damaged.
  3. Poor enamel quality.
  4. Thermal stress damage.
  5. Mechanical damage.
  6. Hydrogen evolution corrosion.
  7. Electrostatic puncture.

   Two, repair method
  (1) Re-calcining the glass lined:
  1. This is a traditional equipment repair method, and it is also a way to solve the problem. The general repair period is about 30 days, which is relatively long and the cost is very high, so the repair process is more complicated.
  2. Before recalcining the glass-lined glass for the vacuum dryer, you need to remove the previous glass-lined and trim the inner wall smoothly, so the thickness of the steel plate will become thinner. This method can only be used once or twice.
  3. At the same time, the equipment has to be returned to the manufacturer for processing, so the production line needs to be stopped, which will cause a lot of losses.
  (2) Glass-lined repair agent:
  1. In contrast, this method is more economical and practical. It uses various glass-lined repair agents to repair the damaged parts on the glass-lined dryer.
  2. When operating, only need to remove the problematic part, and polish the surrounding smoothly to avoid incomplete repair.
  3. Reuse glass-lined repair agent to fill in or use polymer materials to complete the de-porcelain, perforation, corrosion and other problems of glass-lined equipment.
4. The entire repair period only takes about one day, and the cost depends on the size of the wound surface. Due to the small workload, the vacuum dryer can quickly restart production. It is currently a repair method adopted by many chemical companies. .
  5. What needs to be reminded is that repairing the dryer with this method may cause problems again soon, or it will not solve the fundamental problem.
In the working process of glass-lined vacuum dryer, it will come into contact with some chemical materials, many of which are corrosive. This is the main reason that the equipment will be damaged. What our staff has to do is to repair them in time and fundamentally Solve the problem.
