Prevulcanized butyl rubber sheet is an efficient and convenient repair material, which is widely used in the repair of chemical equipment lining. This rubber sheet has excellent corrosion and wear resistance, and can effectively cope with various damage and aging problems of chemical equipment lining.
The use of pre-vulcanized butyl rubber sheet for repair can not only improve the service life of the equipment, but also reduce maintenance costs and improve production efficiency. Compared with traditional repair methods, pre-vulcanized butyl rubber sheet has better adhesion and temperature resistance, and can maintain stable performance in various harsh environments.
At the same time, the pre-vulcanized butyl rubber sheet also has good chemical resistance, which can resist the erosion of various chemicals, ensuring that the repaired equipment lining has a long service life. Therefore, pre-vulcanized butyl rubber sheet is an indispensable and important material in the maintenance and repair of chemical equipment.
The specific process of repairing the lining of chemical equipment with pre-vulcanized butyl rubber sheet.
1. Preparation stage.
Before the repair can begin, a thorough inspection and assessment of the damage to the lining of the chemical plant is required. This includes accurate documentation and analysis of the size, shape, location, and extent of the injury. At the same time, it is also necessary to understand the overall structure of the equipment lining in order to formulate a suitable repair plan.
Second, the cleaning stage.
After the damage is confirmed, a thorough cleaning is required. Impurities, dirt and residues are thoroughly removed from the surface of the equipment lining to ensure that the pre-vulcanized butyl rubber sheet adheres well to the surface of the equipment lining. At the same time, the surface of the equipment lining needs to be sanded to increase the adhesion of the pre-vulcanized butyl rubber sheet.
3. Paste stage.
After the cleaning is complete, the pre-vulcanized butyl rubber sheet is applied to the damaged part of the device's lining. When pasting, it is necessary to ensure that the rubber sheet fits perfectly to the surface of the equipment lining, free of air bubbles and gaps. At the same time, it is also necessary to pay attention to the thickness and size of the rubber sheet to avoid being too thick or too thin.
Fourth, the pressurization stage.
After the pasting is completed, the pre-vulcanized butyl rubber sheet needs to be pressurized. Pressurization increases the adhesion of the rubber sheet to the surface of the equipment lining, ensuring the stability and durability of the repair. When pressurizing, it is necessary to pay attention to the amount and time of pressure to avoid overpressure or underpressure.
Fifth, the curing stage.
After the pressurization is complete, it needs to be cured. Curing is the process of making the pre-vulcanized butyl rubber sheet bond more strongly to the surface of the equipment lining. During curing, attention needs to be paid to temperature and humidity control to avoid adverse effects.
Sixth, the inspection stage.
After curing, a thorough inspection of the repaired site is required. The inspection includes visual inspection, air tightness inspection, pressure resistance inspection and other aspects to ensure that the effect of repair meets expectations. If any problems are found, they need to be adjusted and fixed in a timely manner.
7. Closing stage.
After passing the inspection, the restoration work can be completed. Clean up the site, organize tools and materials, and carry out the necessary protection and identification of the restoration site. At the same time, the entire remediation process needs to be summarized and evaluated in order to improve the remediation effect in the future.
The above is the specific process of pre-vulcanized butyl rubber sheet to repair the lining of chemical equipment. It is important to note that the repair protocols and specific steps that may be required will vary depending on the equipment and the damage situation. Therefore, in practice, it needs to be adjusted and optimized according to the specific situation.
