Reasons for Impact Cracking of Rubber Lining Equipment and Methods for Rubber Lining Repair
Sep 13,2022
Precision machining high-speed mixed bed, also known as mixed ion exchanger, is a filtration water treatment equipment made of internal high-temperature vulcanized rubber plates welded by splicing carbon steel. After a certain service life, the rubber lining will experience aging defects. In addition, the defects in the rubber lining technology and equipment collision inspection process are also an important reason. If the rubber lining is damaged, the defects should be repaired in a timely manner. Otherwise, when the resin is regenerated, the acid and alkali solution will enter the metal matrix through the defects in the lining and the rubber parts, corroding and leaking, and even affecting the water quality indicators and equipment service life, and even causing the boiler system Major accidents such as cooling system and steam engine system.
With the increasing demand for modern storage and transportation, various storage tanks have been developed. However, ordinary storage tanks cannot meet the storage requirements for special liquids or raw materials, so rubber lined equipment is used. Excellent quality and reliable performance. It can be designed, selected, and manufactured according to different purposes to ensure its use.
The reason for the cracking of rubber lining equipment is due to encountering the rubber plate during installation. Due to the impact force exceeding the bearing range of the rubber plate, the rubber plate cracked. If cracks appear at the opening of the pipeline, it is caused by collision during lifting in place.
Below, we will introduce several rubber lining repair methods for rubber lining equipment:
1. Rubber lining repair
This method first needs to confirm whether the pre vulcanized rubber variety used meets the operating conditions of this equipment, and the repair method is basically the same as the original rubber repair process. Moreover, this method is relatively simple and suitable for repairing the lining of non compressed containers such as large equipment. However, the disadvantage of using this method is that metal and rubber can only be bonded with adhesive, which has low bonding strength and can also be used for repairing storage equipment.
2. Raw rubber lining repair
The purpose of using raw rubber as the lining material layer of equipment is to excavate the size of the damaged area, so that the raw rubber can be placed in the material area, and its area will be greater than the damaged area. Then provide subsidies for rubber lined equipment as required. It is vulcanization treatment, but during the vulcanization process, attention should be paid to various pressures and temperatures to prevent the original rubber from not being vulcanized. This repair method is very effective, but the downside is that steam is needed on site.
3. Quick rubber lining repair of rubber lining rod
This method is a convenient rubber lining repair method for rubber lining equipment, and is very suitable for repairing small rubber lining equipment. It can also be more convenient to clean damaged areas. We can cut off the repair rod and mix it by hand to block the damaged area, so that the rubber lined equipment can be put into use quickly.
