Rotary Vane Vacuum Pump for Marble

Marble is a metamorphic rock formed by the original rocks in the crust through the action of high temperature and high pressure in the crust. The internal force of the crust promotes the process of qualitative changes in the original various types of rocks. The marble is very beautiful when polished.

This article tells about the marble vacuum glue repair method. What role does the rotary vane vacuum pump play in this process? And what are the steps of vacuum glue repair. 

Marble Application  

Marble is mainly used for processing into various shapes and plates, as the walls, floors, platforms and columns of buildings, and is also commonly used in monumental buildings such as monuments, towers, statues, etc. Marble can also be carved into arts and crafts, stationery, lamps, utensils and other practical works of art.  

The marble vacuum glue repair method can ensure that the gap between the marble and the gas existing in the glue can be removed by repeated vacuum treatment by the general rotary vane vacuum pump, so that the combination of the glue and the gap is the most compact, so as to ensure the firmness of the finished product to the greatest extent. This can effectively extend the service life. 

Marble Characteristics  

  1. Not deformed

After long-term natural aging, the rock has a uniform structure, a very small linear expansion coefficient, and the internal stress completely disappears without deformation.  

  1. High hardness

Good rigidity, high hardness, strong wear resistance, small temperature deformation.  

  1. Long service life

No need to apply oil, not easy to stick to fine dust, easy to maintain and long service life.

There will be no scratches, it will not be prevented by constant temperature conditions, and it can maintain its original physical properties at room temperature.  

  1. Not magnetized

It can move smoothly during measurement, without stagnation and astringency, and is not affected by moisture, and the plane is well-defined.

Marble Vacuum Glue Repair Steps 

  1. Use a high-pressure water gun to clean and dry the marble surface and the interior of the cracks

  2. Prepare the vacuum box and install two sets of 5.5KW rotary vane vacuum pumps on the vacuum box

  3. Inject glue at the cracks on the marble surface

  4. Put the glued marble into a vacuum box for vacuum treatment, and extract the air from the cracks of the marble and the glue layer to further compress and penetrate the glue layer.

  5. Take out the marble, inject glue again at the crack and repeat the vacuum treatment until the glue layer no longer sinks and penetrates.

  6. Grind and polish the glued marble.

The use of rotary vane vacuum pump glue repair process can become very simple, and at the same time effectively eliminate the waste phenomenon when marble is used as a building material. In addition, compared with other pumps, the rotary vane vacuum pump has the following advantages:

  1. Easy to use, easy to install and maintain

  2. The rotary vane vacuum pump is equipped with gas ballast valve, which can extract a small amount of water vapor

  3. The ultimate vacuum degree of the rotary vane vacuum pump is high

  4. Built-in forced oil feeding, sufficient lubrication and reliable performance

  5. Pump is equipped with automatic oil non-return valve

  6. No oil leakage, no fuel injection, no pollution to the working environment
