Construction process of ceramic anti-static floor

Now there are many kinds of market floor, there are wooden, anti-static, different materials of the floor, floor construction process is not the same, then ceramic anti-static floor construction process is what kind of?

Ceramic anti-static flooring, also known as the tile anti-static floor, is the use of anti-static ceramic tile surface, attached to the steel floor board base or composite plate based on (particleboard, particleboard, calcium sulfate cement plate) and a frame into high floor. Because of the pavement is beautiful, durable, service life is significantly better than the other veneer flooring, and ceramic anti-static flooring is widely used in various high-grade room, bank room, telecommunications room, senior accounting monitoring room, microelectronics device production workshop, can also be used in the advanced intelligent office building.

Construction technology of ceramic anti-static floor:

1. contact layer should use the volume ratio of 1:3 dry cement mortar, thickness should be 25 to 35 mm, appearance should brush a cement slurry.

2. anti electrostatic tile floor project should include the construction of the bottom layer, contact layer, surface layer and anti-static grounding system.

3. in cement mortar contact layer, should be in proportion to participate in resistance reducing agent. The component ratio of cement mortar and conductive powder is 1:0.003.

4. the floor of the cement mortar should be clean when the anti-static cement tile is laid on the cement mortar connection layer. Between the plate and the plate, it is necessary to plan the demand setting. The plate should be closely bonded to the wall, and no mortar caulking shall be used.

5. paving should adhere to standards in place, with a rubber hammer to tap and mortar tight, and adjust its surface flatness and width of 3mm).

6. lay in the cement mortar layer is provided with conductive contact strip, the longitudinal distance should be 600 mm, lateral distance should be between 3000 to 4800 mm. After the completion of the laying, should use the multimeter to test the composition of all copper conductive pathways, and do the shade project acceptance record.

The 7. plate type, pointing should be used with the same strength grade, the same color cement or other high-quality materials and maintaining pointing, and maintenance. Pointing in the factory building, should use no dust pointing information.

8 the ground paved with ceramic tile should be flat, straight and inlaid correctly. The floor and the link layer should be posted tight, no empty drum.

The 9. section of the gap width should be consistent with the planning requirements. When the plan is not compliance on time, gap width is not greater than 3 mm.

10. after the anti static ceramic tile laying, the surface should cover the fabric and adhere to the wet, maintenance time should not be less than 5d. When the compressive strength of cement mortar in contact layer reaches the requirement, clean water or 3% ~ 15% oxalic acid or neutral detergent solution can be used to clean the surface.

11. after the floor surface is boring, the grounding connection should be carried out according to the demand.

12. the outdoor grounding part of the electrostatic grounding system should be made into independent grounding; for the places without conditions, it can be connected to the grounding bus. The number of grounding electrodes depends on the geological conditions of the soil, and the outdoor grounding resistance should not be greater than 30 ohms.

13. when the electrostatic grounding and lightning protection grounding, DC operation grounding, grounding and safety communication operation maintenance ground share a ground, should be less than 1 ohm system grounding resistance, and the lightning protection grounding branch, electrostatic and other grounding lightning protection device should branch sensitive resistor, to ensure safety.
