What are the types and functions of electrostatic floor in the computer room?

Anti-static floor is also called dissipative static floor. Square tube stool is a kind of floor. When it is grounded or connected to any lower potential point, the charge can be dissipated to the resistance of 10 to 5 to 10 of 9 The characteristics between the secondary ohms are characteristic. "GB50174-2008 Electronic Information System Room Design Specification", page 20, section 8.3.1, specifies that the surface resistance or volume resistance of the anti-static floor or floor should be 2.5×10~1.0×10Ω.

First, the category of electrostatic floor:

1, ceramic anti-static floor

The anti-static ceramic tile is used as the surface layer, the composite all-steel floor or the cement particle board, and the surrounding conductive strips are edge-sealed (the ceramic floor without the strip is easy to drop the porcelain when it is bumped). It has the advantages of stable anti-static performance, environmental protection, fire prevention, high wear resistance, high service life (more than 30 years of service life), high load capacity (average load of 1200kg/m2 or more), waterproof, moisture proof, good decorative effect, etc. Class room. The disadvantage is that the floor itself is heavier (15kg or more on a floor), which has a certain impact on the load on the floor; in addition, professional installation workers are required to install it, otherwise it will be unevenly installed.

2, all steel anti-static floor

(non-standard type and national standard type)

It is made of high wear-resistant melamine HPL fireproof board or PVC as the surface layer (the northern part is dry due to the anti-static floor of the whole steel, it is not easy to use HPL fireproof board veneer), the steel shell structure substrate, and according to whether there is black strip There are also borderless and edged points.

The advantage of the all-steel floor is that it is convenient to construct, there is no gap problem after installation, and the replacement is convenient. The disadvantage is that the surface layer material is not wear-resistant, the service life is short, and it is easy to pick up the skin angle, and it will be replaced in a few years.

3, aluminum alloy anti-static floor

The product adopts high-quality cast aluminum profile, and is stretch-formed. The surface layer is made of high wear-resistant PVC or HPL veneer, and the conductive adhesive is adhered. It has the effect of permanently using the substrate without rust, thus effectively solving the composite floor. And all steel floor product defects, but tailor-made high-end anti-static floor, but its cost is too high.

Second, the role of anti-static floor

1. Eliminate the danger of cable exposure to the human body.

2. The adjustability of the anti-static raised floor can be utilized to eliminate the unevenness of the real ground and ensure the overall level of the ground of the machine room.

3. It can leak static electricity to the ground and reflect electromagnetic radiation. What is an anti-static floor? Anti-static floor is also called a dissipative static floor. It is a floor that, when grounded or connected to any lower potential point, dissipates the charge and is characterized by a resistance between 1.0x105-10Ω. What are the effects of static electricity on computers? The anti-static technology of computer rooms is part of the security and protection of computer rooms. Static electricity generated for a variety of reasons is one of the most frequent and difficult to eliminate. Static electricity not only causes random failures, malfunctions or operational errors in the operation of the computer, but also causes breakdown and destruction of certain components such as CMOS, MOS circuits, and two-stage circuits. In addition, static electricity has a significant impact on the external equipment of the computer.

A display device with a cathode ray tube, when subjected to static electricity, may cause image disorder and blurring. Static electricity will also cause Modem, network card, Fax, etc. to work abnormally, and the printer's wiring is not smooth and other faults. The problem caused by static electricity is not only difficult for hardware personnel to detect, but sometimes software personnel mistakenly believe that it is a software failure, which causes work confusion. In addition, when static electricity is discharged through a human body to a computer or other device (so-called fire), when the energy reaches a certain level, it also gives a feeling of electric shock.
