Anti static floor, also known as dissipative static floor, is a kind of floor decoration material with special functions. It is also one of the main building materials for building anti-static floor. It is mainly used in commerce, such as factory workshops, various communication rooms, microwave communication, medical treatment, chemistry and many other fields. Anti static floor is a kind of highly functional floor, which has the functions of dust prevention, fire prevention, moisture prevention and corrosion prevention. It is generally used in places with high requirements for dust and electricity prevention, such as computer rooms, medical, chemical, post and Telecommunications hubs, and computer-controlled military, economic, national security, aviation, aerospace and traffic command and scheduling and information management centers. The installation and construction of anti-static floor is more complex than ordinary floor, and many conditions and restrictions need to be observed. Therefore, the design specifications and key points for the installation and construction of anti-static floor are the basic knowledge that every designer and constructor must master

The installation and construction of anti-static floor is more complex than ordinary floor, and many conditions and restrictions need to be observed. Therefore, the design specifications and key points for the installation and construction of anti-static floor are the basic knowledge that every designer and constructor must master

I. code for design of installation and construction of anti-static floor

when the anti-static floor is grounded or connected to any lower potential point, the charge can be dissipated, which is characterized by a resistance between the 5th power of 10 and the 9th power of 10 ohms. Because gb50174-2008 code for design of electronic information system machine room has made clear specifications for the installation and construction design of anti-static floor: the surface resistance or volume resistance of anti-static floor or ground should be 2.5× The fourth power of l0 ~ 1.0× Ohm to the 9th power of 10

II. Key points of anti-static floor installation and construction design

1. The fire rating of anti-static raised floor should meet the requirements of code for fire protection design of interior decoration of buildings

2. The height of the anti-static raised floor should be determined according to the use requirements

(1) for wiring only: the basic size is 250mm

(2) for wiring and air conditioning hangar: the basic size is 400mm. The detachable plates of the floor can be interchanged and have high manufacturing accuracy, so as to ensure the sealing required when the floor space is used as an air-conditioning air storage

3. The paving construction of the raised floor of the anti-static machine room is the final stage of building decoration. After the indoor ceiling board is laid and the ceiling lamps and vents are also installed, clean the ground and pave the raised floor (if there is insulation cotton and trunking, lay the insulation cotton and trunking first)

4. The raised floor of the anti-static machine room is laid on the leveled cement mortar cushion. In order to reduce the height of the ground, when it is directly laid on the structural floor, the surface of the structural floor is required to be flat, and the interface agent is sprayed to solidify the concrete surface, so that the ground does not sand

5. The floor surface should be soft, non slippery, wear-resistant and pollution resistant

6. After the floor is installed, it must be grounded, otherwise it will not play an anti-static role

III. main technical indicators of anti-static floor (ground)

conductivity of anti-static floor: the 6th power of surface resistance 10 — The 9th power of 10 ohmic volume resistivity is the 7th power of 10 — 10 to the 10th power ohm/cm

anti static floor smoke and fire resistance: not less than 1600 ℃

anti static floor wear resistance: 0.1g/1000 rpm

anti static floor water absorption: < 0.5%;

extreme cold and heat resistance of anti-static floor: 15 ℃ - 105 ℃

no obvious cracks appear on the anti-static floor after 10 rapid cooling and heating cycles

anti bending strength of anti-static floor: the average value is not less than 27mpa

warpage of anti-static floor: ± 0.5%;

anti static floor specification: 600× 600× 10mm。

IV. price of anti-static floor

the price of ordinary anti-static floor in the market is about more than 100 yuan per square meter. The price of high-altitude aluminum alloy anti-static floor is about 800 yuan per square meter. For example, the price of Chongqing overhead 750mm high 600*600*40mm aluminum alloy anti-static floor (class a non combustible) is 810 yuan/square meter

Yinchuan Zhongtian anti-static floor Co., Ltd. 600*600*30/35 100

Shanghai boding floor Co., Ltd. 600*600*30/35 200

Guangzhou Aoge decorative materials Co., Ltd. 600*600*30/35 1000

to sum up, the installation and construction design of anti-static floor are described in detail, but in the actual installation process, in addition to the relevant technical indicators can only be high but not low, Other aspects can be adjusted according to the actual situation of the construction site, and relevant knowledge should be flexibly applied according to the actual situation
