Anti-static flooring installation construction design specifications and points Anti-static flooring prices
Anti-static floor is also called dissipative static floor. It is a kind of ground decoration material with special functions. It is also one of the main building materials for building anti-static ground. It is mainly used in commerce, such as factory floor, various communication rooms, microwave communication, and medical treatment. , chemistry and many other fields. Anti-static floor is a highly functional floor type. It has dust-proof, fire-proof, moisture-proof and anti-corrosion functions. It is generally used in places with high dust and power requirements, such as computer room, medical, chemical, post and telecommunication hubs, and computer-controlled military, economic, national security, aviation, aerospace and traffic command and dispatch and information management centers. . The installation and construction of anti-static flooring is more complex than ordinary flooring, and many conditions are required to be complied with. Therefore, the design specifications and points for anti-static floor installation are the basic knowledge that every design and construction personnel must master.
First, anti-static floor installation design specifications
The anti-static floor is grounded or connected to any lower potential point, allowing the charge to dissipate, characterized by a resistance between 10 5 to 10 9 ohms. Because in the "GB50174-2008 electronic information system room design specification" for the anti-static floor installation construction design made a clear specification: anti-static floor or ground surface resistance or volume resistance should be 2.5 × l0 4th power ~ 1.0 ×10 of the 9th power ohms.
Second, anti-static floor installation design points
1. The fire protection level of the anti-static raised floor shall comply with the requirements of the "Code for the Fire Protection of Interior Decoration for Buildings".
2, anti-static raised floor height should be based on the use requirements.
(1) For wiring only: The basic size is 250mm.
(2) For alignment and air-conditioned air storage: The basic size is 400mm. The detachable plates of the floor can be interchanged and have high production accuracy to ensure the required sealing of the floor space when used as an air conditioning wind storage.
3, anti-static equipment room floor pavement construction is the final stage of construction and renovation. Should be completed in the indoor ceiling board laying, ceiling lighting, vents are also installed, clean the floor, paving and moving floor (with insulation cotton and trunking should first be covered with insulation cotton and trunking).
4. The floor of the anti-static machine room is laid on the cement mortar cushion that has been leveled. To reduce the height of the ground practice, when laying directly on the structural floor, the structural floor requires a smooth surface, and the interface agent is sprayed to cure the concrete surface and make the floor Can not afford sand.
5, the floor surface should be soft, not slippery, wear-resistant, resistant to pollution.
6, after the installation of the floor must be grounded, otherwise it will not be anti-static effect.
Third, the main technical indicators of anti-static floor (ground)
Anti-static floor conductive properties: Surface resistance 10 of the 6th power - 10 of the 9th power ohmic body resistivity 10 of the 7th power - 10 of the 10th power ohm / cm;
Anti-static floor fireworks performance: not less than 1600 °C;
Anti-static floor wear resistance: 0.1g/1000 rpm;
Anti-static floor water absorption: <0.5%;
Anti-static floor cold extreme heat: 15 °C -105 °C;
Anti-static floor does not show obvious cracks after 10 cycles of quenching and cooling;
Anti-static floor bending strength: the average is not less than 27Mpa;
Anti-static flooring warpage: ± 0.5%;
Anti-static floor specifications: 600×600×10mm.
Fourth, anti-static floor prices
The price of ordinary anti-static flooring on the market is about 100 yuan per square meter. The price of a high altitude aluminum alloy antistatic floor is about 800 yuan per square meter. Such as: Chongqing overhead 750mm 600 * 600 * 40mm aluminum anti-static floor (A-level non-combustible) price of 810 yuan / square meter.
Yinchuan Zhongtian Anti-static Flooring Co., Ltd. 600*600*30/35 100
Shanghai Boding Flooring Co., Ltd. 600*600*30/35 200
Guangzhou Aoge Decorative Materials Co., Ltd. 600*600*30/35 1000
In summary, the design of the installation and construction of anti-static flooring has been elaborated. However, in the actual installation process, in addition to the relevant technical indicators can only be high or low, other aspects can be based on the actual situation of the construction site To make corresponding adjustments, it is necessary to use relevant knowledge flexibly according to actual conditions.
