How maintenance and upkeep of the room antistatic flooring
2012-08-18 Reads : 60
I. General Provisions An anti-static raised floor floor construction includes primary treatment, mounting brackets, beams, braces, and installing grounding system, laying floors, construction, testing and quality inspection. 2, the construction site, the temperature should be between 10 --- 35 degrees Celsius, relative humidity less than 80%; should be well ventilated. Second, materials, equipment and tools 1, the construction materials shall meet the requirements. No special requirements on the design should meet the following requirements: anti-static floor board should be flat, solid plate and the adhesive surface should be solid and should have a wear-resistant, moisture, flame-retardant properties. Brackets, beams, bracing surface should be flat, smooth steel shall be galvanized or other rust treatment. The anti-static performance and mechanical properties, appearance and quality shall comply with the requirements of anti-static raised floor ventilation specification SJ/T10796. Should be stored in ventilated and dry warehouse, away from acids, alkalis and other corrosive substances is strictly prohibited in the outdoor sun and rain. 2, the construction should have the equipment and tools, including cutting machine, hand-held saws, suction cups, 1M steel ruler, spirit level, cleaning waxing machine, the test electrode and test instruments, such as its specifications, performance and technical indicators should be consistent with the requirements of the construction process. Third, preparation of construction 1, the construction should be done the following preparations: familiar with the design and construction drawings and surveying the construction site. The development of the construction program, drawing anti-static ground, grounding system diagram, grounding terminal diagram and ground network layout. Gather a variety of construction materials, equipment, utensils, and inspection. The elimination of the construction site, equipment, and inspection. Completely remove the residues of the quality of the project construction site dust, sand and gravel. The works of more than 140 square meters, should be kind of laying. The construction site shall meet the following requirements: grass-roots ground concrete floor, terrazzo or other hard surface, the surface should be smooth, rugged to be patched. For new construction projects, civil construction should be a default grounding device. Works within an area of ??100 square meters of 1-2 ground terminal. For the reconstruction project of the old plant, the same requirements should be based on the actual situation to determine the location and quantity of ground terminal. In the interior decoration work has been completed on the installation with the primary device is fixed at a predetermined position, pipes or wires placed under the raised floor has been laid in place only after the anti-static raised floor installation, not the upper and lower cross-operation. Fourth, the construction procedure Carefully check the ground roughness and wall verticality, and found significant deficiencies or require partial reconstruction, should be addressed to the Party the relevant departments; 2, horizontal pull, and floor installation height of the ink lines projected into the wall to ensure that after the laying of the floor at the same level, measure the interior length, width, and select the reference position, and on the ground pop-up installation supports network grid to ensure that the laying neat and beautiful, while minimizing the floor of the cutting; 3, to install bearings adjusted to the same desired height and bearing placed the cross at the intersection of grid lines on the ground; 4, the mounting screws will truss beam fixed on the bearing, and the level of foot, rectangular device one by one correction truss, so that both in the same plane, perpendicular to each other; 5, with Blister in the assembled truss placed on the raised floor; 6, close to the wall at the remaining size is less than the length of the floor of the cutting floor and pieced together; 7, laying floor, with blisters on the level meter-by-block leveling, the height of the raised floor of rely on adjustable bearing adjustment, should be light in the laying process light, to prevent scratching the floor and damage to the side while laying edge cleaning to avoid the debris, dust left on the floor below; 8, the engine room set up heavy equipment can be installed in the floor under the equipment base bearing to prevent deformation of the floor; 9, HPL decorative sheet cutting or opening processing, its opening concave corner system φ6 ~ φ8 only hole to prevent surface cracking after processing floor coverings. |
Clean the ground Draw grid lines
Stent placement To adjust the level
Beam connection Installing the floor
Floor Edge Clean the floor surface
Five, testing, quality inspection1, the raised floor ground detection equipment used: digital megger: test voltage of 100V, range should be greater than 1.0X103 - 1.0X1011 ohm; accuracy class shall not be less than 2.5. Electrodes: two, copper, the surface shall be chrome-plated, cylindrical, supporting the use of digital megger for testing anti-static surface of the ground resistance and the system resistance. Measuring electrode pads: dry and conductive sponge or conductive rubber, since the volume resistivity should be less than 1.0X103 ohms. The grounding resistance measuring instrument used to measure earth electrode resistance between the earth ground. Its range and accuracy class must meet the measurement requirements. Ruler: the length 2M, used to check surface flatness. Anti-static performance testing apparatus shall be within the validity period of the measurement identification.
2, the test ambient temperature should be between 15-30 degrees Celsius, the humidity should be less than 70%.
3, the test electrode at one end resting on the floor surface. Another test electrode and the ground terminal connection
4, the quality assessment method should be (batch inspection sampling procedures and sample forms) of GB2828 provisions
5, the electrical performance of anti-static floor board should meet the following requirements:
System resistance: less than 1.0X106 ohms static conductive type, static dissipative for 1.0X106-1.0X1010 ohm, static dissipative 1.0X105-1.0X1010 ohm (measurement of the distance between electrodes 900 - 1000MM) system grounding resistance should meet the design requirements.
6, anti-static floor board cover layer should be soft and smooth, uniform color, should not bubble may not have obvious defects; board adhesive should be firm, there should be no open plastic phenomenon.
