Water-based nickel electromagnetic shielding coating

&Water-based nickel-based electromagnetic shielding paint
Water-based nickel-based electromagnetic shielding paint is a new type of electromagnetic wave shielding paint with good shielding performance. It uses nickel powder with excellent antioxidant properties as the main filler, and the shielding effect of the action layer can reach b Above, it has strong stability. The content of volatile organic compounds (C) and free formaldehyde in the coating is low, and the coating has good ductility, which can prevent electromagnetic leakage due to wall cracking. At the same time, the coating has good matching performance with ordinary latex paint and does not affect the normal decoration of the interior walls of the building. After testing by the Information Security Evaluation and Certification Center of the Chinese People's Liberation Army, the Electronic Industry Safety and Electromagnetic Compatibility Testing Center, and the National Chemical Building Materials Testing Center, all indicators of the coating have reached relevant national and military standards. It is suitable for electromagnetic wave shielding protection in command centers, computer and precision instrument rooms, communication centers and other buildings. Painted buildings can not only improve their ability to resist information leakage, but also prevent them from being affected by external electromagnetic interference.

Coating composition and packaging&The coating is a one-component self-curing coating, packed in plastic barrels. Net
Construction method: ) Base layer treatment: In order to obtain better conductive continuity to prevent electromagnetic leakage, the surface treatment of the building is very important. Depending on the material of the building's surface base, different treatment methods should be adopted.
)Concrete and cement mortar base concrete base mainly includes cast-in-place concrete, precast concrete, aerated concrete, cement mortar, mixed mortar and cement asbestos board base. The base treatment of this type of material must meet the following requirements:
Strong, that is, no cracking, no powder loss, no emptying, no peeling, no lime bursting points, and no old coatings with poor adhesion.
Smooth, that is, the surface is flat, the elevation is vertical, the yin and yang angles are vertical, square and there are no missing edges or corners, and the lattice seams are of the same depth and horizontally and vertically.
& Clean, that is, there is no dust, no laitance, no oil stains, no rust spots, no mildew spots, no salt precipitates, no moss and other impurities on the surface. Dry, the moisture content of the base layer should not be greater than %
The base layer value should not be greater than
B) Gypsum and various masonry clay brick layers. For base layers of this type of material, it is recommended to do the following treatments for the ground and walls. The specific requirements are as follows:
Remove the original wall skin from the wall, and apply the interface agent together (except for the new wall).
Moisten the wall with water, millimeter thickness: use mud-water mortar as a primer to remove the lint
Millimeter thickness: sweep the cement mortar (with a layer of nylon mesh cloth inside)
& a layer of plain cement (with a layer of construction adhesive inside)
&mm thickness: compact the cement mortar surface to catch the light (requirements Level)
& The ground is first compacted with plain soil, and the compaction coefficient is &. (not used above the second floor)
mm thick C pisolite concrete
Plain cement first (internal reference construction adhesive)
Millimeters thick: water-mixed mortar is compacted, smoothed and polished (requires smooth, medium-coarse sand)
& Painting can be done by brush or roller. During construction, try to ensure that the coating is evenly thin and thick, without leakage or sagging, and reaches the specified thickness. Immediately after painting, the paint film is magnetized with a magnetized rod, and the distance between the magnetized rod and the paint film is kept within centimeters. The magnetized paint film will naturally form a film after drying at a temperature of about ℃ for 10 minutes. The amount of paint used is calculated in /㎡ (one coat), the paint thickness is &/ coat, and four coats are enough.
After each painting, water should be available to clean the painting tools in time for next use.
Notes: The storage period of paint is one month.
Please store paint in a cool, dry and ventilated place.
Unused paint should be sealed and stored to prevent moisture from evaporating and solidifying.
