Standard Requirements for Museum Cabinets

The required standard for museum display cabinets

The appearance of the cabinet should be coordinated with the design of the relevant exhibition hall and the form design style of the showcase. The appearance process should be clearly noted. The appearance, surface material and size should be clearly reflected in the design drawings.

Museum cabinet has good security, stable structure, safety, with good anti-theft and anti-damage performance; Opening mode to meet the exhibition layout and security requirements, easy maintenance.

Museum cabinet has good airtight; The environmental quality, such as humidity, pollutant concentration and lighting, must meet the requirements for the environmental control of the corresponding cultural relics.

The seller can provide cabinet, glass, lighting and other physical materials as acceptance materials.

1. Appearance requirements

Display cabinet should be combined with the exhibition hall design, and the overall style of the exhibition hall coordination, visual effect is good.

The appearance of the display cabinet is straight and straight, the surface is smooth and flat, the layer color is the same, no scratches, bare bottom, deformation and other obvious defects.

Lock function design should be safe and reasonable, the keyhole is hidden.

2. Technical standards

Exhibition cabinet structure and internal materials

Frame structure: The whole of the showcase is metal structure, do rust treatment. No less than 1.2mm rectangular square pipe welding molding, using independently developed U-shaped groove, special aluminum alloy aluminum edge; The skeleton should be made of metal profiles with high hardness. After automatic CNC cutting plate punching and bending forming, fusion welding and other processes are adopted. The surface decoration coating is processed by high-temperature dust-free electrostatic spraying process. Steel plate specification is 1250mm×2500mm(national standard); The overall structure should be modular design, the appearance is smooth, no uneven phenomenon, surface flatness <0.1mm/m, each part of the size and diagonal error <0.5mm/m; Solder joint diameter ≤5㎜, convex point ≤0.1㎜; After welding perpendicularity shall not be greater than ±1°/m, weld uneven ≤1㎜; Dimensional tolerance ≤±0.5㎜, right Angle error ≤±0.5㎜.

Display glass and process: The display case adopts 6+0.76+6mm, 5+0.76+5mm laminated safety domestic ultra-white glass (selected according to the final configuration scheme of the display case). The laminated film of super white glass should adopt the technical standard, the thickness of 0.76mm PVB board, the transmittance is not less than 95%. Glass flatness deviation ≤±0.5mm/m; Side bending deviation ≤±0.5mm/m; Square deviation is less than 0.5mm per 1m diagonal; After bonding, the size error of each part is less than 1mm/m. The joint of glass and glass reaches 45° hypotenuse tool shadowless adhesive bonding. There must be no glue marks, no bubbles, the bonding strength is greater than the glass itself. Glass adhesive should adopt brand, and bond firmly, beautiful, high transparency.
