What is a high-quality museum glass showcase
In the gallery exhibition hall, we can see not only the large closets arranged along the walls, but also the central closets that are frequently placed independently in the middle of the exhibition hall. What they've in common, that is, facing the followership, is separated by glass. But there are also exhibitions, where the shows are frequently canvas oils and puppets, which aren't placed in the display case, but use safety lines and walls to control the distance between the followership and the shows.
It can be seen that the two styles of using glass display case and setting up walls have been established after the birth of ultramodern galleries, and have now come the tradition of gallery exhibitions. Using glass display closets to insulate the shows from the general terrain of the exhibition hall, on the one hand, it can avoid the followership's contact with the shows and avoid the threat of damage; on the other hand, it can produce a small terrain inside the exhibition closets, which can keep the shows in constant temperature and moisture. It's especially important for artistic bones of organic matter and essence.
What kind of display case glass is good?
There are two main evaluation pointers display and safety.
Flaunting property
As we all know, light passing through glass is bound to change. The so- called display is the nature of confluence between looking at the shows through the glass and looking at the shows directly. It can also be subdivided into two pointers light transmittance and reflection.
The glass of the show with high light transmittance will lose lower light through the glass, and the followership will feel that the glass is veritably clear. The glass of the show with high reflectivity is easy to reflect when the light enters the glass, and the followership can see the reflected figure from the glass, affecting the visual effect. Although the light transmittance ofultra-white glass is high, but the reflectivity isn't ideal, it's still easy to form a figure. At present, several domestic glass manufacturers can produce low reflection glass with a reflectivity of lower than 1, and there's principally no figure in the visit, which principally solves the problem of reflectivity.
Security
The glass of the museum display case isolates the shows from the terrain, so it must be firm. The so- called safety is the property of defying force through glass without breaking. It can also be subdivided into two pointers firmness and tone- explosion forestallment.
A retired peril to the safety of the gallery is that there are vicious stealers who directly smash the glass of the exhibition closets and take away the shows. At present, the vast maturity of galleries use tempered glass made of ordinary glass after rapid-fire heating to high temperature and invariant cooling, and its resistance to violent impact and bending has been greatly bettered compared with ordinary glass. at present, the glass of the exhibition press can be principally unbroken, and its firmness isn't the same as ahead.
But tempered glass has an changeable threat- tone- explosion, with a tone- explosion rate of about 1 ‰ to 3 ‰. Although it isn't high, it has brought some losses to the gallery.
The main factors affecting the tone- explosion of tempered glass are as follows
1. The lesser the toughening stress, the easier it's to explode.
2. The tone- explosion probability of glass is commensurable to the boxy power of the compass size of contamination patches.
3. The near the contamination is to the neutral subcaste of the glass, the easier it's to tone- explode.
4. The lesser the temperature change (or the uneven heating of the glass), the easier it's to explode.
5. The lesser the force on the glass, the easier it's to tone- explode, so the glass for the ceiling is more likely to explode than the perpendicular glass for the curtain wall.
6. For the same glass, the larger the volume, the lesser the probability of tone- explosion.
At present, the gallery's strategy is to use cement to bond two layers of inured glass together, which is called cement- filled glass, which can't only effectively reduce the miracle of tone- explosion, but also the glass fractions after tone- explosion are clicked and won't hurt the shows.
