Identification method of dimming glass;
Identification method of dimming glass: 1, transmittance
Good quality dimming glass, with excellent light transmittance when powered on, clear and transparent, beautiful appearance, light transmittance but light impermeability when powered off, can protect privacy well. Simple test method:? Put your palm on the back of the glass. When the power is off, look at the palm on the back from the front. Although you can see its vague back, you can't see the fingerprints of the palm. Or an object can be placed at 10cm according to the front glass. It is best not to look at objects from behind when the light on both sides is balanced and the backlight is not bright. Generally, the light transmittance of good quality dimming glass should be above 74%.
Identification method of dimming glass: 2. Sandwich movies.
For dimming glass used for non-indoor purposes such as bathroom partition, internal and external curtain walls, doors and windows, the manufacturer should ask whether the intermediate film of dimming glass is EVA interlayer or PVB interlayer. At the time of purchase, you can ask the manufacturer for the certificate of intermediate film to prove whether to use EVA film or PVB film (to prevent profiteers from using EVA film to trick consumers into using PVB film). If you use PVB film, you should ask for the certificate of origin of PVB brand to judge whether it can be used in the corresponding field (all friends familiar with the glass industry know). Generally, curtain wall glass and outdoor laminated glass will not use EVA film as the intermediate film, because EVA is easy to yellow, age or even delaminate under the conditions of sun exposure or high temperature and humidity; Moreover, because of the poor logarithmic viscosity of EVA and the low impact strength of laminated glass products, it is generally abandoned by curtain wall manufacturers.
Identification method of dimming glass: 3. panel
Consumers can choose to use the corresponding glass panel according to the functional requirements of glass in the application field. For example, tempered glass should be used as dimming glass panel in public buildings, bathrooms and outdoor curtain walls with high safety factor, fireproof glass should be used as panel for customers with high fire protection requirements, and curved glass should be used as panel for places that need bending.
Identification method of dimming glass: 4. Glass size
The technical strength can be judged according to the glass width provided by the manufacturer. The production of dimming glass film is a highly technical and difficult activity. The larger the size, the more difficult it is to produce. Therefore, many domestic manufacturers require some orders whose width exceeds the maximum size of their dimming film to be spliced in blocks. As we all know, for dimming glass, if a number of glasses with very narrow widths are spliced together, it will be visually ugly. For example, the width of 1.4m can be selected, and two pieces of 70cm glass should not be spliced, which will easily affect the visual beauty and practicality (when used as a projection curtain wall, when multiple pieces of glass are spliced, there will be many seams in the middle, which will have a poor impression. )。 At present, the largest dimming glass in the world can reach 1500mm×3300mm.
Identification method of dimming glass: 5. Hollow and fixed.
If the dimming glass needs to be hollowed out and fixed, ask the manufacturer in advance to see if it can dig holes, because the average ordinary manufacturer or new manufacturer can't meet the requirements, so ask in advance if you have relevant experience or can do it to avoid some unnecessary troubles and losses.
The identification method of dimming glass is here. At present, dimming glass is rare in home decoration, because the price of dimming glass is relatively high, so keep your eyes open when choosing, and don't cause losses to yourself.
