Guangzhou tempered glass factory, the difference between laminated glass dry clamp and wet clamp
Release time:
Oct 17,2024
The difference between the dry clip and the wet clip of the laminated glass is mainly reflected in the production process, intermediate materials, performance characteristics and application scenarios. The following is a detailed analysis of the difference between the two:
1. production process is different
Dry clamping: dry clamping glass production process is relatively complex, mainly in the two pieces of glass between a layer of polyvinyl butyral (PVB) as the main component of the intermediate film. Through the process of high temperature and high pressure, the PVB film is closely combined with the glass to form a strong adhesive layer.
Wet clip: The production process of wet clip glass is to pour synthetic resin and other glue between two pieces of glass, and then solidify the glue under the conditions of sun light, ultraviolet lamp baking or natural drying, so as to bond the two pieces of glass together.
2. intermediate materials are different
Dry clamping: the intermediate layer of dry clamping glass is a whole piece of PVB film, uniform thickness, good toughness and adhesion.
Wet clip: The middle layer of wet clip glass is synthetic resin and other glue, its thickness may not be as uniform as PVB film, and it is easily affected by environmental factors (such as yellow degumming caused by ultraviolet radiation).
3. performance characteristics are different
Dry clip:
High safety: Even if the glass is broken, the fragments will be stuck to the PVB film and will not fall off and hurt people.
Strong penetration resistance: The toughness and adhesion of the PVB film make the dry clamp laminated glass have a high penetration resistance.
Good stability: the process of dry clamping laminated glass is complex, the quality of the finished product is stable, and it is not easy to burst and other problems.
Wet clip:
The safety is also high: after the glass is broken, it will not cause splashing, but the phenomenon of yellow degumming is more under long-term use, and the anti-aging performance is poor.
There are many types of glue that can be clamped: there are many types of glue that can be clamped in wet glass, there is no restriction on the size, and the selection range is large.
Sound insulation and thermal insulation performance: wet clip laminated glass also has certain sound insulation and thermal insulation performance, but may be slightly inferior to dry clip laminated glass.
4. application scenarios are different
Dry clamp: Due to its high safety and stability, dry clamp laminated glass is more suitable for places with high safety performance requirements, such as sightseeing elevators, high-rise building exterior walls, etc.
Wet clip: Wet clip glass because of its many types of glue, no restrictions on the size and other characteristics, more suitable for some places with certain requirements on the cost, such as household railings. However, it should be noted that in the environment of direct sunlight or strong ultraviolet rays, wet clip laminated glass may turn yellow and degumming, so it is necessary to carefully choose the use scene.
In summary, there are significant differences in the production process, intermediate materials, performance characteristics and application scenarios of the dry and wet clips of the laminated glass. When choosing, it should be considered comprehensively according to specific needs and scenarios.
