How to separate tempered laminated glass?

A piece of tempered glass.

Put it on the machine, spread PVB film on it, cover it with another piece of tempered glass of the same size, enter the primary press, and come out as a semi-finished product. Increase the temperature of the initial press a little, slow down the speed a little, put the finished product in, pry two pieces of glass when you come out, and then put it in water to soak for 48 hours, and the film will fall off with a light lift.

Laminated glass is a composite glass product made of two or more pieces of glass with one or more layers of organic polymer interlayer film sandwiched between them, and after special high-temperature pre-pressing (or vacuuming) and high-temperature and high-pressure process treatment, the glass and the interlayer are permanently bonded into one composite glass product.

Commonly used laminated glass interlayers are: PVB, SGP, EVA, PU, etc.

In addition, there are some special ones such as color interlayer laminated glass, SGX printed interlayer laminated glass, XIR low-E interlayer laminated glass, etc. Decorative and functional laminated glass such as embedded decorative parts (metal mesh, metal plates, etc.), laminated glass with embedded PET materials, etc.

A piece of tempered glass, placed on the machine, spread PVB film on it, cover with another piece of tempered glass of the same size, enter the initial press, and come out is a semi-finished product.

You raise the temperature of the initial press a little, slow down the speed a little, put the finished product in, pry two pieces of glass with something when you come out, and then put it in water to soak for 48 hours, and the film falls off with a light lift.

Summary. Distinguish between tempered glass and ordinary glass:

1.Check the product factory certificate, pay attention to the CCC mark and number, factory date, specifications, technical conditions, and enterprise name.

2.Wear polarized sunglasses** glass, tempered glass should show colored striped spots.

3.The flatness of tempered glass will be worse than that of ordinary glass, and there will be a concave and convex feeling when you touch the surface of the tempered glass by hand. Observe the longer edge of the tempered glass, there will be a certain curvature. Put two larger pieces of tempered glass next to each other, and the curvature will be more pronounced.

4.If you look at the glass under the light, the tempered glass will have bluish spots.

1. First of all, there is a certain difference between the two in terms of sound insulation effect, and through the comparison of relevant experiments, the sound insulation value of the three-layer glass must be slightly larger. Both layers of glass can hear the noise from the outside indoors, and the decibel level is slightly larger, so there is a certain difference in sound insulation. 2. There are also differences between the two in terms of thermal insulation.

Usually in cold cities, it is recommended to use three-layer glass, because with one more layer of glass, the heat transfer will become poorer, and the thermal insulation performance will naturally be better. In some normal temperature cities, you can choose single glass or double glazing. 3. There will definitely be a difference between the two in terms of **, if you choose three-layer glass, the budget will be more, and the production cost of double-layer glass will be less, so it will be cheaper.

The method of judging tempered glass from ordinary glass to the naked eye can be:

1. Carefully observe the edge of the glass, generally speaking, there is no small gap in tempered glass, even if there is one, it feels "softer" than the notch of ordinary glass when touched by hand, and ordinary glass often has a certain small gap on the edge, and the gap is sharp.

2. According to the standard glass, if it is ordinary glass, the scenery through the ordinary glass is very clear, and the scenery seen through the tempered glass is a little "deformed" (the distance between the person and the glass is about 2m, and it will be more obvious to see the distance), this is because the tempered glass needs to be softened in the processing process, so that it will have a small degree of deformation.

3. Hard objects (such as pliers, iron parts, etc.) can be used to scratch the edge of the glass, and ordinary glass is more empty and fragile than tempered glass.

The water pressure on the underwater glass is a long-term load, so the fatigue effect of the glass should be considered. The fatigue effect can cause a significant reduction in the strength of the glass. The results show that the stress state of underwater glass is related to the position of the glass installation, the support mode of the glass and the shape and area of the glass.

The force on the bottom glass is equal everywhere, that is, the action of "equal distribution of load", while the force state of the side glass is proportional to the depth, that is, the action of "triangular load".

There are two types of glass support: three-sided support (fixed) and four-sided support (fixed). The shape of glass can be divided into two types: rectangular and round. Due to the differences in these parameters, different calculation methods and correction factors must be used.

Even if the water depth is the same, they are subjected to different forces under water, so we must design and check the design before ordering glass. Based on the calculations, the maximum bending stress and maximum deflection of the glass sheet can be determined. Considering the safety factor, the flexural strength of tempered glass must be less than 500kg cm, and the maximum deflection of the glass plate surface shall not be greater than 1 200 of the span.

Laminated glass generally refers to laminated glass. In the middle of the two layers of glass is glue, which is used to glue the two layers of glass together.

Some people also call insulating glass laminated glass, after all, the middle is empty and layered.

So you have to see if the middle of your glass is empty to determine whether it is hollow or laminated.

Safety glass is a kind of glass that does not break after severe vibration or impact, and is not easy to hurt people even if it is broken. It is used for doors and windows of automobiles, airplanes and special buildings, etc. The use of safety glass in the building is resistant to bullets or debris from hurricanes of 100 kilometers per hour, which is of particular importance for modern buildings with main glass structures.

Common types of safety glass include film glass, tempered glass, laminated glass, etc.

Tempered glass: It belongs to safety glass. Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass, and the glass first counteracts the surface stress when it bears external force, thereby improving the bearing capacity and enhancing the wind pressure resistance, cold and heat resistance, impact and so on.

Insulating glass: It is a high-performance sound and heat insulation glass made of two pieces (or three pieces) of glass, using a high-strength and high-air-tightness composite binder, and bonding the glass sheet with an aluminum alloy frame containing desiccant. Insulating glass is a glass product that evenly separates two or more pieces of glass with effective support and is bonded and sealed around the perimeter, so that a dry gas space is formed between the glass layers.

Its main materials are glass, aluminum spacer, corner bolt, butyl rubber, polysulfide glue, and desiccant.

Laminated glass: Laminated glass is made of two or more pieces of glass sandwiched with strong PVB (ethylene polymer butyrate) film under high temperature and high pressure, or EVA (ethylene vinyl acetate copolymer) film through high temperature vacuuming. It is a kind of safety glass.

This is normal, because the cost of non-tempered laminated glass is higher than that of tempered glass in terms of process and material.

1 Tempered laminated glass should be packed in containers, container racks or wooden boxes. Each piece of glass is wrapped in plastic or paper, and the glass is filled with a light and soft material that is not easy to cause visual defects such as glass scratches. Each packing box should be marked with the words "facing up, gently moving and placing up, careful breakage, glass thickness, grade" and so on.

2. Tempered laminated glass can be transported by various types of vehicles, when transporting, the wooden box shall not be placed flat or obliquely, the length direction should be the same as the direction of movement of the conveying vehicle, and there should be rainproof measures. When the glass is transported, it should avoid contact and collision with hard objects, and the tempered laminated glass that is not used temporarily should be stored vertically in a dry and ventilated room.

3. When tempered laminated glass, it is a glass product with internal stress, which can no longer be cut, drilled and edging after forming, otherwise it will cause bursting, and the edge stress concentration of tempered laminated glass should be well protected. Do not hit the edge of the glass with a sharp and hard object, otherwise it is easy to burst the glass.

4. Before the installation of tempered laminated glass, high temperature exposure, high humidity and rain should be avoided, the glass at the construction site should be stored in a ventilated and dry place, and the construction personnel should check the site in time when encountering sudden weather changes and heavy rain, so as to prevent the glass packaging box from being soaked in water and causing water seepage and discoloration at the edge of the tempered laminated glass.

5. When installing underwater glass, it is necessary to ensure that the waterproof and leakage performance of the whole system is good. First of all, the parts that come into contact with the water must be made of waterproof materials. Secondly, for the space between the glass and metal frame, it must be completely filled with sealing materials such as polysulfide glue or silicone rubber with good sealing.

The installation design and construction operation shall comply with the requirements of the national mandatory industry standard JGJ 113-97 "Technical Regulations for the Application of Architectural Glass".

Tempered laminated glass, also known as tempered laminated glass, is a kind of laminated glass, which is compounded by 2 layers or more than 2 layers of ordinary float glass after tempered bridge treatment. The middle layer is mostly PVB film (scientific name polyvinyl butyral), which is a kind of safety glass that is bonded together by two or more layers of glass through a special process of heating and high pressure.

Tempered laminated glass not only has the characteristics of tempered glass with greater resistance, but also has the characteristics of ordinary laminated glass, even if the glass is broken, the fragments will be glued together due to the action of the intermediate glue layer. It effectively prevents the occurrence of debris falling incidents and ensures personal safety.

Tempered Changmeng laminated glass is a special laminated glass product made of tempered glass based on limb bridges and then glued. It not only has the characteristics of high strength of tempered glass, but also inherits the excellent safety performance of laminated glass without fragments falling off. Tempered laminated glass is suitable for installation in places with special safety requirements, such as protective windows of high-rise buildings, glass curtain walls, glass roofs, etc., and underwater glass places that have been subjected to a certain amount of water pressure for a long time.
