How to make laminated glass, how to separate laminated glass

At present, there are two main production methods for it; Film method (dry process) and grouting method (wet process), but at present dry production is the mainstream, classification of laminated glass:

1. Bulletproof glass is a combination of multiple pieces of transparent flat glass of different thicknesses and multiple pieces of PVB film, which has high toughness when the bullet comes into contact with the glass.

Their impact may be weakened to a very low degree or zero, so they cannot penetrate, and generally bulletproof glass can be used as military defense, bank counter guard glass, gold and silver jewelry and other valuables display cabinets, etc.

2. Explosion-proof and anti-theft alarm glass, which is a transparent and high-strength glass, which cannot be destroyed with simple tools, can effectively prevent the occurrence of theft.

It is usually made of glass made of multiple layers of high-strength organic transparent material and glued layer material, and in order to impart early warning performance, wire mesh can also be sandwiched into the glue layer.

And buried with visible light, infrared, temperature, pressure and other sensors and alarm devices. It is mainly used in bank vaults, warehouses, cultural relics warehouses and exhibition cabinets, valuable commodity counters, etc.

3. Fireproof glass. It is a new type of functional material for construction. It has good light transmittance and fire retardant performance. According to the characteristics of the production process, fireproof laminated glass can be divided into composite fireproof glass and infusion fireproof glass.

Laminated glass is a combination of glass with polyvinyl butyral (commonly known as PVB) film sandwiched between two or more pieces of glass, which is firmly bonded into one after heating and pressurization, and when the laminated glass is suddenly broken by the impact of external force, the glass fragments are stuck by PVB film, and the cracks are radial, which can basically maintain the original shape and visibility, and can avoid glass punctures, scratches, and smashing due to the fall of glass, which is a kind of safety glass.

Dry lamination refers to the use of solid PVB (polyethylene butyral) film in the middle of the glass; Wet lamination is made by blending and curing liquid glue. However, there are also two methods of wet lamination, one is heated and baked with a special furnace, and the other is formed by sunlight (using ultraviolet light)! The former has a much smaller bubble generation rate than the latter.

Technology available on-site...Five, seven, seven, eight, two, seven, six, six.

Summary. 1. The laminated glass can be soaked in dibutyl ester for 30 hours (the ambient temperature above 20 degrees) can separate the glass.

2. It can be separated in the factory (provided that it is tempered dry lamination). Evenly heats the glass through the line. When it reaches 200-300 degrees, watch the glass film soften and break it with something, and immediately use cold water to cool down the local film after breaking, and tear off the film, but note that if the cooling is too fast, it can't be torn off, and if the cooling is slow, it will be hot and will be pulled off, so pay attention to safety when operating.

Hope it helps.

How do you separate laminated glass?

1. You can soak the laminated glass in dibutyl ester for 30 hours (the ambient temperature of 20 degrees is good to talk about volts or more) to separate the glass. 2. It can be separated in the factory (provided that it is tempered dry lamination). Evenly heats the glass through the line.

When it reaches 200-300 degrees, watch the glass film soften and break it with something, and immediately after breaking it, UF brings cold water to cool down the local film, and tear off the film, but pay attention to if the cooling is too fast, it can't be torn off, and the cooling will be hot and will be pulled off. Hope it helps.

This can't be done, is there a better way.

This answer is there, it's still early, press it with your finger, if the fingerprint clearly appears in the middle of the feast, it is the glass; Scrape it with a nail, and what there is no trace is glass; Write with a mile pen, it is more difficult to wipe clean and build auspicious spirits is to know the loss.

I can use dilute hydrochloric acid.

Dear, I'm glad to answer for you: how to separate laminated glass? A: Hello, dear! <>

There is no way to separate laminated glass or insulating glass, there is no way to separate laminated glass, and insulating glass can be peeled off with a blade on the side stove. Or heat to soften the glue and cut it with a knife. The surface is covered with PVB film, covered with another piece of tempered glass of the same size, and enters the initial press, which is a semi-finished product.

Increase the temperature of the initial press a little, slow down the speed a little, put the finished product in, and when you come out, the hidden sedan car will open with something to pry two pieces of glass, 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. Thank you for your patience.

The above is my full reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best! Peace and joy!

Laminated glass is a type of glass that is composed of two or more pieces of glass, which are then injected with an interlayer and then made by a special process.

The advantages of laminated glass are: 1. As a current decoration, it can play a very good sound insulation effect, because there is an interlayer film in the middle of the laminated glass, which can play the role of isolating sound, which is more suitable for office installation and maintains the quiet and comfortable office.

2. It also has the function of filtering ultraviolet rays. The sandwich glass is composed of multiple layers of glass, which can block ultraviolet rays and protect people. If it is used for home installation, it blocks ultraviolet rays, and can also play a protective role in some valuable furniture in the home to prevent the furniture from fading and deforming.

3. Nowadays, many doors will also be installed with laminated glass, such as kitchen doors, replaced by laminated glass, the kitchen smoke is not easy to accumulate on it, and it will be very clean and tidy.

4. There are some lively and active bear children at home, if the laminated glass is installed in the home, it will also be very beneficial, to avoid glass breakage and harm to children, and it can play a good role in protecting children.

5. The laminated glass is vacuum, which can prevent the spread of fire and play a certain protective role in the event of a fire.

To put it bluntly, it is a transparent adhesive for glass. For example, the aviation five-layer windshield is ...... by temperature resistance, electric heating and defrosting, impact resistance, and heat preservationbonded into a monolithic transparent glass.

The main thing is that you should pay attention when pouring glue, the preparation is complete, the temperature is well controlled, and it is generally avoided. There is another reason, it is very likely to be the problem of glue, many people think that all glue can be used to make laminated glue that is wrong, you must use a special laminated glue, here I can recommend it, Shanghai Sunrise Meilan decorative glass ****, they launched a wet laminated glue, you can teach the technology for free, if there is still a problem with the steam bag, you may wish to ask them.

Laminated glass film and glass need to be dry and clean.

1.Whether air enters during glue filling, there are bubbles.

2.Be sure to wash and blow dry.

3. The temperature should be well controlled.

You have to pay attention to every link.

Laminated glass production process: LED glass, also known as photoelectric glass, power glass, is a perfect combination of LED light source and glass, and breaks through the traditional concept of building decoration materials. The pattern can be designed inside the glass in advance, and the controllable changes can be realized through DMX all-digital intelligent technology in the later stage, and the brightness and darkness and changes of the LED light source can be freely controlled.

The interior is completely transparent wire, which is different from ordinary wires, and no lines can be seen on the glass surface; After the special treatment in the later stage, both the technical requirements and the safety requirements have reached the relevant national certification standards.

The difference between dry production and wet production of tempered laminated glass is the process, in fact, "dry lamination", "wet lamination" are in line with national standards, in the "Safety Glass Compulsory Certification Inspection Implementation Rules" stipulates: the types of intermediate layers (film dry method, grouting method, en film, etc.) are OK, mainly because the vast majority of wet laminated levels are too poor, very easy to yellow, blistering, delamination and other problems, so that enterprises dare not use.

There are 2 ways to produce laminated glass:

1.Dry lamination: pre-press 2 or more pieces of high-quality glass with PVB or EVA in the middle, and then enter the autoclave at about 130 degrees under the pressure of the left and right pressurized bubbles in the middle of the middle layer of film to bond 2 pieces of glass.

2.Wet lamination: A chemical mixture (methyl ester, dibutyl ester, etc.) is poured between two pieces of glass to solidify the bonded glass under UV-catalyzed or thermal polymerization conditions.

The above two processes are mature processes, with large investment, high output and stable quality in dry process; Small investment in wet process, flexible and convenient operation;

Glass + Film + Glass.

Then put it in an autoclave for 24 hours.
