Product Description: Laminating Glass with PVB Film Processing
1. The glass cutting, cleaning and processing
To begin with, precisely cutting the glass as required is of importance. In case of the bubbles occurred the cutting error must be less than 2mm. Then the well cut glass edge should be grinded and cleaned to remove the oil stains and the other defects. At last, the softened water must be used in the last period to get rid of the unqualified products due to the weak adhesion. After the above process, the clean glass can be dried and placed in the room temperature for future use.
2. Lamination
In the laminating room, the temperature should be kept in 15~25°C, the humidity 18%~40% , the environment clean and the equipment and employees tidy. The glass must lay flat and so should the film on it. Then lay the other piece of glass on the film. Drawing the film is forbidden during trimming the film. Besides, be assured that the film must be 2-5mm bigger than the glass and the trimming knife keep away from the glass lest the glass particles cause the bubbles on the edge of the laminating glass.
3. Pre-pressure exhaust
To get the well sealed edge, the air between the film and the glass needs to be pressed out of the laminated glass. Two methods are generally divided into.
a. Rolling exhaustion.
Firstly, Heat the well laminated glass up to 25~40°Cand put it into the first roll (the distance of each rolls are 1mm smaller than the thickness of well laminated glass with the pressure of 0.2~0.5MPa.), then put it into a thermo stated container to heat up to 60~80°C, and then get into the second roll (the distance of each rolls are 2mm smaller than the thickness of well laminated glass with the pressure of 0.3~0.5MPa).After getting out of the rolls, seal the four sides of the laminated glass with clear tape to get rid of the bubbles.
b. Thermo vacuum pre-pressing exhaustion
Put the laminated glass into a vacuum bag or vacuum rubber gasket, and then employ the cool pumping and heat pumping to press the air out. Tips: the decompression vacuum degree is beyond 650mmHg and the cool pumping temperature should be less than 25°Cfor 30~40 minutes; while in the period of heat pumping, the temperature should be 70~120°C for 30~60 minutes.
4. Molding in high pressure
Place the Pre-pressure exhausted laminated glasses vertically on glass bracket leaving the distance of each glass more than 5mm. After the glasses are put into the thermo container, sealing the door and raising the temperature to 65°C-85°C; Then raise the temperature and pressure at the same time. The temperature raising rate is controlled in 5°Cper minute, and the pressure in 0.06MPa per minute. When the temperature and pressure up to 120~140°C and 1.0~1.5MPa respectively, keep them for 30~60 minutes. After that, keep the pressure and lower the temperature to 45°C, at the same time, loose the pressure to the atmosphere pressure. Finishing the high pressure molding process, we can have the final laminated glass for usage.
Marks, packaging, transportation, storage and shelf life of Laminating Glass with PVB Film Processing
1).Marks: it should include the product name, specifications, lot number, production date, expiration date, plant address and the brand name.
2).The package: the pvb film is insulated with PE film, cased into an aluminum foil bag, then vacuum sealed, and lastly into wood box or card drum. There should be quality certificate, packing list in the package. The marks of moisture proof, shock proof and sunlight proof should be labeled.

4).Storage: the product should be stocked in clean warehouse and normal temperature. It is forbidden to leave it under direct sunlight. As for the broken or opened package, they should be stocked under temperature of 20°C±5°C and in relative humidity of 20%-40%.
5).Shelf life: under normal atmospheric temperature, if well-packaged, the shelf life can be 2 years.
- Q: What kind of material is plastic film in greenhouse?
- Multifunctional long-life filmMultifunctional long-life film is added in the process of aging of polyethylene material and amount of surfactants. Multifunctional film Zhejiang Xinguang plastic factory production, 7.5 meters wide, 0.06 mm thick, the service life of a times longer than ordinary film, other than the night shed material high 1 - 2 C. Moreover, the film is not easy to be filled with water drops, has good coverage effect, low cost and high benefit.
- Q: Build a fleshy plastic film greenhouses, where the best? Why?
- General is the use of non drip defogging the best. Recommend the use of Po film, as to the use of which manufacturers, generally near the can. Big picture or worry, I can try to help you.
- Q: What are the factors affecting the puncture strength of plastic film?
- A test piece with a diameter of 100mm is installed on the sample film fixing clamp ring. The steel needle with a diameter of 1.0mm and a top radius of 0.5mm is used. The top of the needle is driven at the speed of 50mm/min, and the maximum load of the steel needle penetrating the test piece is read. I hope I can help you.
- Q: Do I need to tear the plastic film of the barrel washing machine?
- Of course, wrinkling, housing, affect the appearance, but after the water into the middle membrane and shell, the film is not breathable, easy to cause the casing corrosion, which will be removed.
- Q: Why do plastic films undergo prepress?
- If you order a large amount of printing patterns, and physical patterns have little or no health, high security requirements, the choice of flexo, in addition should choose our country in gravure printing, gravure printing, so all kinds of talents on the gravure printing, auxiliary materials and consumables are mature, procurement is also convenient
- Q: Is it possible to lay a plastic film between the roof slab and concrete for waterproofing purposes?
- Sure。 In the construction, the film can not be worn out, the effect is good, and the waterproof life is very long. I've done this before, and the film was good until the concrete was removed from the house. "It's been used for ten years.".
- Q: Keyboard circuit board, film paper and rubber strip, how is it installed?
- The rubber strip is pressed on the outside of the film. Generally, the rubber strip is placed on the cover, then the membrane is placed, and then the circuit board is inserted. Then the screw is screwed down to the circuit board, so that it is compressed.
- Q: How to choose the plastic film for the salt packing bag?
- Well, there are two parts in your retail package.
