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.

3).Transportation:there should be no direct sunlight, drench, and violent shaking during the transportation.

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.

 

production of film

Q: Which plastic film is more suitable for making heat shrinkable labels?
Need to blank, QS logo for color requirements, bar code is required for the blank area, height can be adjusted. But not less than GB 1/3.
Q: What kind of material is plastic film in greenhouse?
Plastic film material in greenhouse:Common filmPolyethylene or polyvinyl chloride as raw material, the film thickness of 0.1 mm, colorless transparent. The service life is about half a year.
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: How many kinds of plastic film specifications are there in the greenhouse?
Cold water directly on the seedlings, but also easily lead to rot, these conditions for the growth of crops that are unfavorable. In order to solve this problem, the film factory added one or several surfactants in film formulation, the surface affinity between water and the film is greatly reduced, or eliminated. That can make the greenhouse water vapor formation of water droplets, not attached to the film, but the film along the wall flow to the ground, in order to maintain the transparency of the original film. The plastic film surface active agent called drop film. According to the test, the use of plastic film awning film, than the use of general film greenhouse can improve the temperature of 2 - 4 degrees of UV transmittance of one percent to five with no progress. The film can make the seedling seedling drop, fast growth, good quality, high survival rate, is not easy to rot.
Q: What's the quota for PE membrane isolation layer?
Polyethylene film is a commonly used plastic film, because of its non-toxic, so a lot of food used for making packaging bags. Notice the difference between PVC and polyvinyl chloride (PVC). The simple way is to make the polyethylene film for ignition, and the non flammable is PVC film.A separation layer between a polyethylene film, a barrier layer, an intervening coil, and concrete or other protective layer. It is also considered a separate protective layer.
Q: Plastic film surface corona treatment, the bigger the better?
With our experience and Shun packaging, plastic film on the surface of the corona treatment is not better, if the surface treatment of plastic film spark is too large, will make the surface film breakdown, aging, luster faded, heat sealing performance of adhesion, strength reduction or inner film variation, is not easy to seal.
Q: Masks that layer of white plastic film is used for what?
The role of this layer of plastic film is done in the mask, to prevent the mask itself evaporation of water, so that the skin can better absorb nutrients, even if the time is longer, the mask will not absorb moisture from the skin itself.
Q: How to identify the model of plastic greenhouse film?
Should be 7.5-8 meters, we span 6 meters, with 7.5 meters, just right, both sides can be stuck, 8 meters, a little more.
Q: Why should a plastic film be added to the new cement road?
The new cement road needs a layer of plastic film for better maintenance.
Q: Why use plastic film wrapped legs running, weight loss good?
Wearing a heavy sport suit or body sculpting exercise also temporarily reduces weight, and restores weight as soon as you add water." The best way to lose weight is for a small amount of exercise, a long period of exercise, while focusing on the requirements of a balanced diet. The general principle is that the exercise center rate is 120 times per minute, the duration of exercise lasts more than 45 minutes, the next day or every day, and attention to the diversity of sports events.
