Product Description:

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.

Q:What material is the film on the waterproof roll? What's your name?
The construction of other structural layers on the waterproof layer may puncture the damaged waterproof layer, and proper protection is necessary, and the isolating layer can also play a protective role at the same time.
Q:How often will the plastic film in the greenhouse be replaced?
In actual production, once a year. Although now the film is very durable, but light, fog, dripping the new film or better.
Q:What kind of plastic film is a little sticky and can be affixed to the label perfectly? What is it like a sticker?
Fresh keeping film。Film is a kind of plastic packaging products, usually with ethylene as masterbatch through polymerization is made, mainly used for microwave heating of food, food preservation, refrigerator fresh and cooked food packaging etc., are widely used in the field of food packaging, family life supermarket stores, hotels and industrial production. According to the materials used and different plasticizers, the plastic wrap is divided into a variety of types, suitable for different occasions. Cling film has been favored by people for its convenience, economy and beauty. However, due to the addition of plasticizers in the process of production, the effect of plastic wrap on human health has also attracted people's attention.
Q:Why use plastic film wrapped legs running, weight loss good?
After drinking and eating, the cells returned to their original form. This results in increased electrolyte loss, fatigue and poor health. Wrap the body with plastic wrap for a long time, so that the skin can not dissipate heat and sweat accumulation in the local, easy to cause eczema, folliculitis and other skin diseases. In addition, the preservative film itself is a chemical, but also prone to skin allergies, causing other potential hazards to the body."
Q:Can electrostatic generator adsorb plastic film?
The electrostatic generator is safe, controllable and reliable, producing static electricity and adsorbing the material. Fixation and closure.The electrostatic generator is provided with an electrostatic generating head and an electrostatic generating rod, and is used for producing a plurality of assembly lines with static electricity.Using electrostatic generators, it is better to select the more experienced companies, which should have years of experience and advanced equipment.
Q:Should the film on both sides and back of SIEMENS refrigerator be torn off?
In the past, the condenser of the refrigerator was installed in the back of the refrigerator. It can be seen that the condenser directly sends out the heat. Now the process is improved for beauty and cleanliness. The refrigerator manufacturer installs the condenser inside the iron sheet.
Q:How many kinds of plastic film specifications are there in the greenhouse?
PVC and PVC film, polyethylene plastic film and polyethylene film, is currently the largest amount of agricultural production in two kinds of plastic film. The PVC film, because of good comprehensive performance, is China's agricultural production on the popularization and application of the longest time, the maximum number of a polyethylene film is applied in recent years. The varieties, because its superior performance, dosage is increasing greatly,
Q:Can it be covered with plastic film after pouring concrete outside zero?
Yes, it does matter. Norms have regulations, 5 degrees above zero temperature, to take winter construction measures. Zero degrees Celsius, concrete pouring is not easy to operate, quality is difficult to guarantee, mixing water is ice water mixture, concrete will be slightly frozen.
Q:What's the packing material for yogurt? Plastic bags, then what plastic film, and can not use carton packaging?
Yogurt packaging materials are film, paper, multilayer composite materials, plastic bags are mainly PE, PP, PVC, etc., can be packed in cartons.
Q:A concrete cover film, under what circumstances to cover, what does not cover
The thin film is a thin, soft transparent sheet. Made of plastics, adhesives, rubber, or other materials. A scientific interpretation of a polyester film is a 2 dimensional material formed by atoms, molecules, or ions deposited on the surface of a substrate. Example: optical film, composite film, superconducting film, polyester film, nylon film, plastic film and so on. Films are widely used in electronic, electrical, mechanical, printing and other industries.
