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 are the factor 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:Will plastic films refract light?
Agricultural film is made of ordinary plastic, commonly known as PE film, in high temperature (100 degrees or more), slightly poisonous, good point inside the PE film, added anti ultraviolet material, sunscreen good point (use time will be longer).
Q:Is it good to use paper bags or plastic film bags?
With asbestos mesh (general dish pack more use of this media) direct contact with the disk, the relative effect is better
Q:Is the film capacitor CBB capacitor?
The film capacitor is not necessarily a CBB capacitor, but the CBB capacitor must be a film capacitor. Because the film capacitor contains other capacitors such as CL21
Q:What are the plastic film types and scope of use?
The biaxially oriented polypropylene film is prepared by the co extrusion of polypropylene particles and then by stretching in two directions. Due to stretching of molecular orientation, physical stability, so this kind of film mechanical strength, good air tightness of transparency and gloss, high tenacity, wear-resisting, is currently the most widely used printing film, generally use the thickness of 20 ~ 40 m, the most widely used is 20 m. The main drawback is the biaxially oriented polypropylene film heat sealing is poor, so generally used as an outer film composite film, such as polyethylene film and composite moisture resistance, transparency, strength, stiffness and printability were ideal, suitable for holding dry food. Because the surface of biaxially oriented polypropylene film for nonpolar, high crystallinity and low surface free energy, therefore, the poor performance of printing, ink and adhesive adhesion, surface treatment and compound before printing.
Q:Plastic film sealing machine (Dorch) repair
You, I have not seen this model, I do not know is semi-automatic film sealing machine, but also pedal, or hand press?. Pass the picture and see his structure.
Q:How can the weathering of the plastic film on the surface of FRP be removed?
Corona treatment. It is commonly known as electrical discharge treatment, which is the most common treatment for plastic film production, printing and compounding. The process of EDM processing is that processor release high frequency and high power, produce small dense purple spark to the impact surface of plastic film, chemical bond breaking molecules on the surface of plastic film and degradation, increased the surface roughness. In addition, a large amount of ozone is generated at the same time of discharging, and the surface of the film is oxidized to produce a strong polar group, such as carbonyl group and peroxide, so that the surface of the plastic film is roughened, and the surface tension of the film is enhanced.
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:The material, characteristics and uses of various plastic films
HDPE-LDPE-LLDPE films produced by this type of product; used for food packaging, film preservation and the like.
Q:What solvent can be used to remove the plastic film glued to the glass?
The range of application is suitable for diluting all kinds of nitro wood paint.Product features:1, low odor, no residue2, strong solubility, good matching3, moderate drying speed, easy construction, preferably esters, alcohols, aromatic hydrocarbons and other organic solvents, low odor, good solubility, good construction performance, applicable to dilute all kinds of nitro wood paint.
