Product Description:


Brief description ‍of PVB Interlayer Film:


PVB interlayer  is a macromolecule material molded by polyviny, butyral resin that is plasticized and extruded by plasticity. Our PVB film with excellent light transparency, heat and cold resistance, elasticity, is well-sticking to inorganic glass and the making of laminated safety glass. Usual thickness specification is between 0.2 mm - 2 mm.


Usage of PVB Film:


PVB interlayer is mainly used in making laminated safety glass. Laminated glass is a special glass which is inserted with PVB film between two layers of common glass, which under high heating temperature and pressure, binds to create a single construction. Because of PVB laminated glass with the function of safety, heat preservation, noise proof, and ultraviolet resistance, etc, it is widely used in areas such as high-rise building and auto. PVB film with special formula is also used in airplane, space flight ware, military instrument, solar battery, solar energy acceptor and so on.



PVB Film Features:



The PVB interlayer withstands penetration from impact. Even if the glass cracks, it will only have web-shaped similar fine cracks, and splinters will adhere to the interlayer and not scatter. In such case. it still can be used until it is replaced.

2,Burglary Proof

Since the laminated glass with QIXUE PVB interlayer is very shock resistant, even if a burglar cracks the glass, the laminated glass can still keep its structure integrity because of the middle-layer adherence tenacity. As such, the laminated glass has much strength to resist shock. It also helps reduce outside visibility

3, Structure Integrality

Performance of laminated glass is the Same as single piece glass under the normal load. however once the glass broke up. laminated glass can keep its structure integrality. little shattered glass dropping down.

4, Sound Control

PVB interlayer in laminated safety glass has a resisting effect on sound waves. PVB laminated glass can effectively prevent the spread of noise especially those located in airports, railway stations, and busy streets.

5, Anti-Ultraviolet

PVB interlayer can filter 99 % of the ultraviolet light thereby helping to avoid direct sunlight and delaying the aging and fading of interior decoration to prolong its service life

6, Energy conservation

Laminated safety glass with QIXUE PVB interlayer can provide an outstanding heat-resisting performance and help save energy conscription. When the laminated glass adopts dark PVB interlayer with low-light transmittance, the same thickness has a stronger thermal resistance effect.


Packing of PVB Film:


Every layer Of PVB film roll is separated by PE film and vacuumed by aluminum foil and put into wooden cases. The finished quality-control approved product is enclosed with conformed certification and packing list.



Guarantee period of PVB Film:


Well-stored and under normal temperatU re, the product has a quality guarantee Of 2 year.

Q:Are planted steel structure plastic film shed structures?
The planted steel structure plastic film greenhouse structure does not belong to the category of structures, and the main reasons are as follows:Structures generally refer to places where people are not directly involved in production and living activities. Such as water towers, chimneys, Zhanqiao, dams, reservoirs and so on. Normally, so-called structures are artificial structures that do not have, do not contain, or do not provide human habitation, such as towers, ponds, filters, clarifier, digesters, etc.. An artificial building that has, contains, or provides human habitation, known as a building. The name of the structure is much more in the textbook of water supply and drainage. It should be noted that this definition is not absolute. In water conservancy and hydropower projects, all structures on rivers and channels are called buildings, such as hydraulic structures.
Q:Concrete pouring process can use plastic film capping, 12 hours after watering maintenance?
Large volume concrete will be covered and maintained within 12 hours after pouring. At last, thermal calculation should be carried out carefully, and temperature measurement work should be strengthened. Thermal insulation and maintenance shall be adopted to reduce the internal and external temperature difference of mass concrete. It is also important to strengthen the maintenance of concrete. In the construction of mass concrete, it should be covered with pouring edge, and be maintained and maintained after 5 ~ 7d.
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 are the factor affecting the puncture strength of plastic film?
The general physical and plastic film thickness, tension, the heat and other factors, but also has a relationship with the processing of materials used in production, if not assured the puncture strength of plastic film is not qualified, can choose the market force commonly used CCY-02 puncture tester to check.
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:Do you have adhesive for plastic film?
1, do not wear knitted gloves, KD-800 series of special rubber gloves are woven material absorption will rapidly produce high heat polymerization reaction, will burn your hand, so please remember, don't wear gloves knitting.2, if the eyes accidentally come into contact with hard cured glue will hurt the eye, do not use hand rub, and immediately rinse with plenty of water or warm towel and heat, the eyelids sweating apart, do not force open, serious and send to hospital for emergency treatment; skin contact with warm soapy water, soaked with acetone KD series solution of glue removal.3, the KD series of flash drying steam is irritating. Please use the ventilation system in the workplace when used in large quantities.4, when there is a lot of leakage, you can use water to cure and then scrape.
Q:FFS plastic film bags are injection types?
FFS plastic film bags are not injection molding, blow molding.
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.
Q:Which plastic film is more suitable for making heat shrinkable labels?
The shrinkage ratio of the PVC longitudinal film is inconsistent. Not single, it fits all bottles.
Q:What kind of equipment will be used for plastic film production?
First is the 30 type and 40 type blowing machine each, and the electric spark impact machine two. 6 color gravure press about 200 thousand, bag making machine.
