Reason one:
The heating temperature or time is not enough. Please consult about processing instruction with Ethylene Vinyl Acetate EVA Film manufacturer.

Reason two:
Ethylene Vinyl Acetate EVA Film is out of self-life, please use Ethylene Vinyl Acetate EVA Film before expiration. Please confirm with Ethylene Vinyl Acetate EVA Film manufacturer how long the self-life is.

Reason three:
The glass surface is not clean, maybe you use some organic water to wash the glass, make sure the glass surface is clean and dry.

Reason four:
Moisture in the glass surface or Ethylene Vinyl Acetate EVA Film or environment is too much. Please dry it before lamination. Or prolong the low-temperature heating time.

Reason five:
If the lamination takes place in some part of laminated glass, maybe it due to the sweat on the hand of worker, please make sure the worker is wearing gloves.

Any other situation, please feel free to contact us.

Reason 1:

The plainness of the glass is not good. If you making tempered laminated glass, make sure the thickness of Ethylene Vinyl Acetate EVA film is thick enough.

 

 

Reason 2:

The Ethylene Vinyl Acetate EVA film is not melt completely when processing in the laminating vacuum oven, you need to increase the temperature or prolong the heating time to make sure Ethylene Vinyl Acetate EVA Film is melt completely.

 

 

Reason 3:

Stop vacuuming too early. Make sure you keep vacuuming always working in whole procedure of making laminated glass, and only stop the vacuuming after the temperature is lower than 45 degree C.

 

 

Reason 4:

The silicone bag is leaking, so the vacuuming pressure can not reach 0.095MPA.

 

 

Reason 5:

Moisture in the surface of glass, Ethylene Vinyl Acetate EVA Film, decorative interlayers is too much, please dry them before laminating.

 

Reason 6:

Part of laminated glass is suffering too high temperature, and lead to the Ethylene Vinyl Acetate EVA Film decompose to gas. Make sure the heating is well-distributed. And make sure the temperature detector is working well and get the correct temperature.

 

Reason 7:

When edging laminated glass, bubbles appear at the edges. Because edging makes heat, and too much heat causes the bubbles. Please use more water to cool laminated glass when edging, and edging slowly and softly if necessary.

 

Any other situation, please feel free to contact us.

EVA interlayer film is the main row material for producing safety laminated glass

EVA interlayer film is the main row material for producing safety laminated glass, however, the quality of the EVA film is not the only factor for producing standard safety laminated glass, there are many other factors in close relations with the successful production, such as equipment(laminating stove), producing technique, glass and auxiliary materials, environment and weather condition, worker’s operation skill and responsibility.

cnc@cncnext.com / www.cncnext.com / benext77@gmail.com / benext77@hotmail.com / eva@evafilms.com / www.evafilms.com Therefore, in order to produce strengthened glass and safety laminated glass, operator needs to analyse comprehensive factors and master comprehensive producing skill.

The following operation instruction is concerning the actual application of EVA film for safety laminated glass:

 

Storage of EVA film

EVA interlayer film is usually required to be stored in the storehouse that is ventilative, dry and clean. It should avoid direct radiation from light and heat, and should be prevented from rain, high pressure, outside force collision and scratch from hard article. The temperature in storehouse should not be higher than 32℃, and humidity less than 55%. If the stock of EVA film is a large quantity, pallet should be put under the EVA film for ventilation, cooling and anti-moisture. If affected by excessive pressure, heat and moisture, the EVA film will be self-adhesive and its surface will turn to yellow or red in some degree. And if the EVA film is affected All rights reserved by China Ethylene-vinyl acetate EVA Interlayer Film Manufacturer for Safety Architectural Laminated Glass, Smart Glass, Privacy Glass, LED Glass etc.(cnc@cncnext.com / www.cncnext.com / benext77@gmail.com / benext77@hotmail.com) (eva@evafilms.com / www.evafilms.com ) by moisture in too large size, the adhesion between the EVA film and glass will be weaker, which will disable the normal application of EVA film.

It’s forbidden that the EVA film for laminated glass is stored in the same warehouse where combustible stuff and explosives are stored. The remaining EVA film should be re-packed by clear materials, otherwise the static electricity within the EVA [Want to learn more, please contact:=China Ethylene-vinyl acetate EVA Interlayer Film Manufacturer for Safety Architectural Laminated Glass.=China EVA Film for Smart Glass, Privacy Glass, LED Glass etc.=China Solar EVA Film for Solar Panel Encapsulation. =China Switchable Film for Privacy Glass, Smart Glass.= cnc@cncnext.com / www.cncnext.com / benext77@gmail.com / benext77@hotmail.com / eva@evafilms.com / www.evafilms.com ]film will absorb dust that will contaminate EVA film and consequently disable the normal use of EVA film.

The valid storage period of EVA film for laminated glass is within 12 months after the EVA film is produced, so customers have to use old EVA film firstly and meanwhile store new EVA film if inventory turnover is needed. We shall not be responsible for the quality of EVA film that has passed the valid storage period but customer still use it to laminate glass. Or should customers fail to use the EVA film that has passed the valid storage period, we shall not return or exchange the EVA film no matter there’s quality problem within the EVA film or not.
