EVA POE Cast Film Extrusion Line

EVA POE Cast Film Extrusion Line has an automatic weighing feeding system to ensure high-precision feeding of various solid and liquid additives and raw materials. The low-temperature extrusion system is fully mixed under the premise of ensuring plasticization to prevent cross-linking of additives.

Description

 Features of GWELL’s EVA/POE cast film production line

 

  1. The whole set of equipment adopts Siemens PLC, closed control, one-level speed increase, and easy operation.
  2. The special screw design of the extruder ensures that the plastic is melted and the extrusion volume is high.
  3. The automatic mold belt thickness gauge can more effectively fine-tune the thickness deviation of the melt on the transverse width of the mold, and the thickness uniformity can be guaranteed to be ±1 wire.
  4. The casting roller adopts the processing method in the inner flow channel to ensure that the temperature is controlled within plus or minus 1 degree, and the roll surface control accuracy is within plus or minus 1 silk, ensuring that the thickness of the cast film is thicker and more accurate.
  5. The Italian Re tension sensor and control system are used to ensure that the tension control is positive and negative 1N.
  6. A full set of servo motors and servo controllers make the equipment run more precisely.
  7. The automatic slitting and winding machine have two functions contact winding and gap winding. Winding has taper tension control, the adjustment range is 5-200N/M.

EVA POE Cast Film

At present, the encapsulation films of double-glass modules mainly include EVA film and POE film. EVA film is an ethylene-vinyl acetate copolymer with a low melting point, good fluidity, high transparency, and a mature lamination process. It is the main packaging material for double glass components. However, due to the low strength of the EVA film, the moisture permeability and water absorption rate are large, and the weather resistance is poor.

 

For double-glass modules, edge sealing is required, but during normal use, water vapor still passes through, causing film fogging, affecting light transmittance, and reducing the power generation of the module. POE is an ethylene-octene copolymer. It is a new type of polyolefin thermoplastic elastomer developed with metallocene as a catalyst with narrow relative molecular weight distribution, narrow comonomer distribution, and structural controllability.

 

There are currently two types of POE films on the market. One is non-crosslinked polyolefin potting materials, which do not contain crosslinking agents. Combined with the use of functional polymers, the heat resistance and adhesion of the materials can meet the requirements of use. The other is a cross-linked polyolefin encapsulant containing a peroxide cross-linking agent or a silane cross-linking agent and a tackifier.

 

EVA film is more and more widely used in various optical products and current components in terms of adhesion, durability, and superior optical properties.

POE has the general characteristics of thermoplastic elastomers, with excellent toughness and good processability, and also has excellent cold resistance, weather resistance, and aging resistance.

 

Production line features

 

1. EVA solar film extrusion line

 

The automatic weighing feeding system ensures high-precision feeding of various solid and liquid additives and raw materials. Low-temperature extrusion system ensures sufficient mixing under the premise of plasticization to prevent cross-linking of additives. Specially designed castings perfectly solve the problems of sticking and peeling.

 

Special online tempering device to eliminate internal stress. The tension control system ensures the smooth conveying of flexible sheets during cooling, pulling, and winding.

2. PVB film extrusion line

 

PVB film is a thermoplastic film made of PVB resin and plasticizer.

 

PVB film extrusion production line is widely used in the interlayer film of architectural glass, automobile, solar photovoltaic glass, bulletproof glass, soundproof glass, etc. It has the characteristics of high safety, sound insulation, UV protection, color or ultra-transparency, etc. It has been used in building wall glass for more than 70 years. It also has optical application value and is also used in solar photovoltaics.

 

There are two kinds of production methods: roll forming and water cooling forming. The thickness of the finished product is 0.38-1.52mm, and the width is 500-3400mm. Transparent, color strip and full-color film are optional.

 

What is EVA hot melt adhesive film?

 

EVA hot melt adhesive film is one of the ingredients in hot melt adhesive film. It is a plastic adhesive. The main material is EVA, which is an ethylene-vinyl acetate copolymer, which is a high molecular polymer. This material has a white matte surface when not in use at room temperature, and becomes transparent after use.

 

EVA hot melt adhesive film has good adhesion to polypropylene, film, sponge and other materials and some components of rubber. EVA hot-melt adhesive film has good elasticity, and it is divided into the paper-lined type and paper-free type. EVA hot-melt adhesive film is a low-melting hot-melt adhesive film with a melting point of only about 70°C. Although the elasticity is good, it is not suitable for the clothing industry. Due to its poor washability, it cannot be applied to some materials that need to be washed.
