As each and every Laminating
Film Manufacturer know that laminating film or composite film might be
produced by affixing geotextile on sides or both sides of film to type geomembrane.
Its type is often incorporated a cloth of a film, two cloth of a film. Its
width could be four to six meters and its weight is often 200 to 1500 grams
every single square meter.
What’s extra, it has high physical and
mechanical properties indexes such as tensile, tear, bursting. Additionally,
such sort of merchandise is with high strength, excellent ductility, modulus
deformation, acid and alkali resistance, corrosion resistance, aging
resistance, fantastic waterproof performance and other excellent traits.
That's why it might meet the specifications
from the quite a few fields for example water, municipal, construction,
transportation, subway, tunnel, construction to satisfy the needs of civil
engineering like anti-seepage, reinforcement, isolation, anti crack,
reinforcement and so on.
On account of the choice of materials plus
the adding of anti aging agent in the production process, so it could be
utilized in non typical temperature environment. Moreover, it could be
frequently made use of for anti-seepage therapy in dam and drainage ditches,
and it might also be applied for anti pollution disposal in waste field.
Typically speaking, Laminating
Film is made from two distinctive membrane materials. And it is a type of
membrane which is produced to have a surface active layer (dense layer) owning
separate function and membrane composed of porous layer playing supporting
part.
As for its processing approach, firstly,
let’s speak about dry compound technique. The strategy is always to make
adhesive coat around the surface from the substrate by using compound machine
and make heating rolling attach to other films to finish composite
Secondly, let’s see the wet compounding
approach. We must make water soluble adhesive (gelatin, starch), water
dispersible adhesive (vinyl acetate latex) coat on the substrate surface and
finish composite with other components below the wet situation, then dry them
by using the rolling.
Thirdly, speaking of extrusion process, it
is actually the most commonly used system in composite processing. Film
Cutting Machine could be employed within this technique. That is for certain.
