As every Laminating
Film Manufacturer realize that laminating film or composite film is usually
produced by affixing geotextile on sides or each sides of film to type
geomembrane. Its type is often included a cloth of a film, two cloth of a film.
Its width may be four to six meters and its weight can be 200 to 1500 grams
each square meter.
What’s extra, it has higher physical and
mechanical properties indexes including tensile, tear, bursting. In addition,
such sort of products is with high strength, fantastic ductility, modulus
deformation, acid and alkali resistance, corrosion resistance, aging
resistance, fantastic waterproof functionality and other very good traits.
That may be why it may meet the
specifications with the many fields including water, municipal, construction,
transportation, subway, tunnel, construction to satisfy the requires of civil
engineering such as anti-seepage, reinforcement, isolation, anti crack,
reinforcement and so on.
As a consequence of the selection of
materials and also the adding of anti aging agent within the production
process, so it may be applied in non normal temperature atmosphere. In
addition, it could be generally applied for anti-seepage therapy in dam and
drainage ditches, and it can also be utilized for anti pollution disposal in
waste field.
Usually speaking, Laminating
Film is created from two distinctive membrane materials. And it's a type of
membrane which can be produced to have a surface active layer (dense layer)
owning separate function and membrane composed of porous layer playing
supporting function.
As for its processing process, firstly,
let’s talk about dry compound approach. The process would be to make adhesive
coat on the surface of the substrate by utilizing compound machine and make
heating rolling attach to other films to finish composite
Secondly, let’s see the wet compounding
strategy. We should really make water soluble adhesive (gelatin, starch), water
dispersible adhesive (vinyl acetate latex) coat on the substrate surface and
finish composite with other materials under the wet condition, and after that
dry them by utilizing the rolling.
Thirdly, speaking of extrusion strategy, it
truly is by far the most normally used approach in composite processing. Film
Cutting Machine might be employed in this system. That is certainly for
sure.
