Description of EVA Film

 

EVA film is based on EVA resin which basis to ethylene and vinyl acetate copolymer resin, by adding a variety of modified additives, through melt extrusion made of the rmosetting hot melt film. Not be sticky in normal temperature, easy to operation. Produced by thermal lamination with the bonding enhanced crosslinking chemical reactions, making silicon wafers, glass, TPT multilayer material consisting of one firm bond as the product of solar panels, in actual outdoor applications up to 25 years life. A large number of applications at home and abroad well-proven solar panels, EVA film is the optimum cost performance, it is difficult to alternative packaging materials for solar cells.

pict of film

Q: Is there any material in the strong film made of plastic material which is resistant to high temperature, piercing, and has high tensile properties and can not tear off the film?
The LLDE film may be dedicated to heavy packaging, pierce resistant, tear resistance, tensile, and high temperature resistance depends on what degree requirements, the general level is possible, to have a high temperature resistant performance of plastic is not practical.
Q: Why should farmers cover plastic film when sowing in the spring?
Reduce the damage of weeds and aphidsMulch can inhibit weed growth. In general, the coverage of weeds covered by mulch is reduced by more than 1/3. If combined with herbicides, the effect of weed control is more obvious. After spraying herbicide, plastic film and film covering weeds can reduce 89.4~94.8%. The film has a reflective effect, and can partly avoid aphids, inhibit the propagation of aphids, and reduce the spread of hazards and diseases.
Q: A concrete cover film, under what circumstances to cover, what does not cover
The hydration heat of the cement requires only twenty percent of the actual water, and the rest will evaporateAll water evaporates to form a contraction
Q: The plastic film on the mattress doesn't tear off. Is it good for the body to sleep?
The plastic film on the mattress doesn't tear off and the sleeping doesn't affect the body, because it also cushions the bed and makes the bed list.
Q: What are the composite ways of plastic film?
Wet laminating is the application of an adhesive (glue) to a film (foil), pressed together with a compound, and then dried by a drying oven. It is usually a composite method used in the composite processing of metal foil or plastic film and paper, and the water-soluble adhesive is used in the composite process.
Q: How often will the plastic film in the greenhouse be replaced?
In actual production, once a year. Although now the film is very durable, but light, fog, dripping the new film or better.
Q: What film plastic is transparent and good for aging?
Performance comparisonAlthough the thermal conductivity of FRP is lower than that of PC, the FRP lighting board is usually a single layer, and the heat conductivity is higher than that of the PC solar panel (multilayer structure), that is to say, the indoor temperature under the FRP lighting board is higher if the sun shines in summer.
Q: What is a water-soluble plastic packing film?
On the degradation mechanism of polyvinyl alcohol, has water and biological degradation characteristics of two kinds of first, soluble in water to form a gel into the soil, increase soil mass viscosity and permeability and water retention, especially suitable for sand transformation. In the soil of PVA by soil bacteria isolated from a single cell (Pseudomonas - strain) decomposition. At least two kinds of system composed of commensal bacteria can degrade polyvinyl alcohol: an active bacteria bacteria is polyvinyl alcohol, the other one is to produce PVA active bacteria substances required for bacteria. The oxidation of secondary alcohols catalyzed by polyvinyl alcohol, then enzymatic hydrolysis by cutting the main chain of PVA, further oxidation degradation, eventually for CO2 and H2O. degradation
Q: What are the differences between geotextiles and geomembrane?
Geotextiles, also known as geotextiles, are synthetic geosynthetics made from synthetic fibers by means of needle or weave. The finished product is in a cloth shape with a width of 4-6 meters and a length of 50-100 meters. Geotextiles are divided into woven geotextile and nonwoven geotextile. Geotextile has excellent filtration, drainage, isolation, reinforcement, seepage prevention and protection. It has light weight, high tensile strength, good permeability, high temperature resistance, cold resistance, aging resistance and corrosion resistance.
Q: Plastic film surface corona treatment, the bigger the better?
With our experience and Shun packaging, plastic film on the surface of the corona treatment is not better, if the surface treatment of plastic film spark is too large, will make the surface film breakdown, aging, luster faded, heat sealing performance of adhesion, strength reduction or inner film variation, is not easy to seal.
PROTECT, is the professional manufacture Enterprise with the largest investment scope, the most comprehensive product Specifications, strong production capacity and the highest sales volume, mainly produce special materials PVB and EVA film for bullet-proof glass, windscreen of the automotive, architectural safety glass as well as solar cell panel.
