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.

- Q: What PE plastic film?
- PE film.There are many kinds, such as HDPE.MDPE.LDPE.LLDPE. Etc..Generally speaking, LDPE and LLDPE are used more in printing. Low density polyethylene
- Q: Should the surface of the plastic film be removed when the activated carbon is used?
- If it is a small bag of activated carbon, there is no need to remove the outside bag, directly scattered every small bag at home.
- Q: How many kinds of plastic film specifications are there in the greenhouse?
- In order to adapt to the various aspects of agricultural production, agricultural plastic film has a variety of different varieties and specifications. According to the use of plastic raw materials, divided into PVC plastic film and polyethylene plastic film;. According to a method of manufacturing a plastic film, divided into pressure Ting film, blown film; according to some special properties of plastic film there were no film, seedling, drop film, film, thin film, colored cover wide film, packaging film etc. according to the different width and thickness of the plastic film, there are a variety of different specifications.
- Q: What's the quota for PE membrane isolation layer?
- Polyethylene film is a commonly used plastic film, because of its non-toxic, so a lot of food used for making packaging bags. Notice the difference between PVC and polyvinyl chloride (PVC). The simple way is to make the polyethylene film for ignition, and the non flammable is PVC film.A separation layer between a polyethylene film, a barrier layer, an intervening coil, and concrete or other protective layer. It is also considered a separate protective layer.
- Q: New car tires have a transparent plastic film, will not be a problem car, new tires, or the car is the same when you leave the factory?
- If 4 are available, it's not a problem, but I've never seen a plastic film on a new tyre
- Q: What are the composite ways of plastic film?
- The coextrusion process is the process of extruding a single resin or a variety of resins and extruding them through several molds to form a film (blown into film or cast into film). This composite does not use adhesives, so the composite film will have no residual solvents.
- Q: How to remove the plastic film on the steel door?
- General door film, the best in 40 days after installation, immediately tore off the protective film, otherwise, when long, is stuck in it, not clear. Because there is paint on the door, it is not recommended to use gasoline, toluene and other solvents to dilute, otherwise, the door will also remove the paint.
- 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: How many days can the concrete be taken away from the concrete?
- Plastic film maintenance refers to the plastic film Wei cover to separate the concrete and air, the water is not evaporated, cement concrete in the water to complete hydration, has reached condensation, hardening. This method can be directly covered in plastic draft on the surface of concrete, or plastic sprayed on the surface of emulsion concrete, until the emulsion of volatile, with a layer of plastic film on the surface of the concrete, in order to make the concrete component isolated from the air to the concrete moisture evaporation and no hydration complete the function. Spray plastic film maintenance is 28d concrete strength low around 8%, because the film is thin, can not be completely separated, frozen adiabatic effect, so in the summer of this method is to add sunscreen facilities (not less than 24h), or will lead to concrete cracks producing filamentous. Generally speaking, the cost of natural maintenance is low, the effect is good, but the maintenance period is long. In order to shorten the curing period, increase the turnover rate of the template and the utilization rate of the site, it is suitable for heating maintenance in general production of prefabricated components.
- Q: Can plastic film protect against ultraviolet rays?
- The transparent film itself UV blocking effect is not good, the general need to add other ingredients, such as color masterbatch, metal particles etc..
