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:Why should a plastic film be added to the new cement road?
- The maintenance of concrete, according to the thermal calculation, concrete internal and surface temperature is less than 25 degrees, concrete pouring time after surface covered with a layer of plastic film insulation, timely prevent the conservation of water caused by excessive temperature difference between inside and outside the concrete temperature crack.
- 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: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.
- Q:Why would you wrap plastic film in a tree?
- Wrapped plastic is to keep moisture, in order to prevent evaporation of water and die plants, and afraid of the wound fungal infection.
- Q:Can the concrete surface be covered with plastic film in winter construction?
- The hardening process of concrete is the chemical reaction of water. Concrete is called concrete when hardened. Concrete releases heat in chemical reactions, and heat accelerates the evaporation of water in concrete. Therefore, concrete pouring must ensure that the moisture content of concrete mixture can meet the needs of this chemical reaction.
- Q:How to identify the model of plastic greenhouse film?
- Thickness of what can be compared with your current use. General color slants blue, thickness is high, the price is expensive. Poor transparency, white, thin, low prices
- Q:Why should farmers cover plastic film when sowing in the spring?
- Negative effects of plastic mulchPlastic film mulching has both negative effects and positive effects such as: plastic film mulching has the role of water retention, but hindered the outside precipitation into the ridge body parts, if does not take the corresponding ridge or other measures may lead to crop water deficit occurred in the long-term flourishing, affect the normal growth; when continuous rainfall when it is easy to cause serious water damage, the soil permeability is bad, water evaporation is blocked, also affect the growth of crops. Therefore, combined with the actual production and local, making mulch production technology feasible, make full use of the film role, take corresponding measures of success is covered with plastic film base.
- Q:Are planted steel structure plastic film shed structures?
- The planted steel structure plastic film greenhouse structure does not belong to the category of structures, and the main reasons are as follows:Structures generally refer to places where people are not directly involved in production and living activities. Such as water towers, chimneys, Zhanqiao, dams, reservoirs and so on. Normally, so-called structures are artificial structures that do not have, do not contain, or do not provide human habitation, such as towers, ponds, filters, clarifier, digesters, etc.. An artificial building that has, contains, or provides human habitation, known as a building. The name of the structure is much more in the textbook of water supply and drainage. It should be noted that this definition is not absolute. In water conservancy and hydropower projects, all structures on rivers and channels are called buildings, such as hydraulic structures.
- Q:How to quickly remove the plastic film on the floor tiles?
- 1, ceramic tile daily cleaning can choose detergent, soap and other cleaning. 2, with soap, add a little ammonia and turpentine mixture, cleaning tiles can make tile more luster. 3, polished brick should be regularly waxing, the time interval is 2-3 months is appropriate. 4, such as brick surface scratches, can be applied in the scratch of toothpaste, wipe with a dry cloth can be repaired. 5, brick and brick crevice can be used regularly decontamination paste to dirt, and then brush a layer of waterproof agent in the gap, can prevent mold growth. 6, tea, coffee, beer, ice cream, grease and other pollutants using sodium hydroxide or potassium bicarbonate solution. 7, ink, cement and other pollutants use hydrochloric acid, nitric acid and other dilute solution. 8, paint, paint and other pollutants use special cleaning agent.
- Q:Is it possible to lay a plastic film between the roof slab and concrete for waterproofing purposes?
- The seam of the prefabricated plate is very easy to crack. The plastic film is not good enough and is easy to pierce. Once it rains, it basically can't get waterproof effect;
