- Q:Why should a plastic film be covered after civil construction?What's the point? Do you have any requirements for plastic film?
- Is used for curing concrete. Because cement solidification requires proper moisture, moisture to react to the concrete hardness increasing. Covered with plastic film to prevent water evaporation. If excessive moisture evaporation, will affect the curing of concrete, can produce dry, peeling and other phenomena, affecting the strength of concrete.
- Q:Why are more transparent plastic films used in flower sheds instead of glass?
- Glass greenhouse installation and late maintenance is not convenient. The installation and maintenance of glass greenhouse is very inconvenient, and the economic benefits can not be effectively guaranteed.Plastic greenhouse installation is simple, demolition is also relatively simple. As the light intensity of plastic greenhouse is relatively weak, air humidity will also be improved, and its use is mostly used in seasonal cultivation facilities and fully utilized.
- 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:Installation of air-conditioning machine inside the plastic film did not take off, the impact on the air-conditioning?
- The external machine is higher than the internal machine, if it is a new machine, the contradiction shows little, once the time is long, there will be a problem.The biggest problem is the oil return system, compressor in high evaporator in the lower, especially in the refrigeration temperature, oil viscosity, oil is not easy to return to the compressor, the compressor oil shortage, especially in the course of time, easy to damage.
- Q:How is the blow up ratio of a plastic film calculated? What's its formula?
- Blow up ratio is blown film film diameter and blowing up after the film bubble diameter ratio, there is a simple algorithm, the film finished product multiplied by 2 divided by 3.14, that is, the film bubble diameter. Membrane diameter is certain
- Q:Why use plastic film wrapped legs running, weight loss good?
- After drinking and eating, the cells returned to their original form. This results in increased electrolyte loss, fatigue and poor health. Wrap the body with plastic wrap for a long time, so that the skin can not dissipate heat and sweat accumulation in the local, easy to cause eczema, folliculitis and other skin diseases. In addition, the preservative film itself is a chemical, but also prone to skin allergies, causing other potential hazards to the body."
- Q:What is a water-soluble plastic packing film?
- Water soluble plastic packaging film as a new green packaging materials. The main raw material is low alcoholysis of polyvinyl alcohol film, water solubility and degradability by polyvinyl alcohol, adding various additives, such as surfactants, plasticizers, anti adhesive agent. Water soluble film products belong to green packaging materials and in Europe, Japan and other countries have been recognized by the national environmental protection department. At present, the main domestic and foreign biological oxygen demand (BOD) and chemical oxygen demand (COD) as an environmental indicator. The Japanese authorities determination of PVA biological oxygen demand (BOD) is much smaller than the starch, the United States Air Products to PVA biological products Airvol, after 5 days degradation can be measured the amount of BOD is lower than the initial volume of BOD 1%. through the biological experiment proved that polyvinyl alcohol are non-toxic, does not prevent the growth of microorganisms, has no influence on wastewater treatment and environmental health The microbial decomposition tests also showed that the PVA was almost completely decomposed, resulting in a very low COD
- Q:What is the corona treatment of plastic film?
- Process circuit form:The first form is in the production line of the film, which is commonly referred to as heat film treatment, which is the most common form of treatment. Because the polymer molecules have not yet completed the crystallization of the processing, and therefore the processing effect is strong, but generally only applies to immediately re processing (such as printing, coating or composite) film processing. The processing device is arranged behind the film cooling setting section and prior to the coiling device.The second form is on the film reprocessing line, which is commonly referred to as cold film treatment, and the quality of this process is also related to the experience of the film. If the film deposited after a long storage time, a large number of precipitated additives attached to the surface of the film, the quality of treatment will become worse. In this way, it should be noted whether the spark will cause the possibility of fire on the solvent used. The processing device is provided prior to the printing (or coating or compounding) device.The third form is the combination of the above two forms, which is first processed on the film production line, and then processed second times on the re processing line of the film. It is suitable for the first time to deal with poor quality, or after the first treatment, the storage time has been long, and the treatment effect has been dissipated by many films.
- Q:What plastic films can be made into plastic bags?
- Nylon thin films, PET films, BOPP films, PE films, CPP films, heat sealable BOPP films can be made into composite bags.Among them, PE films, CPP films, and heat sealable BOPP films, these three films should be made as inner layers because they are beneficial to heat sealing.
- Q:When will the plastic film be opened when the vegetables are sprouting?
- One is to take mulch after sowing; two is the plant after the emergence of the seedlings at the top of the window film, let out seedling growth;
