Introduction
Film greenhouse produced by China tunnel film greenhouse supplier is also known as the PLUS upgraded version of the greenhouse, the main composition of the main structure is mainly made of hot-dip galvanized lightweight steel structure for vegetables, flowers, fruits and other crops that require special greenhouse conditions.
Advantages
- Durable: Scientific process, simple processing technology, easy to understand operation, no need for equipment, handmade, with a wide range of raw materials. The framework of the thin film greenhouse produced by China tunnel film greenhouse supplier is lightweight and sturdy, making disassembly, installation, and transportation very convenient. Compression and bending resistance, high strength, good thermal insulation performance, and strong wind resistance. Non rusting, not afraid of water, corrosion-resistant, moisture-resistant, no deformation or fracture from high temperature of 100 ℃ to low temperature of -60 ℃.
- Multi function: film greenhouse produced by China tunnel film greenhouse supplier can be used in seedling greenhouse, Vegetable farming in cold winter, shading, waterproof and rainproof in summer, rice seeding, breeding and protection of livestock and poultry in winter, cultivation of flowers, fruit trees, Chinese herbal medicine, etc., construction of Yurt, milk stations, resorts, and production of cold sheds, mushroom sheds, breeding sheds, construction sheds, vehicle storage sheds, warehouses, small workshops Activity rooms and hundreds of other products.
- While produced by China tunnel film greenhouse supplier, the use of thin film greenhouse skeleton technology can produce various types of greenhouse skeleton products, including arc, rectangular, elliptical, irregular, plastic plated, solid, hollow, etc. The length, curvature, height, span, and thickness can be adjusted at will.
- Reliable quality: The framework technology of thin film greenhouse produced by China tunnel film greenhouse supplier is reliable and has been promoted nationwide. The product is as hard as stone, as smooth as a mirror, with low heat absorption and conductivity. It does not bake or burn greenhouse films, is resistant to aging, non-toxic, odorless, and pollution-free. It is installed neatly and does not need to be replaced every year. Its service life can reach 10-15 years or more. It is an ideal substitute for greenhouse brackets (skeletons) made of materials such as bamboo, concrete, steel pipes, steel bars, aluminum alloy profiles, and plastic steel in the current market.
- Low cost: While produced by China tunnel film greenhouse supplier the film greenhouse bracket is 1/8 of the cost of steel frame and 1/3 of the cost of concrete. The cost is less than the main material, and the quality is better than the steel frame.
Effectivenesses
Heat preservation
The insulation function of thin films refers to the heat absorbed by all objects, including crops, during the day in the greenhouse during autumn and winter, and the heat generated by the temperature difference between inside and outside the room at night. While produced by China tunnel film greenhouse supplier, when the heat in the form of infrared rays flows from high to low, it is blocked back by the greenhouse film added with an infrared line barrier when it radiates and scatters outside the greenhouse, allowing it to continue to be maintained inside the greenhouse and minimizing heat loss, Slow down the decrease in indoor temperature. This is an active regulation based on the principle of blocking infrared radiation, which can effectively avoid sudden temperature changes in the greenhouse, thereby avoiding crop frost damage and growth inhibition.
Cooling
The cooling effect of greenhouse films is limited by the addition of a certain proportion of whitening agents while produced by China tunnel film greenhouse supplier. The application scope is relatively special. To ensure the normal photosynthesis of crops, it is usually installed on the facade and special orientation of greenhouses, suitable for strong radiation climates and crop deviation caused by strong summer sun exposure. This type of film cannot be equated with a shading net. The cooling degree of the film is very limited, and it can only partially and periodically alleviate strong sunlight, and cannot completely replace the role of the shading net.
Moisture controlling
The drip and defogging functions of greenhouse film produced by China tunnel film greenhouse supplier can prevent the formation of fog, while converging condensed water droplets attached to the inner surface of the membrane into a large water film and forming an orderly flow of water along the top arc direction, reducing severe moisture caused by disorderly water droplets scattered inside the greenhouse, thereby reducing the occurrence and spread of pests and diseases, and also increasing the transparency of the membrane.
Adjusting lighting
Too much direct light can bring more shadows and cause uneven crop growth, while appropriate scattered light makes the light distribution in the greenhouse film produced byChina tunnel film greenhouse supplier, which is particularly beneficial for rattan crops. At the same time, it greatly alleviates the light radiation during strong light seasons, and the stomatal opening and closing of crop leaves during respiration are better. In addition, in areas with strong solar radiation, scattered light can also reduce the intensity of light, soften the lighting inside the greenhouse, and provide some protection for crops. A scattering functional film that appears less transparent does not necessarily mean low light transmittance. The total transmittance of incident light is very little affected by the form of light distribution – scattering or direct light, and can be ignored.
