The new high-strength pillarless greenhouse frame has significant advantages over existing steel, cement, and bamboo-type greenhouse frames:
First, high strength and good toughness.
The skeleton of greenhouse adopts nano-activated innovative composite materials, which significantly improves the compactness, strength and toughness of the skeleton; and, due to the use of superimposed reinforcement and double-strengthening technology during the production process, the skeleton has superior strength and toughness. According to the test results of the National Building Decoration Materials Quality Supervision and Inspection Center, the single-frame skeleton has a flexural strength of 3,866 N, equivalent to a strength of 400 kg, which is equivalent to the weight of 6 or more adults. At the same time, the ribs with strong flexibility are integrated into the skeleton during production to make it more resilient and resistant to impact and breakage.
Second, extremely strong water resistance, corrosion resistance, flame retardant.
The inspection results of the National Building Decoration Materials Quality Supervision and Inspection Center show that several sections of the skeleton of the greenhouse are intercepted and immersed for 200 hours in ordinary water, aqueous solution of strong acid of sulfuric acid, and aqueous solution of strong alkali of sodium hydroxide. After removal, no fragments are observed. And swelling phenomenon. Then, using a 1000g steel ball to impact the skeleton from a height of 3 meters, no cracking or chipping phenomenon was observed. Because the skeleton uses non-combustible materials, it has a strong ability to resist water and fire damage.
Third, extremely resistant to freezing and thawing.
The inspection results of the National Building Decoration Materials Quality Supervision and Inspection Center show that the skeleton was subjected to 20 freeze-thaw cycle destructive tests at -25 degrees Celsius (nearly 20 times, equivalent to 20 years), and no crack or block was found on the skeleton. And stratification. In order to avoid the adverse effects of freeze-thaw caused by the difference between the normal temperature in other regions and the normal winter weather conditions in the northeast and northwest regions of China.
Fourth, the humidity is stable and the service life is greatly increased.
During the production, the moisture-proof surface fabric is also covered on the outside of the outermost layer of the overlay, which effectively ensures that the internal moisture of the skeleton is not lost, and moderate humidity is maintained, thereby increasing its service life. It has been determined that the shelf life can be as long as 15-20 years.
Fifth, there is no pillar, large space, lighting and high land utilization.
High-strength greenhouse frame according to user requirements, length, span, arc, height, color can be arbitrarily adjusted, the shape can be arbitrarily curved, without pillars in the greenhouse, there is no sunlight dead corner in the greenhouse, land utilization, lighting performance has been unprecedentedly improved, Basically mechanized operations can be achieved. The structural design model is also a revolution in the history of greenhouse development.
Sixth, light and inexpensive, neat and beautiful appearance, does not hurt the film.
The frame of high-strength greenhouses is light weight and only 1/3 of the weight of the cement skeleton. The cost is low, the cost per mu is only about 3,000 yuan, and the market is more profitable. The exterior of the skeleton is neat and beautiful, the contact surface of the film is smooth without protrusions, the film of the film is not damaged, and the service life of the film is effectively extended.
