Folding light transmission

Greenhouse is a light building, and thus light transmission rate is a basic indicator of greenhouse light transmission performance. Transmittance refers to the amount of light entering the greenhouse and the percentage of outdoor light. The light transmittance of the greenhouse is affected by the light transmission performance of the greenhouse light transmission and the shadow rate of the greenhouse skeleton, and the light transmittance of the greenhouse is also changing with the different solar radiation angles in different seasons. Greenhouse light transmittance has become a direct influence on crop growth and seed selection. In general, even the plastic greenhouse in 50% to 60%, glass greenhouse light transmission rate of 60% to 70%, solar greenhouse can reach more than 70%.

Folding insulation

Heating energy consumption is the main obstacle to the winter run of the greenhouse. Improve the greenhouse insulation performance, reduce energy consumption, is to improve greenhouse production efficiency of the most direct means. Greenhouse insulation ratio is a measure of greenhouse insulation performance of a basic indicator. Greenhouse insulation ratio refers to the smaller thermal resistance of the greenhouse light transmission material coverage and thermal resistance of the greenhouse area of the larger coverage area of the ratio of the same area. The greater the insulation ratio, the better the greenhouse insulation performance.

Greenhouse greenhouse insulation performance is very good, heating energy consumption is the main obstacle to the winter run of the greenhouse, improve greenhouse insulation performance, reduce energy consumption, is to improve greenhouse production efficiency of the best way.

Folding durability

Greenhouse construction must consider its durability. Greenhouse durability by the greenhouse material aging resistance, the main structure of the greenhouse capacity and other factors. The durability of the light-transmitting material, in addition to its own strength, is also reflected in the fact that the light transmittance of the material is continuously attenuated over time, and the degree of attenuation of the light transmittance is the decisive factor affecting the service life of the light-transmitting material. General steel structure of the greenhouse life of more than 15 years. Requirements of the design of the wind, snow load with 25 years in a case of maximum load; bamboo structure simple greenhouse life of 5 to 10 years, the design of wind, snow load with 15 years the maximum load.
