In many outdoor sunshade application scenarios, black sunshade net often needs to be spliced according to the actual use area to meet the needs. The quality of its splicing process has an important impact on the overall sunshade performance.
First of all, the choice of splicing method is crucial. Common splicing methods are stitching splicing and buckle splicing. Stitching splicing usually uses special stitching to tightly sew the edges of two sunshade nets together. The advantage of this method is that the splicing is relatively tight, which can effectively reduce the light penetration caused by the gap. However, if the material of the stitching is not properly selected, such as not having good weather resistance, after long-term sunlight exposure and wind and rain, the stitching may age and break, causing cracks at the splicing, thereby affecting the overall sunshade performance.
Buckle splicing uses special buttons or clips to connect the sunshade net. Its advantage is that it is relatively easy to install and disassemble, which facilitates the reuse and partial replacement of the sunshade net. However, there may be a certain gap in the fastening part. If the spacing between the buttons or clips is too large or the fastening is not tight, light will easily leak in from these gaps, reducing the sunshade effect. For example, when using black sunshade net in agricultural greenhouses, if there is too much light leakage at the joints, the local temperature control in the greenhouse will be uneven, affecting the growth of crops.
Secondly, the quality of the splicing material has a direct relationship with the sunshade performance. Whether it is stitching or fastening accessories, their own light-shielding, durability and anti-aging properties need to be considered. If the light transmittance of the splicing material itself is high, even if the splicing process is good, the light-shielding rate of the overall sunshade net will be affected. Moreover, poor-quality splicing materials are easily damaged in outdoor environments, which in turn destroys the integrity of the sunshade net and leads to a decrease in sunshade performance.
Furthermore, the tightness of the splicing is a key factor. During the stitching or fastening process, the technical level and degree of operation standardization of the operator determine the tightness of the splicing. If wrinkles, uneven overlaps or large gaps occur during splicing, light will be refracted and scattered in these uneven or gapped areas, increasing the amount of light transmission and weakening the sunshade effect. For example, in the construction of sunshade facilities in large outdoor parking lots, if the black sunshade net is not spliced tightly, the direct sunlight area will increase, and the degree of sun exposure to the vehicle will increase.
In addition, the sealing treatment of the splicing joints should not be ignored. For some high-demand sunshade application scenarios, such as outdoor storage sunshade of precision instruments, it may not be enough to rely solely on conventional splicing methods. It is necessary to use sealants or other sealing materials at the splicing joints to further reduce the intrusion of light and heat from the splicing gaps and ensure the stability and reliability of the overall sunshade performance.
From the perspective of long-term use effects, the splicing process also needs to take into account the elasticity of the sunshade net. Since the black sunshade net may undergo a certain degree of expansion and contraction deformation under different ambient temperature and humidity conditions, if the splicing process cannot adapt to this change, the splicing joints may become loose, cracked or deformed over time, resulting in a gradual deterioration of the sunshade performance.
The splicing process of black sunshade net affects the overall sunshade performance in many aspects. In practical applications, it is necessary to comprehensively consider factors such as splicing method, material quality, tightness, sealing treatment and the expansion and contraction characteristics of the sunshade net to ensure that the black sunshade net always maintains a good sunshade effect during long-term use and meets the sunshade needs in different scenarios.
