Introduction
As we all know, the relationship between product and function: product is the carrier of function, and function is the intrinsic value of product! If any product leaves the function, its "value V(RF/C)" will be zero, and the product will be meaningless; But at the same time, we should also prevent excessive or insufficient functions, which is what we usually call "cost performance". The following is a brief introduction to the product types of fabric roller blinds on the market (as shown below).
Then, for the external sunshade of fabric UV blocking curtains for living room, when the sunshade is needed, opening the fabric roller blinds will effectively reduce the direct sunlight on the transparent parts of doors, windows and curtain walls through "reflection and absorption" to reduce the solar heat gain coefficient, thus reducing the indoor cooling load; At the same time, she will also allow an appropriate amount of sunlight to enter the room through the transparent parts of doors, windows and curtain walls through "transmission" to reduce the indoor lighting load; It can also reduce the convection times of doors and windows and the outer surface of curtain wall at the right time, thus further reducing the indoor cooling and heating load; In winter, when it is necessary to get light and heat, put away the fabric roller blinds for shading, so that the transparent parts of doors, windows and curtain walls can fully get light and heat, and reduce the indoor heating load;
Photothermal performance：
Based on the principle of "a cow leads its nose", this paper studies and solves the indoor cold and heat load caused by the solar heat gain of the transparent parts of building doors, windows and curtain walls. The sun is the largest light source in nature, and sunlight is electromagnetic wave. More than 99% of the total radiant energy is in the range of 0.15 ~ 4 μ m, and it is mainly distributed in the visible region, red and ultraviolet regions. The band with the largest heat is the visible light region, accounting for about 50% of the total solar radiation energy, followed by the infrared region, accounting for about 43%, and the solar radiation energy in the ultraviolet region is very small, accounting for only about 7% of the total;
However, the wavelength range of solar radiation that really reaches the ground is about 0.295 ~ 2.5 μ m, and solar radiation with wavelengths shorter than 0.295 μ m and larger than 2.5 μ m cannot reach the ground due to the strong absorption of ozone, water vapor and other atmospheric molecules in the earth's atmosphere (as shown in the following figure).
Wind resistance. The excellent wind resistance of the fabric roller blind is due to the good mechanism design and manufacture of the system (as shown in the following figure) and the high performance of the fabric itself, such as: radial/weft breaking strength ≥ 1600/1200 N; Radial/weft tearing strength: ≥ 363/180 N; Elongation: ≤ 4%; Thus, it is ensured that the fabric roller blind can still work normally within the calculated wind load of 1500pa. Of course, in the process of building application, careful calculation is needed to adapt the installation nodes and installation auxiliary materials;
Security：
This safety index involves many product safety factors, such as health, wind resistance, electric shock caused by electric leakage of motor, fire resistance of fabric, and possible pinch protection during use. Health. General fabric materials are easy to breed mold under certain humidity and temperature, which affects human health. The fabric roller shutter is made of high-quality fabric, made of PVC covered with glass fiber and treated with special technology, which has more than 99% antibacterial ability and effectively prevents the growth of mold;
Durability indicators mainly involve: mechanical durability and color fastness. The mechanical durability is mainly determined by the rationality of the product system, and the mechanical durability of this product should not be less than 15,000 times (level 3 or above in the People's Republic of China (PRC) building industry standard JG/T274-2018 "General Technical Requirements for Building Shading", and the corresponding number is more than 10,000 times); The color fastness should not be lower than the standard 4, but actually it is better to be above 7;
Endurance：
Other：
In addition to the first to the fifth, the fabric UV blocking curtains for living room meets the requirements of rigid sunshade and also has the functions of ventilation, landscape penetration and mosquito prevention.
