影响pc阳光板透光率的要素有哪些

来源:http://www.wanzhongyue.com/ 日期:2019-04-19 发布人:admin 浏览次数:

  pc阳光板这种板材自面世以来的主要功能便是建筑采光,首先大范围应用的便是农业温室。对于农业温室来说,pc阳光板的透光性、保温性、抗冲击性等是温室工程中首要关注的产品特性,广义上的pc阳光板分为pc实心耐力板和pc中空阳光板,pc实心耐力板的透光度较高可达到90%,与玻璃相媲美;而pc中空阳光板的透光度较高可达83%。需要注意的是,随着pc阳光板的原材料、厚度、结构等变化,其透光率会逐次的降低。以下,我们分别分析原材料、厚度、结构等对阳光板透光率的影响。PC阳光板
  The main function of PC solar panel is building lighting since it came out. First, agricultural greenhouse is widely used. For agricultural greenhouse, the transmittance, heat preservation and impact resistance of PC solar panels are the most important product characteristics in greenhouse engineering. Generally speaking, PC solar panels are divided into PC solid endurance panels and PC Hollow solar panels. The transmittance of PC solid endurance panels is 90% higher than that of glass, and the transmittance of PC Hollow solar panels can reach 83%. It should be noted that with the change of raw materials, thickness and structure of PC solar panels, the transmittance of PC solar panels will gradually decrease. Following, we analyze the influence of raw materials, thickness and structure on the transmittance of solar panels. PC sun panels
  1.原材料对pc阳光板的影响
  1. The influence of raw materials on PC solar panel
  一般的厂家对pc阳光板有几种档次,分别对应的原料有进口全新原料、国产全新原料、以及掺有回收料的产品,由于板材的生产过程简单来说便是原料热熔,然后通过挤出成型,较后共挤抗老化UV涂层、防雾滴层,以及较后的保护膜等工序。那么可以看出,原材料如果本身掺有回收旧料,因为原料的泛黄就会导致成品板材出现发黄的情况,其透光率自然会下降;而具体的透光率要看回收料的质量以及原料中旧料的掺有比例。PC阳光板
  General manufacturers have several grades for PC solar panels. The corresponding raw materials are imported new raw materials, domestic new raw materials and products mixed with recycled materials. Because the production process of plate is simply hot melting of raw materials, then extrusion forming, and finally co-extrusion of anti-aging UV coating, anti-fog droplet layer, and final protective film. It can be seen that if raw materials are mixed with recycled materials, because the yellowing of raw materials will lead to yellowing of finished sheets, and its transmittance will naturally decline; and the specific transmittance depends on the quality of recycled materials and the proportion of used materials in raw materials.

  板材的厚度
  Thickness of sheet metal
  无论是实心耐力板还是中空的阳光板,其透光度都会随着厚度的增加略有降低。耐力板的幅度不会很大,但是阳光板的下降幅度会有很大的变化,主要原因在于阳光板为多层结构,中间为中空的空洞,光照经过每层的折射就会导致较后的透光率发生很大的变化。PC阳光板
  Whether it is solid endurance board or hollow sunshine board, its transmittance decreases slightly with the increase of thickness. The magnitude of the endurance plate will not be very large, but the decrease of the sunshine plate will change greatly. The main reason is that the sunshine plate is multi-layer structure, with hollow holes in the middle. The refraction of light through each layer will lead to a great change in the final transmittance. PC sun panels
  板材的结构
  Structure of sheet metal

  与厚度相同的是,结构的复杂化也会对板材的透光度有很大的影响,其中像三层米字型、四层蜂窝形、六层菱形、甚至八层等,其结构越复杂,光的折射路径就会越复杂,自然其透光率会发生巨大的变化。
  Similar to the thickness, the complexity of the structure will also have a great impact on the transparency of the sheet. The more complex the structure is, the more complex the refractive path of light will be, and naturally the transmittance will change dramatically, such as three-layer meter-shaped, four-layer honeycomb-shaped, six-layer diamond-shaped and even eight-layer.
  以上结论可以得出,我们在选择板材时一定不能单单考虑到其抗冲击、保温等性能,还要综合考虑板材的透光率影响,毕竟pc板材的核心功能便是建筑采光。PC阳光板
  The above conclusions can be drawn that we must not only consider the impact resistance, heat preservation and other properties, but also consider the light transmittance of the board. After all, the core function of the PC board is building lighting. PC sun panels
