阳光板克重缺乏的危害你知道吗?

来源:http://www.wanzhongyue.com/ 日期:2019-06-25 发布人:admin 浏览次数:

  阳光板温室近年来开展疾速,主要集中在我国北方地域。与玻璃温室相比,其质量轻、骨架资料用量少、造价低、构造件遮光率小、运用寿命长、消费效益好、环境调控才能根本到达玻璃温室的同等程度。阳光板温室选用阳光板质量好坏将直接影响温室的整体质量。质量好的阳光板一、要运用好的聚碳酸酯原资料如拜耳、GE等,二、不添加回收料如光碟料等。三、要有抗UV紫外线共挤层。四、按规范克重量消费。关于前面三点温室行业的同事们多有了共识,但关于第四点,由于温室行业对此问题不太关注,以及有的厂家包括一些知名品牌为了降低本钱挤出一些每平方米克重更低的板材,但上下壁及立筋厚度就更薄,在温室制造中运用这种克重缺乏的阳光板会惹起的很多危害。
  The solar panel greenhouse has been developing rapidly in recent years, mainly in the northern region of China. Compared with the glass greenhouse, the glass greenhouse has the advantages of light weight, less skeleton data, low cost, low shading rate of structural parts, long service life, good consumption efficiency and environmental control. The quality of solar panel used in greenhouse will directly affect the overall quality of greenhouse. Good quality sunshine panels I. To use good polycarbonate raw materials such as Bayer, GE, etc. II. No recycled materials such as CD-ROM materials. Third, there must be UV-resistant ultraviolet co-extrusion layer. 4. Consumption by weight of standard gram. About the first three points, many colleagues in the greenhouse industry have reached a consensus, but on the fourth point, because the greenhouse industry does not pay much attention to this issue, and some manufacturers, including some well-known international brands, have squeezed out some plates with lower weight per square metre in order to reduce costs, but the thickness of the upper and lower walls and ribs is thinner. The use of this kind of sunshine board which lacks weight in greenhouse manufacturing will cause a lot of trouble. How harmful.

  一、 阳光板规范的克重与壁厚:
  1. Gravimetric and wall thickness of sunplate specifications:
  请参照中华人民共和国建筑工业行业规范JG/T116-2012《聚碳酸酯(PC)中空板》
  Refer to JG/T116-2012 "Polycarbonate (PC) Hollow Plate" of PRC Building Industry Code.
  二、降克重所惹起的危害:
  2. Harm caused by weight reduction:
  1、抗冲击才能弱
  1. Shock resistance is weak
  降克重后由于阳光板厚度没有降落,直接结果是上下壁及立筋厚度的降低,使阳光板的抗冲击才能降落。例如:常规双层中空阳光板8mm规范上壁厚度为400μm,在正常状况下能够抗冲击规范是10公斤铁球自在下落2米不击破。规范8mm双层和10mm双层板材,能够抗击普通冰雹的冲击。但假如8mm双层上外表板都没有到达上述的技术指标,普通降克重8mm阳光板的壁厚为300μm左右,结果招致冰雹击穿的状况。

  After weight reduction, the thickness of the sunshine plate did not fall, the direct result was the decrease of the thickness of the upper and lower walls and the vertical ribs, which made the impact resistance of the sunshine plate to fall. For example, the thickness of the upper wall of the 8mm standard for conventional double-deck hollow solar panels is 400 microns. Under normal conditions, the standard for shock resistance is that 10 kilograms of iron balls fall from 2 meters without breaking. The standard 8mm double-deck and 10mm double-deck plates can resist the impact of ordinary hail. However, if the 8mm double-layer upper exterior panel fails to meet the above technical specifications, the wall thickness of the ordinary 8mm sunshine panel with reduced weight is about 300 microns, which results in hail breakdown.

  假如降克重的阳光板上下壁厚到达规范,那其立筋的厚度肯定会降低,立筋主要起到支撑的作用,假如立筋厚度达不到规范,阳光板抗雪载的才能就会降落。阳光板由于保温性能优良,雪在上面不易消融,在高雪载状况下,降克重的阳光板将不堪重负而产生断裂。
  If the thickness of the upper and lower walls of the sunshine plate reaches the norm, the thickness of the upright tendons will certainly decrease. The upright tendons mainly play a supporting role. If the thickness of the upright tendons does not reach the norm, the ability of the sunshine plate to resist snow load will fall. Because of its excellent heat preservation performance, the snow is not easy to melt on it. Under the condition of high snow load, the weight-reducing sunplate will be unbearable and break.
  2、保温系数低
  2. Low thermal insulation coefficient
  降克重的非规范阳光板将无法保证明验保温测试数据的精确性,同时也无法保证运用寿命的稳定.热工计算,供暖系统的根据将得不到计算,供暖设备投入根据将虚有。这样会使整个温室的保温大打折扣。
  Non-standard sunshine panels with reduced weight will not guarantee the accuracy of the test data of the heat preservation, but also the stability of the service life. Thermal calculation, the basis of heating system will not be calculated, and the basis of heating equipment input will be false. This will greatly reduce the temperature of the whole greenhouse.
