纹络型温室顶部覆盖阳光板的优劣怎么区分?

来源:http://www.wanzhongyue.com/ 日期:2021-09-11 发布人:julong 浏览次数:

在纹络型玻璃温室大棚的顶部有两种覆盖材料,其中一种是玻璃、另一种是阳光板。玻璃的优点是透光率高、物理性状稳定,但是保温隔热性差,对于北方一些地区业主来说能耗较高,所以北方的温室大棚种植者还喜欢用阳光板作为覆盖材料。
There are two covering materials on the top of the corrugated glass greenhouse, one is glass and the other is sunlight plate. The advantages of glass are high light transmittance and stable physical properties, but poor thermal insulation. For owners in some areas in the north, energy consumption is high. Therefore, greenhouse growers in the north also like to use solar panels as covering materials.
阳光板具有双层中空结构,保温性好,结构牢固、安全性高,但是近几年有一些厂家或者是温室的承建商为了拉低造价,低价中标使用一些劣质的阳光板,导致一些温室大棚顶部板材在使用几年后就会出现发黄甚至破裂的情况,那么如何区分阳光板的优劣呢,今天由广源温室于工分享大家几个简单的小知识。
The solar panel has a double-layer hollow structure with good thermal insulation, firm structure and high safety. However, in recent years, some manufacturers or greenhouse contractors have won the bid to use some low-quality solar panels at a low price in order to reduce the cost, resulting in yellowing or even cracking of the top panels of some greenhouses after several years of use. So how to distinguish the advantages and disadvantages of solar panels, Today, Yugong of Guangyuan greenhouse will share some simple knowledge.
国标优质的阳光板透明度在百分之八十以上,并且用肉眼看上去比较的明亮,清澈,没有气泡和杂质。使用回收材料的阳光板便面会发钨。
The transparency of the national standard high-quality sunlight plate is more than 80%, and it looks bright and clear with the naked eye, without bubbles and impurities. The sun board with recycled materials will emit tungsten.
撕开保护膜看板材,无杂质无颗粒物的板材是全新原料,相反有杂质异物的就是添加了回收料,回收料添加得越多杂质越明显板材质量越差。

Tear off the protective film to see the plate. The plate without impurities and particles is a new raw material. On the contrary, the recycled material is added. The more the recycled material is added, the more obvious the impurities are, and the worse the plate quality is.
有无防雾滴,在阳光板的内面放置在盛有热水的水杯上,内表面不会起雾气,这种是有防雾滴性能的,是正规产品。
Whether there is anti fog drop, place it on the water cup containing hot water on the inner surface of the sunlight plate, and the inner surface will not fog. This kind of anti fog drop performance is a regular product.
阳光板的重量,目前国标阳光板的理论重量是1.4kg/平方米,如果重量较轻会导致阳光板表面比较容易破裂,强度不够。
At present, the theoretical weight of the national standard sunshine plate is 1.4kg/m2. If the weight is light, the surface of the sunshine plate will be easy to crack and the strength is not enough.
弯折PC阳光板样块,易脆折的板材质量越差,PC聚碳酸酯板材是有较好韧性的。如果板材非常容易断裂,说明不是纯PC颗粒原材料,也就是添加了回收料的阳光板。
When bending PC sunshine plate sample block, the worse the quality of brittle plate, PC polycarbonate plate has better toughness. If the plate is very easy to break, it means that it is not a pure PC granular raw material, that is, a sunshine plate with recycled materials added.
关注价格,价格比市场行情低太多的阳光板一定是使用劣质原材料甚至是回料制造而成的。
Pay attention to the price. The sunlight board whose price is too low than the market price must be made of inferior raw materials or even recycled materials.
