该如何减少pc阳光板的老化问题呢?

来源:http://www.wanzhongyue.com/ 日期:2020-09-01 发布人:julong 浏览次数:

当pc阳光板长时间户外环境中使用时,由于受到了风吹日晒,一般的阳光板会很快的老化。由此说明,太阳辐射经过促进外表网纹形成对pc阳光板将会造成严重的危害,进一步使得水、尘埃、化学物质等对阳光板腐蚀。那该如何减少pc阳光板的老化问题呢?
When PC sunshine board is used in outdoor environment for a long time, due to the wind and sun, the general sunshine board will quickly aging. This shows that solar radiation will cause serious harm to the PC solar panel by promoting the formation of the surface netting, and further cause the corrosion of water, dust, chemical substances and so on. So how to reduce the aging problem of PC solar panels?
通过以上的情况说明,pc阳光板的老化速度很大程度上取决于环境因素,包括地理位置、海拔、气候的变化等。为了减缓pc阳光板的老化,对其朝阳面进行防紫外线处理。
According to the above situation, the aging speed of PC solar panels largely depends on environmental factors, including geographical location, altitude, climate change and so on. In order to slow down the aging of PC sunshine board, the sun facing surface of PC was treated with UV protection.
通常有两种途径可以做到,有一种方法就是在原料中添加紫外线维护层专用母料,然后通过挤出工艺制作成具有抗紫外线功能的pc阳光板;另一种是在成型后的阳光板面层上增加一层抗紫外线涂层,从而达到抗紫外线作用。
There are usually two ways to do this: one is to add a special masterbatch for UV maintenance layer into the raw material, and then make a PC sunshine board with anti ultraviolet function by extrusion process; the other is to add a layer of anti ultraviolet coating on the surface layer of the formed sunlight board, so as to achieve the anti ultraviolet effect。
这2种方法不管是哪一种方式,除了要选用高品质的抗UV膜和优质树脂外,其生产固化度的控制也非常关键,因为pc阳光板的固化度提高的话,其硬度、机械强度也会很高,相对比较脆化。
No matter which way these two methods are, in addition to selecting high-quality UV resistant film and high-quality resin, the control of curing degree is also very important, because if the curing degree of PC sunshine board is improved, its hardness and mechanical strength will also be very high, relatively brittle.
还有的阳光板厂家,为了增加板材的耐性而增加了增塑剂,这样的做法不仅会影响pc阳光板的强度,还会使它的耐老化性和使用寿数会大打折扣,可以想到这样的阳光板自然经受不住环境条件的影响而过早老化。
There are also manufacturers of sunlight plate, in order to increase the resistance of the board and add plasticizer, this practice will not only affect the strength of PC sunshine plate, but also make its aging resistance and service life will be greatly reduced. It can be thought that such a sunlight plate can not withstand the impact of environmental conditions and premature aging.
所以在选择户外使用的pc阳光板的时候,一定要选择品质优异、性能良好的阳光板。而且在安装使用的时候也要留意,要将板材具有抗紫线层面向上朝向阳光板照射的方向,并避免各种酸碱物质与其接触
Therefore, when choosing the PC sunshine board for outdoor use, we must choose the sunshine board with excellent quality and good performance. And in the installation and use of time should also pay attention to the plate with anti violet line layer upward toward the direction of sunlight, and avoid all kinds of acid and alkali substances contact with it
