很多人说tinting好, 可以阻挡紫外线, 澳洲皮肤癌太多了, 所以要tinting. ok, 那就tinting吧. 我也就这样自己给自己的车tinting了.今天翻贴爬楼看到又有人说到这个, 我就搜了下相关信息, 得到如下内容:
There are 3 types of ultraviolet radiation, but only two reach the earth's surface. These are UVA and UVB. UVC is filtered out by the ozone layer.
UVA mostly causes skin ageing and research has now shown that it is also likely to cause skin cancer. UVB causes redness and sunburn and is a major risk factor for all types of skin cancer.
Most glass used for windows blocks UVB but not UVA. This means that although glass might reduce the risk of sunburn, it does not prevent long term damage from UVA. So, if you are driving long distances or sitting in your conservatory every day for long periods of time, you need to make sure you are using sun protection on sunny days.
紫外线是包含2种一起, uvc是还没落到地面就被咔嚓掉了; 所以平常看防晒品广告只有提及uva和uvb, 一直不明白这2者区别, 看了才懂, 原来一个是负责让你得癌, 一个是负责让你晒伤感到痛的 (所以你感到皮肤刺痛不是就得癌咯, 再所以你以为自己皮肤不刺痛也不说明你远离皮肤癌咯, tinting的效果主要其实是减少可见光让你不会感觉到阳光的刺痛而已).
As the Cancer Council Australia Position statement states1:
UV radiation levels inside a car vary depending on factors such as whether the side windows are open or closed and the orientation of the vehicle with respect to the sun.
They are generally much lower than outside in full sunlight, varying from as low as 4% up to 50% of the ambient UV radiation outside the vehicle.
Clear autoglass (side windows) blocks about 97% of the UVB radiation and about 37% of UVA radiation.
Laminated windscreens block all of the UVB radiation and about 80% of the UVA radiation.
Clear windscreen films can reduce the transmission of UVR further so that as much as 97% of the UVA is blocked. This depends on the quality of film used.
Clear or tinted films can also reduce the amount of UVA and UVB penetrating through the side glass. The amount of protection varies with different products.
既然连清晰透明的玻璃都能阻挡掉97%的uvb和37%的uva :o ,那么tinting的目的显然就不是为了uvb了, 而是为了排除或者减弱uva.看到倒数第二条说的没, 风挡贴膜可以阻挡97%uva(用的多挡的多), 而边玻璃tinted film阻挡uva就要看是什么样的产品了. 看大家很乐忠于tinting,而大部分tinting部位都集中在边玻璃,
最后要说一下, 和很多人一样, 都觉得车窗贴得越黑越凉快, 现在看来这完全没有必要 (由于本人口齿不清,思维混乱,导致下面有群众反映, 贴黑了就是凉快,扯到可见光去了, 特此说明, 这里还是在讨论uvb, 和tinting没关系, 本身玻璃就能挡掉让你刺痛的uvb了没错, 如果你要车内温度凉快,请随便加黑减少可见光; 但请注意贴太黑有可能触犯法律( vic规定车窗贴膜不能使用低于65%透光率的贴膜, 想要有效防紫外, 就请选择好的产品吧. 这个就靠自己google或者热心人分享了. |
