Everyone is buyingPhotovoltaic welding ribbon<\/a>When buying photovoltaic welding tape, I don't know what the aging resistance standard is. However, aging resistance is a particularly important indicator when purchasing photovoltaic welding tape. So how to test the aging resistance of photovoltaic welding tape? The following are the industry standards of the China Photovoltaic Industry Association. You can choose products according to the standards.<\/p>\n

The test environment should meet the following requirements:<\/strong><\/p>\n

\u2014\u2014Temperature: 15\u00b0C\uff5e35\u00b0C;<\/p>\n

\u2014\u2014Relative humidity: \u226475%;<\/p>\n

\u2014\u2014Atmospheric pressure: 86kPa\uff5e106kPa.<\/p>\n

Take 3 tin-coated solder tapes with a length of 200mm\u00b12mm as samples and glass, backplane and EVA film of corresponding sizes, and stack them in the order of backplane, EVA film, tin-coated solder tape, EVA film and glass. Laminate and package them in a laminator according to the process parameters that can make the EVA cross-linking degree greater than 80%, and ensure that the distance between the edge of the tin-coated solder tape and the edge of the packaging material after packaging is greater than or equal to 50mm.
\nThe specimens were placed in a climate chamber at room temperature without pretreatment.<\/p>\n
