雙組分硅酮結構膠是由主劑A組分(白膠)和固化劑B組分(黑膠)組成，通過雙組分打膠機，按廠家推薦的比例混合均勻后使用。混合后的結構膠經過一段時間固化，獲得好的粘接性能和物理性能。但是，如果結構膠混合不均勻后使用，結構膠固化就會出現質量問題。
The two-component silicone structural adhesive is composed of main agent a (white adhesive) and curing agent B (black adhesive). It can be used after being evenly mixed according to the proportion recommended by the manufacturer through two-component beater. After curing for a period of time, good adhesion and physical properties were obtained. However, if the structural adhesive is used after uneven mixing, there will be quality problems in the curing of structural adhesive.
結構膠混合不均勻，局部會出現白色條紋。在光線比較亮的情況下，更加容易觀察。混合不均勻和混合均勻的情況，如下圖：結構膠混合不均勻，會出現什么問題呢?結構膠固化后的強度下降，固化交聯不完全、嚴重時候會發粘，無法固化等。
The mixing of structural adhesive is uneven, and white stripes will appear locally. It is easier to observe when the light is brighter. The situation of uneven mixing and even mixing is shown in the following figure: what will happen if the structural adhesive is mixed unevenly? The strength of the structural adhesive decreases after curing, the curing cross-linking is incomplete, and it will stick when it is serious, and it cannot be cured.

混合不均勻的結構膠有以下四種情況及原因如下：
There are four kinds of non-uniform mixed structural adhesives and the reasons are as follows:
①連續花膠：一般是混合器堵塞、混合器裝配錯誤或者使用的混合單元不夠多;
① Continuous gluing: generally, the mixer is blocked, the mixer is wrongly assembled or there are not enough mixing units used;
②斷續有規律花膠：與系統性故障有關，如配比泵密封泄漏或者比例架磨損;
② Intermittent regular lac: related to system faults, such as the leakage of proportioning pump seal or wear of proportioning frame;
③斷續無規律花膠：與故障有關，如過濾器堵塞/針閥堵塞/壓盤故障/配比泵入口堵塞或者密封失效/安全閥及高壓球閥失效等;
③ Intermittent irregular glue: related to faults, such as filter blockage / needle valve blockage / pressure plate failure / inlet blockage of proportioning pump or seal failure / safety valve and high pressure ball valve failure, etc;
④短暫停槍后又開槍時，開頭出現一段花膠：主要是膠粘度匹配不理想，需要調整系統管道或降低工作壓力。
④ When the gun was stopped for a short time and fired again, a section of glue appeared at the beginning. The main reason was that the glue viscosity matching was not ideal, and it was necessary to adjust the system pipeline or reduce the working pressure.
上述出現花膠的四種情況都是通過排除打膠機故障來解決。希望可以幫助到大家，更多精彩內容可以直接關注：http://www.xyspace.net
