双组分硅酮结构胶是由主剂A组分(白胶)和固化剂B组分(黑胶)组成，通过双组分打胶机，按厂家推荐的比例混合均匀后使用。混合后的结构胶经过一段时间固化，获得好的粘接性能和物理性能。但是，如果结构胶混合不均匀后使用，结构胶固化就会出现质量问题。
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.
结构胶混合不均匀，局部会出现白色条纹。在光线比较亮的情况下，更加容易观察。混合不均匀和混合均匀的情况，如下图：结构胶混合不均匀，会出现什么问题呢?结构胶固化后的强度下降，固化交联不完全、严重时候会发粘，无法固化等。
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.

混合不均匀的结构胶有以下四种情况及原因如下：
There are four kinds of non-uniform mixed structural adhesives and the reasons are as follows:
①连续花胶：一般是混合器堵塞、混合器装配错误或者使用的混合单元不够多;
① Continuous gluing: generally, the mixer is blocked, the mixer is wrongly assembled or there are not enough mixing units used;
②断续有规律花胶：与系统性故障有关，如配比泵密封泄漏或者比例架磨损;
② Intermittent regular lac: related to system faults, such as the leakage of proportioning pump seal or wear of proportioning frame;
③断续无规律花胶：与故障有关，如过滤器堵塞/针阀堵塞/压盘故障/配比泵入口堵塞或者密封失效/安全阀及高压球阀失效等;
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短暂停枪后又开枪时，开头出现一段花胶：主要是胶粘度匹配不理想，需要调整系统管道或降低工作压力。
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.
上述出现花胶的四种情况都是通过排除打胶机故障来解决。希望可以帮助到大家，更多精彩内容可以直接关注：http://www.kksmartoffice.com
