     环氧ab胶的固化主要是A组份的环氧树脂和B组份的固化剂进行的化学反应,既然是化学反应,那么只有当环氧树脂和固化剂全部都反应完了,就算是完全固化了,但这都是理想状态,实际也是不可能的,但是我们也要尽量让其反应的尽可能的完全,这样才能更好的发挥AB胶水的固化后特性;ab胶如何配比呢?这个一般厂家都会有一个推荐的配合比例,一般我们使用过程中严格按厂家推荐的比例进行作业就可以了;不可依个人喜好或为了加快前期的固化反应速度来随意调整配合的比例。

     那么,环氧树脂ab胶配比不准确会有什么影响呢?会产生什么问题呢?华创材料为您解答:


1、胶水不固化,永远都是液体状或半液体状或泥状;可能原因:固化剂放得太少或放得太多(配比相差很大)


2、本应为硬胶的胶水固化后是软的,可能原因:胶水配比不正确:如未按重量比配比或偏差较大(固化剂多了或少了都会有可能有此情况)


3、有些胶水固化了,有些胶水没有固化或固化不完全,可能原因:搅拌不均匀


4、固化后胶水表面很不平整或气泡很多,可能原因:前期固化太快,固化剂加得过量有可能产生


5、固化后胶水表面有油污状,可能原因:固化剂过量或其它因素影响


6、固化后的结构性差,粘接力低下


等等,通过上面的了解,我们知道了ab胶配比正确的重要性,所以在操作使用过程中,我们一定要严格按照厂商的要求进行配比作业,以避免产生不必要的问题!

The curing of epoxy ab glue is mainly A component of the curing agent of epoxy resin and B component chemical reaction, since is A chemical reaction, so only when epoxy resin and curing agent all finished reaction, even completely cured, but it is the ideal state, actually also is impossible, but we also try to make the reaction as completely as possible, so as to better play to the ab glue after curing characteristics; Ab glue ratio? The general manufacturers will have a recommended by mixing proportion, normally we use process strictly manufacturers recommended according to the proportion of homework is ok; According to individual be fond of or early in order to accelerate the curing reaction speed to adjust the proportion of.

So, the ratio of epoxy resin ab glue what effect will not accurate? Will have what problem? China and the material for you to answer:


1, glue not cure, always will be a liquid or a liquid or mud; Possible reasons: curing agent put too little or too much difference in ratio ()


2, this should be a hard rubber glue after curing is soft, possible reasons: the ratio of glue is not correct: such as not according to weight ratio than or deflection (curing agent is more or less will likely have this situation)


3, some glue curing, some glue not cured or curing incomplete, possible reasons: don't stir evenly


4, after curing glue surface is very uneven, or many bubbles, possible reasons: the early stage of the fast curing, curing agent and is likely to produce excess


5, after curing glue surface with oil pollution, possible reasons: excessive curing agent, or other factors


6, after curing structural difference, stick relay is low


, etc., through the understanding of the above, we know the importance of ratio of ab glue is correct, so in the process of operation, we must be in strict accordance with the requirements of the manufacturers matching operation, to avoid to produce needless issue!
