In the actual pruducing process, it will occur this phenomenon of unevenness gelatinizing or irregular breakpoint occasionally, which always result in these two points as follows:

First, it results in unclean mixing chamber. In the process of after sales, we found that many customers do not care about the equipment maintainance, so the mixing chamber is always dirty and even they do sloppy work for cleaning, which is an extremly irresponsible behavior towards the products quality. Whether the mixing chamber is clean will definitely influence the adhesive strips quality. If it has formed crusts in the mixing chamber, and the crusts become into small uneven size particles under the condition of stirring at a very high speed, if the particals mixes up with glue, there maybe the breakpoints or the colloid surface is matt with impurities on the adhesive strips for blocking the spray nozzle with the crusts, it can block the holes for glue injecting absolutely to make A and B group pressure change and then influence the glue ratio.

Second, to check whether there is enough raw material in the barrel. If it is not enough, it will also occurs the phenomenon of breakpoints. The breakpoints caused by low raw material liquid lever will be always with the phenomenon of blow-by, if we add the raw material, and still we can not solve this problem, then the problem must exist on the rubber valve sealing, if the sealing ring in the rubber valve can not seal well will lead to the compressed air enter into the rubber valve front from the rubber valve, and the breakpoints with bubbles. For the situation, if we change the sealing ring, it is OK.
