Sometimes the colloid produced by the two-component glue beater may appear uneven mixing phenomenon, affecting the quality of the product! The following two-component glue maker's small edition will introduce to you the causes of uneven mixing of structural glue!
There are four kinds of uneven mixing structural adhesives and the reasons are as follows:
(1) Continuous gum: generally, the mixer is blocked, the mixer assembly is wrong or the mixing unit is not enough;
(2) Intermittent regular pattern gum: related to systemic faults, such as leakage of seal of proportioning pump or wear of proportioning frame;
(3) Discontinuous irregular pattern gum: related to faults, such as filter blockage/needle valve blockage/platen failure/ratio pump entrance blockage or seal failure/safety valve and high pressure ball valve failure;
(4) When the gun stops for a short time and fires again, a section of gum appears at the beginning: the main reason is that the gum viscosity matching is not ideal, and the system pipeline needs to be adjusted or the working pressure should be reduced.
