How much do you know about the complete curing time of AB gl

The complete curing time of AB adhesives adjusted according to the proportion of AB adhesives is much better than that of the original adhesives in terms of viscosity and quality. According to the adjusted mixed adhesives, they can be used in many industries. This article will briefly describe the relevant knowledge of the complete curing time of AB adhesives and the blind spot misunderstanding, etc. The proper understanding of the curing time will greatly control the completion of the viscose fillers, and the general mixing. There are many kinds of plywood, the initial curing time is about 3-5 minutes, and the initial curing time is about 2 hours after coating. Therefore, the adjustment and promotion method when operating AB automatic dispensing machine will be a way to speed up the curing time. The knowledge given below can effectively improve the production efficiency of industries such as waterproof film coating and heat shrinkable film coating for users.
Bicomponent AB glue
Common Misconceptions of Curing Time
At present, the proportion of conventional AB glue is between 1:1 and 3:1, which is suitable for most application industries, and the requirement of this kind of adjustment is lower than that of using AB automatic dispensing machine with two-component dispensing valve to control and adjust. Here we should pay attention to the scope and influence of the complete curing time of AB glue. Take the links of thermal shrinkage film coating as an example, after two to three hours of thermal shrinkage film coating AB glue. After curing, AB glue can be put into use. At this time, the distance between AB glue and its complete curing time is longer, reaching only about 4/5 of the ultimate strength of coating. Observing the protective effects of heat shrinkable film glue, such as bonding strength, aging resistance and corrosion resistance, adjusted according to the proportion of AB glue, we can see that this is a misunderstanding existing in most industries, including the application of waterproof film coating. The problem is that the complete curing time is not equal to the initial curing time.
Large Flow Dual-liquid Dispensing Valve
Ways to Promote Full Curing Time
In order to shorten the complete curing time of AB glue, we should start with the external stimulation operation. The common method is heating to promote the curing time. Generally, the glue coated on the surface of the material after finishing by AB automatic dispensing machine can be baked and heated in a constant temperature oven to promote the curing. There are differences in the complete curing time of different AB glue, so baking. The parameters such as temperature and time to promote curing need to be adjusted according to the proportion of AB glue, otherwise the bonding performance may be affected, which is more obvious in the operation of heat shrinkable film coating and waterproof film coating.
Double-liquid gelatinized dispensing valve
The complete curing time of AB glue takes 8-12 hours, and it needs to be used at 25 degrees at room temperature. If the weather drops, the curing time will be prolonged. When the temperature is low, the complete curing time of AB glue will take 24 hours. The longer curing time of AB glue requires patience to wait for its re-application in industry.
