First, material reasons
1. The quality problem of the edge sealing strip itself: if the quality of the edge sealing strip is not up to standard, such as insufficient viscosity, viscosity reduction, etc., it will lead to the edge sealing strip not on the glue.
2. The substrate does not meet the standard: if the substrate used does not meet the standard, such as greasy, rusty, dust and other impurities on the material surface, it will cause the edge strip to not be glued.

Second, process reasons
1. Non-standard operation: If the operation of the edge sealing strip construction personnel is not standardized, such as inappropriate temperature, insufficient time, and incorrect positioning, it will affect the bonding effect of the edge sealing strip.
2. Improper process: If the construction process of the edge sealing strip is not carried out in strict accordance with the process, such as insufficient raw material inspection and uneven mixing ratio, it will lead to ineffective bonding of the edge sealing strip.
Third, environmental reasons
1. Temperature and humidity are not suitable: if the ambient temperature and humidity are not suitable, it will affect the construction quality of the edge sealing strip. For example, too low temperature will lead to poor bonding, and too high humidity will lead to weak bonding.
2. Cleanliness problem: If the construction environment of the edge sealing strip is not clean, such as dust, foreign matter and other impurities will affect the quality of the edge sealing, so that the edge sealing strip is not glued.
1, the surface of the flushing strip is not clean: before installation, the dust and oil on the surface of the flushing strip should be wiped clean with a clean rag, so as not to affect the bonding effect. 2, the glue quality is not good: choose good quality, strong adhesive glue, inferior glue is easy to deglue, resulting in the edge of the stick can not stick. 3, glue spread uneven: glue should be evenly spread on the back of the edge, spread too thin or too thick will affect the bonding effect. 4, the installation environment temperature is too low: glue viscosity will be reduced at low temperature, so it should be installed at the appropriate temperature. 5, the punching strip and the bonding surface is not tight: the installation should be the punching strip and the bonding surface should be tightly pressed to ensure that the glue is fully bonded.
