Prepare for purchaseSealing stripThe first thing we need to care about and understand is how to judge the quality of the sealant. Next, the small part summarizes the conditions of the performance of the sealant strip.
We want to judge the performance of the sealant strip, which is too shallow in terms of shape and color. We should look at the process of making the sealant strip to make a simple judgment. First, we should observe the curing performance of the sealant strip. When the sealant strip is made and cured, we should observe the drying time, anti-sticking time and complete curing time of the sealant strip to judge whether the curing performance of the sealant strip is qualified.
Then observe the extrusion when the glue is squeezed, the extrudability of the rubber strip is judged by the difficulty of the extrusion of the rubber strip. Secondly, it takes 1-2 days for the rubber strip to be fully cured. When the rubber strip is cured, we press the rubber strip with our fingers to feel its hardness, so as to judge the hardness. Thirdly, we need to observe the elasticity and elongation rate of the rubber strip. We can try to pull the fully cured rubber strip, make a judgment on the elasticity and ductility of the rubber strip.
After that, we need thixotropy. After we hit the rubber strip, we put it in a horizontal position. If it does not deform, it means the performance is good. If the deformation is flowing, it means that the thixotropy is very poor.
With these methods, I believe you will how to judge the good or bad of a sealant strip product. If you need, you can contact us. We are a professional manufacturer of sealant strips. We look forward to cooperating with you!
