Glass glue is a kind of glue with high structural performance. With the wide use now, there is no corresponding detection method on the market. At this time, we need to ensure the quality of glass glue. How to choose red in the procurement process? Let's teach you how to identify the quality of glass glue!
Method for identifying the quality of glass glue
1. Look at the bubbles
The main component of glass glue is silica gel, and the amount of other additives is very small. High purity silica gel has good stability and is less affected by changes in external conditions during storage. When the bottle is mixed with air, there will be no bubbles, and the bubble phenomenon of "snap" and "snap" will appear when the glue is applied.
2. Check the curing effect
After local sizing, check the surface drying time of the glass glue according to the instructions on the product package. If the time is too short or the timeout time is too long, it indicates that the quality of glass glue is wrong; Then according to the curing time specified by the manufacturer, try the hardness and elasticity of the glue by hand, too hard or too soft glue is not a good glue; Cut the glue section and check whether the internal and external curing effect of the glue is consistent. If it is consistent, it is symmetrical inside and outside, which is a good glue.
3, look at the tension and adhesion of the glue
The tensile strength and peel strength of silicone after curing, that is, the adhesive force, will also vary according to the quality of silicone. Generally, high-quality glue has a strong tensile force, a large tensile range and high peeling strength. This glue is not easy to come off and has a long shelf life.
4, smell, especially suitable for acid glue
Because the acid glue contains a certain amount of acetic acid, it will have a sour taste during volatilization. Generally, the good quality glue adds less acetic acid, the acidity is light, and the acidity disappears quickly during the glue curing process; The glue of poor quality is more acidic and lasts longer.
5. Check the particles
Mix fully and evenly, fine and uniform texture, smooth and glossy after curing; The poor quality glass glue can see more particles and impurities, and the surface of the cured rubber strip is not as smooth as that of high-quality glue.
From the above points can identify the quality of glass glue, hope to be helpful to you, thank you for reading, pay attention to Between Building Materials official website for more information!
