The little trick to distinguish the stickiness of the hot melting glue stick
The hot -melt glue rod is environmentally friendly and non -toxic. It can be applied to plastic, metal, wood, paper, toys, toys, electronics, furniture, leather, shoe materials, coating, ceramic, lampshades, pearl cotton, food packaging, speakers and other bonding bondings. With the sustainable development of the economy, hot -melt glue meets the needs of environmental protection, becoming more and more popular, and it is becoming more and more commonly applied to all walks of life. So how to distinguish the stickiness of hot -melt glue sticks? Some people feel that the better the transparency, the better. In fact, this idea is more subjective. Because the batches are different, the rubber sticks are not exactly the same. Sometimes the transparency is sometimes transparent, and sometimes it may not be so transparent, but this does not mean that the stickiness of the rubber stick is not good. Looking at the appearance, it is difficult to distinguish the quality of its viscosity under the naked eyes. Generally, the manufacturer uses the machine to test the stickiness with the machine. The greater the tensile value, the stronger the stickiness.
But if you buy it without this machine, how to test the viscosity of the hot melting glue stick, then Xiaobian will teach you a method to distinguish the stickiness of the hot melting rubber stick.
1. First bend the hot -melt rubber stick with your hands
2. Then loosen one end and observe the rebound situation of hot -melt rubber sticks
The relatively good hot -melt glue rebound speed will be relatively slow, and a slightly lower viscosity can rebound effect is relatively stretch.
The above is the introduction and description of 11×300 Glue Sticks 7 mm Gluesticks 7 mm Varillas De Pistola De Pegamento, I hope it can be helpful to you.
