Analysis of Hot Melt Adhesive Particles: Reasons for High Adhesive Temperature and Bubbles.
Hot melt adhesive particlesare a type of plastic adhesive. Their physical state changes with temperature within a certain temperature range. The chemical properties of hot melt adhesive are non-toxic and odorless. It is an environmentally friendly chemical.
Hot melt adhesive is usually melted by heating the adhesive. After tuberculosis, the colloidal state changes to liquid state. It can be made through coating, spraying, and peeling.
During the production process of the hot melt adhesive machine, bubbles may sometimes appear. What is the reason for the formation of bubbles? The reason for the formation of bubbles may be due to the presence of bubbles in the colloid itself, the presence of bubbles after melting, or the presence of moisture in the colloid, which can easily form bubbles when heated.
Another type is that the hot melt adhesive is damaged due to high temperature, decomposing to produce gas and bubbles. Therefore, the reason why hot melt adhesive decomposes due to high temperature depends on the composition of the hot melt adhesive.
This type of hot melt adhesive particle is composed of thermoplastic elastomer, softener, and resin. Resin and plasticizer are small molecules. There are many unsaturated bonds in the molecule. Molecular bonds are unstable. When heated to very high temperatures, they react with oxygen in the air.
It produces gases such as carbon dioxide, which in turn creates bubbles.
Direct answer: The impact is significant. For every 10 ℃ decrease in workshop temperature,hot melt adhesiveThe actual opening time has been reduced by about 30-40%; When the relative humidity exceeds 75%, the moisture content of the paper increases, and the wetting and penetration of the adhesive will deteriorate. The performance of the same batch of […]
Handbags, as a packaging product, are widely used in the natural market, which is beneficial for the hot melt adhesive in the handbag market. There are many grades of handbags themselves, and the packaging displayed also varies. To know which hot melt adhesive is good for handbags, first you need to know the grade of […]
