How to choose suitable hot melt adhesive pellets for EPE pearl cotton industry?

EPE is a foaming polymer. EPE is soft in appearance and shockproof, and is widely used in the carton packaging industry. For example: TV sets, eggs, fruits, glass, etc. need to be transported over long distances in the packaging of goods to protect the goods.

The appearance of pearl cotton presents different appearances according to different needs, such as porous pearl cotton, ordinary pearl cotton, colored pearl cotton, super large pearl cotton and other different appearance pearl cotton. So how are these pearl cottons with different appearances produced? The answer is to cut through the machine, and then glue it manually to achieve the appearance we want.

So how does the pearl cotton factory choose the right hot melt adhesive?

1. The company's product positioning can often directly determine which type of pearl cotton hot-melt rubber particles to use. For example, the company only needs to be able to stick, and there are no other special requirements for the pearl cotton rubber particles. Then just choose the common type of eva Hot melt adhesive pellets. Of course, the most basic hot-melt adhesive pellets must be environmentally friendly.

2. The company positions its products as high-end. At this time, it is enough to directly choose polyolefin type hot melt adhesive. Because apao polyolefin type hot melt adhesive particles have the characteristics of good viscosity, odorless, non-smoke, and non-drawing. It is more expensive than the ordinary eva type hot melt adhesive, which is also a reflection of what you pay for.

3. It can be purchased according to individual requirements. For example, you need yellowing resistant rubber particles, non-drawing rubber particles, odorless rubber particles, non-smoke rubber particles, good viscosity, fast curing speed, and slow curing speed. The suitable hot melt adhesive particles can be selected according to the specific one-way requirements.

Adjusting skills of roller hot melt glue machine for pearl cotton

1. Increasing the temperature of the roller/glue tank will delay the curing speed. Decreasing the temperature of the roller/glue tank will delay the curing speed. The temperature of the roller should not be too high to avoid scalding the pearl cotton, and the temperature of the glue tank should not be too high to avoid carbonization of the pearl cotton particles.

2. Roller height adjustment. The higher the roller, the smaller the amount of glue, and the lower the roller, the larger the amount of glue.

3. Adjustment of speed. Generally, the slower the rotation speed, the more the amount of glue applied. On the contrary, the faster the rotation speed, the less the amount of glue applied.

The roller hot melt glue machine of the general pearl cotton manufacturer has a long service life, which causes the temperature of the glue tank and the roller temperature displayed on the instrument to be inconsistent with the actual temperature. At this time, you need to use an infrared thermometer to test, only in this way can you ensure that the hot melt adhesive particles are always in good condition.

In addition, when purchasing hot-melt adhesive pellets, pearl cotton manufacturers must choose regular hot-melt adhesive manufacturers, so that the stability and safety of the products can be guaranteed.
