How to use filter hot melt adhesive

1. You need to communicate with the hot melt adhesive supplier about your bonding requirements (filter paper material, glue toughness, glue curing time, finished product testing requirements, etc.), and provide reasonable filter element hot melt adhesive use.
2. Adjust the machine’s sol temperature and glue application amount, put the hot melt adhesive into the glue pot, and start applying the glue after the glue melts to the specified temperature.
3. After the hot melt adhesive is applied to the bonding material, a certain amount of pressure needs to be applied to the material to facilitate better penetration of the glue.
4. When the temperature of the hot melt adhesive gradually cools down, the materials will be bonded together, and the bonding process will be successfully completed.

Application notes

1. This air filter can be used in laboratories, sterile rooms, farms, car air conditioners, household air conditioners, household air purifiers, etc.
2. Before making a flat filter element, a small batch test is required to ensure that the amount of glue sprayed is appropriate to avoid glue breakage.
3. The substrate structure and operating environment will affect the bonding effect. It is recommended to try it first. The bonding surface should be free of dust and grease.
4. It is recommended to use an ambient temperature of 15-30℃. If the ambient temperature is lower than 10℃, the ambient temperature needs to be heated.
5. Keep the glue tank clean. During normal use, if the amount of glue is less than half, glue particles must be added in time.

Filter hot melt adhesive FAQs

Q1. Why does the filter fold appear “disconnected”?

A1.a. The selected filter hot melt adhesive lacks flexibility. b. Insufficient amount of glue applied. c. Insufficient pressure applied after glue application. d. The ambient temperature is too low and the hot melt adhesive solidifies prematurely.

Q2. Why does the filter hot melt adhesive smell pungent?

A2.a. EVA hot melt adhesive is selected, not polyolefin hot melt adhesive. b. The filter hot melt adhesive supplier uses unqualified raw materials. c. The sol temperature is too high and the hot melt adhesive has been carbonized.

Q3. Why can’t the filter hot melt adhesive bond the material?

A3.a. The melt temperature of the hot melt adhesive is set too low. b. The conveyor speed is too slow. c. Insufficient amount of glue applied. d. The ambient temperature is too low, resulting in a low surface temperature of the bonded material. e. Insufficient pressure applied.
