The application of filter element adhesive

Application of filter element adhesive. Filters are also known as filter elements. Common filters are divided into two categories: air filters and oil filters. Air filters are mainly used to purify air. It is generally used in automobiles. According to their uses, they can be classified into air filters and air conditioning filters.

The main function of a car air filter is to purify the air inside the engine and prevent dust in the air from causing damage to the engine. Air filter = The filter through which external air enters the front of the engine = air grille.

The main function of a car air conditioning filter is to purify the air inside the vehicle. Air conditioning filter = Pollen filter = Filter before outdoor air enters the driver’s cabin air conditioning system = air conditioning grille.

According to appearance, they can be classified into high-efficiency filters with separators and high-efficiency filters without separators. Among them, the air filters used for partitions are made of aluminum strips, etc., and are relatively heavy. The partition is made of hot melt adhesive and is lightweight.

The oil filter is mainly used to block dust, metal particles, carbon deposits, fume particles, etc., and is mainly used to protect the engine. Generally, PA polyamide hot melt adhesive is mainly used. PA type hot melt adhesive features high-temperature resistance and oil resistance.

Filter element adhesives generally use EVA hot melt adhesive and PO polyolefin hot melt adhesive. This hot melt adhesive features rapid curing and is suitable for mass production, especially for high-efficiency filters without separators. This glue mainly serves to fold the lines of filter paper, fold the edges of filter paper, fix the mesh film, and fix the filter element frame, etc.
