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.
Is EVA hot melt adhesive a thermoplastic adhesive or a thermosetting adhesive? Many people who are not very familiar with adhesives do not know the difference between thermosetting adhesives and thermoplastic adhesives. These two types of adhesive products have essential differences, and it is precisely because of these differences that they vary greatly in terms […]
Despite the development of the packaging industry and the increase in various economic options for packaging sealing, hot melt adhesive remains the main packaging material used by many packaging enterprises. Due to the wide variety of hot melt adhesives available nowadays, improper use of hot melt adhesives may lead to unpleasant results for customers. 1. […]
When choosing a supplier of EVA hot melt adhesive for books, periodicals and packaging, the key is to see if it can solve the actual problems on your production line. Don’t complicate the problem. Just focus on the following three key points to make a judgment.
Hot melt adhesive is also known as glue adhesive. They are thermoplastic polymer adhesives that are solid at room temperature. If heated to a temperature above its softening point, the hot melt adhesive will liquefy. Compared with various packaging components, their softening temperatures are relatively low. The liquefaction of hot melt adhesives allows them to […]
