How to use hot melt adhesive in the assembly of filter cartridges? Effective filtering is becoming increasingly important in today’s world. Whether it’s the air at home, drinking water in the city, or fuel in heavy vehicles – filters are required to do more. Hot melt adhesive for filter cartridges is essential in filter assembly.
Air filters in vehicles and buildings are high-performance products. They ensure a continuous supply of fresh and clean air. There are various types of filters, usually composed of different materials. The strong hot melt adhesive used for manufacturing filters not only has the characteristic of wide adhesion to different materials, but also helps to provide high-quality products and efficient manufacturing processes.
How to use hot melt adhesive in the assembly of filter cartridges?
Hot melt adhesive or water-based adhesive is used for air, oil, water, and other applications; HVAC The final stage of filter manufacturing. They laminate multiple layers of media together, improving the efficiency of the filter. The selection of filter adhesive is based on the following criteria:
In the air filter manufacturing industry, there are many applications that use hot melt adhesive for filter cartridges. Hot melt adhesives are resistant to high and low temperatures and provide fast curing time, making them widely used in the manufacture of air filters.
When manufacturing air filters, hot melt adhesive with fast curing time is usually the best choice; Because of the fast running filter machine. Hot melt sealed filter frame, laminated filter media, and carefully close the separator.
EVA Hot melt adhesive; And based on APAO Hot melt adhesives have flexibility at low temperatures and are an ideal choice for this application. These adhesives have excellent bonding strength and processing characteristics.
Polyamide based and polyester based; （PET） Hot melt adhesives are also used for air filters in industrial or automotive ventilation systems that must withstand high temperatures. These hot melt adhesives have high chemical and heat resistance; – And it has stronger adhesion to paper and non-woven fabric. Depending on the application, thermal melting point coating, bead coating, roller coating, or spray coating can be used.
Direct answer: FormalHot melt adhesive pelletsThe free sample sending process of manufacturers is usually “proposing requirements → explaining working conditions parameters → confirming sample model and quantity → sending for free (usually SF Express collect or free shipping for the first time) → customer testing on the machine → feedback results before adjustment”. The entire […]
Conclusion: Complianthot melt adhesiveParticles are basically non-toxic at room temperature, and the risks mainly lie in “high-temperature melting” and “ingestion” Conventional EVA and APAO based hot melt adhesive particles are 100% solid content, solvent-free bulk adhesives that are stable at room temperature, non-volatile, and safe for daily contact and storage. What really needs to be […]
There are three commonly used testing methods for the peel strength of hot melt adhesive particles:180 ° peel off(Soft substrate to soft substrate, such as laminated paper, non-woven fabric)90 ° peeling(Soft substrate to hard substrate, such as cardboard bonding) andT-shaped peeling(Used when the flexibility of the substrate on both sides is similar). The most commonly […]
The common quality problems of wireless binding hot melt adhesive mainly include page dropping, uneven back, broken book core, bubbles, and perforation at both ends of the book. They often appear on single or multiple banks, mainly due to the following reasons: 1、 Analysis of Page Dropping Reasons (1) The milling groove is too shallow […]
