What are the uses of filter gel? An air filter is a component used to purify the air. Filters are generally used in farms, laboratories, sterile rooms, car engines, car air conditioners, household air conditioners, household air purifiers, etc.
The commonly used filter cartridge adhesive is the high-efficiency filter in fiberglass. We also refer to it as a planar filter or plane filter. The adhesive part is the part of the adhesive line in the middle, usually called the folded line adhesive. This part of the glue is automatically applied by the machine. This type of hot melt adhesive particles generally uses EVA type fast drying hot melt adhesive particles or APAO type fast drying polyolefin hot melt adhesive particles. The filter element that requires bonding must have toughness, and the adhesive line in the middle must not break or bond. The black part on the outside is made of sponge or plastic, which is glued on with a hot melt adhesive stick.
Activated carbon filter cartridge, this filter cartridge adhesive needs to be adhered to the black rubber shell and sponge. Generally, hot melt adhesive with high viscosity can be used without special requirements.
This cylindrical filter is almost identical to a flat filter, requiring folding and rolling into a cylindrical shape, which requires the high tension performance of hot melt adhesive. Generally, applying glue after nitrogen foaming can greatly reduce the amount of glue used. Generally, it is APAO polyolefin hot melt adhesive particles.
Some cylindrical filters are sealed with black non-woven fabric edges, which can be directly sealed with ordinary hot melt glue sticks or hot melt glue particles, while others are sealed with plastic covers, usually made of ABS material or PP material. This requires polyolefin hot melt adhesive rods or particles with good viscosity. But the temperature should not be too high to avoid burning out the plastic cover.
This type of filter is usually very sticky. Hand glue guns can use regular hot melt glue sticks or regular models of hot melt glue balls.
Why does pearl cotton hot melt adhesive have wire drawing? During the process of gluing pearl cotton with a drum hot melt glue machine, some customers may find that the hot melt glue has a wire drawing phenomenon. The wire drawing of the hot melt glue not only affects the construction efficiency, but also affects […]
How to choose environmentally friendly hot melt adhesive? At present, the functions and applications of hot melt adhesive have received widespread attention, but the environmental issues of hot melt adhesive are often overlooked. Has environmental protection become a bottleneck for the further development of adhesives? Solving the problem of environmental pollution has become an urgent […]
The types of hot melt adhesive include: ethylene vinyl acetate (EVA) adhesive Ethylene vinyl acetate (EVA) is a polymer based material used for standard packaging of industrial hot melt adhesives. EVA produces high-performance and highly competitive packaging hot melt additives. Ethylene vinyl acetate is considered the primary choice for many applications as it offers one […]
The flowability of hot melt adhesive particles has an impact on the quality of glue and adhesive. Hot melt adhesive has poor fluidity and can also cause stretching problems or mismatch with mechanical efficiency. 1. Sol temperature; Hot melt adhesive is very sensitive to temperature, and changes in temperature can alter the structure of the […]
