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.
How to deal with hot melt adhesive particles burning and smoking? First, give the order of disposal:Immediately lower the temperature of the glue pot by 20 ℃ → exhaust and ventilate → stop adding new glue → remove the coking glue from the pot → check if the temperature control is malfunctioning again.The essence of […]
Direct answer: The back adhesive layer of wireless adhesive packaging for books and periodicals is usually controlled at 0.6-1.0mm, and the side adhesive is 0.2-0.4mm; the thickness of the adhesive dots/lines for corrugated cardboard box sealing is generally 0.3-0.8mm; the thinnest layer for color box pasting is 0.15-0.3mm.The thickness is not necessarily better, sufficient, uniform, […]
Functionality and effectiveness What should be considered when choosing environmentally friendly adhesives? Even at home. For example, if you want to repair a cup, you may use adhesive (a type of contact adhesive), but you will use it in your child’s art project; PVA glue, perhaps using double-sided (pressure-sensitive) tape in the scrapbook. For packaging, […]
Products that have been designed, perfected, manufactured, and inspected to ensure compliance with the highest standards. It’s time for packaging now. The last thing we want is a fragile container that will burst under harsh conditions such as storage, transportation, or shelving. After all, packaging is usually the first impression of a product on potential […]
