What are the hot melt adhesives for filters? 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.
1、 Hot melt adhesive for flat filter
The commonly used filter element is a high-efficiency filter made of 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.
2、 Activated carbon filter hot melt adhesive
Activated carbon filter element, this filter element needs to be adhered to a black rubber shell and sponge. Generally, hot melt adhesive with high viscosity can be used without special requirements.
3、 Hot melt adhesive for cylindrical filters
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 the filter’s 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.
4. No Line FilterHot Melt Adhesive
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.
For EVA hot melt adhesive used for binding, it can be divided into high-speed adhesive and low-speed adhesive according to different curing times. The curing speed of high-speed adhesive is slightly faster, while the curing speed of low-speed adhesive is slightly slower. According to the material of the book, it is divided into laminated paper […]
Hot melt adhesive is a type of thermoplastic that melts into a solid state by heating and applying temperature. When the adhesive begins to solidify (heat loss) before the material is bonded, cold bonding occurs, which can lead to bonding failure. Usually, it appears to be firmly adhered after bonding, but the bonding strength may […]
What are the uses of hot melt adhesive? In recent years, with the rapid development of e-commerce, logistics, packaging, labeling and other related industries have also experienced significant growth. The labeling industry and adhesive industry are driven by these industries and are areas that people see, use, and come into contact with every day. But […]
What is the reason why EVA hot melt adhesive does not stick? Some time ago, a customer asked us why we couldn’t stick books firmly when bonding. Through this small case, we will answer the question: What is the reason why hot melt adhesive does not stick? When bonding books, if EVA hot melt adhesive […]
