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.
The role and key elements of bookbinding adhesive in binding are the key to the quality of bookbinding! Hot melt adhesive becomes brittle when cooled, the back adhesive layer is not smooth, and insufficient penetration of the adhesive liquid leads to non stick properties. These are the issues that most books and publications face when […]
EVA hot melt adhesive, which is brittle in winter and prone to cracking in summer, belongs to the normal characteristics of thermoplastic materials and is not a product quality issue. It is strongly recommended to prioritize adjusting equipment temperature and production processes, and replace seasonal adhesive when the environment is extreme. At the same time, […]
Book edge glue is an important but often overlooked application of book binding glue. Simply put, it refers to using a thin layer of hot melt adhesive to bond the inside of the cover to the first, last, or final page of the book. Although side bonding is much smaller in volume than spine bonding, […]
Direct answer:Hot melt adhesive particles belong to thermoplastic materials and can theoretically be melted repeatedly, but in most cases, “recycling and reuse” on the production site is not cost-effective or safe.There is only one situation that can be recycled – clean residue that has never been used on the machine and has not been contaminated; […]
