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.
Misconception 1: Only performing room temperature peeling is considered qualified Many packaging factories only conduct peel tests at room temperature of 25 ° C and pass if they feel they cannot be peeled off. In fact, the transportation of color printed corrugated cardboard boxes requires extreme conditions such as high temperature carriages (50 ° C+), […]
EVA polymer hot melt adhesive is solvent-free, anhydrous, and 100% solid meltable. Main ingredients: resin, adhesive, viscosity modifier, antioxidant, etc. Fischer Tropsch wax in productionEVA hot melt adhesiveAs a viscosity modifier, it mainly reduces the viscosity of polymers and increases fluidity. EVA hot melt adhesiveTypes of viscosity modifiers: Commonly used viscosity modifiers include paraffin wax, […]
How to distinguish the quality of book binding glue? The hot melt adhesive used in books is divided into backing adhesive and edge sealing adhesive According to the thickness of different materials of paper and books, book adhesives with different viscosities and flow effects can be used to complete the bonding work of book pages. […]
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, […]
