Hot Melt Adhesive For Oil And Fuel Filter The bonding of automobile filter is mainly in filter core origami, omental fixation, end cap bonding, filter joint bonding, frame bonding and so on. A few simple examples: Hot Melt Adhesive Glue, Hot Melt Glue For Air Filter, Hot Melt Adhesive For Oil And Filter Shenzhen Tongde New Materials Technology Co., Ltd. , https://www.tdhotmeltglue.com
1. Filter element origami bonding
The bonding of filter origami requires the viscosity of hot melt adhesive to remain stable at the set temperature value and the fluidity to be uniform after full melting. Make sure it does not produce bubbles. After coating the adhesive liquid, it is necessary to put the material into the drying oven to observe the change of the adhesive paper without displacement or deformation;
2, filter joint bonding joint
This step refers to the filter membrane end connector and the joint on both sides of the filter membrane bonding, ordinary filters generally use EVA hot melt adhesive, PO hot melt adhesive, PA hot melt adhesive, air filters usually use EVA or PO hot melt adhesive, and oil filters are now mostly connected with PA polyurethane hot melt adhesive.
3, air conditioning filter - border bonding
Hot melt adhesive is also very suitable for the filter membrane and filter frame bonding seal, each processing plant filter specifications are not the same, some filter manufacturers like to use a hot melt adhesive machine with a scraper inside the filter frame evenly scrape hot melt adhesive and then manually paste the edge strip to the filter element around. This operation is normal for larger processing plants. Most of the glue used for sealing the edge of the air conditioner filter is EVA hot melt adhesive, which requires good hot melt adhesive fluidity, high bonding strength and excellent temperature resistance.
