For filters designed for different scenarios, using various types of adhesive can achieve better results. 

When selecting a suitable high-temperature sealant with a matching filter, consider the following factors: 

✅High-Temperature Performance: First, choose a sealant that can withstand high temperatures. Generally speaking, the higher the sealant's high-temperature resistance, the greater its stability in hot environments. You can select a sealant with appropriate high-temperature performance based on the filter's operating temperature range. 

✅ Viscosity and Fluidity: Viscosity is an indicator that measures the fluidity of sealants—higher viscosity means poorer fluidity. When selecting a sealant, it’s essential to consider the specific operating conditions of the filter, choosing one with appropriate viscosity and fluidity to ensure ease of application and achieve excellent sealing performance. 

✅Chemical Stability: The high-temperature-resistant sealing adhesive used in filters must be capable of withstanding erosion from various chemicals, ensuring the filter's long-term stable operation. Therefore, when selecting a material, it's essential to pay attention to the chemical stability of the sealing adhesive, especially in environments with highly corrosive conditions. 

Recommended key adhesive applications for industrial filters: 

Filter material and end cap bonded seal 

Recommended adhesive: Polyurethane potting compound or epoxy resin potting compound, Polyurethane For ambient-temperature cartridges requiring rapid curing, it is necessary 30 Minutes can solidify and flip, making them suitable for assembly-line operations. They offer a wide temperature resistance range ( -40℃ to 80℃ ), resistant to shock and vibration, with excellent adhesion to metal end caps—making them unlikely to detach; Epoxy resin For high-temperature filter cartridges, the ultra-high-temperature-resistant epoxy resin potting compound can withstand 250℃ The temperature. 

Dust removal filter bag stitching line pinholes sealed with glue, achieving zero emissions. 

Recommended adhesive: Silicone Sealant , fast curing, 8 Second -3 Minutes—extremely fast curing speed, with long-term durability. 280℃ High temperature. 

Sintered plate splicing and bonding, end cap sealing and bonding 

Recommended adhesive: Two-component epoxy resin structural adhesive ， HNEP 6225-25 ， 5:2 Mixing ratio, low cost, strong adhesion—Shanghai Hinnel HNEP6220-6 Epoxy resin structural adhesive, featuring high-temperature resistance, excellent toughness, and strong bonding performance. 

Dust removal equipment metal casing sealing 

Recommended adhesive: Organosilicon adhesive sealant, with strong elastic deformation capability, compensates for thermal expansion and contraction of metals. 

Wear-resistant lining plate installation for dust removal equipment 

Recommended adhesive: Epoxy resin structural adhesive, resistant to dust erosion, enhancing durability and lifespan. 3 More than double. 

Things to keep in mind when using glue 

1 Adhesive should be stored under conditions with lower ambient temperatures, and ensure thorough mixing before use. 

2 Choose the appropriate glue model and batch, as different batches of glue may yield varying results. 

3 When using glue, be careful not to touch the filter layer of the filter, and avoid dripping excessive amounts of glue to prevent compromising the filter's performance. 

With growing environmental awareness and advancing technology, there is vast potential for development in adhesive solutions used for industrial dust filtration systems. High-efficiency filters require the right type of adhesive—different filter categories call for distinct adhesives. Proper storage and handling of adhesives are essential to maintaining optimal filter performance. Choosing premium-quality adhesives not only enhances filtration efficiency but also helps reduce environmental pollution, paving the way for sustainable industrial growth.
