What is the Purification Filter Glue Series

source：m.gerwilo.cn | Release time：2025年02月19日

The purification filtration filling series usually refers to a series of sealing adhesives and related supporting materials, processes, etc. used in the manufacturing process of purification filtration equipment. The following is a specific introduction:
1. Main product types
Liquid tank potting adhesive: generally, it is a low viscosity, viscous, gel like transparent two-component addition silicone potting adhesive, such as the addition silicone of Jiajinghong silicone. A. B component is a liquid with fluidity. A adhesive is transparent, B adhesive is blue, and different colors can be adjusted according to customer requirements. Mix 1:1 and stir evenly before curing at room temperature.
Polyurethane adhesive: such as YU1118 from Shanghai Weigu, it is a white, non foaming, waterless, room temperature curing polyurethane adhesive with high bonding strength, good flowability, fast solidification, and no unpleasant odor.
2. Product features
Good sealing performance: It can form a tight seal between various components of the filtration equipment, prevent gas, liquid and other leaks, and ensure the efficient operation of the purification filtration system. For example, after the liquid tank sealant solidifies, it can form a closed and airtight sealing effect in the aluminum tank.
Excellent adhesion performance: It has good adhesion to various materials such as metal, plastic, and fiber, and can firmly connect the various components of the filter together, ensuring the stability of the filter structure.
Chemical stability: It has good weather resistance and corrosion resistance, can maintain stable performance under different environmental conditions, is not easily corroded by chemical substances, and extends the service life of purification and filtration equipment.
Specific physical properties: Depending on different application scenarios, adhesive products may have appropriate physical properties such as softness, hardness, and elasticity. Some sealing adhesives have moderate softness and hardness, good elasticity recovery, and can absorb the stress caused by thermal expansion and contraction without cracking.
3. Application scenarios
In the field of air purification： it is widely used in high-efficiency air filters, including the manufacturing of medium and high-efficiency filters with partitions, no partitions, FFU, V-shaped filters, dust removal filter cartridges, etc., used for the bonding and sealing of filter materials and frames and other components.
In the field of liquid filtration: In some liquid filtration equipment, the glue filling series products can be used to seal the gap between the filter element and the housing, prevent liquid leakage, and ensure filtration effect.
4. Related processes and equipment
Glue filling process: including two methods: manual glue filling and machine glue filling. The manual gluing operation is relatively flexible and suitable for small-scale production or maintenance; Machine glue filling has the advantages of high efficiency, high precision, and uniform glue filling volume, making it suitable for large-scale industrial production.
Glue filling equipment: Common ones include vacuum glue filling machines, AB glue filling machines, etc. The vacuum glue filling machine can fill glue in a vacuum environment, effectively preventing the generation of bubbles and improving the quality of glue filling. It is mainly used for products with high requirements for glue filling process.
