What are the characteristics of the Purification Filter Glue Series
source：www.gerwilo.cn | Release time：2025年03月05日1. Characteristics before curing
Low viscosity: For example, the sealing adhesive for the air filter liquid tank has a low viscosity before curing, usually between 1000-2000mpa. s, and has good flowability. It can be easily filled into various gaps and corners of the purification filtration equipment, ensuring the integrity and sealing of the sealing.
Two component and easy to control ratio: It is mostly a two-component product, such as the A and B components of liquid tank jelly glue, which are usually mixed in a 1:1 weight ratio.
Sufficient operating time: There is sufficient operating time for users to perform the sealing operation, such as partial sealing operation time ≥ 25 minutes, in order to complete the sealing work of the purification and filtration equipment before curing.
2. Characteristics of curing process
No low molecular weight release: During solidification, no low molecular weight substances are produced, reducing pollution to the internal structure and environment of the purification and filtration equipment, and avoiding the possible decrease in sealing performance or equipment failure caused by low molecular weight volatilization.
Small shrinkage rate: The curing shrinkage rate is small, which can maintain the shape and size stability after sealing, and has a high degree of adhesion with the purification and filtration equipment. There will be no gaps or delamination due to shrinkage, ensuring the sealing and protection effect.
Non corrosive: It is non corrosive to various materials of purification and filtration equipment, such as metal, plastic, fiberglass, etc., and will not damage the structure and performance of the equipment, extending its service life.
3. Characteristics after curing
Good adhesion: It has good adhesion with aluminum, galvanized sheet, stainless steel, and various filter materials, and can firmly connect the filter element with the equipment frame, ensuring that there will be no looseness or detachment during use.
Sealing and self-healing properties: It has self-adhesive and self-healing properties, and the formed sealing layer can automatically restore some sealing performance even when it is damaged by a certain degree of external force or when small cracks appear, effectively preventing the leakage of gases, liquids, or impurities.
Weather resistance and stability: It has good weather resistance and aging resistance, can be used for a long time in the temperature range of -50-200 ℃, and has stable performance. It can adapt to different working environments and climate changes, ensuring the reliability of purification and filtration equipment during long-term use.
Insulation, moisture resistance, and shock resistance: With good insulation performance, it can prevent problems such as internal circuit short circuits in equipment; Simultaneously possessing moisture-proof and shockproof properties, it can protect the electronic and mechanical components in the purification and filtration equipment from the effects of moisture and vibration, improving the stability and safety of the equipment.
Good softness and elasticity: For example, after the solidification of liquid tank jelly glue, it has good softness and elasticity, can absorb the stress caused by thermal expansion and contraction without cracking, and can also buffer external mechanical impact to a certain extent, protecting the internal structure of purification and filtration equipment.
