About the choice of adhesive, according to the working environment of refrigerant, this selection should have good seal performance, room temperature curing speed, good water resistance, high bonding strength, resistance to temperature of 120 ℃, in boiling water for 4 hrs strength without too big change, and soak in water for a long time that still can maintain its good sealing performance.

2. Design the formula of refrigerant adhesives;

3. The surface treatment: wash the decontamination with acetone, and fine grinding gently, then clean with acetone;
