Gasket Making Machine Principle Of Polyurethane Foam:
Mixing time:The time when components A and B are mixed Reaction time: The time when the foam begins to react with each other (about 15-60 seconds later) Foaming time: The time when the volume starts to expand and then foams into seals (about 15-180 seconds later) Drying time : Sealing strip at room temperature (25 ºC) under the condition of its surface has no sticky, and not damage to the surface after hitting time (about 2-20 minutes later) Available time:The time when the seal can be compressed or the parts can be assembled (about 20-12 hours later)
Gaske Making Machiane Advantages: 1. Temperature holding system- no need air conditioner room 2. Tapping water cleaning system- no need chemical cleaning liquid 3. Patented Anti-blocking gluing nozzle-no need extranozzle cleaning expense
