4. Factors that affect the performance of 33LV in rapid curing systems
4.1 Temperature
Temperature is an important factor affecting the catalytic effect of 33LV. Generally speaking, the higher the temperature, the faster the reaction speed. However, excessively high temperatures may cause the reaction to get out of control and affect product quality. Therefore, in practical applications, the reaction temperature needs to be reasonably controlled according to specific process requirements.
| Temperature (°C) | Gel Time (s) | Foam structure |
|---|---|---|
| 20 | 120 | Alternate |
| 30 | 90 | Alternate |
| 40 | 60 | Alternate |
| 50 | 40 | Ununiform |
4.2 Catalyst dosage
The amount of catalyst is used directly affects the reaction rate. A moderate amount of 33LV can significantly accelerate the reaction, but excessive use may lead to excessive reaction and affect the foam structure. Therefore, in practical applications, it is necessary to reasonably control the amount of catalyst according to specific process requirements.
| Catalytic Dosage (%) | Gel Time (s) | Foam structure |
|---|---|---|
| 0.5 | 120 | Alternate |
| 1.0 | 90 | Alternate |
| 1.5 | 60 | Alternate |
| 2.0 | 40 | Ununiform |
4.3 Raw material ratio
The raw material ratio of polyurethane materials directly affects the reaction speed and product performance. A reasonable raw material ratio can ensure smooth reaction and form a uniform and delicate foam structure. In actual application, it is necessary to reasonably adjust the raw material ratio according to specific process requirements.
| Isocyanate/polyol ratio | Gel Time (s) | Foam structure |
|---|---|---|
| 1:1 | 120 | Alternate |
| 1:1.2 | 90 | Alternate |
| 1:1.5 | 60 | Alternate |
| 1:2 | 40 | Ununiform |
4.4 Stirring speed
The stirring speed affects the mixing uniformity of the raw materials, and thus affects the reaction speed and foam structure. Appropriate stirring speed can ensure that the raw materials are fully mixed and form a uniform and delicate foam structure. In practical applications, the stirring speed needs to be reasonably controlled according to specific process requirements.
| Agitation speed (rpm) | Gel Time (s) | Foam structure |
|---|---|---|
| 500 | 120 | Alternate |
| 1000 | 90 | Alternate |
| 1500 | 60 | Alternate |
| 2000 | 40 | Ununiform |
