Proportion of unsaturated resins to curing agents and accelerators
Increase the dosage of accelerator, can obviously accelerate the curing rate; increase the proportion of curing agent, also can shorten the curing time.Above formula, curing time is about 3 minutes, curing time is affected by temperature.The influence of adding aluminum powder and calcium powder on the resin, accelerator and curing agent is negligible.In the process of forming, the artificial marble should control the time of product fixation, the curing time is short, the product is brittle, and the performance of the product is affected.Resin artificial marble production process will produce finished shrinkage, shrinkage rate of less than 7%.
Accelerator too much, the curing time is shortened, the product of crisp, serious will crack. The amount of curing agent is inversely proportional to the curing time of the resin. During operation, attention should be paid to the accelerator and curing agent not to be mixed directly so as to avoid violent chemical reaction. Do not put it together when you deposit it.
The general ratio is: resin: accelerator: curing agent =100:3:3, its filling material can be controlled in less than 120 copies. There is no proportion between the curing agent and the promoter.
The curing agent and accelerator are dependent on the amount of resin used. The curing agent and accelerant react only with the resin without chemical reaction with the stone powder and aluminum powder.
