Agent EVA FOAM MANUFACTURER dosage of 11 copies
In theory : Molded time is too short , there mucous membranes, foam timber bottom rupture. The reason is: when the cross -linking time is short, the degree of crosslinking is low, foam material mucosa, with EVA FOAM MANUFACTURER increase in the amount of the decomposition gas , low cross -linked EVA FOAM MANUFEVA FOAM MANUFACTURERTURER strong to bear the impact of the fracture pressure ; If the molding time is too long, resulting crosslinked products through the large, foam material shrinkage occurs [ 5 ] .

The maximum temperature of the kneaded material DCP cross-linking reaction of the corresponding half-life of 10 minutes the temperature of the decision , the crosslinking temperature will have to consider DCP, EVA FOAM MANUFACTURER gels and the amount of their relationship , and ultimately to be determined . If the temperature is too high , DCP crosslinking EVA FOAM MANUFACTURER temperature and the decomposition rate is too high , resulting in molding time is difficult to control ; temperature is too low , resulting in EVA FOAM MANUFACTURER DCP decomposition rate and the crosslinking rate are incompatible , the coagulation system, gel content less than 65% , you can not get a good EVA foam manufEVA foam manufacturerturer body . Therefore, reducing the molding temperature, so EVA FOAM MANUFACTURER decomposition rate and DCP crosslinking rate are reduced, molded products, extended time [ 6 ] .
3 Conclusions
Based on the above aspects of the factors, the best experimental molded EVA foam manufEVA foam manufacturerturer conditions : EVA foam manufEVA foam manufacturerturer agent EVA FOAM MANUFACTURER dosage of 11 copies, the DCP crosslinking amount of 0.5 parts , EVA foam manufEVA foam manufacturerturer temperature was 165 ℃, EVA foam manufEVA foam manufacturerturer pressure is 15MPa, EVA foam manufEVA foam manufacturerturer time of 15 minutes.
