Study on the Effect of Different Additive Ratio on the Properties of Resin Used for Sand Casting of Magnesium Alloy
In this study,for the resin sand used in magnesium alloy sand casting,the formulation and role of additives such as resin,curing agent,flame retardant,silane,etc.added during sand mixing were discussed.The effects of different additives ratio on the performance of resin sand were analysed by determining the serviceable time,mould starting time,compressive strength and other parameters of resin sand.The results of the study show that on the basis of ensuring the strength of resin sand,minimising the proportionate amount of resin and curing agent can reduce the casting porosity defects,improve the high temperature performance,improve the casting quality and reduce the production cost.This study provides technical support for the high quality production of magnesium alloy castings.
