Development and Application of Self-hardening Transferring Coating Material with Sagging Pattern to Moulds
With silica powder as refractory material, an acid phosphate as bonder and,magnesia as curing agent, hereafter , we consequently got an optimal ingredient ratio by applying orthogonal experiment.It is good to be used as sagging pattern to moulds with self hardening transfering coating material. After production test it has been proved that good properties of the coating can be obtained.
