| titleOfInvention | A kind of preparation method of mould sand for environmental-protecting type casting |
| abstract | The invention discloses a kind of preparation methods of mould sand for environmental-protecting type casting, mainly press 95 118 by aggregate and binder：58 mass ratio is uniformly mixed, and the aggregate is grouped as by the group of following parts by weight：45 56 parts of CRT panel glass processed material, 25 30 parts of graphite sand, 16 20 parts of zircon sand, 9 12 parts of rosin rock powder, wherein the preparation method of the CRT panel glass processed material includes the following steps：（1）The CRT panel glass of recycling is crushed to grain size 3mm or less；（2）CRT panel glass after crushing is continuously stirred into 5 minutes granular panel glass derived above；（3）Above-mentioned granular panel glass is sieved.The preparation method of mould sand for environmental-protecting type casting provided by the invention, obtained molding sand high mechanical strength, thermo-chemical stability are good, and adhesive property protrudes, gas permeability is preferable, casting condensation rate is uniform, and cast(ing) surface is not likely to produce crackle and shrinkage cavity after condensation, is particularly suitable for production quality and requires high casting. |
