Water glass casting baffle

Laminated sand, pig iron laminated sand, aluminum casting laminated sand particles surface covered with solid resin film type sand or core sand. There are two types of laminated sand casting process: cold method and hot method. The cold method uses alcohol to dissolve the resin. Please add uroto products in order to cover the surface of sand grains both must be clad sand in order to evaporate alcohol. Add uroto solution and lubricating liquid, preheat the sand to a certain temperature, add resin to melt, mix so that the resin covers the sand surface cooling, crushing and screening the laminated sand. Due to the cost of the product, the thermal coating process is mostly used at present. Clad sand casting is used for cast steel parts.

Second, the main features.

1. Vibrating sand cleaning. High toughness. Low air emission. Low expansion

2. High looseness. High smoothness of casting surface

3. No cracking of shell shape. Good thermal stability. Good heat transfer. Good fluidity

4... No cracking of shell type... Good thermal stability... Flat casting surface. Good heat transfer

5. High toughness. Heat resistance. Low expansion... Good moldability. Good resistance to slagging

6. Uniformity of shell layer without decrusting. Fast drying speed
