水玻璃砂是一种化学硬化砂,生产周期短,干燥过程快,而且不需任何烘干的燃料和设备。如果把它和泥型一起并用,在泥型多铸多产方面能起到一定的作用。因为,泥型只要经过一次烘干就可多次使用,水玻璃砂在生产周期上有着相同的作用。 Sodium silicate sand is a chemical hardened sand, short production cycle, fast drying process, and does not require any drying of fuels and equipment. If you use it together with the muddy, cast in the mud more productive can play a role. Because, as long as the clay can be used repeatedly after drying, sodium silicate sand production cycle have the same effect.
