What are the factors that affect the effect of water explosion of coated sand

The sand blasting process of coated sand equipment is an important technology in foundry industry in China. It is the casting heat immersed in water, the waste heat after casting, through the use of sand core expansion, so as not to let the sand core water explosion through external forces. At the same time, the film sand equipment is wet work, in addition to the vibration of the manual core, high efficiency, less dust, low noise, providing a good condition for the working environment.Sand blasting equipment greatly improves the working conditions of workers and reduces the dust of dust. At the same time, the cleaning efficiency is greatly improved, the turnover of the production area and modeling tools is accelerated, the production cycle is shortened, and the output per unit area is increased. However, with the hydraulic sand blasting equipment and the regeneration of the old sand, it has brought difficulties and problems to the sewage sludge treatment. In addition, if in the improper selection process, it can not cause water explosion or casting cracks. It is also very important to choose the process of water explosion film sand equipment for cast iron.
