  • The significance of resin bonding line
    May 10, 2017

    (1) To minimize the pollution caused by waste sand removal, so that more than 90% of waste sand can be recycled. 

    (2) Due to the smooth surface of recycled sand particles, the particle size distribution evenly, small powder, can save more than 20%% of the resin. 

    (3) The regenerative sand heat stability is good, the heat expands less, the chemical property is stable, the acid consumption value decreases, the resin sand performance is easy to control, is advantageous to improve the casting quality, reduces the pulse pattern, the mechanical sticky sand and so on defects.
