2. Characteristics of Baozhu sand Mining Machine Spare Parts:
(1) The coefficient of thermal expansion is small, the performance can be comparable with zircon sand, with its configuration sand, casting will not produce expansion defects;
(2) The sand is spherical, with good fluidity and good air permeability;
(3) The surface is smooth, the structure is compact, so that the adhesive can cover evenly;
(4) Baozhu sand belongs to neutral materials, acid, alkali adhesives can be used;
(5) Good reuse and regeneration performance, high cost performance;
