Or semi-transparent clear shape, hardness 7.6, the crisp no cleavage of property, conchoidal fracture, greasy luster, relative density 2.67, chemistry, heat
It learns and mechanical performance has apparent anisotropy, insoluble in acid, be slightly soluble in potassium hydroxide solution, 1750 DEG C of fusing point.
Quartz sand is very important one of nonmetallic ore raw material, non-chemical dangerous material, its unique object
Reason, chemical property, so that it is in glass, casting, ceramics and fire proofing material, smelting duriron, flux for metallurgy, metallurgy, building, change
Work, plastics, rubber, abrasive material, the industrial circles such as filtrate play irreplaceable role.
3D printing technique is a kind of rapid shaping technique, it is one kind based on digital model file, and utilization is powdered
Adhesive material constructs the technology of object by layer-by-layer printing.Usually using digital technology file printing machine come
It realizes.In forming process, first powder particle and curing agent are mixed, then complete the fixed powder of a layer thickness
Grain material, then being injected in binder selectivity on the powder particle layers completed by spray head repeat this operation, in layer
It stacks up, it is final to realize solidification molding bonded.
However existing 3D printing dusty material is mainly stone molding powder end, nylon, precoated sand etc., manufacturing cost is higher, valence
Lattice are expensive, are unfavorable for industrial application in industry.
Summary of the invention
That there are manufacturing costs is high, expensive, it is strong to print physical components for 3D printing material in the prior art by the present invention
